 STATE AND THEN THE COLDER AIR IS FORECAST TO SWEEP THROUGH.                    
 NOT TOO MANY CHANGES NEEDED TO THE GOING FORECAST OTHER THAN TO

 WIND...JUST BITTERLY COLD. MIGHT SEE SOME PATCHY FREEZING FOG IN THE           
 LOW LYING AREAS LIKE THE LOWER AR RIVER AND SAN LUIS VALLEY. SHOULD            
 SEE A MIX OF CLOUDS AND SUN TODAY... LEANING MORE TOWARDS SUN. BIG             
 CHALLENGE WITH ARCTIC AIR MASS IN PLACE...SNOW COVER...TERRAIN...AND           
 VERY LITTLE WIND POTENTIAL FOR MIXING WILL BE MAXIMUM TEMPERATURES.

 THE EXTENDED.  WEAKENING UPPER LOW REMAINS OFF TO THE SOUTHWEST                
 THIS DAY WITH VERY LITTLE MOISTURE ASSOCIATED WITH IT.  THUS REGION

 RETREAT TO THE EAST AND BOTH GFS/NAM MODERATING LOWER LVL TEMPS                
 DURING THE DAY.  HOWEVER SFC WINDS SHOULD STAY LIGHT AND WITH FRESH            
 SNOW COVER FROM YESTERDAY`S STORM...THINK IT WILL HAVE A DIFFICULT             
 TIME GETTING ABOVE FREEZING...ESP SAN LUIS VALLEY AND KLAA AREA.

 SYSTEM...WITH ONLY SOME ISOLATED SNOW SHOWERS POSSIBLE FOR THE SOUTHWEST       
 AND CENTRAL MOUNTAINS.  MAIN AFFECT THIS SYSTEM WILL HAVE ON THE               
 EAST IS TO INDUCE LEE TROFFING WHICH WILL HELP INCREASE WINDS AND              
 BRING A WARM UP TO THE REGION AND BEGIN TO MELT SOME OF THE SNOW BY            
 WED. WITH DRY AIR MASS OVER THE REGION...EXPECT TEMPS TO DROP                  
 QUICKLY TUES EVENING...WITH LOWS ALONG THE EASTERN SLOPES PROBABLY             
 OCCURRING AROUND MIDNIGHT...THEN WARMING TOWARDS MORNING AS DRAINAGE

 THE SRN STREAM ENERGY CUTS OFF AND SINKS SOUTHWARD OFF THE SRN CA              
 COAST.  THIS SOLUTION HAS TRENDED TOWARDS THE 00Z ECMWF SOLUTION FROM          
 LAST NIGHT.  LATEST 00Z ECMWF FAIRLY SIMILAR TO THE LATEST GFS                 
 RUN...AND VAST MAJORITY OF THE GFS ENSEMBLE MEMBERS SUPPORT THIS               
 TREND.  THIS WOULD MEAN SYSTEM FOR THURS WILL BE MUCH LESS OF A                
 PLAYER FOR PRECIPITATION ACROSS THE AREA...BRINGING A BRIEF SHOT OF            
 SNOW TO THE CENTRAL MOUNTAINS WED NIGHT...AND ANOTHER SHOT OF COLD             
 TO THE SOUTHEAST PLAINS.  GIVEN SOME CONTINUITY BETWEEN

 MAIN CONCERNS ARE PRECIP TYPE AND AMOUNTS OF ICE OR SNOW ACCUM THE             
 REST OF THE NIGHT AND TOMORROW MORNING. THE BACK EDGE OF THE MAIN              
 AREA RAIN AND FREEZING RAIN SEEMS TO BE APPROACHING OUR SW CWA                 
 SOON. IR SATELLITE IMAGES SHOW BANDED WAVES HELPING TO GENERATE ENHANCE        
 PRECIP ACROSS EASTERN MISSOURI AND WEST CENTRAL ILLINOIS ATTM.                 
 THIS PUSH IS MATCHING UP WELL WITH THE BACK EDGE OF THE MAIN AREA              
 OF RAIN. FEEL THERE WILL BE A BIG DROP OFF IN MEASURABLE RAIN AND              
 FREEZING RAIN AFTER MIDNIGHT IN MUCH OF CENTRAL ILLINOIS. THERE                
 DOES APPEAR TO BE ADDITIONAL MOISTURE AND COLD CLOUD TOPS BEHIND               
 THIS RAIN BAND. THE INVERTED TROUGH HAS YET TO ENTER INTO ILLINOIS             
 AS WELL...SO LIGHT RAIN...FREEZING RAIN...OR SNOW SHOULD CONTINUE              
 INTO MONDAY MORNING...BUT AT MUCH SLOWER RATES THAN THIS EVENING.              
 WORKING ON UPDATING THE GRIDS FOR PLACEMENT OF THE MOST FREEZING               
 RAIN AND SNOW. FREEZING LINE SEEMED TO BE PERSISTING MUCH FARTHER              
 NORTHWEST THAN PREVIOUSLY EXPECTED. I SEE THE BLOOMINGTON HAS JUST             
 NOW FINALLY REPORTED FREEZING RAIN...BUT LINCOLN REMAINS 34 AND                
 SPRINGFIELD IS 35. THAT CORRIDOR OF CENTRAL ILLINOIS IS A TOUGH                
 CALL ON WHEN THEY WILL GO BELOW FREEZING. RUC METEOGRAMS ARE                   
 KEEPING SPI ABOVE FREEZING THROUGH AT LEAST 12Z...SO I AM HAVING               
 TROUBLE FORECASTING ICE ACCUM THERE. WILL GO ON PREMISE THAT                   
 ELEVATED TREE LIMBS AND POWER LINES WILL SEE FREEZING AND ICE                  
 ACCUM...AND THAT IS WHERE THE PUBLIC IMPACT WILL BE GREATEST...IF              
 THE BRANCHES BREAK AND POWER LINES COME DOWN.                                  
 IN KNOX...STARK AND NORTHERN FULTON COUNTIES...TEMPS HAVE REMAINED             
 BELOW FREEZING DURING THE RAIN THIS EVENING...AS ICE ACCUMS ON                 
 TREES AND POWERLINES ARE NEARING A QUARTER INCH. NORTHWEST WINDS               
 HAVE SUBSIDED TO LESS THAN 10 MPH IN MOST AREAS...BUT STILL SOME               
 SWAYING OF THE TREES MAY CAUSE BRANCHES TO SNAP. SNOW AMOUNTS IN               
 THAT AREA SHOULD NOT CLIMB MUCH OVER AN INCH...AS THE BULK OF THE              
 PRECIPITATION WILL BE OVER BEFORE THE SNOW STARTS ACCUMULATING.                
 WILL KEEP THE WINTER WEATHER ADVISORY GOING AS IS...WITH THE                   
 FREEZING RAIN THROUGH MIDNIGHT...THEN THE FREEZING DRIZZLE OR SNOW             
 THE REST OF THE NIGHT...ESPECIALLY NORTHWEST OF THE ILLINOIS                   
 RIVER...AND LESS ICE AND SNOW BETWEEN THE ILLINOIS RIVER AND THE               
 I-55 CORRIDOR. EAST OF I-55 WILL NOT SEE MUCH FREEZING RAIN                    
 THROUGH MIDNIGHT. PRECIP IN THAT AREA WILL CHANGE TO DRIZZLE OR                
 SCATTERED RAIN SHOWERS AFTER MIDNIGHT UNTIL MORNING...THEN MIX                 
 WITH OR CHANGE TO SNOW DURING THE MORNING.

 WINTER WEATHER SYSTEM IS MAIN CONCERN...WITH PCPN TYPE OVERNIGHT AS            
 THE SYSTEM CONTINUES AS PLANNED JUST WITH LITTLE WARMER SURFACE                
 TEMPS THAN ORIGINALLY THOUGHT. HOWEVER SFC TEMPS ARE STILL 1-2 DEGS            
 BELOW NAM AND GFS MODEL. SO...ACTUALLY APPEARS THAT SFC TEMPS VERIFY           
 BEST WITH EITHER NGM OR THE RUC MODELS. THEREFORE WILL FOLLOW THOSE            
 IN THE VERY SHORT TERM AND THEN ADJUST NAM/GFS FURTHER OUT.                    
 SHORT TERM...TONIGHT THROUGH WEDNESDAY...                                      
 SFC LOW SITTING IN WESTERN ARK AT 20Z AND IS SHOWING SIGNS OF                  
 DEEPENING AS SFC HEIGHT FALLS OF 4 TO 5 MB IS SEEN IN THE SFC DATA             
 TO THE NORTH ACRS SOUTHERN MO AND INTO NERN KS. A SFC TROUGH IS ALSO           
 EVIDENT IN THE SFC DATA FROM SOUTHERN IL INTO EASTERN IA.                      
 THEREFORE...NEUTRAL TEMP ADVECTION CAN BE EXPECTED INTO THE EARLY              
 EVENING HOURS. THIS MEANS THAT MOST OF PCPN MOVING INTO AREA WILL              
 START AS RAIN AND THEN CHANGE TO FREEZING RAIN...FROM WEST TO                  
 EAST...AS THE NIGHT PROGRESSES. BELIEVE AREAS ALONG AND NORTHWEST OF           
 IL RIVER WILL QUICKLY CHANGE TO FREEZING RAIN THIS EVENING AND THEN            
 MIX WITH SLEET BEFORE CHANGING TO SNOW BY MIDNIGHT. AREAS ALONG I-55           
 WILL START AS RAIN AND THEN CHANGE TO FREEZING RAIN BEFORE MIDNIGHT            
 AND THEN MIX WITH SOME SLEET AND SNOW AFTER MIDNIGHT. AREAS TO THE             
 EAST WILL SEE ALL RAIN UNTIL MIDNIGHT AND THEN CHANGE TO A MIX OF              
 FREEZING RAIN AND SLEET AFTER MIDNIGHT BEFORE CHANGING TO SNOW IN              
 THE MORNING. WITH THE LINE OF FREEZING RAIN/SLEET BETWEEN RAIN STILL           
 BEING ALONG A BLOOMINGTON TO DECATUR TO TAYLORVILLE LINE...WILL                
 LEAVE THE WINTER WEATHER ADVISORY AS IS...BUT JUST CHANGE THE ENDING           
 TIME TO NOON TOMORROW. WITH SYSTEM LIFTING NORTHEAST TONIGHT AND               
 LITTLE FURTHER NORTH THAN ORIGINALLY THOUGHT...SNOWFALL AMOUNTS WILL           
 BE ON THE ADVISORY SIDE OR LESS IN MOST AREA. TOTAL SNOWFALL WILL BE           
 AN INCH OR LESS ALONG I-72 CORRIDOR WITH HIGHER AMOUNTS FURTHER                
 NORTH...REACHING TO JUST UNDER 4 INCHES IN THE FAR NORTH OF THE CWA.           
 PIA AROUND 2 INCHES AND BLOOMINGTON AROUND 1.5 INCHES.                         
 PCPN WILL END DURING THE DAY TOMORROW WITH LITTLE IF ANY ADDITIONAL            
 ACCUMULATION OF EITHER SNOW OR ICE. STILL AREAS IN THE SOUTHEAST               
 COULD STILL BE WARM ENOUGH THAT THE PCPN COULD BE A MIX OF RAIN AND            
 SNOW.

 .DISCUSSION...                                                                 
 WINTER WEATHER SYSTEM IS MAIN CONCERN...WITH PCPN TYPE OVERNIGHT AS            
 THE SYSTEM CONTINUES AS PLANNED JUST WITH LITTLE WARMER SURFACE                
 TEMPS THAN ORIGINALLY THOUGHT. HOWEVER SFC TEMPS ARE STILL 1-2 DEGS            
 BELOW NAM AND GFS MODEL. SO...ACTUALLY APPEARS THAT SFC TEMPS VERIFY           
 BEST WITH EITHER NGM OR THE RUC MODELS. THEREFORE WILL FOLLOW THOSE            
 IN THE VERY SHORT TERM AND THEN ADJUST NAM/GFS FURTHER OUT.                    
 SHORT TERM...TONIGHT THROUGH WEDNESDAY...                                      
 SFC LOW SITTING IN WESTERN ARK AT 20Z AND IS SHOWING SIGNS OF                  
 DEEPENING AS SFC HEIGHT FALLS OF 4 TO 5 MB IS SEEN IN THE SFC DATA             
 TO THE NORTH ACRS SOUTHERN MO AND INTO NERN KS. A SFC TROUGH IS ALSO           
 EVIDENT IN THE SFC DATA FROM SOUTHERN IL INTO EASTERN IA.                      
 THEREFORE...NEUTRAL TEMP ADVECTION CAN BE EXPECTED INTO THE EARLY              
 EVENING HOURS. THIS MEANS THAT MOST OF PCPN MOVING INTO AREA WILL              
 START AS RAIN AND THEN CHANGE TO FREEZING RAIN...FROM WEST TO                  
 EAST...AS THE NIGHT PROGRESSES. BELIEVE AREAS ALONG AND NORTHWEST OF           
 IL RIVER WILL QUICKLY CHANGE TO FREEZING RAIN THIS EVENING AND THEN            
 MIX WITH SLEET BEFORE CHANGING TO SNOW BY MIDNIGHT. AREAS ALONG I-55           
 WILL START AS RAIN AND THEN CHANGE TO FREEZING RAIN BEFORE MIDNIGHT            
 AND THEN MIX WITH SOME SLEET AND SNOW AFTER MIDNIGHT. AREAS TO THE             
 EAST WILL SEE ALL RAIN UNTIL MIDNIGHT AND THEN CHANGE TO A MIX OF              
 FREEZING RAIN AND SLEET AFTER MIDNIGHT BEFORE CHANGING TO SNOW IN              
 THE MORNING. WITH THE LINE OF FREEZING RAIN/SLEET BETWEEN RAIN STILL           
 BEING ALONG A BLOOMINGTON TO DECATUR TO TAYLORVILLE LINE...WILL                
 LEAVE THE WINTER WEATHER ADVISORY AS IS...BUT JUST CHANGE THE ENDING           
 TIME TO NOON TOMORROW. WITH SYSTEM LIFTING NORTHEAST TONIGHT AND               
 LITTLE FURTHER NORTH THAN ORIGINALLY THOUGHT...SNOWFALL AMOUNTS WILL           
 BE ON THE ADVISORY SIDE OR LESS IN MOST AREA. TOTAL SNOWFALL WILL BE           
 AN INCH OR LESS ALONG I-72 CORRIDOR WITH HIGHER AMOUNTS FURTHER                
 NORTH...REACHING TO JUST UNDER 4 INCHES IN THE FAR NORTH OF THE CWA.           
 PIA AROUND 2 INCHES AND BLOOMINGTON AROUND 1.5 INCHES.                         
 PCPN WILL END DURING THE DAY TOMORROW WITH LITTLE IF ANY ADDITIONAL            
 ACCUMULATION OF EITHER SNOW OR ICE. STILL AREAS IN THE SOUTHEAST               
 COULD STILL BE WARM ENOUGH THAT THE PCPN COULD BE A MIX OF RAIN AND            
 SNOW.                                                                          
 AFTER THIS SYSTEM MOVES OUT...COLDER AIR WILL ADVECT INTO THE                  
 AREA...WITH THE COLDEST TEMPS IN THE NORTH WITH THE SNOW COVER.                
 COLDEST TEMPS EXPECTED TO BE TUESDAY AND TUESDAY NIGHT AS CENTER OF            
 THE HIGH SETTLES OVER THE AREA...CLOUDS DISAPPEAR AND WINDS BECOME             
 LIGHT. THEN WEDNESDAY...TEMPS WILL SLOWLY CLIMB BACK TO NEAR NORMAL.           
 LONG TERM...THURSDAY THROUGH SUNDAY...                                         
 MODIFY ZONAL PATTERN WILL BECOME THE RULE DURING THE EXTENDED WITH             
 SEVERAL MINOR WAVES FORECAST TO MOVE ACRS THE AREA. WITH LITTLE                
 MOISTURE TO WORK WITH AND STILL SOME UNCERTAINTIES ON STRENGTH AND             
 TIMING OF WAVES...WILL KEEP EXTENDED DRY.                                      
 TEMPS THROUGH THE EXTENDED WILL REMAIN CLOSE TO NORMAL WITH A SLIGHT

 MAIN CONCERN FOR THE 00Z TAF CYCLE IS LAKE EFFECT SNOW                         
 TIMING/INTENSITY AT KSBN TERMINAL. FIRST...A GENERAL AREA OF LIGHT             
 SNOW WILL MOVE EAST THROUGH KSBN THE FIRST HALF OF TONIGHT...AND               
 PROBABLY REACH KFWA IN A WEAKENED STATE BY MID/LATE EVENING IN                 
 ASSOCIATION WITH APPROACH OF MID LEVEL TROUGH AXIS AND LOW LEVEL               
 ARCTIC FRONT. SEVERAL BANDS OF LAKE EFFECT SNOW ALREADY DEVELOPING             
 OVER THE NORTHERN HALF OF LAKE MICHIGAN SHOWN ON KGRB AND KGRR                 
 RADARS EARLY THIS EVENING. EXPECT THESE BANDS TO CONSOLIDATE INTO A            
 SINGLE BAND LATER THIS EVENING AS LOW LEVEL CONVERGENCE INCREASES              
 DOWN THE MAJOR AXIS OF LAKE MICHIGAN...AND THEN CURVE CYCLONICALLY             
 INTO NW INDIANA. TIMING DIFFICULT FOR KSBN TAF AT THIS EARLY                   
 JUNCTURE AS BAND MAY OSCILLATE EAST AND WEST AND CROSS THE TERMINAL            
 SEVERAL TIMES. BEST ESTIMATE IS HEAVIEST SNOW POTENTIAL IS LATE                
 TONIGHT THROUGH MID MORNING TUE. LATER SHIFTS CAN ADJUST AND ADD               
 VLIFR BASED ON RADAR TRENDS. HAVE ADDED A TEMPO MVFR GROUP AT KFWA             
 TUE AFTERNOON AS SINGLE BAND SHIFTS EAST AND BREAKS APART INTO                 
 MULTIPLE BANDS...SOME OF WHICH MAY CLIP KFWA TERMINAL FOR A FEW                
 HOURS.                                                                         
 A NOTE FOR THOSE LOOKING AT MESOSCALE MODEL OUTPUT FOR THIS LAKE               
 EFFECT SNOW EVENT...SUCH AS THE NAM-WRF...CANADIAN REGIONAL GEM...OR           
 THE FSL RUC. WE HAVE SEEN A SYSTEMATIC BIAS OF MESOSCALE MODELS                
 BEING TO FAR WEST WITH BAND PLACEMENT IN SINGLE BAND SITUATIONS. THE           
 VAST MAJORITY OF THE TIME THE LAKE EFFECT SNOW BAND VERIFIES 10 TO             
 20 NM EAST OF THE MESOSCALE MODEL BAND LOCATION...ASSUMING THE MODEL           
 HAS A GOOD HANDLE ON THE SYNOPTIC BACKGROUND FLOW.                             
 &&

 TONIGHT AND TUESDAY                                                            
 ...MAJOR LAKE EFFECT SNOW EVENT TONIGHT INTO TUESDAY...                        
 FORECAST CONCERN IN THE SHORT TERM REVOLVES AROUND LAKE EFFECT SNOW            
 POTENTIAL LATER THIS EVENING THROUGH TUE AFTERNOON. FIRST...OUTSIDE            
 OF LAKE EFFECT AREAS A BAND OF SNOW IS MOVING THROUGH THE N/NW                 
 PORTION OF THE CWA THIS AFTERNOON ALONG FIRST OF SEVERAL SECONDARY             
 COLD FRONTS. THE TRUE ARCTIC FRONT LIES OVER SOUTHERN WISCONSIN AND            
 CENTRAL LOWER MICHIGAN WITH REGIONAL RADARS SHOWING ANOTHER BAND OF            
 ENHANCED SNOW ALONG AND BEHIND THIS FEATURE. ALSO A LARGE AREA OF              
 LIGHT SNOW ASSOCIATED WITH DECAYING DEFORMATION AXIS UPSTREAM FROM             
 NORTHERN ILLINOIS INTO LOWER MICHIGAN. GIVEN LOOK OF UPSTREAM RADARS           
 AND EXPECTED PASSAGE OF MID LEVEL TROUGH AXIS AND ASSOCIATED LIFT...           
 MAY SEE A GENERAL LIGHT SNOWFALL ACROSS MOST OF THE CWA TONIGHT.               
 WILL PROBABLY END UP GOING WITH LOW LIKELY POPS AND A COATING OF               
 ACCUMS IN MOST AREAS...EXCEPT FOR THE FAR SOUTH.                               
 NOW FOR THE LAKE EFFECT. FORECAST SURFACE PRESSURE FIELDS SHOW A               
 CLASSIC PATTERN RECOGNITION FOR A BIG SOUTHERN LAKE MICHIGAN EVENT             
 WITH A 1040+MB ARCTIC HIGH BUILDING SOUTH DOWN THE PLAINS. UPSTREAM            
 RADARS SHOWING HEALTHY BANDS OF LAKE EFFECT SNOW DEVELOPING ON                 
 NORTHERLY FETCH OF LAKE SUPERIOR AND ANOTHER OFF GREEN BAY AFFECTING           
 THE DOOR PENINSULA. LAST FEW RUNS OF THE NAM-WRF AND THE FSL                   
 EXPERIMENTAL 13KM RUC HAVE BEEN REASONABLY CONSISTENT IN DEVELOPING            
 A WELL DEFINED SINGLE BAND TONIGHT DOWN THE LONG AXIS OF LAKE                  
 MICHIGAN. INSTABILITY IS VERY GOOD WITH LAKE INDUCED CAPES EXCEEDING           
 500J/KG AND EQUILIBRIUM LEVELS ABOVE 700MB. CLOUD BEARING LAYER AND            
 ASSOCIATED MODEL INDUCED OMEGA SHOWING A NICE BULLSEYE SIGNATURE               
 INTERSECTING THE FAVORED DENDRITIC SNOW GROWTH ZONE. MESOSCALE                 
 MODELS ALSO SUGGESTING AN UPSTREAM CONNECTION TO LAKE SUPERIOR FOR             
 AWHILE TONIGHT...WHICH IS A CLASSIC HALLMARK OF OUR BIG EVENTS AT              
 THE SOUTH END OF LAKE MICHIGAN. CONVERGENCE ALREADY BEGINNING TO               
 DEVELOP DOWN THE AXIS OF THE LAKE AS NOTED IN SURFACE OBS ALONG THE            
 E AND W SHORELINES...AND NAM-WRF STRENGTHENS LOW LEVEL CONVERGENCE             
 FIELD AS IT ARCS CYCLONICALLY INTO NW INDIANA AND SW LOWER MICHIGAN.           
 ALL SIGNS POINT TOWARDS THE POTENTIAL OF A MAJOR LAKE EFFECT SNOW              
 EVENT...WHICH HAS BEEN A RARITY AROUND HERE THE PAST FEW SEASONS               
 GIVEN THE WARM TEMPERATURES.                                                   
 THE FORECAST DETAILS...WILL BE UPGRADING THE LES WATCH TO A WARNING            
 FOR BERRIEN...CASS...ST JOSEPH...AND ELKHART COUNTIES. THE REMAINDER           
 OF THE COUNTIES IN THE WATCH WILL BE UPGRADED TO AN ADVISORY. MAY              
 SEE A RATHER INTENSE BAND ACROSS PARTS OF LAPORTE...STARKE...                  
 MARSHALL...AND KOSCIUSKO COUNTIES...HOWEVER EXPECT THE BAND TO                 
 REMAIN TRANSIENT THROUGH THESE COUNTIES AND NOT STAY OVER ONE SPOT             
 LONG ENOUGH TO DROP WARNING CRITERIA. IF IT BECOMES APPARENT THAT              
 THE BAND WILL GO STATIONARY FOR SEVERAL HOURS OVER ONE OF THESE                
 COUNTIES THAN AN UPGRADE MAY BE NEEDED. EXPECT THE MAJOR SINGLE BAND           
 TO BREAK APART INTO MULTIPLE BANDS...WEAKEN...AND SPREAD EAST ON TUE           
 AFTERNOON AS FLOW BACKS AND SYNOPTIC SCALE SUBSIDENCE INCREASES.               
 STORM TOTALS OF 6 TO 12 INCHES ARE POSSIBLE IN SOME LOCATIONS IN THE           
 WARNING COUNTIES...WITH LOCAL AMOUNTS OF OVER A FOOT POSSIBLE WHERE

 TONIGHT AND TUESDAY                                                            
 ...MAJOR LAKE EFFECT SNOW EVENT TONIGHT INTO TUESDAY...                        
 FORECAST CONCERN IN THE SHORT TERM REVOLVES AROUND LAKE EFFECT SNOW            
 POTENTIAL LATER THIS EVENING THROUGH TUE AFTERNOON. FIRST...OUTSIDE            
 OF LAKE EFFECT AREAS A BAND OF SNOW IS MOVING THROUGH THE N/NW                 
 PORTION OF THE CWA THIS AFTERNOON ALONG FIRST OF SEVERAL SECONDARY             
 COLD FRONTS. THE TRUE ARCTIC FRONT LIES OVER SOUTHERN WISCONSIN AND            
 CENTRAL LOWER MICHIGAN WITH REGIONAL RADARS SHOWING ANOTHER BAND OF            
 ENHANCED SNOW ALONG AND BEHIND THIS FEATURE. ALSO A LARGE AREA OF              
 LIGHT SNOW ASSOCIATED WITH DECAYING DEFORMATION AXIS UPSTREAM FROM             
 NORTHERN ILLINOIS INTO LOWER MICHIGAN. GIVEN LOOK OF UPSTREAM RADARS           
 AND EXPECTED PASSAGE OF MID LEVEL TROUGH AXIS AND ASSOCIATED LIFT...           
 MAY SEE A GENERAL LIGHT SNOWFALL ACROSS MOST OF THE CWA TONIGHT.               
 WILL PROBABLY END UP GOING WITH LOW LIKELY POPS AND A COATING OF               
 ACCUMS IN MOST AREAS...EXCEPT FOR THE FAR SOUTH.                               
 NOW FOR THE LAKE EFFECT. FORECAST SURFACE PRESSURE FIELDS SHOW A               
 CLASSIC PATTERN RECOGNITION FOR A BIG SOUTHERN LAKE MICHIGAN EVENT             
 WITH A 1040+MB ARCTIC HIGH BUILDING SOUTH DOWN THE PLAINS. UPSTREAM            
 RADARS SHOWING HEALTHY BANDS OF LAKE EFFECT SNOW DEVELOPING ON                 
 NORTHERLY FETCH OF LAKE SUPERIOR AND ANOTHER OFF GREEN BAY AFFECTING           
 THE DOOR PENINSULA. LAST FEW RUNS OF THE NAM-WRF AND THE FSL                   
 EXPERIMENTAL 13KM RUC HAVE BEEN REASONABLY CONSISTENT IN DEVELOPING            
 A WELL DEFINED SINGLE BAND TONIGHT DOWN THE LONG AXIS OF LAKE                  
 MICHIGAN. INSTABILITY IS VERY GOOD WITH LAKE INDUCED CAPES EXCEEDING           
 500J/KG AND EQUILIBRIUM LEVELS ABOVE 700MB. CLOUD BEARING LAYER AND            
 ASSOCIATED MODEL INDUCED OMEGA SHOWING A NICE BULLSEYE SIGNATURE               
 INTERSECTING THE FAVORED DENDRITIC SNOW GROWTH ZONE. MESOSCALE                 
 MODELS ALSO SUGGESTING AN UPSTREAM CONNECTION TO LAKE SUPERIOR FOR             
 AWHILE TONIGHT...WHICH IS A CLASSIC HALLMARK OF OUR BIG EVENTS AT              
 THE SOUTH END OF LAKE MICHIGAN. CONVERGENCE ALREADY BEGINNING TO               
 DEVELOP DOWN THE AXIS OF THE LAKE AS NOTED IN SURFACE OBS ALONG THE            
 E AND W SHORELINES...AND NAM-WRF STRENGTHENS LOW LEVEL CONVERGENCE             
 FIELD AS IT ARCS CYCLONICALLY INTO NW INDIANA AND SW LOWER MICHIGAN.           
 ALL SIGNS POINT TOWARDS THE POTENTIAL OF A MAJOR LAKE EFFECT SNOW              
 EVENT...WHICH HAS BEEN A RARITY AROUND HERE THE PAST FEW SEASONS               
 GIVEN THE WARM TEMPERATURES.                                                   
 THE FORECAST DETAILS...WILL BE UPGRADING THE LES WATCH TO A WARNING            
 FOR BERRIEN...CASS...ST JOSEPH...AND ELKHART COUNTIES. THE REMAINDER           
 OF THE COUNTIES IN THE WATCH WILL BE UPGRADED TO AN ADVISORY. MAY              
 SEE A RATHER INTENSE BAND ACROSS PARTS OF LAPORTE...STARKE...                  
 MARSHALL...AND KOSCIUSKO COUNTIES...HOWEVER EXPECT THE BAND TO                 
 REMAIN TRANSIENT THROUGH THESE COUNTIES AND NOT STAY OVER ONE SPOT             
 LONG ENOUGH TO DROP WARNING CRITERIA. IF IT BECOMES APPARENT THAT              
 THE BAND WILL GO STATIONARY FOR SEVERAL HOURS OVER ONE OF THESE                
 COUNTIES THAN AN UPGRADE MAY BE NEEDED. EXPECT THE MAJOR SINGLE BAND           
 TO BREAK APART INTO MULTIPLE BANDS...WEAKEN...AND SPREAD EAST ON TUE           
 AFTERNOON AS FLOW BACKS AND SYNOPTIC SCALE SUBSIDENCE INCREASES.               
 STORM TOTALS OF 6 TO 12 INCHES ARE POSSIBLE IN SOME LOCATIONS IN THE           
 WARNING COUNTIES...WITH LOCAL AMOUNTS OF OVER A FOOT POSSIBLE WHERE            
 BANDS PERSIST THE LONGEST.

 RAINFALL ACROSS THE REGION. GIVEN DEEP LOW LEVEL MOISTURE FIELD AND            
 WEAK LOW LEVEL LIFT IN PLACE...WILL MENTION PATCHY DRIZZLE THROUGH             
 MID AFTERNOON FOR MOST AREAS...PATCHY FREEZING DRIZZLE IN AREAS                
 WHICH REMAIN BELOW FREEZING. BY LATER THIS AFTERNOON...EXPANSIVE

 OTHERWISE MAIN CONCERN IS LAKE EFFECT SNOW POTENTIAL. STILL LOOKING            
 LIKE A SIGNIFICANT EVENT TONIGHT INTO TUE. WILL PERUSE FULL 12Z                
 MODEL SUITE BEFORE MAKING ANY CHANGES...BUT AT EARLY GLANCE IT                 
 APPEARS WARNINGS WILL BE NEEDED FOR A PORTION OF THE WATCH AREA AS A

 ...SIGNIFICANT LAKE EFFECT SNOW POSSIBLE TONIGHT AND TUESDAY...                
 NUMEROUS ISSUES IN THE SHORT TERM BEGINNING WITH ONGOING HEADLINES             
 AND ENDING WITH HEAVY LAKE EFFECT SNOW POTENTIAL TONIGHT INTO                  
 TUESDAY.                                                                       
 AS WE HAVE BEEN SAYING FOR DAYS...SURFACE LOW IS TRACKING WELL                 
 NORTHWEST OF WHERE MODELS HAD BEEN INDICATING...CURRENTLY NEAR KBMG            
 IN SOUTH CENTRAL INDIANA AT 07Z. THIS IS FURTHER NORTH THAN EVEN THE           
 NAM-WRF BUT CLOSE TO RUC40. LATEST 3HR PRESSURE FALLS ARE CENTERED             
 ACROSS NORTHEAST INDIANA AND INTO NORTHWEST OHIO...INDICATING LOW              
 WILL CONTINUE TO TRACK NORTHEAST. SINCE WE HAVE BEEN EXPECTING                 
 THIS...CURRENT GRIDS ARE IN RELATIVELY GOOD SHAPE.                             
 SURFACE TEMPERATURES HOVERING NEAR 30 ACROSS FAR NORTH WHERE WARNING           
 IS IN PLACE...RIGHT AROUND 32 IN ADVISORY AREA...AND 33 TO 35 IN               
 SOUTH WITH MODERATE TO HEAVY RAIN. EXPECT TEMPS TO RISE MAYBE A                
 DEGREE IN THE NORTH THIS MORNING BUT SEVERAL DEGREES IN THE                    
 SOUTHEAST AS SURFACE LOW TRACKS TO NEAR KAOH AND WARM AIR SURGES               
 NORTH. RUC40 HAS A GOOD HANDLE ON SURFACE LOW AND TEMPS SO USED THIS           
 ALONG WITH ETA12 FOR TEMPS TODAY. PLAN ON LEAVING HEADLINES AS IS              
 WITH INITIAL ISSUANCE GIVEN WIDESPREAD RAIN AND FREEZING RAIN STILL            
 ACROSS ENTIRE AREA. EXPECT PCPN TO DIMINISH IN WEST SHORTLY WITH               
 DECREASING TREND ACROSS CWA THIS MORNING. COLDER AIR ALREADY MAKING            
 A MOVE WITH SURFACE OBS IN WESTERN MICHIGAN SHOWING FALLING TEMPS              
 AND NORTH WINDS. EXPECT RESIDUAL DRIZZLE OR FREEZING DRIZZLE LATER             
 IN THE MORNING THEN LIGHT SNOW OR FLURRIES THIS AFTERNOON. NOT GOING           
 TO GET THAT DETAILED WITH GRIDS. WILL TRANSITION FROM CURRENT RAIN             
 TO LIGHT SNOW CHANCES THIS AFTERNOON. HAVE ISSUED SEVERAL FLOOD                
 WARNINGS FOR RIVERS EARLY THIS MORNING. WILL HOLD ONTO FLOOD WATCH             
 UNTIL RAIN ENDS.                                                               
 FOCUS THEN SHIFTS TO LAKE EFFECT POTENTIAL TONIGHT AND INTO TUESDAY.           
 AS SURFACE LOW MOVES EAST...ARCTIC AIR PLUNGES INTO FORECAST AREA              
 WITH 850MB TEMPS DROPPING TO -12 TO -14C TONIGHT AND TO NEAR -16C ON           
 TUESDAY. THIS COUPLED WITH WARM LAKE TEMPERATURES AROUND 5C YIELDS             
 DELTA T VALUES AROUND 20C. THIS EXTREME INSTABILITY WILL BE COUPLED            
 WITH HIGH LAKE INDUCED EQUILIBRIUM LEVELS AROUND 10K FEET AND LAKE             
 INDUCED CAPE NEARING 600 J/KG TUE MORNING. SYNOPTIC SETUP REMAINS              
 FAVORABLE WITH SURFACE LOW TO THE EAST AND ARCTIC HIGH IN THE PLAINS           
 CREATING A NEARLY NORTHERLY CYCLONIC FETCH DOWN LENGTH OF LAKE                 
 MICHIGAN. THIS USUALLY ALLOWS PRECONDITIONING FROM LAKE SUPERIOR AS            
 WELL. NAM-WRF AND EVEN GFS CONTINUE TO PICK UP ON THESE FEATURES AND           
 GENERATE STRONG 925-850MB OMEGA FROM 00Z TUE THROUGH 18Z TUE. THE              
 NEGATIVE FACTOR REMAINS THE WIND SHEAR NEAR THE TOP OF THE MIXED               
 LAYER...AS NOTED BY PREVIOUS DAY SHIFT. 700MB WIND COMPONENT STILL             
 REMAINS MORE WESTERLY THAN LOWER LEVELS. ALSO A BIT CONCERNED FOR              
 UPSTREAM SHORT WAVE THAT DROPS SOUTH LATE TONIGHT. THESE WAVES HAVE            
 BEEN KNOWN TO DISRUPT BANDS AND LIMIT HEAVY ACCUMULATIONS. AFTER               
 WEIGHING ALL THE PROS AND CONS...FEEL ENOUGH ELEMENTS IN PLACE TO              
 WARRANT A LAKE EFFECT SNOW WATCH FOR TONIGHT AND TUESDAY. GIVEN THE            
 NAM-WRF PLUME ANALYSIS SHOWING POTENTIAL WAVY BAND AND TO ACCOUNT              
 FOR MODELS WESTWARD BIAS...HAVE MADE THE WATCH AREA FAIRLY                     
 LARGE...ENCOMPASSING WESTERN AREAS FOR POTENTIAL SINGLE BAND DOWN              
 THE LENGTH OF LAKE...BUT ALSO ADDING CASS...ELKHART AND KOSCIUSKO              
 GIVEN PLUME ANALYSIS OF 925-850MB OMEGA FIELDS AND MODEL BIAS. WILL            
 HIT POTENTIAL FOR 6 TO 10 INCHES WITH THIS EVENT GIVEN THE MOVEMENT            
 OF SINGLE BAND. HOWEVER...IF THIS TYPE I BAND IS REALIZED AND                  
 BECOMES STATIONARY FOR A PERIOD OF TIME...LOCALLY HEAVIER AMOUNTS              
 WILL BE POSSIBLE.

 TUESDAY NIGHT THROUGH SUNDAY...LAKE EFFECT SNOW SHOULD BE                      
 DIMINISHING TUESDAY NIGHT AS INVERSION HEIGHTS FALL AND AS WINDS               
 BACK TO THE WEST AND SOUTHWEST. THE GFS CONTINUES TO RETREAT ON THE            
 VERY COLD AIR ADVERTISED DURING THE MIDDLE OF THE WEEK ON SEVERAL              
 PREVIOUS RUNS. HIGHS WEDNESDAY WERE IN THE LOWER 20S ON PREVIOUS MEX           
 MOS...BUT NOW IN THE MID 30S. CAN NOT SEEM TO GET ANY COLD IN HERE             
 AS THE LAST DAY BELOW NORMAL WAS DECEMBER 9. NEXT UPPER TROF WILL              
 DROP RAPIDLY SOUTH LATE THIS WEEK OVER THE WEST CONUS AS THE                   
 DOWNSTREAM TROF OVER THE MIDWEST MOVES RAPIDLY EAST. HAVE RAISED               
 HIGH AND LOWS TEMPS SOME TO ACCOMMODATE THIS PATTERN. THE NEXT                 
 CHANCE FOR PRECIPITATION WILL ARRIVE LATE IN THE WEEK AS THIS NEXT             
 SYSTEM MOVES EAST INTO THE FORECAST AREA. THE GFS AND ECMWF WERE               
 BRINGING COLDER AIR IN FRIDAY...WITH 850 MB TEMP DROPPING TO -20C BY           
 LATE IN THE DAY. LAKE EFFECT SNOW IN ONGOING GRIDS/ZFP LOOKS GOOD.             
 ONCE AGAIN...THIS TROF SHOULD LIFT EAST AS ANOTHER DEEP TROF DIGS              
 OVER THE WESTERN CONUS. THE ECMWF WAS EVEN INDICATING SOME NEGATIVE            
 TILT WITH THIS TROF...BUT THE MAIN WEATHER INDICATION FOR THE                  
 FORECAST AREA WILL BE LAKE EFFECT ENDING LATE SATURDAY WITH                    
 TEMPERATURES RETURNING TO NORMAL BY SUNDAY. NEW CANADIAN ENSEMBLE              
 MEMBERS SUPPORT THIS PATTERN WITH A BROAD TROF OVER THE CENTRAL                
 UNITED STATES.

 CHANCE FOR PRECIPITATION WILL ARRIVE LATE IN THE WEEK AS THIS NEXT

 BRINGING COLDER AIR IN FRIDAY...WITH 850 MB TEMP DROPPING TO -20C BY           
 LATE IN THE DAY. LAKE EFFECT SNOW IN ONGOING GRIDS/ZFP LOOKS GOOD.

 LATE IN THE DAY. LAKE EFFECT SNOW IN ONGOING GRIDS/ZFP LOOKS GOOD. ONCE        
 AGAIN...THIS TROF SHOULD LIFT EAST AS ANOTHER DEEP TROF DIGS OVER              
 THE WESTERN CONUS. THE ECMWF WAS EVEN INDICATING SOME NEGATIVE TILT            
 WITH THIS TROF...BUT THE MAIN WEATHER INDICATION FOR THE FORECAST

 BASED ON THE TREND OF BRINGING THE LOW FARTHER NORTHWEST...FEEL MORE           
 INCLINED TO SIDE WITH THE NAM-WRF AND THUS WILL USE ITS SOLUTION AS            
 A BACKBONE TO THE SHORT TERM FORECAST.  ITS WARMER THERMAL PROFILE             
 WILL RESULT IN MOSTLY FREEZING RAIN TONIGHT ACRS THE NRN CWFA.                 
 AT 20Z...LOW PRESSURE WAS DEVELOPING ALONG A STATIONARY FRONT OVER             
 NW ARKANSAS.  AS A STRONG S/WV AND JET PIVOT NORTHEAST INTO THE

 LOCATED NEAR SW INDIANA AT 06Z MONDAY AND NEAR NW OHIO BY 12Z MONDAY.          
 THE LOW WILL BE ASSOCIATED WITH STRONG...MOIST LOW LVL WARM                    
 ADVECTION.  THIS STRONG ASCENT WILL TEAM UP WITH UPR LVL DIVERGENCE            
 FROM A STRONG JET ALOFT.  THIS WILL RESULT IN WIDESPREAD PCPN ACRS             
 THE CWFA OVERNIGHT.  IN FACT...LATEST MOSAIC RADAR WAS SHOWING A               
 LARGE AREA OF PCPN BLOSSOMING ACRS THE CNTRL AND SRN PLAINS.  THIS

 THERE IS A LOT TO BE CONCERNED ABOUT OVERNIGHT INTO THE FIRST PART             
 OF MONDAY AS COLD AIR REMAINS TRAPPED NEAR THE SFC ACRS THE FAR NRN

 DEGREES ACRS FAR NRN INDIANA...SOUTHERN LOWER MICHIGAN AND FAR                 
 NORTHWEST OHIO.  THESE TEMPS WILL NOT BUDGE MUCH OVERNIGHT...AND MAY           
 SLIGHTLY DROP A DEGREE OR TWO.  FOR THE REMAINDER OF THE                       
 REGION...TEMPS WILL REMAIN STEADY STATE IN THE LOWER TO MID

 AROUND ONE INCH OF QPF EXPECTED OVERNIGHT...SIGNIFICANT ICING WILL             
 OCCUR ACRS THE MICHIGAN COUNTIES WHERE ABOUT A HALF INCH OF ICE                
 ACCUMULATION IS EXPECTED.  FOR THE FAR NRN INDIANA AND NORTHWEST               
 OHIO COUNTIES...ICE ACCUMULATIONS WILL BE LESS THAN A QUARTER INCH.            
 FARTHER SOUTH...MAINLY RAIN IS EXPECTED.  AN ICE STORM WARNING WILL            
 BE ISSUED FOR THE MICHIGAN COUNTIES UNTIL 17Z MONDAY...WHILE A                 
 FREEZING RAIN ADVISORY WILL BE ISSUED FOR THE FAR NRN INDIANA/NW               
 OHIO COUNTIES THROUGH 17Z MONDAY. ADDITIONAL RAINFALL ACRS THE FAR             
 SOUTH/SOUTHEAST WILL LIKELY LEAD TO RIVER FLOODING ALONG THE UPPER             
 WABASH AND MAUMEE RIVER BASINS..SO WILL MAINTAIN FLOOD WATCH FOR               
 THIS LOCATION THROUGH 18Z MONDAY.                                              
 ON MONDAY...AS SFC LOW PRESSURE PULLS AWAY TO THE NE...COLDER AIR

 FREEZING PCPN ACRS THE NW HALF OF THE CWFA...BUT THIS SHOULD BE ON             
 THE LIGHT SIDE.  FOR THE SOUTHEAST...LIGHT RAIN IS EXPECTED.  MODELS           
 CONTINUE TO SHOW A DRY SLOT WORKING INTO THE REGION BY MID MORNING.            
 THIS MAY CHC PCPN TO DRIZZLE OR FREEZING DRIZZLE.  HAVE OPTED TO GO            
 WITH THE LIGHT FREEZING RAIN/LIGHT RAIN WORDING DUE TO LINGER PCPN             
 EARLY IN THE MORNING IN ASSOCIATION WITH THE LOW AND FOR THE FACT              
 THAT SOME OF THE DRIZZLE MAY MEASURE.  AS COLDER AIR AND DEEPER                
 ATMOSPHERIC MOISTURE FILTER INTO THE REGION DURING THE                         
 AFTERNOON...ANY DRIZZLE WILL CHANGEOVER TO SOME LIGHT SNOW.  MAIN              
 LAKE EFFECT EVENT LOOKS TO HOLD OFF UNTIL MONDAY NIGHT AND WILL                
 LEAVE THOSE DETAILS TO THE LONG TERM FORECASTER.

 MAIN CONCERN FOR THE LONG TERM TODAY REVOLVES AROUND LAKE EFFECT               
 POTENTIAL AT THE START OF THE PERIOD. MODERATE LOW/MID LEVEL CAA               
 FOLLOWING MAJOR FRONTAL WAVE ON MON WILL BRING MUCH COLDER AIR                 
 ACROSS THE LAKE WITH AMPLE LAKE INSTABILITY DEVELOPING. NEAR RECORD            
 WARM LAKE TEMPERATURE OF AROUND 5C PER LATEST SATELLITE DERIVED DATA           
 WILL CONTRIBUTE TO MODERATE COLLIER INDEX WITH LAKE INDUCED CAPE               
 AROUND 500J/KG AND LAKE INDUCED EQUILIBRIUM LEVELS AROUND 10K FEET.            
 INSTABILITY IS CERTAINLY MORE THAN AMPLE...HOWEVER MUCH UNCERTAINTY            
 LIES WITH BAND MODE...PLACEMENT...AND AMOUNT OF SHEAR. FROM A                  
 PATTERN RECOGNITION PROSPECTIVE...SETUP LOOKS VERY FAVORABLE WITH A            
 1040+MB HIGH BUILDING SOUTH THROUGH THE PLAINS AND FAVORABLE N/NNW             
 FLOW DEVELOPING DOWN A SUBSTANTIAL FETCH OF LAKE MICHIGAN. A                   
 POTENTIAL NEGATIVE...BOTH NAM/GFS SUGGEST THERE WILL BE SOME SHEAR             
 NEAR THE TOP OF THE LAKE INDUCED MIXED LAYER WITH A MORE WESTERLY              
 COMPONENT AT 700MB AND MORE NW/NNW AT 850MB. NAM-WRF PLUME ANALYSIS            
 CONTINUES TO SUGGEST THE POTENTIAL FOR A TYPE I LAKE EFFECT                    
 BAND...MEANING A DOMINANT BAND PARALLEL TO THE MAJOR AXIS OF THE               
 LAKE.                                                                          
 NAM-WRF HAS BEEN FLIP-FLOPPING WILDLY FROM RUN TO RUN WITH RESPECT             
 TO DIRECTION OF LOW LEVEL FLOW...WITH 00Z AND 06Z RUNS SUGGESTING A

 THE FWA AREA. CIGS/VSBYS WERE ALREADY LOWERING IN ADVANCE OF THE               
 RAINFALL THIS EVE APPARENTLY IN RESPONSE TO DIURNAL COOLING OF THE             
 VERY MOIST LOW LEVELS. TEMPS EXPECTED TO REMAIN JUST COLD ENOUGH FOR           
 FREEZING RAIN AT SBN AND JUST WARM ENOUGH FOR RAIN NOT TO FREEZE AT            
 FWA AS THE LOW MOVES NE ACROSS SRN INDIANA TONIGHT. PRECIP INTENSITY           
 SHOULD DIMINISH ON MONDAY AS MID LEVEL DRY SLOT MOVES OVER THE AREA.           
 WITH COLD AIR WRAPPING AROUND THE LOW AS IT DEPARTS THE AREA TO OUR            
 EAST ON MONDAY, PRECIP SHOULD CHANGE OVER TO SNOW AT SBN EARLY IN              
 THE AFTN. POTENTIAL FOR LAKE ENHANCEMENT TO INTENSIFY SNOWFALL LATE            
 AFTN BUT SINCE NEAR END OF TAF PD DID NOT ADD TO TAFS YET. LIKEWISE

 FARTHER NORTHWEST.  THE NAM-WRF IS THE FARTHEST NORTHWEST OF THE               
 TWO...PLACING THE WAVE OF LOW PRESSURE OVER NW OHIO BY 12Z MONDAY.             
 BASED ON THE TREND OF BRINGING THE LOW FARTHER NORTHWEST...FEEL MORE           
 INCLINED TO SIDE WITH THE NAM-WRF AND THUS WILL USE ITS SOLUTION AS            
 A BACKBONE TO THE SHORT TERM FORECAST.  ITS WARMER THERMAL PROFILE             
 WILL RESULT IN MOSTLY FREEZING RAIN TONIGHT ACRS THE NRN CWFA.                 
 AT 20Z...LOW PRESSURE WAS DEVELOPING ALONG A STATIONARY FRONT OVER             
 NW ARKANSAS.  AS A STRONG S/WV AND JET PIVOT NORTHEAST INTO THE

 LOCATED NEAR SW INDIANA AT 06Z MONDAY AND NEAR NW OHIO BY 12Z MONDAY.          
 THE LOW WILL BE ASSOCIATED WITH STRONG...MOIST LOW LVL WARM                    
 ADVECTION.  THIS STRONG ASCENT WILL TEAM UP WITH UPR LVL DIVERGENCE            
 FROM A STRONG JET ALOFT.  THIS WILL RESULT IN WIDESPREAD PCPN ACRS             
 THE CWFA OVERNIGHT.  IN FACT...LATEST MOSAIC RADAR WAS SHOWING A               
 LARGE AREA OF PCPN BLOSSOMING ACRS THE CNTRL AND SRN PLAINS.  THIS             
 PCPN WILL CONTINUE TO EXPAND AND MOVE NE INTO THE REGION TONIGHT.              
 THERE IS A LOT TO BE CONCERNED ABOUT OVERNIGHT INTO THE FIRST PART             
 OF MONDAY AS COLD AIR REMAINS TRAPPED NEAR THE SFC ACRS THE FAR NRN

 DEGREES ACRS FAR NRN INDIANA...SOUTHERN LOWER MICHIGAN AND FAR                 
 NORTHWEST OHIO.  THESE TEMPS WILL NOT BUDGE MUCH OVERNIGHT...AND MAY           
 SLIGHTLY DROP A DEGREE OR TWO.  FOR THE REMAINDER OF THE                       
 REGION...TEMPS WILL REMAIN STEADY STATE IN THE LOWER TO MID                    
 30S...EXPECT FOR THE FAR SOUTHEAST WHERE WARMER AIR WILL BE PULLED             
 WESTWARD AS THE LOW APPROACHES.   WITH ABOUT THREE QUARTERS TO                 
 AROUND ONE INCH OF QPF EXPECTED OVERNIGHT...SIGNIFICANT ICING WILL             
 OCCUR ACRS THE MICHIGAN COUNTIES WHERE ABOUT A HALF INCH OF ICE                
 ACCUMULATION IS EXPECTED.  FOR THE FAR NRN INDIANA AND NORTHWEST

 OHIO COUNTIES THROUGH 17Z MONDAY. ADDITIONAL RAINFALL ACRS THE FAR             
 SOUTH/SOUTHEAST WILL LIKELY LEAD TO RIVER FLOODING ALONG THE UPPER             
 WABASH AND MAUMEE RIVER BASINS..SO WILL MAINTAIN FLOOD WATCH FOR               
 THIS LOCATION THROUGH 18Z MONDAY.                                              
 ON MONDAY...AS SFC LOW PRESSURE PULLS AWAY TO THE NE...COLDER AIR

 THIS MAY CHC PCPN TO DRIZZLE OR FREEZING DRIZZLE.  HAVE OPTED TO GO            
 WITH THE LIGHT FREEZING RAIN/LIGHT RAIN WORDING DUE TO LINGER PCPN             
 EARLY IN THE MORNING IN ASSOCIATION WITH THE LOW AND FOR THE FACT              
 THAT SOME OF THE DRIZZLE MAY MEASURE.  AS COLDER AIR AND DEEPER                
 ATMOSPHERIC MOISTURE FILTER INTO THE REGION DURING THE

 MAIN CONCERN FOR THE LONG TERM TODAY REVOLVES AROUND LAKE EFFECT               
 POTENTIAL AT THE START OF THE PERIOD. MODERATE LOW/MID LEVEL CAA               
 FOLLOWING MAJOR FRONTAL WAVE ON MON WILL BRING MUCH COLDER AIR                 
 ACROSS THE LAKE WITH AMPLE LAKE INSTABILITY DEVELOPING. NEAR RECORD            
 WARM LAKE TEMPERATURE OF AROUND 5C PER LATEST SATELLITE DERIVED DATA           
 WILL CONTRIBUTE TO MODERATE COLLIER INDEX WITH LAKE INDUCED CAPE               
 AROUND 500J/KG AND LAKE INDUCED EQUILIBRIUM LEVELS AROUND 10K FEET.            
 INSTABILITY IS CERTAINLY MORE THAN AMPLE...HOWEVER MUCH UNCERTAINTY            
 LIES WITH BAND MODE...PLACEMENT...AND AMOUNT OF SHEAR. FROM A                  
 PATTERN RECOGNITION PROSPECTIVE...SETUP LOOKS VERY FAVORABLE WITH A            
 1040+MB HIGH BUILDING SOUTH THROUGH THE PLAINS AND FAVORABLE N/NNW             
 FLOW DEVELOPING DOWN A SUBSTANTIAL FETCH OF LAKE MICHIGAN. A                   
 POTENTIAL NEGATIVE...BOTH NAM/GFS SUGGEST THERE WILL BE SOME SHEAR             
 NEAR THE TOP OF THE LAKE INDUCED MIXED LAYER WITH A MORE WESTERLY              
 COMPONENT AT 700MB AND MORE NW/NNW AT 850MB. NAM-WRF PLUME ANALYSIS            
 CONTINUES TO SUGGEST THE POTENTIAL FOR A TYPE I LAKE EFFECT                    
 BAND...MEANING A DOMINANT BAND PARALLEL TO THE MAJOR AXIS OF THE               
 LAKE.                                                                          
 NAM-WRF HAS BEEN FLIP-FLOPPING WILDLY FROM RUN TO RUN WITH RESPECT             
 TO DIRECTION OF LOW LEVEL FLOW...WITH 00Z AND 06Z RUNS SUGGESTING A            
 NEAR DUE NORTH FETCH...WHILE 12Z RUN SUGGESTS MORE NW FETCH. A LOOK            
 AT SOME OTHER MESOSCALE GUIDANCE SUCH AS THE FSL EXPERIMENTAL RUC              
 AND THE CANADIAN GEM SHOW MORE UNCERTAINTY...WITH BOTH THOSE MODELS            
 DEPICTING MORE NORTHERLY FLOW AND A MORE WESTWARD BAND PLACEMENT.              
 TYPICAL BIAS OF MESOSCALE MODELS ARE TO BE TOO FAR WEST WITH A                 
 DOMINANT BAND AT THE SOUTHERN END OF LAKE MICHIGAN. WITH THE VERY              
 POOR MODEL AGREEMENT AND CONSISTENCY...JUST NOT ENOUGH CONFIDENCE              
 ON BAND PLACEMENT OR MODE TO GO WITH AN LES WATCH YET. STILL ENOUGH            
 TIME FOR A SHORTER RANGE WATCH FROM THE MIDNIGHT SHIFT IF MODEL                
 GUIDANCE STARTS TO CONVERGE ON A COMMON SOLUTION. THIS DOES HAVE THE           
 POTENTIAL TO BE A MAJOR EVENT GIVEN STRONG THERMODYNAMICS...BUT ONLY           
 IF A DOMINANT BAND FORMS...AND THAT IS STILL QUITE UNCERTAIN.

 PATCHY REPORTS OF GLAZING IN NRN INDIANA AND NW OH EVEN THOUGH SOME            
 ASOS/AWOS SITES REPORTING TEMPS AT FREEZING. THIS PRBLY A RESULT OF

 FREEZING. IN MICHIGAN WHERE SFC TEMPS HAVE BEEN RUNNING A DEGREE OR            
 TWO BELOW FREEZING ALL DAY AND THIS EVE, MORE WIDESPREAD GLAZING IS            
 BEING REPORTED. WITH WAA OVERNIGHT AS SFC LOW MOVES NE FROM SRN MO             
 TO WEST CENTRAL OH, THE RN/SN LINE, WHICH IS EXPECTED TO SETUP FROM            
 JUST NORTH OF CHICAGO TO JUST NORTH OF DETROIT THIS EVE, WILL PRBLY

 MAINLY LIQUID EVENT WITH MAIN THREAT FOR ICE ACCUMULATIONS ACROSS

 ACCUMULATE AS ICE IN THE ADVISORY AREAS AND IF SFC TEMPS WILL FALL             
 SUFFICIENTLY SOUTH OF THE ADVISORY AREA TO WARRANT EXPANSION. FOR

 SWRN MO THIS EVE WAS CAUSING OVER-RUNNING PRECIP TO DVLP NORTH OF

 THE NEXT COUPLE OF HOURS WITH HEAVIEST RAINFALL INITIALLY MOVG INTO            
 THE FWA AREA. CIGS/VSBYS WERE ALREADY LOWERING IN ADVANCE OF THE               
 RAINFALL THIS EVE APPARENTLY IN RESPONSE TO DIURNAL COOLING OF THE             
 VERY MOIST LOW LEVELS. TEMPS EXPECTED TO REMAIN JUST COLD ENOUGH FOR           
 FREEZING RAIN AT SBN AND JUST WARM ENOUGH FOR RAIN NOT TO FREEZE AT            
 FWA AS THE LOW MOVES NE ACROSS SRN INDIANA TONIGHT. PRECIP INTENSITY           
 SHOULD DIMINISH ON MONDAY AS MID LEVEL DRY SLOT MOVES OVER THE AREA.           
 WITH COLD AIR WRAPPING AROUND THE LOW AS IT DEPARTS THE AREA TO OUR            
 EAST ON MONDAY, PRECIP SHOULD CHANGE OVER TO SNOW AT SBN EARLY IN              
 THE AFTN. POTENTIAL FOR LAKE ENHANCEMENT TO INTENSIFY SNOWFALL LATE            
 AFTN BUT SINCE NEAR END OF TAF PD DID NOT ADD TO TAFS YET. LIKEWISE

 FARTHER NORTHWEST.  THE NAM-WRF IS THE FARTHEST NORTHWEST OF THE               
 TWO...PLACING THE WAVE OF LOW PRESSURE OVER NW OHIO BY 12Z MONDAY.             
 BASED ON THE TREND OF BRINGING THE LOW FARTHER NORTHWEST...FEEL MORE           
 INCLINED TO SIDE WITH THE NAM-WRF AND THUS WILL USE ITS SOLUTION AS            
 A BACKBONE TO THE SHORT TERM FORECAST.  ITS WARMER THERMAL PROFILE             
 WILL RESULT IN MOSTLY FREEZING RAIN TONIGHT ACRS THE NRN CWFA.                 
 AT 20Z...LOW PRESSURE WAS DEVELOPING ALONG A STATIONARY FRONT OVER             
 NW ARKANSAS.  AS A STRONG S/WV AND JET PIVOT NORTHEAST INTO THE                
 CNTRL PLAINS TONIGHT AND THEN INTO THE WRN GREAT LAKES ON                      
 MONDAY...THE LOW WILL MOVE NORTHEAST AND DEEPEN WITH TIME...BEING              
 LOCATED NEAR SW INDIANA AT 06Z MONDAY AND NEAR NW OHIO BY 12Z MONDAY.          
 THE LOW WILL BE ASSOCIATED WITH STRONG...MOIST LOW LVL WARM                    
 ADVECTION.  THIS STRONG ASCENT WILL TEAM UP WITH UPR LVL DIVERGENCE            
 FROM A STRONG JET ALOFT.  THIS WILL RESULT IN WIDESPREAD PCPN ACRS             
 THE CWFA OVERNIGHT.  IN FACT...LATEST MOSAIC RADAR WAS SHOWING A               
 LARGE AREA OF PCPN BLOSSOMING ACRS THE CNTRL AND SRN PLAINS.  THIS             
 PCPN WILL CONTINUE TO EXPAND AND MOVE NE INTO THE REGION TONIGHT.              
 THERE IS A LOT TO BE CONCERNED ABOUT OVERNIGHT INTO THE FIRST PART             
 OF MONDAY AS COLD AIR REMAINS TRAPPED NEAR THE SFC ACRS THE FAR NRN            
 CWFA.  LATEST OBSERVATIONS SHOW TEMPS HOVERING BETWEEN 30 AND 33               
 DEGREES ACRS FAR NRN INDIANA...SOUTHERN LOWER MICHIGAN AND FAR                 
 NORTHWEST OHIO.  THESE TEMPS WILL NOT BUDGE MUCH OVERNIGHT...AND MAY           
 SLIGHTLY DROP A DEGREE OR TWO.  FOR THE REMAINDER OF THE                       
 REGION...TEMPS WILL REMAIN STEADY STATE IN THE LOWER TO MID                    
 30S...EXPECT FOR THE FAR SOUTHEAST WHERE WARMER AIR WILL BE PULLED             
 WESTWARD AS THE LOW APPROACHES.   WITH ABOUT THREE QUARTERS TO                 
 AROUND ONE INCH OF QPF EXPECTED OVERNIGHT...SIGNIFICANT ICING WILL             
 OCCUR ACRS THE MICHIGAN COUNTIES WHERE ABOUT A HALF INCH OF ICE                
 ACCUMULATION IS EXPECTED.  FOR THE FAR NRN INDIANA AND NORTHWEST               
 OHIO COUNTIES...ICE ACCUMULATIONS WILL BE LESS THAN A QUARTER INCH.            
 FARTHER SOUTH...MAINLY RAIN IS EXPECTED.  AN ICE STORM WARNING WILL            
 BE ISSUED FOR THE MICHIGAN COUNTIES UNTIL 17Z MONDAY...WHILE A                 
 FREEZING RAIN ADVISORY WILL BE ISSUED FOR THE FAR NRN INDIANA/NW               
 OHIO COUNTIES THROUGH 17Z MONDAY. ADDITIONAL RAINFALL ACRS THE FAR             
 SOUTH/SOUTHEAST WILL LIKELY LEAD TO RIVER FLOODING ALONG THE UPPER             
 WABASH AND MAUMEE RIVER BASINS..SO WILL MAINTAIN FLOOD WATCH FOR               
 THIS LOCATION THROUGH 18Z MONDAY.                                              
 ON MONDAY...AS SFC LOW PRESSURE PULLS AWAY TO THE NE...COLDER AIR

 THE LIGHT SIDE.  FOR THE SOUTHEAST...LIGHT RAIN IS EXPECTED.  MODELS           
 CONTINUE TO SHOW A DRY SLOT WORKING INTO THE REGION BY MID MORNING.            
 THIS MAY CHC PCPN TO DRIZZLE OR FREEZING DRIZZLE.  HAVE OPTED TO GO            
 WITH THE LIGHT FREEZING RAIN/LIGHT RAIN WORDING DUE TO LINGER PCPN             
 EARLY IN THE MORNING IN ASSOCIATION WITH THE LOW AND FOR THE FACT              
 THAT SOME OF THE DRIZZLE MAY MEASURE.  AS COLDER AIR AND DEEPER                
 ATMOSPHERIC MOISTURE FILTER INTO THE REGION DURING THE                         
 AFTERNOON...ANY DRIZZLE WILL CHANGEOVER TO SOME LIGHT SNOW.  MAIN

 MAIN CONCERN FOR THE LONG TERM TODAY REVOLVES AROUND LAKE EFFECT               
 POTENTIAL AT THE START OF THE PERIOD. MODERATE LOW/MID LEVEL CAA               
 FOLLOWING MAJOR FRONTAL WAVE ON MON WILL BRING MUCH COLDER AIR                 
 ACROSS THE LAKE WITH AMPLE LAKE INSTABILITY DEVELOPING. NEAR RECORD            
 WARM LAKE TEMPERATURE OF AROUND 5C PER LATEST SATELLITE DERIVED DATA           
 WILL CONTRIBUTE TO MODERATE COLLIER INDEX WITH LAKE INDUCED CAPE               
 AROUND 500J/KG AND LAKE INDUCED EQUILIBRIUM LEVELS AROUND 10K FEET.            
 INSTABILITY IS CERTAINLY MORE THAN AMPLE...HOWEVER MUCH UNCERTAINTY            
 LIES WITH BAND MODE...PLACEMENT...AND AMOUNT OF SHEAR. FROM A                  
 PATTERN RECOGNITION PROSPECTIVE...SETUP LOOKS VERY FAVORABLE WITH A            
 1040+MB HIGH BUILDING SOUTH THROUGH THE PLAINS AND FAVORABLE N/NNW             
 FLOW DEVELOPING DOWN A SUBSTANTIAL FETCH OF LAKE MICHIGAN. A                   
 POTENTIAL NEGATIVE...BOTH NAM/GFS SUGGEST THERE WILL BE SOME SHEAR             
 NEAR THE TOP OF THE LAKE INDUCED MIXED LAYER WITH A MORE WESTERLY              
 COMPONENT AT 700MB AND MORE NW/NNW AT 850MB. NAM-WRF PLUME ANALYSIS            
 CONTINUES TO SUGGEST THE POTENTIAL FOR A TYPE I LAKE EFFECT                    
 BAND...MEANING A DOMINANT BAND PARALLEL TO THE MAJOR AXIS OF THE               
 LAKE.                                                                          
 NAM-WRF HAS BEEN FLIP-FLOPPING WILDLY FROM RUN TO RUN WITH RESPECT             
 TO DIRECTION OF LOW LEVEL FLOW...WITH 00Z AND 06Z RUNS SUGGESTING A            
 NEAR DUE NORTH FETCH...WHILE 12Z RUN SUGGESTS MORE NW FETCH. A LOOK            
 AT SOME OTHER MESOSCALE GUIDANCE SUCH AS THE FSL EXPERIMENTAL RUC              
 AND THE CANADIAN GEM SHOW MORE UNCERTAINTY...WITH BOTH THOSE MODELS            
 DEPICTING MORE NORTHERLY FLOW AND A MORE WESTWARD BAND PLACEMENT.              
 TYPICAL BIAS OF MESOSCALE MODELS ARE TO BE TOO FAR WEST WITH A                 
 DOMINANT BAND AT THE SOUTHERN END OF LAKE MICHIGAN. WITH THE VERY              
 POOR MODEL AGREEMENT AND CONSISTENCY...JUST NOT ENOUGH CONFIDENCE              
 ON BAND PLACEMENT OR MODE TO GO WITH AN LES WATCH YET. STILL ENOUGH            
 TIME FOR A SHORTER RANGE WATCH FROM THE MIDNIGHT SHIFT IF MODEL                
 GUIDANCE STARTS TO CONVERGE ON A COMMON SOLUTION. THIS DOES HAVE THE           
 POTENTIAL TO BE A MAJOR EVENT GIVEN STRONG THERMODYNAMICS...BUT ONLY           
 IF A DOMINANT BAND FORMS...AND THAT IS STILL QUITE UNCERTAIN.                  
 CP SURFACE HIGH BUILDS ACROSS THE OHIO VALLEY LATER TUE NGT INTO WED           
 WITH CRASHING INVERSION HEIGHTS AND BACKING LOW LEVEL FLOW CUTTING             
 OFF ANY REMAINING LAKE EFFECT. SHOULD SEE A DRY PERIOD FOR WED AND

 UPSTREAM TROUGH. VERY LITTLE CHANGE MADE TO CONTINUITY IN THE LATER

 THE NEXT COUPLE OF HOURS WITH HEAVIEST RAINFALL INITIALLY MOVG INTO            
 THE FWA AREA. CIGS/VSBYS WERE ALREADY LOWERING IN ADVANCE OF THE               
 RAINFALL THIS EVE APPARENTLY IN RESPONSE TO DIURNAL COOLING OF THE             
 VERY MOIST LOW LEVELS. TEMPS EXPECTED TO REMAIN JUST COLD ENOUGH FOR           
 FREEZING RAIN AT SBN AND JUST WARM ENOUGH FOR RAIN NOT TO FREEZE AT            
 FWA AS THE LOW MOVES NE ACROSS SRN INDIANA TONIGHT. PRECIP INTENSITY           
 SHOULD DIMINISH ON MONDAY AS MID LEVEL DRY SLOT MOVES OVER THE AREA.           
 WITH COLD AIR WRAPPING AROUND THE LOW AS IT DEPARTS THE AREA TO OUR

 AFTN BUT SINCE NEAR END OF TAF PD DID NOT ADD TO TAFS YET. LIKEWISE

 THIS MAY CHC PCPN TO DRIZZLE OR FREEZING DRIZZLE.  HAVE OPTED TO GO            
 WITH THE LIGHT FREEZING RAIN/LIGHT RAIN WORDING DUE TO LINGER PCPN

 MAIN CONCERN FOR THE LONG TERM TODAY REVOLVES AROUND LAKE EFFECT               
 POTENTIAL AT THE START OF THE PERIOD. MODERATE LOW/MID LEVEL CAA               
 FOLLOWING MAJOR FRONTAL WAVE ON MON WILL BRING MUCH COLDER AIR                 
 ACROSS THE LAKE WITH AMPLE LAKE INSTABILITY DEVELOPING. NEAR RECORD            
 WARM LAKE TEMPERATURE OF AROUND 5C PER LATEST SATELLITE DERIVED DATA           
 WILL CONTRIBUTE TO MODERATE COLLIER INDEX WITH LAKE INDUCED CAPE               
 AROUND 500J/KG AND LAKE INDUCED EQUILIBRIUM LEVELS AROUND 10K FEET.            
 INSTABILITY IS CERTAINLY MORE THAN AMPLE...HOWEVER MUCH UNCERTAINTY            
 LIES WITH BAND MODE...PLACEMENT...AND AMOUNT OF SHEAR. FROM A                  
 PATTERN RECOGNITION PROSPECTIVE...SETUP LOOKS VERY FAVORABLE WITH A            
 1040+MB HIGH BUILDING SOUTH THROUGH THE PLAINS AND FAVORABLE N/NNW             
 FLOW DEVELOPING DOWN A SUBSTANTIAL FETCH OF LAKE MICHIGAN. A                   
 POTENTIAL NEGATIVE...BOTH NAM/GFS SUGGEST THERE WILL BE SOME SHEAR             
 NEAR THE TOP OF THE LAKE INDUCED MIXED LAYER WITH A MORE WESTERLY              
 COMPONENT AT 700MB AND MORE NW/NNW AT 850MB. NAM-WRF PLUME ANALYSIS            
 CONTINUES TO SUGGEST THE POTENTIAL FOR A TYPE I LAKE EFFECT                    
 BAND...MEANING A DOMINANT BAND PARALLEL TO THE MAJOR AXIS OF THE               
 LAKE.                                                                          
 NAM-WRF HAS BEEN FLIP-FLOPPING WILDLY FROM RUN TO RUN WITH RESPECT             
 TO DIRECTION OF LOW LEVEL FLOW...WITH 00Z AND 06Z RUNS SUGGESTING A            
 NEAR DUE NORTH FETCH...WHILE 12Z RUN SUGGESTS MORE NW FETCH. A LOOK            
 AT SOME OTHER MESOSCALE GUIDANCE SUCH AS THE FSL EXPERIMENTAL RUC              
 AND THE CANADIAN GEM SHOW MORE UNCERTAINTY...WITH BOTH THOSE MODELS            
 DEPICTING MORE NORTHERLY FLOW AND A MORE WESTWARD BAND PLACEMENT.              
 TYPICAL BIAS OF MESOSCALE MODELS ARE TO BE TOO FAR WEST WITH A                 
 DOMINANT BAND AT THE SOUTHERN END OF LAKE MICHIGAN. WITH THE VERY              
 POOR MODEL AGREEMENT AND CONSISTENCY...JUST NOT ENOUGH CONFIDENCE              
 ON BAND PLACEMENT OR MODE TO GO WITH AN LES WATCH YET. STILL ENOUGH            
 TIME FOR A SHORTER RANGE WATCH FROM THE MIDNIGHT SHIFT IF MODEL                
 GUIDANCE STARTS TO CONVERGE ON A COMMON SOLUTION. THIS DOES HAVE THE           
 POTENTIAL TO BE A MAJOR EVENT GIVEN STRONG THERMODYNAMICS...BUT ONLY           
 IF A DOMINANT BAND FORMS...AND THAT IS STILL QUITE UNCERTAIN.                  
 CP SURFACE HIGH BUILDS ACROSS THE OHIO VALLEY LATER TUE NGT INTO WED           
 WITH CRASHING INVERSION HEIGHTS AND BACKING LOW LEVEL FLOW CUTTING             
 OFF ANY REMAINING LAKE EFFECT. SHOULD SEE A DRY PERIOD FOR WED AND             
 THU WITH A MODERATING TREND AS HEIGHTS RISE IN RESPONSE TO DIGGING             
 UPSTREAM TROUGH. VERY LITTLE CHANGE MADE TO CONTINUITY IN THE LATER            
 PERIODS WITH PRIMARY CONCERNS IN SHORT TERM HIGH IMPACT WEATHER.               
 STILL APPEARS THAT ONE OR SEVERAL CLIPPER TYPE SHORTWAVES WILL CROSS           
 THE GREAT LAKES STARTING AT THE END OF THE WEEK AND HAVE CONTINUED             
 WITH LOW CHANCE POPS...MAINLY ACROSS THE NORTHERN PORTION OF THE

 MAIN CONCERN FOR THE LONG TERM TODAY REVOLVES AROUND LAKE EFFECT               
 POTENTIAL AT THE START OF THE PERIOD. MODERATE LOW/MID LEVEL CAA               
 FOLLOWING MAJOR FRONTAL WAVE ON MON WILL BRING MUCH COLDER AIR                 
 ACROSS THE LAKE WITH AMPLE LAKE INSTABILITY DEVELOPING. NEAR RECORD            
 WARM LAKE TEMPERATURE OF AROUND 5C PER LATEST SATELLITE DERIVED DATA           
 WILL CONTRIBUTE TO MODERATE COLLIER INDEX WITH LAKE INDUCED CAPE               
 AROUND 500J/KG AND LAKE INDUCED EQUILIBRIUM LEVELS AROUND 10K FEET.            
 INSTABILITY IS CERTAINLY MORE THAN AMPLE...HOWEVER MUCH UNCERTAINTY            
 LIES WITH BAND MODE...PLACEMENT...AND AMOUNT OF SHEAR. FROM A                  
 PATTERN RECOGNITION PROSPECTIVE...SETUP LOOKS VERY FAVORABLE WITH A            
 1040+MB HIGH BUILDING SOUTH THROUGH THE PLAINS AND FAVORABLE N/NNW             
 FLOW DEVELOPING DOWN A SUBSTANTIAL FETCH OF LAKE MICHIGAN. A                   
 POTENTIAL NEGATIVE...BOTH NAM/GFS SUGGEST THERE WILL BE SOME SHEAR             
 NEAR THE TOP OF THE LAKE INDUCED MIXED LAYER WITH A MORE WESTERLY              
 COMPONENT AT 700MB AND MORE NW/NNW AT 850MB. NAM-WRF PLUME ANALYSIS            
 CONTINUES TO SUGGEST THE POTENTIAL FOR A TYPE I LAKE EFFECT                    
 BAND...MEANING A DOMINANT BAND PARALLEL TO THE MAJOR AXIS OF THE               
 LAKE.

 NEAR DUE NORTH FETCH...WHILE 12Z RUN SUGGESTS MORE NW FETCH. A LOOK            
 AT SOME OTHER MESOSCALE GUIDANCE SUCH AS THE FSL EXPERIMENTAL RUC              
 AND THE CANADIAN GEM SHOW MORE UNCERTAINTY...WITH BOTH THOSE MODELS            
 DEPICTING MORE NORTHERLY FLOW AND A MORE WESTWARD BAND PLACEMENT.              
 TYPICAL BIAS OF MESOSCALE MODELS ARE TO BE TOO FAR WEST WITH A                 
 DOMINANT BAND AT THE SOUTHERN END OF LAKE MICHIGAN. WITH THE VERY              
 POOR MODEL AGREEMENT AND CONSISTENCY...JUST NOT ENOUGH CONFIDENCE              
 ON BAND PLACEMENT OR MODE TO GO WITH AN LES WATCH YET. STILL ENOUGH            
 TIME FOR A SHORTER RANGE WATCH FROM THE MIDNIGHT SHIFT IF MODEL                
 GUIDANCE STARTS TO CONVERGE ON A COMMON SOLUTION. THIS DOES HAVE THE           
 POTENTIAL TO BE A MAJOR EVENT GIVEN STRONG THERMODYNAMICS...BUT ONLY           
 IF A DOMINANT BAND FORMS...AND THAT IS STILL QUITE UNCERTAIN.

 .DAYS 1-2...                                                                   
 MAIN CHALLENGE IS THE FIRST PERIOD AND JUST HOW COLD IT WILL GET               
 TONIGHT...ESPECIALLY OUT WEST OVER THE HIGH PLAINS "GLACIER".                  
 NORTHWEST WINDS WILL ABATE BY EARLY EVENING AND SHOULD SEE                     
 TEMPERATURES DROP RAPIDLY INTO THE 3 TO 6F DEGREE RANGE JUST BEFORE            
 MIDNIGHT.  THE AMOUNT OF CONTINUED DROPPING OF TEMPERATURE WILL BE             
 CONTROLLED BY HOW MUCH WIND THERE WILL BE...THE NAM AND RUC BOTH               
 SUGGEST JUST ENOUGH OF A NORTHWEST WIND AROUND 4 TO 6 KNOTS TO KEEP            
 FROM WIDESPREAD BELOW ZERO READINGS.  HOWEVER IF WINDS DO SLACKEN              
 OFF TO DEAD CALM FOR A FEW HOURS...THEN WE SHOULD SEE QUITE A FEW              
 READINGS IN THE -4 TO -8F RANGE...THIS IS STILL RATHER UNCERTAIN SO            
 WILL GO WITH AROUND -2 TO -3 OVER THE SNOWPACK IN THE WEST TO AROUND           
 +2 OR +3 OVER THE SOUTHEASTERN CWA.                                            
 FOR TUESDAY...CENTER OF 900MB ANTICYCLONE WILL BE PRETTY MUCH                  
 CENTERED OVER SOUTHWEST KANSAS BY LATE AFTERNOON.  WINDS WILL BE               
 VERY LIGHT DURING THE DAY...AND AM NOT EXPECTING MUCH OF A WARM-UP             
 OVER WHAT WE ARE SEEING TODAY FOR HIGHS...WITH PERHAPS A FEW UPPER             
 20S READINGS WHERE THERE IS MORE BARE GROUND OVER CENTRAL PORTIONS             
 OF THE CWA.                                                                    
 TUESDAY NIGHT...LOW LEVEL ANTICYCLONE FINALLY SHIFTS FAR ENOUGH                
 SOUTHEAST TO PUT SOUTHWEST KS INA RETURN SOUTHERLY FLOW...IT                   
 CERTAINLY WILL NOT BE A WARM WIND THOUGH.  LOWS TUES NIGHT WILL NOT            
 BE AS COLD WITH STRONGER SOUTH WINDS EXPECTED.  LEESIDE PRESSURE               
 FALLS WILL OCCUR IN ADVANCE OF BOTH A NORTHERN STREAM MID LEVEL                
 TROUGH AND A WEAK SOUTHERN STREAM SYSTEM.                                      
 WEDNESDAY...SOUTH WINDS WILL INCREASE QUITE A BIT WITH LEE TROUGH              
 BECOMING STRONGER TO THE NORTHWEST AS MID LEVEL SHORTWAVE TROUGH               
 PASS THROUGH THE PLAINS.  A NORTHWARD SURGE OF LOWER-MID                       
 TROPOSPHERIC MOISTURE IS ALSO EXPECTED...HOWEVER LIMITED LIFT AND              
 BAROCLINICITY WILL NEGATE PRECIPITATION FORMATION...JUST AN INCREASE           
 IN CLOUDS BY MIDDAY. -UMSCHEID

 MODELS DIFFER SLIGHTLY ON LOCATION OF UPPER CLOSED LOW LINGERING               
 OVER THE PACIFIC JUST WEST OF THE SOUTHERN CA COAST. ALSO SEEING               
 DISCREPANCIES BETWEEN MODELS REGARDING DEPTH OF TROUGHING ACROSS THE           
 CENTRAL PLAINS (MAINLY ACROSS WESTERN KS). GFS/CANADIAN ARE A BIT              
 DEEPER ALLOWING SLIGHTLY COLDER H85 TEMPERATURES TO SPILL ACROSS THE           
 CWA. UKMET IS SLOWEST SOLUTION BRINGING THE H5 CLOSED LOW INTO THE             
 CONUS. OTHER MODELS ALL MOVE LOW ONSHORE BY 00Z SUN. FOR NOW, A                
 MODEL BLEND WITH LESS WEIGHT ON THE OUTLIER, THE UKMET, WILL BE USED.          
 MAIN QUESTION CONTINUES TO BE PRECIPITATION CHANCES INTO THE WEEKEND.          
 MUCH UNCERTAINTY REMAINS ON HOW/WHEN UPPER LOW WILL MOVE INTO                  
 SOUTHERN CA. ONCE ONSHORE, THE SYSTEM LOCATION WILL MAKE A BIG                 
 DIFFERENCE ON WHETHER OR NOT WESTERN KS WILL RECEIVE ANY                       
 PRECIPITATION. MODELS DO HANG ONTO A DECENT SUBTROPICAL JET ALLOWING           
 PLENTY OF MOISTURE RETURN ACROSS WESTERN TX. STRONG HIGH PRESSURE              
 FORECAST TO MOVE SOUTH THUS KEEPING BULK OF PRECIP SOUTH OF CWA.               
 EVEN IF MOISTURE DOES MAKE IT INTO SOUTHWEST KS, IT DOES NOT APPEAR            
 THAT IT WILL ARRIVE UNTIL LATE SATURDAY NIGHT OR SUNDAY (GIVE                  
 SOLUTION IS CORRECT). DECIDED TO BACK OFF ON POPS ACROSS CWA DURING            
 THIS PERIOD. HAVE LEFT A SLIGHT CHANCE ACROSS THE SOUTHWESTERN                 
 COUNTIES STARTING SATURDAY NIGHT SINCE IT IS POSSIBLE THAT SOME                
 MOISTURE WILL MAKE IT INTO THIS REGION. REMAINDER OF CWA WILL BE               
 DRY. ONCE AGAIN, WILL HAVE TO KEEP A CLOSE EYE ON EVOLUTION OF THIS            
 SYSTEM SINCE DETAILS ARE RATHER SKETCHY AT PRESENT.

 .PREV DISCUSSION /907 PM CST SAT JAN 13 2007/...                               
 WILL UPDATE THE FORECAST SHORTLY FOR CURRENT CONDITIONS. FOR THE               
 MOST PART...PRECIP HAS ENDED ACROSS MOST OF THE FORECAST AREA. THERE           
 ARE SOME SMALL BANDS OF VERY LIGHT PRECIP SEEN ON RADAR. IT IS HARD            
 TO TELL IF THE PRECIP FALLING IS LIGHT FREEZING DRIZZLE OR POSSIBLY            
 SNOW NEEDLES...ITS THAT LIGHT. THE LATEST RUC FORECAST WAS SHOWING             
 SOME VERY LIGHT ISENTROPIC LIFT WITHIN THE CLOUD. THINK THIS MAY BE            
 THE REASON FOR THE LIGHT PRECIP. NEVERTHELESS DO NOT ANTICIPATE ANY            
 ACCUMULATING PRECIP FOR THE REST OF THE NIGHT SINCE LARGE SCALE                
 FORCING HAS LEFT THE AREA FOR THE TIME BEING.                                  
 MAIN QUESTION IS WHAT TO DO WITH THE WATCH. AM CONSIDERING REPLACING           
 THE WATCH WITH AN ADVISORY OF SOME SORT. THE 00Z NAM IS COMING IN              
 SHOWING A SIMILAR SOLUTION TO THE DAY TIME RUNS. AS THE BASE OF THE            
 UPPER LEVEL TROUGH ROTATES THROUGH THE SOUTHER ROCKIES AND INTO THE            
 WESTERN CENTRAL PLAINS...LARGE SCALE FORCING IS EXPECTED TO AFFECT             
 THE AREA ONCE AGAIN. HOWEVER THE FORCING DOES NOT LOOK TERRIBLY                
 IMPRESSIVE WITH THE UPPER WAVE SHEARING OUT AS IT MOVES INTO THE               
 PLAINS. WILL WAIT TO REPLACE THE WATCH AND PEEK AT THE 00Z GFS TO              
 SEE IF IT SHOWS SOMETHING DIFFERENT FROM THE EARLIER RUNS. IF THE              
 NAM IS CORRECT...LOOKS LIKE MAINLY SNOW WILL FALL ACROSS AREAS NORTH           
 AND WEST OF MHK WITH AROUND 2 INCHES POSSIBLE. ALONG THE TURNPIKE              
 WILL BE A LITTLE MORE PROBLEMATIC GIVEN FORECAST SOUNDINGS STILL               
 SHOWING A WARM NOSE AROUND 800MB THROUGH 21Z. WILL KEEP THE WINTER             
 STORM WARNING AS IS FOR THE TIME BEING...GIVEN THE POSSIBILITY FOR             
 DECENT SLEET ACCUMULATIONS ONCE AGAIN.                                         
 AVIATION WISE...EXPECT CURRENT CONDITIONS TO REMAIN RELATIVELY                 
 STABLE THROUGH THE OVERNIGHT PERIOD. OBVIOUSLY THE LIGHT PRECIP SEEN           
 ON RADAR WILL CAUSE A PROBLEM FOR AIRCRAFT. THIS SHOULD BE SPOTTY              
 THOUGH AND CONFINED TO AREAS BELOW 4000FT. SFC VIS WILL DROP TO                
 AROUND 4SM IN THESE LIGHT BANDS WITH CEILINGS AROUND 800FT.                    
 OTHERWISE ANTICIPATE A SLIGHT IMPROVEMENT TO THE CEILINGS AROUND               
 1000FT AS VERY WEAK ISENTROPIC LIFT BREAKS DOWN.

 BASE OF THE MAIN TROF PROGGED TO MAKE IT INTO NORTHERN NM BY

 ARE SEEN OVER THE SW US IN THE WATER VAPOR...STILL DIFFICULT TO                
 DISCERN WHICH WILL MAKE IT HERE AND WHEN. CONSENSUS SEEMS TO BE THAT           
 BEST WINDOW FOR ACCUMULATING SNOWS IS NOW MAINLY IN THE 15Z-0Z                 
 TIMEFRAME. GUIDANCE NUMBERS FOR SNOW HAVE COME DOWN...AND NOT MUCH             
 INSTABILITY IN THE COLUMN. BUT WITH SOME FRONTOGENESIS...POT VORT              
 AND Q VECTOR CONVERGENCE STILL OCCURING OVER OUR AREA AT THIS                  
 TIME...WILL KEEP SOME ADVISORY ACCUMULATIONS IN THE FORECAST FOR               
 MUCH OF THE CWA. FAR SE COUNTIES WHERE WARNING IS IN EFFECT HAVE               
 ALREADY SEEN OVER AN INCH OF SLEET IN PLACES...AND WILL BE                     
 EXACERBATED BY SOME SNOW ACCUMULATION ON TOP OF THIS TOMORROW. WITH            
 PWS AROUND HALF AN INCH AND SNOW RATIOS LIKELY OVER 10/1 IN THE COLD           
 AIR...AM NOT READY TO DROP THE WATCH JUST YET...AND WILL TREND GRIDS           
 TOWARDS ADVISORY NUMBERS.                                                      
 MAIN UPPER LEVEL WAVE FINALLY EJECTS OUT THROUGH THE PLAINS AND                
 EXITS TO THE NORTHEAST OF THE CWA BY 12Z MONDAY...BUT NOT BEFORE               
 PRODUCING SOME LIGHT SNOW ACROSS THE CWA...MAINLY DURING THE EVENING           
 ALONG AND NORTH OF I-70 AS DRIER AIR AND SUBSIDENCE INCREASE FROM              
 THE SOUTHWEST. ADDITIONAL AMOUNTS GENERALLY SHOULD BE FROM LESS THAN           
 HALF AN INCH SOUTH TO AN INCH TO AN INCH AND A HALF NORTHEAST CORNER           
 OF THE CWA. ALTHOUGH LOWS SUNDAY NIGHT WILL BE COLDER...CLOUDS AND             
 INCREASING WINDS WILL KEEP TEMPERATURES FROM FALLING AS MUCH AS THEY           
 OTHERWISE WOULD...SO WILL KEEP GENERALLY IN THE 5 TO 12 DEGREE RANGE.          
 THE STRATUS ON MONDAY WILL THEN LINGER IN THE MORNING BUT START TO             
 BREAK UP BY AFTERNOON. STILL...WITH EXPECTED SNOW/ICE COVER...THIS             
 WILL LIMIT HIGHS TO THE TEENS.                                                 
 TUESDAY NIGHT SHOULD BE THE COLDEST NIGHT WITH DIMINISHING                     
 WINDS...DECREASING CLOUDS AND SNOW/ICE COVER. WILL GO WITH MOST                
 TEMPS NEAR ZERO FOR NOW...BUT DEPENDING ON SNOW/ICE DEPTHS...COULD             
 SEE TEMPS A FEW DEGREES COLDER. ALTHOUGH SUNSHINE SHOULD BE THE RULE           
 ON TUESDAY...MIXING WILL BE WEAK FOLLOWING VERY COLD MORNING                   
 LOWS...SO THIS WILL LIMIT HIGHS TO UPPER TEENS TO LOWER 20S. RETURN            
 FLOW ON THE BACK SIDE OF THE HIGH SHOULD THEN KEEP LOWS ABOVE ZERO             
 INTO WEDNESDAY MORNING WITH MOST HIGHS IN THE MIDDLE TO UPPER 20S.             
 WILL KEEP THE REST OF THE FCST DRY ON THROUGH EARLY NEXT WEEKEND AS            
 THE GFS/ECMWF SEEMS TOO PROGRESSIVE AND TOO FAR EAST WITH CUTOFF LOW           
 COMING OUT OF THE SOUTHWEST U.S. WEDNESDAY. ALSO LOW CONFIDENCE WITH           
 THE ARRIVAL TIME OF THE NEXT SYSTEM BY SATURDAY.                               
 EITHER WAY...WITH THE SNOW/ICE COVER WILL SEE A "GRADUAL" MODERATION           
 IN TEMPS THROUGH THE REST OF THE WEEK INTO THE 30S THURSDAY AND

 ACARS SOUNDINGS AT SDF...AND MOST RECENT RUC MODEL...PRECIP TYPE               
 SHOULD BE LIQUID. ADDITIONAL LIGHT PRECIP OBSERVED UPSTREAM OVER               
 IL/IN...HEADING IN THIS GENERAL DIRECTION. OVERNIGHT...PTYPE WILL BE           
 TRICKY. AS IS THE SITUATION RIGHT NOW...FCST SOUNDINGS FROM                    
 NAM/GFS/RUC SHOW ATMOSPHERE ABOVE -5C OR SO REMAINING FAIRLY DRY               
 OVERNIGHT...LEADING TO MORE OF A DRIZZLE ENVIRONMENT. THIS IS EVEN             
 AS THE NEAR SURFACE LEVELS COOL TO NEAR OR BELOW FREEZING.                     
 WILL UPDATE FCST TO ADD MENTION OF PATCHY -FZDZ LATE TONIGHT AND               
 EARLY TUESDAY MORNING OVER THE N 1/2 OF THE LMK CWA...ALSO                     
 MENTIONING SLIGHT CHANCES FOR -SHRA/-SHSN FOR ANY ISOLATED ELEMENTS            
 WHICH CAN SATURATE UP INTO THE -10C TO -20C LEVELS OVERNIGHT.                  
 ROADWAY TEMPS RIGHT NOW ARE RELATIVELY WARM...UPPER 30S TO LOWER               
 40S...BUT EXPECT THOSE TO COOL OVERNIGHT ESPECIALLY IN SRN IND AND             
 ADJACENT PARTS OF KY. EVEN JUST A LITTLE -FZDZ CAN HAVE A BIG IMPACT.          
 INTO TUESDAY...MODELS ARE INDICATING THAT A PLUME OF ENHANCED                  
 MOISTURE ORIGINATING FROM LAKE MICH MAY CONTRIBUTE TO SOME SCT SHSN            
 INTO PARTS OF THE BLUEGRASS AND NE KY. ONGOING FCST HAS THIS WELL IN           
 HAND...BUT HAVE UPPED POPS INTO 40% RANGE FOR OUR FAR NE MOST                  
 COUNTIES BASED ON MOST RECENT DATA. SOME LOCALIZED MINOR ACCUMS

 .SHORT TERM.../TODAY/...UPDATED                                                
 MAIN CHANGES TO THE FORECAST FOR TODAY WAS TO LOWER POPS...AND RAISE           
 TEMPERATURES. TEMPERATURES WERE RUNNING IN THE MID 60S ALREADY IN THE          
 SOUTHERN PORTION OF THE CWA...TAPERING TO THE UPPER 50S IN THE NORTH.          
 MORNING RADIOSONDE SOUNDINGS WOULD YIELD HIGH TEMPS AROUND 70 IN THE           
 SOUTH...WITH LOWER TO MID 60S IN THE NORTH. THESE WILL LIKELY NEAR             
 RECORD VALUES IN THE NORTH...AND EXCEED THEM IN THE SOUTH. THE RECORD          
 HIGH TODAY AT JKL IS 68...AND 64 AT LOZ. MUCH OF THE PRECIP HAS MOVED          
 NORTH OF THE CWA AS THE QUASI STATIONARY FRONT OSCILLATES BACK NORTH           
 AHEAD OF AN APPROACHING WAVE. WENT WITH LIKELY POPS ACROSS THE                 
 EXTREME NORTH FOR THE AFTERNOON. WENT WITH LOW CHANCE POPS FOR MOST            
 OF THE REMAINDER OF THE AREA. IN THE SOUTHEAST...WENT WITH A SLIGHT            
 CHANCE. ALL MODELS SHOW A LULL IN THE PRECIP TODAY. WILL KEEP FLOOD            
 WATCH GOING TODAY. EVEN WITH A LULL IN THE PRECIP...STREAMS AND                
 CREEKS ARE RUNNING HIGH IN THE WATCH AREA. ANY ADDITIONAL PRECIP               
 DURING THE AFTERNOON COULD SEND THESE TO NEAR BANK FULL OR ABOVE. THE          
 BEST CHANCE FOR FLOODING WILL BE TONIGHT INTO MONDAY. AFTERNOON QPF            
 SHOULD RANGE FROM NEAR ZERO IN THE SOUTH...TO NEAR 0.20 IN THE NORTH.          
 SURFACE FRONT IS CURRENTLY RUNNING FROM JUST NORTH OF CVG...TO PAH.            
 MOST OF THE PRECIP TODAY WILL BE FOCUSED NEAR THE FRONT. NO OTHER              
 CHANGES WERE MADE TO THE FORECAST ATTM. THE EARLIER MORNING                    
 DISCUSSION IS BELOW.                                                           
 /TONIGHT THROUGH TUESDAY/                                                      
 FRONT SHOULD EVENTUALLY MAKE ITS EASTWARD PUSH TONIGHT...AS A STRONG           
 SHORT WAVE EJECTS OUT OF THE SOUTHERN PLAINS. WITH STRONG HIGH                 
 PRESSURE STILL SITTING OF THE SOUTHEASTERN UNITED STATES...FRONT WILL          
 BE SLOW TO EXIT REGION. ANTICIPATING THAT FRONT WONT MOVE EAST OF JKL          
 CWA UNTIL SOMETIME MONDAY NIGHT. LEFT IN FLOOD WATCH FOR NORTHWESTERN          
 COUNTIES DUE TO PERSISTANT RAINS THERE. SOUTHERN HALF OF CWA HADNT             
 SEEN NEARLY AS MUCH RAIN AS THE NORTHWEST...SO FLOODING IS NOT MUCH            
 OF A CONCERN.                                                                  
 WINDS AND DEWPOINTS WERE ALREADY IN GOOD SHAPE WITH ONLY A FEW MINOR           
 TWEAKS MADE BASED UPON LATEST MODEL RUNS AND MOS GUIDANCE. MADE A              
 FEW CHANGES TO SKY COVER FOR TONIGHT...MAINLY TO REFLECT SLOWER                
 EASTWARD PROGRESS OF FRONT. POP FORECAST ALSO MODIFIED QUITE A                 
 BIT...WITH LOWER POPS INTRODUCED TO SOUTHERN HALF OF CWA AND A MUCH            
 SLOWER ONSET OF MAIN PRECIPITATION EVENT. LOOKING FOR MAIN PUSH OF             
 RAIN TO MOVE THROUGH THE CWA BEGINNING LATER TONIGHT THROUGH MONDAY            
 NIGHT. SOME AREAS IN THE NORTHERN PORTION OF CWA COULD RECEIVE A               
 COUPLE OF INCHES OF RAIN OUT THIS NEXT ROUND OF PRECIP. EVERYWHERE             
 ELSE SHOULD RECEIVE LESS THAN AN INCH. COULD ALSO SEE SNOW SHOWERS             
 LATE MONDAY NIGHT INTO TUESDAY...AS THE COLDEST AIR OF THE WINTER              
 SEASON BEGINS TO FILTER INTO THE AREA BEHIND A DEPARTING COLD FRONT.           
 FOR TEMPERATURES...WENT WITH A BLEND OF MAV/MET MOS ACROSS THE                 
 BOARD. WENT BELOW MOS FOR DAYTIME HIGHS...DUE TO EXTENSIVE CLOUD               
 COVER...AND A BIT WARMER THAN MOS FOR OVERNIGHT LOWS SUNDAY NIGHT              
 AND MONDAY NIGHT. WENT VERY CLOSE TO MEXMOS NUMBERS FOR WEDNESDAYS             
 HIGHS. DEPENDING ON AMOUNT OF CLOUD COVER IN PLACE...A FEW AREAS               
 COULD BE A BIT COOLER THAN MOS.                                                
 .LONG TERM.../WEDNESDAY THROUGH SATURDAY/                                      
 MODELS SOLUTIONS FOR THE END OF THE WEEK HAVE CHANGED FROM THE                 
 PREVIOUS RUNS. GFS BRINGS MOISTURE...AND A SURFACE WAVE...UP FROM              
 THE GULF OF MEXICO ON FRIDAY INTO SATURDAY. ECMWF HAS ALSO TRENDED             
 FURTHER NORTH WITH THIS SYSTEM. DGEX AND NOGAPS KEEPS THIS FURTHER             
 SOUTH. ALL MODELS SHOW AN APPROACHING COLD FRONT FOR LATER FRIDAY.             
 INTRODUCED CHANCE POPS FOR FRIDAY INTO SATURDAY WITH ALL OF THIS IN            
 MIND. ATTM...THINK THE COLD FRONT WILL LIKELY HAVE ENOUGH MOISTURE             
 TO AT LEAST WARRANT CHANCE POPS FOR NOW. PRECIP TYPE IS IN                     
 QUESTION...WITH MARGINAL TEMPERATURES AT ALL LEVELS. FOR NOW...WENT            
 WITH A MENTION OF RAIN AND SNOW. COLDER AIR WILL FILTER INTO THE               
 AREA FRIDAY NIGHT INTO SATURDAY AS THE COLD FRONT MOVES THROUGH.               
 THERE IS STILL UNCERTAINTY IN THE LATER PORTION OF THE EXTENDED...SO           
 THE FORECAST WILL LIKELY NEED TO BE FINE TUNED AS TIME GOES ON.                
 &&

 FRONTAL BOUNDARY STALLED JUST NORTHWEST OF THE AREA CONTINUES TO               
 SEND WAVES OF SHOWERS NORTH OF INTERSTATE 64. NO REAL REASON FOR THE           
 FRONT TO PUSH SOUTH...AND IN FACT IT WILL LIKELY WAFFLE BACK NORTH             
 SOME TODAY AS LOW PRESSURE FORMS OVER THE LOWER MISSISSIPPI VALLEY             
 AND THEN HEADS NORTH. THIS SHOULD RESULT IN AREA TAF SITES REMAINING           
 VFR THROUGH THE DAY. ONE WRINKLE IN THIS THEORY IS A CONVECTIVELY              
 INDUCED VORTICITY MAXIMUM WHICH SHOWS UP ON WATER VAPOR SATELLITE              
 IMAGERY OVER MISSISSIPPI. RUC...AND TO SOME EXTENT THE NAM...PICK UP           
 ON THIS FEATURE AND MOVE IT NORTHEAST ACROSS THE AREA THIS                     
 AFTERNOON. THIS MAY PROVIDE ENOUGH LIFT FOR SOME SHOWERS...BUT WILL            
 MAINTAIN VFR CONDITIONS FOR NOW.                                               
 CONDITIONS SHOULD FINALLY DETERIORATE LATER TONIGHT AS THE SURFACE             
 WAVE MOVES NORTHEAST ACROSS THE WESTERN HALF OF THE STATE. HAVE                
 DELAYED ONSET OF MVFR CIGS/VSBYS A FEW HOURS FROM EARLIER THINKING             
 AS LATEST GUIDANCE IS A TOUCH SLOWER AND FARTHER WEST WITH THE                 
 SURFACE LOW. WINDS WILL ALSO BECOME GUSTY AFTER MIDNIGHT WITH SOME             
 BORDERLINE LLWS AS MODELS DEVELOP A STRONG LOW LEVEL JET IN EXCESS             
 OF 40 KT AROUND 2K FT AGL AND ABOVE.

 QUASI STATIONARY FRONTAL BOUNDARY IS STILL DRAPED ACROSS THE AREA              
 THIS MORNING.  LOTS OF CLOUDS AND SEVERAL AREAS OF LIGHT                       
 PRECIPITATION WERE NOTED ACROSS THE REGION THIS MORNING.  GENERAL              
 DOWNWARD TREND IN PRECIPITATION HAS BEEN NOTED AND THIS WILL LIKELY            
 CONTINUE THROUGH THE EARLY AFTERNOON AS EARLY MORNING SFC WAVE                 
 CONTINUES TO MOVE NE AND AWAY FROM THE REGION.                                 
 FOR THE REMAINDER OF THE MORNING AND INTO THE AFTERNOON...LOOKS LIKE           
 WE`LL SEE A SHORT LULL IN THE ACTION AS WE WILL BE IN BETWEEN SFC              
 WAVES.  AREAS OF LIGHT RAIN AND DRIZZLE WILL CONTINUE TO MOVE ACROSS           
 THE REGION WITH BEST PRECIP CHANCES ALONG AND NORTH OF A LINE FROM             
 ALLEN COUNTY TO LINCOLN COUNTY.  THOSE FAR SE COUNTIES MAY STAY                
 FAIRLY DRY THROUGH THE AFTERNOON.  AS FOR TEMPERATURES...WE WILL               
 CONTINUE TO SEE A DECENT GRADIENT ACROSS THE REGION.  AFTERNOON                
 HIGHS IN THE MID TO UPPER 50S WILL BE SEEN IN SOUTHERN INDIANA WITH            
 60S ALONG AND SOUTH OF THE OHIO RIVER ACROSS NORTH CENTRAL AND THE             
 BLUEGRASS REGION OF KY.  62-66 DEGREE READINGS WILL BE POSSIBLE                
 ACROSS THE SE THIRD OF THE REGION.  CURRENT FCST HAS THIS WELL IN              
 HAND AND ONLY SOME MINOR ADJUSTMENTS TO TEMPS WILL BE NEEDED.                  
 GENERAL CONSENSUS OF 06Z AND EARLY 12Z MODEL DATA SUGGEST NEXT WAVE            
 TO MOVE INTO THE REGION LATE THIS AFTERNOON AND EVENING.  LIGHT TO             
 MODERATE RAIN WILL OVERSPREAD THE REGION FROM WEST TO EAST TONIGHT.            
 AXIS OF HIGHEST PRECIPITATION AGAIN LOOKS TO BE ALONG THE OHIO RIVER           
 WITH THE HIGHEST QPF IN OUR WEST CENTRAL SECTIONS (SOUTH OF THE OHIO           
 AND WEST OF I-65).  THEREFORE...WILL ALLOW POPS TO RAPIDLY INCREASE            
 FROM WEST TO EAST DURING THE LATE AFTERNOON HOURS.                             
 HYDRO ISSUES...PRECIP AMOUNTS FROM THE PAST 24 HOURS HAVE BEEN                 
 BETWEEN 0.75 AND A LITTLE OVER ONE INCH.  THIS HAS RESULTED IN RISES           
 ON AREA RIVERS...BUT AS A WHOLE...THINGS HAVE BEEN OKAY SO FAR.                
 GROUND SATURATION HAS NOW BEEN REACHED OVER MUCH OF THE REGION AND             
 FLASH FLOOD GUIDANCE CONTINUES TO DROP.  THUS...WITH ADDITIONAL                
 RAINFALL LATE THIS AFTERNOON AND TONIGHT...WE COULD START SEEING               
 SOME HYDRO ISSUES IN OUR WESTERN COUNTIES.  THERE IS SOME CONCERN              
 THAT THE FLOODING AND HYDRO ISSUES MAY NOT BE REALIZED IN THE SE               
 SECTIONS OF THE FA.  HOWEVER...THE 06Z GFS SOLUTIONS DO BRING DECENT           
 QPF AMOUNTS INTO THE AREA LATE TONIGHT AND MONDAY.  THEREFORE...WE             
 MAY NEED TO EXTEND THE FLOOD WATCH IN TIME THROUGH MONDAY MORNING.             
 DECISIONS ON THE FLOOD WATCH WILL BE MADE DURING THE AFTERNOON                 
 PACKAGE AS FULL 12Z MODEL DATA WILL BE AVAILABLE.                              
 AS FOR RIVER IMPACTS...WITH THE RAIN THATS ALREADY FALLEN AND                  
 EXPECTED QPF FOR TONIGHT...OUR OHIO RIVER POINTS STILL LOOK TO GO              
 INTO MINOR FLOOD IN THE NEXT FEW DAYS.  WE`RE ALSO WATCHING THE                
 ROLLING FOR RIVER AND GREEN RIVERS IN KY AS EXPECTED QPF WILL PUSH             
 THEM INTO MINOR FLOODING AS WELL.                                              
 UPDATED FCST SUITE AND PRODUCTS WILL BE AVAILABLE BY 1130 AM EST.

 .SHORT TERM (TODAY AND TONIGHT)...                                             
 CURRENTLY...A QUASI-STATIONARY FRONT IS ALIGNED ROUGHLY FROM SOUTH             
 OF CINCINNATI...TO LOUISVILLE...TO MEMPHIS. SFC LOW PRESSURE                   
 WAVES RIDING ALONG THIS FRONT AND AMPLE MOISTURE HAVE BEEN                     
 RESPONSIBLE FOR THE RAINFALL OVER THE PAST 1-2 DAYS. RAINFALL                  
 TOTALS ACROSS THE CWA OVER THE PAST 24 HOURS HAVE RANGED FROM                  
 AROUND A TENTH OF AN INCH ACROSS THE SERN CWA TO ROUGHLY THREE-                
 QUARTERS OF AN INCH ACROSS THE WNW. ANOTHER SFC WAVE OVER WRN TN               
 IS HELPING PUMP MOISTURE NORTHWARD ALONG THE FRONT INTO OUR WRN                
 CWA ATTM. THIS WILL BE THE FIRST OF TWO MAIN WAVES OF MOD-TO-HEAVY             
 RAINFALL FOR THE CWA.                                                          
 BASED OFF THE 00Z NAM (WHICH HAS THE BEST HANDLE ON CURRENT RADAR              
 IMAGERY)...THE TN SFC WAVE WILL RIDE ALONG THE FRONT WHICH WILL BE             
 NEARLY PARALLEL TO THE OHIO RIVER. THUS THE HEAVIEST RAINFALL IS               
 EXPECTED ALONG AND AROUND THE OHIO RIVER THROUGH THE MORNING HOURS             
 AND PERHAPS INTO THE EARLY AFTERNOON HOURS. BOTH THE NAM AND RUC               
 (AND WRF) THINK THAT OUR SERN CWA COULD GET BY TODAY WITH ONLY A               
 FEW LIGHT RAIN SHOWERS. HAVE BACKED OFF ON POPS DOWN THERE TO                  
 ACCOUNT FOR THIS TREND. EVEN THOUGHT OF CANCELING THE WATCH                    
 ACROSS OUR FAR SERN CWA...BUT WE MAY SEE ENOUGH PRECIP WITH THE                
 SECOND WAVE TO JUSTIFY IT. SOMETHING THE NEXT SHIFT WILL CERTAINLY             
 HAVE TO CONSIDER THOUGH. WELL...THE FIRST WAVE OF POTENTIALLY HEAVY            
 RAIN IS CURRENTLY CAUSING MINOR FLOODING PROBLEMS IN PAH`S                     
 CWA...BUT OTHER THAN SOME HEAVY RAIN AT TIMES AND STANDING WATER               
 IN LOW-LYING AREAS...IT SHOULD NOT POSE A FLOOD THREAT YET. RAIN               
 TOTALS AFTER THIS FIRST WAVE COULD RANGE FROM A HALF INCH UP TO                
 OVER AN INCH OF RAINFALL BY MIDDAY.                                            
 OTHER THAN OFF AND ON RAIN...THE NEXT MAIN WAVE OF PRECIP WILL                 
 COME THROUGH LATE TONIGHT AS THE MAIN SFC LOW RIDES UP ALONG THE               
 FRONT TONIGHT. THIS SHOULD SUPPORT THE BEST CHANCE AT FLOODING                 
 RAINS...WITH AID FROM THE RIGHT-ENTRANCE REGION OF 120-KT UPPER                
 JET AND STRONG LLJ OF 60KTS. THUS WE COULD SEE ADDITIONAL RAINFALL             
 AMOUNTS OF ANOTHER ONE TO MAYBE TWO INCHES. DO NOT SEE CONVECTION              
 BEING A THREAT AS NAM AND GFS SFC AND ELEVATED INSTABILITY IS NON-             
 EXISTENT FROM THE 00Z RUNS. THUS WILL REMOVE THUNDER WORDING.                  
 DESPITE LACK OF CONVECTION...THINK RAINFALL TOTALS COULD RANGE                 
 FROM 2-3 INCHES...WITH LOCALLY HIGHER AMOUNTS. THIS COULD LEAD TO              
 MINOR FLOODING...WITH THE BEST CHANCE OCCURRING FOR SRN IN AND NRN             
 KY LATE TONIGHT WITH THE SECOND WAVE OF PRECIP. THUS...FLOOD WATCH             
 STILL SEEMS WARRANTED AND AM ACTUALLY INCLINED TO EXTEND IT TO 12Z             
 MONDAY. MAY DEFER THIS TO DAY SHIFT THOUGH.                                    
 FOR AVIATION CONCERNS...OTHER THAN VARIABLE LIFR CIGS AND                      
 VIS`S...WILL HAVE LLWS TONIGHT WITH STRONG 850MB JET.                          
 WILL HAVE QUITE THE TEMP GRADIENT FOR HIGHS TODAY...WITH LOW 60S               
 SE TO AROUND 50 NW. ADDITIONALLY...WINDS MAY BE GUSTY TODAY AND                
 TONIGHT...ESPECIALLY ACROSS THE SRN AND SERN CWA WITH GUSTS AROUND             
 20 MPH OR SO POSSIBLE.

 AT THE BEGINNING OF THIS PERIOD WE FIND AN UPPER LEVEL RIDGE PARKED            
 OVER THE EASTERN GULF OF MEXICO AND FLORIDA WITH A TROUGH WORKING              
 ACROSS THE UPPER MISSISSIPPI VALLEY. THE LAST WAVE OF LOW PRESSURE             
 ALONG THE ARCTIC FRONT WILL MOVE FROM THE UPPER OHIO VALLEY ON ITS             
 WAY TO THE NORTHEAST COAST. AN ASSOCIATED COLD FRONT WILL SWEEP                
 ACROSS THE FORECAST AREA DURING THE DAY MONDAY. IN ITS WAKE A                  
 NORTHERLY FLOW WILL BRING MORE WINTER LIKE TEMPERATURES INTO THE               
 LOWER OHIO VALLEY. PRECIPITATION (HEAVY AT TIMES ACROSS THE                    
 SOUTHEAST MONDAY MORNING) WILL END AS THE COLD AIR ARRIVES ALTHOUGH            
 THERE MAY BE SOME RAIN AND SNOW MIXED ACROSS SOUTHERN INDIANA MONDAY

 .SHORT TERM.../TODAY THROUGH TUESDAY/                                          
 WENT WITH GFS SOLUTION FOR SHORT TERM. BASED ON CURRENT TRENDS...              
 SLOWED DOWN EASTWARD PROGRESSION OF FRONT BY A FEW HOURS...CONFINING           
 HIGHEST PRECIP CHANCES TO NORTHWEST COUNTIES OF CWA THIS MORNING.              
 FRONT SHOULD EVENTUALLY MAKE ITS EASTWARD PUSH LATER THIS AFTERNOON            
 INTO TONIGHT...AS A STRONG SHORT WAVE EJECTS OUT OF THE SOUTHERN               
 PLAINS. WITH STRONG HIGH PRESSURE STILL SITTING OF THE SOUTHEASTERN            
 UNITED STATES...FRONT WILL BE SLOW TO EXIT REGION. ANTICIPATING THAT           
 FRONT WONT MOVE EAST OF JKL CWA UNTIL SOMETIME MONDAY NIGHT. LEFT IN           
 FLOOD WATCH FOR NORTHWESTERN COUNTIES DUE TO PERSISTANT RAINS THERE.           
 SOUTHERN HALF OF CWA HADNT SEEN NEARLY AS MUCH RAIN AS THE                     
 NORTHWEST...SO FLOODING IS NOT MUCH OF A CONCERN.                              
 WINDS AND DEWPOINTS WERE ALREADY IN GOOD SHAPE WITH ONLY A FEW MINOR           
 TWEAKS MADE BASED UPON LATEST MODEL RUNS AND MOS GUIDANCE. MADE A              
 FEW CHANGES TO SKY COVER FOR THE TODAY AND TONIGHT...MAINLY TO                 
 REFLECT SLOWER EASTWARD PROGRESS OF FRONT. POP FORECAST ALSO                   
 MODIFIED QUITE A BIT...WITH LOWER POPS INTRODUCED TO SOUTHERN HALF             
 OF CWA AND A MUCH SLOWER ONSET OF MAIN PRECIPITATION EVENT. LOOKING            
 FOR MAIN PUSH OF RAIN TO MOVE THROUGH THE CWA BEGINNING LATER                  
 TONIGHT THROUGH MONDAY NIGHT. SOME AREAS IN THE NORTHERN PORTION OF            
 CWA COULD RECEIVE A COUPLE OF INCHES OF RAIN OUT THIS NEXT ROUND OF            
 PRECIP. EVERYWHERE ELSE SHOULD RECEIVE LESS THAN AN INCH. COULD ALSO           
 SEE SNOW SHOWERS LATE MONDAY NIGHT INTO TUESDAY...AS THE COLDEST               
 AIR OF THE WINTER SEASON BEGINS TO FILTER INTO THE AREA BEHIND A               
 DEPARTING COLD FRONT.                                                          
 FOR TEMPERATURES...WENT WITH A BLEND OF MAV/MET MOS ACROSS THE                 
 BOARD. WENT BELOW MOS FOR DAYTIME HIGHS...DUE TO EXTENSIVE CLOUD               
 COVER...AND A BIT WARMER THAN MOS FOR OVERNIGHT LOWS SUNDAY NIGHT              
 AND MONDAY NIGHT. WENT VERY CLOSE TO MEXMOS NUMBERS FOR WEDNESDAYS             
 HIGHS. DEPENDING ON AMOUNT OF CLOUD COVER IN PLACE...A FEW AREAS               
 COULD BE A BIT COOLER THAN MOS.                                                
 .LONG TERM.../WEDNESDAY THROUGH SUNDAY/                                        
 MODELS SOLUTIONS FOR THE END OF THE WEEK HAVE CHANGED FROM THE                 
 PREVIOUS RUNS. GFS BRINGS MOISTURE...AND A SURFACE WAVE...UP FROM              
 THE GULF OF MEXICO ON FRIDAY INTO SATURDAY. ECMWF HAS ALSO TRENDED             
 FURTHER NORTH WITH THIS SYSTEM. DGEX AND NOGAPS KEEPS THIS FURTHER             
 SOUTH. ALL MODELS SHOW AN APPROACHING COLD FRONT FOR LATER FRIDAY.             
 INTRODUCED CHANCE POPS FOR FRIDAY INTO SATURDAY WITH ALL OF THIS IN            
 MIND. ATTM...THINK THE COLD FRONT WILL LIKELY HAVE ENOUGH MOISTURE             
 TO AT LEAST WARRANT CHANCE POPS FOR NOW. PRECIP TYPE IS IN                     
 QUESTION...WITH MARGINAL TEMPERATURES AT ALL LEVELS. FOR NOW...WENT            
 WITH A MENTION OF RAIN AND SNOW. COLDER AIR WILL FILTER INTO THE               
 AREA FRIDAY NIGHT INTO SATURDAY AS THE COLD FRONT MOVES THROUGH.               
 THERE IS STILL UNCERTAINTY IN THE LATER PORTION OF THE EXTENDED...SO           
 THE FORECAST WILL LIKELY NEED TO BE FINE TUNED AS TIME GOES ON.                
 &&                                                                             
 .AVIATION.../12Z TO 12Z/...UPDATED                                             
 FRONTAL BOUNDARY STALLED JUST NORTHWEST OF THE AREA CONTINUES TO               
 SEND WAVES OF SHOWERS NORTH OF INTERSTATE 64. NO REAL REASON FOR THE           
 FRONT TO PUSH SOUTH...AND IN FACT IT WILL LIKELY WAFFLE BACK NORTH             
 SOME TODAY AS LOW PRESSURE FORMS OVER THE LOWER MISSISSIPPI VALLEY             
 AND THEN HEADS NORTH. THIS SHOULD RESULT IN AREA TAF SITES REMAINING           
 VFR THROUGH THE DAY. ONE WRINKLE IN THIS THEORY IS A CONVECTIVELY              
 INDUCED VORTICITY MAXIMUM WHICH SHOWS UP ON WATER VAPOR SATELLITE              
 IMAGERY OVER MISSISSIPPI. RUC...AND TO SOME EXTENT THE NAM...PICK UP           
 ON THIS FEATURE AND MOVE IT NORTHEAST ACROSS THE AREA THIS                     
 AFTERNOON. THIS MAY PROVIDE ENOUGH LIFT FOR SOME SHOWERS...BUT WILL            
 MAINTAIN VFR CONDITIONS FOR NOW.                                               
 CONDITIONS SHOULD FINALLY DETERIORATE LATER TONIGHT AS THE SURFACE             
 WAVE MOVES NORTHEAST ACROSS THE WESTERN HALF OF THE STATE. HAVE                
 DELAYED ONSET OF MVFR CIGS/VSBYS A FEW HOURS FROM EARLIER THINKING             
 AS LATEST GUIDANCE IS A TOUCH SLOWER AND FARTHER WEST WITH THE                 
 SURFACE LOW. WINDS WILL ALSO BECOME GUSTY AFTER MIDNIGHT WITH SOME             
 BORDERLINE LLWS AS MODELS DEVELOP A STRONG LOW LEVEL JET IN EXCESS

 .SHORT TERM (TODAY AND TONIGHT)...                                             
 CURRENTLY...A QUASI-STATIONARY FRONT IS ALIGNED ROUGHLY FROM SOUTH             
 OF CINCINNATI...TO LOUISVILLE...TO MEMPHIS. SFC LOW PRESSURE                   
 WAVES RIDING ALONG THIS FRONT AND AMPLE MOISTURE HAVE BEEN                     
 RESPONSIBLE FOR THE RAINFALL OVER THE PAST 1-2 DAYS. RAINFALL                  
 TOTALS ACROSS THE CWA OVER THE PAST 24 HOURS HAVE RANGED FROM                  
 AROUND A TENTH OF AN INCH ACROSS THE SERN CWA TO ROUGHLY THREE-                
 QUARTERS OF AN INCH ACROSS THE WNW. ANOTHER SFC WAVE OVER WRN TN               
 IS HELPING PUMP MOISTURE NORTHWARD ALONG THE FRONT INTO OUR WRN                
 CWA ATTM. THIS WILL BE THE FIRST OF TWO MAIN WAVES OF MOD-TO-HEAVY             
 RAINFALL FOR THE CWA.                                                          
 BASED OFF THE 00Z NAM (WHICH HAS THE BEST HANDLE ON CURRENT RADAR              
 IMAGERY)...THE TN SFC WAVE WILL RIDE ALONG THE FRONT WHICH WILL BE             
 NEARLY PARALLEL TO THE OHIO RIVER. THUS THE HEAVIEST RAINFALL IS               
 EXPECTED ALONG AND AROUND THE OHIO RIVER THROUGH THE MORNING HOURS             
 AND PERHAPS INTO THE EARLY AFTERNOON HOURS. BOTH THE NAM AND RUC               
 (AND WRF) THINK THAT OUR SERN CWA COULD GET BY TODAY WITH ONLY A               
 FEW LIGHT RAIN SHOWERS. HAVE BACKED OFF ON POPS DOWN THERE TO                  
 ACCOUNT FOR THIS TREND. EVEN THOUGHT OF CANCELING THE WATCH                    
 ACROSS OUR FAR SERN CWA...BUT WE MAY SEE ENOUGH PRECIP WITH THE                
 SECOND WAVE TO JUSTIFY IT. SOMETHING THE NEXT SHIFT WILL CERTAINLY             
 HAVE TO CONSIDER THOUGH. WELL...THE FIRST WAVE OF POTENTIALLY HEAVY            
 RAIN IS CURRENTLY CAUSING MINOR FLOODING PROBLEMS IN PAH`S                     
 CWA...BUT OTHER THAN SOME HEAVY RAIN AT TIMES AND STANDING WATER               
 IN LOW-LYING AREAS...IT SHOULD NOT POSE A FLOOD THREAT YET. RAIN               
 TOTALS AFTER THIS FIRST WAVE COULD RANGE FROM A HALF INCH UP TO                
 OVER AN INCH OF RAINFALL BY MIDDAY.                                            
 OTHER THAN OFF AND ON RAIN...THE NEXT MAIN WAVE OF PRECIP WILL                 
 COME THROUGH LATE TONIGHT AS THE MAIN SFC LOW RIDES UP ALONG THE               
 FRONT TONIGHT. THIS SHOULD SUPPORT THE BEST CHANCE AT FLOODING                 
 RAINS...WITH AID FROM THE RIGHT-ENTRANCE REGION OF 120-KT UPPER                
 JET AND STRONG LLJ OF 60KTS. THUS WE COULD SEE ADDITIONAL RAINFALL             
 AMOUNTS OF ANOTHER ONE TO MAYBE TWO INCHES. DO NOT SEE CONVECTION              
 BEING A THREAT AS NAM AND GFS SFC AND ELEVATED INSTABILITY IS NON-             
 EXISTENT FROM THE 00Z RUNS. THUS WILL REMOVE THUNDER WORDING.                  
 DESPITE LACK OF CONVECTION...THINK RAINFALL TOTALS COULD RANGE                 
 FROM 2-3 INCHES...WITH LOCALLY HIGHER AMOUNTS. THIS COULD LEAD TO              
 MINOR FLOODING...WITH THE BEST CHANCE OCCURRING FOR SRN IN AND NRN             
 KY LATE TONIGHT WITH THE SECOND WAVE OF PRECIP. THUS...FLOOD WATCH             
 STILL SEEMS WARRANTED AND AM ACTUALLY INCLINED TO EXTEND IT TO 12Z             
 MONDAY. MAY DEFER THIS TO DAY SHIFT THOUGH.                                    
 FOR AVIATION CONCERNS...OTHER THAN VARIABLE LIFR CIGS AND                      
 VIS`S...WILL HAVE LLWS TONIGHT WITH STRONG 850MB JET.

 LIGHT SNOW SUPPORTED BY 700-300 QVECTOR AHEAD OF THE MID LVL TROF              
 WAS DIMINISHING BUT VSBYS REMAINED GENERALLY IN THE 2-4SM RANGE FROM           
 NRN WI INTO SRN UPR MI AT 20Z. MULTIPLE WIND PARALLEL LES BANDS INTO           
 NRN UPR MI WERE BRINGING OCNLY HEAVY SNOW ESPECIALLY INTO THE HIGHER

 .SHORT TERM...TONIGHT AND TUESDAY                                              
 WITH OUR RECENT STORM TRACKING EAST OF THE GREAT LAKES...RESIDUAL              
 DEFORMATION AXIS OF SNOW WILL MOVE ACROSS THE REGION THIS EVENING.             
 CROSS SECTIONS NICELY DEPICT THIS DEFORMATION ZONE CENTERED BETWEEN            
 600-700MB WITH VISIBILITIES UNDER THE BAND OF SNOW DROPPING TO LESS            
 THAN 1 MILE.  IN FACT...SOME LAKE HURON CONTRIBUTION IS NOTED WITH A           
 NARROW BAND OF SNOW COMING DOWN ACROSS SAGINAW BAY INTO MBS WITH 1/4           
 MILE VISIBILITY.  LATEST RUC INCLUDING THE 12Z MODEL SUITE SUGGEST             
 THE 1000-850MB WIND WILL BACK TOWARD THE NORTH THIS EVENING AS THIS            
 DEFORMATION AXIS SWINGS SOUTH-SOUTHEAST ACROSS THE STATE.  SPECIFIC            
 HUMIDITIES ARE RUNNING AROUND 1 G/KG AND ACCUMULATIONS COULD ADD UP            
 TO ANOTHER 1 INCH NORTH OF M59 THIS EVENING.  FURTHER SOUTH...WITH             
 THE BOUNDARY LAYER BECOMING MORE NORTHERLY...EXPECT SOME DOWNSLOPING           
 INFLUENCES TO REDUCE THE SNOWFALL AMOUNTS AND DEFORMATION AXIS                 
 WEAKENING AS THE SURFACE TROUGH AND UPPER LEVEL TROUGH SWING                   
 SOUTHEAST OF THE STATE.  THEN THE REAL COLD ADVECTION TAKES SHAPE              
 TONIGHT WITH CONCERN SHIFTING TOWARD LAKE EFFECT SNOW FOR PORTIONS

 BOTH THE NAM AND GFS ARE IN RATHER GOOD AGREEMENT WITH THE                     
 1000-850MB FLOW WHICH IS RATHER PERSISTENT (360 DEGREES) FOR MOST OF           
 THE NIGHT.  TOWARD 09Z-12Z...FLOW BACKS A LITTLE MORE TAKING THE               
 BAND OFFSHORE BUT STILL TOUCHING THE M10 CORRIDOR IN HURON COUNTY.             
 INVERSION HEIGHTS CLIMB...PER BUFKIT PROFILES...FROM NEAR 850MB TO             
 BETWEEN 800-750MB WITH LAKE INDUCED CAPES CLIMBING TOWARD 300 J/KG             
 AND LAKE DELTA T/S INTO THE MIDDLE TEENS CELSIUS.  925MB CONVERGENCE           
 AND OMEGA FIELDS LOOK RATHER IMPRESSIVE ACROSS HURON...SANILAC AND             
 TOUCHING NORTHEAST ST CLAIR COUNTY OVERNIGHT SO ADDITIONAL SNOWFALL            
 IS EXPECTED.  LOCAL DECISION TREE SUGGESTS ANOTHER 2-4"/12HRS BUT              
 WITH THE BAND MOVING OFFSHORE...WILL CUT THOSE VALUES TO ANOTHER               
 1-3" AND MENTION BRIEF PERIODS OF HEAVY SNOW IN THE FORECAST/GRIDS.            
 WEATHER DOES QUIET DOWN ON TUESDAY WITH A COLD NORTHERLY FLOW AND              
 MOISTURE DECREASING.  THIS SHOULD ALLOW FOR SOME SUNNY BREAKS YET              
 THAT COULD HELP STEEPEN THE LOW LEVEL LAPSE RATES...AND WOULD NOT BE           
 SURPRISED TO SEE SOME LIGHT SNOW SHOWERS MOVING ACROSS THE CWA.                
 WILL KEEP THE LOW POPS FOR MOST AREAS AWAY FROM LAKE HURON...AS LAKE           
 BAND COULD STILL IMPACT THE M10 CORRIDOR IN HURON COUNTY.                      
 TEMPERATURES WILL BE QUITE CHILLY (OR SEASONABLE) TONIGHT AND                  
 TUESDAY WITH LOWS TONIGHT DROPPING BACK INTO THE TEENS.  ON TUESDAY            
 WITH 850MB TEMPS INTO THE NEGATIVE MID TEENS...WE WILL BE LUCKY TO             
 TOUCH 30F.

 THUS FAR AS 1040+ MB HIGH SETS UP OVER THE NORTHERN OHIO VALLEY                
 WEDNESDAY MORNING. HOWEVER...RELATIVELY WARM GROUND AND LACK OF                
 SIGNIFICANT SNOW DEPTH OVER MUCH OF SOUTHEAST MICHIGAN SHOULD FACTOR           
 IN. WENT FAIRLY CLOSE TO GFS MOS GUIDANCE...UPPER SINGLE NUMBERS TO

 WITH THE EXCEPTION OF WAYNE AND MONROE COUNTIES...WILL KEEP THE                
 WARNINGS GOING THROUGH THE REST OF THE MORNING. WARNINGS MAY BE ABLE           
 TO BE DOWNGRADED TO FREEZING DRIZZLE ADVISORIES LATE THIS MORNING.             
 HAVE RECEIVED SEVERAL REPORTS OF QUARTER TO HALF INCH ICE                      
 ACCUMULATIONS. WITH SURFACE TEMPS HOVERING IN THE LOWER 30S...THE              
 MOST SIGNIFICANT ACCUMULATIONS HAVE BEEN ON ELEVATED SURFACES LIKE             
 TREES AND POWER LINES. THE MAIN UPDATE TO THE HEADLINES THIS MORNING           
 WAS TO ADJUST FOR MORE FREEZING RAIN FROM FNT TO PHN AS A LITTLE               
 MORE WARM AIR ALOFT ADVECTED INTO THE FORECAST AREA THAN EARLIER               
 MODELS SUGGESTED. THE ONLY OTHER MAJOR ADJUSTMENTS WAS TO DOWNGRADE            
 MONROE AND WAYNE COUNTIES TO AN ADVISORY WITH CURRENT TEMPS NOW                
 ABOVE FREEZING AT DTW/DET/TTF/DUH. CURRENT TRENDS ALSO SUPPORT A               
 LITTLE LOWER SNOWFALL TOTALS ACROSS THE SAGINAW VALLEY AND THUMB               
 REGION.                                                                        
 LOW LEVEL COLD AIR ADVECTION AND DEEPER MOISTURE WILL WRAP BACK INTO           
 THE AREA LATE THIS AFTERNOON...TRANSITIONING ANY LINGERING DRIZZLE             
 TO LIGHT SNOW SHOWERS. WINDS WILL INCREASE TO THE 10 TO 20 MPH RANGE           
 BY THIS AFTERNOON...MAINLY NORTH OF M 59...WHICH MAY CAUSE SOME                
 ADDITIONAL PROBLEMS WITH TREES AND POWER LINES WEIGHTED DOWN WITH              
 ICE.                                                                           
 LONG TERM...MONDAY NIGHT THROUGH SUNDAY                                        
 BY MONDAY NIGHT THE LOW PRESSURE SYSTEM THAT BROUGHT A WINTER STORM            
 TO LOWER MICHIGAN WILL BE MOVING ACROSS THE NEW ENGLAND                        
 STATES...WITH A THERMAL TROUGH EXTENDING BACK ACROSS THE GREAT LAKES           
 REGION. THE NAM SEEMS TO HAVE A BETTER HANDLE ON SHORTWAVE ENERGY              
 DROPPING SOUTH OUT OF CANADA BASED ON WATER VAPOR IMAGERY AND                  
 REINFORCES THE UPPER LEVEL TROUGH OVER THE REGION. A NUMBER OF                 
 SHORTWAVES WILL MOVE OVER THE AREA MONDAY NIGHT AND TUESDAY. LIGHT             
 SNOW WILL CONTINUE INTO THE EVENING ON MONDAY BEFORE SNOW SHOWERS              
 BECOME PRIMARILY DRIVEN BY LAKE EFFECT AND DECREASE IN COVERAGE                
 OVERNIGHT. THE NAM12 DOES INDICATE LOW LEVEL CONVERGENCE OVER THE              
 THUMB...SHIFTING OFFSHORE BY LATE AT NIGHT. GIVEN THE SHIFTING                 
 TRAJECTORY FOR LAKE EFFECT SHOWERS ...WILL KEEP ACCUMULATIONS ON THE           
 LOW SIDE IN THE 1-3 INCH RANGE.                                                
 ON TUESDAY A WEAK 850MB TROUGH COMBINED WITH CONTINUED CYCLONIC FLOW           
 AT THE SURFACE SHOULD YIELD NUMEROUS SNOW SHOWERS ACROSS THE AREA.             
 THE SHOWERY NATURE OF THE SNOW WILL MAKE ACCUMULATIONS VARY                    
 WIDELY...BUT WILL EXPECT ACCUMULATIONS TO GENERALLY REMAIN AROUND AN           
 INCH OR LESS. INSTABILITY WILL PEAK TUESDAY EVENING AS THE UPPER               
 LEVEL COLD POOL MOVES SOUTH OVER THE AREA. MODEL SOUNDINGS OVER                
 SOUTHERN LAKE HURON INDICATE 850 J/KG OF LAKE INDUCED CAPE AND                 
 EQUILIBRIUM LEVELS OVER 14000 FEET. WILL EXPECT ANOTHER ROUND OF               
 SNOW SHOWERS AS THE 700MB TROUGH AXIS PASSES AND WILL CONTINUE TO              
 CARRY SOME ADDITIONAL LIGHT ACCUMULATIONS OVER THE THUMB INTO THE              
 OVERNIGHT HOURS.                                                               
 SKIES WILL START TO SCATTER OUT LATE TUESDAY NIGHT AS HIGH PRESSURE            
 BUILDS FROM THE SOUTHWEST. WILL GO SEVERAL DEGREES BELOW GUIDANCE              
 OVER OUR SOUTHWESTERN COUNTIES THAT ARE CLOSER TO THE SURFACE HIGH.            
 THE UPPER LEVEL RIDGE BUILDS OVER THE AREA ON WEDNESDAY WITH WARM              
 AIR ADVECTION BEGINNING AS SOUTHWESTERLY FLOW INCREASES ON THE WEST            
 SIDE OF THE SURFACE HIGH. MODELS ADVERTISE THE NEXT UPPER LEVEL                
 TROUGH TO QUICKLY APPROACH BY THE END OF THE WEEK WITH A NUMBER OF             
 WAVES MOVING OVER THE REGION IN THE THURSDAY NIGHT/FRIDAY TIME                 
 FRAME. THIS WILL BRING THE NEXT CHANCE OF LIGHT SNOW AND ANOTHER               
 COLD FRONT TO REINFORCE THE COLD AIR OVER THE REGION.

 THE MAIN CONCERN WITH THIS FORECAST UPDATE IS THE POTENTIAL FOR SNOW           
 THROUGH THIS AFTERNOON.                                                        
 WATER VAPOR IMAGERY AND RUC/NAM SHOWING A LONGWAVE TROUGH EXTENDING            
 FROM NORTHERN JAMES BAY SOUTHWEST INTO THE CENTRAL PLAINS THEN TO              
 NORTHERN BAJA. A RIDGE STRETCHES ACROSS THE PACIFIC NORTHWEST INTO             
 THE ALBERTA. A SHORTWAVE TROUGH EJECTED OUT OF THE TROUGH IS OVER              
 WESTERN U.P. AND WESTERN LAKE SUPERIOR. OTHERS UPSTREAM SHORTWAVES             
 ARE OVER KANSAS...ARIZONA AND WESTERN NORTH DAKOTA. SURFACE ANALYSIS           
 DEPICT A LOW OVER THE LOWER GREAT LAKES...A WEAK TROUGH EXTENDING              
 WEST TO NORTHERN IOWA...AND A RIDGE BLANKETING MUCH OF NORTHERN                
 PLAINS AND MANITOBA. AN 850MB THERMAL TROUGH (-20C) RUNS FROM                  
 EASTERN NORTH DAKOTA INTO WESTERN MANITOBA CAUSES TEMPERATURES OVER            
 WESTERN LAKE SUPERIOR TO BE AROUND -17C AND -15C OVER THE PART OF              
 THE LAKE. BOTH COOL ENOUGH TO PRODUCE LOW LEVEL INSTABILITY FOR LAKE           
 EFFECT SNOWS ENHANCEMENT. LOW LEVEL CONVERGENCE CONTINUE TO PRODUCE            
 HEAVY SNOW FALL OVER NORTHERN U.P. LOWEST INVERSION IS AROUND 3.5K             
 FEET. DEEP (SURFACE-850MB) MOISTURE IS 80 TO 85 PERCENT. PW IS IN              
 THE .25 TO .3 INCH RANGE WHICH IS FAIRLY DRY. THE HEAVIEST SNOW ARE            
 OCCURRING WHERE THE STRONGEST LAKE EFFECT SNOWS ARE OCCURRING OVER             
 NORTH CENTRAL U.P. AND EXTREME WESTERN SHORE OF THE FORECAST AREA.             
 THE LONGWAVE TROUGH WILL EDGE A LITTLE EAST BECOMING MORE CENTERED             
 OVER THE FORECAST AREA THIS AFTERNOON. THE LOWER GREAT LAKES LOW               
 WILL SHIFT TO NEW ENGLAND AS THE NORTHERN PLAINS RIDGE EDGES ONLY A            
 FEW MILES EAST. SURFACE WINDS WILL BACK A LITTLE MORE TO THE NORTH.            
 SYSTEM SNOW CONTINUE OVER THE FORECAST AREA MAINLY ALONG THE LAKE              
 MICHIGAN SHORE. KMQT-88D INDICATES LES BANDS DEVELOPING OVER                   
 MARQUETTE COUNTY AND WESTERN ALGER. SURFACE REPORTS ALSO INDICATE              
 HEAVY LES OVER EXTREMELY WESTERN U.P. RUC CONTINUES TO SHOW                    
 CONVERGENCE OVER CENTRAL LAKE SUPERIOR. 280K ISENTROPIC ANALYSIS               
 INDICATES MOSTLY DESCENT ACROSS THE AREA. MIXING RATIO ABOUT 1 G/KG            
 ACROSS THE SOUTHEAST PART OF THE FORECAST AREA. QUESTION WHETHER TO            
 EXTEND THE WARNING TO WESTERN ALGER COUNTY. AS THE WINDS BACK THIS             
 AFTERNOON THE BANDS WILL SHIFT THROUGH THE DAY AND DRY AIR WILL                
 ADVANCE INTO THE AREA FROM THE WEST WHICH SHOULD WEAKEN THE LES                
 ACROSS THE AREA. UP TO 7 INCHES OVER WILL FALL OVER WESTERN ALGER              
 COUNTY. SO WILL LEAVE IT WITH AN ADVISORY.                                     
 THIS EVENING THE SHORTWAVE WILL MOVE EAST. DRY AIR WILL MOVE INTO              
 THE AREA. SURFACE TEMPERATURE WILL REMAIN COOL ENOUGH TO KEEP LAKE             
 EFFECT SNOWS GOING. HOWEVER...THE DRYNESS WILL LIMIT SNOWFALL.

 THE BACK EDGE OF THE WIDESPREAD PRECIPITATION IS MOVING INTO SE MI             
 AS OF 11Z. BASED ON EXTRAPOLATION FROM RADAR...THE WIDESPREAD                  
 PRECIP WILL EXIT TO THE EAST OF THE TAF SITES SHORTLY AFTER 12Z.               
 BASED ON MODEL SOUNDINGS...WOULD EXPECT SOME DRIZZLE/FREEZING                  
 DRIZZLE IN THE WAKE OF THE WIDESPREAD PRECIPITATION. MBS WILL BE               
 INTO THE COLDER AIR AND MAY BE ABLE TO REMAIN LIGHT SNOW/FLURRIES              
 INTO THE AFTERNOON. DTW/DET HAVE BEEN HOVERING AROUND 33/34                    
 DEGREES FOR SEVERAL HOURS. THE TEMPERATURES AROUND DETROIT WILL                
 FALL TO THE FREEZING MARK OR SLIGHTLY LOWER BY 15Z AS THE COLDER               
 AIR STARTS FILTERING INTO SE MICHIGAN IN THE WAKE OF THE DEPARTING             
 SURFACE LOW OVER OHIO. SO THERE IS STILL A CHANCE FOR SOME                     
 FREEZING DRIZZLE AT DETROIT LATER THIS MORNING.                                
 WIDESPREAD IFR CEILINGS ARE EXPECTED TO PERSIST THROUGH THE

 THE 09Z SURFACE ANALYSIS SHOWS A 1009MB LOW NEAR INDIANAPOLIS...               
 WHICH IS ASSOCIATED WITH A MID LEVEL SHORT WAVE OVER THE MID                   
 MISSISSIPPI VALLEY. THIS WAVE IS EMBEDDED WITHIN THE SOUTHWEST FLOW            
 IN ADVANCE OF THE LONG WAVE TROUGH OVER THE NORTHERN AND CENTRAL               
 PLAINS. MID LEVEL FRONTAL FORCING WITHIN THE ENTRANCE REGION OF A              
 170KT UPPER LEVEL JET OVER SOUTHERN QUEBEC HAS PROVIDED WIDESPREAD             
 PRECIPITATION ACROSS SOUTHERN MICHIGAN OVERNIGHT. LOW LEVEL                    
 SOUTHERLY FLOW HAS ADVECTED A SIGNIFICANT ENOUGH WEDGE OF WARM AIR             
 ALOFT TO ALLOW MOST OF THE PRECIP ALONG AND SOUTH OF THE I 69                  
 CORRIDOR TO FALL AS FREEZING RAIN...WITH SNOW AND SLEET MAINLY                 
 CONFINED TO THE SAGINAW VALLEY AND NORTHERN THUMB.

 OBSERVATIONS THAT THE WEAK LOW LEVEL COLD AIR ADVECTION HAS NOT BEEN           
 ABLE TO OVERCOME THE LATENT HEAT RELEASE DUE TO FREEZING NEAR THE

 THE PRECIP NOW MOVING INTO SW LOWER MI...SUPPORTING THE FASTER GFS             
 AND RUC SOLUTIONS. BASED ON MODEL SOUNDINGS...PRECIP SHOULD                    
 TRANSITION TO FREEZING DRIZZLE BETWEEN 12Z AND 15Z AS MOISTURE

 FRONTOGENESIS IN THE 700-600MB LAYER ACROSS THE NORTHERN HALF OF

 REGION.                                                                        
 LOW LEVEL COLD AIR ADVECTION AND DEEPER MOISTURE WILL WRAP BACK INTO           
 THE AREA LATE THIS AFTERNOON...TRANSITIONING ANY LINGERING DRIZZLE             
 TO LIGHT SNOW SHOWERS. WINDS WILL INCREASE TO THE 10 TO 20 MPH RANGE           
 BY THIS AFTERNOON...MAINLY NORTH OF M 59...WHICH MAY CAUSE SOME                
 ADDITIONAL PROBLEMS WITH TREES AND POWER LINES WEIGHTED DOWN WITH              
 ICE.                                                                           
 LONG TERM...MONDAY NIGHT THROUGH SUNDAY                                        
 BY MONDAY NIGHT THE LOW PRESSURE SYSTEM THAT BROUGHT A WINTER STORM            
 TO LOWER MICHIGAN WILL BE MOVING ACROSS THE NEW ENGLAND                        
 STATES...WITH A THERMAL TROUGH EXTENDING BACK ACROSS THE GREAT LAKES           
 REGION. THE NAM SEEMS TO HAVE A BETTER HANDLE ON SHORTWAVE ENERGY              
 DROPPING SOUTH OUT OF CANADA BASED ON WATER VAPOR IMAGERY AND                  
 REINFORCES THE UPPER LEVEL TROUGH OVER THE REGION. A NUMBER OF                 
 SHORTWAVES WILL MOVE OVER THE AREA MONDAY NIGHT AND TUESDAY. LIGHT             
 SNOW WILL CONTINUE INTO THE EVENING ON MONDAY BEFORE SNOW SHOWERS              
 BECOME PRIMARILY DRIVEN BY LAKE EFFECT AND DECREASE IN COVERAGE                
 OVERNIGHT. THE NAM12 DOES INDICATE LOW LEVEL CONVERGENCE OVER THE              
 THUMB...SHIFTING OFFSHORE BY LATE AT NIGHT. GIVEN THE SHIFTING                 
 TRAJECTORY FOR LAKE EFFECT SHOWERS ...WILL KEEP ACCUMULATIONS ON THE           
 LOW SIDE IN THE 1-3 INCH RANGE.                                                
 ON TUESDAY A WEAK 850MB TROUGH COMBINED WITH CONTINUED CYCLONIC FLOW           
 AT THE SURFACE SHOULD YIELD NUMEROUS SNOW SHOWERS ACROSS THE AREA.             
 THE SHOWERY NATURE OF THE SNOW WILL MAKE ACCUMULATIONS VARY                    
 WIDELY...BUT WILL EXPECT ACCUMULATIONS TO GENERALLY REMAIN AROUND AN           
 INCH OR LESS. INSTABILITY WILL PEAK TUESDAY EVENING AS THE UPPER               
 LEVEL COLD POOL MOVES SOUTH OVER THE AREA. MODEL SOUNDINGS OVER                
 SOUTHERN LAKE HURON INDICATE 850 J/KG OF LAKE INDUCED CAPE AND                 
 EQUILIBRIUM LEVELS OVER 14000 FEET. WILL EXPECT ANOTHER ROUND OF               
 SNOW SHOWERS AS THE 700MB TROUGH AXIS PASSES AND WILL CONTINUE TO              
 CARRY SOME ADDITIONAL LIGHT ACCUMULATIONS OVER THE THUMB INTO THE              
 OVERNIGHT HOURS.

 BUILDS FROM THE SOUTHWEST. WILL GO SEVERAL DEGREES BELOW GUIDANCE              
 OVER OUR SOUTHWESTERN COUNTIES THAT ARE CLOSER TO THE SURFACE HIGH.            
 THE UPPER LEVEL RIDGE BUILDS OVER THE AREA ON WEDNESDAY WITH WARM              
 AIR ADVECTION BEGINNING AS SOUTHWESTERLY FLOW INCREASES ON THE WEST            
 SIDE OF THE SURFACE HIGH. MODELS ADVERTISE THE NEXT UPPER LEVEL                
 TROUGH TO QUICKLY APPROACH BY THE END OF THE WEEK WITH A NUMBER OF             
 WAVES MOVING OVER THE REGION IN THE THURSDAY NIGHT/FRIDAY TIME

 THE BACK EDGE OF THE WIDESPREAD PRECIPITATION IS MOVING INTO SE MI             
 AS OF 11Z. BASED ON EXTRAPOLATION FROM RADAR...THE WIDESPREAD                  
 PRECIP WILL EXIT TO THE EAST OF THE TAF SITES SHORTLY AFTER 12Z.               
 BASED ON MODEL SOUNDINGS...WOULD EXPECT SOME DRIZZLE/FREEZING                  
 DRIZZLE IN THE WAKE OF THE WIDESPREAD PRECIPITATION. MBS WILL BE               
 INTO THE COLDER AIR AND MAY BE ABLE TO REMAIN LIGHT SNOW/FLURRIES              
 INTO THE AFTERNOON. DTW/DET HAVE BEEN HOVERING AROUND 33/34                    
 DEGREES FOR SEVERAL HOURS. THE TEMPERATURES AROUND DETROIT WILL                
 FALL TO THE FREEZING MARK OR SLIGHTLY LOWER BY 15Z AS THE COLDER               
 AIR STARTS FILTERING INTO SE MICHIGAN IN THE WAKE OF THE DEPARTING             
 SURFACE LOW OVER OHIO. SO THERE IS STILL A CHANCE FOR SOME                     
 FREEZING DRIZZLE AT DETROIT LATER THIS MORNING.                                
 WIDESPREAD IFR CEILINGS ARE EXPECTED TO PERSIST THROUGH THE

 INTO THE REGION DURING THE AFTERNOON. CEILINGS WILL GRADUALLY                  
 RESPOND BY LIFTING TO THE VFR CATEGORY BY 20Z.

 THE 09Z SURFACE ANALYSIS SHOWS A 1009MB LOW NEAR INDIANAPOLIS...               
 WHICH IS ASSOCIATED WITH A MID LEVEL SHORT WAVE OVER THE MID                   
 MISSISSIPPI VALLEY. THIS WAVE IS EMBEDDED WITHIN THE SOUTHWEST FLOW            
 IN ADVANCE OF THE LONG WAVE TROUGH OVER THE NORTHERN AND CENTRAL               
 PLAINS. MID LEVEL FRONTAL FORCING WITHIN THE ENTRANCE REGION OF A              
 170KT UPPER LEVEL JET OVER SOUTHERN QUEBEC HAS PROVIDED WIDESPREAD             
 PRECIPITATION ACROSS SOUTHERN MICHIGAN OVERNIGHT. LOW LEVEL                    
 SOUTHERLY FLOW HAS ADVECTED A SIGNIFICANT ENOUGH WEDGE OF WARM AIR             
 ALOFT TO ALLOW MOST OF THE PRECIP ALONG AND SOUTH OF THE I 69                  
 CORRIDOR TO FALL AS FREEZING RAIN...WITH SNOW AND SLEET MAINLY                 
 CONFINED TO THE SAGINAW VALLEY AND NORTHERN THUMB.                             
 SURFACE OBSERVATIONS ACROSS SE MI SHOW THE FREEZING LINE EXTENDING             
 ALONG A DETROIT TO ADRIAN LINE. IT APPEARS FROM THE SURFACE                    
 OBSERVATIONS THAT THE WEAK LOW LEVEL COLD AIR ADVECTION HAS NOT BEEN           
 ABLE TO OVERCOME THE LATENT HEAT RELEASE DUE TO FREEZING NEAR THE              
 SURFACE. THUS TEMPS HAVE INCREASED A COUPLE DEGREES OVER THE LAST              
 TWO HOURS. IN FACT...MOST OF WAYNE AND MONROE COUNTIES ARE NOW                 
 ABOVE FREEZING. THE LATEST AREA RADAR DATA SHOWS THE BACK EDGE OF              
 THE PRECIP NOW MOVING INTO SW LOWER MI...SUPPORTING THE FASTER GFS             
 AND RUC SOLUTIONS. BASED ON MODEL SOUNDINGS...PRECIP SHOULD                    
 TRANSITION TO FREEZING DRIZZLE BETWEEN 12Z AND 15Z AS MOISTURE                 
 ABOVE -10 C IS STRIPPED AWAY. THE NAM HOWEVER SHOWS SOME LINGERING             
 FRONTOGENESIS IN THE 700-600MB LAYER ACROSS THE NORTHERN HALF OF               
 THE FORECAST AREA THROUGH 15Z WHICH CAN NOT BE RULED OUT GIVEN THE             
 STRENGTH OF THE UPPER JET.                                                     
 WITH THE EXCEPTION OF WAYNE AND MONROE COUNTIES...WILL KEEP THE                
 WARNINGS GOING THROUGH THE REST OF THE MORNING. WARNINGS MAY BE ABLE           
 TO BE DOWNGRADED TO FREEZING DRIZZLE ADVISORIES LATE THIS MORNING.             
 HAVE RECEIVED SEVERAL REPORTS OF QUARTER TO HALF INCH ICE                      
 ACCUMULATIONS. WITH SURFACE TEMPS HOVERING IN THE LOWER 30S...THE              
 MOST SIGNIFICANT ACCUMULATIONS HAVE BEEN ON ELEVATED SURFACES LIKE             
 TREES AND POWER LINES. THE MAIN UPDATE TO THE HEADLINES THIS MORNING           
 WAS TO ADJUST FOR MORE FREEZING RAIN FROM FNT TO PHN AS A LITTLE               
 MORE WARM AIR ALOFT ADVECTED INTO THE FORECAST AREA THAN EARLIER               
 MODELS SUGGESTED. THE ONLY OTHER MAJOR ADJUSTMENTS WAS TO DOWNGRADE            
 MONROE AND WAYNE COUNTIES TO AN ADVISORY WITH CURRENT TEMPS NOW                
 ABOVE FREEZING AT DTW/DET/TTF/DUH. CURRENT TRENDS ALSO SUPPORT A

 SURFACE OBSERVATIONS THAT THE LACK OF LOW LEVEL COLD AIR ADVECTION             
 HAS NOT BEEN ABLE TO OVERCOME THE LATENT HEAT RELEASE DUE TO                   
 FREEZING NEAR THE SURFACE. THUS TEMPS HAVE INCREASED A COUPLE                  
 DEGREES OVER THE LAST TWO HOURS. IN FACT...MOST OF WAYNE AND MONROE            
 COUNTIES ARE NOW ABOVE FREEZING. THE LATEST AREA RADAR DATA SHOWS              
 THE BACK EDGE OF THE PRECIP NOW MOVING INTO SW LOWER MI...SUPPORTING           
 THE FASTER GFS AND RUC SOLUTIONS. BASED ON MODEL SOUNDINGS...PRECIP            
 SHOULD TRANSITION TO FREEZING DRIZZLE BETWEEN 12Z AND 15Z AS                   
 MOISTURE ABOVE -10 C IS STRIPPED AWAY. THE NAM HOWEVER SHOWS SOME              
 LINGERING FRONTOGENESIS IN THE 700-600MB LAYER ACROSS THE NORTHERN             
 HALF OF THE FORECAST AREA THROUGH 15Z WHICH CAN NOT BE RULED OUT               
 GIVEN THE STRENGTH OF THE UPPER JET.                                           
 WITH THE EXCEPTION OF WAYNE AND MONROE COUNTIES...WILL KEEP THE                
 WARNINGS GOING THROUGH THE REST OF THE MORNING. WARNINGS MAY BE ABLE           
 TO BE DOWNGRADED TO FREEZING DRIZZLE ADVISORIES LATE THIS MORNING.             
 HAVE RECEIVED SEVERAL REPORTS OF QUARTER TO HALF INCH ICE                      
 ACCUMULATIONS. WITH SURFACE TEMPS HOVERING IN THE LOWER 30S...THE              
 MOST SIGNIFICANT ACCUMULATIONS HAVE BEEN ON ELEVATED SURFACES LIKE             
 TREES AND POWER LINES. THE MAIN UPDATE TO THE HEADLINES THIS MORNING           
 WAS TO ADJUST FOR MORE FREEZING RAIN FROM FNT TO PHN AS A LITTLE               
 MORE WARM AIR ALOFT ADVECTED INTO THE FORECAST AREA THAN EARLIER               
 MODELS SUGGESTED. THE ONLY OTHER MAJOR ADJUSTMENTS WAS TO DOWNGRADE            
 MONROE AND WAYNE COUNTIES TO AN ADVISORY WITH CURRENT TEMPS NOW                
 ABOVE FREEZING AT DTW/DET/TTF/DUH. CURRENT TRENDS ALSO SUPPORT A               
 LITTLE LOWER SNOWFALL TOTALS ACROSS THE SAGINAW VALLEY AND THUMB               
 REGION.                                                                        
 LOW LEVEL COLD AIR ADVECTION AND DEEPER MOISTURE WILL WRAP BACK INTO           
 THE AREA LATE THIS AFTERNOON...TRANSITIONING ANY LINGERING DRIZZLE             
 TO LIGHT SNOW SHOWERS. WINDS WILL INCREASE TO THE 10 TO 20 MPH RANGE           
 BY THIS AFTERNOON...MAINLY NORTH OF M 59...WHICH MAY CAUSE SOME                
 ADDITIONAL PROBLEMS WITH TREES AND POWER LINES WEIGHTED DOWN WITH              
 ICE.

 TO LOWER MICHIGAN WILL BE MOVING ACROSS THE NEW ENGLAND                        
 STATES...WITH A THERMAL TROUGH EXTENDING BACK ACROSS THE GREAT LAKES           
 REGION. THE NAM SEEMS TO HAVE A BETTER HANDLE ON SHORTWAVE ENERGY              
 DROPPING SOUTH OUT OF CANADA BASED ON WATER VAPOR IMAGERY AND                  
 REINFORCES THE UPPER LEVEL TROUGH OVER THE REGION. A NUMBER OF                 
 SHORTWAVES WILL MOVE OVER THE AREA MONDAY NIGHT AND TUESDAY. LIGHT             
 SNOW WILL CONTINUE INTO THE EVENING ON MONDAY BEFORE SNOW SHOWERS              
 BECOME PRIMARILY DRIVEN BY LAKE EFFECT AND DECREASE IN COVERAGE                
 OVERNIGHT. THE NAM12 DOES INDICATE LOW LEVEL CONVERGENCE OVER THE              
 THUMB...SHIFTING OFFSHORE BY LATE AT NIGHT. GIVEN THE SHIFTING                 
 TRAJECTORY FOR LAKE EFFECT SHOWERS ...WILL KEEP ACCUMULATIONS ON THE           
 LOW SIDE IN THE 1-3 INCH RANGE.                                                
 ON TUESDAY A WEAK 850MB TROUGH COMBINED WITH CONTINUED CYCLONIC FLOW           
 AT THE SURFACE SHOULD YIELD NUMEROUS SNOW SHOWERS ACROSS THE AREA.             
 THE SHOWERY NATURE OF THE SNOW WILL MAKE ACCUMULATIONS VARY                    
 WIDELY...BUT WILL EXPECT ACCUMULATIONS TO GENERALLY REMAIN AROUND AN           
 INCH OR LESS. INSTABILITY WILL PEAK TUESDAY EVENING AS THE UPPER               
 LEVEL COLD POOL MOVES SOUTH OVER THE AREA. MODEL SOUNDINGS OVER                
 SOUTHERN LAKE HURON INDICATE 850 J/KG OF LAKE INDUCED CAPE AND                 
 EQUILIBRIUM LEVELS OVER 14000 FEET. WILL EXPECT ANOTHER ROUND OF               
 SNOW SHOWERS AS THE 700MB TROUGH AXIS PASSES AND WILL CONTINUE TO              
 CARRY SOME ADDITIONAL LIGHT ACCUMULATIONS OVER THE THUMB INTO THE              
 OVERNIGHT HOURS.                                                               
 SKIES WILL START TO SCATTER OUT LATE TUESDAY NIGHT AS HIGH PRESSURE            
 BUILDS FROM THE SOUTHWEST. WILL GO SEVERAL DEGREES BELOW GUIDANCE              
 OVER OUR SOUTHWESTERN COUNTIES THAT ARE CLOSER TO THE SURFACE HIGH.            
 THE UPPER LEVEL RIDGE BUILDS OVER THE AREA ON WEDNESDAY WITH WARM              
 AIR ADVECTION BEGINNING AS SOUTHWESTERLY FLOW INCREASES ON THE WEST            
 SIDE OF THE SURFACE HIGH. MODELS ADVERTISE THE NEXT UPPER LEVEL                
 TROUGH TO QUICKLY APPROACH BY THE END OF THE WEEK WITH A NUMBER OF             
 WAVES MOVING OVER THE REGION IN THE THURSDAY NIGHT/FRIDAY TIME                 
 FRAME. THIS WILL BRING THE NEXT CHANCE OF LIGHT SNOW AND ANOTHER               
 COLD FRONT TO REINFORCE THE COLD AIR OVER THE REGION.

 TAKING A LOOK AT THE WATER VAPOR IMAGERY THIS MORNING...THE BULK OF            
 MOISTURE FROM THE SOUTHWEST HAS BEGUN TO INVADE THE UPPER                      
 PENINSULA.  THE CENTER OF THE SURFACE LOW WAS LOCATED ACROSS                   
 SOUTHERN INDIANA...AS WAS CONTINUING TO TRACK NORTHEASTWARD.                   
 COMPARING THIS POSITION TO THE MODEL GUIDANCE OF 24 HOURS AGO...IT             
 LOOKS LIKE THE NAM HAD A BETTER HANDLE ON ITS POSITION THAN THE                
 FURTHER EASTWARD GFS.  EVEN BETTER THOUGH WAS PROBABLY THE CANADIAN            
 MODEL WHICH HAD ITS 12Z MON POSITION ACROSS SOUTHWESTERN OHIO.  IN             
 GENERAL...THE CANADIAN MODEL SEEMS TO BE DOING BETTER THAN MANY OF             
 THE OTHER MODELS CURRENTLY...AND THROUGH MUCH OF THE FORECAST PERIOD.          
 ACROSS THE WESTERN HALF OF THE NATION...HIGH PRESSURE DOMINATED MUCH           
 OF THE AREA.  THIS WAS RESULTING IN A LACK OF PRECIPITATION WEST OF            
 A LINE FROM NORTHERN MINNESOTA THROUGH NEBRASKA AND INTO WESTERN               
 TEXAS.  HOWEVER...EAST OF THIS LINE THE NATION IS BEING AFFECTED BY            
 THE LARGE STORM SYSTEM CENTERED TO OUR SOUTH.  MUCH OF THIS MID                
 JANUARY PRECIPITATION IS FALLING AS RAIN ACROSS THE LOWER 48...WITH            
 A CHANGEOVER TO SNOW ACROSS SOUTHERN MICHIGAN AND NORTHERN                     
 ILLINOIS...AND THEN ALONG THE BACK EDGE OF THE PRECIPITATION BAND              
 FURTHER SOUTH.                                                                 
 CLOSER TO HOME...THE EASTERN HALF OF THE FORECAST AREA CONTINUES TO            
 SEE NEARLY CONSTANT MODERATE SNOW.  THIS AREA IS ALSO IN A FAVORABLE           
 LOCATION...IN THE RIGHT REAR QUADRANT OF AN EXITING 130KT JET AS               
 SHOWN ON THE RUC.  THE ACTUAL JET MAX OF 170KT IS LOCATION ACROSS              
 SOUTHERN QUEBEC.  THE 500MB TROUGH IS ALSO NEARING THE                         
 REGION...CURRENTLY CENTERED ACROSS NORTHEASTERN NORTH DAKOTA THROUGH           
 NORTHEASTERN COLORADO...ATTEMPTING TO PUSH THIS SYSTEM OUT OF THE              
 CENTRAL AND SOUTHERN PLAINS.  SURFACE WINDS CURRENTLY 10 TO 30                 
 DEGREES SHOULD BECOME MORE NORTHWARD AFTER 18Z 360 TO 20                       
 DEGREES...AND THEN BACK SLIGHTLY MORE NORTHWESTERLY AROUND AND AFTER           
 06Z TUESDAY TO 320 TO 350 DEGREES...LIMITING A GOOD FETCH FOR LAKE             
 EFFECT ACROSS THE EASTERN THIRD OF THE LAKE SUPERIOR                           
 SHORELINE...WITH THE FOCUS THEN SHIFTING TO THE CENTRAL AND EASTERN            
 UPPER PENINSULA.  WITH THAT SAID...NO CHANGES WERE MADE TO THE                 
 CURRENT WARNINGS AND ADVISORIES.  ALREADY HAVE ABOUT 5 INCHES AT WFO           
 MQT SINCE THE LAKE EFFECT SNOW WARNING WENT INTO EFFECT...SO IT                
 LOOKS LIKE IT SHOULD PAN OUT.                                                  
 OTHERWISE...NEARLY STEADY TEMPERATURES FIGURED TODAY.  WARMED UP               
 OVERNIGHT TEMPERATURES TONIGHT ACROSS THE WEST CENTRAL PORTIONS OF             
 THE CWA...GIVEN WARMER GUIDANCE NUMBERS FROM THE MODELS AND THE FACT           
 THAT PLENTY OF CLOUDS SHOULD STILL BE AROUND AT THAT TIME.                     
 FOR TUESDAY AFTERNOON...COLDEST AIR WILL BE OVERHEAD ACROSS THE                
 EASTERN HALF OF THE CWA WITH 850MB TEMPS OF -20 TO -22C.  WITH THIS            
 AND NORTHWESTERLY SURFACE WINDS...CLOUDS SHOULD HAVE A DIFFICULT               
 TIME EXITING THIS AREA.  SO...HAVE PLACED THE WARMEST TEMPERATURES             
 ACROSS THE LAKE MICHIGAN SHORELINE FOR TUESDAY.                                
 TUESDAY NIGHT IS EXPECTED TO BE THE COLDEST NIGHT IN THE NEAR                  
 FUTURE...WITH GOOD RADIATIONAL COOLING ANTICIPATED PARTICULARLY                
 ACROSS THE SW PENINSULA.  SO...STAYED ON THE COOLER SIDE OF GUIDANCE           
 GENERALLY SIDING WITH THE MET HERE.                                            
 FROM THE 500MB TROUGH CURRENTLY STRETCHING FROM NORTHEAST TO                   
 SOUTHWEST ACROSS THE NATIONS MIDSECTION...A CUT OFF LOW IS EXPECTED            
 TO REMAIN.  THIS LOW SHOULD DEEPEN OVER THE FOUR CORNERS REGION                
 THROUGH MIDWEEK...BEFORE EJECTING NORTHEASTWARD TOWARDS THE GREAT              
 LAKES.  THIS WILL RESULT IN ONLY A SHORT BREAK IN PRECIPITATION FOR            
 OUR AREA.  HAVE A BRIEF DRY PERIOD GENERALLY FROM TUESDAY NIGH                 
 THOUGH WEDNESDAY.  IF THE QUICKER AND SLIGHTLY MORE FAVORED CANADIAN           
 AND UKMET PAN OUT...WE MAY NEED TO ADD POPS BACK A LITTLE QUICKER              
 THAN PREVIOUSLY ANTICIPATED.                                                   
 AS FOR TEMPERATURES WEDNESDAY NIGHT...DISCREPANCIES AND FORECASTER             
 CONFIDENCE BEGINS TO COME INTO PLAY.  SO...FEW CHANCES WERE MADE               
 BEYOND THIS POINT.  STILL...FOLLOWING A SLIGHTLY CANADIAN AND UKMET            
 QUICKER SOLUTION...OUR LATEST WIND GRIDS DO REFLECT A SLIGHTLY

 SUPPORTING THE MID LEVEL WAVE TO STRONG MOISTURE TRANSPORT AND                 
 LOW STATIC STABILITY. THERE IS EVEN SOME CONVECTIVE INSTABILITY                
 INDICATED IN MODEL CROSS SECTIONS NEAR THE OHIO BORDER THROUGH THE

 BORDER SINCE ABOUT 01Z AND SPREADING NORTHWARD ON STRONG MOISTURE              
 TRANSPORT/THETA-E ADVECTION. THIS WILL TRANSITION TO STRONG                    
 DYNAMIC FORCING IN THE MIDST OF THE MID LEVEL TROWAL AS THE                    
 SURFACE LOW TRACKS TO OUR SOUTH AND EAST. THE STRONG FORCING AND               
 HIGH PRECIPITATION RATES WILL KEEP PRECIPITATION TYPE ON THE COLD              
 END OF THE SPECTRUM IN CENTRAL AND SOUTH LOCATIONS WHERE THE                   
 THERMAL PROFILE ALLOWS MIXED PRECIPITATION. ALL SNOW IN THE TRI                
 CITIES AND THUMB LOOKS GOOD WITH BRIEF MIXES OF SLEET. PLAN TO KEEP            
 ACCUMULATIONS OF SNOW AND ICE AS IS WITH THE 00Z MODELS COMING IN              
 MORE IN LINE WITH RESPECT TO QPF. THE ONLY LIMITING FACTOR FOR                 
 ICING WILL BE NEAR THE OHIO BORDER WHERE TEMPERATURES WILL HOVER               
 AROUND THE FREEZING MARK NEAR THE LAKE ERIE SHORELINE, AT LEAST

 SHORT TERM...TONIGHT AND MONDAY                                                
 NOW THAT THE ROUND OF MIXED PRECIPITATION FROM THIS MORNING HAS                
 ENDED...THE ATTENTION TURNS TO A GATHERING STORM OVER THE SOUTHERN             
 PLAINS. A STRONG SHORTWAVE THAT HAS LIFTED AROUND THE BASE OF THE              
 MEAN WESTERN CONUS TROUGH INTO THE SOUTHERN/CENTRAL PLAINS WILL BE             
 RESPONSIBLE FOR AN EXPANDING AREA OF PRECIPITATION...WHICH WILL                
 PROGRESS QUICKLY INTO THE AREA TOWARD MIDNIGHT. THIS FEATURE HAS               
 ALREADY BEEN RESPONSIBLE FOR SIGNIFICANT FREEZING RAIN/SLEET OVER              
 PORTIONS OF THE SOUTHERN PLAINS TODAY...WITH QUITE A BIT OF THUNDER            
 OVER OKLAHOMA/NORTHERN TEXAS.                                                  
 12Z NAM HAS EXPANDED UPON "ITS" 06Z IDEA OF THROWING MORE MOISTURE             
 AND HENCE QPF INTO THE AREA LATE TONIGHT. THIS LEADS TO WIDESPREAD             
 75 TO NEAR 1.00 INCH TOTALS. IT ALSO BRINGS IN A STRONG ELEVATED               
 WARM LAYER WITH THIS SURGE...LEADING TO MORE FREEZING RAIN/SLEET.              
 GFS REMAINS MORE SUBDUED IN BOTH RESPECTS. THESE DIFFERENCES DO POSE           
 PROBLEMS IN BOTH PRECIPITATION TYPE/AMOUNT FORECASTS...WITH THE NAM            
 SUPPORTING SOLID WARNING CRITERIA CWA-WIDE...AND GFS NOT.                      
 NGM/GEM/LOCALWRF AND VARIOUS EXPERIMENTAL FSL RUC RUNS SUGGEST A               
 BLEND OF THE TWO...WHICH IS NOT TOO SURPRISING. THESE SOLUTIONS                
 SUPPORT WARNING CRITERIA FOR MOST COUNTIES...WITH ONLY A FEW ON THE            
 EDGE. IT IS WORTH NOTING THAT NAM WAS FAR SUPERIOR WITH THE QUARTER            
 INCH BAND OF SNOW/SLEET THAT MOVED THROUGH THE AREA THIS MORNING.              
 GIVEN THIS FACT...AND RADAR TRENDS THROUGH THE PLAINS/MISSISSIPPI              
 VALLEY SO FAR...FEEL THAT GIVING A BIT MORE WEIGHT TO THE NAM IS               
 PROBABLY THE WAY TO GO...SO AN UPGRADE TO VARIOUS WARNINGS SEEMS               
 REASONABLE. EVEN IF A 50/50 COMPROMISE IS USED...MOST COUNTIES                 
 SHOULD RECEIVE ENOUGH SNOW AND/OR ICE ACCUMULATIONS TO SUPPORT THE             
 WARNING CRITERIA.                                                              
 SO...THE PLAN IS TO GO WITH A HEAVY SNOW WARNING ACROSS THE SAGINAW            
 VALLEY AND NORTHERN THUMB WHERE PRECIPITATION WILL BE PRETTY MUCH              
 ALL SNOW. COUNTIES ALONG I-69 WILL HAVE A WINTER STORM WARNING FOR             
 THE MIXTURE OF SNOW/SLEET SOME FREEZING RAIN. MEANWHILE...THE MAIN             
 HAZARD FOR THE "M-59" COUNTIES SOUTH WILL BE FREEZING RAIN...SO AN             
 ICE STORM WARNING FITS WELL. THERE MAY BE SOME LOCATIONS NEAR LAKES            
 ERIE/ST CLAIR THAT WILL HOVER AT/ABOVE FREEZING...BUT MOST AREAS               
 SHOULD RECEIVED A PROLONGED FREEZING RAIN EVENT.                               
 ALMOST ALL THE THE PRECIPITATION FALLS BETWEEN 04Z-12Z...WITH THE              
 TAIL END OF THE EVENT LINGERING INTO MONDAY MORNING. WARNINGS WILL             
 BE TIMED ACCORDINGLY.

 START AROUND 5-6KFT MONDAY AFTERNOON AND LIFT TO 8-9KFT MONDAY                 
 NIGHT.  THERE WILL BE AMPLE MOISTURE WITHIN AND ABOVE THE CONVECTIVE           
 LAYER TO SUPPORT LAKE-EFFECT SNOWS.  THE PRIMARY LIMITING FACTOR               
 WILL BE THAT THE WINDS ARE BACKING THROUGH THE TIME PERIOD...HELPING           
 TO DISTRIBUTE THE SNOWFALL COVERAGE AND REDUCING THE CHANCES THAT              
 ANY ONE LOCATION SEES A PROLONGED PERIOD OF SNOW.  BY TUESDAY                  
 MORNING THE CONVECTIVE LAYER FLOW SHOULD BE NORTHWESTERLY...KEEPING            
 THE THUMB OUT OF THE SITES.                                                    
 THE ATMOSPHERE WILL SETTLE DOWN ACROSS THE REGION FOR THE REMAINING            
 PORTION OF THE FORECAST.  WEAK RIDGING IN THE PRESENCE OF A GENERAL            
 LOWERING OF HEIGHTS ALOFT WILL SET THE STAGE FOR SEASONABLE                    
 CONDITIONS.  THE NEXT SHOT AT SNOW HOLDS OFF UNTIL THE END OF                  
 WEEK...ONCE THE LONG WAVE TROUGHS TRIES TO RE-ESTABLISH ACROSS

 SLEET WILL DEVELOP ALONG THE I-94 CORRIDOR DURING THE NEXT 1 TO 2              
 HRS. A SAMPLING OF RUC FCST SOUNDINGS TAKEN ALONG I-94 FROM AZO EAST           
 TO JXN SUGGESTS THAT PCPN DOWN THERE MAY BEGIN AS A PERIOD OF SLEET            
 (AND PERHAPS SNOW) BEFORE WARMER AIR ALOFT (FROM AROUND 750 TO 900

 NOW THAT THE ROUND OF MIXED PRECIPITATION FROM THIS MORNING HAS                
 ENDED...THE ATTENTION TURNS TO A GATHERING STORM OVER THE SOUTHERN             
 PLAINS. A STRONG SHORTWAVE THAT HAS LIFTED AROUND THE BASE OF THE              
 MEAN WESTERN CONUS TROUGH INTO THE SOUTHERN/CENTRAL PLAINS WILL BE             
 RESPONSIBLE FOR AN EXPANDING AREA OF PRECIPITATION...WHICH WILL                
 PROGRESS QUICKLY INTO THE AREA TOWARD MIDNIGHT. THIS FEATURE HAS               
 ALREADY BEEN RESPONSIBLE FOR SIGNIFICANT FREEZING RAIN/SLEET OVER              
 PORTIONS OF THE SOUTHERN PLAINS TODAY...WITH QUITE A BIT OF THUNDER            
 OVER OKLAHOMA/NORTHERN TEXAS.                                                  
 12Z NAM HAS EXPANDED UPON "ITS" 06Z IDEA OF THROWING MORE MOISTURE             
 AND HENCE QPF INTO THE AREA LATE TONIGHT. THIS LEADS TO WIDESPREAD             
 75 TO NEAR 1.00 INCH TOTALS. IT ALSO BRINGS IN A STRONG ELEVATED               
 WARM LAYER WITH THIS SURGE...LEADING TO MORE FREEZING RAIN/SLEET.              
 GFS REMAINS MORE SUBDUED IN BOTH RESPECTS. THESE DIFFERENCES DO POSE           
 PROBLEMS IN BOTH PRECIPITATION TYPE/AMOUNT FORECASTS...WITH THE NAM            
 SUPPORTING SOLID WARNING CRITERIA CWA-WIDE...AND GFS NOT.                      
 NGM/GEM/LOCALWRF AND VARIOUS EXPERIMENTAL FSL RUC RUNS SUGGEST A               
 BLEND OF THE TWO...WHICH IS NOT TOO SURPRISING. THESE SOLUTIONS                
 SUPPORT WARNING CRITERIA FOR MOST COUNTIES...WITH ONLY A FEW ON THE            
 EDGE. IT IS WORTH NOTING THAT NAM WAS FAR SUPERIOR WITH THE QUARTER            
 INCH BAND OF SNOW/SLEET THAT MOVED THROUGH THE AREA THIS MORNING.              
 GIVEN THIS FACT...AND RADAR TRENDS THROUGH THE PLAINS/MISSISSIPPI              
 VALLEY SO FAR...FEEL THAT GIVING A BIT MORE WEIGHT TO THE NAM IS               
 PROBABLY THE WAY TO GO...SO AN UPGRADE TO VARIOUS WARNINGS SEEMS               
 REASONABLE. EVEN IF A 50/50 COMPROMISE IS USED...MOST COUNTIES                 
 SHOULD RECEIVE ENOUGH SNOW AND/OR ICE ACCUMULATIONS TO SUPPORT THE             
 WARNING CRITERIA.                                                              
 SO...THE PLAN IS TO GO WITH A HEAVY SNOW WARNING ACROSS THE SAGINAW            
 VALLEY AND NORTHERN THUMB WHERE PRECIPITATION WILL BE PRETTY MUCH              
 ALL SNOW. COUNTIES ALONG I-69 WILL HAVE A WINTER STORM WARNING FOR             
 THE MIXTURE OF SNOW/SLEET SOME FREEZING RAIN. MEANWHILE...THE MAIN             
 HAZARD FOR THE "M-59" COUNTIES SOUTH WILL BE FREEZING RAIN...SO AN             
 ICE STORM WARNING FITS WELL. THERE MAY BE SOME LOCATIONS NEAR LAKES            
 ERIE/ST CLAIR THAT WILL HOVER AT/ABOVE FREEZING...BUT MOST AREAS               
 SHOULD RECEIVED A PROLONGED FREEZING RAIN EVENT.                               
 ALMOST ALL THE THE PRECIPITATION FALLS BETWEEN 04Z-12Z...WITH THE              
 TAIL END OF THE EVENT LINGERING INTO MONDAY MORNING. WARNINGS WILL             
 BE TIMED ACCORDINGLY.

 NIGHT.  THERE WILL BE AMPLE MOISTURE WITHIN AND ABOVE THE CONVECTIVE           
 LAYER TO SUPPORT LAKE-EFFECT SNOWS.  THE PRIMARY LIMITING FACTOR               
 WILL BE THAT THE WINDS ARE BACKING THROUGH THE TIME PERIOD...HELPING

 .SHORT TERM...TONIGHT AND MONDAY                                               
 NOW THAT THE ROUND OF MIXED PRECIPITATION FROM THIS MORNING HAS                
 ENDED...THE ATTENTION TURNS TO A GATHERING STORM OVER THE SOUTHERN             
 PLAINS. A STRONG SHORTWAVE THAT HAS LIFTED AROUND THE BASE OF THE              
 MEAN WESTERN CONUS TROUGH INTO THE SOUTHERN/CENTRAL PLAINS WILL BE             
 RESPONSIBLE FOR AN EXPANDING AREA OF PRECIPITATION...WHICH WILL                
 PROGRESS QUICKLY INTO THE AREA TOWARD MIDNIGHT. THIS FEATURE HAS               
 ALREADY BEEN RESPONSIBLE FOR SIGNIFICANT FREEZING RAIN/SLEET OVER              
 PORTIONS OF THE SOUTHERN PLAINS TODAY...WITH QUITE A BIT OF THUNDER            
 OVER OKLAHOMA/NORTHERN TEXAS.                                                  
 12Z NAM HAS EXPANDED UPON "ITS" 06Z IDEA OF THROWING MORE MOISTURE             
 AND HENCE QPF INTO THE AREA LATE TONIGHT. THIS LEADS TO WIDESPREAD             
 .75 TO NEAR 1.00 INCH TOTALS. IT ALSO BRINGS IN A STRONG ELEVATED              
 WARM LAYER WITH THIS SURGE...LEADING TO MORE FREEZING RAIN/SLEET.              
 GFS REMAINS MORE SUBDUED IN BOTH RESPECTS. THESE DIFFERENCES DO POSE           
 PROBLEMS IN BOTH PRECIPITATION TYPE/AMOUNT FORECASTS...WITH THE NAM            
 SUPPORTING SOLID WARNING CRITERIA CWA-WIDE...AND GFS NOT.                      
 NGM/GEM/LOCALWRF AND VARIOUS EXPERIMENTAL FSL RUC RUNS SUGGEST A               
 BLEND OF THE TWO...WHICH IS NOT TOO SURPRISING. THESE SOLUTIONS                
 SUPPORT WARNING CRITERIA FOR MOST COUNTIES...WITH ONLY A FEW ON THE            
 EDGE. IT IS WORTH NOTING THAT NAM WAS FAR SUPERIOR WITH THE QUARTER            
 INCH BAND OF SNOW/SLEET THAT MOVED THROUGH THE AREA THIS MORNING.              
 GIVEN THIS FACT...AND RADAR TRENDS THROUGH THE PLAINS/MISSISSIPPI              
 VALLEY SO FAR...FEEL THAT GIVING A BIT MORE WEIGHT TO THE NAM IS               
 PROBABLY THE WAY TO GO...SO AN UPGRADE TO VARIOUS WARNINGS SEEMS               
 REASONABLE. EVEN IF A 50/50 COMPROMISE IS USED...MOST COUNTIES                 
 SHOULD RECEIVE ENOUGH SNOW AND/OR ICE ACCUMULATIONS TO SUPPORT THE             
 WARNING CRITERIA.                                                              
 SO...THE PLAN IS TO GO WITH A HEAVY SNOW WARNING ACROSS THE SAGINAW            
 VALLEY AND NORTHERN THUMB WHERE PRECIPITATION WILL BE PRETTY MUCH              
 ALL SNOW. COUNTIES ALONG I-69 WILL HAVE A WINTER STORM WARNING FOR             
 THE MIXTURE OF SNOW/SLEET SOME FREEZING RAIN. MEANWHILE...THE MAIN             
 HAZARD FOR THE "M-59" COUNTIES SOUTH WILL BE FREEZING RAIN...SO AN             
 ICE STORM WARNING FITS WELL. THERE MAY BE SOME LOCATIONS NEAR LAKES            
 ERIE/ST CLAIR THAT WILL HOVER AT/ABOVE FREEZING...BUT MOST AREAS               
 SHOULD RECEIVED A PROLONGED FREEZING RAIN EVENT.                               
 ALMOST ALL THE THE PRECIPITATION FALLS BETWEEN 04Z-12Z...WITH THE              
 TAIL END OF THE EVENT LINGERING INTO MONDAY MORNING. WARNINGS WILL             
 BE TIMED ACCORDINGLY.

 START AROUND 5-6KFT MONDAY AFTERNOON AND LIFT TO 8-9KFT MONDAY                 
 NIGHT.  THERE WILL BE AMPLE MOISTURE WITHIN AND ABOVE THE CONVECTIVE           
 LAYER TO SUPPORT LAKE-EFFECT SNOWS.  THE PRIMARY LIMITING FACTOR               
 WILL BE THAT THE WINDS ARE BACKING THROUGH THE TIME PERIOD...HELPING           
 TO DISTRIBUTE THE SNOWFALL COVERAGE AND REDUCING THE CHANCES THAT              
 ANY ONE LOCATION SEES A PROLONGED PERIOD OF SNOW.  BY TUESDAY                  
 MORNING THE CONVECTIVE LAYER FLOW SHOULD BE NORTHWESTERLY...KEEPING

 THE ATMOSPHERE WILL SETTLE DOWN ACROSS THE REGION FOR THE REMAINING            
 PORTION OF THE FORECAST.  WEAK RIDGING IN THE PRESENCE OF A GENERAL            
 LOWERING OF HEIGHTS ALOFT WILL SET THE STAGE FOR SEASONABLE                    
 CONDITIONS.  THE NEXT SHOT AT SNOW HOLDS OFF UNTIL THE END OF

 NORTHWESTERN JAMES BAY.  THIS IS MUCH COOLER THAN OUR -12 TO -15C              
 OVER THE UPPER PENINSULA.  STILL THIS WILL BE ENOUGH FOR LIGHT LAKE            
 EFFECT PRECIPITATION TODAY...GENERALLY AROUND AN INCH OR LESS.                 
 THE RELATIVELY DRY COLD FRONT WILL CONTINUE TO SLOWLY SWEEP ACROSS             
 THE CWA THIS MORNING...WITH ENHANCED LOW LEVEL CONVERGENCE AND                 
 VEERING WINDS AND INVERSION HEIGHTS BETWEEN 3 AND 4FT.  THE BEST               
 QVECTOR CONVERGENCE IS REMAINING WELL TO THE NORTH...SO CONDITIONS             
 WILL BE MARGINAL FOR MORE THEN LIGHT LES AS PREVIOUSLY                         
 STATED...AROUND AN INCH OR LESS. LOOKING AT THE IR SATELLITE...BANDS           
 ARE BEGINNING TO FORM ACROSS THE NORTHERN HALF OF LAKE SUPERIOR.               
 THE SHOW SHOWERS SHOULD DIMINISH AND SPREAD OUT ACROSS THE AREA LATE           
 IN THE AFTERNOON AS HIGH PRESSURE SINKS SOUTHEASTWARD FROM CENTRAL             
 SASKATCHEWAN.                                                                  
 SOME VARIABILITY STILL REMAINS WITH THE FORECAST TRACK OF THE

 DIFFICULT TO PIN DOWN ON THE SURFACE MAP AS IT IS MORE                         
 ELONGATED...STRETCHING ACROSS SOUTHERN TEXAS...NORTHEASTWARD ALONG             
 THE MISSISSIPPI RIVER VALLEY AND INTO THE SOUTHERN OHIO VALLEY.  BY            
 12Z MONDAY...MODELS ARE HAVING A TOUGH TIME FIGURING OUT WHERE THE             
 CENTER OF LOW PRESSURE WILL BE LOCATED.  IT WILL BE SOMEWHERE IN THE           
 CENTRAL TO NORTHERN OHIO VALLEY...EITHER ACROSS NE OHIO (00Z NAM

 PENNSYLVANIA (00Z RUC)...OR NORTHERN WEST VIRGINIA (18Z AND 00Z

 NORTHERN SHIELD OF PRECIPITATION HEADS OUR WAY AFTER 03Z                       
 MONDAY...AND POSSIBLY MAKING IT AS FAR NORTH AS HOUGHTON.  ADDED               
 LIKELY POPS FOR SOUTHERN AREA MONDAY AS THE BULK OF PRECIPITATION              
 HEADS OUR WAY.  PLENTY OF CLOUDS WILL ALSO BEGIN TO INVADE SUNDAY              
 NIGHT...AND REMAIN OVER THE CWA THROUGH MONDAY NIGHT.                          
 ALSO FOR THIS TIME PERIOD...WE WILL BE MONITORING LAKE SUPERIOR AND            
 WINDS...AS A LAKE EFFECT SNOW ADVISORY HAS BEEN POSTED FOR MARQUETTE

 GIVEN THE DEEPER AND MORE WESTWARD SURFACE LOW ACROSS THE MID                  
 ATLANTIC...AND THE LARGE AREA OF HIGH PRESSURE APPROACHING FROM THE            
 WEST.  IN GENERAL...HAVE ANGLED THE FORECAST MORE IN LINE WITH THE             
 MORE MOIST GFS FOR THIS PERIOD.  WILL NEED TO MONITOR THE EXTREME

 THREE LAYERED STORM WHICH CREATED HAVOC ACROSS MISSOURI THROUGH                
 THE WEEKEND IS NOW WELL TO THE EAST. THE LAST HURRAH FROM THIS

 UPPER 20S IN ILLINOIS DOWN TO THE MIDDLE TEENS ACROSS CENTRAL                  
 MISSOURI. MODIFIED ARCTIC AIR WILL SETTLE DOWN ACROSS THE BISTATE

 WIND CHILL VALUES 0 TO 10 BELOW THERE. THE EASTERN COUNTIES WON`T              
 GET AS COLD BECAUSE THE CLOUDS WILL HANG IN LONGER.                            
 WINDS WILL SETTLE TO 10 TO 15 MPH THROUGH THE NIGHT AND THEN                   
 DIE OUT TOMORROW AND TOMORROW NIGHT AS THE HIGH PRESSURE RIDGE

 BUT GETS KICKED EAST INTO THE PLAINS BY ANOTHER SHORT WAVE THAT                
 DROPS INTO ITS PLACE. THE AIR WILL BE TOO DRY AND NOTHING OF                   
 CONSEQUENCE IS ANTICIPATED WITH IT.                                            
 OF INTEREST HOWEVER IS THE WEEKEND OUTLOOK.  SURROUNDING OFFICES               
 DID NOT WANT TO PUT PRECIPITATION IN UNTIL MONDAY. HOWEVER THE                 
 EUROPEAN MODEL HAS BEEN DOING PRETTY WELL OF LATE IN THE MEDIUM                
 RANGE SYNOPTIC PATTERN AND IT HAS A PRETTY DECENT CHUNK OF ENERGY              
 MOVING OUT OF THE ROCKIES INTO THE CENTRAL PLAINS AND PRECIPITATION            
 WILL PROBABLY BREAK OUT FOR SUNDAY INTO MONDAY ACROSS OUR FORECAST             
 AREA. THE EUROPEAN WOULD POINT TO MIXED PRECIPITATION...RAIN SOUTH...          
 MIXED CENTRAL AND SNOW TO MIXED NORTH. WE WILL WAIT TO TAKE A                  
 CLOSER LOOK AT IT TOMORROW AND SEE IF THE MODELS CONTINUE TO                   
 BRING IT ALONG.                                                                
 IN THE LONGER RANGE IT APPEARS ANOTHER COLD FRONT WILL DRIFT                   
 SOUTHEAST REINFORCING THE COOL AIR FOR FRIDAY INTO SATURDAY.

 CLEARLY THE EVENT SHOULD BE ENDING SOON FOR THIS AREA. AS

 SHORT TERM /TODAY/...                                                          
 WE ANTICIPATE AN EARLY ISSUANCE OF THE FORECAST PRODUCTS THIS                  
 MORNING TO GET AS MUCH LEAD TIME AS POSSIBLE FOR FLAG UPGRADES.                
 A POTENTIALLY DANGEROUS SITUATION IS SETTING UP FOR THE EASTERN                
 FORECAST AREA. WHILE THE FOCUS HAS RIGHTLY BEEN ON ICE                         
 ACCUMULATION OVER THE FINGER LAKES, ONONDAGA, MADISON, AND ONEIDA              
 COUNTIES, NEW MESOSCALE MODEL GUIDANCE IS SUGGESTING SIGNIFICANT               
 ICE ACCUMULATION INTO THE CATSKILLS REGION, AND MAYBE EVEN THE POCONOS.        
 A LARGE POOL OF VERY COLD AIR IS IN PLACE OVER EXTREME NORTHERN                
 NEW YORK AND NEW ENGLAND, INTO QUEBEC PROVINCE. RUC40 AND NAM12                
 SFC TEMP FIELDS EACH SHOW THIS COLD AIR BLEEDING SOUTHWARD INTO                
 THE CATSKILLS OVER THE NEXT SEVERAL HOURS, AND REMAINING FIXED FOR             
 A GOOD PORTION OF TODAY. THIS IS CONSISTENT WITH CLIMATOLOGY...WE              
 HAVE SEEN THIS MANY TIMES. IN THE MEANTIME MOISTURE IS STREAMING               
 NORTHWARD AS ANTICIPATED. GIVEN THE STRONG TEMP GRADIENT FORECAST              
 OVER THE EASTERN FA, PLUS THE ADDED TERRAIN LIFT, THINK THIS AREA              
 COULD RECEIVE MORE FREEZING RAIN AND SLEET THAN PREVIOUSLY                     
 EXPECTED THIS MORNING/AFTERNOON. IF ONE IS TO BUY THE SFC GUIDANCE             
 AS ADVERTISED, THE FREEZING LINE DIPS SOUTHWESTWARD INTO                       
 PIKE/WAYNE COUNTIES. THIS REGION WILL BE "ON THE EDGE." SO WHAT WE             
 PROPOSE TO DO IS UPGRADE EASTERN NY COUNTIES TO A WINTER STORM                 
 WARNING, AND ADD AN ADVISORY FOR PIKE/SOUTHERN WAYNE.                          
 DIFFERENT TIMING SCENARIO BUT SIMILAR RESULTS FOR SOUTHERN TIER OF             
 NY AND OTHER PORTIONS OF NORTHEASTERN PA. COLD AIR IS ALREADY IN               
 PLACE OVER TWIN TIERS, WITH STEUBEN CTY IN MID 20S EARLY THIS                  
 MORNING AND UPPER 20S EXTENDING EASTWARD THROUGH BROOME COUNTY.                
 WITH TEMPERATURES THIS FAR BELOW FREEZING, AND EXPECTED TO REMAIN              
 BELOW FREEZING A FEW HOURS LONGER THAN EXPECTED THIS MORNING, WE               
 WILL UPGRADE THIS REGION TO A WARNING TOO FOR FREEZING RAIN AND                
 SLEET.                                                                         
 MESO-OBS SHOW TEMPS OVER SULLIVAN AND WYOMING CTYS IN PA HOVERING              
 AROUND FREEZING MARK TOO. AN ADVISORY IS NEEDED HERE. THE LATER                
 CREWS SHOULD BE ABLE TO DROP THIS ADVISORY BY MID MORNING, BUT FOR             
 NOW IT NEEDS TO BE ADDED TO THE SUITE.                                         
 COLD FRONT PUSHES THROUGH TONIGHT. GIVEN VERY TIGHT TEMP GRADIENT,             
 AND FORECASTED FORCING/OMEGA ALONG THE FRONT, CAN SEE POTENTIAL                
 FOR A SQUALL DROPPING SOUTHEASTWARD WITH FRONT DURING EVENING                  
 HOURS. THIS IS SOMETHING WE NEED TO KEEP AN EYE ON UPSTREAM, AS IT             
 WOULD ENTER THE NORTHWESTERN FORECAST AREA JUST AN HOUR OR TWO                 
 AFTER PEAK DRIVE TIME.                                                         
 MUCH COLDER AIR WILL SPAWN LAKE EFFECT SNOW SHOWERS TUESDAY AND                
 TUESDAY NIGHT. HOWEVER ORGANIZATION LOOKS WEAK AT THIS POINT, AND

 WE ANTICIPATE AN EARLY ISSUANCE OF THE FORECAST PRODUCTS THIS                  
 MORNING TO GET AS MUCH LEAD TIME AS POSSIBLE FOR FLAG UPGRADES.                
 A POTENTIALLY DANGEROUS SITUATION IS SETTING UP FOR THE EASTERN                
 FORECAST AREA. WHILE THE FOCUS HAS RIGHTLY BEEN ON ICE                         
 ACCUMULATION OVER THE FINGER LAKES, ONONDAGA, MADISON, AND ONEIDA              
 COUNTIES, NEW MESOSCALE MODEL GUIDANCE IS SUGGESTING SIGNIFICANT               
 ICE ACCUMULATION INTO THE CATSKILLS REGION, AND MAYBE EVEN THE POCONOS.        
 A LARGE POOL OF VERY COLD AIR IS IN PLACE OVER EXTREME NORTHERN                
 NEW YORK AND NEW ENGLAND, INTO QUEBEC PROVINCE. RUC40 AND NAM12                
 SFC TEMP FIELDS EACH SHOW THIS COLD AIR BLEEDING SOUTHWARD INTO                
 THE CATSKILLS OVER THE NEXT SEVERAL HOURS, AND REMAINING FIXED FOR             
 A GOOD PORTION OF TODAY. THIS IS CONSISTENT WITH CLIMATOLOGY...WE              
 HAVE SEEN THIS MANY TIMES. IN THE MEANTIME MOISTURE IS STREAMING               
 NORTHWARD AS ANTICIPATED. GIVEN THE STRONG TEMP GRADIENT FORECAST              
 OVER THE EASTERN FA, PLUS THE ADDED TERRAIN LIFT, THINK THIS AREA              
 COULD RECEIVE MORE FREEZING RAIN AND SLEET THAN PREVIOUSLY                     
 EXPECTED THIS MORNING/AFTERNOON. IF ONE IS TO BUY THE SFC GUIDANCE             
 AS ADVERTISED, THE FREEZING LINE DIPS SOUTHWESTWARD INTO                       
 PIKE/WAYNE COUNTIES. THIS REGION WILL BE "ON THE EDGE." SO WHAT WE             
 PROPOSE TO DO IS UPGRADE EASTERN NY COUNTIES TO A WINTER STORM                 
 WARNING, AND ADD AN ADVISORY FOR PIKE/SOUTHERN WAYNE.                          
 DIFFERENT TIMING SCENARIO BUT SIMILAR RESULTS FOR SOUTHERN TIER OF             
 NY AND OTHER PORTIONS OF NORTHEASTERN PA. COLD AIR IS ALREADY IN               
 PLACE OVER TWIN TIERS, WITH STEUBEN CTY IN MID 20S EARLY THIS                  
 MORNING AND UPPER 20S EXTENDING EASTWARD THROUGH BROOME COUNTY.                
 WITH TEMPERATURES THIS FAR BELOW FREEZING, AND EXPECTED TO REMAIN              
 BELOW FREEZING A FEW HOURS LONGER THAN EXPECTED THIS MORNING, WE               
 WILL UPGRADE THIS REGION TO A WARNING TOO FOR FREEZING RAIN AND                
 SLEET.                                                                         
 MESO-OBS SHOW TEMPS OVER SULLIVAN AND WYOMING CTYS IN PA HOVERING              
 AROUND FREEZING MARK TOO. AN ADVISORY IS NEEDED HERE. THE LATER                
 CREWS SHOULD BE ABLE TO DROP THIS ADVISORY BY MID MORNING, BUT FOR             
 NOW IT NEEDS TO BE ADDED TO THE SUITE.                                         
 COLD FRONT PUSHES THROUGH TONIGHT. GIVEN VERY TIGHT TEMP GRADIENT,             
 AND FORECASTED FORCING/OMEGA ALONG THE FRONT, CAN SEE POTENTIAL                
 FOR A SQUALL DROPPING SOUTHEASTWARD WITH FRONT DURING EVENING                  
 HOURS. THIS IS SOMETHING WE NEED TO KEEP AN EYE ON UPSTREAM, AS IT             
 WOULD ENTER THE NORTHWESTERN FORECAST AREA JUST AN HOUR OR TWO                 
 AFTER PEAK DRIVE TIME.                                                         
 MUCH COLDER AIR WILL SPAWN LAKE EFFECT SNOW SHOWERS TUESDAY AND                
 TUESDAY NIGHT. HOWEVER ORGANIZATION LOOKS WEAK AT THIS POINT, AND              
 AM NOT YET SOLD ON ANYTHING BUT LIGHT ACCUMULATION.  DJP

 LOOKED VERY GOOD. SOME LES LIKELY TUES NGT INTO WED ON A COLD NW

 SHORT TERM /TODAY/...                                                          
 WE ANTICIPATE AN EARLY ISSUANCE OF THE FORECAST PRODUCTS THIS                  
 MORNING TO GET AS MUCH LEAD TIME AS POSSIBLE FOR FLAG UPGRADES.                
 A POTENTIALLY DANGEROUS SITUATION IS SETTING UP FOR THE EASTERN                
 FORECAST AREA. WHILE THE FOCUS HAS RIGHTLY BEEN ON ICE                         
 ACCUMULATION OVER THE FINGER LAKES, ONONDAGA, MADISON, AND ONEIDA              
 COUNTIES, NEW MESOSCALE MODEL GUIDANCE IS SUGGESTING SIGNIFICANT               
 ICE ACCUMULATION INTO THE CATSKILLS REGION, AND MAYBE EVEN THE POCONOS.        
 A LARGE POOL OF VERY COLD AIR IS IN PLACE OVER EXTREME NORTHERN                
 NEW YORK AND NEW ENGLAND, INTO QUEBEC PROVINCE. RUC40 AND NAM12                
 SFC TEMP FIELDS EACH SHOW THIS COLD AIR BLEEDING SOUTHWARD INTO                
 THE CATSKILLS OVER THE NEXT SEVERAL HOURS, AND REMAINING FIXED FOR             
 A GOOD PORTION OF TODAY. THIS IS CONSISTENT WITH CLIMATOLOGY...WE              
 HAVE SEEN THIS MANY TIMES. IN THE MEANTIME MOISTURE IS STREAMING               
 NORTHWARD AS ANTICIPATED. GIVEN THE STRONG TEMP GRADIENT FORECAST              
 OVER THE EASTERN FA, PLUS THE ADDED TERRAIN LIFT, THINK THIS AREA              
 COULD RECEIVE MORE FREEZING RAIN AND SLEET THAN PREVIOUSLY                     
 EXPECTED THIS MORNING/AFTERNOON. IF ONE IS TO BUY THE SFC GUIDANCE             
 AS ADVERTISED, THE FREEZING LINE DIPS SOUTHWESTWARD INTO                       
 PIKE/WAYNE COUNTIES. THIS REGION WILL BE "ON THE EDGE." SO WHAT WE             
 PROPOSE TO DO IS UPGRADE EASTERN NY COUNTIES TO A WINTER STORM                 
 WARNING, AND ADD AN ADVISORY FOR PIKE/SOUTHERN WAYNE.                          
 DIFFERENT TIMING SCENARIO BUT SIMILAR RESULTS FOR SOUTHERN TIER OF             
 NY AND OTHER PORTIONS OF NORTHEASTERN PA. COLD AIR IS ALREADY IN               
 PLACE OVER TWIN TIERS, WITH STEUBEN CTY IN MID 20S EARLY THIS                  
 MORNING AND UPPER 20S EXTENDING EASTWARD THROUGH BROOME COUNTY.                
 WITH TEMPERATURES THIS FAR BELOW FREEZING, AND EXPECTED TO REMAIN              
 BELOW FREEZING A FEW HOURS LONGER THAN EXPECTED THIS MORNING, WE               
 WILL UPGRADE THIS REGION TO A WARNING TOO FOR FREEZING RAIN AND                
 SLEET.                                                                         
 MESO-OBS SHOW TEMPS OVER SULLIVAN AND WYOMING CTYS IN PA HOVERING              
 AROUND FREEZING MARK TOO. AN ADVISORY IS NEEDED HERE. THE LATER                
 CREWS SHOULD BE ABLE TO DROP THIS ADVISORY BY MID MORNING, BUT FOR             
 NOW IT NEEDS TO BE ADDED TO THE SUITE.                                         
 COLD FRONT PUSHES THROUGH TONIGHT. GIVEN VERY TIGHT TEMP GRADIENT,             
 AND FORECASTED FORCING/OMEGA ALONG THE FRONT, CAN SEE POTENTIAL                
 FOR A SQUALL DROPPING SOUTHEASTWARD WITH FRONT DURING EVENING                  
 HOURS. THIS IS SOMETHING WE NEED TO KEEP AN EYE ON UPSTREAM, AS IT             
 WOULD ENTER THE NORTHWESTERN FORECAST AREA JUST AN HOUR OR TWO                 
 AFTER PEAK DRIVE TIME.                                                         
 MUCH COLDER AIR WILL SPAWN LAKE EFFECT SNOW SHOWERS TUESDAY AND                
 TUESDAY NIGHT. HOWEVER ORGANIZATION LOOKS WEAK AT THIS POINT, AND              
 AM NOT YET SOLD ON ANYTHING BUT LIGHT ACCUMULATION.  DJP

 A POTENTIALLY DANGEROUS SITUATION IS SETTING UP FOR THE EASTERN

 A LARGE POOL OF VERY COLD AIR IS IN PLACE OVER EXTREME NORTHERN

 A GOOD PORTION OF TODAY. THIS IS CONSISTENT WITH CLIMATOLOGY...WE              
 HAVE SEEN THIS MANY TIMES. IN THE MEANTIME MOISTURE IS STREAMING               
 NORTHWARD AS ANTICIPATED. GIVEN THE STRONG TEMP GRADIENT FORECAST              
 OVER THE EASTERN FA, PLUS THE ADDED TERRAIN LIFT, THINK THIS AREA              
 COULD RECEIVE MORE FREEZING RAIN AND SLEET THAN PREVIOUSLY                     
 EXPECTED THIS MORNING/AFTERNOON. IF ONE IS TO BUY THE SFC GUIDANCE

 FOR A SQUALL DROPPING SOUTHEASTWARD WITH FRONT DURING EVENING

 .SHORT TERM /TODAY/...                                                         
 WE ANTICIPATE AN EARLY ISSUANCE OF THE FORECAST PRODUCTS THIS                  
 MORNING TO GET AS MUCH LEAD TIME AS POSSIBLE FOR FLAG UPGRADES.                
 A POTENTIALLY DANGEROUS SITUATION IS SETTING UP FOR THE EASTERN                
 FORECAST AREA. WHILE THE FOCUS HAS RIGHTLY BEEN ON ICE                         
 ACCUMULATION OVER THE FINGER LAKES, ONONDAGA, MADISON, AND ONEIDA              
 COUNTIES, NEW MESOSCALE MODEL GUIDANCE IS SUGGESTING SIGNIFICANT               
 ICE ACCUMULATION INTO THE CATSKILLS REGION, AND MAYBE EVEN THE POCONOS.        
 A LARGE POOL OF VERY COLD AIR IS IN PLACE OVER EXTREME NORTHERN                
 NEW YORK AND NEW ENGLAND, INTO QUEBEC PROVINCE. RUC40 AND NAM12                
 SFC TEMP FIELDS EACH SHOW THIS COLD AIR BLEEDING SOUTHWARD INTO                
 THE CATSKILLS OVER THE NEXT SEVERAL HOURS, AND REMAINING FIXED FOR             
 A GOOD PORTION OF TODAY. THIS IS CONSISTENT WITH CLIMATOLOGY...WE              
 HAVE SEEN THIS MANY TIMES. IN THE MEANTIME MOISTURE IS STREAMING               
 NORTHWARD AS ANTICIPATED. GIVEN THE STRONG TEMP GRADIENT FORECAST              
 OVER THE EASTERN FA, PLUS THE ADDED TERRAIN LIFT, THINK THIS AREA              
 COULD RECEIVE MORE FREEZING RAIN AND SLEET THAN PREVIOUSLY                     
 EXPECTED THIS MORNING/AFTERNOON. IF ONE IS TO BUY THE SFC GUIDANCE             
 AS ADVERTISED, THE FREEZING LINE DIPS SOUTHWESTWARD INTO                       
 PIKE/WAYNE COUNTIES. THIS REGION WILL BE "ON THE EDGE." SO WHAT WE             
 PROPOSE TO DO IS UPGRADE EASTERN NY COUNTIES TO A WINTER STORM                 
 WARNING, AND ADD AN ADVISORY FOR PIKE/SOUTHERN WAYNE.                          
 DIFFERENT TIMING SCENARIO BUT SIMILAR RESULTS FOR SOUTHERN TIER OF             
 NY AND OTHER PORTIONS OF NORTHEASTERN PA. COLD AIR IS ALREADY IN               
 PLACE OVER TWIN TIERS, WITH STEUBEN CTY IN MID 20S EARLY THIS                  
 MORNING AND UPPER 20S EXTENDING EASTWARD THROUGH BROOME COUNTY.                
 WITH TEMPERATURES THIS FAR BELOW FREEZING, AND EXPECTED TO REMAIN              
 BELOW FREEZING A FEW HOURS LONGER THAN EXPECTED THIS MORNING, WE               
 WILL UPGRADE THIS REGION TO A WARNING TOO FOR FREEZING RAIN AND                
 SLEET.                                                                         
 MESO-OBS SHOW TEMPS OVER SULLIVAN AND WYOMING CTYS IN PA HOVERING              
 AROUND FREEZING MARK TOO. AN ADVISORY IS NEEDED HERE. THE LATER                
 CREWS SHOULD BE ABLE TO DROP THIS ADVISORY BY MID MORNING, BUT FOR             
 NOW IT NEEDS TO BE ADDED TO THE SUITE.                                         
 COLD FRONT PUSHES THROUGH TONIGHT. GIVEN VERY TIGHT TEMP GRADIENT,             
 AND FORECASTED FORCING/OMEGA ALONG THE FRONT, CAN SEE POTENTIAL                
 FOR A SQUALL DROPPING SOUTHEASTWARD WITH FRONT DURING EVENING                  
 HOURS. THIS IS SOMETHING WE NEED TO KEEP AN EYE ON UPSTREAM, AS IT             
 WOULD ENTER THE NORTHWESTERN FORECAST AREA JUST AN HOUR OR TWO                 
 AFTER PEAK DRIVE TIME.                                                         
 MUCH COLDER AIR WILL SPAWN LAKE EFFECT SNOW SHOWERS TUESDAY AND                
 TUESDAY NIGHT. HOWEVER ORGANIZATION LOOKS WEAK AT THIS POINT, AND              
 AM NOT YET SOLD ON ANYTHING BUT LIGHT ACCUMULATION.  DJP

 LOOKED VERY GOOD. SOME LES LIKELY TUES NGT INTO WED ON A COLD NW

 OF MDT PRECIP MOVING INTO WRN NY MAY CHANGE THERMAL PROFILE TO                 
 CREATE MORE OF A MIX. STILL THINK LIGHT ICING WILL OCCUR ACROSS                
 THE FINGER LAKES AND WRN MHWK VALLEY. ELSEWHERE...JUST MINOR TWEEKS            
 TO THE POSITION OF WHERE IT IS MAINLY RAIN...VERSUS THE MIX AND TO             
 LOWER TEMPS UP NORTH A TAD. RADAR TRENDS AND LATEST GUIDANCE

 WORRIED ABOUT A MAJOR ICE STORM IN THE FINGER LAKES AND UPPER                  
 SUSQUEHANNA REGION...AS WELL AS THE MOUNTAIN TOPS OF THE WRN

 CATEGORICAL POPS AS WAVE PRODUCING MIXED PRECIP OVER MI MOVES EAST             
 THIS AFTERNOON WITH ANOTHER SLUG OF MOISTURE. CHANGED SOME PTYPES              
 THIS AFTERNOON UP NORTH TO INCLUDE BURSTS OF SLEET/SNOW AND EVEN RAIN...BUT    
 DID NOT EXTEND ADVISORIES ACROSS THE NORTH COUNTRY JUST YET SO WE              
 CAN WATCH SFC TEMP TRENDS UNTIL 11 AM OR SO TO SEE IF THEY RECOVER.            
 OUR HUNCH IS THOUGH THAT AN EXTENSION OF ADVISORIES THROUGH THE                
 AFTERNOON IS LIKELY ACROSS THE NORTH. TONIGHT STILL LOOKS VERY                 
 INTERESTING...WITH POTENTIAL FOR DANGEROUS ICE STORM STILL LOOMING             
 OVER OUR NORTHERN AREAS ESPECIALLY. MORE LATER.

 LATEST MODEL RUNS DID NOT SHOW AS MUCH CHANGE AS DID PRIOR RUNS,               
 THOUGH BOTH NAM AND COOLER GFS CONTINUE TO PUSH WARM AIR FURTHER               
 NORTHWARD. WHAT IS OBVIOUS IS NORTHERN PORTION OF FA WILL                      
 EXPERIENCE A SIGNIFICANT MIXED PRECIPITATION EVENT, WITH AN                    
 ELONGATED PERIOD OF FREEZING RAIN EXPECTED. EXACTLY WHERE TO DRAW              
 THE LINE IS THE DIFFICULT PART.                                                
 BASED ON CURRENT OBS SHOWING COLD AIR PUSHING SOUTHEAST UNDER DOME             
 OF HIGH PRESSURE, WE WENT A TAD COOLER THAN THE CURRENT NAM                    
 SOLUTION AT THE LOWEST LEVELS. THE AREA FROM SYR OVER TO RME/UCA               
 LOOKS MOST DANGEROUS, WITH FORECAST SOUNDINGS SUGGESTING                       
 PREDOMINANT FREEZING RAIN THIS EVENING INTO MONDAY EVENING. SLEET              
 AND SNOW WILL MIX IN TOO, BUT WE THINK SNOW ACCUMS WILL BE IN 1-4              
 INCH RANGE WITH THE HIGHEST AMTS ON THE HIGH TERRAIN OF                        
 ONEIDA/MADISON COUNTIES, AND POSSIBLY DOWN TOWARD CICERO IN                    
 ONONDAGA. JUST CANNOT GET EXCITED ABOUT SNOW IN THIS REGION GIVEN              
 HEIGHT OF DENDRITE LAYER. THE MAIN STORY WILL BE THE FREEZING                  
 RAIN.                                                                          
 SOUTH TO THE TWIN TIERS, THE SOUNDINGS ARE NOT AS CLEAR CUT. ITH               
 NAM SOUNDING, AGAIN WITH SOME SFC MODIFICATION, SUGGESTS FREEZING              
 RAIN MUCH OF SUNDAY NIGHT AND EARLY MONDAY MORNING. THEN ENOUGH                
 WARM AIR PUSHES NORTH TO CHANGE PRECIP TO ALL RAIN. ELM AND BGM

 2-4 HOUR PERIOD OF SNOW SHOWERS, PROBABLY WITH SOME ACCUMULATION               
 AS DENDRITE LAYER LOWERS FAST. HOWEVER DRIER AIR WORKS IN QUICKLY              
 AND SHOULD CUT OFF BULK OF PRECIP.                                             
 WITH THAT IN MIND WE ARE ISSUING A WINTER STORM WARNING FOR OUR

 CAN WATCH SFC TEMP TRENDS UNTIL 11 AM OR SO TO SEE IF THEY RECOVER.            
 OUR HUNCH IS THOUGH THAT AN EXTENSION OF ADVISORIES THROUGH THE                
 AFTERNOON IS LIKELY ACROSS THE NORTH. TONIGHT STILL LOOKS VERY

 SHORT TERM /TODAY THROUGH MONDAY NIGHT/...                                     
 LATEST MODEL RUNS DID NOT SHOW AS MUCH CHANGE AS DID PRIOR RUNS,               
 THOUGH BOTH NAM AND COOLER GFS CONTINUE TO PUSH WARM AIR FURTHER               
 NORTHWARD. WHAT IS OBVIOUS IS NORTHERN PORTION OF FA WILL                      
 EXPERIENCE A SIGNIFICANT MIXED PRECIPITATION EVENT, WITH AN                    
 ELONGATED PERIOD OF FREEZING RAIN EXPECTED. EXACTLY WHERE TO DRAW              
 THE LINE IS THE DIFFICULT PART.                                                
 BASED ON CURRENT OBS SHOWING COLD AIR PUSHING SOUTHEAST UNDER DOME             
 OF HIGH PRESSURE, WE WENT A TAD COOLER THAN THE CURRENT NAM                    
 SOLUTION AT THE LOWEST LEVELS. THE AREA FROM SYR OVER TO RME/UCA               
 LOOKS MOST DANGEROUS, WITH FORECAST SOUNDINGS SUGGESTING                       
 PREDOMINANT FREEZING RAIN THIS EVENING INTO MONDAY EVENING. SLEET              
 AND SNOW WILL MIX IN TOO, BUT WE THINK SNOW ACCUMS WILL BE IN 1-4              
 INCH RANGE WITH THE HIGHEST AMTS ON THE HIGH TERRAIN OF                        
 ONEIDA/MADISON COUNTIES, AND POSSIBLY DOWN TOWARD CICERO IN                    
 ONONDAGA. JUST CANNOT GET EXCITED ABOUT SNOW IN THIS REGION GIVEN              
 HEIGHT OF DENDRITE LAYER. THE MAIN STORY WILL BE THE FREEZING                  
 RAIN.                                                                          
 SOUTH TO THE TWIN TIERS, THE SOUNDINGS ARE NOT AS CLEAR CUT. ITH               
 NAM SOUNDING, AGAIN WITH SOME SFC MODIFICATION, SUGGESTS FREEZING              
 RAIN MUCH OF SUNDAY NIGHT AND EARLY MONDAY MORNING. THEN ENOUGH                
 WARM AIR PUSHES NORTH TO CHANGE PRECIP TO ALL RAIN. ELM AND BGM                
 PAINT SIMILAR PICTURES.                                                        
 THE COLD FRONT RIPS THROUGH AROUND 0Z TUESDAY. THERE COULD BE A                
 2-4 HOUR PERIOD OF SNOW SHOWERS, PROBABLY WITH SOME ACCUMULATION               
 AS DENDRITE LAYER LOWERS FAST. HOWEVER DRIER AIR WORKS IN QUICKLY              
 AND SHOULD CUT OFF BULK OF PRECIP.                                             
 WITH THAT IN MIND WE ARE ISSUING A WINTER STORM WARNING FOR OUR                
 NORTHERN FA, DOWN THROUGH CORTLAND-CHENANGO COUNTIES. THE TWIN

 THE NORTH OF THE FRONT. A STRONG WAVE OF LOW PRESSURE MOVING UP THE

 850 MB WINDS OF ABOUT 20 KTS AND THE SHALLOW DEPTH OF THE UNSTABLE

 SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...                                  
 FRONT REMAINS DRAPED ACROSS THE AREA. SHOWERS CONTINUE...MAINLY TO             
 THE NORTH OF THE FRONT. A STRONG WAVE OF LOW PRESSURE MOVING UP THE            
 FRONT WILL ENHANCE THE PRECIPITATION AND RESULT IN WIDESPREAD                  
 RAINFALL TONIGHT. FLOOD WATCH IS IN EFFECT ALL ZONES.                          
 AS THE LOW CONTINUES ON A NORTHEASTERLY TRACK ON MONDAY...IT WILL              
 DRAG THE FRONT EAST OF THE AREA AND ALLOW COLDER AND DRIER AIR TO              
 FILTER IN. TEMPERATURES WILL BE COLD ENOUGH FOR SNOW BY MONDAY                 
 NIGHT...AND THOUGH MOISTURE WITH THE LOW WILL BE GONE...THE FLOW               
 BEHIND THE LOW WILL BE CONDUCIVE FOR LAKE ENHANCED SNOW SHOWERS. 850           
 MB TO LAKE SURFACE TEMPERATURE DIFFERENTIALS WILL BE IMPRESSIVE AT             
 GREATER THAN 15 DEGREES CELSIUS. IN ADDITION...THE RELATIVELY STRONG           
 850 MB WINDS OF ABOUT 20 KTS AND THE SHALLOW DEPTH OF THE UNSTABLE             
 LAYER WILL ALLOW THE LAKE MOISTURE TO REACH THIS FAR INLAND. WENT              
 WITH A CHANCE OF SNOW SHOWERS MONDAY NIGHT THROUGH TUESDAY                     
 AFTERNOON. AS USUAL WITH LAKE EFFECT SITUATIONS IN THE ILN AREA...WE           
 ARE EXPECTING LIGHT SNOW ACCUMULATIONS. SNOW SHOWERS WILL END                  
 TUESDAY AFTERNOON WHEN THE AIRMASS BECOMES TO DRY FOR SNOW TO FORM.            
 SKIES WILL BECOME MOSTLY CLEAR TUESDAY NIGHT AS HIGH PRESSURE BUILDS

 HEBBRONVILLE AND FALFURRIAS TO 45 DEGREES AT WESLACO AND BAYVIEW.              
 GFS AND ETA FORECAST SOUNDINGS BOTH SHOW TEMPS DROPPING BELOW                  
 FREEZING FROM AROUND 850 TO 975 MB BY 18Z TUESDAY WHICH WILL                   
 PROVIDE A PRETTY SUBSTANTIAL FREEZING LAYER. ANY SIGNIFICANT RAIN              
 THAT FALLS THROUGH THIS LAYER HAS THE POTENTIAL FOR SLEET FORMATION            
 LATER TONIGHT INTO TUESDAY. HOWEVER...SOME MAJOR DIFFENCES SHOW UP             
 CONCERNING PROGGED MOISTURE LEVELS NEAR THIS COLD LAYER. THE ETA               
 SHOWS PRETTY SIGNIFICANT DRYING OCCURRING THROUGH 18Z TUES IN                  
 COMPARISON TO THE GFS WHICH HAS A MORE SATURATED FREEZING LAYER                
 ALOFT. THIS IS THE BIG FLY IN THE OINTMENT. IF THIS ELEVATED COLD              
 LAYER DOES DRY OUT SOMEWHAT...THIS WILL IN TURN DIMINISH POPS AND              
 ACCORDINGLY...WILL DIMINISH THE SLEET CHCS. HOWEVER...AM HESITANT TO           
 REDUCE POPS VERY MUCH DURING THE OVERNIGHT PERIOD DUE TO A COUPLE OF           
 REASONS. FIRST...THE GFS CONTINUES TO ADVERTISE SOME POTENTIAL FOR             
 SOME WEAK COASTAL SURFACE TROFFING INTO TOMORROW WHICH WOULD HELP              
 WITH LOW LEVEL CONVERGENCE ACROSS THE EASTERN SECTIONS. SECOND...              
 THE GFS AND RUC GUIDANCE SHOW SOME BETTER 500 MB PVA SKIRTING THE              
 BRO CWA JUST TO THE NORTH AND WEST WHICH MAY ALSO ENHANCE THE LIFT             
 SOMEWHAT ALLOWING A RAIN/SLEET MIXTURE TO BEGIN LATER TONIGHT. THE             
 NAM AND GFS SHOW SOME BETTER AGREEMENT CONCERNING POPS AFTER TONIGHT           
 AS THE NAM PICKS UP ON SOME INVERTED COASTAL SURFACE TROFFING                  
 TUESDAY INTO WEDNESDAY WHICH ALSO HELPS MAINTAIN SOME CHC POPS OUT             
 INTO PERIODS 3 AND 4. THE AIRMASS BEGINS TO MODERATE ON WED AS THE             
 CAA WEAKENS AND WARMER SOUTHWESTERLY FLOW ALOFT TRIES TO BUILD DOWN            
 TO THE SURFACE FINALLY ERODING AWAY THE SUB-FREEZING LAYER AROUND              
 18Z WED. HOWEVER...ENOUGH MOISTURE LINGERS AROUND THE AREA AND THE             
 LOW LEVEL INVERSION HOLDS ON THROUGH THE END OF THE WEEK TO MAINTAIN           
 THE CLOUD COVER...FAIRLY COOL TEMPS AND SLGT CHC/CHC POPS INTO NEXT            
 WEEKEND.  FOR TEMPS WILL GO CLOSER TO THE COOLER MET GUIDANCE FOR              
 BOTH HRL AND BRO.  FURTHER WEST...THE MAV GUIDANCE IS COOLER THAN              
 THE MET AND WILL GO CLOSER TO THESE FOR MFE TEMPS. ALSO...WILL                 
 UPGRADE THE CURRENT FREEZE WATCH TO A WARNING FOR THE NORTHERN FOUR            
 COUNTIES AND WILL ISSUE A WINTER WX ADVISORY FOR MOST OF THE BRO CWA

 .UPDATE...                                                                     
 PROGRESSION OF WINTRY MIX OF PRECIPITATION...AND SUBSEQUENT DRYING/            
 SUBSIDENCE BEHIND THE BAND HAS BEEN MORE PROGRESSIVE THAN EARLIER              
 EXPECTED AND MORE IN LINE WITH THE NAM/RUC MODELS...ESPECIALLY                 
 THEIR NEW 12Z RUNS...AS BEST MID LVL FRONTOGENESIS HAS SHIFTED                 
 OVER SE CWA. EXPECT DISTURBANCES IN SUBTROPICAL JET BRANCH TO                  
 CONTINUE TO GRAZE FAR SE COUNTIES THROUGH AT LEAST 00Z TUES.                   
 ALSO...DEEPER ARCTIC AIRMASS IS NOW ARRIVING PER LATEST VWP AND                
 AREA SOUNDINGS (THOUGH 12Z FWD WAS A NO GO). DESPITE SUNSHINE OVER             
 NW 1/2 OF N TX...DEEP/DENSE AIRMASS THROUGH 5 KFT WON`T ALLOW MUCH             
 IN THE WAY OF WARMING...THOUGH INSOLATION AND TRAFFIC SHOULD HELP              
 IN THE SUBLIMATION AFFECTS OF EARLIER ICE ACCUMULATIONS.                       
 AS A RESULT...ICE STORM WARNING HAS BEEN CANCELED OVER THE NW 1/2...           
 WITH THE FREEZING RAIN ADVISORY CANCELED OVER NE COUNTIES. FREEZING            
 RAIN ADVISORY CONTS OVER SE COUNTIES (SE OF A LAMPASAS...WACO...               
 CORSICANA...CANTON LINE). SEE ADVISORY LINE BELOW. ADVISORY/WARNING

 12Z AVIATION UPDATE...BACK EDGE OF THE PRECIPITATION IS MOVING                 
 THROUGH THE METROPLEX NOW...BUT SEVERAL OB SITES STILL REPORTING               
 SOME LIGHT FREEZING RAIN AND SLEET. SATELLITE IMAGERY SHOWS SOME               
 CLEARING TO THE WEST...BUT STRONG SW FLOW ALOFT MAY KEEP SOME HIGH             
 CLOUDINESS AROUND FOR A WHILE. WILL START OUT WITH IMPROVING CONDS             
 AND ONLY KEEP A TEMPO GROUP IN UNTIL 14Z TO COVER LINGERING SLEET              
 SHOWERS. CIGS IMPROVE TO VFR BY MID MORNING BUT GUSTY NORTHERLY                
 WINDS WILL PERSIST THROUGH THE EARLY AFTERNOON. EXPECT VFR                     
 CIGS/VIS THROUGH THE END OF THE PERIOD.

 PREV DISCUSSION... /ISSUED 409 AM CST MON JAN 15 2007/                         
 MOST OF THE WINTER PRECIPITATION WILL SLOWLY COME TO AN END                    
 TODAY...AT LEAST IN THE ICE STORM WARNING AREA. HOWEVER...LIGHT                
 PRECIP WILL CONTINUE INTO THE EVENING IN THE FAR SOUTH. WITH THE               
 PRECIP SLOW TO END...WE WILL EXTEND THE ICE STORM WARNING UNTIL                
 NOON TODAY AND CONTINUE THE FREEZING RAIN ADVISORY IN THE EAST.                
 THE ADVISORY MAY HAVE TO BE ADJUSTED FOR TONIGHT BUT CONSIDERING               
 THE SLOW MOVEMENT AND OTHER FACTORS...THIS WILL BE BETTER HANDLED              
 BY THE DAY CREW.                                                               
 ADDITIONAL ICE ACCUMULATIONS WILL BE LESS THAN ONE QUARTER OF AN               
 INCH IN THE WARNING AREA. MOST OF THE AREA IS WELL BELOW FREEZING              
 THIS MORNING AND WITH OVERNIGHT RAIN...ICE HAS BECOME MORE OF A                
 PROBLEM...ESPECIALLY ON ELEVATED SURFACES. THE MORNING COMMUTE                 
 WILL BE EXTREMELY DIFFICULT FOR MANY. WITH CONDITIONS IMPROVING                
 LATER THIS MORNING AS THE PRECIP MOVES OUT...HOPEFULLY MANY WILL               
 BE ABLE TO DELAY THEIR TRAVELS A FEW HOURS. STILL...WHERE THE                  
 TEMPERATURE HAS BEEN BELOW FREEZING FOR THE LAST DAY OR SO...ICE               
 HAS BEGUN TO ACCUMULATE ON SURFACES SUCH AS SIDEWALKS...MAKING                 
 EVEN WALKING DIFFICULT AT TIMES. THIS SHOULD ALSO IMPROVE AFTER                
 THE PRECIP ENDS WITH GUSTY NORTH WINDS DRYING SURFACES.                        
 TEMPERATURES WILL REMAIN WELL BELOW NORMAL THIS WEEK...IN FACT                 
 RATHER COLD THE NEXT FEW DAYS AS NORTH WINDS AND CLOUDINESS                    
 PERSIST. LIGHT PRECIP WILL PERSIST TONIGHT IN THE SOUTH BUT DO                 
 NOT ANTICIPATE SIGNIFICANT ACCUMULATIONS...AND TUESDAY WILL BE                 
 DRY. HOWEVER...ON WEDNESDAY WE WILL SEE ANOTHER UPPER LEVEL                    
 DISTURBANCE MOVE ACROSS THE AREA. WITH MORNING SURFACE LOWS WELL               
 BELOW FREEZING...ALONG WITH THE COLUMN OF AIR ABOVE...WE COULD SEE             
 SOME LIGHT SNOW IN THE MORNING...CHANGING MORE TO RAIN BY                      
 AFTERNOON.                                                                     
 TEMPERATURES SHOULD SLOWLY WARM TO MORE NORMAL READINGS AFTER

 CURRENT FORECAST PACKAGE INCLUDING WATCHES/WARNINGS/ADVISORIES LOOK            
 OK FOR NOW.  THE FREEZING LINE HAS NOT MOVED MUCH IN THE LAST 8                
 HOURS.  LARGEST ACCUMULATIONS OF FREEZING RAIN WILL BE NORTH OF AN             
 EASTLAND...MINERAL WELLS...TO GAINESVILLE LINE WHERE PERIODS OF                
 MODERATE TO HEAVY FREEZING RAIN WILL CONTINUE TO CAUSE TRAVEL                  
 PROBLEMS.  ELEVATED...EXPOSED SURFACES FURTHER SOUTH AND EAST IN THE           
 ICE STORM WARNING WILL REMAIN FROZEN BUT AS OF NOW MANY ROADS ARE              
 STILL WET.  TRAVEL IS STILL DISCOURAGED IN THE ICE STORM WARNING DUE           
 TO THE LIKELIHOOD OF ICE ON BRIDGES...OVERPASSES...AND FLY OVERS.              
 STILL APPEARS THAT THE FREEZING LINE WILL SLIDE THROUGH NEARLY ALL             
 OF NORTH TEXAS TONIGHT. WE WILL MOST LIKELY CHANGE THE WINTER STORM            
 WATCH IN THE SOUTHEAST TO A FREEZING RAIN ADVISORY TONIGHT AND                 
 MONDAY AS ICE ACCUMULATIONS SHOULD BE LESS THAN 1/4 INCH AND MOST              
 ROADS SHOULD NOT ICE OVER.

 APPARENT.  CIGS ARE LOWERING...LIKELY IN RESPONSE TO THE                       
 APPROACHING SHORTWAVE...WITH PRESSURE FALLS NOTED ACROSS THE STATE.            
 VSBYS WILL ALSO FALL TO MVFR/IFR DURING THE MORNING HOURS WITH FZDZ            
 ACCOMPANYING THE BR AT TIMES. INCREASING 850 MB FLOW SHOULD ENHANCE            
 ISENTROPIC LIFT DURING THE NEXT FEW HOURS WITH AN INCREASE IN SHRA.            
 RUC/NAM FORECASTS ARE DEPICTING A TRAJECTORY OFF THE MEXICAN                   
 MOUNTAINS WHICH BRINGS DRY AIR INTO THE AREA AND ALTERS QPF                    
 PLACEMENT. PREFER THE GFS/UKMET/ECMWF LOW LEVEL WIND FORECAST WHICH            
 ALIGNS WITH THE CURRENT TRENDS...AND SUGGESTS BEST CHANCE OF FZRA              
 OVER THE METROPLEX AFTER 9 AM AND LASTING THROUGH LATE AFTERNOON.              
 SUSPECT THAT BATCH OF SHOWERS NEAR AUSTIN IS THE BEGINNINGS OF THE             
 ACTIVITY THAT WILL AFFECT THE METROPLEX.  FOR ACT SAME TRENDS WITH             
 CIGS/VSBYS HAVE BEEN FORECAST...BUT HAVE KEPT PRECIP LIQUID THROUGH            
 THIS EVENING...BUT CHANGED IT TO FZRA THEREAFTER.  WITH COLD                   
 ADVECTION INCREASING AFTER 0Z...HAVE RAISED CIGS/VSBYS AS COLD LAYER           
 DEEPENS OVER METROPLEX.  SOME SLEET MAY BE POSSIBLE AS WELL.  TR.92

 NORTH TEXAS WEATHER REMAINS VERY INTERESTING TODAY AS WE WILL                  
 CONTINUE TO SEE FREEZING RAIN IN THE WEST...AND A CHANCE OF                    
 FLOODING IN THE EAST. THE FREEZE LINE WILL ALSO NOT MOVE                       
 SIGNIFICANTLY TODAY BUT A SURGE OF MUCH COLDER AIR TONIGHT WILL                
 PUSH IT INTO SOUTHERN ZONES BY MORNING. IN TURN...PRECIP SHOULD                
 END IN NORTHERN PORTIONS TONIGHT...WITH LIGHT WINTER PRECIP                    
 DEVELOPING IN THE SOUTH.  CURRENT ONGOING CONVECTION IN THE                    
 SOUTHEAST WILL BE A PROBLEM AGAIN TODAY. AS FOR HEAVY                          
 RAINS...WHILE WE DO NOT ANTICIPATE THE HEAVY RAINFALL AMOUNTS AS               
 YESTERDAY...IT WILL NOT TAKE MUCH TO CAUSE FLOODING PROBLEMS.                  
 HENCE...WE WILL NOT CHANGE THE CURRENT WATCHES...WARNING OR

 NEXT WAVE OF ENERGY IS EJECTING NORTHEAST INTO THE REGION THIS                 
 MORNING WITH RAIN AREA INCREASING AND MOVING INTO THE WESTERN CWA.             
 THIS WILL BE A SIGNIFICANT PROBLEM AS TEMPERATURES WILL NOT WARM               
 MUCH TODAY...KEEPING WESTERN PORTIONS AT OR BELOW FREEZING AS ICE              
 CONTINUES TO ACCUMULATE. ON RADAR THE RETURNS MAY NOT LOOK                     
 SIGNIFICANT BUT WITH THE TEMPERATURE AT OR BELOW FREEZING FOR SUCH             
 A LONG TIME...EVEN SMALL AMOUNTS CAN CAUSE SIGNIFICANT PROBLEMS ON             
 BRIDGES...OVERPASSES...TREES AND POWER LINES. TOTAL ICE AMOUNTS                
 THROUGH TONIGHT IN THE ICE STORM WARNING AREA WILL RANGE BETWEEN               
 ONE QUARTER AND THREE QUARTERS OF AN INCH. SOME MINOR AMOUNTS OF               
 SLEET WILL BE POSSIBLE LATER TODAY AND TONIGHT.                                
 WINTER PRECIP WILL MOVE INTO THE SOUTHERN PORTIONS LATER TONIGHT AS            
 TEMPERATURES FINALLY BEGIN TO FALL. AT THE SAME TIME...THE SYSTEM              
 WILL BEGIN TO WEAKEN...LESSENING THE CHANCE FOR SIGNIFICANT WINTER             
 PRECIP. HOWEVER...AS EVENTS DEVELOP TODAY AND ADDITIONAL MODEL                 
 DATA IS REVIEWED...THE WATCH WILL BE MODIFIED AS NEEDED.                       
 IN THE EXTENDED PORTION OF THE FORECAST TEMPERATURES REMAIN BELOW              
 NORMAL...BUT SHOULD REMAIN ABOVE FREEZING...WITH PERIODS OF RAIN

 CURRENT FORECAST PACKAGE INCLUDING WATCHES/WARNINGS/ADVISORIES LOOK            
 OK FOR NOW.  THE FREEZING LINE HAS NOT MOVED MUCH IN THE LAST 8                
 HOURS.  LARGEST ACCUMULATIONS OF FREEZING RAIN WILL BE NORTH OF AN             
 EASTLAND...MINERAL WELLS...TO GAINESVILLE LINE WHERE PERIODS OF                
 MODERATE TO HEAVY FREEZING RAIN WILL CONTINUE TO CAUSE TRAVEL                  
 PROBLEMS.  ELEVATED...EXPOSED SURFACES FURTHER SOUTH AND EAST IN THE           
 ICE STORM WARNING WILL REMAIN FROZEN BUT AS OF NOW MANY ROADS ARE              
 STILL WET.  TRAVEL IS STILL DISCOURAGED IN THE ICE STORM WARNING DUE           
 TO THE LIKELIHOOD OF ICE ON BRIDGES...OVERPASSES...AND FLY OVERS.              
 STILL APPEARS THAT THE FREEZING LINE WILL SLIDE THROUGH NEARLY ALL             
 OF NORTH TEXAS TONIGHT. WE WILL MOST LIKELY CHANGE THE WINTER STORM            
 WATCH IN THE SOUTHEAST TO A FREEZING RAIN ADVISORY TONIGHT AND                 
 MONDAY AS ICE ACCUMULATIONS SHOULD BE LESS THAN 1/4 INCH AND MOST

 THIS WILL BE A SIGNIFICANT PROBLEM AS TEMPERATURES WILL NOT WARM               
 MUCH TODAY...KEEPING WESTERN PORTIONS AT OR BELOW FREEZING AS ICE              
 CONTINUES TO ACCUMULATE. ON RADAR THE RETURNS MAY NOT LOOK                     
 SIGNIFICANT BUT WITH THE TEMPERATURE AT OR BELOW FREEZING FOR SUCH             
 A LONG TIME...EVEN SMALL AMOUNTS CAN CAUSE SIGNIFICANT PROBLEMS ON             
 BRIDGES...OVERPASSES...TREES AND POWER LINES. TOTAL ICE AMOUNTS                
 THROUGH TONIGHT IN THE ICE STORM WARNING AREA WILL RANGE BETWEEN               
 ONE QUARTER AND THREE QUARTERS OF AN INCH. SOME MINOR AMOUNTS OF               
 SLEET WILL BE POSSIBLE LATER TODAY AND TONIGHT.                                
 WINTER PRECIP WILL MOVE INTO THE SOUTHERN PORTIONS LATER TONIGHT AS            
 TEMPERATURES FINALLY BEGIN TO FALL. AT THE SAME TIME...THE SYSTEM

 FINALLY START TO SHIFT EAST TODAY AS FINAL SURFACE LOW AND UPPER               
 SYSTEM SHEAR BY TO THE NW. HOWEVER STRONG UPPER RIDGE OVER THE SE              
 SHOULD BE ABLE TO AGAIN SLOW THE FRONT AND ASSOCIATED DEEP MOISTURE            
 ENOUGH TO ALLOW ANOTHER VERY MILD DAY ACROSS THE AREA. THIS SUPPORTED          
 BY MODEL RH SECTIONS WHICH INDICATE MID/HIGH CLOUDS EARLY THEN                 
 INCREASING LOW LEVEL MOISTURE BEFORE ARC OF SHRA WORKS INTO THE

 THE RIDGES WITH BEST SUPPORT EXITING NORTH WHILE INSTABILITY WELL              
 TO THE SOUTH. EXPECT BEST COVERAGE FAR WEST EARLY ON AS BAND OF                
 SHRA NUDGES EAST AND WEAKENS BEFORE JUMPING INTO THE PIEDMONT

 GRADIENT BETWEEN THE TWO SYSTEMS...AND SCATTERED TO BROKEN CANOPY OF

 FINALLY START TO SHIFT EAST TODAY AS FINAL SURFACE LOW AND UPPER               
 SYSTEM SHEAR BY TO THE NW. HOWEVER STRONG UPPER RIDGE OVER THE SE              
 SHOULD BE ABLE TO AGAIN SLOW THE FRONT AND ASSOCIATED DEEP MOISTURE            
 ENOUGH TO ALLOW ANOTHER VERY MILD DAY ACROSS THE AREA. THIS SUPPORTED          
 BY MODEL RH SECTIONS WHICH INDICATE MID/HIGH CLOUDS EARLY THEN                 
 INCREASING LOW LEVEL MOISTURE BEFORE ARC OF SHRA WORKS INTO THE

 FRONT SHOULD CROSS THE MOUNTAINS THIS EVENING AND EXIT THE COAST TUE           
 MORNING. PRE-FRONTAL MOISTURE GETS QUITE STRETCHED OUT CROSSING                
 THE RIDGES WITH BEST SUPPORT EXITING NORTH WHILE INSTABILITY WELL              
 TO THE SOUTH. EXPECT BEST COVERAGE FAR WEST EARLY ON AS BAND OF                
 SHRA NUDGES EAST AND WEAKENS BEFORE JUMPING INTO THE PIEDMONT                  
 TOWARD MORNING AS NEXT WEAK IMPULSE RIDES UP THE FRONT. THEREFORE              
 LIKELY POPS WEST AND FAR SE...WITH MAINLY CHANCE BLUE RIDGE WHERE              
 RH LOOKS LIMITED BY LEFTOVER MID LEVEL DRY AIR PER RAOBS. 85H                  
 FRONT SHOULD CHASE DOWN ANY LINGERING SHRA FAR NW TOWARD MORNING               
 WITH CHANGE TO -SHSN LIKELY BY 12Z. END OF WARMTH WILL BE MARKED

 GRADIENT BETWEEN THE TWO SYSTEMS...AND SCATTERED TO BROKEN CANOPY OF

 MODELS HAVE COME INTO GOOD AGREEMENT WITH THIS NEXT SYSTEM...AS                
 FAR AS MID AND HIGH LEVEL DYNAMICS ARE CONCERNED. THE SURFACE                  
 SYSTEM IS STILL EXPECTED TO TRACK WELL SOUTH OF WISCONSIN.                     
 HOWEVER...THE H850 BAROCLINIC ZONE IS NOW EXPECTED TO BE MAINLY                
 ACROSS NORTHERN ILLINOIS...WITH WEAK SOME WEAK OVERRUNNING INTO                
 SOUTHERN WISCONSIN.                                                            
 THE MOST SIGNIFICANT DYNAMICS WILL BE IN THE MID LEVELS WITH A                 
 PERIOD OF STRONG OMEGA CENTERED AROUND 06Z MONDAY. THERE WILL ALSO             
 BE SOME PERSISTENT MODERATE FRONTOGENETIC FORCING BETWEEN H850 AND             
 H700. THERE IS LITTLE EVIDENCE OF THETA-E RIDGING...BUT THERE                  
 SHOULD BE SOME H500 DIVERGENCE.                                                
 THE PROBLEM IS THAT THE TEMPERATURE PROFILES ARE NEARLY                        
 ISOTHERMAL...RANGING FROM AROUND -5 TO -10 FROM THE SURFACE TO                 
 AROUND 12K FEET. BUFFY IS INDICATING THAT NO ICE CRYSTALS WILL BE              
 PRESENT IN THE CLOUDS...AND TO CONSIDER FREEZING DRIZZLE. COBB                 
 WATER/SNOW RATIO IS EXPECTED TO BE AROUND 9:1 OVERNIGHT. HPC..GFS              
 AND WRF 12 HOUR QPF ARE GENERALLY IDENTICAL...THE NAM IS A BIT                 
 HIGHER. USING A 13:1 PESSIMISTIC RATIO...I CAN ONLY GET AROUND 3               
 INCHES OVERNIGHT...AND ONLY 1 INCH OR SO MONDAY MORNING. I WILL                
 HOLD OFF ON AN ADVISORY AT THIS TIME DUE TO LACK OF CONFIDENCE                 
 THAT THE SITUATION WILL DEVELOP.

 MAIN CONCERNS IN THE SHORT TERM WILL BE CLOUD COVER THROUGH TODAY...           
 AND TEMPERATURES TONIGHT AS SOME OF THE COLDEST AIR SINCE EARLY                
 DECEMBER MOVES INTO THE REGION.                                                
 SHORT TERM...TODAY THROUGH FRIDAY...                                           
 WEAK PVA AHEAD OF UPPER LEVEL TROUGH OVER IOWA HAS PROVIDED JUST               
 ENOUGH WEAK LIFT IN A RATHER SHALLOW MOIST LAYER TO KEEP FLURRIES              
 GOING OVERNIGHT ACROSS MUCH OF THE AREA.  FLURRIES OR LIGHT SNOW               
 SHOWERS WILL CONTINUE TO BE A THREAT THIS MORNING UNTIL H5 TROUGH              
 AXIS CLEARS THE AREA.  OBSERVATIONS SHOW VISIBILITIES ARE GENERALLY            
 7-10 MILES OR GREATER ACROSS THE AREA... SO ANY ACCUMULATION WILL BE           
 VERY LIGHT FROM HERE ON OUT.  THE VERY FINE AND DRY SNOW HAS BLOWN             
 ABOUT QUITE A BIT OVERNIGHT... AND ROAD TRAFFIC HAS INDUCED                    
 MELTING/REFREEZING IN SOME LOCATIONS... SO DRIVERS SHOULD BE AWARE             
 OF SLICK SPOTS.                                                                
 CLEARING LINE OF THE LOW CLOUDS IS ROUGHLY CO-LOCATED WITH THE MID             
 LEVEL TROUGH AXIS... AND IT HAS BEEN VERY SLOW MOVING... STALLED OUT           
 JUST WEST OF THE CWA ALL NIGHT.  NAM/RUC CROSS SECTIONS AND LAYER              
 RH/WIND PLOTS SUGGEST KEEPING THE LOW CLOUDS ACROSS MUCH OF THE CWA            
 THROUGH NOON TIME... WITH GRADUAL CLEARING WEST OF I-55 EARLY IN THE           
 AFTERNOON... WITH CLOUDS LINGERING UNTIL EARLY EVENING IN FAR                  
 EASTERN ILLINOIS.  SO WHILE IT IS TEMPTING TO GO WITH A MORE                   
 OPTIMISTIC SKY FORECAST WITH THE CLEARING LINE SO CLOSE... WILL KEEP           
 THINGS PESSIMISTIC.  SATELLITE OBS OVER MISSOURI ACTUALLY SUGGEST              
 THE CLOUDS ARE REDEVELOPING IN BANDS PARALLEL WITH THE LOW LEVEL               
 FLOW... THESE BANDS EVEN SHOW UP WELL IN 88D DATA FROM KLSX.                   
 CLEARING WILL COME IN OVERNIGHT... BRINGING SOME OF THE COLDEST                
 WEATHER WE HAVE SEEN SINCE EARLY DECEMBER... AND CLEARLY THE COLDEST           
 OF THE YEAR SO FAR.  RECENT TRACES AND MINOR ACCUMULATIONS OF DRY              
 SNOW ARE NOT EXPECTED TO HAVE MUCH IMPACT ON LOW TEMPS TONIGHT.                
 WINDS WILL BE LIGHTEST WEST OF I-55 WHERE THE SFC RIDGE AXIS WILL              
 SET UP.  UPSTREAM TEMPERATURES THIS MORNING OVER EASTERN IOWA HAVE             
 BEEN MORE INFLUENCED BY THE LIGHT SNOW PACK IN THOSE REGIONS... AND            
 THUS DO NOT EXPECT OUR TEMPERATURES TONIGHT TO BE QUITE SO LOW.                
 EXPECT A SLOW WARMING TREND WED-THU AS HIGH PRESSURE SETTLES OFF TO            
 OUR EAST.  HAVE DECREASED MAX TEMPS ON WEDNESDAY AS HIGH PRESSURE              
 REMAINS MORE OR LESS OVERHEAD THROUGH THE AFTERNOON... WITH SFC                
 WINDS NOT REALLY SHIFTING UNTIL EVENING.  ANY WAA JUST ALOFT WILL              
 LIKELY HAVE A HARD TIME MIXING DOWN TO THE SFC WITH STRONG                     
 SUBSIDENCE INVERSION IN PLACE.                                                 
 A WEAK CLIPPER SYSTEM WILL APPROACH FRIDAY INTO FRIDAY NIGHT... AND            
 WHILE SOME SCATTERED FLURRIES CANNOT BE COMPLETELY RULED OUT...                
 CHANCES ARE STILL TOO LOW TO MENTION IN THE FORECAST THIS FAR OUT.             
 THE GFS IS NOW IN AGREEMENT WITH THE ECMWF IN DEFLECTING THE SECOND            
 ARCTIC INTRUSION BEHIND THE CLIPPER WELL TO OUR EAST... BUT TEMPS              
 WILL DIP AGAIN BY THE WEEKEND... WITH SOME REMAINING CLOUD COVER AND           
 A COOL NORTHWEST WIND.  HOWEVER... TEMPERATURES WILL BE ONLY A                 
 LITTLE BELOW NORMAL IN THIS TIME FRAME.                                        
 LONG TERM...SATURDAY THROUGH MONDAY...                                         
 LONGER RANGE SOLUTIONS SUGGEST WE WILL REMAIN IN THIS COOLER/NEAR              
 NORMAL PATTERN EVEN OUT THROUGH DAY 10... AS H5 LOW REMAINS ANCHORED           
 OFF BAFFIN ISLAND... WITH THE MEAN LONGWAVE TROUGH POSITION ACROSS             
 THE NORTHEASTERN CONUS.                                                        
 THE +72 HR AND +240 HR ECMWF H5 PLOTS... VALID THIS AND NEXT                   
 THURSDAY NIGHT... LOOK ALMOST IDENTICAL.                                       
 NEXT CHANCE FOR PRECIP WILL COME TOWARDS SUN/MON AS A CUTOFF LOW               
 CURRENTLY PINCHING OFF OVER THE DESERT SOUTHWEST... EJECTS                     
 EASTWARD.  WITH TEMPERATURES NEAR OR JUST BELOW NORMAL... WINTRY               
 PRECIP MAY BE A THREAT... BUT AT THIS POINT NO MAJOR STORMS APPEAR             
 TO BE ON THE HORIZON.  WILL NEED TO KEEP AN EYE ON EJECTING CUTOFF             
 LOW TO SEE IF IT CAN MANAGE TO PHASE WITH SOME NORTHERN STREAM                 
 ENERGY WHICH MAY BE MORE CONDUCIVE TO SFC CYCLOGENESIS.                        
 BEYOND THAT... WE REMAIN IN THE SAME FAMILIAR PATTERN AS THIS                  
 WEEK... WITH PERIODIC INTRUSIONS OF COLD AIR MAINLY SCRAPING BY TO             
 OUR EAST.  THE GFS IN THE LONGER TERM IS QUITE A BIT COLDER FOR US             
 THAN THE ECMWF AS IT BRINGS DOWN THE ARCTIC AIR ACROSS THE MIDWEST             
 INSTEAD OF THE EAST COAST... BUT THE GFS EARLIER PREDICTED THE SAME            
 THING FOR THIS WEEK... AND ONLY IS JUST NOW CATCHING UP WITH THE               
 ECMWF.

 FORECAST CONCERN IN THE SHORT TERM REVOLVES AROUND LAKE EFFECT SNOW            
 POTENTIAL LATER THIS EVENING THROUGH TUE AFTERNOON. FIRST...OUTSIDE            
 OF LAKE EFFECT AREAS A BAND OF SNOW IS MOVING THROUGH THE N/NW                 
 PORTION OF THE CWA THIS AFTERNOON ALONG FIRST OF SEVERAL SECONDARY             
 COLD FRONTS. THE TRUE ARCTIC FRONT LIES OVER SOUTHERN WISCONSIN AND            
 CENTRAL LOWER MICHIGAN WITH REGIONAL RADARS SHOWING ANOTHER BAND OF            
 ENHANCED SNOW ALONG AND BEHIND THIS FEATURE. ALSO A LARGE AREA OF              
 LIGHT SNOW ASSOCIATED WITH DECAYING DEFORMATION AXIS UPSTREAM FROM             
 NORTHERN ILLINOIS INTO LOWER MICHIGAN. GIVEN LOOK OF UPSTREAM RADARS           
 AND EXPECTED PASSAGE OF MID LEVEL TROUGH AXIS AND ASSOCIATED LIFT...           
 MAY SEE A GENERAL LIGHT SNOWFALL ACROSS MOST OF THE CWA TONIGHT.               
 WILL PROBABLY END UP GOING WITH LOW LIKELY POPS AND A COATING OF               
 ACCUMS IN MOST AREAS...EXCEPT FOR THE FAR SOUTH.                               
 NOW FOR THE LAKE EFFECT. FORECAST SURFACE PRESSURE FIELDS SHOW A               
 CLASSIC PATTERN RECOGNITION FOR A BIG SOUTHERN LAKE MICHIGAN EVENT             
 WITH A 1040+MB ARCTIC HIGH BUILDING SOUTH DOWN THE PLAINS. UPSTREAM            
 RADARS SHOWING HEALTHY BANDS OF LAKE EFFECT SNOW DEVELOPING ON                 
 NORTHERLY FETCH OF LAKE SUPERIOR AND ANOTHER OFF GREEN BAY AFFECTING           
 THE DOOR PENINSULA. LAST FEW RUNS OF THE NAM-WRF AND THE FSL                   
 EXPERIMENTAL 13KM RUC HAVE BEEN REASONABLY CONSISTENT IN DEVELOPING            
 A WELL DEFINED SINGLE BAND TONIGHT DOWN THE LONG AXIS OF LAKE                  
 MICHIGAN. INSTABILITY IS VERY GOOD WITH LAKE INDUCED CAPES EXCEEDING           
 500J/KG AND EQUILIBRIUM LEVELS ABOVE 700MB. CLOUD BEARING LAYER AND

 INTERSECTING THE FAVORED DENDRITIC SNOW GROWTH ZONE. MESOSCALE

 AWHILE TONIGHT...WHICH IS A CLASSIC HALLMARK OF OUR BIG EVENTS AT              
 THE SOUTH END OF LAKE MICHIGAN. CONVERGENCE ALREADY BEGINNING TO               
 DEVELOP DOWN THE AXIS OF THE LAKE AS NOTED IN SURFACE OBS ALONG THE            
 E AND W SHORELINES...AND NAM-WRF STRENGTHENS LOW LEVEL CONVERGENCE             
 FIELD AS IT ARCS CYCLONICALLY INTO NW INDIANA AND SW LOWER MICHIGAN.           
 ALL SIGNS POINT TOWARDS THE POTENTIAL OF A MAJOR LAKE EFFECT SNOW              
 EVENT...WHICH HAS BEEN A RARITY AROUND HERE THE PAST FEW SEASONS

 SEE A RATHER INTENSE BAND ACROSS PARTS OF LAPORTE...STARKE...                  
 MARSHALL...AND KOSCIUSKO COUNTIES...HOWEVER EXPECT THE BAND TO                 
 REMAIN TRANSIENT THROUGH THESE COUNTIES AND NOT STAY OVER ONE SPOT             
 LONG ENOUGH TO DROP WARNING CRITERIA. IF IT BECOMES APPARENT THAT              
 THE BAND WILL GO STATIONARY FOR SEVERAL HOURS OVER ONE OF THESE                
 COUNTIES THAN AN UPGRADE MAY BE NEEDED. EXPECT THE MAJOR SINGLE BAND           
 TO BREAK APART INTO MULTIPLE BANDS...WEAKEN...AND SPREAD EAST ON TUE           
 AFTERNOON AS FLOW BACKS AND SYNOPTIC SCALE SUBSIDENCE INCREASES.

 TAKING A LOOK AT THE WATER VAPOR IMAGERY THIS MORNING...MUCH OF THE            
 NATION WAS RELATIVELY DRY.  IN GENERAL...ALL BUT THE EASTERN THIRD             
 OF THE NATION WAS UNDER THE INFLUENCE OF HIGH PRESSURE.  THERE WERE            
 THREE SURFACE LOWS OF NOTE THIS MORNING.  THE FIRST WAS THE EXITING            
 LOW PRESSURE SYSTEM...CENTERED OVER JUST OFF THE NEW ENGLAND                   
 COAST...WITH A COLD FRONT STRETCHING THROUGH THE CAROLINAS AND                 
 NORTHWESTERN FLORIDA.  THE SECOND...SLIGHTLY WEAKER LOW WAS SITUATED           
 OVER THE NORTHWEST TERRITORIES UP IN CANADA.  THIS FEATURE HAD A               
 WARM FRONT DROPPING SOUTH THROUGH SASKATCHEWAN AND EASTERN MONTANA.            
 WARMER TEMPERATURES WERE NOTED ACROSS NORTHERN MONTANA.  FOR                   
 EXAMPLE...THE 09Z TEMPERATURE AT CUT BANK MONTANA WAS 28                       
 DEGREES...WHILE CLOSER TO HOME THE TEMPERATURE WAS -16 AT                      
 INTERNATIONAL FALLS.  LOOKING HIGHER UP INTO THE ATMOSPHERE...AND              
 THE WATER VAPOR IMAGERY AND RUC...THE MID LEVEL TROUGH WAS SET UP              
 FROM EASTERN LAKE SUPERIOR THROUGH THE SOUTHERN TIP OF THE UPPER               
 PENINSULA...AND DOWN THROUGH IOWA...ALL THE WAY THROUGH SOUTHERN               
 ARIZONA.                                                                       
 CONTINUE TO BE CONCERNED WITH LAKE EFFECT SNOW ACROSS OUR THE                  
 CENTRAL AND EASTERN LAKE SUPERIOR SHORELINE TODAY.  THE BANDS OF               
 SNOW HAVE BEEN CONTINUING THE SLOWLY SHIFT EASTWARD OVERNIGHT AS               
 WINDS HAVE BECOME MORE NORTHWESTERLY...INCREASING THE CONVERGENCE              
 ACROSS THIS AREA.  WAS ORIGINALLY CONCERNED WITH THE AMOUNT OF DRY             
 AIR THAT WILL COME INTO THIS AREA WITH OF CENTRAL...WESTERN...AND              
 NORTHERN LAKE SUPERIOR CLOUD FREE EARLIER THIS MORNING.  FURTHER TO            
 OUR WEST...DEW POINTS ARE IN THE UPPER TEENS TO MID 20S BELOW ZERO.            
 ACROSS THE CWA DEW POINTS WERE STILL IN THE SINGLE DIGITS ABOVE                
 ZERO.  EVEN WITH THIS DRIER AIR FILTERING IN...THE NNW TO SSE CLOUDS           
 HAVE DEVELOPED FAIRLY NICELY OVER THE PAST SEVERAL HOURS ACROSS THE            
 EASTERN HALF OF THE LAKE.  THE BETTER FETCH FOR LAKE EFFECT WAS ALSO           
 EXPECTED TO OFFSET SOME OF THIS DRY AIR.  EVENING SHIFT DID HOIST              
 ADVISORIES FOR ALGER COUNTY EASTWARD THOUGH THIS EVENING.  3-5KFT              
 INVERSION HEIGHTS...GOOD MOISTURE AROUND THE SNOW GROWTH REGION                
 SHOULD ALLOW FOR ADVISORY CRITERIA THROUGH THIS EVENING.                       
 WARM AIR WILL SURGE EASTWARD INTO THE UPPER PENINSULA DURING THE DAY           
 WEDNESDAY AS THE WARM FRONT OVER NORTHEASTERN MONTANA SWINGS OUR WAY           
 AND THE 500MB RIDGE SLIDES OVERHEAD.  850MB TEMPERATURE SHOULD                 
 RISING TO THE -1 TO -3 RANGE BY 00Z THURSDAY.  WITH THIS SAID...AM             
 HESITANT TO DECREASE CURRENT FORECAST TEMPERATURES ANY...EVEN GIVEN            
 SLIGHTLY COOLER TEMPS FROM THE GFS/MAV WITH MORE CLOUDS                        
 ANTICIPATED.  SO...FEW CHANGES WERE MADE TO TEMPS FOR MID WEEK.

 VFR CONDITIONS AT MBS WILL SPREAD SLOWLY SOUTHWARD TOWARD FNT

 PATCHES OF LIGHT SNOW AND FLURRIES OVER SOUTHERN LOWER MICHIGAN                
 WERE STRONGLY DEPENDENT ON LOW LEVEL CONVERGENCE ASSOCIATED WITH               
 THE TROUGH SHOWN ON THE SURFACE ANALYSIS. THIS ACTIVITY WILL                   
 CONTINUE TO WEAKEN OVERNIGHT AS THE TROUGH FILLS AND HIGH PRESSURE             
 BUILDS MORE STRONGLY INTO THE REGION.

 THE AREA OF LIGHT SNOW OVER SOUTHERN LOWER MICHIGAN WAS WEAKENING              
 AS THE MID LEVEL DEFORMATION SHEARED APART WHILE SLIDING EASTWARD.             
 EXPECT THIS TREND TO CONTINUE AND LEAVE BEHIND COLD NORTHERLY LOW              
 LEVEL FLOW THAT WILL HEIGHTEN LAKE EFFECT POTENTIAL IN THE THUMB               
 FOR A FEW HOURS.                                                               
 THE LATEST OBSERVATIONS SHOWED A NICE AREA OF WIND CONVERGENCE                 
 COMING INTO THE THUMB BETWEEN GRAVELLY SHOAL AND HARBOR BEACH.                 
 COMBINE THIS WITH COLD ADVECTION TAKING 850 MB TEMPS DOWN TO ABOUT             
 -15C BY 06Z AND EQUILIBRIUM LEVELS RISING TO ABOUT 750MB/7000 FEET

 3 INCHES APPEARS ON TARGET CONSIDERING THE BRIEF NATURE OF THE                 
 EVENT WITH THE WINDS TURNING TOWARD THE NW BY 09Z DRIVING LAKE

 WITH OUR RECENT STORM TRACKING EAST OF THE GREAT LAKES...RESIDUAL              
 DEFORMATION AXIS OF SNOW WILL MOVE ACROSS THE REGION THIS EVENING.             
 CROSS SECTIONS NICELY DEPICT THIS DEFORMATION ZONE CENTERED BETWEEN            
 600-700MB WITH VISIBILITIES UNDER THE BAND OF SNOW DROPPING TO LESS            
 THAN 1 MILE.  IN FACT...SOME LAKE HURON CONTRIBUTION IS NOTED WITH A           
 NARROW BAND OF SNOW COMING DOWN ACROSS SAGINAW BAY INTO MBS WITH 1/4           
 MILE VISIBILITY.  LATEST RUC INCLUDING THE 12Z MODEL SUITE SUGGEST             
 THE 1000-850MB WIND WILL BACK TOWARD THE NORTH THIS EVENING AS THIS            
 DEFORMATION AXIS SWINGS SOUTH-SOUTHEAST ACROSS THE STATE.  SPECIFIC            
 HUMIDITIES ARE RUNNING AROUND 1 G/KG AND ACCUMULATIONS COULD ADD UP            
 TO ANOTHER 1 INCH NORTH OF M59 THIS EVENING.  FURTHER SOUTH...WITH             
 THE BOUNDARY LAYER BECOMING MORE NORTHERLY...EXPECT SOME DOWNSLOPING           
 INFLUENCES TO REDUCE THE SNOWFALL AMOUNTS AND DEFORMATION AXIS                 
 WEAKENING AS THE SURFACE TROUGH AND UPPER LEVEL TROUGH SWING                   
 SOUTHEAST OF THE STATE.  THEN THE REAL COLD ADVECTION TAKES SHAPE              
 TONIGHT WITH CONCERN SHIFTING TOWARD LAKE EFFECT SNOW FOR PORTIONS

 BOTH THE NAM AND GFS ARE IN RATHER GOOD AGREEMENT WITH THE                     
 1000-850MB FLOW WHICH IS RATHER PERSISTENT (360 DEGREES) FOR MOST OF           
 THE NIGHT.  TOWARD 09Z-12Z...FLOW BACKS A LITTLE MORE TAKING THE               
 BAND OFFSHORE BUT STILL TOUCHING THE M10 CORRIDOR IN HURON COUNTY.             
 INVERSION HEIGHTS CLIMB...PER BUFKIT PROFILES...FROM NEAR 850MB TO             
 BETWEEN 800-750MB WITH LAKE INDUCED CAPES CLIMBING TOWARD 300 J/KG             
 AND LAKE DELTA T/S INTO THE MIDDLE TEENS CELSIUS.  925MB CONVERGENCE           
 AND OMEGA FIELDS LOOK RATHER IMPRESSIVE ACROSS HURON...SANILAC AND             
 TOUCHING NORTHEAST ST CLAIR COUNTY OVERNIGHT SO ADDITIONAL SNOWFALL            
 IS EXPECTED.  LOCAL DECISION TREE SUGGESTS ANOTHER 2-4"/12HRS BUT              
 WITH THE BAND MOVING OFFSHORE...WILL CUT THOSE VALUES TO ANOTHER               
 1-3" AND MENTION BRIEF PERIODS OF HEAVY SNOW IN THE FORECAST/GRIDS.            
 WEATHER DOES QUIET DOWN ON TUESDAY WITH A COLD NORTHERLY FLOW AND              
 MOISTURE DECREASING.  THIS SHOULD ALLOW FOR SOME SUNNY BREAKS YET              
 THAT COULD HELP STEEPEN THE LOW LEVEL LAPSE RATES...AND WOULD NOT BE           
 SURPRISED TO SEE SOME LIGHT SNOW SHOWERS MOVING ACROSS THE CWA.                
 WILL KEEP THE LOW POPS FOR MOST AREAS AWAY FROM LAKE HURON...AS LAKE           
 BAND COULD STILL IMPACT THE M10 CORRIDOR IN HURON COUNTY.                      
 TEMPERATURES WILL BE QUITE CHILLY (OR SEASONABLE) TONIGHT AND                  
 TUESDAY WITH LOWS TONIGHT DROPPING BACK INTO THE TEENS.  ON TUESDAY

 ONE WORD CAN PRETTY MUCH SUM UP CURRENT CONDITIONS...COLD. A 1036MB            
 SURFACE HIGH PARKED OVER THE REGION AND ASSOCIATED CLEAR SKIES AND             
 CALM WINDS HAVE TEAMED UP WITH THE FRESH SNOW COVER TO PRODUCE                 
 BITTERLY COLD TEMPERATURES. TEMPERATURES ACROSS THE CWA CURRENTLY              
 RANGE FROM 1 ABOVE TO 12 BELOW ZERO. EARLY MORNING WATER VAPOR                 
 IMAGERY AND RUC UPPER AIR ANALYSIS DATA SHOW THAT THE UPPER WAVE               
 THAT BROUGHT US THE LAST ROUND OF ACTIVE WEATHER HAS SLID                      
 EAST...WITH A STRAIGHT NORTHERLY FLOW PREVAILING ALOFT ACROSS THE              
 NORTHERN AND CENTRAL PLAINS BETWEEN THE DEPARTED WAVE AND A                    
 SHORTWAVE RIDGE OVER THE NORTHERN ROCKIES. STRONG SUBSIDENCE IS                
 FIRMLY IN PLACE OVER THE NORTHERN AND CENTRAL PLAINS...AS EVIDENCED            
 BY THE 1036MB SURFACE HIGH AND CLEAR SKIES.                                    
 A FAIRLY QUIET WEATHER PATTERN WILL CONTINUE ACROSS THE AREA THE               
 NEXT FEW DAYS. WEAK SOUTHWEST RETURN FLOW DEVELOPS BY AFTERNOON AS             
 THE SURFACE HIGH PUSHES SOUTHEAST WHILE UPPER RIDGING BUILDS EAST              
 INTO THE REGION. WE/LL ALSO SEE AMPLE SUNSHINE AGAIN TODAY.                    
 HOWEVER...STILL EXPECT ONLY MARGINAL IMPROVEMENT IN TEMPERATURES               
 GIVEN A VERY COLD START TO THE DAY...SNOW COVER...LIGHT WINDS...AND            
 VERY LIMITED MIXING. H85 TEMPS DO WARM SEVERAL DEGREES FROM                    
 YESTERDAY...BUT IT WILL BE DIFFICULT TO REALIZE MUCH OF THIS AT THE            
 SURFACE GIVEN LITTLE MIXING. HAVE STAYED WAY BELOW MOS GUIDANCE AND            
 MODEL 2M TEMPS WHICH ARE CURRENTLY RUNNING AROUND 10 DEGREES TOO               
 WARM COMPARED TO ACTUAL TEMPS. CLEAR SKIES CONTINUE INTO TONIGHT AND           
 ALTHOUGH IT WILL BE ANOTHER COLD ONE...SOUTHERLY SURFACE WINDS STAY            
 UP SOME WHICH SHOULD KEEP MIN TEMPS NOTABLY WARMER THAN CURRENT                
 READINGS.                                                                      
 THE UPPER FLOW TURNS SOUTHWEST ON WEDNESDAY AS A SHORTWAVE TRACKS              
 ACROSS THE CENTRAL ROCKIES AND PLAINS. MEANWHILE LOW-LEVEL SOUTHERLY           
 FLOW INTENSIFIES IN A TIGHTENING GRADIENT BETWEEN A DEEPENING LEE              
 TROUGH AND SURFACE HIGH TO THE EAST. ASSOCIATED WARM AIR ADVECTION             
 SHOULD BE SUFFICIENT TO PUSH DAYTIME TEMPS INTO THE 20S F. THE WAVE            
 WILL BRING SOME INCREASE IN CLOUDS BUT NOTHING IN THE WAY OF PRECIP.           
 A CLIPPER SYSTEM THEN SENDS A COLD FRONT THROUGH THE CWA WEDNESDAY             
 NIGHT. SHOULD SEE AN AN ASSOCIATED INCREASE IN CLOUDS...WHICH WILL             
 HELP HOLD TEMPS UP COMPARED TO PREVIOUS COUPLE OF NIGHTS. COLD AIR             
 ADVECTION WILL STALL THE GRADUAL WARMING TREND...WITH TEMPS ON                 
 THURSDAY EXPECTED TO REMAIN IN THE MID 20S TO LOWER 30S FOR HIGHS.             
 THIS SYSTEM CONTINUES TO LOOK MOISTURE STARVED SO WILL MAINTAIN THE            
 DRY FORECAST WEDNESDAY NIGHT AND THURSDAY.                                     
 NO NOTEWORTHY CHANGES WERE MADE TO THE EXTENDED...BUT THE MAIN                 
 FEATURE OF INTEREST DURING THIS PERIOD IS ANOTHER SOUTHWEST CUTOFF             
 LOW WHICH COULD BE A PLAYER IN OUR WEATHER OVER THE WEEKEND.                   
 FORECAST TRACKS FROM LATEST OPERATIONAL MODEL RUNS SUGGEST SOUTHERN            
 PORTIONS OF THE CWA AND POINTS SOUTH WOULD SEE THE GREATEST IMPACT             
 FROM THIS SYSTEM...BUT ENSEMBLE DATA SHOWS A LOT OF UNCERTAINTY                
 EXISTS WITH THE EVOLUTION OF THIS SYSTEM AS WOULD BE EXPECTED AT               
 THIS POINT. THIS WILL BEAR CLOSE WATCHING IN THE DAYS TO COME.

 WEST OF KSBN BUT MAKING ITS WAY BACK EAST. THIS WILL LIKELY CONTINUE           
 INTO THE EARLY AFTERNOON AS NAM12 925MB PLUME ANALYSIS KEEPS GOOD

 AS EXPECTED...TYPE I LAKE EFFECT SNOW BAND HAS SET UP DOWN THE LONG            
 AXIS OF LAKE MICHIGAN. AT 08Z...GOES 3.9-11 MICRON SHOWS IMPRESSIVE            
 BAND THAT HAS UPSTREAM CONNECTION TO LAKE SUPERIOR. THIS                       
 PRECONDITIONING SHOULD HELP OVERCOME SLIGHTLY DRIER AIR WORKING                
 ACROSS WISCONSIN EARLY THIS MORNING. NAM-WRF 925MB PLUME ANALYSIS              
 HAS HAD A GOOD HANDLE ON THE SITUATION AND ALONG WITH FSL RUC13 HAVE           
 BEEN USED FOR MOST OF THIS FORECAST PACKAGE.                                   
 OVERALL...CURRENT FORECAST IS IN GOOD SHAPE. QUESTIONS REMAIN WITH             
 HOW FAR EAST THE MEANDERING BAND WILL MOVE AND HOW MUCH SNOW FAR               
 NORTHEAST LAPORTE COUNTY WILL RECEIVE. NAM-WRF 925MB OMEGA FIELDS              
 SUGGEST THIS BAND WILL BECOME NEARLY STATIONARY FROM BRIDGMAN TO               
 SOUTH BEND AND INTO NORTHERN MARSHALL COUNTY. FROM THERE...SOUTHERN            
 END LOOKS TO MOVE ABOUT ACROSS KOSCIUSKO AND SOUTHERN MARSHALL                 
 COUNTIES. SO FAR...THIS HAS BEEN PLAYING OUT WELL WITH 08Z RADAR               
 RETURNS SHOWING HEAVIEST SNOW ALONG THE BRIDGMAN TO SBN LINE. HAVE             
 BEEN DECENT RETURNS ACROSS NORTHEAST LAPORTE COUNTY WITH REPORTS OF            
 2 INCHES AROUND 07Z IN ROLLING PRAIRIE. SO FAR...THE MODELS WESTWARD           
 BIAS APPEARS TO BE RATHER SMALL...MAYBE ONLY 5 TO 10 MILES. BANDS              
 ARE FINALLY MAKING THEIR WAY INTO SOUTHWEST CASS AND EXTREME                   
 NORTHWEST ELKHART COUNTY. AT THIS TIME...IT DOES LOOK LIKE THE MAIN            
 BAND WILL BE SLIGHTLY EAST OF STRONGEST OMEGA DEPICTION ON                     
 NAM-WRF...JUST GETTING IT INTO WESTERN PORTIONS OF THESE COUNTIES.             
 RADAR RETURNS FROM KLOT AND TMDW SUGGEST A SECOND NARROW BAND WILL             
 PERSIST JUST TO THE WEST OF MAIN BAND. THIS WILL AFFECT MAINLY FAR             
 SOUTHERN BERRIEN AND NORTHERN LAPORTE COUNTIES. CONCERNED THAT FAR             
 NORTH AND NORTHEAST LAPORTE COUNTY WILL EXCEED 6 INCHES THIS                   
 MORNING. CONTEMPLATING ADDING TO THE WARNING. REMAINDER OF WARNING             
 AND ADVISORY AREA EXPECTED TO STAY THE SAME. WILL BREAK OUT CASS AND           
 ELKHART COUNTIES TO ENHANCE WORDING FOR WESTERN PORTIONS.                      
 MOISTURE BEGINS TO WANE DURING THE DAY AS 1040MB HIGH IN THE PLAINS            
 NUDGES EAST. LIKE THE NAM-WRF DEPICTION OF LAKE AGGREGATE TROUGH               
 REMAINING OVER LAKE MICHIGAN THIS EVENING AND WEST TO SOUTHWEST FLOW           
 COUPLED WITH DELTA T VALUES IN THE UPPER TEENS TO KEEP STRATUS AND             
 SOME LIGHT SNOW SHOWERS OR FLURRIES AROUND. DID TRIM POPS BACK AWAY            
 FROM THE LAKE BASED ON 925MB FORECAST OF TRAJECTORIES AND RH FIELDS.           
 CONTINUED TO CUT MOS TEMPS AWAY FROM LAKE WHERE SKIES WILL CLEAR               
 TONIGHT. SHOULD SEE AREAS DIP WELL INTO TEENS AND POSSIBLY SOME

 WEDNESDAY THROUGH MONDAY...OVERALL...ONGOING GRIDS/ZFP APPEAR ON               
 TRACK...SO DID NOT MAKE ANY SIGNIFICANT CHANGES THIS PERIOD. AS HAS            
 BEEN THE CASE FOR MOST OF THIS WINTER SO FAR...THE LONGWAVE TROF               
 WILL NOT BE ABLE TO BECOME ESTABLISHED OVER THE MIDWEST IN THE                 
 CURRENT HIGHLY PROGRESSIVE PATTERN. IN THE BEGINNING OF THIS                   
 PERIOD...WARM AIR ADVECTION INCREASES RAPIDLY WEDNESDAY AS THE                 
 SURFACE HIGH MOVES EAST OF THE AREA. TEMPERATURES SHOULD RECOVER TO            
 NEAR NORMAL WEDNESDAY AND THURSDAY. UNLIKE THE LAST SYSTEM...NOT               
 MUCH MOISTURE WILL BE ABLE TO ADVECT INTO THE AREA...SO JUST KEPT              
 LAKE EFFECT SNOW SHOWERS FRIDAY THROUGH SATURDAY IN THE COLDER AIR.            
 THE GFS HAS ALREADY BEGUN TO RETREAT WITH THE VERY COLD AIR                    
 SATURDAY...WHICH IS REFLECTED IN THE MEX MOS HIGHS AT OR ABOVE                 
 FREEZING AT FWA FROM FRIDAY THROUGH MONDAY. THE ECMWF IS VERY

 FROM MUCH OF EASTERN CANADA DOWN THROUGH THE GREAT LAKES TO THE                
 CENTRAL PLAINS. FURTHER UPSTREAM WE SEE LONGWAVE RIDGING OVER MUCH             
 OF THE WEST. THIS RIDGING IS BEGINNING TO BREAK DOWN AS POTENT                 
 SHORTWAVE ENERGY APPROACHES THE PACIFIC NORTHWEST. AT THE SURFACE WE           
 SEE A COLD FRONT STRETCHING FROM JUST OFF THE NORTHEAST COAST DOWN             
 THE I-95 CORRIDOR TO THE NORTHERN FLORIDA PENINSULA. THIS FRONT WILL           
 USHER IN A TRUE FEEL OF WINTER TO MUCH OF THE EASTERN PORTION OF THE           
 COUNTY.

 EARLY AFTERNOON HOURS. TEMPERATURES STARTING OUT IN THE UPPER                  
 50S AND 60S HAVE FALLEN OFF DURING THE PAST SEVERAL HOURS BACK INTO            
 THE LOWER AND MIDDLE 50S MANY LOCATIONS AND EVEN SOME UPPER 40S                
 ACROSS SOUTHEASTERN ALABAMA. TEMPERATURES STILL HOLDING UP ACROSS              
 THE FAR SOUTHEAST BIG BEND BUT EVEN HERE TEMPERATURES WILL TAKE A              
 TUMBLE DURING THE EVENING. PLENTY OF CLOUDCOVER SEEN BEHIND THE                
 FRONT WITH SCATTERED SHOWERS/AREAS OF LIGHT RAIN. THIS PRECIP                  
 CONTINUES ON THE LIGHT SIDE AND IS HAVING ITS BIGGEST IMPACT ON

 EAST OF THE FORECAST AREA THIS EVENING WITH COOL AIR ADVECTING                 
 INTO ALL OF THE REGION ON NORTHERLY WINDS. CONTINUING TO SEE AREAS             
 OF LIGHT RAIN ALONG AND BEHIND THE FRONT AND THESE AREAS WILL BE               
 AROUND THROUGH THE EVENING HOURS. RECENTLY HAVE SEEN A BIT MORE                
 CONCENTRATED AREA OF LIGHT RAIN DEVELOP TO THE WEST OF OUR AREA AND            
 WILL NEED TO WATCH THIS AREA JUST IN CASE POPS NEED TO BE BUMPED UP            
 ACROSS THE WESTERN ZONES. GUIDANCE IS IN GOOD AGREEMENT ON                     
 DECREASING RAIN COVERAGE BY LATE THIS EVENING AND WOULD EXPECT THIS            
 AREA TO SHRINK WITH TIME. DYNAMICS FOR THE PRECIP REMAIN VERY WEAK.            
 STILL APPEARS THAT WE ARE SEEING JUST ENOUGH LARGE SCALE LIFT FROM             
 WEAK DEEP LAYER Q-VECTOR CONVERGENCE AND ASSOCIATED UPPER LEVEL                
 DIVERGENCE IN RIGHT ENTRANCE REGION OF 300MB 150+ KNOT JET CUTTING             
 THROUGH THE TENNESSEE/SOUTHERN OHIO VALLEYS. MAIN AREAS OF PRECIP              
 SHOULD DIMINISH WITH TIME AS THESE FEATURES LIFT OUT TO THE                    
 NORTHEAST LATER THIS EVENING AND OVERNIGHT.                                    
 THE NEXT COUPLE OF DAYS WILL BE ON THE COOL SIDE COMPARED TO THE               
 GENERAL RECENT WARMTH. ALTHOUGH DAYTIME HIGHS WILL BE ON THE COOL              
 SIDE WEDNESDAY AND THURSDAY...DIURNAL RANGES WILL BE KEPT SMALL WITH           
 ABUNDANT CLOUDCOVER...SHOWER CHANCES AND LOW LEVEL WINDS. NIGHTTIME            
 LOWS WILL GENERALLY BE IN THE UPPER 30S TO LOWER 40S NORTH AND                 
 IN THE LOWER TO MIDDLE 40S SOUTH.

 COAST OF FLORIDA WEDNESDAY NIGHT AND THEN CLOSING OFF DURING                   
 THURSDAY MORNING. CONFIDENCE IN THIS FEATURE IS A LITTLE LOWER THAN            
 AVERAGE...ESPECIALLY WITH THE PRECIP FIELDS. GFS IS SHOWING A RATHER           
 CONCENTRATED AREA OF RAIN ACROSS OUR GA ZONES WEDNESDAY NIGHT INTO             
 THURSDAY MORNING. UNDERCUT GFS POPS BY QUITE A BIT WITH THIS                   
 FORECAST PACKAGE AS WOULD EXPECT THE NORTHEAST FLOW TO CONTINUE                
 ADVECTING RELATIVELY DRY LOW LEVEL AIR INTO THE REGION AND DECREASE            
 RAIN COVERAGE AND AMOUNTS. WILL GO GENERALLY WITH CHANCE POPS FOR              
 THE EASTERN HALF OF THE AREA WITH HIGH CHANCE POPS ACROSS                      
 SOUTH-CENTRAL GA FOR THE TIME BEING. OTHER LOW CONFIDENCE ITEM WITH            
 THIS FEATURE WILL BE THE IMPACT ON TEMPERATURES FOR MAINLY OUR GA              
 ZONES. IF THE DRY AIR ADVECTION MENTIONED ABOVE IS IN PLACE WITH               
 SOME LIGHT PRECIP FIELDS...THEN TEMPERATURES LATE WEDNESDAY NIGHT              
 INTO THURSDAY MAY BE COOLER THAN ADVERTISED IN OUR GRIDS AS WET-BULB           
 EFFECTS TAKE PLACE. AT THE MOMENT WE HAVE HIGHS AROUND 50 FAR NORTH            
 TO LOWER AND MIDDLE 50S SOUTH. COULD SEE THINGS AN ADDITIONAL 5+               
 DEGREES COOLER IF EVERYTHING COMES TOGETHER JUST RIGHT.                        
 ANY SHOWERS ASSOCIATED WITH THE EAST COAST SYSTEM WILL BE PULLING              
 AWAY DURING THURSDAY AFTERNOON WITH SOME BREAKS OF SUN LIKELY ACROSS           
 OUR WESTERN/SOUTHERN ZONES. WEAK HIGH PRESSURE THEN TRIES TO BUILD             
 IN FOR THURSDAY NIGHT AND FRIDAY AS MID/UPPER LEVEL SHORTWAVE ENERGY           
 DIVES INTO THE SOUTHEAST.

 (FRIDAY NIGHT-MONDAY) THE SHORTWAVE TROF MOVING THROUGH ON FRIDAY              
 NIGHT APPEARS TO BE STRONG ENOUGH TO CLEAR THE REGION TO PRODUCE A             
 BREAK IN THE UNSETTLED WX OVER MUCH OF THE WEEKEND...ALTHOUGH THE              
 SFC RIDGE BEHIND THE NEXT COLD FRONT DOES APPEAR TO BE SUBSTANTIALLY           
 WEAKER. THIS IS NOW SUPPORTED BY BOTH THE GFS AND ECMWF...WHICH ALSO           
 SHOW THE NEXT LOW HEADING OUR WAY ON SUNDAY NIGHT AND MONDAY.

 LEFT WITH IFR-MVFR CEILINGS WITH A OCCASIONAL SPRINKLES OR DRIZZLE.            
 ALL OF THE NUMERICAL GUIDANCE SHOWS THE BOUNDARY LAYER MOISTURE                
 DECREASING FROM NORTHWEST TO SOUTHEAST LATE THIS AFTERNOON AND EARLY           
 EVENING...WITH CEILINGS RISING TO THE VFR CATEGORY. THIS SEEMS                 
 REASONABLE BASED ON UPSTREAM OBSERVATIONS. A SOLID DECK OF AC                  
 (10-15K FT) IS FORECAST TONIGHT AND WEDNESDAY. THE VISIBILITY WILL             
 BE P6SM DUE TO THE DRIER AIR AND GOOD MIXING FROM NORTHERLY WINDS OF           
 10 KT.

 COLD FRONT WILL EXIT TO THE SOUTH AND EAST OF THE COASTAL WATERS               
 THIS EVENING. NORTHERLY WINDS AND SEAS WILL INCREASE TO ADVISORY               
 CRITERIA FOR ALL LEGS THIS EVENING. WINDS WILL COME AROUND TO THE              
 NORTHEAST ON WEDNESDAY WITH ADVISORY LEVEL WINDS AND SEAS CONTINUING           
 ACROSS THE OFFSHORE LEGS THROUGH MUCH OF THE DAY. SCATTERED LIGHT              
 SHOWERS WILL ALSO BE SEEN ACROSS THE FORECAST WATERS BEHIND THE                
 FRONT. LOW PRESSURE IS EXPECTED TO DEVELOP WEDNESDAY NIGHT AND                 
 THURSDAY OFF THE SOUTHEAST COAST BUT SHOULD HAVE LITTLE IMPACT ON              
 THE FORECAST WATERS OTHER THAN BACKING WINDS AROUND TO THE NORTH               
 ONCE AGAIN. HIGH PRESSURE WILL THEN REMAIN CENTERED WELL OFF TO

 WILL BE MAKING MINOR UPDATES TO THE FORECAST TODAY. SCATTERED LIGHT            
 SNOW SHOWERS AND FLURRIES EAST OF PEORIA AND SPRINGFIELD SHOULD                
 CONTINUE TO DIMINISH EARLY THIS AFTERNOON LEAVING JUST LAKE EFFECT             
 SNOW BANDS OVER SOUTHERN LAKE MI INTO NW INDIANA. STRATCO CLOUDS               
 THAT WERE CLEARING NORTH AND WEST OF LINCOLN...APPEARS TO BE FILLING           
 BACK IN A BIT LIKE AT PEORIA. CURULE SHOWS BROKEN LOW CLOUDS TO                
 LINGER OVER EASTERN AND NE IL MUCH OF THIS AFTERNOON KEEPING IT                
 MOSTLY CLOUDY. WESTERN IL TO ENJOY MOSTLY SUNNY SKIES. BUT IT WILL             
 BE COLD WITH NW FLOW OFF SNOW FIELD OVER IOWA AND NW IL WITH 1 INCH            
 OF SNOW ON GROUND FROM IL RIVER NW...DUSTING OVER REST OF CENTRAL/SE           
 IL. HIGHS TO RANGE FROM 15 TO 20F FROM I-55 WEST TO THE MID 20S OVER           
 SE IL. AFTER 37 CONSECUTIVE DAYS OF ABOVE NORMAL TEMPS AT PEORIA...            
 SPRINGFIELD AND LINCOLN FROM DEC 10 TO JAN 15...TODAY THE ABOVE                
 NORMAL TEMPERATURE STRETCH SHOULD BE BROKEN WITH BELOW NORMAL TEMPS

 SURFACE MAP AT 16Z SHOWS STRONG 1042 MB ARCTIC HIGH PRESSURE OVER              
 THE CENTRAL PLAINS OVER EASTERN KS/NE NEAR THE WESTERN IA/MO BORDERS.          
 ALOFT AN UPPER LEVEL TROF WAS OVER THE GREAT LAKES INTO IL WITH A              
 WEAK SHORT WAVE GENERATING THE LIGHT SHOW SHOWERS/FLURRIES OVER                
 PARTS OF CENTRAL IL THIS MORNING. THIS UPPER LEVEL TROF AXIS SHIFTS            
 SE OF CENTRAL IL LATER TODAY TAKING THE LIGHT SHOW SHOWERS AND                 
 FLURRIES WILL IT. LOW CLOUDS WILL ALSO DECREASE OVER CENTRAL IL AND            
 OVER EASTERN IL LATE TODAY/EARLY EVENING AS ARCTIC HIGH PRESURE                
 MOVES EAST INTO IA/MO ALLOWING NW WIND 10 TO 15 MPH TO DIMINISH                
 LIGHT BY EVENING. ARCTIC HIGH PRESSURE MOVING OVER IL LATE TONIGHT             
 WILL BRING THE COLDEST NIGHT SINCE DEC 8 WITH LOWS IN THE SINGLE               
 DIGITS OVER PARTS OF CENTRAL IL. WOULD BE EVEN COLDER IF WE HAD A              
 DEEPER SNOW COVER.

 MAIN CONCERNS IN THE SHORT TERM WILL BE CLOUD COVER THROUGH TODAY...           
 AND TEMPERATURES TONIGHT AS SOME OF THE COLDEST AIR SINCE EARLY                
 DECEMBER MOVES INTO THE REGION.                                                
 SHORT TERM...TODAY THROUGH FRIDAY...                                           
 WEAK PVA AHEAD OF UPPER LEVEL TROUGH OVER IOWA HAS PROVIDED JUST               
 ENOUGH WEAK LIFT IN A RATHER SHALLOW MOIST LAYER TO KEEP FLURRIES              
 GOING OVERNIGHT ACROSS MUCH OF THE AREA.  FLURRIES OR LIGHT SNOW               
 SHOWERS WILL CONTINUE TO BE A THREAT THIS MORNING UNTIL H5 TROUGH              
 AXIS CLEARS THE AREA.  OBSERVATIONS SHOW VISIBILITIES ARE GENERALLY            
 7-10 MILES OR GREATER ACROSS THE AREA... SO ANY ACCUMULATION WILL BE           
 VERY LIGHT FROM HERE ON OUT.  THE VERY FINE AND DRY SNOW HAS BLOWN             
 ABOUT QUITE A BIT OVERNIGHT... AND ROAD TRAFFIC HAS INDUCED                    
 MELTING/REFREEZING IN SOME LOCATIONS... SO DRIVERS SHOULD BE AWARE             
 OF SLICK SPOTS.                                                                
 CLEARING LINE OF THE LOW CLOUDS IS ROUGHLY CO-LOCATED WITH THE MID             
 LEVEL TROUGH AXIS... AND IT HAS BEEN VERY SLOW MOVING... STALLED OUT           
 JUST WEST OF THE CWA ALL NIGHT.  NAM/RUC CROSS SECTIONS AND LAYER              
 RH/WIND PLOTS SUGGEST KEEPING THE LOW CLOUDS ACROSS MUCH OF THE CWA            
 THROUGH NOON TIME... WITH GRADUAL CLEARING WEST OF I-55 EARLY IN THE           
 AFTERNOON... WITH CLOUDS LINGERING UNTIL EARLY EVENING IN FAR                  
 EASTERN ILLINOIS.  SO WHILE IT IS TEMPTING TO GO WITH A MORE                   
 OPTIMISTIC SKY FORECAST WITH THE CLEARING LINE SO CLOSE... WILL KEEP           
 THINGS PESSIMISTIC.  SATELLITE OBS OVER MISSOURI ACTUALLY SUGGEST              
 THE CLOUDS ARE REDEVELOPING IN BANDS PARALLEL WITH THE LOW LEVEL               
 FLOW... THESE BANDS EVEN SHOW UP WELL IN 88D DATA FROM KLSX.                   
 CLEARING WILL COME IN OVERNIGHT... BRINGING SOME OF THE COLDEST                
 WEATHER WE HAVE SEEN SINCE EARLY DECEMBER... AND CLEARLY THE COLDEST           
 OF THE YEAR SO FAR.  RECENT TRACES AND MINOR ACCUMULATIONS OF DRY              
 SNOW ARE NOT EXPECTED TO HAVE MUCH IMPACT ON LOW TEMPS TONIGHT.                
 WINDS WILL BE LIGHTEST WEST OF I-55 WHERE THE SFC RIDGE AXIS WILL              
 SET UP.  UPSTREAM TEMPERATURES THIS MORNING OVER EASTERN IOWA HAVE             
 BEEN MORE INFLUENCED BY THE LIGHT SNOW PACK IN THOSE REGIONS... AND            
 THUS DO NOT EXPECT OUR TEMPERATURES TONIGHT TO BE QUITE SO LOW.                
 EXPECT A SLOW WARMING TREND WED-THU AS HIGH PRESSURE SETTLES OFF TO            
 OUR EAST.  HAVE DECREASED MAX TEMPS ON WEDNESDAY AS HIGH PRESSURE              
 REMAINS MORE OR LESS OVERHEAD THROUGH THE AFTERNOON... WITH SFC                
 WINDS NOT REALLY SHIFTING UNTIL EVENING.  ANY WAA JUST ALOFT WILL              
 LIKELY HAVE A HARD TIME MIXING DOWN TO THE SFC WITH STRONG                     
 SUBSIDENCE INVERSION IN PLACE.                                                 
 A WEAK CLIPPER SYSTEM WILL APPROACH FRIDAY INTO FRIDAY NIGHT... AND            
 WHILE SOME SCATTERED FLURRIES CANNOT BE COMPLETELY RULED OUT...                
 CHANCES ARE STILL TOO LOW TO MENTION IN THE FORECAST THIS FAR OUT.             
 THE GFS IS NOW IN AGREEMENT WITH THE ECMWF IN DEFLECTING THE SECOND            
 ARCTIC INTRUSION BEHIND THE CLIPPER WELL TO OUR EAST... BUT TEMPS              
 WILL DIP AGAIN BY THE WEEKEND... WITH SOME REMAINING CLOUD COVER AND           
 A COOL NORTHWEST WIND.  HOWEVER... TEMPERATURES WILL BE ONLY A                 
 LITTLE BELOW NORMAL IN THIS TIME FRAME.                                        
 LONG TERM...SATURDAY THROUGH MONDAY...                                         
 LONGER RANGE SOLUTIONS SUGGEST WE WILL REMAIN IN THIS COOLER/NEAR              
 NORMAL PATTERN EVEN OUT THROUGH DAY 10... AS H5 LOW REMAINS ANCHORED           
 OFF BAFFIN ISLAND... WITH THE MEAN LONGWAVE TROUGH POSITION ACROSS             
 THE NORTHEASTERN CONUS.                                                        
 THE +72 HR AND +240 HR ECMWF H5 PLOTS... VALID THIS AND NEXT                   
 THURSDAY NIGHT... LOOK ALMOST IDENTICAL.                                       
 NEXT CHANCE FOR PRECIP WILL COME TOWARDS SUN/MON AS A CUTOFF LOW               
 CURRENTLY PINCHING OFF OVER THE DESERT SOUTHWEST... EJECTS                     
 EASTWARD.  WITH TEMPERATURES NEAR OR JUST BELOW NORMAL... WINTRY               
 PRECIP MAY BE A THREAT... BUT AT THIS POINT NO MAJOR STORMS APPEAR             
 TO BE ON THE HORIZON.  WILL NEED TO KEEP AN EYE ON EJECTING CUTOFF             
 LOW TO SEE IF IT CAN MANAGE TO PHASE WITH SOME NORTHERN STREAM                 
 ENERGY WHICH MAY BE MORE CONDUCIVE TO SFC CYCLOGENESIS.                        
 BEYOND THAT... WE REMAIN IN THE SAME FAMILIAR PATTERN AS THIS                  
 WEEK... WITH PERIODIC INTRUSIONS OF COLD AIR MAINLY SCRAPING BY TO             
 OUR EAST.  THE GFS IN THE LONGER TERM IS QUITE A BIT COLDER FOR US             
 THAN THE ECMWF AS IT BRINGS DOWN THE ARCTIC AIR ACROSS THE MIDWEST             
 INSTEAD OF THE EAST COAST... BUT THE GFS EARLIER PREDICTED THE SAME            
 THING FOR THIS WEEK... AND ONLY IS JUST NOW CATCHING UP WITH THE               
 ECMWF.

 FOCUS REMAINS ON LAKE EFFECT SNOW BAND. BAND AXIS HAS SHIFTED WEST             
 OF KSBN THOUGH SOME DEBRIS CLOUD FROM THIS WILL CONTINUE TO IMPACT             
 KSBN THRU AFTN. AS WINDS BECOME MORE NW AND WEST DURING FCST PERIOD            
 EXPECT BAND TO PUSH BACK EAST BUT WITH FETCH SHORTENING IN THIS                
 SCENARIO AND FLOW BECOMING MORE ANTICYCLONIC...DOUBT ANY SNOW WOULD            
 OCCUR WITH THIS. SO WL CONT WITH MULTI LEVELS OF CLOUDS AS CURRENTLY           
 OBSVD THRU 09Z AND SCATTER THIS AS FLOW GOES SW.                               
 AT KFWA...DRIER AIR HAS WORKED IN THERE FROM MICHIGAN. SLIGHTLY                
 CYCLONIC CURVATURE AIDING IN FEW TO SCT CU DEVELOPMENT IN VCNTY BUT            
 THIS WILL DISSIPATE BY DARK.  LAKE EFFECT BAND MAY DRIFT BACK TO               
 KFWA DURING EVENING HOURS AS FLOW BECOMES MORE WEST THEN SW. AT THIS           
 TIME HAVE ONLY CARRIED THIS AS REMNANTS OF HIGHER PORTIONS OF THESE            
 BANDS WITH SCT080 EXPECTED.

 TODAY AND TONIGHT...                                                           
 ...SIGNIFICANT LAKE EFFECT SNOW ONGOING...                                     
 AS EXPECTED...TYPE I LAKE EFFECT SNOW BAND HAS SET UP DOWN THE LONG            
 AXIS OF LAKE MICHIGAN. AT 08Z...GOES 3.9-11 MICRON SHOWS IMPRESSIVE            
 BAND THAT HAS UPSTREAM CONNECTION TO LAKE SUPERIOR. THIS                       
 PRECONDITIONING SHOULD HELP OVERCOME SLIGHTLY DRIER AIR WORKING                
 ACROSS WISCONSIN EARLY THIS MORNING. NAM-WRF 925MB PLUME ANALYSIS              
 HAS HAD A GOOD HANDLE ON THE SITUATION AND ALONG WITH FSL RUC13 HAVE           
 BEEN USED FOR MOST OF THIS FORECAST PACKAGE.                                   
 OVERALL...CURRENT FORECAST IS IN GOOD SHAPE. QUESTIONS REMAIN WITH             
 HOW FAR EAST THE MEANDERING BAND WILL MOVE AND HOW MUCH SNOW FAR               
 NORTHEAST LAPORTE COUNTY WILL RECEIVE. NAM-WRF 925MB OMEGA FIELDS              
 SUGGEST THIS BAND WILL BECOME NEARLY STATIONARY FROM BRIDGMAN TO               
 SOUTH BEND AND INTO NORTHERN MARSHALL COUNTY. FROM THERE...SOUTHERN            
 END LOOKS TO MOVE ABOUT ACROSS KOSCIUSKO AND SOUTHERN MARSHALL                 
 COUNTIES. SO FAR...THIS HAS BEEN PLAYING OUT WELL WITH 08Z RADAR               
 RETURNS SHOWING HEAVIEST SNOW ALONG THE BRIDGMAN TO SBN LINE. HAVE             
 BEEN DECENT RETURNS ACROSS NORTHEAST LAPORTE COUNTY WITH REPORTS OF            
 2 INCHES AROUND 07Z IN ROLLING PRAIRIE. SO FAR...THE MODELS WESTWARD           
 BIAS APPEARS TO BE RATHER SMALL...MAYBE ONLY 5 TO 10 MILES. BANDS              
 ARE FINALLY MAKING THEIR WAY INTO SOUTHWEST CASS AND EXTREME                   
 NORTHWEST ELKHART COUNTY. AT THIS TIME...IT DOES LOOK LIKE THE MAIN            
 BAND WILL BE SLIGHTLY EAST OF STRONGEST OMEGA DEPICTION ON                     
 NAM-WRF...JUST GETTING IT INTO WESTERN PORTIONS OF THESE COUNTIES.             
 RADAR RETURNS FROM KLOT AND TMDW SUGGEST A SECOND NARROW BAND WILL             
 PERSIST JUST TO THE WEST OF MAIN BAND. THIS WILL AFFECT MAINLY FAR             
 SOUTHERN BERRIEN AND NORTHERN LAPORTE COUNTIES. CONCERNED THAT FAR             
 NORTH AND NORTHEAST LAPORTE COUNTY WILL EXCEED 6 INCHES THIS                   
 MORNING. CONTEMPLATING ADDING TO THE WARNING. REMAINDER OF WARNING             
 AND ADVISORY AREA EXPECTED TO STAY THE SAME. WILL BREAK OUT CASS AND           
 ELKHART COUNTIES TO ENHANCE WORDING FOR WESTERN PORTIONS.                      
 MOISTURE BEGINS TO WANE DURING THE DAY AS 1040MB HIGH IN THE PLAINS            
 NUDGES EAST. LIKE THE NAM-WRF DEPICTION OF LAKE AGGREGATE TROUGH               
 REMAINING OVER LAKE MICHIGAN THIS EVENING AND WEST TO SOUTHWEST FLOW           
 COUPLED WITH DELTA T VALUES IN THE UPPER TEENS TO KEEP STRATUS AND             
 SOME LIGHT SNOW SHOWERS OR FLURRIES AROUND. DID TRIM POPS BACK AWAY            
 FROM THE LAKE BASED ON 925MB FORECAST OF TRAJECTORIES AND RH FIELDS.           
 CONTINUED TO CUT MOS TEMPS AWAY FROM LAKE WHERE SKIES WILL CLEAR               
 TONIGHT. SHOULD SEE AREAS DIP WELL INTO TEENS AND POSSIBLY SOME                
 SINGLE DIGITS IF SKIES CLEAR EARLY IN THE SOUTHWEST.                           
 &&

 WEDNESDAY THROUGH MONDAY...OVERALL...ONGOING GRIDS/ZFP APPEAR ON               
 TRACK...SO DID NOT MAKE ANY SIGNIFICANT CHANGES THIS PERIOD. AS HAS            
 BEEN THE CASE FOR MOST OF THIS WINTER SO FAR...THE LONGWAVE TROF               
 WILL NOT BE ABLE TO BECOME ESTABLISHED OVER THE MIDWEST IN THE                 
 CURRENT HIGHLY PROGRESSIVE PATTERN. IN THE BEGINNING OF THIS                   
 PERIOD...WARM AIR ADVECTION INCREASES RAPIDLY WEDNESDAY AS THE                 
 SURFACE HIGH MOVES EAST OF THE AREA. TEMPERATURES SHOULD RECOVER TO            
 NEAR NORMAL WEDNESDAY AND THURSDAY. UNLIKE THE LAST SYSTEM...NOT               
 MUCH MOISTURE WILL BE ABLE TO ADVECT INTO THE AREA...SO JUST KEPT              
 LAKE EFFECT SNOW SHOWERS FRIDAY THROUGH SATURDAY IN THE COLDER AIR.            
 THE GFS HAS ALREADY BEGUN TO RETREAT WITH THE VERY COLD AIR                    
 SATURDAY...WHICH IS REFLECTED IN THE MEX MOS HIGHS AT OR ABOVE                 
 FREEZING AT FWA FROM FRIDAY THROUGH MONDAY. THE ECMWF IS VERY                  
 PROGRESSIVE WITH THE SHORT WAVE INDICATING NOT MUCH OF A CHANCE FOR            
 TEMPERATURES TO STAY BELOW NORMAL OVER THE WEEKEND.

 .DISCUSSION...FORECAST PROBLEM WILL BE TEMPERATURES. SATELLITE                 
 SHOWING THAT FLOW HAS BECOME MORE AMPLIFIED OVER THE LAST 24 HOURS...          
 ESPECIALLY FROM THE CENTRAL PACIFIC INTO WESTERN NORTH AMERICA. LARGE          
 AND COLD UPPER SYSTEM NEAR THE DATELINE HAS PUMPED UP THE RIDGE                
 BEHIND SYSTEM NOW DIGGING INTO THE WEST COAST. NORTHERN PORTION OF             
 THIS TROUGH OVER WESTERN CANADA IS MOVING SOUTHEAST. WEAK UPPER OVER           
 SOUTHERN ARIZONA IS ABOUT TO START MOVING NORTHEAST.                           
 AT JET LEVEL...MODELS LOOKED LIKE THEY INITIALIZED REASONABLY WELL.            
 HOWEVER...THEY MAY BE A LITTLE LOW ON SPEEDS ON THE JET SEGMENT                
 BEHIND SYSTEM DIGGING ONTO THE COAST. AT MID LEVELS...MODELS                   
 INITALIZED OKAY. HOWEVER...THEY MAY NOT BE STRONG WITH THE NORTHERN            
 PORTION OF THE TROUGH MOVING INTO THE PACIFIC NORTHWEST. ALSO                  
 MODELS ARE UNDERDOING STRENGTH OF WESTERN RIDGE. NAM/WRF IS DOING              
 THE BEST.                                                                      
 AT LOW LEVELS...NAM WAS DOING THE BEST OF THE BUNCH WITH SURFACE               
 WINDS/PRESSURES. IT HAD THE EXITING RIDGE THE STRONGEST AND                    
 FURTHWEST WEST WITH THE HIGHER PRESSURES. ALSO NAM WAS DOING BETTER            
 WITH THE DEVELOPING LEE TROUGH. THE RUC13 LOOKED CLOSE TO THE NAM.             
 SAME PROBLEM YESTERDAY WITH LOW LEVEL TEMPERATURES BUT NOT AS BAD.             
 MODELS DO NOT HAVE COLD POOL FAR ENOUGH SOUTH AND WEST. THE UKMET              
 WAS DOING SLIGHTLY BETTER THAN THE GFS.                                        
 WILL BE DOING A BLEND OF THE MODELS. BELIEVE THE NAM/UKMET MAY BE              
 DOING BETTER INITIALLY AT MID AND UPPER LEVELS. THEY HAVE THE                  
 NORTHERN STREAM FASTEST AND PRETTY STRONG. WILL THEN BE TRENDING               
 TOWARD THE ECMWF IN THE MIDDLE OF THE PERIOD.                                  
 TONIGHT/WEDNESDAY...SYSTEM OVER THE DESERT TO MOVE ACROSS DURING               
 THIS PERIOD. IT WILL BE WEAK AND HAVE LITTLE MOISTURE WITH IT.                 
 HAVE WARMED UP INTO THE MIDDLE 20S MOST LOCATIONS. WILL STICK CLOSE            
 TO NUMERICAL GUIDANCE FOR TONIGHT. BELIEVE WINDS WILL STAY UP                  
 ENOUGH TO KEEP TEMPERATURES FROM PLUMMETING. MAV DID DO TOO BAD                
 TONIGHT. TEMPERATURE FALL WILL BE IN THE EVENING BEFORE WARM AIR               
 ADVECTION KICKS. SOME CLOUDS AROUND TOMORROW BUT WILL NOT BE THICK.            
 AGAIN WARM ADVECTION WILL BE OVER SNOW PACK WILL TREND TO NEAR OR              
 SLIGHTLY COOLER THAN GUIDANCE. NAM 2 METER FROM YESTERDAY WAS A                
 SLIGHTLY COLD FOR TODAY BUT CLOSEST.                                           
 WEDNESDAY NIGHT/THURSDAY...SYSTEM THAT WILL HAVE A LITTLE MORE IMPACT          
 ON OUR WEATHER WILL BE SYSTEM OVER WESTERN CANADA. AS THIS SYSTEM              
 DIVES SOUTHEAST...IT WILL PUSH A REINFORCING OF COLD AIR INTO THE              
 AREA. FRONTAL PASSAGE LOOKS TO BE LATE IN THE NIGHT OR EARLY IN THE            
 DAY PERIOD. BECAUSE OF THE COLD ADVECTION OVER SNOWPACK AND SOME               
 CLOUDS...WILL GO CLOSER TO THE COOLER GUIDANCE.                                
 THURSDAY NIGHT/FRIDAY...SURFACE RIDGE WILL BE OVER THE AREA OR JUST            
 PULLING AWAY DURING THIS PERIOD. WILL BE UNDER WEAK RIDGE OR                   
 NORTHWEST FLOW ALOFT. BECAUSE ALL THIS...WILL NOT BE TOO AGGRESSIVE            
 IN WARMING THINGS...AND WILL GO WITH PREVIOUS TRENDS.                          
 SATURDAY THROUGH TUESDAY...STILL SOME VARIABILITY IN MODEL SOLUTIONS           
 BUT THEY ARE GETTING CLOSER. DIFFERENCES EXIST ON WHERE THEY CUT               
 OFF NEW LOW...AND WHERE/HOW FAST AND HOW STRONG THEY KICK THIS                 
 SYSTEM. UKMET AND CANADIAN LOOK TO CUT IT OFF FURTHER SOUTHWEST.               
 CANADIAN IS FURTHER SOUTHWEST AND SLOWER THAN ANY OF THE MODELS                
 THROUGH TIME. EVENTUALLY THE ECMWF KICKS OUT THE SYSTEM FASTER...              
 FURTHER NORTH...AND WEAKER. IT HAS BEEN THE MOST CONSISTENT THE                
 LAST COUPLE OF DAYS.                                                           
 THE NEWEST GFS IS MORE CUT OFF...SLOWER...AND FURTHER SOUTH THAN THE           
 PREVIOUS COUPLE OF RUNS. LIKE HPCS ASSESSMENT OF THE SITUATION...AND           
 AGREE THAT THE ECMWF IS THE WAY TO GO AT THIS TIME. BELIEVE SYSTEM             
 COULD DIVE PRETTY FAR SOUTH BASED ON THE STRONG RIDGING BEHIND IT.             
 ALSO LIKE THE FASTER KICKING OUT SYSTEM BASED ON JET POSITION AND              
 FORECAST. SO ENDED UP ADDING A SLIGHT CHANCE OF LIGHT SNOW ON                  
 SATURDAY NIGHT. THINGS MAY GET STARTED LATE IN THE AFTERNOON BUT               
 FEEL IT WILL BE SPRINKLES AT THIS TIME. IF ECMWF TIMING IS RIGHT...            
 PRECIPITATION WILL BE DONE BY 12Z SUNDAY. HOWEVER...IF GFS TIMING IS           
 RIGHT...PRECIPITATION MAY NEED TO BE PULLED INTO SUNDAY. LEFT                  
 HIGH SILENT POPS IN FOR SUNDAY.                                                
 SO SATURDAY WILL BE COOL WITH CLOUDS. COLD AIR GETS PULLED IN BEHIND           
 SYSTEM ON SUNDAY...AND LIKE THE COOLER GUIDANCE BOTH DAYS. SUNDAY              
 LOOKS TO BE DRY. NORTHERN STREAM SYSTEM DIGS INTO WESTERN AND                  
 NORTHERN PORTIONS OF THE COUNTRY ON MONDAY AND TUESDAY. BETTER LIFT            
 LOOKS TO BE OFF TO THE WEST SO KEPT THE FORECAST DRY. HOWEVER...COLD           
 AIR DEFINITELY GETS PULLED BACK...AND THE COLDER HPC TEMPERATURES              
 LOOK GOOD. OTHER THAN KEEPING MONDAY DRY...MADE LITTLE IF ANY CHANGES          
 TO HPC GUIDANCE.

 QUICKLY PLUMMET OVER FRESH SNOW PACK. LINGERING LAKE EFFECT CLOUDS             
 ARE ALREADY SHOWING SIGNS OF DEPARTING THE INTERIOR SW FCST AREA AND           
 UPSTREAM MID CLOUDS ARE STILL MANY HRS AWAY (SIMPLE EXTRAPOLATION              
 PUTS CLOUDS INTO KIWD VCNTY AROUND 04Z). WITH WINDS TO DECOUPLE FOR            
 A TIME WITH SFC RIDGE OVER THE AREA...TEMPS SHOULD NOSE DIVE WITH              
 MANY AREAS SEEING SUBZERO READINGS OVER THE INTERIOR W AND CNTRL.              
 SHOULD FINALLY SEE FIRST SUBZERO READING OF THE WINTER HERE AT THE             
 OFFICE TONIGHT. AT THE LOW END...HAVE GONE CLOSE TO GFS COOP MOS               
 WHICH TAKES TEMPS DOWN TO -8C AT CHAMPION. THAT SHOULD BE A COMMON             
 READING FOR THE TYPICAL INTERIOR COLD SPOTS IN THE INTERIOR W HALF             
 OF FCST AREA. COUNTING ON RETURN FLOW ON BACKSIDE OF SFC RIDGE AND             
 INCREASING CLOUDS LATE EVENING/OVERNIGHT TO KEEP TEMPS FROM FALLING            
 MORE...BUT WILL NEED TO KEEP AN EYE ON TRENDS THIS EVENING. AS FOR             
 LES...WILL CANCEL ADVY FOR ALGER/LUCE/NRN SCHOOLCRAFT WITH FCST                
 ISSUANCE. ADDITIONAL ACCUMULATIONS WILL BE 1 INCH OR LESS BEFORE               
 WINDS BACK OFFSHORE...ENDING LINGERING LES AROUND MIDNIGHT.                    
 FAIRLY STRONG ISENTROPIC ASCENT/WAA PATTERN WILL DEVELOP OVER THE              
 AREA LATE TONIGHT/WED MORNING...BRINGING INCREASING CLOUDS. IT                 
 APPEARS BEST POTENTIAL OF MOISTENING THE LOW LEVELS TO ALLOW SNOW TO           
 REACH THE SFC WILL OCCUR JUST N OF UPPER MI. HAVE THUS PAINTED SNOW            
 CHANCES ONLY ACROSS THE N HALF OF LAKE SUPERIOR LATE TONIGHT/WED.              
 GIVEN STRENGTH OF ASCENT...WOULDN`T BE SURPRISED IF A FEW FLURRIES             
 BRUSH THE KEWEENAW OR ALGER/LUCE COUNTIES. COOLER GFS MOS GUIDANCE             
 LOOKED REASONABLE FOR HIGHS WED SINCE THERE SHOULD BE SOME DELAY               
 WARMING THE NEAR SFC LAYER AFTER RECENT CHILL.                                 
 THU/FRI...ATTENTION TURNS TO TROF WHICH AMPLIFIES OVER THE PLAINS              
 AND THEN MOVES ACROSS THE GREAT LAKES. SEVERAL SHORTWAVES WILL BE              
 EMBEDDED WITHIN THE TROF WITH FIRST LIFTING NE INTO THE UPPER LAKES            
 THU AFTN. AIRMASS IS INITIALLY DRY...SO NOT EXPECTING MUCH IN THE              
 WAY OF -SN COVERAGE WITH IT. HAVE THUS DELAYED CHC POPS FROM                   
 INHERITED FCST...LEAVING THE E DRY THRU THU MORNING. MORE IMPORTANT            
 SYSTEM CROSSES THE AREA THU NIGHT WITH SHARP WIND SHIFT AND STRONG             
 CAA IN ITS WAKE. LOOKS LIKE A GOOD SETUP FOR A PERIOD OF LAKE                  
 ENHANCEMENT (850MB TEMPS ARE ALREADY LOW ENOUGH FOR JUST PURE LES              
 AT THE TIME OF TROF PASSAGE/SYNOPTIC FORCING). EXAMINATION OF GFS              
 FCST SOUNDINGS SUPPORTS POTENTIAL FOR A PERIOD OF MDT/HVY SNOW WITH            
 DEEP MOISTURE THRU AT LEAST 15KFT AND UPWARD MOTION INTERSECTING               
 DECENT DEPTH OF FAVORABLE DENDRITIC SNOW GROWTH TEMPS. ALTHOUGH                
 SNOWBELTS FAVORED UNDER NW WINDS WILL SEE HEAVIEST SNOW...WINDS                
 SOMETIMES VEER MORE SHARPLY TO THE N IN THESE TYPE OF EVENTS. SO               
 THERE MAY BE A BRIEF PERIOD OF MDT/HVY SNOW FOR N WIND FAVORED                 
 LOCATIONS AS WELL THU NIGHT. ANOTHER SHORTWAVE DROPPING SE ACROSS              
 THE AREA FRI AFTN SHOULD GIVE A BOOST TO LES AGAIN. AT THIS                    
 POINT...IT APPEARS THIS WILL BE A SOLID ADVY TYPE EVENT FOR LAKE               
 SUPERIOR COUNTIES AND POTENTIALLY A WARNING EVENT FOR A FEW                    
 LOCATIONS.

 ANOTHER TROF BECOMING ESTABLISHED LATE IN THE WEEKEND AND EARLY NEXT           
 WEEK OVER THE GREAT LAKES/MISSISSIPPI VALLEY AS RIDGE AMPLIFIES                
 ALONG THE W COAST. SO THIS SHOULD GENERALLY BE A SNOWY PERIOD...               
 ESPECIALLY NEAR LAKE SUPERIOR. THERE ARE SOME ISSUES ON TIMING AND             
 DETAILS OF THE TROF TAKING SHAPE OVER THE REGION LATE IN THE                   
 WEEKEND. 00Z ECMWF DROPS A PAIR OF SHORTWAVES SE WITH THE FIRST                
 LEADING TO A SFC LOW OVER LAKE SUPERIOR/UPPER MI SUN EVENING. THIS             
 IS FOLLOWED BY ANOTHER SHORTWAVE MON WHICH INTRODUCES A SHOT OF                
 ARCTIC AIR. THIS WOULD BE FAVORABLE FOR SIGNIFICANT SNOW FOR THE               
 ENTIRE FCST AREA NEAR LAKE SUPERIOR. 00Z GFS WAS SIMILAR TO THE                
 ECMWF...BUT GENERALLY 12HRS SLOWER. 00Z UKMET WAS ALSO SUPPORTIVE              
 FOR THE PATTERN OVER GREAT LAKES AREA...BUT UPSTREAM RIDGE ALONG THE           
 W COAST IS MUCH FLATTER BY 00Z MON...SUGGESTING LESS AMPLIFIED                 
 TROFFING HERE EARLY NEXT WEEK. 00Z CANADIAN GLOBAL WAS ALSO                    
 SUPPORTIVE OF THE OVERALL PATTERN...BUT WAS WEAKER WITH FIRST                  
 SHORTWAVE. FOR NOW...WILL LEAN TOWARD THE GFS/ECMWF FOR DETAILS                
 (PAIR OF SHORTWAVES DROPPING THRU THE AREA). TIMING WILL REMAIN                
 UNCERTAIN UNTIL EVENT NEARS...AND HAVE THUS UTILIZED HPC GUIDANCE              
 FOR NOW. PATTERN DOES FAVOR A SFC LOW OR SHARP TROF DROPPING ACROSS            
 LAKE SUPERIOR WITH FIRST SHORTWAVE. THIS WOULD PROVIDE A DECENT                
 PERIOD OF LES/LAKE ENHANCED SNOW FOR NW/N WIND FAVORED LOCATIONS.              
 SECOND SHORTWAVE WILL REENERGIZE LES/LAKE ENHANCED SNOW...ESPECIALLY           
 FOR NW WIND FAVORED LOCATIONS. NEAR NORMAL HIGH TEMPS SAT/SUN SHOULD           
 TREND DOWN MON/TUE.

 TAKING A LOOK AT THE WATER VAPOR IMAGERY THIS MORNING...MUCH OF THE            
 NATION WAS RELATIVELY DRY.  IN GENERAL...ALL BUT THE EASTERN THIRD             
 OF THE NATION WAS UNDER THE INFLUENCE OF HIGH PRESSURE.  THERE WERE            
 THREE SURFACE LOWS OF NOTE THIS MORNING.  THE FIRST WAS THE EXITING            
 LOW PRESSURE SYSTEM...CENTERED OVER JUST OFF THE NEW ENGLAND                   
 COAST...WITH A COLD FRONT STRETCHING THROUGH THE CAROLINAS AND                 
 NORTHWESTERN FLORIDA.  THE SECOND...SLIGHTLY WEAKER LOW WAS SITUATED           
 OVER THE NORTHWEST TERRITORIES UP IN CANADA.  THIS FEATURE HAD A               
 WARM FRONT DROPPING SOUTH THROUGH SASKATCHEWAN AND EASTERN MONTANA.            
 WARMER TEMPERATURES WERE NOTED ACROSS NORTHERN MONTANA.  FOR                   
 EXAMPLE...THE 09Z TEMPERATURE AT CUT BANK MONTANA WAS 28                       
 DEGREES...WHILE CLOSER TO HOME THE TEMPERATURE WAS -16 AT                      
 INTERNATIONAL FALLS.  LOOKING HIGHER UP INTO THE ATMOSPHERE...AND              
 THE WATER VAPOR IMAGERY AND RUC...THE MID LEVEL TROUGH WAS SET UP              
 FROM EASTERN LAKE SUPERIOR THROUGH THE SOUTHERN TIP OF THE UPPER               
 PENINSULA...AND DOWN THROUGH IOWA...ALL THE WAY THROUGH SOUTHERN               
 ARIZONA.                                                                       
 CONTINUE TO BE CONCERNED WITH LAKE EFFECT SNOW ACROSS OUR THE                  
 CENTRAL AND EASTERN LAKE SUPERIOR SHORELINE TODAY.  THE BANDS OF               
 SNOW HAVE BEEN CONTINUING THE SLOWLY SHIFT EASTWARD OVERNIGHT AS               
 WINDS HAVE BECOME MORE NORTHWESTERLY...INCREASING THE CONVERGENCE              
 ACROSS THIS AREA.  WAS ORIGINALLY CONCERNED WITH THE AMOUNT OF DRY             
 AIR THAT WILL COME INTO THIS AREA WITH OF CENTRAL...WESTERN...AND              
 NORTHERN LAKE SUPERIOR CLOUD FREE EARLIER THIS MORNING.  FURTHER TO            
 OUR WEST...DEW POINTS ARE IN THE UPPER TEENS TO MID 20S BELOW ZERO.            
 ACROSS THE CWA DEW POINTS WERE STILL IN THE SINGLE DIGITS ABOVE                
 ZERO.  EVEN WITH THIS DRIER AIR FILTERING IN...THE NNW TO SSE CLOUDS           
 HAVE DEVELOPED FAIRLY NICELY OVER THE PAST SEVERAL HOURS ACROSS THE            
 EASTERN HALF OF THE LAKE.  THE BETTER FETCH FOR LAKE EFFECT WAS ALSO           
 EXPECTED TO OFFSET SOME OF THIS DRY AIR.  EVENING SHIFT DID HOIST              
 ADVISORIES FOR ALGER COUNTY EASTWARD THOUGH THIS EVENING.  3-5KFT              
 INVERSION HEIGHTS...GOOD MOISTURE AROUND THE SNOW GROWTH REGION                
 SHOULD ALLOW FOR ADVISORY CRITERIA THROUGH THIS EVENING.                       
 WARM AIR WILL SURGE EASTWARD INTO THE UPPER PENINSULA DURING THE DAY           
 WEDNESDAY AS THE WARM FRONT OVER NORTHEASTERN MONTANA SWINGS OUR WAY           
 AND THE 500MB RIDGE SLIDES OVERHEAD.  850MB TEMPERATURE SHOULD                 
 RISING TO THE -1 TO -3 RANGE BY 00Z THURSDAY.  WITH THIS SAID...AM             
 HESITANT TO DECREASE CURRENT FORECAST TEMPERATURES ANY...EVEN GIVEN            
 SLIGHTLY COOLER TEMPS FROM THE GFS/MAV WITH MORE CLOUDS                        
 ANTICIPATED.  SO...FEW CHANGES WERE MADE TO TEMPS FOR MID WEEK.

 .SHORT TERM /TONIGHT THROUGH THURSDAY/...                                      
 MAIN FORECAST ISSUE THIS PERIOD IS LAKE EFFECT SNOW TONIGHT WITH               
 SOME MODEL DISAGREEMENT IN REGARD TO THE FLOW FOR THE EVENT. THE               
 NAM DOES NOT SEEM TO HAVE A GOOD HANDLE ON THE SITUATION AND IS                
 HAVING A HARD TIME WITH THE CURRENT BANDS ACROSS CENTRAL NEW YORK,             
 AND TONIGHT THE NAM SOUNDINGS WANT TO TURN THE FLOW MORE WESTERLY              
 TO ABOUT 300 DEGREES. THIS WOULD LIKELY CONSOLIDATE THE MULTI-                 
 BANDS INTO MORE OF A STRONGER SINGLE BAND, ESPECIALLY THIS                     
 EVENING AFTER PASSAGE OF S/W. THE GFS AND RUC AS WELL AS LAMP DATA STAY        
 MORE WITH 320 FLOW AND MULTI-BAND EVENT. LOOKING UPSTEAM, NO SIGNS             
 OF FLOW BACKING MORE WESTERLY SO WE HAVE DECIDED TO STAY WITH THE              
 MULT-BAND SCENERIO WHICH WILL CONTINUE TO AFFECT MUCH OF CENTRAL               
 NEW YORK COUNTIES THRU THE NIGHT. WITH TEMPERATURES DROPPING INTO              
 THE LOWER TEENS, THE SNOW WILL HAVE A LARGE FLUFF FACTOR AND WILL              
 ACCUMULATE QUICKLY WITH PERSISTENT BANDS.                                      
 SOME LIGHTER SNOW SHOWERS AND FLURRIES WILL CONTINUE INTO                      
 WEDNESDAY MORNING AS HIGH PRESSURE BUILDS EASTWARD FROM THE                    
 OHIO VALLEY. AT LEAST SOME FLURRIES MAY CONTINUE THROUGH THE                   
 AFTERNOON AS THE FLOW DOES NOT SHIFT TO THE SW LATE IN THE AFTN OR             
 EVENING AS THE SFC HIGH MOVES TO OUR EAST.                                     
 QUIET DAY ON THURSDAY WITH SFC RIDGE OFF THE NEW ENGLAND COAST AND             
 SWLY FLOW WARMING TEMPS BACK INTO THE 30S.                                     
 FWC TEMPS ARE QUITE A BIT COLDER THAN THE ETA AND GFS THRU THE                 
 PERIOD. TONIGHT THE NGM CLEARS OUT THE FA WHICH IS UNLIKELY ACROSS

 COLD WINTER WEATHER WILL LINGER THOUGH WEDNESDAY WITH TEMPERATURES             
 REMAINING SOME 10 TO 20 DEGREES BELOW SEASONAL VALUES. SNOW                    
 FLURRIES ARE POSSIBLE AT TIMES TONIGHT AND INTO WEDNESDAY MORNING              
 MAINLY EAST OF THE RIO GRANDE. THE BORDERLAND WILL HAVE A SLIGHT               
 REPRIEVE IN THE WEATHER WEDNESDAY AFTERNOON INTO THURSDAY MORNING              
 WITH TEMPERATURES WARMING SOMEWHAT. HOWEVER...ANOTHER WINTER STORM             
 IS FORMING OVER THE PACIFIC NORTHWEST AND IS FORECAST TO MOVE INTO             
 ARIZONA THURSDAY...WHICH WILL ADVECT CONSIDERABLE SUBTROPICAL                  
 MOISTURE FROM THE GULF OF CALIFORNIA INTO THE BORDERLAND...BRINGING            
 SCATTERED RAIN SOWERS LATER THURSDAY INTO FRIDAY MORNING.                      
 FURTHERMORE...ANOTHER VERY COLD POLAR FRONT WILL PUSH SOUTHWARD                
 INTO THE AREA FRIDAY MORNING ADDING TO THE RISK OF A MIXED BAG OF              
 WINTRY PRECIPITATION WHICH COULD INCLUDE FREEZING RAIN AND SLEET               
 BEFORE CHANGING OVER TO SNOW BY FRIDAY EVENING...AND THE SNOW                  
 COULD BE POSSIBLY HEAVY AT TIMES OVER BOTH THE MOUNTAINS AND EVEN              
 IN SOME OF THE LOWLANDS. THIS SYSTEM SHOULD MOVE OUT OF THE                    
 BORDERLAND BY SATURDAY NIGHT.                                                  
 &&                                                                             
 .DISCUSSION...                                                                 
 NOT AS IF ALL THIS WAS UNEXPECTED BUT SLOWLY AND SURELY THE                    
 DETAILS ARE STARTING TO GET INTO SOMEWHAT OF A FOCUS. AS WE WRITE              
 OUR HIGH HAS BEEN 33 DEG F WITH THE RECORD LO MAX TODAY AT 36.                 
 SHORT TERM MESO ETA AND RUC SHOW MINOR VORT DISTURBANCES IN THE                
 SUBTROPICAL JET OVERHEAD (FCST TO PEAK AT 160 KTS OHD                          
 WEDNESDAY) SO SOME SNOW FLURRIES ARE NOT OUT OF THE QUESTION                   
 TONIGHT MAINLY EAST OF THE RIO. THIS SHOULD NOT BE THAT SIGNIFICANT            
 AS ALL WE HAVE IS SATURATED UPSLOPE CLOUDS FROM 850 TO 750 MB AND              
 THEN THE SUBTROPICAL JET CLOUDS 15-20K AGL SO SEEDING SHOULD NOT BE            
 A REAL CONCERN AT THIS TIME. HUDSPETH MAY SEE SOME LIGHT SNOW                  
 BUT BETTING UNDER ANY ADVISORY CRITERION AT THIS TIME. OVERALL                 
 MODELS IN FAIRLY GOOD AGREEMENT GIVING US A SLIGHT REPRIEVE IN OUR             
 `WINTER` WITH SOME WARMING AND PARTLY CLOUDY CONDITIONS WED AFTN-THU           
 MIDDAY. THEN LIFE GETS INTERESTING WITH BOTH NAM AND GFS DIGGING A             
 STRONG UPPER LOW NOW OVER THE PACIFIC NW (-34C H5) INTO ARIZ BY                
 THURSDAY. THE NAM IS A LITTLE SLOWER BY ABOUT 6-12 HOURS AND LESS              
 AGGRESSIVE ON THE QPF. THE LATEST 12Z GFS ACTUALLY STALLS THE LOW IN           
 SOUTH CENTRAL ARIZ THROUGH SATURDAY MORNING `ALMOST` IN A PERFECT              
 POSITION FOR DYNAMICS (ACTUALLY A TAD NORTH BRINING IT INTO THE                
 NORTHERN PORTION OF OUR CWA SATURDAY BUT CLOSE ENOUGH). THIS SHOULD            
 COUPLE WITH ANOTHER BACKDOOR FRONT INTO INTO THE CWA (1045 MB HIGH             
 DRIVER) BETWEEN 12Z AND 18Z FRIDAY. EXPECT AN EXCELLENT SUBTROPICAL            
 BAJA TAP BY THURSDAY PM WITH RAIN EVEN AT THE HIGH ELEVATIONS.                 
 FORECAST SOUNDINGS (BOTH NAM AND GFS) SHOW AN ELEVATED INVERSION               
 AROUND 750 MB WHICH COULD MAKE LIFE INTERESTING AS THE LOWER                   
 ELEVATIONS AIR STARTS TO COOL DOWN ALL DAY FRIDAY THERE MAY BE AN              
 WINDOW FRIDAY MORNING WHERE THERE IS RAIN AROUND 6-8K MSL AND                  
 FREEZING RAIN IN THE VALLEYS. NEVERTHELESS FRIDAY POSES A WINTRY MIX           
 PROBLEM AND I HOPE FOR NOW THE COLUMN OF AIR FROM 850 TO 700 MB                
 COOLS FAST TO AVOID A POTENTIAL FREEZING RAIN/ICE PROBLEM FOR                  
 FRIDAY. HOPEFULLY THIS WINDOW WILL BE SMALL AND WE WILL TRANSITION             
 INTO THE DAY WITH A MIX OF RAIN AND SLEET INTO SNOW AS THE                     
 TEMPERATURE DROPS. AT THE MOMENT WE ARE CALCULATING FROM BOTH MODELS           
 SOME UNBELIEVABLE SNOW AMOUNTS WITH 12-15+ INCHES FOR THE MOUNTAINS            
 AND 6 - 12 INCHES EVEN IN THE LOWLANDS FOR FRIDAY EVENING AND                  
 SATURDAY. HENCE SPS ISSUED FOR HEADS UP. TROPA NOW SCHEDULED FOR 06Z           
 SUNDAY SO CLEARING IT OUT LATE SATURDAY.                                       
 THEN TO MAKE LIFE MORE INTERESTING...THE 12Z GFS HAS ANOTHER SYSTEM            
 DROPPING INTO THE CWA WITH PRECIP FOR NEXT MONDAY AND TUESDAY...NOT
