AS OF 1040 AM EST...WE HAVE MADE MINOR ADJUSTMENTS TO THE GRIDDED               
DATABASE...MAINLY TO INCH MAX TEMPS UPWARD ACROSS THE UPPER HUDSON              
VALLEY...SW VT...AS WELL AS WITHIN THE WESTERN ADIRONDACKS...WHERE              
THINNER CLOUDS SHOULD ALLOW TEMPS TO REACH THE LOWER/MID 60S BY                 
EARLY AFTERNOON. ELSEWHERE...THICKER CLOUDS AND SOME LIGHT                      
SHOWERS/DRIZZLE SHOULD LIMIT MAX TEMPS FROM RISING MORE THAN 2-4                
DEGREES OVER CURRENT TEMPS...MAINLY HOLDING IN THE UPPER 50S ACROSS             
THE SE CATSKILLS...LITCHFIELD HILLS AND PORTIONS OF THE BERKS...TO              
THE LOWER 60S ACROSS PORTIONS OF THE MID HUDSON VALLEY...WARMEST                
CLOSER TO THE CAPITAL REGION.                                                   
AS FOR RAIN...PATCHY LIGHT RAIN/DRIZZLE IS OCCURRING ACROSS E-FACING            
SLOPES OF THE CATSKILLS/HELDERBERGS...AND WITHIN PORTIONS OF THE                
BERKS AND MID HUDSON VALLEY. THE AREAL COVERAGE OF THIS LIGHT                   
RAIN/DRIZZLE SHOULD INCREASE THROUGH EARLY THIS AFTERNOON...WITH                
SOME SHOWERS/SPRINKLES POSSIBLY REACHING THE CAPITAL REGION AROUND              
OR AFTER NOONTIME. SHOWERS WILL ALSO INCREASE FURTHER ACROSS                    
PORTIONS OF THE MID HUDSON VALLEY AND NW CT BY MIDDAY...AS CURRENT              
BAND ACROSS NYC/LI LIFTS NNW. THE RUC13 APPEARS TO BE HANDLING THIS             
BAND RATHER WELL...DEPICTED WITHIN THE 850-700 MOISTURE FLUX                    
CONVERGENCE.

AS LOW MOVES EASTWARD OUT TO SEA AND WEAKENS. SOME LINGERING                    
PRECIPITATION POSSIBLE. UPPER SYSTEM EXPECTED TO FINALLY OPEN ON                
FRIDAY. RIDGING BUILDS IN BRIEFLY BETWEEN THE DEPARTING LOW AND AN              
ADVANCING LOW PRESSURE SYSTEM FRIDAY. WESTERN PORTIONS OF FORECAST              
AREA MAY GET TO SEE SOME SUN FRIDAY AFTERNOON. MAIN LOW ASSOCIATED              
WITH NEXT SYSTEM WILL PASS WELL TO OUR NORTH AND WEST SATURDAY.                 
ITS ASSOCIATED COLD FRONT WILL SWING THROUGH ON SATURDAY. HAVE                  
POPS INCREASING FRIDAY NIGHT ESPECIALLY AFTER MIDNIGHT WITH LIKELY              
FOR SATURDAY AND DECREASING POPS SATURDAY NIGHT. DESPITE THE CLOUD              
COVER AND RAIN SHOWERS SATURDAY HIGHS ARE EXPECTED TO BE ABOVE                  
NORMAL BUT COOLER THAN PREVIOUS DAYS. THE REINFORCING SHOT OF                   
COLDER AIR NOT EXPECTED UNTIL SUNDAY.

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...                                   
A DEEP UPPER LOW IS FORECAST TO SLOWLY LIFT OUT OF THE GREAT LAKES              
REGION SUNDAY AND STALL OVER CENTRAL QUEBEC ON MONDAY. IT WILL BRING            
UNSETTLED WEATHER TO THE REGION FOR SUNDAY AND MUCH OF THE DAY                  
MONDAY...ESPECIALLY NORTH OF ALBANY...BEFORE A WEAK HIGH OVER THE               
NORTHERN PLAINS WEDGES IN MONDAY NIGHT FOR A BRIEF BREAK IN THE                 
WEATHER LATE MONDAY NIGHT AND EARLY TUESDAY. COOLER AIR WILL FLOW               
INTO THE REGION SUNDAY NIGHT WITH 850 HPA TEMPERATURES STEADILY                 
DROPPING SUNDAY NIGHT TO MINUS 3 TO MINUS 7 DEGREES OVER THE                    
REGION...ALONG WITH LOW LEVEL WINDS DOWN THE LENGTH OF LAKE ONTARIO             
BRINGING ADDED MOISTURE TO THE ADIRONDACKS AND THE MOHAWK                       
VALLEY...AND WITH 850 TEMPS MINUS 5 TO MINUS 7 IN THESE AREAS SUNDAY            
NIGHT RAIN SHOWERS WILL MIX AND/OR CHANGE TO SNOW                               
SHOWERS...ESPECIALLY OVER THE HIGHER TERRAIN. THE ONLY DECENT DAY IN            
THE WHOLE EXTENDED PERIOD APPEARS TO BE TUESDAY...AND HIGH CLOUDS               
ASSOCIATED WITH THE NEXT SYSTEM TO AFFECT THE REGION WILL PROBABLY              
SPREAD OVER MOST OF THE REGION SHORTLY AFTER DAYBREAK TUESDAY. AT               
THIS POINT IT LOOKS LIKE THE DAY SHOULD BE CLOUDY...BUT DRY...UNTIL             
EARLY EVENING WHEN OVERRUNNING PRECIPITATION AHEAD OF THE LOW IN THE            
OHIO VALLEY SPREADS INTO THE REGION. WE MAY POSSIBLY HAVE SOME                  
P-TYPE ISSUES TO CONTEND WITH EARLY WEDNESDAY...WITH 850 HPA TEMPS              
RISING TO ABOVE ZERO INTO THE CENTRAL ADIRONDACKS AROUND DAYBREAK               
WEDNESDAY WITH OVERNIGHT LOWS IN THE LOW 20S. AT THIS STAGE IN THE              
GAME WILL SLEW THE MIN TEMPS TO EARLIER IN THE NIGHT WHICH MAY WELL             
END UP BEING THE CASE WITH  TEMPS WARMING UP DURING THE NIGHT AND               
CHANGING SNOW INTO RAIN. IT/S NOT A PLEASANT SCENARIO BY ANY                    
MEANS...WITH HIGHS WEDNESDAY ONLY IN THE LOW 40S...SO IT WILL BE A              
BITING COLD RAIN...AND SHOULD THE RIGHT CONDITIONS MATERIALIZE                  
TUESDAY NIGHT WE COULD END UP WITH SOME PATCHES OF FREEZING RAIN IN             
COLDER VALLEYS. FEEL ITS BEST AT THIS POINT TO ADDRESS THE SITUATION            
OVER THE WEEK END OR EARLY NEXT WEEK AND THINGS WILL LIKELY BE                  
DIFFERENT BY THEN. THE TYPICAL ALBANY WEATHER IN NOVEMBER IS NOT                
EXACTLY CHAMBER OF COMMERCE QUALITY WITH AN AVERAGE HIGH OF 47...LOW            
OF 39 AND A MISERLY 37 PERCENT PERCENT OF THE RELATIVELY FEW HOURS              
OF SUNSHINE THAT ARE EVEN POSSIBLE.

LOW PRESSURE SYSTEM TO THE SOUTH IS BRINGING IN SOME RAIN SHOWERS               
TO KPOU AND KALB. THERE/S A CHANCE FOR SOME SHOWERS TO AFFECT                   
KGFL LATER IN THE AFTERNOON. LOW CLOUDS WILL CONTINUE TO MOVE                   
NORTHWARD WITH MVFR CIGS AT ALL TERMINALS AROUND 00Z.                           
OVERNIGHT...WINDS WILL SUBSIDE AT ALL TERMINALS. KPOU WILL                      
CONTINUE TO EXPERIENCE VCSH/-DZ...AS CIGS DECREASE TO IFR AROUND                
04Z. KGFL WILL EXPERIENCE IFR VSBYS TOWARDS LATE NIGHT INTO EARLY               
MORNING. ALL TERMINAL VSBYS WILL REBOUND AROUND 15Z...WHILE CIGS

REFER TO THE  LATEST FLOOD ADVISORY...ABOUT A BEAVER DAM IN A                   
CULVERT HAS BACKED UP A SUBSTANTIAL AMOUNT OF WATER BEHIND A                    
RAILROAD TRACK IN NORTH GREENFIELD IN SARATOGA COUNTY WHICH POSES A             
FLOOD THREAT SHOULD THE TRACKBED SUDDENLY WASH OUT. CREWS HAVE                  
CLEARED SOME OF THE DEBRIS WHICH IS ALLOWING MORE WATER TO FLOW                 
THROUGH AND GRADUALLY LOWER THE IMPOUNDMENT. THE PROCESS IS LIKELY              
TO TAKE SEVERAL DAYS. OTHERWISE THE PERIOD SHOULD BE RELATIVELY                 
QUIET AS FAR AS THE RIVERS ARE CONCERNED. THE BRUNT OF THE PRECIP               
FROM THE STORM MOVING UP THE COAST WILL BE WELL SOUTH AND EAST OF               
THE FORECAST AREA...WITH ONLY LIGHT AMOUNTS OF PRECIP THROUGH                   
FRIDAY. THE PASSING COLD FRONT SATURDAY AND THE UPPER LOW SUNDAY                
WILL BRING FAIRLY LIGHT AMOUNTS OF PRECIP TO THE REGION...MOST                  
LIKELY AROUND HALF AN INCH. THE STORM MOVING OUT OF THE MISSISSIPPI             
VALLEY STARTING MIDWEEK HAS A POTENTIAL TO BRING MORE OF A SOAKING              
RAIN...OVER A PERIOD OF SEVERAL DAYS. THAT SYSTEM IS FIVE TO SIX                
DAYS OUT...HOWEVER...AND A LOT IS LIKELY TO CHANGE BY THEN.                     
MELTING SNOW IN THE WESTERN ADIRONDACKS HAS INCREASED THE FLOW                  
OF THE MOOSE RIVER FLOWING OUT OF THE FULTON CHAIN AND ALSO                     
THE FLOW OF THE WEST CANADA FLOWING INTO HINCKLEY RESERVOIR.                    
RAIN AND MELTING SNOW IN LATE OCTOBER AND EARLIER THIS MONTH                    
HAS BROUGHT THE LEVEL OF THE SCHOHARIE RESERVOIR UP A LITTLE                    
MORE THAN 25 FEET. THERE WAS ABOUT A FOOT AND A HALF OF WATER                   
FLOWING OVER THE NOTCH. THE WATER LEVEL WILL GRADUALLY DROP                     
OVER THE NEXT FEW DAYS. THE SCHOHARIE CREEK DOWNSTREAM WAS                      
ONLY SLIGHTLY ABOVE NORMAL AND LESS THAN A THIRD BANKFULL.

NE WINDS INCREASE THROUGH THE REMAINDER OF THE DAY WITH APPROACH                
OF COASTAL LOW. SWELL FROM THE STORM HAS HELPED BUILD WAVES TO                  
SLIGHTLY NEAR 7 FEET AT 44025 ALREADY. HAVE MADE MINOR CHANGES TO               
WAVE GRIDS THROUGH THIS EVENING TO ACCOUNT FOR INCREASING SWELL.                
STRONGEST...GUSTIEST WINDS TO ARRIVE LATE AFTERNOON AND THIS

TONIGHT...BUT DON`T THINK IT WILL ADVANCE FARTHER NORTH. THE HARBOR             
WILL BE A CLOSE CALL...BUT THINK IT`LL FALL JUST SHY OF 35 KT. SO               
WILL GO WITH GALE WARNING TONIGHT ON THE OCEAN...AND SCA ELSEWHERE.             
PRESSURE GRADIENT OVER THE WATERS WEAKENS THROUGH THE DAY ON

FLOODING IS NOT A LARGE CONCERN...WITH ONLY SOME URBAN AND POOR

MAINLY WITH TONIGHT`S HIGH TIDE CYCLE. WINDS WON`T BE TOO MUCH OF               
FACTOR WITH THIS AFTERNOON`S CYCLE...SO NO CONCERNS THERE. THURSDAY             
AFTERNOON`S HIGH TIDE CYCLE LIKELY WON`T POSE ANY PROBLEMS EITHER               
AS WINDS ARE FORECAST TO SUBSIDE THROUGH THE DAY...BUT WILL                     
HOWEVER HAVE TO KEEP AN EYE ON TIDAL PILING.                                    
FOR TONIGHT AND THURSDAY AFTERNOON...WOULD NEED DEPARTURES                      
OF AROUND 2 1/2 FT FOR MINOR COASTAL FLOODING DURING TIMES OF HIGH              
TIDE. DEPARTURES OF 3.5-4 FT ARE NEEDED FOR MODERATE.                           
PERHAPS THE BIGGEST THREAT OF ANY FLOODING WILL BE ACROSS THE                   
WESTERN SOUND...WHERE DEPARTURES OF 2 1/2 TO 3 FT WILL BE NEEDED FOR            
MINOR FLOODING DURING TONIGHT`S AND THURSDAY AFTERNOON`S HIGH TIDE

APPEARS TO BE TOO HIGH GIVEN CLOUDS...PRECIPITATION AND COLD                    
TEMPERATURES IN THE LOW LEVELS. KEPT THE HIGHEST PRECIPITATION                  
CHANCES OVER FAR LOWER MICHIGAN WHERE MOISTURE SHOULD BE DEEPER AND             
LIFT BETTER. AN UPPER LEVEL TROF WILL MOVE OVER THE AREA SATURDAY               
NIGHT...SO HAVE KEPT PRECIPITATION CHANCES INTACT. THERE MAY BE SOME            
LAKE ENHANCEMENT TO PRECIPITATION OVER FAR SW LOWER MICH...BUT GIVEN            
250 TO 280 DEGREE PREVAILING LOW LEVEL WINDS...A PREDOMINANT LAKE

WARM TEMPERATURES AGAIN ON THURSDAY CLOSE OUT A WONDERFUL ABOVE                 
NORMAL STRETCH AS TROFING TAKES OVER BEHIND FRONTAL PASSAGE THURSDAY            
EVENING USHERING IN A RETURN TO REALITY.  UPR TROF CLOSING OFF TODAY            
OVER CENTRAL US MOVES EAST WITH ASSOC SFC LOW AND BECOMES NEARLY                
VERTICALLY STACKED BY FRI NIGHT. MODELS GENERALLY IN GOOD AGREEMENT             
THROUGH THE PD AND WITH SFC LOW OCCLUDING AND STACKED SYSTEM SLOWING            
DOWN...FOLLOWED NAM WHICH IS SLOWEST AMONG MODEL GUIDANCE.                      
INSTABILITY WITH FRONT IS CONFINED TO A NARROW BAND ALONG THE BNDRY             
WHICH LEAVES THE CWA WARM AND SUNNY YET AGAIN FOR THURSDAY.  H85                
TEMPS/TRAJECTORIES/FCST SOUNDINGS ALL POINT TO HEAVILY WEIGHTING                
PERSISTENCE FOR SUNNY HIGH TEMPS IN THE LOW 70S ONCE AGAIN.                     
WITH FRONTAL TIMING SLATED FOR THU EVENING EFFECTS BEGIN TO ARRIVE              
IN WESTERN CWA NEAR 00Z. INSTABILITY IS LACKING IN GENERAL AND WHAT             
IS PRESENT IS LOCATED IN A CORRIDOR ALONG THE BNDRY.  H85/H92 WINDS             
AROUND 40KT ACROSS MOST OF CWA IN 12Z NAM...WHILE GFS CONSERVATIVELY            
BRUSHES ONLY NW PORTIONS AS LL JET TRANSLATES INTO MICHIGAN. COLD               
AIR ALOFT IS LAGGING AND STRONGER MID LEVEL WINDS ALSO REMAIN POST              
FRONTAL. NAM BUFR SOUNDINGS PRODUCE ONLY A THIN WINDOW OF                       
INSTABILITY WITH MUCAPES NEAR 300 J/KG ALONG WESTERN CWA DIMINISHING            
AS BNDRY TRANSLATES EAST IN A 30-40KT 0-3KM BULK SHEAR ENVIRONMENT.             
SIGNS POINT TO A POSSIBLE LINE OF WEAK/MODERATE CONVECTION                      
APPROACHING FROM THE WEST ALONG OR JUST AHEAD OF BNDRY IN AN AXIS OF            
STRONGEST LL MOISTURE CONVERGENCE...WEAKENING AS IT MOVES EWARD                 
THROUGH THE CWA. CONCERN IS FOR STRONG WIND GUSTS POSSIBLE WITH 40              
KT WINDS ALOFT WHICH COULD MIX DOWN...PARTICULARLY NORTHWEST CWA                
WHERE THERE IS BETTER CHANCE OF WEAK INSTABILITY BEING REALIZED.                
MAINTAINED OVERALL THEME OF POP/SKY WITH TWEAKS FOR INITIAL TIMING              
IN THE WEST AS WELL AS CLEARING BEYOND 06Z AS DRY SLOT MOVES INTO               
THE AREA BEHIND THE BNDRY. OVERNIGHT TEMPS REMAIN SIMILAR TO                    
PREVIOUS NIGHTS WITH COLDER AIR NOT ARRIVING IMMEDIATELY BEHIND                 
PASSAGE.

NAM/GFS VARY IN TRACK OF THE UPPER LOW AND ASSOCIATED POOL OF COLD              
AIR. THE TRACK WILL PLAY A KEY ROLE FOR PRECIP CHANCES MAINLY SAT               
AND SUNDAY.                                                                     
AT THE START OF THE PERIOD MODELS SHOW A LARGE GRADIENT IN 850 TEMPS            
FROM WEST TO EAST IN THE WAKE OF THE OCCLUDED FRONT WITH VALUES                 
RANGING FROM +1 WEST TO +8 C EAST. UPPER LOW ON THE NAM IS PROGGED              
TO BE CENTERED OVER SOUTHERN MINNESOTA WITH GFS OVER NW IOWA. MODELS            
GENERALLY AGREE ON WHAT APPEARS TO BE A NICE DRY SLOT IN BETWEEN THE            
OCCLUDED FRONT AND THE MAIN TROUGH AND UPPER LOW. 850 MB TEMPS LOWER            
AS THEY SPREAD ACROSS THE CWA BUT THEN SLOW AS THE UPPER LOW BEGINS             
TO SLOW ITS EASTWARD PROGRESS SOME. THIS WILL MAKE FOR A PROBLEMATIC            
TEMP FORECAST ON FRIDAY WITH TEMPS ACTUALLY WARMING BACK INTO THE               
UPPER 50S TO LOWER 60S INTO EARLY AFTERNOON. AFTER COLLABORATION...             
HAVE DECIDED TO ADD SOME DETAIL TO FRIDAY AND REMOVE POPS FOR PARTS             
OF THE DAY WITH LINGERING POPS EAST EARLY THEN A DRY PERIOD FOR ALL             
FOLLOW BY CHC POPS ARRIVING BACK IN THE NW LATE.                                
BY 12Z SAT...MODELS VARY EVEN GREATER ON LOCATION OF UPPER LOW WITH             
GFS HAVING THE LOW OVER SW LWR MI WITH 500 MB TEMPS OF -22 TO -26 C             
AND THE NAM FURTHER WEST AND NORTH OVER SOUTHERN WISCONSIN AND 500              
MB TEMPS OF -23 TO -26 C.  LATE FRI NGT INTO SATURDAY APPEARS TO BE             
THE NEXT BEST WINDOW FOR PRECIP WITH S/W ROUNDING THE                           
TROUGH...COLDEST AIR ALOFT OVERHEAD AND FAVORABLE TIME OF DAY. MAY              
NEED TO INCREASE POPS FURTHER BUT FOR NOW HAVE WENT HIGH CHC NORTH              
TO LOW CHC SOUTH FOR SATURDAY. THERMAL PROFILES WILL ALSO BE A                  
CHALLENGE WITH SOME HINTS OF MAYBE HAVING TO MIX IN A CHC OF SNOW               
AS 1000-850 MB THICKNESSES DROP TO AROUND 1290 M. NO CHANGES BEYOND             
THAT AS NEXT PUSH OF COLD AIR TO ARRIVE ON SUNDAY AND MONDAY.                   
CONCERNED THAT TEMPS MAY NOT BE COLD ENOUGH POSSIBLY INTO MONDAY                
WITH BUFKIT SOUNDINGS SUGGESTING HIGHS STRUGGLING TO CLIMB OUT OF               
THE 30S IN SOME AREAS. WILL HOLD POPS THROUGH SUNDAY BUT SOME CHANCE            
THAT THINGS COULD NEED TO BE EXPANDED IN COLD NW FLOW AND POTENTIAL             
SETUP FOR LAKE EFFECT AGAIN.                                                    
HIGH PRESSURE WILL EVENTUALLY BUILD IN COMPLETELY AND BRING AN END              
TO THE PRECIP CHANCES AND ALSO APPEARS TO KEEP THE NEXT SYSTEM                  
COMPRESSED TO THE SOUTH AT THIS POINT. SO WILL GO DRY INTO THE NEW              
DAY 7.

17Z WATER VAPOR IMAGERY/RUC ANALYSIS INDICATE A DEEP CLOSED H5 LOW              
ACROSS NORTHEAST NEBRASKA. AT THE SFC...THERE APPEARS TO BE TWO LOW             
CENTERS...A 997 MB CENTER NEAR KOFK AND A 994 MB LOW NEAR KMSP.                 
IMMEDIATE SHORT TERM CONCERNS WILL CONTINUE TO BE STRONG WINDS ON               
BACKSIDE OF THE SFC LOW. FOLLOWED BY POTENTIAL WINTER WX SUNDAY AND             
MONDAY.                                                                         
TONIGHT...DIV Q FIELDS INDICATE FORCING FOR SUBSIDENCE WILL BE IN               
PLACE INITIALLY ACROSS THE AREA AS H5 LOW SLOWLY MOVES TO THE EAST              
SOUTHEAST. SURPRISINGLY...DIV Q FIELDS AND OMEGA PROFILES INDICATE              
ASCENT OVERSPREADING THE AREA DURING THE EVENING. STATIC STABILITY              
APPEARS TO BE RATHER HIGH...AND DO NOT THINK WEAK FORCING WILL                  
PRODUCE MORE THAN A MIDDLE CLOUD DECK...SO WILL CONTINUE FORECAST OF            
PRECIP ENDING BY THIS AFTERNOON UNLESS OBSERVATIONAL TRENDS SUGGEST             
OTHERWISE. BOTH NAM AND GFS SUGGEST WINDS WILL DECOUPLE QUICKLY THIS            
EVENING AS SFC LOW CONTINUES TO MOVE EAST AND SUBSIDENCE BELOW H7               
HELPS STRENGTHEN THE INVERSION AND LIMIT TURBULENT MIXING. BUFR                 
SOUNDINGS SHOW A RESURGENCE IN THE WINDS AROUND 06Z AT MCK...AS WEAK            
ASCENT OVERSPREADS THE REGION. TIME OF NIGHT WOULD NOT SEEM TO FAVOR            
AN ATMOSPHERE AS DEEPLY MIXED AS THE SOUNDING SUGGEST AND FOR NOW               
WILL LET THE WARNING EXPIRE AS IS AND LET OBSERVATIONS DICTATE IF IT            
NEEDS TO BE EXTENDED.                                                           
TOMORROW-TOMORROW NIGHT...WINDS WILL LIKELY BE A FACTOR AGAIN ON                
FRIDAY...ALTHOUGH THEY WILL BE MUCH LIGHTER THAN TODAY. SUSTAINED               
WINDS AROUND 25KTS LOOK LIKELY ACROSS THE EASTERN CWA THROUGH THE               
DAY...AND MAY SEE WINDS REACH LOW END ADVISORY AROUND 18Z. WITH WIND            
HIGHLIGHTS ALREADY ONGOING...AND MARGINAL NATURE OF THE WINDS                   
TOMORROW...WILL NOT ISSUE AN ADDITIONAL HIGHLIGHT AT THIS TIME. SKIES           
SHOULD BE CLEAR FOR MUCH OF THE MORNING...BUT APPROACHING H3 JET                
STREAK WILL LIKELY PROVIDE ENOUGH LIFT FOR ANOTHER BATCH OF CLOUDS              
AS LARGE T-TD SPREADS AND A FAIRLY STABLE AIR MASS WILL LIMIT ANT               
PRECIPITATION CHANCE WITH THE APPROACHING JET STREAK. VERY DRY AIR              
TO THE WEST MAY ALSO ADVECT INTO THE AREA TOMORROW AS WIND FIELD                
WILL HAVE A WESTERLY COMPONENT IN THE MORNING. RH VALUES MAY NEAR               
CRITICAL FIRE WX VALUES DURING THE AFTERNOON ACROSS THE SOUTHWEST.              
THIS AREA WILL BE WHERE WINDS ARE THE LIGHTEST...SIMILAR TO TODAY.              
ALTHOUGH HAVE SOME CONCERNS ABOUT RED FLAG CRITERIA                             
TOMORROW...CONFIDENCE NOT HIGH ENOUGH FOR A WATCH ATTM...AND                    
SATURDAY-SUNDAY...SHORT WAVE RIDGING WILL BUILD OVER THE CWA ON                 
SATURDAY. DESPITE SUBSIDENCE WITH RIDGE...BOTH NAM AND GFS INDICATE             
PERSISTENT AREA OF SATURATION ALONG H7 THERMAL RIDGE IN AREA OF WAA.            
STATIC STABILITY ONCE AGAIN APPEARS STRONG SO DO NOT ANTICIPATE MUCH            
OF A PRECIP THREAT THROUGH THE DAY SATURDAY. NAM...GFS AND SREF ALL             
AGREE COLD FRONT WILL BACK INTO THE AREA SATURDAY AFTERNOON. MODELS             
STILL AGREE ON FAIRLY STRONG LOW LEVEL FORCING DEVELOPING OVERNIGHT             
AS WAA INCREASES ABOVE THE SHALLOW COLD AIRMASS. SOUNDINGS INDICATE             
ICE WOULD BE HARD TO COME BY AT MOST SITES WITH FORCING PRIMARILY               
FOCUSED SO LOW TO THE GROUND. ONE EXCEPTION TO THIS WILL BE IN THE              
NORTHEAST WHERE AFOREMENTIONED AREA OF SATURATION NEAR THE EDGE OF              
THERMAL RIDGE WHICH MAY BE ABLE TO PROVIDE A FEW ICE CRYSTALS BEFORE            
IT LIFTS NORTH SUNDAY MORNING. ALTHOUGH MODELS STILL SUPPORT THE                
POTENTIAL FOR -FZDZ OVERNIGHT SATURDAY INTO SUNDAY MORNING...MODELS             
STILL SUGGEST THAT BOUNDARY LAYER WILL NOT BE SATURATED WHICH WOULD             
LEAD ME TO THINK MORE STRATUS THAN ANY KIND OF PCP. MUCH DRIER                  
AIRMASS FORECASTED TO BE IN PLACE BEHIND THE FRONT...AND VERY                   
LIMITED MOISTURE RETURN NORTH OF THE FRONT SUPPORTS THIS LINE OF                
THINKING AS WELL. AT THIS POINT...THINK A SCHC STILL WARRANTED BUT              
DO NOT PLAN ON INCREASING CHANCES AT THIS TIME.                                 
IN THE EXTENDED(SUNDAY NIGHT-THURSDAY)...MEDIUM RANGE MODELS ALL                
HAVE THERE SHARE OF DIFFERENCES IN HANDLING OF NEXT SYSTEM ON                   
SUNDAY THROUGH TUESDAY. GFS ENSEMBLES FAVOR THE MORE AMPLIFIED                  
SOLUTION OF THE CANADIAN AND ECMWF AND WILL LEAN IN THIS DIRECTION              
FOR EXTENDED PERIODS ALTHOUGH CONFIDENCE REMAINS LOW. LOW CONFIDENCE            
ASIDE...POTENTIAL FOR ANOTHER WET PERIOD ACROSS CWA EXISTS. NUMEROUS            
DIFFERENCES IN MODEL FORECASTS MAKE DIAGNOSING SPECIFIC FORCING                 
DETAILS AND POTENTIAL PRECIPITATION TYPE DIFFICULT..AND FOR THE TIME            
BEING WILL TRY TO KEEP WX TYPE SIMPLE FOR MON-TUES. WITH CWA                    
EXPECTED TO BE ON THE NORTH SIDE OF LOW WITH DEEP EASTERLY FLOW AND             
PRECIP AND CLOUDS HOLDING BACK ANY WARMING DO NOT ANTICIPATE MUCH OF            
A DIURNAL TREND AND WILL COOL MAX TEMPS SEVERAL DEGREES. WITH A                 
LIMITED DIURNAL RANGE...AND GFS ENS DATA INDICATING >60% CHANCE OF              
H85 TEMPS BELOW 0C BY MONDAY AFTERNOON...WILL KEEP PRECIP TYPE AS               
SNOW FOR NOW. ANOTHER TROUGH IS FORECASTED TO IMPACT THE AREA LATTER            
IN THE PERIOD...BUT WITH ALL THE UNCERTAINTY OF THE FIRST HALF OF

17Z WATER VAPOR IMAGERY/RUC ANALYSIS INDICATE A DEEP CLOSED H5 LOW              
ACROSS NORTHEAST NEBRASKA. AT THE SFC...THERE APPEARS TO BE TWO LOW             
CENTERS...A 997 MB CENTER NEAR KOFK AND A 994 MB LOW NEAR KMSP.                 
IMMEDIATE SHORT TERM CONCERNS WILL CONTINUE TO BE STRONG WINDS ON               
BACKSIDE OF THE SFC LOW. FOLLOWED BY POTENTIAL WINTER WX SUNDAY AND             
MONDAY.                                                                         
TONIGHT...DIV Q FIELDS INDICATE FORCING FOR SUBSIDENCE WILL BE IN               
PLACE INITIALLY ACROSS THE AREA AS H5 LOW SLOWLY MOVES TO THE EAST              
SOUTHEAST. SURPRISINGLY...DIV Q FIELDS AND OMEGA PROFILES INDICATE              
ASCENT OVERSPREADING THE AREA DURING THE EVENING. STATIC STABILITY              
APPEARS TO BE RATHER HIGH...AND DO NOT THINK WEAK FORCING WILL                  
PRODUCE MORE THAN A MIDDLE CLOUD DECK...SO WILL CONTINUE FORECAST OF            
PRECIP ENDING BY THIS AFTERNOON UNLESS OBSERVATIONAL TRENDS SUGGEST             
OTHERWISE. BOTH NAM AND GFS SUGGEST WINDS WILL DECOUPLE QUICKLY THIS            
EVENING AS SFC LOW CONTINUES TO MOVE EAST AND SUBSIDENCE BELOW H7               
HELPS STRENGTHEN THE INVERSION AND LIMIT TURBULENT MIXING. BUFR                 
SOUNDINGS SHOW A RESURGENCE IN THE WINDS AROUND 06Z AT MCK...AS WEAK            
ASCENT OVERSPREADS THE REGION. TIME OF NIGHT WOULD NOT SEEM TO FAVOR            
AN ATMOSPHERE AS DEEPLY MIXED AS THE SOUNDING SUGGEST AND FOR NOW               
WILL LET THE WARNING EXPIRE AS IS AND LET OBSERVATIONS DICTATE IF IT            
NEEDS TO BE EXTENDED.                                                           
TOMORROW-TOMORROW NIGHT...WINDS WILL LIKELY BE A FACTOR AGAIN ON                
FRIDAY...ALTHOUGH THEY WILL BE MUCH LIGHTER THAN TODAY. SUSTAINED               
WINDS AROUND 25KTS LOOK LIKELY ACROSS THE EASTERN CWA THROUGH THE               
DAY...AND MAY SEE WINDS REACH LOW END ADVISORY AROUND 18Z. WITH WIND            
HIGHLIGHTS ALREADY ONGOING...AND MARGINAL NATURE OF THE WINDS                   
TOMORROW...WILL NOT ISSUE AN ADDITIONAL HIGHLIGHT AT THIS TIME. SKIES           
SHOULD BE CLEAR FOR MUCH OF THE MORNING...BUT APPROACHING H3 JET                
STREAK WILL LIKELY PROVIDE ENOUGH LIFT FOR ANOTHER BATCH OF CLOUDS              
AS LARGE T-TD SPREADS AND A FAIRLY STABLE AIR MASS WILL LIMIT ANT               
PRECIPITATION CHANCE WITH THE APPROACHING JET STREAK. VERY DRY AIR              
TO THE WEST MAY ALSO ADVECT INTO THE AREA TOMORROW AS WIND FIELD                
WILL HAVE A WESTERLY COMPONENT IN THE MORNING. RH VALUES MAY NEAR               
CRITICAL FIRE WX VALUES DURING THE AFTERNOON ACROSS THE SOUTHWEST.              
THIS AREA WILL BE WHERE WINDS ARE THE LIGHTEST...SIMILAR TO TODAY.              
ALTHOUGH HAVE SOME CONCERNS ABOUT RED FLAG CRITERIA                             
TOMORROW...CONFIDENCE NOT HIGH ENOUGH FOR A WATCH ATTM...AND                    
SATURDAY-SUNDAY...SHORT WAVE RIDGING WILL BUILD OVER THE CWA ON                 
SATURDAY. DESPITE SUBSIDENCE WITH RIDGE...BOTH NAM AND GFS INDICATE             
PERSISTENT AREA OF SATURATION ALONG H7 THERMAL RIDGE IN AREA OF WAA.            
STATIC STABILITY ONCE AGAIN APPEARS STRONG SO DO NOT ANTICIPATE MUCH            
OF A PRECIP THREAT THROUGH THE DAY SATURDAY. NAM...GFS AND SREF ALL             
AGREE COLD FRONT WILL BACK INTO THE AREA SATURDAY AFTERNOON. MODELS             
STILL AGREE ON FAIRLY STRONG LOW LEVEL FORCING DEVELOPING OVERNIGHT             
AS WAA INCREASES ABOVE THE SHALLOW COLD AIRMASS. SOUNDINGS INDICATE             
ICE WOULD BE HARD TO COME BY AT MOST SITES WITH FORCING PRIMARILY               
FOCUSED SO LOW TO THE GROUND. ONE EXCEPTION TO THIS WILL BE IN THE              
NORTHEAST WHERE AFOREMENTIONED AREA OF SATURATION NEAR THE EDGE OF              
THERMAL RIDGE WHICH MAY BE ABLE TO PROVIDE A FEW ICE CRYSTALS BEFORE            
IT LIFTS NORTH SUNDAY MORNING. ALTHOUGH MODELS STILL SUPPORT THE                
POTENTIAL FOR -FZDZ OVERNIGHT SATURDAY INTO SUNDAY MORNING...MODELS             
STILL SUGGEST THAT BOUNDARY LAYER WILL NOT BE SATURATED WHICH WOULD             
LEAD ME TO THINK MORE STRATUS THAN ANY KIND OF PCP. MUCH DRIER                  
AIRMASS FORECASTED TO BE IN PLACE BEHIND THE FRONT...AND VERY                   
LIMITED MOISTURE RETURN NORTH OF THE FRONT SUPPORTS THIS LINE OF                
THINKING AS WELL. AT THIS POINT...THINK A SCHC STILL WARRANTED BUT              
DO NOT PLAN ON INCREASING CHANCES AT THIS TIME.                                 
IN THE EXTENDED(SUNDAY NIGHT-THURSDAY)...MEDIUM RANGE MODELS ALL                
HAVE THERE SHARE OF DIFFERENCES IN HANDLING OF NEXT SYSTEM ON                   
SUNDAY THROUGH TUESDAY. GFS ENSEMBLES FAVOR THE MORE AMPLIFIED                  
SOLUTION OF THE CANADIAN AND ECMWF AND WILL LEAN IN THIS DIRECTION              
FOR EXTENDED PERIODS ALTHOUGH CONFIDENCE REMAINS LOW. LOW CONFIDENCE            
ASIDE...POTENTIAL FOR ANOTHER WET PERIOD ACROSS CWA EXISTS. NUMEROUS            
DIFFERENCES IN MODEL FORECASTS MAKE DIAGNOSING SPECIFIC FORCING                 
DETAILS AND POTENTIAL PRECIPITATION TYPE DIFFICULT..AND FOR THE TIME            
BEING WILL TRY TO KEEP WX TYPE SIMPLE FOR MON-TUES. WITH CWA                    
EXPECTED TO BE ON THE NORTH SIDE OF LOW WITH DEEP EASTERLY FLOW AND             
PRECIP AND CLOUDS HOLDING BACK ANY WARMING DO NOT ANTICIPATE MUCH OF            
A DIURNAL TREND AND WILL COOL MAX TEMPS SEVERAL DEGREES. WITH A                 
LIMITED DIURNAL RANGE...AND GFS ENS DATA INDICATING >60% CHANCE OF              
H85 TEMPS BELOW 0C BY MONDAY AFTERNOON...WILL KEEP PRECIP TYPE AS               
SNOW FOR NOW. ANOTHER TROUGH IS FORECASTED TO IMPACT THE AREA LATTER            
IN THE PERIOD...BUT WITH ALL THE UNCERTAINTY OF THE FIRST HALF OF

SATISFY CRITERIA FOR A WIND ADVISORY ON THURSDAY OVER THE CWA. THE              
NAM AND GFS FORECAST SOUNDINGS INDICATE SUSTAINED WINDS OF 30+ KTS

NORTHEAST ZONES. THIS WILL CONTINUE THROUGH ABOUT 18Z THURSDAY.                 
CONSEQUENTLY HAVE RELIED ON SLIGHT CHANCE POPS FOR THESE BASED UPON             
MARGINAL NATURE OF THIS SYSTEM SO FAR. HOWEVER EXPECT WRAPAROUND TO             
HAVE BETTER MOISTURE THURSDAY MORNING AND FOR THAT REASON HAVE                  
INCREASE POPS TO CHANCE OVER THE MCK AREA. FORECAST SOUNDINGS                   
INDICATE PRECIPITATION EAST OF COLORADO SHOULD BE LIQUID BUT CANNOT             
RULE OUT SOME SNOW MIXING IN OVER YUMA COUNTY COLORADO. SOUNDINGS

THE UPPER LOW IS PROGGED TO MOVE NORTHEAST INTO CENTRAL SOUTH DAKOTA            
TONIGHT. NORTHWEST FLOW WILL TAKE OVER ON THURSDAY AND CONTINUE                 
THROUGH SATURDAY. SURFACE HIGH PRESSURE WILL BUILD EASTWARD INTO THE

THE MAIN FORECAST ISSUES ARE WIND ON THURSDAY AND WHETHER ANY POPS

THE SURFACE PRESSURE GRADIENT TIGHTENS UP THURSDAY BEHIND THE                   
EXITING LOW PRESSURE. LATEST GUIDANCE INDICATES THAT WINDS WILL                 
SATISFY CRITERIA FOR A WIND ADVISORY ON THURSDAY OVER THE CWA. THE              
NAM AND GFS FORECAST SOUNDINGS INDICATE SUSTAINED WINDS OF 30+ KTS              
WITH POTENTIAL GUSTS TO 45KTS OVER MOST OF THE FORECAST AREA. THE               
RUC ALSO SUPPORTS THE WIND ADVISORY WITH SUSTAINED WINDS OF GREATER             
THAN 30KTS AND GUSTS GREATER THAN 40 KTS. BASED ON THIS HAVE ALREADY            
ISSUED A WIND ADVISORY FOR THE ENTIRE FORECAST AREA FOR                         
THURSDAY...SEE DETAILS BELOW.

THEN TOWARD 12Z THURSDAY WRAPAROUND DYNAMICS START TO AFFECT THE                
NORTHEAST ZONES. THIS WILL CONTINUE THROUGH ABOUT 18Z THURSDAY.                 
CONSEQUENTLY HAVE RELIED ON SLIGHT CHANCE POPS FOR THESE BASED UPON             
MARGINAL NATURE OF THIS SYSTEM SO FAR. HOWEVER EXPECT WRAPAROUND TO             
HAVE BETTER MOISTURE THURSDAY MORNING AND FOR THAT REASON HAVE                  
INCREASE POPS TO CHANCE OVER THE MCK AREA. FORECAST SOUNDINGS                   
INDICATE PRECIPITATION EAST OF COLORADO SHOULD BE LIQUID BUT CANNOT             
RULE OUT SOME SNOW MIXING IN OVER YUMA COUNTY COLORADO. SOUNDINGS               
ARE NOT ALL THAT SATURATED AT LOWER LEVELS SO PRECIPITATION MAY HAVE            
DIFFICULTY REACHING THE SURFACE. SUBSIDENCE TAKES OVER ACROSS THE               
ENTIRE FORECAST AREA THURSDAY NIGHT AND CONTINUES THROUGH SATURDAY.             
850MB TEMPERATURES WILL KEEP MAX TEMPERATURES COOL IN THE UPPER 40S ON          
THURSDAY. TEMPERATURES WILL START MODERATING ON FRIDAY WITH ABOVE               
NORMAL READINGS NEAR 60 ON SATURDAY. MIN TEMPERATURES WILL FALL INTO            
THE UPPER 20S TO LOWER 30S TONIGHT THROUGH SATURDAY NIGHT.                      
IN THE EXTENDED...DIFFERENCES STILL REMAIN BETWEEN THE GFS AND THE              
ECMWF. THE GFS IS MUCH WEAKER WITH THE SYSTEM THAN THE ECMWF. THE               
ECMWF DIVES SOUTH AND THEN COMES BACK NORTH ACROSS THE FORECAST                 
AREA. DUE TO THE LACK OF AGREEMENT WILL CONTINUE SLIGHT CHANCE POPS             
FOR A RAIN/SNOW MIX FOR SUNDAY NIGHT THROUGH MONDAY NIGHT ESPECIALLY            
SINCE THE GFS HAS WEAK DYNAMICS. 850 TEMPERATURES FALL BELOW ZERO ON            
MONDAY AND STAY COLD THROUGH WEDNESDAY. MAX TEMPERATURES START IN

.SHORT TERM (TONIGHT AND FRIDAY)...                                             
UPPER TROUGH WILL CONTINUE TO DIG S ACROSS SRN PLAINS TONIGHT AND               
GRADUALLY MERGE WITH THE SUB TROPICAL JET LATER IN THE DAY ON FRI.              
WITH THE TROUGH DIGGING DEEP OVER THE CNTRL US...DUE TO H250 100KT              
JET MOVING SE OVER THE ROCKIES...IT PULLS THE UPPER SUPPORT JUST                
FAR ENOUGH AWAY FROM SFC LOW TO ALLOW IT TO GRADUALLY WEAKEN AND                
DRIFT NE THROUGH THE SHORT TERM PERIOD.                                         
EXPECT THE PCPN TO CONTINUE NORTH DURING THE LATE AFTN HRS. DRY                 
AIR MENTIONED PREVIOUSLY SHOULD QUICKLY BE EATEN AWAY ACROSS THE                
REST OF THE CWA BY ABUNDANT H900 AND ABOVE MOISTURE MOVING IN FROM              
WI...AS SEEN ON WV IMAGERY AND CNTRL WI TAMDAR SOUNDINGS. HAVE LEFT             
MENTION OF ISOLATED THUNDER IN FOR THE LATE AFTN...AS STEEP LAPSE               
RATES ABOVE H850 WERE SEEN ON 18Z KCWA TAMDAR SOUNDING...BUT HAVE               
NOT SEEN ANY LIGHTING STRIKES IN NRN WI SO FAR. THIS MOISTURE IS                
SITUATED AHEAD OF SFC COLD/OCCLUDED FRONT THAT WILL PUSH N THROUGH              
CWA...MAINLY THIS EVENING. MOISTURE IS ABUNDANT FOR THIS TIME OF                
YEAR...WITH PWAT VALUES NEAR OR ABOVE AN INCH...WHICH IS 200-300                
PERCENT OF NORMAL. SHOULD BE PLENTY OF FORCING ALONG THE                        
FRONT...WITH 290-305K ISENTROPIC SFCS SHOWING WELL DEFINED                      
BOUNDARY PUSHING NE THROUGH WRN HALF OF CWA BY 06Z AND THEN OVER                
THE FAR ERN CWA BY 12Z FRI...AND DECENT H850-500 Q VECTOR                       
CONVERGENCE. THEREFORE...EXPECT NW TO SE ORIENTATED BAND OF                     
SHOWERS TO TRANSITION FROM SW TO NE ACROSS THE CWA...WITH BEST                  
PCPN CHANCES OVER THE WRN UP DURING THE EVENING AND ERN UP INTO                 
THE OVERNIGHT HOURS. EXPECT THE WIDTH OF THE PCPN TO SHRINK                     
TONIGHT...AS DRY AIR AHEAD OF THE FRONT AND DRY SLOT MOVING IN                  
FROM BEHIND TO PINCH THE MOISTURE FIELD INTO FRI MORN. EXISTING                 
FORECAST HAD PRETTY GOOD TIMING ON PCPN...SO DID NOT MAKE MANY                  
ADJUSTMENTS. CONTINUED THE DECREASING CLOUDS OVERNIGHT FROM SW TO NE            
ACROSS THE CWA. SHOULD SEE A PERIOD OF PARTLY CLOUDY SKIES MOVING               
THROUGH THE CWA BEHIND THE FRONT...BEFORE UPPER LOW MOVES CLOSE                 
ENOUGH TO MOVE H850-700 MOISTURE/CLOUDS OVER THE KIWD AREA LATE                 
TONIGHT.                                                                        
LOW PRESSURE SYSTEM NEARLY BECOMES VERTICALLY STACKED DURING THE                
DAY ON FRI...AS IT DRIFTS TO THE SE. LOOKS LIKE THERE WILL BE A                 
BROAD AREA OF CLOUDS AND SHOWERS ACROSS MN AND WI...AS COLD H850                
TEMPS NEARLY WRAP ALL THE WAY AROUND THE LOW. BEST CHANCE OF PCPN               
TOMORROW LOOKS TO BE S AND W OF A LINE FROM KCMX TO KESC...MAINLY               
IN THE AFTN AS H850 COLD NOSE MOVES N INTO THE AREA AND SFC LOW                 
MOVES TO JUST N OF KIWD. EXPECT A FEW SHOWERS TO DEVELOP THROUGH                
THE DAY. WITH COLD AIR ALOFT MOVING AROUND THE LOW...IT SHOULD                  
PRODUCE FAIRLY STEEP LLVL LAPSE RATES BETWEEN SFC AND H750                      
INVERSION. THIS COMBINED WITH PLENTY OF MOISTURE BELOW THE                      
INVERSION...SHOULD ALLOW SHOWERS TO DEVELOP ACROSS THE SW PART OF               
THE CWA AND GRADUALLY SHIFT NE. DID EXPAND THE CHANCE PCPN AREA                 
FARTHER TO THE NE DURING THE AFTN...BUT LEFT THE FAR ERN CWA IN                 
SLIGHT CHANCES DUE TO DRY SLOT STILL WORKING OUT OF THAT AREA.                  
OVERALL...EXPECT THE SHOWERS TO BE HIT OR MISS...WITH QPF BEING                 
LIGHT DUE TO LIMITED CLOUD DEPTH. ADDED SOME SLIGHT CHANCES OF                  
SNOW ALONG THE WI BORDER AREA FOR LATE TOMORROW AFTN. H850 TEMPS                
DROP FROM -2C AT 18Z FRI TO AROUND -5-6C AT 0Z. SFC TEMPS SHOULD                
ALSO DROP DURING THE AFTN ALONG THE WI BORDER...WITH VALUES IN THE              
UPPER 30S BY 00Z. WBZ HEIGHTS WILL DROP BELOW 1.5KFT AGL BETWEEN                
21-00Z ON NAM AND LOCAL HI-RES WRF-ARW. SO WOULD NOT BE SURPRISED               
IF PCPN MIXED WITH SNOW IN THE STRONGER SHOWERS LATE IN THE DAY                 
FRI.                                                                            
LONGER TERM...00Z SAT ONWARD...                                                 
NAM SHOWS THE CLOSED 500 MB LOW AND TROUGH AFFECTING THE UPPER GREAT            
LAKES 00Z SAT AND THEN SLOWLY TAKES THE LOW EAST WITH THE LOW                   
CROSSING NORTHERN LAKE MICHIGAN ON SAT. MORE SHORTWAVE ENERGY DROPS             
DOWN THE BACKSIDE OF THE TROUGH SAT NIGHT AND SUN AND HELPS KEEP THE            
CLOSED 500 MB LOW FROM MOVING TO FAR TO THE EAST OF THE LAKE                    
SUPERIOR REGION. NAM SHOWS SOME WEAK 850-500 MB Q-VECTOR CONVERGENCE            
PASSING ACROSS THE CWA FRI NIGHT WITH AMPLE MOISTURE AND THEN THE               
CONVERGENCE STAYS OVER THE NORTH AND EASTERN CWA ON SAT. NAM SHOWING            
SOME ISENTROPIC LIFT ON I280K-I295K SURFACES AND MOISTURE FRI NIGHT             
WITH LIFT MOVING OUT SAT NIGHT. SYSTEM IS REALLY WRAPPED UP ON THE              
ISENTROPIC SURFACES. COLD AIR WILL COME IN SLOWLY FROM THE SW FOR               
FRI NIGHT AND PUT IN SOME SNOW MIX FOR THE WEST HALF. BEST MOISTURE             
IS GONE THEN...BUT COULD STILL SEE UP TO 2 INCHES OF SNOW IN A FEW              
SPOTS FOR FRI NIGHT ANYWAY. COLD AIR SLOWLY MOVES EAST ON SAT...BUT             
DOES NOT GET INTO THE FAR EASTERN CWA UNTIL SAT EVENING. MOISTURE IS            
STILL NOT THAT PLENTIFUL ON SAT...BUT COULD SEE ANOTHER 2 INCHES                
ACROSS THE WEST. LAKE EFFECT REALLY GETS GOING THEN AS IT IS COLD               
ENOUGH AT 850 MB TO ADD SOME LAKE MOISTURE INTO THE EQUATION AS                 
WINDS TURN TO THE NORTH DURING THE DAY. OVERALL...BESIDES MOVING THE            
COLD AIR IN QUICKER AND CHANGING THE PCPN OVER TO SNOW QUICKER OVER             
THE WEST...DID NOT MAKE MANY CHANGES TO THE GOING FORECAST.                     
IN THE EXTENDED...GFS...ECMWF AND CANADIAN ALL SHOW A 500 MB TROUGH             
AND LOW ACROSS THE UPPER GREAT LAKES 00Z MON WITH TROUGHING                     
REMAINING THROUGH 00Z TUE WHILE RIDGING BUILDS INTO THE NORTHERN                
PLAINS. THE RIDGE THEN MOVES IN FOR 00Z WED WITH ANOTHER TROUGH THEN            
FOR THU AFFECTING THE NORTHERN PLAINS. WILL KEEP LAKE EFFECT PCPN IN            
THROUGH TUE MORNING...THEN GO DRY THROUGH THE REST OF THE EXTENDED              
PERIOD. TEMPERATURES LOOK TO STAY NEAR NORMAL. DID NOT MAKE ANY HUGE            
CHANGES TO THE EXTENDED AS GOING FORECAST LOOKED PRETTY GOOD.

.AVIATION (FOR THE 00Z TAF ISSUANCE)...                                         
AN AREA OF SHOWERS WILL MOVE THROUGH WEST/CNTRL UPPER MI THIS                   
EVENING WITH MAINLY IFR TO MVFR CIGS/VSBYS...BEFORE COMING TO AN END            
AFTER 06Z TONIGHT.  KEPT LOWER VSBYS AND CIGS AFTER 06Z AT KSAW FOR             
A TIME...AS SE WINDS AND EXISTING MOISTURE SHOULD PRODUCE IFR TO                
LIFR CONDITIONS BELOW THE INVERSION AND DRY AIR ALOFT. BROUGHT THE              
CONDITIONS BACK UP TO VFR LATE TONIGHT AND TOMORROW MORNING AT BOTH             
SITES...AS DRIER AIR MOVES IN BEFORE ADDITIONAL SHOWERS LATER IN THE

SFC LOW OVER MN WILL SLOWLY DRIFT TO THE NE ACROSS THE UPPER GREAT              
LAKES THROUGH SATURDAY AFTN. EXPECT THE FEW NE GALE FORCE GUSTS                 
NEAR THE ARROWHEAD OF MN TO DIMINISH THIS EVENING...BUT MAY SEE                 
SOME GUSTS TO 30KTS EARLY AND SE GUSTS TO 30KTS ACROSS ERN                      
SUPERIOR THROUGH THE NIGHT. AS THE LOW MOVES ACROSS THE                         
AREA...WINDS SHOULD BE IN THE 15 TO 25 KNOTS RANGE...BEFORE                     
STRENGTHENING ON THE BACK SIDE OF THE LOW. EXPECT GALE FORCE GUSTS              
ACROSS MOST OF LAKE SUPERIOR ON SAT AND SUN. THE LOW WILL EXIT THE              
REGION ON SUN...WITH HIGH PRESSURE MOVING OVER THE WRN GREAT LAKES

FAR ENOUGH AWAY FROM SFC LOW TO ALLOW IT TO GRADUALLY WEAKEN AND                
DRIFT NE THROUGH THE SHORT TERM PERIOD.                                         
EXPECT THE PCPN TO CONTINUE NORTH DURING THE LATE AFTN HRS. DRY                 
AIR MENTIONED PREVIOUSLY SHOULD QUICKLY BE EATEN AWAY ACROSS THE                
REST OF THE CWA BY ABUNDANT H900 AND ABOVE MOISTURE MOVING IN FROM              
WI...AS SEEN ON WV IMAGERY AND CNTL WI TAMDAR SOUNDINGS. HAVE LEFT              
MENTION OF ISOLATED THUNDER IN FOR THE LATE AFTN...AS STEEP LAPSE               
RATES ABOVE H850 WERE SEEN ON 18Z KCWA TAMDAR SOUNDING...BUT HAVE               
NOT SEEN ANY LIGHTING STRIKES IN NRN WI SO FAR. THIS MOISTURE IS                
SITUATED AHEAD OF SFC COLD/OCCLUDED FRONT THAT WILL PUSH N THROUGH              
CWA...MAINLY THIS EVENING. MOISTURE IS ABUNDANT FOR THIS TIME OF                
YEAR...WITH PWAT VALUES NEAR OR ABOVE AN INCH...WHICH IS 200-300                
PERCENT OF NORMAL. SHOULD BE PLENTY OF FORCING ALONG THE                        
FRONT...WITH 290-305K ISENTROPIC SFCS SHOWING WELL DEFINED                      
BOUNDARY PUSHING NE THROUGH WRN HALF OF CWA BY 06Z AND THEN OVER                
THE FAR ERN CWA BY 12Z FRI...AND DECENT H850-500 Q VECTOR                       
CONVERGENCE. THEREFORE...EXPECT NW TO SE ORIENTATED BAND OF                     
SHOWERS TO TRANSITION FROM SW TO NE ACROSS THE CWA...WITH BEST                  
PCPN CHANCES OVER THE WRN UP DURING THE EVENING AND ERN UP INTO                 
THE OVERNIGHT HOURS. EXPECT THE WIDTH OF THE PCPN TO SHRINK                     
TONIGHT...AS DRY AIR AHEAD OF THE FRONT AND DRY SLOT MOVING IN                  
FROM BEHIND TO PINCH THE MOISTURE FIELD INTO FRI MORN. EXISTING                 
FORECAST HAD PRETTY GOOD TIMING ON PCPN...SO DID NOT MAKE MANY                  
ADJUSTMENTS. CONTINUED THE DECREASING CLOUDS OVERNIGHT FROM SW TO NE            
ACROSS THE CWA. SHOULD SEE A PERIOD OF PARTLY CLOUDY SKIES MOVING               
THROUGH THE CWA BEHIND THE FRONT...BEFORE UPPER LOW MOVES CLOSE                 
ENOUGH TO MOVE H850-700 MOISTURE/CLOUDS OVER THE KIWD AREA LATE                 
TONIGHT.                                                                        
LOW PRESSURE SYSTEM NEARLY BECOMES VERTICALLY STACKED DURING THE                
DAY ON FRI...AS IT DRIFTS TO THE SE. LOOKS LIKE THERE WILL BE A                 
BROAD AREA OF CLOUDS AND SHOWERS ACROSS MN AND WI...AS COLD H850                
TEMPS NEARLY WRAP ALL THE WAY AROUND THE LOW. BEST CHANCE OF PCPN               
TOMORROW LOOKS TO BE S AND W OF A LINE FROM KCMX TO KESC...MAINLY               
IN THE AFTN AS H850 COLD NOSE MOVES N INTO THE AREA AND SFC LOW                 
MOVES TO JUST N OF KIWD. EXPECT A FEW SHOWERS TO DEVELOP THROUGH                
THE DAY. WITH COLD AIR ALOFT MOVING AROUND THE LOW...IT SHOULD                  
PRODUCE FAIRLY STEEP LLVL LAPSE RATES BETWEEN SFC AND H750                      
INVERSION. THIS COMBINED WITH PLENTY OF MOISTURE BELOW THE                      
INVERSION...SHOULD ALLOW SHOWERS TO DEVELOP ACROSS THE SW PART OF               
THE CWA AND GRADUALLY SHIFT NE. DID EXPAND THE CHANCE PCPN AREA                 
FARTHER TO THE NE DURING THE AFTN...BUT LEFT THE FAR ERN CWA IN                 
SLIGHT CHANCES DUE TO DRY SLOT STILL WORKING OUT OF THAT AREA.                  
OVERALL...EXPECT THE SHOWERS TO BE HIT OR MISS...WITH QPF BEING                 
LIGHT DUE TO LIMITED CLOUD DEPTH. ADDED SOME SLIGHT CHANCES OF                  
SNOW ALONG THE WI BORDER AREA FOR LATE TOMORROW AFTN. H850 TEMPS                
DROP FROM -2C AT 18Z FRI TO AROUND -5-6C AT 0Z. SFC TEMPS SHOULD                
ALSO DROP DURING THE AFTN ALONG THE WI BORDER...WITH VALUES IN THE              
UPPER 30S BY 00Z. WBZ HEIGHTS WILL DROP BELOW 1.5KFT AGL BETWEEN                
21-00Z ON NAM AND LOCAL HI-RES WRF-ARW. SO WOULD NOT BE SURPRISED               
IF PCPN MIXED WITH SNOW IN THE STRONGER SHOWERS LATE IN THE DAY                 
FRI.                                                                            
LONGER TERM...00Z SAT ONWARD...

LAKES 00Z SAT AND THEN SLOWLY TAKES THE LOW EAST WITH THE LOW                   
CROSSING NORTHERN LAKE MICHIGAN ON SAT. MORE SHORTWAVE ENERGY DROPS             
DOWN THE BACKSIDE OF THE TROUGH SAT NIGHT AND SUN AND HELPS KEEP THE            
CLOSED 500 MB LOW FROM MOVING TO FAR TO THE EAST OF THE LAKE                    
SUPERIOR REGION. NAM SHOWS SOME WEAK 850-500 MB Q-VECTOR CONVERGENCE            
PASSING ACROSS THE CWA FRI NIGHT WITH AMPLE MOISTURE AND THEN THE               
CONVERGENCE STAYS OVER THE NORTH AND EASTERN CWA ON SAT. NAM SHOWING            
SOME ISENTROPIC LIFT ON I280K-I295K SURFACES AND MOISTURE FRI NIGHT             
WITH LIFT MOVING OUT SAT NIGHT. SYSTEM IS REALLY WRAPPED UP ON THE              
ISENTROPIC SURFACES. COLD AIR WILL COME IN SLOWLY FROM THE SW FOR               
FRI NIGHT AND PUT IN SOME SNOW MIX FOR THE WEST HALF. BEST MOISTURE             
IS GONE THEN...BUT COULD STILL SEE UP TO 2 INCHES OF SNOW IN A FEW              
SPOTS FOR FRI NIGHT ANYWAY. COLD AIR SLOWLY MOVES EAST ON SAT...BUT             
DOES NOT GET INTO THE FAR EASTERN CWA UNTIL SAT EVENING. MOISTURE IS            
STILL NOT THAT PLENTIFUL ON SAT...BUT COULD SEE ANOTHER 2 INCHES                
ACROSS THE WEST. LAKE EFFECT REALLY GETS GOING THEN AS IT IS COLD               
ENOUGH AT 850 MB TO ADD SOME LAKE MOISTURE INTO THE EQUATION AS                 
WINDS TURN TO THE NORTH DURING THE DAY. OVERALL...BESIDES MOVING THE            
COLD AIR IN QUICKER AND CHANGING THE PCPN OVER TO SNOW QUICKER OVER             
THE WEST...DID NOT MAKE MANY CHANGES TO THE GOING FORECAST.                     
IN THE EXTENDED...GFS...ECMWF AND CANADIAN ALL SHOW A 500 MB TROUGH             
AND LOW ACROSS THE UPPER GREAT LAKES 00Z MON WITH TROUGHING                     
REMAINING THROUGH 00Z TUE WHILE RIDGING BUILDS INTO THE NORTHERN                
PLAINS. THE RIDGE THEN MOVES IN FOR 00Z WED WITH ANOTHER TROUGH THEN            
FOR THU AFFECTING THE NORTHERN PLAINS. WILL KEEP LAKE EFFECT PCPN IN            
THROUGH TUE MORNING...THEN GO DRY THROUGH THE REST OF THE EXTENDED              
PERIOD. TEMPERATURES LOOK TO STAY NEAR NORMAL. DID NOT MAKE ANY HUGE            
CHANGES TO THE EXTENDED AS GOING FORECAST LOOKED PRETTY GOOD.

.AVIATION (FOR THE 18Z TAF ISSUANCE)...                                         
A QUIET FIRST PART OF THE TAF PERIOD IS EXPECTED...AS CIRRUS MOVE               
OVER BOTH TAF SITES. AREA OF SHOWERS CURRENTLY STRETCHING FROM KDLH             
TO KRHI...TO KOSH...WILL CONTINUE TO ROTATE NORTH AND START                     
AFFECTING THE TAF SITES AFTER 22Z. EXPECT THE PCPN TO CONTINUE OFF              
AND ON THROUGH THE EVENING HOURS...WITH MAINLY IFR TO MVFR                      
CIGS/VSBYS...BEFORE COMING TO AN END AFTER 06Z TONIGHT.  KEPT LOWER             
VSBYS AND CIGS AFTER 06Z AT KSAW FOR A TIME...AS SE WINDS AND                   
EXISTING MOISTURE SHOULD PRODUCE IFR TO LIFR CONDITIONS BELOW THE               
INVERSION AND DRY AIR ALOFT. BROUGHT THE CONDITIONS BACK UP TO VFR              
LATE TONIGHT AND TOMORROW MORNING AT BOTH SITES...AS DRIER AIR MOVES            
IN BEFORE ADDITIONAL SHOWERS LATER IN THE DAY. ALSO KEPT THE MENTION            
OF WIND SHEAR IN LATE THIS EVENING AND INTO THE OVERNIGHT HOURS...AS            
STRONG JET ALOFT OF 35-45KTS SLIDE THROUGH.

SFC LOW OVER MN WILL SLOWLY DRIFT TO THE NE ACROSS THE UPPER GREAT

NEAR THE ARROWHEAD OF MN TO DIMINISH THIS EVENING...BUT MAY SEE                 
SOME GUSTS TO 30KTS EARLY AND SE GUSTS TO 30KTS ACROSS ERN                      
SUPERIOR THROUGH THE NIGHT. AS THE LOW MOVES ACROSS THE                         
AREA...WINDS SHOULD BE IN THE 15 TO 25 KNOTS RANGE...BEFORE                     
STRENGTHENING ON THE BACK SIDE OF THE LOW. EXPECT GALE FORCE GUSTS              
ACROSS MOST OF LAKE SUPERIOR ON SAT AND SUN. THE LOW WILL EXIT THE              
REGION ON SUN...WITH HIGH PRESSURE MOVING OVER THE WRN GREAT LAKES

WATER VAPOR IMAGERY AND RUC SHOWING A LOW CENTER EMBEDDED IN DEEP               
TROUGH OVER NORTHERN AND MIDDLE HIGH PLAINS. WEAK SHORTWAVES EJECTED            
OUT AHEAD OF THIS TROUGH ARE OVER CENTRAL MINNESOTA INTO CENTRAL                
ONTARIO. DEEPER SHORTWAVES ARE OVER WESTERN NEBRASKA. SURFACE                   
ANALYSIS DEPICTS A CLOSED LOW NEAR KFSD. A FRONTAL SYSTEM EXTENDS               
NORTHEAST FROM THE LOW THROUGH NORTHERN MINNESOTA TO SOUTHERN TIP OF            
JAMES BAY...WHILE A COLD FRONT DRAPES SOUTH THE CENTRAL PLAINS. A               
STRONG SOUTHERLY FLOW AHEAD OF THE LOW CONTINUES TO DRAW WARM MOIST             
AIR INTO THE FORECAST AREA. ISENTROPIC ASCENT...SHORTWAVE ENERGY AND            
LOW LEVEL MOISTURE ARE GENERATE SOME THUNDERSTORMS OVER MINNESOTA               
AND IOWA THIS AFTERNOON.

.SHORT TERM (TONIGHT AND THURSDAY)...                                           
THE MID LEVEL WILL OVER WESTERN NEBRASKA WILL SHIFT EAST INTO                   
EASTERN NEBRASKA. SHORTWAVE ENERGY WILL SHIFT THROUGH MINNESOTA AND             
WESTERN U.P. THIS AFTERNOON REACHING NORTHEAST NEBRASKA OVERNIGHT.              
THE SURFACE LOW WILL BECOME MORE FOCUSED OVER NORTHERN IOWA AND                 
SOUTHERN MINNESOTA TONIGHT. A FRONTAL SYSTEM LEADING THIS LOW WILL              
CONTINUE TO STRETCH NORTHEAST BUT WILL START TO SETTLE SOUTH INTO               
WESTERN LAKE SUPERIOR OVERNIGHT. A TRAILING COLD FRONT WILL BE                  
DRAPED SOUTH INTO MIDDLE AND LOWER MISSISSIPPI RIVER VALLEY. WARM               
MOIST AIR WILL CONTINUE TO BE LIFTED NORTH AHEAD OF THE FRONTAL                 
SYSTEM. 850-500MB Q-VECTOR CONVERGENCE WILL BE CONFINED TO THE                  
WESTERN U.P. THIS AFTERNOON AND TONIGHT. A 45 TO 50 KNOT LOW LEVEL              
JET EAST OF THE FRONT WILL CONTINUE TO DRAW MORE MOISTURE INTO THE              
AREA. AN UPPER LEVEL JET MAX WILL BE OVER JAMES BAY AND EASTERN                 
NEBRASKA INTO SOUTHERN MINNESOTA. TOGETHER THESE ARE PRODUCING SOME             
UPPER LEVEL DIVERGENCE OF THE WESTERN U.P. TONIGHT. THUS WILL KEEP A            
CHANCE OF SHOWERS AND THUNDERSTORMS OVER THE WEST TONIGHT CLOSER TO             
THE FRONT AND LOW CENTER.                                                       
THE MID LEVEL LOW WILL LIFT INTO SOUTHWEST MINNESOTA. THE WEAK                  
SHORTWAVE EJECTED OUT OF THE BASE OF THE LOW WILL SWEEP INTO                    
SOUTHEAST MINNESOTA AND EASTERN IOWA. THE SURFACE LOW WILL LIFT                 
NORTH INTO CENTRAL MINNESOTA. THE COLD FRONT WILL LIFT OUT OF THE               
UPPER MISSISSIPPI RIVER VALLEY INTO NORTHEAST WISCONSIN ON THURSDAY.            
LOW LEVEL MOISTURE CONTINUE TO SHIFT OVERSPREAD THE AREA AHEAD OF               
THE FRONTAL BOUNDARY. THE STRONGEST Q-VECTORS CONVERGENCE AND                   
ISENTROPIC ASCENT WILL BE OVER THE WESTERN U.P. TEMPTED TO DROP THE             
MENTION OF THUNDERSTORMS FOR THURSDAY AFTERNOON DUE TO THE EXPECTED             
LOW CAPE AND K-INDEX AND HIGH LIFTED INDEX READINGS. HOWEVER...THERE            
STILL DOES APPEAR TO BE SOME 300MB DIVERGENCE...MARGINAL 850-500MB              
LAPSE RATES AND STRONG ENOUGH LOW LEVEL WIND SHEAR TO AT LEAST KEEP             
A MENTION FOR NOW.                                                              
.LONG TERM (THU NIGHT THROUGH NEXT WED)...                                      
THU NIGHT AND FRI...AT 00Z FRI...A NEARLY VERTICALLY STACKED LOW                
SHOULD BE SITUATED IN SW MN...WITH A 990S MB SFC LOW. THE ASSOCIATED            
UPPER TROUGH THE UPPER LOW IS IN LOOKS TO BE NEUTRAL OR POSSIBLY                
EVEN SOMEWHAT NEGATIVELY TILTED...STRETCHING SE INTO ILLINOIS.                  
MAJORITY OF THE MODELS (EXCLUDING THE NAM) PROG THE UPPER LOW TO                
GRADUALLY PUSH EAST DURING THIS PERIOD WHILE THE NEGATIVELY TILTED              
PORTION LIFTS UP INTO UPPER MI. THE 500MB HEIGHT FALLS THU NIGHT ARE            
QUITE IMPRESSIVE...BETWEEN 100-120 DAM. THESE HEIGHT                            
FALLS...COMBINED WITH A STREAM OF 1-1.25 INCH PRECIPITABLE WATER                
VALUES SHOULD BE ENOUGH TO SUPPORT A BAND OF SHOWERS TO MOVE SW TO              
NE ACROSS UPPER MICHIGAN THU NIGHT. WITH CONTINUED GOOD MODEL                   
AGREEMENT ON QPF...RAISED POPS TO CATEGORICAL IN MOST AREAS. DRY                
SLOT COMES IN BEHIND THIS BAND OF SHOWERS...TAPERING OFF THE PCPN.              
STILL MAINTAINED SOME 20 POPS BEHIND THE PCPN...MOSTLY IF THE TIMING            
NEEDS TO BE ADJUSTED WITH LATER RUNS. HOWEVER...IT STILL SEEMS                  
REASONABLE TO ASSUME THAT THE MAJORITY OF PCPN WILL FALL THU NIGHT.             
DID KEEP SOME LOWER CLOUD COVER...BUT DID NOT GO AS LOW AS MIGHT BE             
EXPECTED AS THE SOUNDINGS SUGGEST THE POSSIBILITY OF A LOW CLOUD                
DECK DEVELOPING IN THE WAKE OF THE RAIN (PER NAM/GFS SOUNDINGS).                
SOME WRAP-AROUND SHOWERS...ASSOCIATED WITH THE TROWAL...COULD WRAP              
BACK INTO WESTERN UPPER MICHIGAN ON THE NW SIDE OF THE UPPER                    
LOW...PRIMARILY IN THE AFTERNOON...AND THEREFORE HAVE SOME HIGHER               
POPS THERE. BROUGHT LOW TEMPERATURES UP A BIT CLOSER TO MET GUIDANCE            
GIVEN PLENTY OF CLOUD COVER...RAIN AND HIGH DEWPOINTS. HIGHS ON                 
FRIDAY WERE ALSO RAISED SLIGHTLY GIVEN POSSIBILITY FOR SOME SUN.                
HOWEVER...LATER FORECASTS MAY NEED TO ASSESS THE NEED FOR FOG.                  
FRI NIGHT AND SAT...THE WARM DAYS WE HAVE HAD LOOK LIKE THEY ARE                
GOING TO COME TO AN END...AT LEAST FOR A WHILE. UPPER LOW SHOULD                
CONTINUE TO PUSH EAST DURING THIS PERIOD...REACHING SE ONTARIO BY               
00Z. AS THE UPPER LOW CROSSES INTO WRN LOWER MI BY 12Z SAT...THE

FALL TO -2 TO -4C. OVERALL...PCPN TYPE WILL BE RAIN GIVEN THAT THE              
WET-BULB ZERO HEIGHTS ARE PROGGED TO STAY AT 2000-3000 FT OR EVEN

TEMPS DROPPING TO -4 TO -8C BY 00Z SUN...COOLEST WEST. THE AIR                  
SHOULD BE COLD ENOUGH TO TRANSITION THE PCPN TYPES FROM RAIN TO                 
SNOW. NOT LOOKING FOR MUCH SNOW...THOUGH...DUE TO MOST OF THE                   
VERTICAL MOTION OCCURRING AT TEMPS ABOVE -10C...SFC TEMPS WILL                  
LIKELY BE AT LEAST IN THE MID 30S...AND THE WARM GROUND. ON THE                 
OTHER HAND...ANY SNOW THAT DOES ACCUMULATE SHOULD BE WET GIVEN A                
FAVORABLE PROFILE FOR AGGREGATION. THEREFORE...SNOW TO WATER RATIOS             
ARE EXPECTED AT OR BELOW 10 TO 1. SAT SHOULD BE QUITE BREEZY AS

U.P. AND EAST OF MARQUETTE ARE FAVORED FOR PCPN. AFTER SAT NIGHT...             
THERE MAY NOT BE MUCH PCPN EITHER OVER THE SRN U.P. SINCE THE

FALLS...COMBINED WITH A STREAM OF 1-1.25 INCH PRECIPITABLE WATER

STILL MAINTAINED SOME 20 POPS BEHIND THE PCPN...MOSTLY IF THE TIMING            
NEEDS TO BE ADJUSTED WITH LATER RUNS. HOWEVER...IT STILL SEEMS                  
REASONABLE TO ASSUME THAT THE MAJORITY OF PCPN WILL FALL THU NIGHT.

EXPECTED AS THE SOUNDINGS SUGGEST THE POSSIBILITY OF A LOW CLOUD

BRINGING COLD AIR DOWN FROM CENTRAL CANADA. 850MB TEMPS FROM THE 00Z            
ECMWF DROP TO -10 TO -12C BY 12Z SUN...AND THEN EVEN FALL FURTHER TO            
-12 TO -14C BY 12Z MON THANKS TO ONE OF THE SHRTWVS DROPPING SOUTH              
ON THE WEST SIDE OF THE UPPER TROUGH. READINGS THEN START CLIMBING              
UP MON NIGHT TO -8 TO -10C BY 12Z TUE. OVERALL...THE AIR IS PLENTY              
COLD ENOUGH TO PRODUCE LAKE EFFECT SNOW SHOWERS...AND SINCE THE WIND            
FLOW IS PRIMARILY OUT OF THE NW...THE NW FLOW AREAS OF THE WESTERN              
U.P. AND EAST OF MARQUETTE ARE FAVORED FOR PCPN. AFTER SAT NIGHT...             
THERE MAY NOT BE MUCH PCPN EITHER OVER THE SRN U.P. SINCE THE                   
SHRTWVS DO NOT HAVE MOISTURE TO WORK WITH. THIS MOISTURE                        
AVAILABILITY WILL ALSO AFFECT THE LAKE EFFECT AS WELL...AND GIVEN               
HOW COLD THE AIR IS COMPARED TO THE LAKE SFC...WOULD NOT BE                     
SURPRISED TO SEE SOME HIGHER CLOUD BASES THAN USUAL. THEREFORE...AT             
LEAST RIGHT NOW...NO MAJOR ACCUMULATION IS EXPECTED. HAVE DECIDED TO            
CONTINUE SOME SLIGHT CHANCE POPS INTO TUE MORNING OVER THE EASTERN              
CWA UNTIL ENOUGH DRY AIR AND SUBSIDENCE ASSOCIATED WITH THE HIGH                
COMES IN. TUE SHOULD END UP WARMER AS WELL...BUT STILL ON THE COOL              
SIDE WITH 850MB TEMPS BTWN -6 AND -8C. NO PCPN EXPECTED FOR TUE                 
NIGHT AND WED AS UPPER MI REMAINS UNDER THE INFLUENCE OF DRY AIR

DAKOTA AND EASTERN NEBRASKA. A FRONTAL SYSTEM EXTENDS NORTHEAST FROM            
THE LOW THROUGH NORTHERN MINNESOTA TO JAMES BAY. A STRONG SOUTHERLY

SHORTWAVE ENERGY WILL SHIFT THROUGH MINNESOTA AND WESTERN U.P. THIS

WILL BECOME MORE FOCUSED OVER EASTERN SOUTH DAKOTA THIS AFTERNOON               
BEFORE MOVING EAST INTO NORTHERN IOWA AND SOUTHERN MINNESOTA                    
TONIGHT. A FRONTAL SYSTEM LEADING THIS LOW WILL CONTINUE TO STRETCH             
NORTHEAST BUT WILL START TO SETTLE SOUTH INTO NORTHERN LAKE SUPERIOR            
OVERNIGHT. A TRAILING COLD FRONT WILL BE DRAPED SOUTHWEST INTO                  
MIDDLE AND LOWER MISSISSIPPI RIVER VALLEY. WARM MOIST AIR WILL                  
CONTINUE TO BE LIFTED NORTH AHEAD OF THE FRONTAL SYSTEM. 850-500MB              
Q-VECTOR CONVERGENCE WILL BE CONFINED TO THE WESTERN U.P. THIS                  
AFTERNOON AND TONIGHT. A 45 TO 50 KNOT LOW WILL JET WILL CONTINUE TO            
DRAW MORE MOISTURE INTO THE AREA. AN UPPER LEVEL JET MAX WILL BE                
OVER JAMES BAY AND EASTERN NEBRASKA INTO SOUTHERN MINNESOTA.                    
TOGETHER THESE ARE PRODUCING SOME UPPER LEVEL DIVERGENCE OF THE

993MB IN SE SD THIS AFTN WITH BREEZY SOUTHERLY WINDS CONTINUING

ACCORDING TO DIAGNOSTIC ANALYSIS. THIS LOW PRESSURE WILL GRADUALLY              
WORK INTO SWRN MN OVERNIGHT TONIGHT.                                            
AS UPPER SPEED MAX APPROACHES WITHIN DIFFLUENT MID AND UPPER FLOW               
PATTERN AND LOW LEVEL JET STRENGTHENS...AREAL COVERAGE OF SHOWERS               
SHOULD INCREASE THIS EVENING BEGINNING IN SRN MN. THOUGH SFC CAPE               
UNLIKELY TO BE REALIZED IN OUR FORECAST AREA...ELEVATED INSTABILITY             
FROM THAT REGION WILL ADVECT NORTH NORTHEAST INTO THE FORECAST AREA             
THIS EVE AND EARLY OVERNIGHT. MUCAPE VALUES FROM THE 18Z RUC AND NAM            
RUNS ARE ON THE ORDER OF 200-600 J/KG. SIMILAR ELEVATED CAPE EXISTED            
THIS MORNING...AND A FEW STORMS WERE ABLE TO HAVE VIGOROUS ENOUGH               
UPDRAFTS TO HAVE BRIEF SEVERE HAIL. THUNDERSTORMS IN GENERAL WERE               
FAIRLY PLENTIFUL AND HAVE CONTINUED AT THIS LATITUDE OR NORTH IN                
ADJACENT AREAS TODAY. WHILE THE LAPSE RATES ASSOCIATED WITH THE                 
INSTABILITY TONIGHT ARE NOT PROJECTED TO BE AS STEEP AS THIS                    
MORNING...DEEP LAYER SHEAR VALUES WILL BE LARGE. SO THIS MAY HELP TO            
CREATE A FEW SEVERE STORMS...AND IF SO LIKELY THE LAST FEW OF THE               
YEAR. OVERNIGHT IS LIKELY TO SEE MORE RAIN COVERAGE ESPECIALLY IN               
ERN MN AND WRN WI UNDER TONGUE OF DEEPER OMEGA AND MOISTURE. SREF               
PROBABILITIES INDICATE THE POSSIBILITY OF A HALF INCH IN 6 HOURS OR             
GREATER INCREASING TO ABOVE 50 PERCENT IN SOUTHEAST FORECAST                    
AREA. WITH SOME TRAINING AND HIGH PRECIP EFFICIENCY...A HALF INCH OR            
MORE MAY INDEED BE REALIZED IN SOME COMMUNITIES OVERNIGHT. FLOOD                
THREAT LOOKS MINIMAL THOUGH AS ANY HEAVY RAIN CORES SHOULD BE                   
QUICKLY MOVING. BACK IN WRN MN...AS LOW MOVES OVER THE AREA TONIGHT             
BOTH FOG AND DRIZZLE ARE MORE LIKELY THAN RAIN SHOWERS. AND ONE MORE            
NIGHT OF MIN TEMPS ABOVE AVG MAX TEMPS FOR EARLY NOV.                           
THE BEST ISENTROPIC ASCENT SHIFTS NORTH OF OUR AREA BY THURSDAY

MUCH OF THE SOUTHERN FORECAST AREA. HOWEVER... THERE IS A FAIR                  
AMOUNT OF SPREAD IN THE SREF AND SOME DISAGREEMENT BETWEEN THE NAM              
AND GFS ON THE DEPTH OF MOISTURE WHICH WILL LINGER BENEATH THE DRY              
SLOT. SO... ALTHOUGH THE BEST CHANCE FOR PCPN APPEARS TO BE IN THE              
MORNING HOURS... WILL KEEP POPS GOING THROUGH THE DAY...

WHICH IS REASONABLE GIVEN THE PRIMARY WARM ADVECTION AND                        
FRONTOGENETICAL ZONE TO OUR NORTHWEST... SO THE RAIN/SNOW LINE

FORCING OVER OUR AREA... ALONG THE WESTERN EDGE OF THE PV                       
ANOMALY... LOOKS TO BE OVER THE WEST AND SOUTHWEST... SO SOME

OF THE LONG WAVE TROUGH POISED OVER THE IMMEDIATE LEE OF THE

993MB IN SE SD THIS AFTN WITH BREEZY SOUTHERLY WINDS CONTINUING                 
AHEAD OF THIS. SFC CAPE EXISTS UP TO THE CENTER OF THE LOW                      
ACCORDING TO DIAGNOSTIC ANALYSIS. THIS LOW PRESSURE WILL GRADUALLY              
WORK INTO SWRN MN OVERNIGHT TONIGHT.                                            
AS UPPER SPEED MAX APPROACHES WITHIN DIFFLUENT MID AND UPPER FLOW               
PATTERN AND LOW LEVEL JET STRENGTHENS...AREAL COVERAGE OF SHOWERS               
SHOULD INCREASE THIS EVENING BEGINNING IN SRN MN. THOUGH SFC CAPE               
UNLIKELY TO BE REALIZED IN OUR FORECAST AREA...ELEVATED INSTABILITY             
FROM THAT REGION WILL ADVECT NORTH NORTHEAST INTO THE FORECAST AREA             
THIS EVE AND EARLY OVERNIGHT. MUCAPE VALUES FROM THE 18Z RUC AND NAM            
RUNS ARE ON THE ORDER OF 200-600 J/KG. SIMILAR ELEVATED CAPE EXISTED            
THIS MORNING...AND A FEW STORMS WERE ABLE TO HAVE VIGOROUS ENOUGH               
UPDRAFTS TO HAVE BRIEF SEVERE HAIL. THUNDERSTORMS IN GENERAL WERE               
FAIRLY PLENTIFUL AND HAVE CONTINUED AT THIS LATITUDE OR NORTH IN                
ADJACENT AREAS TODAY. WHILE THE LAPSE RATES ASSOCIATED WITH THE                 
INSTABILITY TONIGHT ARE NOT PROJECTED TO BE AS STEEP AS THIS                    
MORNING...DEEP LAYER SHEAR VALUES WILL BE LARGE. SO THIS MAY HELP TO            
CREATE A FEW SEVERE STORMS...AND IF SO LIKELY THE LAST FEW OF THE               
YEAR. OVERNIGHT IS LIKELY TO SEE MORE RAIN COVERAGE ESPECIALLY IN               
ERN MN AND WRN WI UNDER TONGUE OF DEEPER OMEGA AND MOISTURE. SREF               
PROBABILITIES INDICATE THE POSSIBILITY OF A HALF INCH IN 6 HOURS OR             
GREATER INCREASING TO ABOVE 50 PERCENT IN SOUTHEAST FORECAST                    
AREA. WITH SOME TRAINING AND HIGH PRECIP EFFICIENCY...A HALF INCH OR            
MORE MAY INDEED BE REALIZED IN SOME COMMUNITIES OVERNIGHT. FLOOD                
THREAT LOOKS MINIMAL THOUGH AS ANY HEAVY RAIN CORES SHOULD BE                   
QUICKLY MOVING. BACK IN WRN MN...AS LOW MOVES OVER THE AREA TONIGHT             
BOTH FOG AND DRIZZLE ARE MORE LIKELY THAN RAIN SHOWERS. AND ONE MORE            
NIGHT OF MIN TEMPS ABOVE AVG MAX TEMPS FOR EARLY NOV.                           
THE BEST ISENTROPIC ASCENT SHIFTS NORTH OF OUR AREA BY THURSDAY                 
AFTERNOON... AND IS APPEARS THAT A DECENT DRY SLOT WILL OVERSPREAD              
MUCH OF THE SOUTHERN FORECAST AREA. HOWEVER... THERE IS A FAIR                  
AMOUNT OF SPREAD IN THE SREF AND SOME DISAGREEMENT BETWEEN THE NAM              
AND GFS ON THE DEPTH OF MOISTURE WHICH WILL LINGER BENEATH THE DRY              
SLOT. SO... ALTHOUGH THE BEST CHANCE FOR PCPN APPEARS TO BE IN THE              
MORNING HOURS... WILL KEEP POPS GOING THROUGH THE DAY...

ADJACENT AREAS TODAY. WHILE THE LAPSE RATES ASSOCIATED WITH THE                 
INSTABILITY TONIGHT ARE NOT PROJECTED TO BE AS STEEP AS THIS                    
MORNING...DEEP LAYER SHEAR VALUES WILL BE LARGE. SO THIS MAY HELP TO            
CREATE A FEW SEVERE STORMS...AND IF SO LIKELY THE LAST FEW OF THE               
YEAR. OVERNIGHT IS LIKELY TO SEE MORE RAIN COVERAGE ESPECIALLY IN               
ERN MN AND WRN WI UNDER TONGUE OF DEEPER OMEGA AND MOISTURE. SREF               
PROBABILITIES INDICATE THE POSSIBILITY OF A HALF INCH IN 6 HOURS OR             
GREATER INCREASING TO ABOVE 50 PERCENT IN SOUTHEAST FORECAST                    
AREA. WITH SOME TRAINING AND HIGH PRECIP EFFICIENCY...A HALF INCH OR            
MORE MAY INDEED BE REALIZED IN SOME COMMUNITIES OVERNIGHT. FLOOD                
THREAT LOOKS MINIMAL THOUGH AS ANY HEAVY RAIN CORES SHOULD BE                   
QUICKLY MOVING. BACK IN WRN MN...AS LOW MOVES OVER THE AREA TONIGHT             
BOTH FOG AND DRIZZLE ARE MORE LIKELY THAN RAIN SHOWERS. AND ONE MORE

THE BEST ISENTROPIC ASCENT SHIFTS NORTH OF OUR AREA BY THURSDAY                 
AFTERNOON... AND IS APPEARS THAT A DECENT DRY SLOT WILL OVERSPREAD              
MUCH OF THE SOUTHERN FORECAST AREA. HOWEVER... THERE IS A FAIR                  
AMOUNT OF SPREAD IN THE SREF AND SOME DISAGREEMENT BETWEEN THE NAM              
AND GFS ON THE DEPTH OF MOISTURE WHICH WILL LINGER BENEATH THE DRY              
SLOT. SO... ALTHOUGH THE BEST CHANCE FOR PCPN APPEARS TO BE IN THE              
MORNING HOURS... WILL KEEP POPS GOING THROUGH THE DAY...                        
PARTICULARLY OVER THE NORTH AND WEST.

ADVERTISED THURSDAY NIGHT THROUGH FRIDAY OWING TO THE PRESENCE OF               
THE UPPER LOW. DEEP MOISTURE WILL MOVE BACK INTO THE AREA... WHICH              
WILL COMBINE WITH THE FORCING TO PRODUCE OCCASIONAL LIGHT PCPN.                 
THE TRANSITION FROM RAIN TO SNOW WILL OCCUR FROM SOUTHWEST TO                   
NORTHEAST FROM LATE THURSDAY EVENING THROUGH THE DAY ON FRIDAY...               
WITH PRIMARILY SNOW ANTICIPATED BY FRIDAY NIGHT. FORECAST

WHICH IS REASONABLE GIVEN THE PRIMARY WARM ADVECTION AND                        
FRONTOGENETICAL ZONE TO OUR NORTHWEST... SO THE RAIN/SNOW LINE                  
WILL BE DEPENDENT UPON TEMPERATURES IN THE 1000-850MB LAYER.

FORCING OVER OUR AREA... ALONG THE WESTERN EDGE OF THE PV

ANTICIPATE ANYTHING MORE THAN LIGHT AMOUNTS. TRACE AMOUNTS ARE                  
EXPECTED TO THE NORTH AND EAST. FORCING WILL CONTINUE TO WANE

WITH THAT SAID... HIGH PRESSURE WILL BUILD SOUTH FROM CANADA ON

POSSIBILITY THAT SOME PCPN COULD SNEAK INTO THE SOUTHERN CWFA IF                
THIS SYSTEM WINDS UP FARTHER NORTH... BUT THE TREND HAS BEEN FOR IT

THIS AFTN...LACK OF FOCUS FOR WARM AIR ADVECTION WILL KEEP ANY

BY LATE AFTN AND ESPECIALLY THIS EVENING AS DEEPER LIFT MOVES ATOP              
THE REGION. POTENTIAL FOR THUNDER WILL REMAIN THROUGH MUCH OF

TO THIS MORNING WHEN ALMOST ALL SHOWERS HAD SOME CLOUD-TO-GROUND

THIS FEATURE WILL LIFT UP THE EASTERN SIDE OF THE UPPER TROUGH                  
HELPING IT TO BECOME NEGATIVELY TILTED WHILE THE SURFACE LOW NEAR               
THE SOUTH DAKOTA/NEBRASKA BORDER DEEPENS OVER THE NEXT 24 HOURS

WARM BUT MOISTENING AIR OVER THE REGION. FOR THE FIRST HALF OF                  
THIS AFTN...LACK OF FOCUS FOR WARM AIR ADVECTION WILL KEEP ANY

WE ALSO STRESSED THUNDER BY PUTTING IT AT THE SCATTERED LEVEL

KEPT ALL RAIN ALONG LAKE SUPERIOR AND ACROSS NORTHWEST WISCONSIN

DEEP SURFACE LOW OVER BUFFALO RIDGE IS BRINGING DEW POINTS IN THE               
10C TO 13C RANGE NORTHWARD...ALONG WITH UNSEASONABLY WARM AIR UP                
ACROSS OUR AREA. THE LOW IS XPCD TO STALL OVER BUFFALO RIDGE INTO               
FRIDAY MORNING...AS THE UPPER TROUGH CATCHES UP TO IT AND CUTS                  
OFF. THE UPPER LOW THAT STACKS OVER IT HAS NINE CLOSED CIRCLES                  
WHICH REMOVES IT FROM THE PREVAILING FLOW AND SETS IT UP AS AN                  
OMEGA BLOCK OF ITS VERY OWN. SURFACE PRESSURES FALLING TO AOB 990               
MB WITH THE SORT OF WARM ADVECTION POURING INTO IT SETS IT UP FOR               
THIS BAROCLINIC-TYPE TRANSITIONING AND EVEOLUTION. SO WE LINGER                 
THE WARM AIR OVER US...ALONG WITH THUNDER...RIGHT THROUGH THURSDAY

COOLING REMAINS WEST AND SOUTH OF THIS SYSTEM...AND WEST AND SOUTH              
OF OUR AREA. AGAIN...WE DON/T FEEL THAT THIS SYSTEM IS GOING TO BE              
VERY PROGRESSIVE AT ALL...SO WE AGREE WITH ALL THE MODELS PREFERENCE            
OF LAGGING EASTWARD OR NORTHWARD PROGRESSION OF COLD AIR. WE HOLD               
ANY CHANGE-OVER TO SNOW TO FRIDAY NIGHT...WHICH WILL BE DIFFICULT               
ANYWAY WITH THE WARMTH OF THE GROUND AND ESPECIALLY THE LAKE AND                
ALSO WITH THE LACK OF A TRUE INTRUSION OF ACTUALLY COLD CANADIAN                
AIR. WE DON/T GO TO ALL SNOW ACROSS ALL OF NORTHEAST MN UNTIL                   
SATURDAY AND ACROSS NORTHWEST WISCONSIN UNTIL LATE SATURDAY. PRIND              
THE SYSTEM FINALLY BECOMES PROGRESSIVE ENOUGH TO START PULLING                  
COLD AIR DOWN INTO OUR AREA AFTER THINGS BEGIN TO DRY OUT EARLY

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT. THE MSAS HAS A WEAK LOW           
OVER NORTH CENTRAL LOUISIANA. MODELS SHOW THE DISTURBANCE TRACKING              
ACROSS THE NORTHERN ZONES. THE LINE OF SHOWERS AND OCCASIONAL                   
THUNDERSTORMS WAS STRUGGLING...BUT ISOLATED CELLS WERE STARTING TO              
DEVELOP ALONG AND AHEAD OF THE LINE...WILL MAINTAIN STRONG-SEVERE               
WORDING IN THE HWO. CLOUDS HAVE BEEN SLOW TO MOVE INTO THE                      
SOUTHEAST...MAY STILL BE SOME BREAKS IN THE CLOUDS OVERNIGHT...SO               
LEFT MENTION OF PATCHY FOG IN THE HWO ALSO. THERE WAS ABOUT 25KTS OF            
SOUTHWESTERLY LOW AROUND 850MB. THE LLJ WAS NOT IMPRESSIVE...BUT                
SHOULD BE ENOUGH TO STEER ACTIVITY AND MAINTAIN THUNDERSTORMS THROUGH           
THE EVENING. IT WAS WARMEST ALONG THE RIVER...WITH TVR BEING AROUND             
80. RUC ALSO HAS THE BETTER INSTABILITY ALONG THE RIVER. EXPECTING              
THERE TO BE MOSTLY RAIN AFTER SUNSET WITH THE LOSS OF HEATING. THE              
LINE DID SLOW DOWN TREMENDOUSLY...SO BELIEVE RAIN WILL BE LINGERING             
INTO THE AFTERNOON FOR THE EASTERN ZONES. ADDED SLIGHT CHANCE VALUES            
BACK TO THE METRO AREA ALSO. LATE FRIDAY NIGHT THROUGH SUNDAY...FAIR            
WEATHER RETURNS. IT SHOULD BE CLEAR AND COOL FOR THE WEEKEND.                   
MADE A FEW ADJUSTMENTS TO GUIDANCE TEMPS. LOWERED VALUES SEVERAL                
DEGREES NEARLY EACH DAY OF THE SHORT TERM. LOOKING AT 850 TEMPS AND             
CLIMO...GUIDANCE SEEMED A LITTLE WARM. KEPT POPS FROM PREVIOUS                  
FORECAST...NEW GUIDANCE VALUES WERE NOT DRAMATICALLY DIFFERENT.                 
OVERALL...NO REAL CHANGES TO THE FORECAST.                                      
.LONG TERM...SUNDAY THROUGH THURSDAY.                                           
PREVIOUS DISCUSSION...CONDITIONS WILL BEGIN TO WARM AND SLIGHTLY                
MOISTEN ON MONDAY AS THE UPPER LEVEL PATTERN FLATTENS OUT AND THE LOW           
LEVEL FLOW BECOMES MORE FROM THE SOUTHEAST.                                     
CONFIDENCE IN HOW THE FORECAST WILL PAN OUT REALLY DROPS OFF AFTER              
MONDAY.  BOTH THE GFS AND THE EUROPEAN ARE AT LEAST BRINGING OUR                
NEXT SYSTEM INTO THE FORECAST AREA ON TUESDAY.  HOWEVER...THAT`S                
ABOUT THE ONLY AGREEMENT BETWEEN THE TWO.  THE GFS IS THE MORE                  
PROGRESSIVE OF THE TWO MODELS WITH PUSHING THE SURFACE LOW AND                  
ASSOCIATED COLD FRONT THROUGH THE FORECAST AREA BY TUESDAY NIGHT AND            
ESSENTIALLY DRYING US OUT THROUGH MUCH OF WEDNESDAY.  IT THEN BRINGS            
THE NEXT DISTURBANCE INTO AND THROUGH THE AREA THROUGH THE DAY                  
THURSDAY.                                                                       
THE EUROPEAN ON THE OTHER HAND STALLS THE BOUNDARY ASSOCIATED WITH              
TUESDAY`S SYSTEM OVER THE CWA...THEN DEVELOPS AND SENDS A SERIES OF             
UPPER LEVEL DISTURBANCES THROUGH THE FORECAST WEDNESDAY AND AGAIN               
THURSDAY NIGHT.                                                                 
GIVEN THESE DISCREPANCIES IN THE MODELS DURING THE LATTER HALF OF               
THE FORECAST PERIOD...I`LL STICK CLOSE TO GUIDANCE NUMBERS. /19/

MOISTURE(RUC DEWPOINTS APPEAR TO BE RUNNING TOO LOW AT THE MOMENT)              
AND INSTABILITY WITH POCKETS OF 300-600J/KG MLCAPES FOR NUMEROUS                
SHRA/SCATTERED TSRA TO DEVELOP IN THE PRE-FRONTAL CONVERGENCE ZONE.             
DEWPOINTS WILL APPROACH THE REACH LOWER TO MIDDLE 60S AS DEEPER                 
MOISTURE WILL BE ON THE INCREASE BY MID AFTERNOON WITH PWATS NEAR               
1.7 INCHES. THE BULK OF THE FRONTAL FORCING REMAINS TO OUR NW AND N             
DURING THE DAYLIGHT AND WIND FIELDS BECOME MORE UNIDIRECTIONAL THE              
LATER IN THE DAY WE GET.  THE RISK FOR SEVERE WEATHER STILL REMAINS             
IN THE SLIGHT CATEGORY OR LOWER AND CONFINED TO THE NWRN THIRD OF               
THE CWFA AS LACKING INSTABILITY AND THE NIGHT TIME FRONTAL PASSAGE              
SEEMS TO KEEP THIS SYSTEM IN CHECK. WILL KEEP MENTION IN THE HWOJAN             
OF A FEW STRONG AND POSSIBLY A SVR STORM OR TWO JUST AHEAD OF THE               
FRONT. THE BEST TIMING FOR THIS WILL BE FROM ABOUT 20Z-02Z ACROSS               
THE NWRN PORTIONS.                                                              
BY TONIGHT...THE SLOWING FRONT AND DIMINSHING INSTABILITY SHOULD                
YIELD A BAND OF SHRA/ISOLATED TSRA STEADILY CROSSING THE AREA FROM              
NW TO SE. THE MAIN AXIS OF PRECIPITATION SHOULD LIE ALONG THE                   
NATCHEZ TRACE CORRIDOR BY ABOUT MIDNIGHT AND SHIFT TO THE SERN                  
COUNTIES CLOSE TO DAYBREAK. QPF AMOUNTS OF ONE HALF TO ONE INCH                 
APPEAR TO BE MOST LIKELY WITH THIS SYSTEM AS THE FRONT REACHES NEAR             
A MERIDIAN-BROOKHAVEN ARE BY 18Z FRIDAY. EXPECT BROKEN AREA OF                  
SHRA/TSRA EARLY FRIDAY AFTERNOON OVER SERN MS WHILE CLEARING RETURNS            
TO THE DELTA REGION. RATHER WEAK CAA SHOULD PUT MOST HIGHS FRIDAY IN            
THE 65-70F RANGE. /40/                                                          
FRIDAY NIGHT THROUGH NEXT THURSDAY...THE COLD FRONT WILL CONTINUE TO            
EXIT THE FORECAST AREA TO THE EAST FRIDAY NIGHT. SOME LIGHT SHOWER              
ACTIVITY COULD HOLD ON ACROSS EAST AND SOUTHEAST MISSISSIPPI EARLY IN           
THE PERIOD...BUT BY MIDNIGHT ALL OF THE RAIN SHOULD BE OFF TO THE               
EAST AND OUT OF THE AREA.                                                       
MEANWHILE...AS THE FRONT EXITS STAGE EAST...A COOLER DRIER AIRMASS              
WILL BEGIN TO FILTER INTO THE FORECAST AREA AS HIGH PRESSURE TO THE             
NORTHWEST BUILDS SOUTHEAST INTO THE LOWER MISSISSIPPI RIVER VALLEY.             
THIS WILL IN TURN PROVIDE US WITH VERY PLEASANT AUTUMN CONDITIONS               
THROUGHOUT THE UPCOMING WEEKEND.  CONDITIONS WILL THEN BEGIN TO WARM            
AND SLIGHTLY MOISTEN ON MONDAY AS THE UPPER LEVEL PATTERN FLATTENS              
OUT AND THE LOW LEVEL FLOW BECOMES MORE FROM THE SOUTHEAST.                     
CONFIDENCE IN HOW THE FORECAST WILL PAN OUT REALLY DROPS OFF AFTER              
MONDAY.  BOTH THE GFS AND THE EUROPEAN ARE AT LEAST BRINGING OUR                
NEXT SYSTEM INTO THE FORECAST AREA ON TUESDAY.  HOWEVER...THAT`S                
ABOUT THE ONLY AGREEMENT BETWEEN THE TWO.  THE GFS IS THE MORE                  
PROGRESSIVE OF THE TWO MODELS WITH PUSHING THE SURFACE LOW AND                  
ASSOCIATED COLD FRONT THROUGH THE FORECAST AREA BY TUESDAY NIGHT AND            
ESSENTIALLY DRYING US OUT THROUGH MUCH OF WEDNESDAY.  IT THEN BRINGS            
THE NEXT DISTURBANCE INTO AND THROUGH THE AREA THROUGH THE DAY                  
THURSDAY.                                                                       
THE EUROPEAN ON THE OTHER HAND STALLS THE BOUNDARY ASSOCIATED WITH              
TUESDAY`S SYSTEM OVER THE CWA...THEN DEVELOPS AND SENDS A SERIES OF             
UPPER LEVEL DISTURBANCES THROUGH THE FORECAST WEDNESDAY AND AGAIN               
THURSDAY NIGHT.

TIMING OF THE ONSET OF LOW CEILINGS IS SOMEWHAT LOW...AN OVERCAST               
DECK BETWEEN 1K AND 3K FT SHOULD PREVAIL THROUGH MUCH OF THURSDAY

LATER INTO THE EVENING...BUT WILL DEFER TO LATER FORECASTS TO                   
REFINE THIS MATTER. ONE CERTAINTY IS THAT STRONG WEST/NORTHWEST

NOT LOOK LIKE VERY MUCH PRECIPITATION AND SNOW AMOUNTS WILL BE                  
LOW. MODELS WERE A BIT ALARMING FROM 06Z RUNS IN REGARD TO                      
POSSIBLE WIND SPEEDS...BUT 12Z RUNS HAVE SHOWN ABOUT A 10 KT                    
REDUCTION...FITTING MORE COMFORTABLY INTO A WIND ADVISORY SCENARIO              
FOR THURSDAY/THURSDAY NIGHT...INSTEAD OF A HIGH WIND WATCH.                     
FOR PRECIPITATION CHANCES...LOOKS SIMILAR TO THE PREVIOUS                       
FORECAST...BUT DID EXTEND LOW CHANCES A BIT FARTHER TO THE SOUTH.               
RE0RIENTED THE SNOW GRIDS A TAD. LOWERED TEMPERATURES A BIT MORE                
FOR THURSDAY HIGHS. HIGHS WILL NOT GO ANYWHERE ON THURSDAY WITH                 
STRONG COLD AIR ADVECTION AND PLENTY OF SKY COVER. MAY BE                       
TEMPORARY BOUTS OF REDUCED VISIBILITY WITH SCATTERED SNOW SHOWERS               
THURSDAY AND THURSDAY NIGHT...BUT FOR NOW IT DOES NOT LOOK LIKE IT              
WILL BE ENOUGH OF A FACTOR TO INTRODUCE A WINTER WEATHER PRODUCT                
AT THIS TIME. THE MAIN HAZARD WILL BE THE WIND FROM THE NORTHWEST.              
COULD BE A BIT STRONG EXTENDING INTO FRIDAY MORNING...BUT WE CAN                
VISIT THIS LATER AS WE BECOME MORE CONFIDENT. I TENDED TO LIKE THE              
RUC FOR THIS EVENING...THEN LEAN MORE TOWARD A NAM SCENARIO FOR

UPPER LOW PRESSURE SYSTEM WILL BE LOCATED NEAR THE MINNESOTA AND                
IOWA BORDER ON FRIDAY MORNING.  MODELS DIFFER ON WHETHER OR NOT                 
WRAPAROUND SNOW SHOWERS OR FLURRIES WILL CONTINUE FRIDAY MORNING                
WITH THE GFS MORE ROBUST WITH THIS THAN THE NAM...BUT HAVE CONTINUED            
TO MENTION THE POTENTIAL IN OUR NORTHEAST CWA FOR THE MORNING.                  
LITTLE IF ANY SNOW ACCUMULATION IS EXPECTED FRIDAY MORNING.   WINDS             
WILL STILL REMAIN STRONG FROM THE NORTHWEST THROUGH AT LEAST THE                
FIRST HALF OF THE DAY IN A STILL TIGHT SURFACE GRADIENT...UNTIL THE             
SYSTEM LIFTS FARTHER TO THE NORTHEAST AND THE GRADIENT RELAXES.                 
HIGH PRESSURE BUILDS IN BEHIND THE FRONT ON SATURDAY AND A COOL                 
AIRMASS REMAINS IN PLACE.  MODELS DIVERGE OVER THE WEEKEND AND INTO             
NEXT WEEK WITH THE NEXT COUPLE OF SYSTEMS.  THE GFS BACKS IN COLDER             
AIR AND DEVELOPS A FRONTOGENETIC BAND OF PRECIPITATION POSSIBLY                 
BEGINNING AS EARLY AS SATURDAY NIGHT...BUT MORE SO INTO THE SUNDAY              
PERIOD.  THE GFS TEMPERATURE PROFILE IS MUCH COOLER THAN THE ECMWF              
AND SUGGESTS POTENTIAL FOR SOME SNOW.  THE 00Z ECMWF DEVELOPS THE               
PCPN SATURDAY NIGHT TO OUR WEST IN THE HIGH PLAINS IN THE UPSLOPE               
FLOW CONDITIONS...WITH AN OVERALL WARMER/LIQUID TEMPERATURE                     
PROFILE.  THE GEM ALSO SUGGESTS THE POTENTIAL FOR PCPN ON SUNDAY AND            
FEEL BEST BET IS TO MAINTAIN THE STATUS QUO OF LOW POPS FOR NOW                 
UNTIL MODELS COME INTO MORE AGREEMENT.  AND NOW...THE 12Z ECMWF                 
SOLUTION HAS COME AROUND TO MORE OF THE GFS/GEM SOLUTIONS...BUT                 
HOLDS ONTO A WARMER TEMP PROFILE.                                               
ON MONDAY OF NEXT WEEK...A CLOSED LOW PRESSURE SYSTEM IS PROGGED TO             
MOVE EAST ALONG THE SOUTHERN TIER STATES AND LIFT ACROSS OKLAHOMA               
AND KANSAS THRU MONDAY NIGHT.  THE ECMWF FAVORS A STRONGER SOLUTION             
VS THE GFS WHICH FILLS THE SYSTEM AS IT MOVES INTO THE PLAINS.  THE             
GFS IS ALSO COLDER WITH ITS TEMP PROFILE SUGGESTING THE POTENTIAL               
FOR MIXED PCPN OR SNOW...WHEREAS THE ECMWF SUGGESTS MORE OF A                   
RAINFALL EVENT.  HAVE MAINTAINED POPS FOR MONDAY AND MONDAY NIGHT               
WITH THE INCREASING ISENTROPIC LIFT AND POTENTIAL FOR DEFORMATION               
PCPN.  HAVE KEPT PCPN AS RAIN INITIALLY WITH A R/S MIX AS TEMPS COOL            
ON THE BACK SIDE OF THE SYSTEM MONDAY NIGHT.  THE 12Z ECMWF NOW HAS             
A MORE SOUTHERN TRACK THAN ITS PREVIOUS RUN WHICH SUGGESTS EVEN                 
LESSER OF A CHC FOR PCPN IN OUR CWA...BUT WILL NEED TO WATCH.

DISCUSSION...DEFINITELY NOT A QUIET FORECAST FOR THE SHORT TERM                 
PERIOD THROUGH FRIDAY...AS PRECIPITATION CHANCES MAKE A RETURN.                 
THIS IS CAUSED BY AN UPPER LEVEL TROUGH/LOW PRESSURE                            
SYSTEM...WHICH 00Z UPPER AIR OBSERVATION DATA AND CURRENT                       
SATELLITE IMAGERY SHOW OVER THE ROCKIES. AHEAD OF THIS TROUGH AT                
THE SURFACE...CURRENT ANALYSIS SHOWS LOW PRESSURE/TROUGH DRAPED                 
ACROSS THE HIGH PLAINS. AS EXPECTED...A FEW SHOWERS HAVE DEVELOPED              
IN ASSOCIATION WITH 40-55KT SOUTHERLY LOW LEVEL NOSING INTO THE                 
AREA...AND HAVE STAYED TO THE NORTH/EAST OF THE CWA.                            
LITTLE HAS CHANGED LOOKING INTO THE REST OF TODAY...AND MODELS ARE              
IN MUCH BETTER AGREEMENT THAN A FEW DAYS AGO.  AS THE DAYTIME HOURS             
PASS...THE MAIN UPPER LEVEL SYSTEM BECOMES BETTER ORGANIZED AS IT               
SHIFTS EAST...AND BY THIS EVENING IS CENTERED OVER THE PANHANDLE OF             
NEBRASKA.  MEANWHILE AT THE SURFACE...THE AREA OF LOW PRESSURE GETS             
PUSHED EAST ACROSS THE CWA...ALONG WITH ITS ACCOMPANYING COLD                   
FRONT. AHEAD OF THIS FRONT...WHILE STILL BREEZY...SOUTHERLY WINDS               
EXPECTED TO STAY IN THE 15 TO 25 MPH RANGE. WITH THE FRONT PASSING              
THROUGH DURING THE AFTERNOON HOURS...THIS LEAVES A GRADIENT WITH                
HIGH TEMPERATURES ACROSS THE CWA...WITH WESTERN AREAS EXPECTED TO               
PEAK IN THE LOWER 60S...AND AREAS AHEAD OF THE FRONT IN THE EAST                
IN THE LOWER 70S. THE FRONT IS ALSO THE FOCUS FOR THUNDERSTORM                  
DEVELOPMENT THIS AFTERNOON AND EVENING...BUT UNCERTAINTIES REMAIN               
AS TO JUST HOW MUCH OF OUR CWA ACTUALLY SEES ANY ACTION. MODEL                  
CONTINUE TO BE IN GOOD AGREEMENT SHOWING THE FRONT AT 00Z TONIGHT               
RIGHT ON THE EASTERN BORDER OF THE CWA. UPPED POPS A BIT...BUT                  
DIDN/T EXPAND VERY FAR WEST...MAINLY AREAS EAST OF HIGHWAY 281.                 
THERE CONTINUES TO BE THE POSSIBILITY THAT SOME THUNDERSTORMS MAY               
BECOME STRONG/SEVERE...AS MODELS SHOW GOOD SHEAR AND INSTABILITY                
NEAR 1000 J/KG. DURING THE EVENING HOURS...TAPERED BACK POPS A BIT              
AS ANYTHING THAT DEVELOPS IS EXPECTED TO QUICKLY MOVE OFF TO THE                
EAST.                                                                           
LOOKING TO OVERNIGHT TONIGHT THROUGH THURSDAY...ANY CHANCES OF                  
PRECIPITATION THE CWA SEES WILL COME WITH ANY LINGERING                         
SHOWERS/THUNDER EARLY ON...WITH THE SOURCE LATER TONIGHT AND INTO               
THURSDAY BEING WITH MOISTURE WRAPPING AROUND THE BACKSIDE OF THE LOW            
PRESSURE SYSTEM.  MODELS IN GOOD AGREEMENT WITH THE PATH OF THE                 
LOW...WHICH CROSSES THROUGH NORTHERN NEBRASKA.  THIS PATH LIMITS THE            
AREAL EXTENT OF PRECIPITATION IN OUR CWA...WITH CHANCES DROPPING                
SIGNIFICANTLY HEADING SOUTH OF INTERSTATE 80. FELT INHERITED POPS               
HAD A GOOD HANDLE ON THE PROGRESSION AND ONLY MINOR ADJUSTMENTS WERE            
MADE.  AS THE SYSTEM MOVES EAST...ALONG WITH MOISTURE GETTING PULLED            
SOUTH INTO THE CWA...SO DOES COLDER AIR.  EVEN STARTING LATER                   
TONIGHT/EARLY THURSDAY MORNING...NORTHERN AREAS COULD SEE A                     
RAIN/SNOW MIX...WHICH WILL EXPAND A BIT FURTHER SOUTH DURING THE DAY            
AS MORE COLD ARE BUILDS IN.  NOT EXPECTING SIGNIFICANT                          
ACCUMULATIONS...AS BEST MOISTURE/FORCING REMAINS TO THE NORTH...BUT             
A DUSTING TO NEAR A HALF INCH IS POSSIBLE ACROSS NORTHERN AREAS.                
BIG CONCERN FOR THURSDAY LIES WITH WINDS.  AS THE STORM SYSTEM                  
SHIFTS EAST...NORTHWESTERLY WINDS ON THE BACKSIDE GET CRANKED UP AS             
THE PRESSURE GRADIENT TIGHTENS UP AND MIXING IMPROVES.  HIGHEST                 
WINDS LOOK TO REMAIN TO OUR WEST...BUT THERE LOOKS TO BE A GOOD                 
CHANCE FOR SOLID ADV LEVEL WINDS...WITH GUSTS NEAR 50 MPH NOT OUT OF            
THE QUESTION. WITH THIS BEING IN THE THIRD PERIOD AND WITH                      
AGREEMENT AMONG SURROUNDING OFFICES...WILL CONTINUE MENTION IN                  
HWO AND LET DAY SHIFT GET ANOTHER MODEL RUN TO LOOK AT TO NAIL                  
DOWN THE EXACT LOCATION/TIME. WITH THE STRONG WINDS...AND                       
POSSIBILITY OF LIGHT SNOW...COULD CAUSE REDUCED VISIBILITIES IN                 
THE NORTH. SNOW DOESN/T LOOK TO BE HEAVY ENOUGH AT THIS TIME TO                 
CAUSE SIGNIFICANT PROBLEMS...BUT THE AREA WILL BE CLOSELY WATCHED.              
THINGS START TO REALLY WIND DOWN THURSDAY NIGHT...WITH

SHOULD REACH ADVISORY LEVEL DURING THE MORNING OUT OF THE WEST                  
NORTHWEST.                                                                      
PREV DISCUSSION... /ISSUED 412 AM CST WED NOV 5 2008/                           
DISCUSSION...DEFINITELY NOT A QUIET FORECAST FOR THE SHORT TERM                 
PERIOD THROUGH FRIDAY...AS PRECIPITATION CHANCES MAKE A RETURN.                 
THIS IS CAUSED BY AN UPPER LEVEL TROUGH/LOW PRESSURE                            
SYSTEM...WHICH 00Z UPPER AIR OBSERVATION DATA AND CURRENT                       
SATELLITE IMAGERY SHOW OVER THE ROCKIES. AHEAD OF THIS TROUGH AT                
THE SURFACE...CURRENT ANALYSIS SHOWS LOW PRESSURE/TROUGH DRAPED                 
ACROSS THE HIGH PLAINS. AS EXPECTED...A FEW SHOWERS HAVE DEVELOPED              
IN ASSOCIATION WITH 40-55KT SOUTHERLY LOW LEVEL NOSING INTO THE                 
AREA...AND HAVE STAYED TO THE NORTH/EAST OF THE CWA.                            
LITTLE HAS CHANGED LOOKING INTO THE REST OF TODAY...AND MODELS ARE              
IN MUCH BETTER AGREEMENT THAN A FEW DAYS AGO.  AS THE DAYTIME HOURS             
PASS...THE MAIN UPPER LEVEL SYSTEM BECOMES BETTER ORGANIZED AS IT               
SHIFTS EAST...AND BY THIS EVENING IS CENTERED OVER THE PANHANDLE OF             
NEBRASKA.  MEANWHILE AT THE SURFACE...THE AREA OF LOW PRESSURE GETS             
PUSHED EAST ACROSS THE CWA...ALONG WITH ITS ACCOMPANYING COLD                   
FRONT. AHEAD OF THIS FRONT...WHILE STILL BREEZY...SOUTHERLY WINDS               
EXPECTED TO STAY IN THE 15 TO 25 MPH RANGE. WITH THE FRONT PASSING              
THROUGH DURING THE AFTERNOON HOURS...THIS LEAVES A GRADIENT WITH                
HIGH TEMPERATURES ACROSS THE CWA...WITH WESTERN AREAS EXPECTED TO               
PEAK IN THE LOWER 60S...AND AREAS AHEAD OF THE FRONT IN THE EAST                
IN THE LOWER 70S. THE FRONT IS ALSO THE FOCUS FOR THUNDERSTORM                  
DEVELOPMENT THIS AFTERNOON AND EVENING...BUT UNCERTAINTIES REMAIN               
AS TO JUST HOW MUCH OF OUR CWA ACTUALLY SEES ANY ACTION. MODEL                  
CONTINUE TO BE IN GOOD AGREEMENT SHOWING THE FRONT AT 00Z TONIGHT               
RIGHT ON THE EASTERN BORDER OF THE CWA. UPPED POPS A BIT...BUT                  
DIDN/T EXPAND VERY FAR WEST...MAINLY AREAS EAST OF HIGHWAY 281.                 
THERE CONTINUES TO BE THE POSSIBILITY THAT SOME THUNDERSTORMS MAY               
BECOME STRONG/SEVERE...AS MODELS SHOW GOOD SHEAR AND INSTABILITY                
NEAR 1000 J/KG. DURING THE EVENING HOURS...TAPERED BACK POPS A BIT              
AS ANYTHING THAT DEVELOPS IS EXPECTED TO QUICKLY MOVE OFF TO THE                
EAST.                                                                           
LOOKING TO OVERNIGHT TONIGHT THROUGH THURSDAY...ANY CHANCES OF                  
PRECIPITATION THE CWA SEES WILL COME WITH ANY LINGERING                         
SHOWERS/THUNDER EARLY ON...WITH THE SOURCE LATER TONIGHT AND INTO               
THURSDAY BEING WITH MOISTURE WRAPPING AROUND THE BACKSIDE OF THE LOW            
PRESSURE SYSTEM.  MODELS IN GOOD AGREEMENT WITH THE PATH OF THE                 
LOW...WHICH CROSSES THROUGH NORTHERN NEBRASKA.  THIS PATH LIMITS THE            
AREAL EXTENT OF PRECIPITATION IN OUR CWA...WITH CHANCES DROPPING                
SIGNIFICANTLY HEADING SOUTH OF INTERSTATE 80. FELT INHERITED POPS               
HAD A GOOD HANDLE ON THE PROGRESSION AND ONLY MINOR ADJUSTMENTS WERE            
MADE.  AS THE SYSTEM MOVES EAST...ALONG WITH MOISTURE GETTING PULLED            
SOUTH INTO THE CWA...SO DOES COLDER AIR.  EVEN STARTING LATER                   
TONIGHT/EARLY THURSDAY MORNING...NORTHERN AREAS COULD SEE A                     
RAIN/SNOW MIX...WHICH WILL EXPAND A BIT FURTHER SOUTH DURING THE DAY            
AS MORE COLD ARE BUILDS IN.  NOT EXPECTING SIGNIFICANT                          
ACCUMULATIONS...AS BEST MOISTURE/FORCING REMAINS TO THE NORTH...BUT             
A DUSTING TO NEAR A HALF INCH IS POSSIBLE ACROSS NORTHERN AREAS.                
BIG CONCERN FOR THURSDAY LIES WITH WINDS.  AS THE STORM SYSTEM                  
SHIFTS EAST...NORTHWESTERLY WINDS ON THE BACKSIDE GET CRANKED UP AS             
THE PRESSURE GRADIENT TIGHTENS UP AND MIXING IMPROVES.  HIGHEST                 
WINDS LOOK TO REMAIN TO OUR WEST...BUT THERE LOOKS TO BE A GOOD                 
CHANCE FOR SOLID ADV LEVEL WINDS...WITH GUSTS NEAR 50 MPH NOT OUT OF            
THE QUESTION. WITH THIS BEING IN THE THIRD PERIOD AND WITH                      
AGREEMENT AMONG SURROUNDING OFFICES...WILL CONTINUE MENTION IN                  
HWO AND LET DAY SHIFT GET ANOTHER MODEL RUN TO LOOK AT TO NAIL                  
DOWN THE EXACT LOCATION/TIME. WITH THE STRONG WINDS...AND                       
POSSIBILITY OF LIGHT SNOW...COULD CAUSE REDUCED VISIBILITIES IN                 
THE NORTH. SNOW DOESN/T LOOK TO BE HEAVY ENOUGH AT THIS TIME TO                 
CAUSE SIGNIFICANT PROBLEMS...BUT THE AREA WILL BE CLOSELY WATCHED.              
THINGS START TO REALLY WIND DOWN THURSDAY NIGHT...WITH                          
LITTLE/NOTHING EXPECTED BY FRIDAY MORNING...WITH THE REST OF                    
FRIDAY AND INTO THE FIRST PART OF THE WEEKEND REMAINING DRY. AS

TOWARD THE OH VALLEY. CLOSER TO HOME...WEAK DOWNSLOPE FLOW WILL

THE GFS IS MORE BULLISH IN DEVELOPING AN AREA OF RAIN ACROSS THE

BECOME CALM IN PLACES AND AS A RESULT FOG HAS DEVELOPED AND HAS                 
BECOME BRIEFLY DENSE AT TIMES. THIS WILL BE AN ISSUE AT THESE                   
TERMINALS THROUGH SUNRISE WITH IFR/LIFR VISIBILITIES LIKELY TO                  
OCCUR...ALTHOUGH 15-20 KT WINDS JUST 1000 FT UP SHOULD KEEP                     
VISIBILITIES JUMPING UP AND DOWN THROUGH THE NIGHT. DUE TO STRONGER             
WIND SPEEDS IN THE BOUNDARY LAYER FOG DEVELOPMENT IS LESS LIKELY AT             
THE COASTAL TERMINALS...EXCEPT AT CRE WHERE LOCAL EFFECTS WILL ALLOW

THE SEAS HAVE BEEN ALSO BEEN TWEAKED A FOOT OR 2 HIER...MAINLY

THE GFS IS MORE BULLISH IN DEVELOPING AN AREA OF RAIN ACROSS THE

.DISCUSSION...NO MAJOR UPDATED NEEDED AT THIS POINT. PREVIOUS                   
FORECAST THINKING REMAINS VALID (SEE BELOW). ALL CURRENT HEADLINES              
ON TRACK. CURRENT RAIN AREA LOCATED ALONG AND NORTH OF A                        
COOPERSTOWN-GRAND FORKS-ROSEAU LINE (STRONGEST 850MB WARM AIR                   
ADVECTION). THIS AREA OF RAIN WILL REMAIN MAINLY ACROSS THE DVL                 
BASIN THROUGH 12Z THUR. SE FA WILL PROBABLY BE MAINLY DRY DURING                
THIS TIME (CURRENT FORECAST DOES SHOW LOWER POPS ACROSS THIS                    
AREA). LEADING EDGE OF NEXT SLUG OF MOISTURE SEEN ON RADAR IMAGERY              
ACROSS IOWA/S MN. THIS WILL PROPAGATE INTO THE FA TOMORROW                      
MORNING. THINK CURRENT QPF FORECAST ON TRACK GIVEN THE ABOVE.                   
BIGGEST QUESTION MARK WITH THIS EVENT LOOKS TO BE                               
P-TYPE...ESPECIALLY ACROSS THE DVL BASIN TONIGHT INTO THURSDAY.

STRONGER/NW WITH SFC LOW INDICATING CHANGEOVER TO SNOW WILL BE                  
DELAYED. WILL AWAIT ALL 00Z GUIDANCE AND ALLOW MID-SHIFT TO ASSESS

APPROACHES ON FRIDAY A COLD FRONT WILL BE PUSHED ACROSS THE                     
REGION. A SECONDARY SURGE OF COLDER AIR WILL ARRIVE ON SATURDAY

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...                                       
MOSTLY COSMETIC CHANGES TO CURRENT FORECAST/GRAPHICS. WILL TRY TO               
TIME THE ONSET OF SHOWERS A LITTLE BETTER. USING EXTRAPOLATION THE              
SHOWERS WOULD REACH THE TOLEDO AREA ABOUT 3 AM BUT MORE LIKELY                  
6 AM BASED ON THE LATEST RUC AND OTHER MODELS. ALL MODELS                       
INDICATE THAT THE OCCLUDED FRONT WILL CONTINUE TO WEAKEN AND THE                
SHOWERS WILL ALSO WEAKEN FRI MORN. SHOWERS WILL THEN PUSH EAST AND              
WEAK WAVE TO DEVELOP ON THE FRONT AND SHOWERS WILL REDEVELOP                    
ACROSS NE OH/NW PA.                                                             
UPPER LEVEL LOW CONTINUES TO SPIN OVER THE NORTHERN PLAINS STATES               
AND IS PUSHING A COLD FRONT SLOWLY CLOSER TO WESTERN OHIO. A FEW                
SHOWERS/THUNDERSTORMS HAVE DEVELOPED ALONG THIS BOUNDARY OVER                   
ILLINOIS AND WESTERN INDIANA. THESE SHOWERS MAY MOVE INTO WESTERN               
OHIO AFTER MIDNIGHT. CLOUD COVER WILL GRADUALLY INCREASE THROUGH                
THE EVENING...ESPECIALLY OUT WEST. THESE CLOUDS SHOULD KEEP THE                 
WESTERN AREAS WARMER THAN THE LAST COUPLE OF NIGHTS. BELIEVE THAT               
IT WILL STILL RADIATE WELL OUT EAST WHERE SKIES WILL REMAIN CLEAR               
THE LONGEST. THIS WILL SET UP A DECENT GRADIENT IN TEMPERATURES                 
FROM WEST TO EAST OVERNIGHT WITH LOWS NEAR 50 OUT WEST AND INTO                 
THE UPPER 30S FOR THE INLAND VALLEYS.

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY NIGHT/...                       
FRONT SHOULD BE MOVING ACROSS NORTHERN OHIO ON FRIDAY AND INTO                  
NORTHWESTERN PA FOR FRIDAY EVENING. MADE VERY FEW CHANGES TO THE                
CHANCES OF THE SHOWERS AND THUNDERSTORMS ALONG THE FRONT. HOWEVER               
AM GROWING MORE CONCERNED THAT THE LINE OF SHOWERS/THUNDERSTORMS                
THAT DEVELOPS MAY END UP BEING A SCATTERED LINE THAT MOVES                      
EASTWARD ACROSS THE CWA AS THE DRY SLOT SURGES ACROSS NORTHERN                  
OHIO. THIS MAY LEAD TO SOME DECENT BREAKS AND SOME BREEZY                       
CONDITIONS ACROSS NORTHWESTERN OHIO. LATER SHIFTS WILL NEED TO                  
MONITOR THIS HIGHER WIND POSSIBILITY. TEMPERATURES WILL BE COOLER               
ON FRIDAY WITH THE ADDED CLOUD COVER BUT SHOULD STILL REMAIN A                  
GOOD 10 TO 15 DEGREES ABOVE AVERAGE.                                            
A SECONDARY SURGE OF COLD ARI WILL SPILL INTO THE AREA ON SATURDAY              
AS THE UPPER LEVEL LOW MOVES INTO SOUTHERN ONTARIO. WILL KEEP                   
CHANCE POPS IN THE FORECAST THROUGH THE WEEKEND WITH THE UPPER                  
LEVEL LOW IN THE VICINITY. BEST RAIN CHANCES WILL BE THE SNOWBELT               
AREAS ACROSS NORTHEAST OHIO AND NORTHWEST PA. TEMPERATURES MAY BE               
COLD ENOUGH FOR A FEW SNOWFLAKES SATURDAY NIGHT. BETTER CHANCES OF              
SNOW ARRIVE BY SUNDAY NIGHT AS THE ENTIRE COLUMN COOLS.                         
EXPECT MUCH COOLER CONDITIONS FOR SATURDAY AND SUNDAY WITH HIGHS                
BACK INTO THE 40S.

.LONG TERM /MONDAY THROUGH THURSDAY/...                                         
NOT TOO MANY CHANGES TO THE EXTENDED FORECAST TODAY WITH LITTLE                 
CHANGE NOTED IN THE LONG RANGE GUIDANCE. CYCLONIC FLOW WILL BE                  
UNDERWAY MONDAY MORNING AND I CONTINUED WITH A RAIN/SNOW MIX IN THE             
SNOWBELT COUNTIES. BY MONDAY NIGHT HOWEVER WEAK RIDGING AT THE                  
SURFACE AND ALOFT SHOULD ACT TO DRY OUT ANY LINGERING RAIN/SNOW                 
SHOWERS AND I DRIED THINGS OUT BY TUESDAY MORNING.                              
SOME MODEL DISCREPANCIES CONTINUE TO REVEAL THEMSELVES FROM TUESDAY             
AND BEYOND. THE GFS AND GEM MODELS ARE QUITE FAST BRINGING PRECIP UP            
THE OHIO VALLEY ON TUESDAY WHILE THE EURO IS A BIT MORE                         
CONSERVATIVE. THE NEW EURO IS STARTING TO LOOK MORE AND MORE LIKE               
THE GFS/GEM SO I DECIDED TO SPLIT THE DIFFERENCE AND BRING RAIN INTO            
THE SOUTHERN HALF OF THE FORECAST AREA TUESDAY AFTERNOON. THE PERIOD            
FROM TUESDAY NIGHT THROUGH THURSDAY LOOKS TO BE QUITE ACTIVE AS ONE             
WAVE MOVES SOUTH OF THE AREA WEDNESDAY...FOLLOWED BY BRIEF HIGH                 
PRESSURE WEDNESDAY NIGHT AND ANOTHER SOUTHERN STREAM LOW ON                     
THURSDAY. LOW CHANCE POPS IN EACH PERIOD LOOKS REASONABLE...HARD TO

.AVIATION /03Z FRIDAY THROUGH TUESDAY/...                                       
THE FIRST HALF OF THE TAF PERIOD WILL BE QUIET BUT PRECIP CHANCES               
WILL INCREASE FRI AM. COLD FRONT STILL ON TRACK TO MOVE INTO NW PA              
TOWARD END OF TAF PERIOD. CURRENTLY A BAND OF SHRA/TSRA OVER                    
INDIANA. THIS BAND WILL CONTINUE TO MAKE ONLY VERY SLOW PROGRESS E              
OVERNIGHT WHILE ALSO SLOWLY DISSIPATING. WILL START PRECIP AS                   
EARLY AS 09Z AT KTOL BUT PRECIP SHOULD BE VERY LIGHT. BETTER                    
CHANCES FOR PRECIP WILL COME FRI AFTERNOON AS FRONT MOVES THROUGH.              
LOCATIONS E OF I-71 CORRIDOR WILL SEE GOOD CHANCES FOR CONVECTION               
FRI AFTERNOON. THUNDER WILL BE A POSSIBILITY BUT FOR NOW WILL ONLY              
MENTION CB IN TAFS. HEAVIER SHOWERS COULD DROP VSBYS AND CIGS TO                
MVFR. LOCATIONS BEHIND FRONT WILL BE DRY SLOTTED AND EXPECT KTOL                
AND KFDY TO BE DRY ONCE INITIAL BAND OF SHOWERS MOVES THROUGH LATE TONIGHT.     
LIGHT SE TO S FLOW WILL BECOME SW AND GUSTY ON FRI.                             
OUTLOOK...ANOTHER ROUND OF MVFR CONDITIONS SATURDAY AS A

LAKE BREEZE WILL QUICKLY SHIFT BACK TO A MORE SOUTHERLY FLOW BY LATE            
THIS EVENING AS WINDS LINE UP OUT OF THE SOUTH AHEAD OF A COLD FRONT            
THAT WILL MOVE EAST ACROSS THE LAKE FRIDAY.  WITH THE PASSAGE OF THE            
COLD FRONT WINDS WILL KICK UP OUT OF THE SW TO 10 TO 20 KNOTS FRIDAY            
NIGHT AND 15 TO 25 KNOTS SATURDAY AS THE FLOW TURN A LITTLE MORE                
TOWARD THE WEST. THIS WILL MEAN SMALL CRAFT CONDITIONS FOR THE                  
NEARSHORE FOR SATURDAY WHICH PROBABLY WILL CONTINUE INTO EARLY                  
MONDAY IN THE EAST HALF.  WEAK HIGH PRESSURE RIDGING IS EXPECTED

AXIS OF MOISTURE CURRENTLY EXTENDS ALONG THE INDIANA/OHIO

AXIS...A LAYER OF LOW TO MID LEVEL CU ALONG WITH ISOLD SHOWERS                  
CONTINUE TO DECREASE IN COVERAGE AS THEY MOVE CLOSER TO THE CWA.                
OVERNIGHT...A FEW LIGHT SHOWERS OR SPRINKLES WILL WORK THEIR WAY                
INTO THE CWA. WITH TDS AND CLOUD COVERAGE INCREASING...LOW TEMPS                
FOR MUCH OF THE AREA WILL BE THE WARMEST YET THIS MONTH. AS THE H5              
RIDGE EXITS EAST OF THE CWA...THE ERN THIRD OF THE CWA SHOULD                   
SHOULD HAVE SOME RADIATIONAL COOLING WITH CLEAR SKIES BEFORE                    
GIVING WAY TO CLOUD COVERAGE DURING THE EARLY MORNING HRS. LOWS

UPPER LEVEL LOW FORECAST TO ROTATE ACROSS THE UPPER GREAT LAKES                 
FRIDAY INTO SATURDAY...WHILE COLD FRONT MOVES THROUGH OUR AREA                  
DURING THE DAY ON FRIDAY. AS WE GET INTO A MORE FAVORABLE TIME OF DAY           
     EXPECT PCPN TO BECOME MORE WIDESPREAD ACROSS OUR EAST THROUGH              
LATE MORNING AND ON INTO FRIDAY AFTERNOON. SOME VERY LIMITED                    
ELEVATED INSTABILITY DEVELOPS THROUGH EARLY AFTERNOON ACROSS THE                
EAST AND THIS MAY BE ENOUGH FOR AN ISOLATED THUNDERSTORM OR                     
TWO...BUT PREFER TO LEAVE MENTION OUT OF FORECAST AT THIS POINT                 
DUE TO LOW PROBABILITY. WE SHOULD SEE DRY SLOT SLOWLY PUSH INTO                 
THE WEST THROUGH THE DAY AND WOULD NOT BE SURPRISED TO SEE SOME                 
DECENT SUNSHINE IN THE AFTERNOON ACROSS PARTS OF THE WEST. HAVE                 
TRIED TO INDICATE THIS IN THE GRIDS...BUT WILL JUST HAVE PARTLY                 
SUNNY TYPE WORDING IN THE ZONES. WITH SOME UNCERTAINTY IN CLOUD                 
COVER AND BETTER CAA HOLDING OFF UNTIL FRIDAY NIGHT...WILL NOT                  
DEVIATE TOO MUCH FROM GUIDANCE FOR HIGHS ON FRIDAY.                             
CYCLONIC LOW LEVEL FLOW WILL THEN PERSIST ACROSS THE REGION                     
THROUGH THE REMAINDER OF THE SHORT TERM PERIOD. THIS MAY BE ENOUGH              
TO SQUEEZE OUT A FEW SHOWERS...PARTICULARLY ACROSS OUR NORTH                    
WHERE MOISTURE IS A LITTLE BETTER. BEST CHANCE FOR ANY SHOWER                   
ACTIVITY WILL PROBABLY BE DURING THE MORE DIURNALLY FAVORABLE                   
AFTERNOON HOURS. AND WILL PLAY FORECAST ACCORDINGLY.

UNCERTAINTY REMAINS SIGNIFICANT THROUGH THIS PERIOD WITH LARGE                  
DIFFERENCES BETWEEN MODEL RUNS SHOWING UP BY MONDAY NIGHT.  WHAT IS             
CERTAIN IS THAT A LARGE UPPER TROUGH WILL BE IN PLACE ACROSS THE                
REGION TO START OFF THE PERIOD.  WITH CYCLONIC FLOW ACROSS THE GREAT            
LAKES...EXPECT BELOW AVG TEMPS AND MOSTLY CLOUDY CONDITIONS TO START            
OFF THE WEEK.  MAY SEE A FEW LIGHT RAIN OR SNOW SHOWERS ACROSS THE              
NORTHERN CWA ON SUNDAY AS EMBEDDED ENERGY ROTATES AROUND THE UPPER              
LOW.  AFTER THIS...THE LARGE SCALE PATTERN WILL SHIFT TO A BROAD                
UPPER TROUGH OVER THE WESTERN U.S. WITH SOUTHWESTERLY FLOW ACROSS               
THE OHIO VALLEY.  TIMING OF DISTURBANCES IN THIS FLOW PATTERN IS                
DIFFICULT TO DETERMINE SO MODEL SPREAD IS LARGE.  BOTH ECMWF AND GFS            
SEND ENERGY OUT OF THE SOUTHWEST INTO THE OHIO VALLEY EARLY TO MID              
WEEK...BUT TIMING DIFFERENCES ARE SIGNIFICANT.  GFS SEEMS MUCH TOO              
FAST WITH THIS SYSTEM AND THE 00Z ECMWF TOO DEEP.  WENT MUCH CLOSER             
TO A 00Z GFS ENSEMBLE MEAN SOLUTION...WITHOUT MUCH DETAIL IN TIMING             
OF POPS NEXT WEEK DUE TO THE HIGH UNCERTAINTY.  FOR NOW...EXPECT                
RAIN CHANCES TO SPREAD IN FROM THE SOUTHWEST TUES AND WEDS...BUT                
COVERAGE AND TIMING ARE TOO HARD TO PIN DOWN AT THIS POINT.

DECREASE IN THE PRECIP INTENSITY/COVERAGE BY FRIDAY MORNING AS                  
ANOTHER SURGE OF DRY AIR WRAPS INTO THE AREA. TOTAL SNOWFALL                    
AMOUNTS REMAIN SOMEWHAT PROBLEMATIC DUE TO BANDING

FRIDAY AFTERNOON...WITH LOCALLY HIGHER AMOUNTS WITHIN M0RE                      
PERSISTENT BANDS. OF COURSE WITH 40+ MPH WINDS...MEASURING SNOW                 
WITH ANY ACCURACY IS ALWAYS A TREAT. COULD ALSO SEE ANOTHER

INDICATE THAT AREAS WEST OF THE JAMES VALLEY WILL SEE A QUICKER                 
CHANGEOVER TO SNOW DUE TO COLDER SFC TEMPS /LIKELY BY 4PM CST/.

ONCE SNOW BEGINS...BELIEVE WE WILL SEE SOME RATHER IMPRESSIVE                   
SNOWFALL RATES AND REDUCTIONS IN VISIBILITY DUE TO COMBINATION OF               
PLENTIFUL MOISTURE /4 TO 5 G/KG/...STRONG LIFT THROUGH THE                      
DENDRITIC ZONE...AND LOW STATIC STABILITY. SNOWFALL RATES OF AN                 
INCH OR TWO PER HOUR WILL BE POSSIBLE IN HEAVIER BANDS.                         
VISIBILITIES ARE STILL FORECAST TO DROP BELOW 1/4 MILE AT TIMES                 
DUE TO FALLING/BLOWING SNOW...RESULTING IN OCCASIONAL BLIZZARD

GFS/NAM AND LOCAL HIRES WRF-ARW MODELS INDICATE THAT THE HEAVIEST SNOW          
SHOULD GENERALLY FALL BETWEEN 00Z AND 09Z...WITH A GRADUALLY                    
DECREASE IN THE PRECIP INTENSITY/COVERAGE BY FRIDAY MORNING AS                  
ANOTHER SURGE OF DRY AIR WRAPS INTO THE AREA. TOTAL SNOWFALL                    
AMOUNTS REMAIN SOMEWHAT PROBLEMATIC DUE TO BANDING                              
POTENTIAL...BUT BELIEVE A FEW LOCATIONS COULD SEE 4 TO 8 INCHES BY              
FRIDAY AFTERNOON...WITH LOCALLY HIGHER AMOUNTS WITHIN M0RE                      
PERSISTENT BANDS. OF COURSE WITH 40+ MPH WINDS...MEASURING SNOW                 
WITH ANY ACCURACY IS ALWAYS A TREAT. COULD ALSO SEE ANOTHER                     
PERIOD OF LIGHT FREEZING RAIN/DRIZZLE ON FRIDAY AS MODEL SOUNDINGS              
SHOW A LOSS OF ICE IN THE CLOUDS.

FREEZING PRECIPITATION WILL CHANGE OVER TO SNOW AND BE HEAVY AT                 
TIMES. CEILINGS AND VISIBILITY WILL IMPROVE AT TIMES TO NEAR MVFR

BASIN...HAVE NOT YET COME UP TO ADVISORY CRITERIA...BUT THINKING                
IS THAT THEY STILL COULD OVER THE NEXT HANDFUL OF HOURS...GIVEN                 
THAT MANY LOCATIONS HAVE COME CLOSE.                                            
OTHERWISE...WINDS WILL BEGIN TO LAY DOWN TOMORROW AS THE UPPER LEVEL

WEEKEND.  AS THE PACIFIC FRONT CONTINUES MOVING THROUGH THE AREA A              
DRIER AIRMASS WILL BEGIN FILTERING INTO THE AREA EARLY TOMORROW.                
DEWPOINTS WILL BEGIN TO DROP AND BE INTO THE SINGLE DIGITS/TEENS

NEXT WEEK AS THE NEXT BIG SYSTEM WINDS UP TO MOVE NORTH OF THE

BEHIND IT DURING MID WEEK THAT COULD KEEP WINDS UP ACROSS SOME PARTS            
OF THE AREA.  RAINFALL CHANCES CONTINUE TO LOOK SLIM THROUGH MUCH OF

STRONG WESTERLY WINDS AND MINIMUM AFTERNOON RH/S NEAR 15 PERCENT

EXPECTED TO INCREASE TONIGHT...ESPECIALLY WEST OF THE MISSISSIPPI

FORECAST CONCERNS FOCUS ON THE PCPN CHANCES/TIMING FOR TONIGHT AND              
THURSDAY...FOLLOWED BY THE AMOUNT OF COLD AIR AND THEN SNOW CHANCES.            
CURRENTLY...500 MB TROUGH AND ASSOCIATED SHORTWAVE ENERGY DRIVING               
EAST ACROSS THE NORTHERN/CENTRAL PLAINS. AN ASSOCIATED SFC LOW WAS              
LOCATED IN THE SD/NEB VICINITY...WITH A COLD FRONT RUNNING SOUTH OF             
THERE. LATEST 88-D RADAR IMAGERY POINTED TO SCT PCPN ALONG AND AHEAD            
OF THIS FRONT...MOSTLY ASSOCIATED WITH BROAD LOW LEVEL MOISTURE                 
TRANSPORT AND THE LOW LEVEL JET. THE 05.12Z NMM AND NAM12 CONTINUE              
THIS SCT ACTIVITY THIS EVENING...BUT START TO SHIFT THE MAIN PCPN               
FOCUS TO THE WEST...WHERE THE BETTER UPPER LEVEL DYNAMICS OF THE 500            
MB SHORTWAVE TROUGH AND 300 MB JET WILL LIE. THE 05.12Z GFS SUPPORTS            
THIS. STRONG...CURVED UPPER LEVEL JET PROGGED TO ENHANCE ANY                    
CONVECTION OVER MN/IA...ESPECIALLY BETWEEN 06-12Z. FEEL THE ENHANCED            
QPF SIGNALS IN THE MODELS IN DIRECT RELATION TO THIS STRONG JET.                
MEANWHILE...THE LOW LEVEL THERMODYNAMICS/MOISTURE WOULD SEEM TO                 
SUPPORT PCPN CHANCES A BIT MORE EAST. BOTH THE GFS AND NAM POINT A              
STRONG 850 MB JET AND MOISTURE TRANSPORT INTO THE FORECAST AREA BY              
12Z THU. IN ADDITION...GOOD ISENTROPIC UPGLIDE IS INDICATED IN THE              
295-305 K LAYER IN THIS AREA...ALONG WITH SOME 850-700 MB QG                    
CONVERGENCE. HOWEVER...AS MENTIONED...THE GFS AND NAM SEEM TO KEEP              
THEIR QPF ASSOCIATED WITH THE UPPER LEVEL FORCING. THE 05.12Z                   
ARXMESOWRF CHOOSES TO PLACES IT QPF MORE WITH THE LOW LEVEL FORCING.            
THIS HAS A DIRECT BEARING ON THE POPS FOR TONIGHT...AS THE MAJORITY             
OF THE LATEST MODEL RUNS WOULD HOLD OFF ON THE BEST CHANCES UNTIL               
AFTER 12Z...AND THE MODELS HAVE BEEN TRENDING SLOWER OVER THEIR PAST            
COUPLE RUNS. HOWEVER...OTHER THAN THE MESOWRF...FEEL THE MODELS                 
AREN/T CAPTURING THE PCPN POTENTIAL WITH THE LOW LEVEL FORCING. WILL            
LIKELY TRIM BACK POPS A BIT FOR THIS EVENING...WITH BETTER CHANCES              
//MORE WIDESPREAD// OVERNIGHT...BUT CONTINUE THESE CHANCES FARTHER              
EAST THAN THE 12Z RUNS WOULD INDICATE. ONLY A HINT OF SOME MUCAPE               
BETWEEN 06-18Z...BUT WITH THE STRENGTH OF THE LOW LEVEL                         
JET...PROBABLY ENOUGH FOR ISOLATED THUNDER POTENTIAL.                           
THE FRONT WILL SWING NORTHEAST THROUGH THE REGION ON THU...WHILE THE            
SYSTEM ITSELF BECOMES VERTICALLY STACKED FOR A SHORT WHILE. THE                 
BETTER LOW LEVEL FORCING WILL ALSO SHIFT NORTHEAST THROUGH THE DAY              
AS A RESULT...WITH THE SHORTWAVE ENERGY ALSO ON ITS HEELS. THIS                 
SHOULD BRING THE BEST RAIN THREAT WEST OF THE MISSISSIPPI RIVER IN              
THE MORNING...AND THEN EAST FOR THE AFTERNOON. GOOD ENTRAINMENT OF              
DRY AIR POST THE SFC FRONT...PER TIME/HEIGHT X-SECTIONS...AND WILL              
SERVE TO CUTOFF THE PCPN...BUT DON/T EXPECT MUCH CLEARING AT THE                
MOMENT.                                                                         
THE SYSTEM WILL MOVE OVER THE REGION ON FRI...WITH MILD/MOIST AIR               
WRAPPING WELL AROUND THE LOW CENTER. THIS WILL LEAD TO MORE PCPN FOR            
FRI AND SAT...WITH THE SYSTEM EXITING INTO SOUTHEAST CANADA LATE IN             
THE WEEKEND. HOWEVER...COLDER AIR WILL FLOW IN BEHIND THE LOW...AND             
WILL CHANGE THE PCPN CHANCES FROM RAIN TO RAIN/SNOW OR JUST SNOW. AS            
FOR ACCUMULATIONS...RECENT WARMTH SHOULD KEEP MOST ROADS JUST                   
WET...BUT GRASSY SFCS COULD HOLD SOME SNOW. THE 12Z COBB OUTPUT VIA             
THE GFS AND NAM WOULD DROP 1-3 INCHES AT RST FROM LATE FRI NIGHT                
THROUGH SAT. LOOKING AT PREVIOUS COBB OUTPUT...THE TREND IS TO                  
START ACCUMULATIONS SOONER WITH THE 12Z RUN COMPARED TO PREVIOUS                
RUNS...THUS LEADING TO A BIT MORE SNOW ACCUMULATION. FEEL THIS IS               
OVERDONE AT THE MOMENT...ESPECIALLY THE 3 INCH AMOUNT...BUT                     
AGAIN...SOME SNOW ON GRASSY SURFACES ISN/T OUT OF THE QUESTION.                 
BETTER CHANCES LIKELY TO THE WEST...WHERE THE COLDER AIR AND BEST               
FORCING/MOISTURE WILL BE TOGETHER LONGER.                                       
THE STRETCH OF MILD DAYS WILL COME TO AN END ON FRIDAY...AS THE COLD            
AIR WITH THE LOW FULLY SPREADS ACROSS THE REGION. HIGHS IN THE 40S              
WILL RETURN...WITH THIS RETURN TO COLDER TEMPERATURES CONTINUING                
INTO NEXT WEEK.                                                                 
LONG TERM...SUNDAY THROUGH WEDNESDAY                                            
WHILE THE OVERALL UPPER LEVEL PATTERN IS SIMILAR BETWEEN THE GFS AND            
ECMWF...THE DETAILS ON WHERE VARIOUS PACKETS OF SHORTWAVE ENERGY                
WILL TRACK...TIMING/PLACEMENT...ARE QUITE VARIABLE. THEY DO AGREE               
UPON PUSHING THE 500 MB TROUGH/LOW FROM THE EASTERN GREAT LAKES THIS            
WEEKEND INTO SOUTHEAST CANADA FOR EARLY NEXT WEEK. THIS ALLOWS FOR              
SOME WEAK RIDGING TO BUILD IN FROM THE NORTHERN PLAINS...WHILE A                
SHORTWAVE TROUGH MOVES EAST ACROSS THE SOUTHERN PLAINS INTO THE MO              
RIVER VALLEY. AT THE SFC...BOTH THE ECMWF AND GFS DROP A CANADIAN               
HIGH ACROSS THE UPPER MISSISSIPPI RIVER VALLEY FOR THE START OF THE             
NEW WORK WEEK...WHICH WOULD HELP TO KEEP THAT SOUTHERN SHORTWAVE TO             
THE SOUTH. SO...SENSIBLE WEATHER-WISE...THE MODEL DIFFERENCES MAY               
NOT HAVE A BIG IMPACT LOCALLY. THE GFS/ECMWF DO AGREE THAT THE                  
COLDER TEMPS WILL SETTLE IN...WITH HIGHS ONLY IN THE 40S THROUGH AT             
LEAST THE MIDDLE PART OF NEXT WEEK.                                             
&&

LARGE STORM SYSTEM OVER SOUTH DAKOTA WILL EDGE EAST TOWARD THE AREA             
THROUGH 18Z THURSDAY. BIGGEST QUESTION WITH THIS SYSTEM IS WHEN WILL            
THE ASSOCIATED PRECIPITATION IMPACT THE TAF SITES. THE NEW 05.12Z               
NAM AND NMMWRF MODELS NOW SUGGEST THAT THE GREATEST CONCENTRATION OF            
SHOWERS AND THUNDERSTORMS SHOULD OCCUR TO THE SOUTH OF THE TAF SITES            
THROUGH 12Z THURSDAY AS THE MAIN SHORT WAVE TROUGH ROTATES AROUND               
THE BASE OF THE UPPER LEVEL LOW AND INTERSECTS THE LOW LEVEL JET TO             
PRODUCE WIDESPREAD RAINS ACROSS CENTRAL IOWA AND POINTS SOUTH. THE              
MAIN BRANCH OF LOW LEVEL JET DOES NOT GET INTO THE AREA UNTIL LATE              
TONIGHT SO HAVE PUSHED BACK THE TIMING OF THE CATEGORICAL RAIN AND              
MVFR VISIBILITY UNTIL THE 12 TO 15Z TIME FRAME. THERE IS ENOUGH                 
MOISTURE TRANSPORT INTO THE AREA AFTER 06Z TO MOST LIKELY PRODUCE               
SOME SCATTERED ACTIVITY AND WILL HAVE VICINITY SHOWERS TO COVER                 
THIS. SOME ELEVATED INSTABILITY IS PRESENT BUT CONFIDENCE ON WHEN               
AND WHERE ANY THUNDERSTORMS WILL DEVELOP IS TOO LOW TO INCLUDE                  
ANYTHING MORE THAN A CB QUALIFIER AT THIS POINT. ONCE THE RAIN                  
BEGINS EXPECT BOTH MVFR CEILINGS AND VISIBILITY TO BE PRESENT.

FOUND TO THE SOUTH OF THE SFC LOW AS RELATIVELY WARMER AIR HAS                  
WRAPPED AROUND THE NRN SIDE OF THE SYSTEM...OVER THE WRN GRT LAKES              
REGION. THICKNESS FALLS...AND SUB-ZERO 850 TEMPS FOUND ON THE                   
BACK SIDE OF THE SYSTEM ARE PROGGED TO SHIFT EAST INTO THE WRN                  
THIRD OF THE FA THIS AFTERNOON AS SYSTEM PROGRESSES SLOWLY E. THIS              
WILL RESULT IN A PERIOD OF SN MIXING WITH THE RA IN THE WRN                     
AREAS...BEFORE THE LOW LVLS COOL ENOUGH TO SUPPORT ALL SN.                      
HOWEVER...SOME UNCERTAINTY IN SPECIFIC TIMING OF RA TO SN                       
TRANSITION. SUSPECT MODELS ARE ADVANCING SYSTEM E TO QUICKLY. IF                
SO...RA/SN PHASE CHANGE WILL BE LATER INTO THE EVENING FOR THE WRN              
AREAS. OVERNIGHT...MOST MN LOCATIONS CAN EXPECT TO SEE RA IN THE                
EVENING...TRANSITIONING TO A RA/SN MIX OR ALL SN AFTER 06Z. AREAS               
NEAR LAKE SUPERIOR AND IN NW WIS EXPECTED TO REMAIN WARM ENOUGH                 
FOR RA THROUGH MUCH OF THE NIGHT...POSSIBLY MIXING WITH A FEW SNOW              
FLAKES AROUND DAY BREAK SAT. AREAS ALONG THE SOUTH SHORE WILL                   
TRANSITIONING TO SN SAT AFTRN...WITH A FEW INCHES OF ACCUMULATION               
POSSIBLE LATE SAT INTO EARLY SUN. ELSEWHERE...SN ACCUMULATION                   
THROUGH THIS WEEKEND WILL BE MINIMAL. MOST AREAS CAN EXPECT A                   
DUSTING...TO AROUND AN INCH.

.AVIATION...MAINLY MVFR-VFR CONDITIONS EARLY THIS MORNING WILL                  
DETERIORATE TO PRIMARILY IFR-MVFR BY 12Z...AND THEN PERSIST THROUGH             
MUCH OF THE DAY AS AN INTENSE AREA OF LOW PRESSURE SLOWLY PUSHES                
EAST ACROSS MINNESOTA. AREAS OF DRIZZLE AND ASSOCIATED LOW STRATUS              
WILL BE POSSIBLE...ESPECIALLY FROM KDLH AND POINTS NORTH...ALONG THE            
NORTH SHORE THROUGH THIS MORNING. AREAS OF RAIN WILL THEN BECOME                
MORE COMMON...FROM WEST TO EAST...BETWEEN 12Z-18Z. CEILINGS AND VSBYS MAY       
ONCE AGAIN LIFT A BIT DURING THE EARLY AND MID AFTERNOON...BEFORE               
LOWERING AGAIN DURING THE EVENING. RAIN COULD BECOME MIXED WITH SNOW            
AS EARLY AS 18Z FROM KINL SOUTH TO KBRD...BUT WILL LIKELY REMAIN ALL            
LIQUID THROUGH AT LEAST 06Z SATURDAY SOUTH AND EAST OF KDLH. WINDS              
WILL SHIFT TO THE NORTH AND NORTHWEST BY FRIDAY AFTERNOON...WITH                
SOME INCREASE IN SURFACE WIND SPEEDS...ALTHOUGH THE STRONGEST WINDS             
WILL REMAIN JUST SOUTH OF OUR AREA.

WATER VAPOR SHOWING STRONG DARKENING ROTATING AROUND LOW OVER

TROP FOLD TO BRING STRATO AIR DOWN TO AS FAR AS H7 ACCORDING TO                 
LATEST RUC DATA. HOWEVER LOW...IT HAS INDUCED ADDITIONAL                        
CYCLOGENESIS AS SFC ANALYSIS HAS SHOWN A 2MB DROP TO AROUND 994 AS              
CENTER OF CIRCULATION HAS WOBBLED FROM NEAR FAR TO NEAR ATY. NAM/GFS

TIGHTENED ACROSS NORTHEAST CWA AND EXPECT SOME CONVECTIVE MIXING                
GOING ON AS WELL...BUT WIND GUSTS EXCEEDING 50KT HAVE OCCURRED                  
RECENTLY. CALLS TO NORTHERN CHERRY COUNTY WHERE PERSISTANT BAND OF              
SNOW ASSOC WITH TROWAL/MOSITURE WRAPPING AROUND LOW IS KEEPING VSBYS            
UNDER A MILE NEAR KVTN AND 30-40 MILES WEST ALONG HIGHWAY 20. SNOW              
NOT REALLY SIGNIFICANT AND LIMITED TO THAT AREA SO NO HEADLINES                 
PLANNED AND CONDITIONS SHOULD IMPROVE AFTER SUNRISE AS SUBSIDENCE               
AND DRIER AIR GET THROWN INTO THE PICTURE. WINDS SHOULD STAY UP                 
TODAY AND WILL KEEP ADV MOSTLY AS INHERITED...BUT ADD SHERIDAN                  
COUNTY PER LATEST OBS AND START EARLIER IN THE WEST. COLD AIR WILL              
CONTINUE TO WRAP AROUND CYCLONE INTO EASTERN CWA AND TEMPS WILL                 
STRUGGLE TO REACH INTO MID 30S. LACK OF SNOW COVER AND DOWNSLOPE AND            
MAYBE SOME AFTERNOON SUN WILL HELP FAR SW REACH LOWER 50S. UPPER JET

TRIGGER SOME LIGHT SNOW SHOWERS BUT MOST LIKELY NON MEASURABLE                  
FLURRIES SIMILAR TO WHAT IS HAPPENING UPSTREAM ATTM SO WILL LEAVE               
OUT ATTM WITH LOW CONFIDENCE...HOWEVER THIS UPPER LIFT IS MOVING                
OVHD A LLVL THERMAL BOUNDARY. CHANNELIZED VORT ENERGY DROPPING DOWN

BACK SIDE OF JET AND AGAIN LOOKS LIKE BIG CONTRAST BETWEEN LOWER 30S            
NE TO LOWER 50S IN THE FAR SW. THE ARCTIC FRONT LOOKS TO PROGRESS               
WESTWARD AFTER SUNSET AND MOVING INTO WESTER CWA. SOUNDINGS STILL               
SHOW SOME POTENTIAL FOR FREEZING PCPN WITH DRY DENDRTIC LAYER...AND             
HAVE KEPT MENTION OF FZDZ...OR LIGHT SNOW WHICH SEEMS UNLIKELY AS               
LIFT IS MINIMAL AT BEST. AFTER THIS PERIOD MODELS BEGIN TO DIVERGE

14Z WATER VAPOR AND H4 RUC ANALYSIS SHOWING AN AMPLIFIED UPPER LEVEL            
PATTERN ACROSS NORTH AMERICA THIS MORNING. THE FEATURE THAT                     
IMMEDIATELY DRAWS ATTENTION IS THE DEEP LONGWAVE TROUGH OVER THE                
CENTRAL PORTION OF THE CONTINENT ANCHORED BY A STRONG 535DM UPPER               
LEVEL LOW SPINNING OVER THE UPPER MISSISSIPPI VALLEY. THIS LARGE                
SYSTEM ACROSS THE MID-SECTION OF THE COUNTRY IS CURRENTLY FLANKED ON            
BOTH SIDES BY UPPER LEVEL RIDING ALONG BOTH COASTS. THE UPPER LEVEL             
RIDGE IS NOW IN FIRM CONTROL FOR TODAY ALONG THE EAST COAST AS THE              
OLD UPPER LOW THAT HAD BEEN SPINNING OFF THE MID-ATLANTIC STATES                
FINALLY BEGINS TO FILL AND MOVE OFF TOWARD THE CANADIAN MARITIMES.              
STRONG SHORTWAVE EMBEDDED WITHIN THE MAIN TROUGH OVER THE CENTRAL               
PLAINS IS EXTENDING SOUTHWARD INTO THE SOUTHERN PLAINS AS IT ROTATES            
AROUND THE MAIN UPPER LOW. IT WILL BE THIS FEATURE THAT HELPS PROPEL            
THE SURFACE COLD FRONT EASTWARD ACROSS THE FORECAST AREA OVER THE               
NEXT 24 HOURS.                                                                  
AT THE SURFACE...1019MB HIGH PRESSURE IS IN CONTROL OF THE FORECAST             
AREAS THIS MORNING CENTERED AROUND VALDOSTA. HOWEVER...CHANGES ARE              
ON THE WAY AS WE NOW SEE TONIGHT`S COLD FRONT ALIGNED FROM THE                  
CENTRAL TN VALLEY SOUTHWEST INTO NORTHERN AL AND SOUTHERN MS.                   
REGIONAL RADARS SHOWING A SCATTERING OF SHOWERS ALONG AND AHEAD OF              
THIS FRONT STILL WELL TO THE WEST OF OUR ZONES...HOWEVER THE MAIN               
CLOUD SHIELD IS JUST BEGINNING TO ENTER OUR SE AL/PANHANDLE ZONES.              
&&                                                                              
.DISCUSSION/UPDATE...(TODAY THROUGH SATURDAY).                                  
MID-LEVEL SHORTWAVE DISCUSSED ABOVE NOW APPROACHING THE SOUTHERN MS             
VALLEY WILL CONTINUE TO HELP PUSH THE COLD FRONT EASTWARD INTO THIS             
EVENING. AHEAD OF THIS FRONTS PROGRESS...WILL SEE A STEADY INCREASE             
IN CLOUDS WEST OF A LINE FROM AROUND ALBANY TO PANAMA CITY INTO THE             
AFTERNOON HOURS. SHOWER ACTIVITY WILL HOLD OFF FOR THE TIME BEING               
BUT MAY SEE SCT SHOWERS BEGIN TO IMPACT PORTIONS OF SE AL LATE IN               
THE AFTERNOON AND MORE LIKELY TOWARD AND AFTER SUNSET. ANOTHER WARM             
DAY FOR EARLY NOVEMBER UPCOMING WITH UPPER 70S TO PERHAPS 80 EAST OF            
A LINE FROM ALBANY TO TALLAHASSEE WHERE MOSTLY TO PARTLY SUNNY SKIES            
WILL BE THE RULE. FURTHER WEST WHERE CLOUDS WILL BE MORE ON THE                 
INCREASE HIGH TEMPS WILL BE HELD IN THE MIDDLE 70S...BUT STILL                  
NOT BAD FOR THIS TIME OF YEAR.                                                  
COLD FRONT ENTERS THE WESTERN FORECAST AREA DURING THE MIDDLE TO                
LATER EVENING HOURS AND CONTINUES A FAIRLY STEADY EASTWARD                      
PROGRESSION THROUGH THE NIGHT. BEST CHANCES FOR SCT SHOWERS AND                 
PERHAPS AND ISOLATED THUNDERSTORM OVER THE NORTHWEST HALF OF THE                
AREA WILL GENERALLY FALL BEFORE 2 TO 3 AM. THE CHANCES FOR THUNDER              
DO APPEAR RATHER SMALL AT THIS TIME AS THE LARGE SCALE FORCING                  
ASSOCIATED WITH THE SHORTWAVE IS PROGGED TO WEAKEN AND SHEAR OFF TO             
THE NORTHEAST AS IT ENTERS THE REGION. IN ADDITION INSTABILITY IS               
LIMITED AT BEST. IN FACT LATEST SREF PROBABILITIES FOR 500 J/KG                 
(EVEN OVER THE WESTERN ZONES) IS LESS THAN 10% AND LI`S ASSOCIATED              
WITH THE PRE-FRONTAL ENVIRONMENT RISE RAPIDLY TO BETWEEN +2 AND +5              
AFTER SUNSET. EITHER WAY THE BAND OF SHOWERS PROGRESSING EASTWARD               
AHEAD OF THE FRONT SHOULD BE THIN WITH ANY RAINFALL BEING BRIEF IN              
NATURE. THEREFORE ALTHOUGH MOST LOCATIONS WILL SEE A BRIEF SHOWER               
AND HENCE POPS ARE ON THE HIGH SIDE...THE OVERALL IMPACT WILL BE LOW            
AS RAINFALL AMOUNTS ARE ANTICIPATED TO BE LIGHT.                                
COLD FRONT CROSSES THROUGH THE VALDOSTA TO TALLAHASSEE AND                      
APALACHICOLA VICINITY AFTER MIDNIGHT IN THE PRE-DAWN HOURS WITH JUST            
A BRIEF SHOWER POSSIBLE. COLD FRONT LOOKS TO EXIT THE EASTERN PART              
OF THE CWA IN THE FIRST FEW DAYLIGHT HOURS SATURDAY MORNING WITH                
RAPID CLEARING ARRIVING FROM THE WEST AS HIGH PRESSURE BUILDS ALONG             
THE NORTHERN GULF COAST. MUCH DRIER LOW LEVEL AIR WILL ARRIVE DURING            
THE DAY ON SATURDAY...HOWEVER THE AIRMASS IMMEDIATELY BEHIND THE                
FRONT IS NOT ALL THAT MUCH COLDER AND SHOULD STILL ALLOW AFTERNOON              
HIGH TEMPERATURES TO REACH THE LOWER AND MIDDLE 70S. ANY LINGERING              
MORNING CLOUDS ACROSS THE SOUTHEAST HALF OF THE FORECAST AREA SHOULD            
BE EXITING BY EARLY AFTERNOON WITH PARTLY TO MOSTLY SUNNY SKIES                 
AREA-WIDE.                                                                      
&&                                                                              
.MARINE...VERY LIGHT WINDS AND SEAS ONGOING THIS MORNING. STILL                 
EXPECTING A SLOW INCREASE OUT OF THE SOUTH THIS AFTERNOON...                    
ESPECIALLY ACROSS THE WESTERN LEGS AS THE COLD FRONT APPROACHES.                
HOWEVER...WINDS WILL NOT INCREASE ABOVE 15 KNOTS UNTIL THE OVERNIGHT            
HOURS WHEN THE COLD FRONT PASSES AND WINDS TURN TO THE NORTHWEST.               
IT IS LOOKING MORE LIKELY THAT WE WILL SEE A PERIOD OF CAUTIONARY               
CONDITIONS BEHIND THE FRONTAL PASSAGE WITH THE POTENTIAL FOR A BRIEF            
PERIOD OF NEAR ADVISORY WINDS OVER THE WESTERN LEGS. HOWEVER...THE              
SHORT DURATION OF 15 TO 20 KNOT WINDS AND A LIMITED FETCH LENGTH                
WILL KEEP SEAS EVEN WELL OFFSHORE ONLY AROUND 5 FEET. WINDS AND SEAS            
WILL DIMINISH ONCE AGAIN THROUGH THE REMAINDER OF THE WEEKEND AS                
HIGH PRESSURE BUILDS ALONG THE NORTHERN GULF COAST. ANOTHER INCREASE            
IN WINDS WILL BE LIKELY BY TUESDAY AS HIGH PRESSURE BUILDS OFF THE              
MID ATLANTIC COAST AND CREATES A TIGHT PRESSURE GRADIENT ACROSS OUR             
WATERS BETWEEN THIS RIDGE TO THE NORTHEAST AND PALOMA (IN EITHER

AFTER SUNRISE THIS MORNING...WITH PFN OUR ONLY LOCATION AT VFR AS OF            
8 AM EST. FORTUNATELY...IT APPEARS THAT THIS FOG IS VERY                        
SHALLOW...AND MANY LOCATIONS ARE IMPROVING QUITE QUICKLY BETWEEN 8              
AND 9 AM...WITH ONLY TLH HANGING ON TO 1/4 MILE VIS. ONCE THIS FOG              
COMPLETELY LIFTS...EXPECT PARTLY CLOUDY VFR SKIES TO BE THE

APPROACH DHN. ON THE NEXT FULL TAF PACKAGE EARLY THIS AFTERNOON...              
WILL LIKELY ELIMINATE THUNDER FROM THE FCST FOR TONIGHT...AS IT NOW

09Z WV IMAGERY AND RUC ANALYSIS SHOW A LARGE UPPER LOW ROTATING OVER            
SW MN WITH A FAIRLY BROAD UPSTREAM RIDGE OVER THE WRN CONUS. STACKED            
LOW PRESSURE RESULTING IN 998 MB SFC LOW PRES OVER SW MN. TIGHTLY               
PACKED PRESSURE GRADIENT BEHIND THE LOW IS STILL PRODUCING VERY                 
STRONG NW WINDS (GUSTS OVER 40 MPH AT SOME LOCATIONS) ACROSS DAKOTAS            
AND BLIZZARD CONDITIONS OVER CENTRAL SD. OVER OUR AREA...THE                    
INITIAL BAND OF WAA RAIN AHEAD OF THE LOW HAS GENERALLY EXITED ALL              
EXCEPT FAR ERN COUNTIES OF UPR MI. DRY SLOT AS DEPICTED ON FCST                 
SNDGS AND NOTED ON WATER VAPOR LOOP IS MOVING ACROSS MUCH OF THE U.P            
EARLY THIS MORNING. THE DRY SLOT HAS EITHER ENDED THE RAIN OR                   
DIMINISHED PCPN TO -DZ.

GIVEN THE DRY SLOT MOVING OVER THE AREA AND THE SLOWER ADVANCE OF               
THE UPR LOW TODAY TOWARD THE GREAT LAKES AS DEPICTED BY THE 00Z                 
MODELS...HAVE DECIDED TO TRIM BACK COVERAGE OF SHRA TO ISOLD FOR ALL            
BUT THE FAR SW FCST AREA FOR LATE IN THE AFTERNOON.                             
AS THE UPPER LOW SLOWLY SLIDES SOUTH OF THE FCST AREA LATE TONIGHT              
LOOK FOR PCPN IN DEFORMATION ZONE/COMMA HEAD OF UPR LOW TO WRAP BACK            
TOWARD THE WRN FCST AREA ESPECIALLY TOWARD 12Z SAT WHEN MODELS SHOW             
INCREASING ISENTROPIC ASCENT ON THE 290-295K SFC. THUS...HAVE KEPT              
LIKELY POPS OVER THE FAR WEST BUT HAVE TRIMMED BACK POPS TO AROUND              
40 PCT OVER THE FAR EAST DUE TO LACK OF DEEP MOISTURE AND ABSENCE OF            
GOOD ISENTROPIC ASCENT. GIVEN DEGREE OF WARM AIR AT 850 MB (-1 TO               
-2C TEMPS) THAT`S WRAPPING BEHIND THE LOW LOOK FOR PCPN TYPE TO BE              
MOSTLY RAIN TONIGHT.                                                            
AS DEFORMATION ZONE WITH SYSTEM AND IMPRESSIVE 290-295K ISENTROPIC              
ASCENT SPREADS EAST SAT AFTERNOON INTO SAT NIGHT...GRADUALLY UPPED              
POPS TO CATEGORICAL ACROSS THE NRN AND ERN TIER. COLDER 850 MB TEMPS            
OF -8 TO -11C FLOODING ACROSS THE AREA LATE SAT INTO SAT NIGHT WILL             
ENSURE CHANGEOVER FROM LAKE ENHANCED RAIN TO LAKE ENHANCED SNOW.                
GIVEN THE IMPRESSIVE DYNAMICS LATE SAT INTO SAT NIGHT...WOULD EXPECT            
THE POTENTIAL FOR SOME HEAVY WET SNOW OVER WRN AND NCNTRL PORTIONS              
OF THE CWA IN NNW FLOW. ONLY LIMITATION FOR SNOW AMOUNTS IS EXPECTED            
LOW 10/1 SNOW/WATER RATIO AS MODEL SNDGS INDICATE BETTER MODEL OMEGA            
OCCURRING BELOW FAVORABLE DENDRITIC SNOW GROWTH REGION. THUS...AT               
THIS POINT...WOULD NOT ANTIPICATE WARNING SNOW AMOUNTS TO JUSTIFY A             
WATCH BUT I`M PRETTY CONFIDENT THAT ADVISORIES WILL BE NEEDED FOR               
SOME WRN AND PERHAPS NCNTRL COUNTIES. WILL ISSUE A SPS TO HIGHLIGHT             
POTENTIAL FOR SOME HEAVIER WET SNOW LATE SATURDAY INTO SUNDAY.                  
ALTHOUGH PLAINS UPR LOW WILL BE PULLING EAST BY SUN...ANOTHER                   
SHORTWAVE DIVING SOUTH THROUGH THE NRN PLAINS COULD PROVIDE                     
ADDITIONAL ENHANCEMENT FOR LES AND THIS WILL NEED TO BE WATCHED ON              
LATER MODEL RUNS. LINGERING 850 MB TEMPS OF -9 TO -11C AND DEEP                 
CYCLONIC NWRLY FLOW WILL STILL WARRANT LIKELY POPS FOR THE NW                   
SNOWBELTS DOWNWIND OF LAKE SUPERIOR WITH CHC POPS OVER SRN                      
COUNTIES.

THIS MOISTURE WILL LOWER CIGS TO MVFR LATE THIS EVENING THROUGH THE             
OVERNIGHT HOURS TONIGHT AND ALSO BRING A BETTER CHANCE OF RAIN

THEN...AS THE LOW BEGINS TO SHIFT EAST OF LAKE SUPERIOR ON                      
SATURDAY...WINDS INCREASE FROM WEST TO EAST ACROSS LAKE SUPERIOR.               
COLD AIR FLOWING OVR THE WARMER LAKE LEADS TO UNSTABLE LOW LEVELS               
AND GOOD MIXING. THE BETTER MIXING AND TIGHT PRESSURE GRADIENT                  
SHOULD RESULT IN 30 KNOT WINDS WITH POTENTIAL FOR A FEW GALE FORCE              
GUSTS TO 35 KNOTS SATURDAY AFTERNOON/EVENING BEHIND THE COLD FRONT.             
HIGH PRESSURE SLIDING ACROSS THE UPR GREAT LAKES LATER MONDAY

FOCUS FOR THIS MORNING UPDATE IS ON PRECIPITATION CHANGEOVER FROM               
RAIN TO SNOW OVER THE NEXT 24 HOURS. A FEW BANDS OF PRECIPIATIION               
CONTINUE TO MOVE NORTHWEST THROUGH THE NORTHERN TIER...WHILE                    
ADDITIONAL BANDS SCOOT NORTH IN WISCONSIN AHEAD OF THE SURFACE LOW.             
TEMPERATURES IN THE FORECAST AREA STILL REMAIN WARM ENOUGH TO                   
SUPPORT RAIN THROUGH THE MORNING AND EARLY AFTERNOON HOURS. WE ARE              
CONTINUING TO MONITOR AREAS IN NORTHWEST WISCONSIN...ALONG THE                  
SOUTHERN TIER OF BURNETT..WASHBURN...AND SAWYER COUNTIES...AS                   
LOCATIONS JUST TO THE SOUTH...INCLUDING EAU CLAIRE AND UP TO RICE               
LAKE HAVE BEEN WAFFLING BACK AND FORTH BETWEEN RAIN AND SNOW. COLDER            
TEMPERATURES ARE WRAPPING AROUND THE DEEP LOW PRESSURE SYSTEM IN                
SOUTHERN MINNESOTA. BUT...WINDS ARE EXPECTED TO REMAIN EASTERLY IN              
THESE ABOVE MENTIONED COUNTIES...WHICH WILL KEEP THE COOLER AIR TO              
THE SOUTH...UNTIL WINDS TAKE ON A MORE SOUTHERLY TRAJECTORY. THIS               
APPREARS TO OCCUR AFTER 2100 UTC/300 PM CST...AND SO WE HAVE                    
INTRODUCED OCCASIONAL SNOW IN THESE AREAS IN THE LATE                           
AFTERNOON...WITH THE PREDOMINANT PRECIP TYPE AS RAIN...UNTIL AFTER

CONCERNING AREAS FURTHER WEST...BEMIDJI HAS ALSO BEEN TOGGLING                  
BETWEEN RAIN/DRIZZLE/SNOW THIS MORNING...AND THIS IS THE SECOND                 
AREA THAT WILL SEE A CHANGEOVER TO SNOW THIS AFTERNOON. WE HAVE                 
UPDATED THE ZONES TO INDICATE A POTENTIAL CHANGEOEVER IN THE                    
INTERNATIONAL FALLS VICINITY AFTER 1800 UTC...WITH WINDS EXPECTED               
TO BECOME NORTHERLY...AND COMMENCING COLD AIR ADVECTION. FORECAST SOUNDINGS     
INDICATE THAT MUCH OF THE WESTERN TIER OF THE AREA...FROM THE                   
BRAINERD LAKES NORTH TO GRAND RAPIDS WILL REMAIN RAIN THROUGH 0000              
UTC/600 PM CST...THOUGH A FEW SNOW FLAKES DURING THE EVENING                    
COMMUTE ARE NOT OUT OF THE QUESTION WITH 850/925 TEMPS BEING COLD               
ENOUGH. WINDS WILL ALSO BECOME RATHER GUSTY ON THE BACK SIDE OF                 
THE LOW PRESSURE...WHICH WILL REDUCE VISIBILITIES IN AREAS OF                   
SNOW...EVEN THOUGH SNOW IS EXPECTED TO BE LIGHT.

THIRD OF THE FA THIS AFTERNOON AS SYSTEM PROGRESSES SLOWLY E. THIS              
WILL RESULT IN A PERIOD OF SN MIXING WITH THE RA IN THE WRN                     
AREAS...BEFORE THE LOW LVLS COOL ENOUGH TO SUPPORT ALL SN.

DETERIORATE TO PRIMARILY IFR-MVFR BY 12Z...AND THEN PERSIST THROUGH             
MUCH OF THE DAY AS AN INTENSE AREA OF LOW PRESSURE SLOWLY PUSHES                
EAST ACROSS MINNESOTA. AREAS OF DRIZZLE AND ASSOCIATED LOW STRATUS              
WILL BE POSSIBLE...ESPECIALLY FROM KDLH AND POINTS NORTH...ALONG THE            
NORTH SHORE THROUGH THIS MORNING. AREAS OF RAIN WILL THEN BECOME                
MORE COMMON...FROM WEST TO EAST...BETWEEN 12Z-18Z. CEILINGS AND VSBYS MAY       
ONCE AGAIN LIFT A BIT DURING THE EARLY AND MID AFTERNOON...BEFORE               
LOWERING AGAIN DURING THE EVENING. RAIN COULD BECOME MIXED WITH SNOW            
AS EARLY AS 18Z FROM KINL SOUTH TO KBRD...BUT WILL LIKELY REMAIN ALL            
LIQUID THROUGH AT LEAST 06Z SATURDAY SOUTH AND EAST OF KDLH. WINDS              
WILL SHIFT TO THE NORTH AND NORTHWEST BY FRIDAY AFTERNOON...WITH                
SOME INCREASE IN SURFACE WIND SPEEDS...ALTHOUGH THE STRONGEST WINDS

IMPRESSIVE STORM SNOW TOTALS THUS FAR FROM MORNING REPORTS. FAR                 
WESTERN FORECAST AREA WAS HIT HARDEST WITH 12 TO 14 INCHES REPORTED             
ACROSS WESTERN BENSON AND TOWNER COUNTIES...8 INCHES IN LANGDON...              
3 TO 5 INCHES IN DEVILS LAKE...AND 2 INCHES NEAR GRAFTON. MOST                  
AREAS ALONG AND EAST OF THE RED RIVER VALLEY HAVE REMAINED ALL LIQUID           
WITH SURFACE TEMPERATURES SLIGHTLY ABOVE FREEZING.                              
16 UTC RADAR IMAGERY SHOWS TWO REMAINING PRECIPITATION BANDS. THE               
FIRST IS ALL SNOW AND LOCATED FROM JUST WEST OF LANGDON TO                      
CANDO/DEVILS LAKE AND SOUTHWESTWARD TO JUST WEST OF JAMESTOWN. THE              
SECOND BAND IS STILL A MIX OF SNOW...SLEET AND RAIN AND IS LOCATED              
FROM THIEF RIVER FALLS THROUGH CROOKSTON TO JUST NORTH OF FARGO.                
THIS SECONDARY PRECIPITATION BAND FOLLOWS THE SURFACE FREEZING                  
LINE QUITE WELL.                                                                
LOW PRESSURE SYSTEM WILL CONTINUE TO WEAKEN AND SLOWLY MOVE                     
EASTWARD TODAY. WATER VAPOR AND GFS MODEL CROSS SECTION ANALYSIS                
SHOWS MID-LEVEL DEFORMATION ZONE AND TROWAL WEAKENING THROUGH THE               
DAY WITH DECREASING MOISTURE. AS SUCH...CURRENT PRECIPITATION                   
EXPECTED TO WEAKEN TODAY AS IT MOVES EASTWARD...BUT THERE STILL                 
SHOULD EXIST A NARROW AREA OF MIXED PRECIPITATION AS RAIN CHANGES               
TO SNOW ACROSS WEST-CENTRAL AND NORTHWEST MINNESOTA. THE DEVILS                 
LAKE BASIN COULD PICK UP ANOTHER 1 TO 2 INCHES OF SNOW THIS                     
MORNING AND UP TO 1 INCH ELSEWHERE THROUGH 00 UTC THIS EVENING.                 
NORTH WINDS WILL REMAIN STRONG THROUGH THE MORNING...ESPECIALLY                 
WEST OF THE RED RIVER VALLEY...BUT DECREASE THROUGH THE DAY. AS A               
RESULT...BLOWING SNOW WILL REMAIN A PROBLEM IN AREAS THAT RECEIVED              
SIGNIFICANT ACCUMULATIONS CREATING HAZARDOUS DRIVING CONDITIONS.                
WINTER STORM WARNING WILL BE ALLOWED TO EXPIRE AT 18 UTC. WILL                  
SEND OUT UPDATED MORNING GRIDS/FORECAST AT THIS TIME TO COORDINATE              
WITH EXPIRATION STATEMENT. MAIN CONCERN THEREAFTER WILL BE FALLING              
TEMPERATURES IN THE WAKE OF THE LOW REGION-WIDE. HIGH TEMPERATURES              
SATURDAY WILL ONLY BE IN THE UPPER 20S.

CENTRAL PORTION OF THE CONTINENT ANCHORED BY A STRONG 534DM UPPER               
LOW SPINNING OVER THE UPPER MS VALLEY. THIS LARGE SYSTEM ACROSS THE             
MID-SECTION OF THE COUNTRY IS FLANKED ON BOTH SIDES BY UPPER LEVEL              
RIDING ALONG THE COASTS. THE UPPER LEVEL RIDGE IS NOW IN FIRM                   
CONTROL ALONG THE EAST COAST AS THE OLD UPPER LOW THAT HAD BEEN                 
SPINNING OFF THE MID-ATLANTIC STATES FINALLY FILLS AND MOVE OFF                 
TOWARD THE CANADIAN MARITIMES. STRONG SHORTWAVE ROTATING AROUND THE             
MAIN UPPER LOW IS EXTENDING SOUTHWARD INTO THE SOUTHERN PLAINS AND              
APPROACHING THE SOUTHERN/CENTRAL MS VALLEY. IT WILL BE THIS FEATURE             
THAT HELPS PROPEL THE SURFACE COLD FRONT EASTWARD ACROSS THE                    
FORECAST AREA OVER THE NEXT 12 TO 18 HOURS.                                     
AT THE SURFACE...1018MB HIGH PRESSURE IS IN CONTROL OF THE EASTERN              
HALF OF THE FORECAST AREAS THIS AFTERNOON BUT IS BEGINNING TO WEAKEN            
AND MOVE EAST. THIS HIGH IS ON THE MOVE AS TONIGHT`S COLD FRONT                 
CURRENTLY ALIGNED FROM THE EASTERN TN VALLEY SOUTHWEST INTO EASTERN             
AND SOUTHERN AL APPROACHES THE AREA. REGIONAL RADARS SHOWING A                  
FAIRLY SOLID LINE OF SHOWERS AND EMBEDDED THUNDERSTORMS ALONG AND               
AHEAD OF THIS FRONT APPROACHING THE WESTERN ZONES FROM THE WEST.                
THE CLOUD SHIELD IS ALSO OVERSPREADING THE FORECAST AREA FROM WEST              
TO EAST.                                                                        
&&                                                                              
.DISCUSSION/UPDATE...(TONIGHT THROUGH SUNDAY NIGHT).                            
MID-LEVEL SHORTWAVE DISCUSSED ABOVE NOW APPROACHING THE SOUTHERN MS             
VALLEY WILL CONTINUE TO HELP PUSH THE SURFACE COLD FRONT EASTWARD               
INTO THIS EVENING. AHEAD OF THIS FRONTS PROGRESS...WILL SEE A STEADY            
INCREASE IN CLOUDS THIS EVENING WEST OF A LINE FROM AROUND TIFTON TO            
TALLAHASSEE AND APALACHICOLA. SHOWER ACTIVITY STILL CURRENTLY                   
HOLDING OFF TO THE WEST BUT WILL SEE THE CHANCES FOR SCT SHOWERS AND            
STORMS BEGIN INCREASING EARLY THIS EVENING ACROSS OUR SE AL                     
ZONES AND DOWN TOWARD WALTON COUNTY IN THE EASTERN FL PANHANDLE.                
COLD FRONT ENTERS THE WESTERN FORECAST AREA DURING THE MIDDLE TO                
LATER EVENING HOURS AND CONTINUES A FAIRLY STEADY EASTWARD                      
PROGRESSION THROUGH THE NIGHT. BEST CHANCES (IN THE LIKELY CATEGORY)            
FOR SCT SHOWERS AND ISOLATED THUNDERSTORM OVER THE WESTERN HALF OF              
THE AREA WILL GENERALLY OCCUR BEFORE 2 AM. THE CHANCE FOR THUNDER               
EAST OF THE APALACHICOLA RIVER DOES APPEAR RATHER SMALL AT THIS TIME            
AS THE LARGE SCALE FORCING ASSOCIATED WITH THE SHORTWAVE IS PROGGED             
TO WEAKEN AND SHEAR OFF TO THE NORTHEAST AS IT ENTERS THE REGION.               
ONE POSITIVE FACTOR INITIALLY IS A DECENT AREA OF UPPER LEVEL                   
DIVERGENCE ASSOCIATED WITH THE RRQ OF A 120KT 250-300MB JET ROUNDING            
THE BASE OF THE UPPER TROUGH. THIS DIVERGENCE IS RATHER CONCENTRATED            
OVER OUR WESTERN ZONES THIS EVENING AND SHOULD HELP THE LINE OF                 
SHOWERS AND STORMS TO OUR WEST HOLD TOGETHER DURING THE FIRST HALF              
OF THE NIGHT. INSTABILITY ON THE OTHER HAND IS LIMITED AT BEST. IN              
FACT LATEST SREF PROBABILITIES FOR 500 J/KG (EVEN OVER THE WESTERN              
ZONES) ARE LESS THAN 10% OVER INLAND AREAS AND ONLY 20 TO 30% ALONG             
THE PANHANDLE COAST DURING THE FIRST HALF OF TONIGHT. LI`S                      
ASSOCIATED WITH THE PRE-FRONTAL ENVIRONMENT ARE INITIALLY DECENT IN             
THE -1 TO -2 RANGE ACROSS SOUTHERN AL TO OUR WEST BUT RISE ABOVE                
ZERO INTO THE LATER EVENING HOURS AS THE BEST LIFT ARRIVES OVERHEAD.            
LATEST GFS STILL ADVERTISING LI`S AROUND 0 OVER THE WESTERN COASTAL             
WATERS THIS EVENING. SO AS IS OFTEN THE CASE DURING THE COOL                    
SEASON...THE BEST INSTABILITY WILL BE LIMITED TO THE COASTAL WATERS.            
WILL KEEP AN ISOLATED STORM MENTION IN THE FORECAST THROUGH MIDNIGHT            
GENERALLY ALONG AND WEST OF THE APALACHICOLA RIVER FOR OUR LAND                 
ZONES AND A CHANCE MENTION OF THUNDER OFFSHORE. WILL THEN RESTRICT              
WEATHER TYPE WORDING TO ONLY SHOWERS ACROSS THE EASTERN LAND ZONES              
AS THE COLD FRONT CONTINUES TO PROGRESS AND THE THERMODYNAMICS                  
COLLAPSE. EITHER WAY THE BAND OF SHOWERS AHEAD OF THE FRONT SHOULD              
BE RELATIVELY THIN...ESPECIALLY OVER THE EAST...WITH ANY RAINFALL               
BEING BRIEF IN NATURE. AREA-WIDE QPF AMOUNTS WILL GENERALLY FALL                
BETWEEN ONE TENTH AND ONE QUARTER INCH OVER THE WEST (ISOLATED                  
HIGHER AMOUNTS POSSIBLE ASSOCIATED WITH ANY THUNDERSTORMS) AND ONLY             
AROUND ONE TENTH OF AN INCH AT BEST ACROSS THE EAST. THEREFORE                  
ALTHOUGH MOST LOCATIONS WILL SEE A BRIEF SHOWER AND HENCE POPS ARE              
ON THE HIGH SIDE IN PLACES...THE OVERALL IMPACT SHOULD BE LOW.                  
COLD FRONT PROGGED BY ALL GUIDANCE TO EXIT THE EASTERN PART OF THE              
CWA IN THE FIRST FEW DAYLIGHT HOURS SATURDAY MORNING WITH RAPID                 
CLEARING ARRIVING FROM THE WEST AS HIGH PRESSURE BUILDS ALONG THE               
NORTHERN GULF COAST. CAN NOT RULE OUT A BRIEF SHOWER OR SPRINKLE                
ACROSS THE SOUTHEAST FL BIG BEND DURING THE FIRST HALF OF THE                   
MORNING. HOWEVER...GUIDANCE IS IN GOOD AGREEMENT SHOWING THE                    
OVERALL DYNAMICS COLLAPSING ENOUGH TO END ALL SHOWERS AFTER                     
SUNRISE...EXCEPT PERHAPS OVER THE EASTERN COASTAL WATERS. MUCH DRIER            
LOW LEVEL AIR WILL ARRIVE DURING THE DAY ON SATURDAY. THE AIRMASS               
IMMEDIATELY BEHIND THE FRONT IS NOT ALL THAT MUCH COLDER AND SHOULD             
STILL ALLOW AFTERNOON HIGH TEMPERATURES TO REACH THE LOWER AND                  
MIDDLE 70S. ANY LINGERING MORNING CLOUDS ACROSS THE SOUTHEAST HALF              
OF THE FORECAST AREA SHOULD BE EXITING BY EARLY AFTERNOON WITH                  
PARTLY TO MOSTLY SUNNY SKIES AREA-WIDE.                                         
LARGE UPPER LEVEL TROUGH OVER THE EAST SLOWLY DE-AMPLIFIES THROUGH              
THE REMAINDER OF THE SHORT TERM ALLOWING A MORE ZONAL FLOW TO RETURN            
OVERHEAD ALONG THE NORTHERN GULF COAST. AREA WILL BE UNDER CONTROL              
OF SURFACE RIDGING THROUGH THE PERIOD AS HIGH PRESSURE PASSES SLOWLY            
OFF TO NORTHWEST AND EVENTUALLY NORTH SUNDAY NIGHT. THE RESULT IS               
FAIR AND SEASONABLE WEATHER SATURDAY NIGHT INTO EARLY MONDAY MORNING            
WITH COOL NIGHTS (A BIT BELOW CLIMO) AND A NEAR CLIMO DAY IN TERMS              
OF TEMPERATURE ON SUNDAY. LOW TEMPS SAT NIGHT GENERALLY THE LOWER               
AND MIDDLE 40S INLAND AND THE MIDDLE 40S TO NEAR 50 AT THE COAST.               
LOWS SUNDAY NIGHT PERHAPS A FEW DEGREES COOLER AS THE HIGH MAKES                
ITS CLOSEST APPROACH ALLOWING A BETTER RADIATIONAL COOLING SETUP.               
AT THIS TIME...FROST DOES NOT APPEAR LIKELY...BUT WILL KEEP AN EYE              
ON THE SITUATION FOR SOME OF THE NORMALLY COOLER INLAND SPOTS.                  
&&                                                                              
.LONG TERM...(MONDAY THROUGH FRIDAY).                                           
THE PERIOD STARTS OUT DRY WITH CHILLY MORNINGS AS HIGH PRESSURE                 
BUILDS EWD OVER THE SERN STATES. THE LENGTH OF THIS DRY PERIOD IS IN            
DOUBT. IT NOW APPEARS THAT THE LONG WAVE TROUGH DEVELOPING OVER THE             
CENTRAL CONUS EARLY IN THE WORK WEEK WILL BE SLOWER TO MOVE E AND WE            
SHOULD BE ABLE TO KEEP POPS OUT OF THE FORECAST UNTIL WED. AFTER                
THAT TIME...CONFIDENCE IN THE FORECAST DIMINISHES. THE 00Z RUN OF               
THE GFS OFFERS A RATHER DIFFERENT SOLUTION TO THE PREVIOUS RUN,                 
WHICH MATCHED UP WELL WITH THE 06/12Z EURO IN SHOWING A CUT OFF                 
UPPER LOW OVER AR AT 12Z FRI. THE 18Z GFS LIFTED THIS FEATURE NEWD              
WHILE THE EURO MOVED IT BODILY EWD. THE LATEST GFS BRINGS A WEAKER              
UPPER FEATURE EWD MORE QUICKLY. FEEL THE BEST APPROACH AT THIS TIME             
IS TO INTRO SLIGHT CHANCE POPS ON WED AND THEN GRADUALLY INCREASE               
THEM THROUGH THU AND FRI. THIS IS ESSENTIALLY WHAT THE 00Z MEX                  
SHOWS. HOWEVER...WE PLAN TO GO ABOVE THE MOS FOR NEXT FRI.                      
&&                                                                              
.MARINE...VERY LIGHT WINDS AND SEAS CONTINUE THIS AFTERNOON. STILL              
EXPECTING A SLOW INCREASE OUT OF THE SOUTH INTO THE EVENING HOURS...            
ESPECIALLY ACROSS THE WESTERN LEGS AS THE COLD FRONT APPROACHES.                
HOWEVER...WINDS WILL NOT INCREASE ABOVE 15 KNOTS UNTIL THE OVERNIGHT            
HOURS WHEN THE COLD FRONT PASSES AND WINDS TURN TO THE NORTHWEST.               
EXPECTING A PERIOD OF CAUTIONARY CONDITIONS BEHIND THE FRONTAL                  
PASSAGE WITH THE POTENTIAL FOR A BRIEF PERIOD OF NEAR ADVISORY WINDS            
OVER THE WESTERN LEGS. EXPECT CAUTIONARY LEVELS TO CONTINUE INTO THE            
MORNING HOURS OF SATURDAY BEFORE FALLING BELOW CAUTIONARY LEVELS                
DURING THE AFTERNOON. WINDS AND SEAS SHOULD REMAIN BELOW HEADLINE               
CRITERIA THROUGH THE REMAINDER OF THE WEEKEND AS HIGH PRESSURE                  
BUILDS ALONG THE NORTHERN GULF COAST. ANOTHER INCREASE IN WINDS WILL            
BE LIKELY BY TUESDAY AS HIGH PRESSURE BUILDS OFF THE MID ATLANTIC               
COAST AND CREATES A TIGHT PRESSURE GRADIENT ACROSS OUR WATERS                   
BETWEEN THIS RIDGE TO THE NORTHEAST AND PALOMA (IN EITHER TROPICAL              
OR SUBTROPICAL FORM) TO OUR EAST.                                               
&&

VFR CONDITIONS ARE PREVAILING ACROSS THE TAF SITES THIS AFTERNOON               
WITH A SHALLOW SCT CU FIELD DEVELOPING OUT AHEAD OF A WEAK SEA                  
BREEZE IN THE FLORIDA BIG BEND...WHILE INCREASING CU AND BKN AC ARE             
MOVING INTO SE AL AND THE FL PANHANDLE OUT AHEAD OF THE COLD FRONT              
TO OUR WEST. EXPECT THESE CLOUDS TO CONTINUE TO INCREASE FROM THE               
WEST FOR THE REMAINDER OF THE AFTERNOON AND EVENING HOURS...WITH SCT            
SHOWERS DEVELOPING FROM NW TO SE ACROSS THE TAF SITES TONIGHT.                  
CANNOT COMPLETELY RULE OUT AN ISOLATED TSTM AT DHN AND PFN BEFORE               
THE SFC BASED INSTABILITY DIMINISHES...SO LEFT THE TEMPO WX AS                  
SHOWERS WITH A SCT CB CLOUD GROUP FOR THIS PACKAGE. DURING THE SCT              
SHOWERS...EXPECT NO WORSE THAN A PERIOD OF MVFR VIS RESTRICTIONS...             
BUT SINCE THE COLD FRONT WILL TAKE THE LONGEST TO REACH VLD...THERE             
MAY BE A SMALL WINDOW FOR POTENTIAL IFR VIS AND CIGS TO DEVELOP AT              
VLD BETWEEN MIDNIGHT AND 3 AM. ON SATURDAY...THE COLD FRONT SHOULD              
SWEEP QUICKLY EAST OF THE REGION WITH RAPIDLY CLEARING SKIES AND                
LIGHT TO MODERATE N-NW WINDS.                                                   
&&

A WEAKENING COLD FRONT WILL PUSH QUICKLY THROUGH THE REGION TONIGHT             
WITH SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ...AND THEN MUCH              
DRIER AIR BUILDING INTO THE AREA FOR THE UPCOMING WEEKEND. THIS DRY             
AIR WILL COMBINE WITH STRONG TRANSPORT WIND SPEEDS TO ALLOW                     
DISPERSIONS TO EXCEED 75 ACROSS THE FLORIDA BIG BEND AND PANHANDLE              
EACH AFTERNOON. THESE HIGH DISPERSIONS ALONG WITH RELATIVE                      
HUMIDITIES LESS THAN 35 PERCENT WILL CREATE IDEAL RED FLAG                      
CONDITIONS ACROSS FOR MUCH OF NORTH FLORIDA. OVER SOUTHEAST ALABAMA             
AND SOUTHWEST AND SOUTH CENTRAL GEORGIA...ONLY BRIEF DURATIONS OF 25            
PERCENT RELATIVE HUMIDITY OR BELOW ARE EXPECTED AT THIS TIME.

WOULD REACH THE GROUND.                                                         
TOMORROW-TOMORROW NIGHT...SHORT WAVE RIDGING WILL BE PRIMARY FORCING            
ACROSS THE AREA. DESPITE RIDGING ALOFT...FRONTAL ZONE IS EXPECTED TO            
BACK INTO THE REGION DURING THE LATE AFTERNOON. OVERNIGHT...FAIRLY              
STRONG WAA DEVELOPS AT H85 AND H7. DIV Q FIELDS INDICATE THAT TEMP              
ADVECTION SUFFICIENT FORCING FOR ASCENT DESPITE APPROACHING RIDGE               
AXIS...AND POINT SOUNDINGS INDICATE ASCENT INCREASING IN THE H85 TO             
H75 LAYER. THE OVERALL PATTERN WOULD FIT FOR -FZDZ IN SOME                      
AREAS....BUT QUESTIONS STILL REMAIN ON THE QUALITY OF MOISTURE                  
RETURN BEHIND THE FRONT. NAM SUGGEST TD`S IN THE LOWER 30S WILL                 
DEVELOP BEHIND THE FRONT...WHILE THAT SEEMS A BIT ON THE HIGH SIDE              
THERE ARE TD VALUES THIS HIGH UPSTREAM IN MONTANA. EVEN IF THE                  
MOISTURE RETURN IS AS STRONG ASS ADVERTISED...POINT SOUNDINGS STILL             
INDICATE BOUNDARY LAYER NEVER SATURATES WHICH WOULD TEND TO FAVOR               
STRATUS OVER ANY KIND OF -FZDZ. EITHER WAY...CURRENT SLIGHT CHANCE              
POPS LOOK REASONABLE AT THIS TIME.                                              
SUNDAY-SUNDAY NIGHT...POTENTIAL FOR PATCHY FZDZ WILL CONTINUE IN THE            
MORNING...BUT SHORT WAVE RIDGE AXIS WILL BECOME CENTERED OVER THE               
AREA DURING THE EARLY AFTERNOON BRINING AN END TO PRECIP CHANCES.               
FROM THIS POINT IN THE FORECAST MODELS DIVERGE INTO TWO SEPARATE                
CAMPS THAT ARE MENTIONED IN A BIT MORE DETAIL IN THE EXTENDED                   
SECTION. WITH SUCH LARGE DIFFERENCES HARD TO PIN DOWN SPECIFICS ON              
AREAS WHERE BEST FORCING WILL LINE UP AND TRIED TO KEEP FORECAST                
GENERAL WITH RESPECT TO POPS AND PRECIP AMOUNTS. EXPECT STRONG                  
TROUGH TO BEGIN TO OVERSPREAD THE AREA OVERNIGHT. LAPSE RATES AHEAD             
OF THIS SYSTEM ARE FAIRLY STEEP FOR THIS TIME OF YEAR WITH H7-H5                
LAPSE RATES 7-8C/KM OVERNIGHT SUNDAY. WITH STRONG FORCING AND WEAK              
STABILITY WOULD EXPECT A STRONG RESPONSE TO THE APPROACHING TROUGH.             
ORIGINALLY PLANNED TO KEEP FORECAST ALL SNOW...BUT NAM AND 12Z ECMWF            
INDICATE POTENTIAL FOR A PERIOD OF MIXED PRECIPITATION WITH WARM                
LAYER ALOFT. ALTHOUGH THE PLACEMENT OF THE FREEZING/FROZEN/LIQUID               
LINE VARIES SIGNIFICANTLY FROM MODEL TO MODEL...WILL LEAN TO A MORE             
MIXED PCP EVENT EARLY ACROSS THE AREA AS A KIND OF WORST CASE                   
SCENARIO.                                                                       
IN THE EXTENDED...MAIN CONCERN FOR THE PERIOD WILL CENTER AROUND                
POTENTIAL SNOW STORM ACROSS THE AREA MONDAY AND TUESDAY. OPERATIONAL            
MODELS STILL IN TWO DISTINCT CAMPS. GFS...84 HR NAM AND LATEST SREF             
SUGGEST A MORE OPEN PROGRESSIVE SYSTEM...WHILE THE                              
CANADIAN/ECMWF/UKMET SUPPORT A STRONG NEGATIVELY TILTED TROUGH TO               
IMPACT THE AREA MONDAY AND TUESDAY. SOME 00Z GFS ENS SOLUTIONS                  
SUPPORT THE STRONGER SOLUTION...WHILE 00Z CANADIAN ENSEMBLES                    
STRONGLY SUPPORT THE NEGATIVELY TILTED TROUGH. ALTHOUGH THERE                   
REMAINS A LARGE AMOUNT OF UNCERTAINTY WITH RESPECT TO STRENGTH OF               
THE SYSTEM AND LIKELY AMOUNTS...INDICATIONS INDICATE THAT HIGHER                
POPS ARE WARRANTED. ALTHOUGH THERE MAY BE SOME MIXED PRECIPITATION              
EARLY ON MONDAY...WITH THE EXPECTED STRONG LIFT AND COOLER WET BULB             
TEMPS...WILL KEEP FCST SIMPLE AND CALL PRECIP ALL SNOW FROM MONDAY              
MORNING ON. LOWERED TEMPERATURES SEVERAL DEGREES TO START THE WEEK              
DUE TO THE PREVIOUSLY MENTIONED STORM. OTHERWISE...UNCERTAINTY VERY

.SYNOPSIS...                                                                    
WATER VAPOR IMAGERY AND RUC ANALYSIS SHOW A LARGE MID/UPPER LOW                 
CENTERED OVER NE IA/SE MN WITH OBS INDICATING SFC LOW PRES                      
CO-LOCATED WITH THE MID/UPPER CENTERS. SINCE SYSTEM HAS BEEN                    
OCCLUDED FOR SOMETIME...850MB THERMAL TROF HAS WRAPPED WELL AROUND              
THE S SIDE OF SYSTEM WITH CAA INTO UPPER MI OCCURRING FROM THE S                
THIS AFTN. AS A RESULT...PCPN CHANGEOVER FROM RAIN TO SNOW HAS ALSO             
BEEN PROGRESSING SLOWLY N AND E ACROSS WRN WI TODAY...BUT PROGRESS              
HAS SLOWED CONSIDERABLY DURING THE AFTN HRS. NOT MUCH IF ANY PCPN               
HAS OCCURRED OVER THE FCST AREA SINCE SUNRISE AS DRY SLOT SURGED                
INTO UPPER MI OVERNIGHT/THIS MORNING.                                           
&&                                                                              
.SHORT TERM (TONIGHT AND SAT)...                                                
BIG CHALLENGE IN THE SHORT TERM IS TIMING CHANGEOVER FROM RAIN TO               
SNOW FROM SW TO NE ACROSS FCST AREA TONIGHT/SAT. SNOW FCST IS MOST              
CRITICAL OVER THE W WHERE LAKE ENHANCEMENT WILL BECOME INVOLVED SAT.            
EXACTLY WHEN CHANGEOVER OCCURS WILL BE CRITICAL TO DETERMINING HOW              
MUCH SNOW MAY FALL...ESPECIALLY OVER THE FAR W AROUND KIWD.                     
PCPN CURRENTLY WRAPPING AROUND THE MIDEVEL LOW CENTER WILL GRADUALLY            
SPREAD INTO THE FCST AREA TONIGHT. WILL THUS GRADUALLY INCREASE POPS            
FROM THE W AND S TO THE N AND E DURING THE NIGHT. BUMPED UP POPS TO             
LIKELY OR BETTER ALL AREAS SINCE SOME MEASURABLE PCPN SEEMS A GOOD              
BET. OVER THE W...ISENTROPIC ASCENT AS VIEWED ON THE 290K SFC                   
WILL BE INCREASING OVERNIGHT. 850MB TEMPS DROPPING TO AROUND -1C                
OVER THE WRN LAKE WILL ALSO BE SUFFICIENT FOR LAKE ENHANCEMENT TO               
GET UNDERWAY LATE TONIGHT AS LOW-LEVEL WINDS BECOME NNE AND                     
STRENGTHEN TO 25-35KT. CATEGORICAL POPS WILL BE UTILIZED THERE                  
OVERNIGHT. WILL NEED TO WATCH FOR LAKE ENHANCEMENT OFF LAKE MICHIGAN            
AS WELL...WHICH MAY REQUIRE BUMPING UP POPS FURTHER IN THAT AREA. AS            
FOR PTYPE...WEDGE OF WARM AIR WRAPPED AROUND THE N SIDE OF MID LEVEL            
LOW WILL ONLY GRADUALLY COOL TONIGHT AS SYSTEM TRANSLATES E...                  
PUSHING MAIN THRUST OF CAA ACROSS WI INTO LWR MI. AS A RESULT...                
NAM/GFS SHOW FREEZING LEVEL REMAINING ABOVE 1.5KFT AGL THRU 12Z SAT             
ACROSS THE WRN...NRN AND ERN FCST AREA. THE GFS IS SLIGHTLY WARMER              
THAN THE NAM AND IS PREFERRED DUE TO ITS SLIGHTLY BETTER ANALYSIS OF            
TEMPS AROUND THE MIDLEVEL LOW THIS MORNING PER 12Z RAOBS. AS A                  
RESULT...PTYPE SHOULD REMAIN MOSTLY RAIN THRU THE NIGHT. A MIX OR               
CHANGE TO SNOW AS PTYPE SHOULD ONLY OCCUR OVER THE SCNTRL WHERE                 
FREEZING LEVEL DROPS TO AROUND 1KFT AGL.                                        
ON SAT...DEFORMATION ZONE/ISENTROPIC ASCENT REGIME WILL SPREAD E                
ACROSS THE FCST AREA. WITH SUFFICIENTLY COLD AIR OVER LAKE                      
SUPERIOR...LAKE ENHANCEMENT AS WELL AS TERRAIN ENHANCEMENT SHOULD               
PLAY A BIG ROLE IN PCPN COVERAGE/INTENSITY. WIND SHIFT TO THE N WILL            
TRANSLATE E ACROSS LAKE SUPERIOR/UPPER MI IN THE WAKE OF POSSIBLE               
DEVELOPING MESO LOW ON LAKE SUPERIOR...SO POPS WILL SHOW AN                     
INCREASING TREND TO CATEGORICAL EWD INTO NCNTRL UPPER MI SAT.                   
OTHERWISE...WITH DEFORMATION ZONE PASSING ACROSS THE AREA...LIKELY              
POPS ARE WARRANTED ACROSS THE ENTIRE AREA. GFS SHOWS RAPID LOWERING             
OF THE FREEZING LEVEL TO UNDER 1KFT AGL OVER WRN UPPER MI SAT                   
MORNING AND INTO PORTIONS OF CNTRL UPPER MI IN THE AFTN. THUS...                
EXPECT A CHANGEOVER TO MAINLY SNOW AWAY FROM LAKE SUPERIOR ACROSS               
THE W HALF OF UPPER MI SAT. GIVEN THE UNCERTAINTY OF EXACT TIMING OF            
CHANGE TO SNOW...SNOW FALLING DURING THE DAYLIGHT HRS AND WARM                  
GROUND...SNOW ACCUMULATIONS ARE VERY UNCERTAIN TO SAY THE LEAST. FOR            
NOW...STAYED CLOSE TO PREVIOUS FCST. SLOPPY SNOW ACCUMULATIONS ON               
GRASSY AREAS MAY REACH 3-4INCHES OVER THE HIGHER TERRAIN FROM AROUND            
KIWD TO ROCKLAND...WITH MAYBE A COUPLE OF INCHES OVER THE HIGHER                
TERRAIN OF THE KEWEENAW TO WRN MARQUETTE COUNTY.                                
.LONG TERM (SAT NIGHT THROUGH NEXT FRIDAY)...                                   
PERIOD BEGINS AS UPPER/SFC LOW IS LOCATED JUST SOUTH OF HUDSON BAY              
AND DRIFTING FARTHER TO THE NNE. DEFORMATION/COMMA HEAD PCPN WILL BE            
TRANSITIONING E ACROSS THE CWA DURING THE EVENING...WHILE AN                    
ELONGATED SFC TROUGH FROM THE MAIN LOW SLIDES E OF THE CWA.                     
REINFORCING SHORTWAVE IS PROGGED TO DROP S AROUND THE UPPER LOW ON              
SAT NIGHT OVER FAR WRN UP...COINCIDING WITH SFC TROUGH DIVING S. GFS            
IS SLIGHTLY TO THE EAST WITH THE WAVE...WITH NAM/ECMWF/GEM DROPPING             
IT ACROSS NRN MN...FAR WRN LK SUPERIOR...AND INTO NW WI. ABUNDANT               
FORCING PRESENT WITH LEFT EXIT REGION OF WEAK JET JUST TO THE W OF              
THE CWA AND STRONG Q VECTOR CONVERGENCE ABOVE H500 SPREADING E                  
ACROSS THE CWA WILL LEAD TO WIDESPREAD PCPN ACROSS THE AREA...WITH              
LAKE ENHANCEMENT IN LOCATIONS FAVORED BY A NNW WIND NEAR LK                     
SUPERIOR. COLD AIR WILL DIVE S BEHIND THE SFC TROUGH AND                        
SHORTWAVE...WITH H850 TEMPS FALLING FROM -7C AT 00Z SUN TO -10C AT              
12Z SUN OVER THE WRN PART OF THE CWA. WITH LK SUPERIOR TEMPS AROUND             
7/8C...THIS PRODUCES DELTA T VALUES AROUND 14-17. THE INCREASING                
DELTA T VALUES ALONG WITH A RISING INVERSION HEIGHT ON SAT                      
NIGHT...TO AROUND H750 BY 12Z SUN ON NAM/GFS BUFKIT SOUNDINGS...WILL            
LEAD TO INTENSIFYING PCPN IN LK EFFECT AREAS. PCPN SHOULD BE ALL                
SNOW OVER THE WRN PART OF THE CWA FOR SAT NIGHT...AS TEMPS CONTINUE             
TO FALL. BUFKIT SOUNDINGS SHOW PLENTY OF MOISTURE THROUGH THE                   
INVERSION AND TEMPS COLD ENOUGH FOR ICE CRYSTALS. THINK THE SNOW                
RATIO WILL BE ON THE LOWER SIDE FOR LK EFFECT DURING THE                        
EVENING...AROUND 10 TO 1...DUE TO DEEP CLOUD DEPTH...INITIAL                    
SYNOPTIC FORCING...AND DGZ LOCATED NEAR THE INVERSION HEIGHT. DID               
START TO TREND SNOW RATIOS UP OVERNIGHT...BUT ONLY TO 11/12 TO 1                
RANGE...AS PCPN TRANSITIONS TO MORE TRADITIONAL LES. AS FOR THE ERN             
PART OF THE CWA...STARTED OFF WITH A RAIN AND SNOW MIX DURING THE               
EVENING...THEN QUICKLY TRANSITIONED TO ALL SNOW OVERNIGHT. BUFKIT               
SOUNDINGS SHOW RAPID COOLING ALOFT AFTER 03Z...WHICH ELIMINATES THE             
SHALLOW WARM LAYER OF 1.5KFT NEAR THE SFC. OVERALL...WILL PROBABLY              
SEE 2-4 INCHES OF SNOW OVER THE WEST ON SAT NIGHT...WITH SOME                   
LOCALLY HIGHER AMOUNTS IN THE TRADITIONAL LES LOCATIONS AND HIGHER              
ELEVATIONS. THIS PUTS IT RIGHT ON THE EDGE OF ADVISORY CRITERIA AND             
THINK ISSUING ONE FOR SOME OF THE WRN COUNTIES IS LIKELY IN THE                 
COMING SHIFTS.                                                                  
EXPECT THE LES TO CONTINUE ON SUN AS WINDS GRADUALLY BACK TO THE NW             
THROUGH THE DAY. H850 TEMPS REMAIN FAVORABLE FOR LES...WITH -9C OVER            
THE E AND -11C OVER THE W...WITH PLENTY OF MOISTURE THROUGH THE                 
INVERSION. THUS HAVE BUMPED UP POPS IN THE FAVORABLE LES REGIONS FOR            
SUN. THINK THE SNOW/WATER RATIO WILL BE A LITTLE HIGHER ON SUN...AS             
DGZ STARTS TO COINCIDE WITH THE BEST OMEGA OVER THE EAST. THINK                 
ALGER AND LUCE COUNTIES WILL SEE THE MOST SNOW ON SUN...CURRENTLY               
AROUND 2-3 INCHES...DUE TO THE LONGER FETCH WITH THE NW WINDS. REST             
OF THE FAVORABLE LES AREAS WILL SEE A COUPLE OF INCHES ON SUN. LES              
MAY GET SOME UPPER LEVEL SUPPORT ON SUN EVENING THROUGH MON...AS A              
SERIES OF SHORTWAVES MOVE AROUND THE UPPER LOW. HAVE EXTENDED THE               
PCPN CHANCES IN THE NW WIND AREAS DURING THIS TIME...AS PLENTY OF               
MOISTURE REMAINS BELOW THE INVERSION AND DELTA T VALUES ARE STILL               
FAVORABLE. LES WILL BEGIN TO TAPER OFF OVER THE W ON MON AFTN...AS              
THE INVERSION HEIGHTS FALL TOWARDS 4KFT AND DRIER AIR ALOFT MOVES IN.           
BROAD TROUGH OVER THE WRN CONUS ON ECMWF/GFS/GFS ENS ON TUES...WITH             
SFC HIGH NEAR THE REGION. THERE ARE DIFFERENCES IN THE INTENSITY AND            
POSITION OF THE SFC HIGH...BUT ECMWF/GFS ENS ARE BOTH INDICATING A              
BROAD HIGH OF 1025-1032MB STRETCHING FROM THE UPPER MIDWEST THROUGH             
THE GREAT LAKES AND INTO THE NE US. WITH THE HIGH MOVING IN ON TUES             
AND H850 TEMPS GRADUALLY WARMING...IT SHOULD BRING AN END TO THE LK             
EFFECT SNOW OVER THE ERN UP BY TUES NIGHT. DID HAVE THE LK EFFECT               
SNOW A LITTLE LONGER ON TUES...AS ECMWF/GFS ENS STILL SHOWING                   
FAVORABLE NW WINDS AND H850 TEMPS LINGERING INTO THE AFTN AND A                 
POSSIBLE WEAK TROUGH ROTATING AROUND THE LOW. UPPER TROUGH LOOKS TO             
SLOWLY TRANSITION E TUES NIGHT THROUGH FRI...AS RIDGE BUILDS OVER               
THE W COAST DUE TO STRONG JET COMING ONSHORE. HAVE KEPT TUES NIGHT              
THROUGH THURS DRY...AS HIGH TAKES HOLD OVER THE REGION. THE HIGH                
SHOULD KEEP THE DEVELOPING LOW OVER THE SRN PLAINS S OF THE                     
AREA...TRACKING ALONG THE OHIO RIVER VALLEY. TEMPS WILL BE AT OR                
SLIGHTLY BELOW NORMAL TUES AND WED UNDER THE HIGH. SOME DIFFERENCES             
START TO SHOW IN DAYS 6/7 WITH THE HANDLING OF THE UPPER                        
TROUGH...BUT IT LOOKS LIKE THE UPPER TROUGH AND ASSOCIATED CANADIAN

UPDATED AVIATION DISCUSSION FOR 18Z TAF ISSUANCE                                
.SYNOPSIS... ISSUED AT 6 AM EST                                                 
09Z WV IMAGERY AND RUC ANALYSIS SHOW A LARGE UPPER LOW ROTATING OVER            
SW MN WITH A FAIRLY BROAD UPSTREAM RIDGE OVER THE WRN CONUS. STACKED            
LOW PRESSURE RESULTING IN 998 MB SFC LOW PRES OVER SW MN. TIGHTLY               
PACKED PRESSURE GRADIENT BEHIND THE LOW IS STILL PRODUCING VERY                 
STRONG NW WINDS (GUSTS OVER 40 MPH AT SOME LOCATIONS) ACROSS DAKOTAS            
AND BLIZZARD CONDITIONS OVER CENTRAL SD. OVER OUR AREA...THE                    
INITIAL BAND OF WAA RAIN AHEAD OF THE LOW HAS GENERALLY EXITED ALL              
EXCEPT FAR ERN COUNTIES OF UPR MI. DRY SLOT AS DEPICTED ON FCST                 
SNDGS AND NOTED ON WATER VAPOR LOOP IS MOVING ACROSS MUCH OF THE U.P            
EARLY THIS MORNING. THE DRY SLOT HAS EITHER ENDED THE RAIN OR                   
DIMINISHED PCPN TO -DZ.                                                         
&&                                                                              
.DISCUSSION... ISSUED AT 6 AM EST                                               
GIVEN THE DRY SLOT MOVING OVER THE AREA AND THE SLOWER ADVANCE OF               
THE UPR LOW TODAY TOWARD THE GREAT LAKES AS DEPICTED BY THE 00Z                 
MODELS...HAVE DECIDED TO TRIM BACK COVERAGE OF SHRA TO ISOLD FOR ALL            
BUT THE FAR SW FCST AREA FOR LATE IN THE AFTERNOON.                             
AS THE UPPER LOW SLOWLY SLIDES SOUTH OF THE FCST AREA LATE TONIGHT              
LOOK FOR PCPN IN DEFORMATION ZONE/COMMA HEAD OF UPR LOW TO WRAP BACK            
TOWARD THE WRN FCST AREA ESPECIALLY TOWARD 12Z SAT WHEN MODELS SHOW             
INCREASING ISENTROPIC ASCENT ON THE 290-295K SFC. THUS...HAVE KEPT              
LIKELY POPS OVER THE FAR WEST BUT HAVE TRIMMED BACK POPS TO AROUND              
40 PCT OVER THE FAR EAST DUE TO LACK OF DEEP MOISTURE AND ABSENCE OF            
GOOD ISENTROPIC ASCENT. GIVEN DEGREE OF WARM AIR AT 850 MB (-1 TO               
-2C TEMPS) THAT`S WRAPPING BEHIND THE LOW LOOK FOR PCPN TYPE TO BE              
MOSTLY RAIN TONIGHT.                                                            
AS DEFORMATION ZONE WITH SYSTEM AND IMPRESSIVE 290-295K ISENTROPIC              
ASCENT SPREADS EAST SAT AFTERNOON INTO SAT NIGHT...GRADUALLY UPPED              
POPS TO CATEGORICAL ACROSS THE NRN AND ERN TIER. COLDER 850 MB TEMPS            
OF -8 TO -11C FLOODING ACROSS THE AREA LATE SAT INTO SAT NIGHT WILL             
ENSURE CHANGEOVER FROM LAKE ENHANCED RAIN TO LAKE ENHANCED SNOW.                
GIVEN THE IMPRESSIVE DYNAMICS LATE SAT INTO SAT NIGHT...WOULD EXPECT            
THE POTENTIAL FOR SOME HEAVY WET SNOW OVER WRN AND NCNTRL PORTIONS              
OF THE CWA IN NNW FLOW. ONLY LIMITATION FOR SNOW AMOUNTS IS EXPECTED            
LOW 10/1 SNOW/WATER RATIO AS MODEL SNDGS INDICATE BETTER MODEL OMEGA            
OCCURRING BELOW FAVORABLE DENDRITIC SNOW GROWTH REGION. THUS...AT               
THIS POINT...WOULD NOT ANTIPICATE WARNING SNOW AMOUNTS TO JUSTIFY A             
WATCH BUT I`M PRETTY CONFIDENT THAT ADVISORIES WILL BE NEEDED FOR               
SOME WRN AND PERHAPS NCNTRL COUNTIES. WILL ISSUE A SPS TO HIGHLIGHT             
POTENTIAL FOR SOME HEAVIER WET SNOW LATE SATURDAY INTO SUNDAY.                  
ALTHOUGH PLAINS UPR LOW WILL BE PULLING EAST BY SUN...ANOTHER                   
SHORTWAVE DIVING SOUTH THROUGH THE NRN PLAINS COULD PROVIDE                     
ADDITIONAL ENHANCEMENT FOR LES AND THIS WILL NEED TO BE WATCHED ON              
LATER MODEL RUNS. LINGERING 850 MB TEMPS OF -9 TO -11C AND DEEP                 
CYCLONIC NWRLY FLOW WILL STILL WARRANT LIKELY POPS FOR THE NW                   
SNOWBELTS DOWNWIND OF LAKE SUPERIOR WITH CHC POPS OVER SRN                      
COUNTIES.

SFC LOW OVER SOUTHERN MN DRIFTS NORTHEAST ACROSS THE UPPER GREAT                
LAKES THROUGH SATURDAY AFTN. LIGHT PRESSURE GRADIENT WITH THE LOW

THEN...AS THE LOW BEGINS TO SHIFT EAST OF LAKE SUPERIOR ON                      
SATURDAY...WINDS INCREASE FROM WEST TO EAST ACROSS LAKE SUPERIOR.               
COLD AIR FLOWING OVR THE WARMER LAKE LEADS TO UNSTABLE LOW LEVELS               
AND GOOD MIXING. THE BETTER MIXING AND TIGHT PRESSURE GRADIENT                  
SHOULD RESULT IN 30 KNOT WINDS WITH POTENTIAL FOR A FEW GALE FORCE              
GUSTS TO 35 KNOTS SATURDAY AFTERNOON/EVENING BEHIND THE COLD FRONT.             
HIGH PRESSURE SLIDING ACROSS THE UPR GREAT LAKES LATER MONDAY

.SHORT TERM (TONIGHT AND SATURDAY)...LATEST RUC ANALYSIS AND                    
VIS/IR/WV/RADAR IMAGERY SHOW AN OCCLUDED LOW DRIFTING EAST ALONG                
THE MN/IA BORDER...WITH AN SECONDARY COLD FRONT PINWHEELING AROUND              
INTO SE WISCONSIN. BAND OF PRECIP AHEAD OF THIS COLD FRONT IS                   
SHIFTING INTO THE SW FORECAST AREA WHILE AREAS FARTHER NE HAVE                  
SEEN CLOUDS INCREASE THROUGH THE AFTERNOON. PRECIP TYPE HAS BEEN                
ALL OF THE LIQUID VARIETY SO FAR...BUT MIXED AND FROZEN PRECIP                  
LURK JUST UPSTREAM BACK TOWARDS LACROSSE. AS THE UPPER LOW PIVOTS               
SLIGHTLY NORTH OF DUE EAST...PRECIP TIMING/TYPE AND ACCUMULATIONS               
REMAIN THE PRIMARY FORECAST CONCERNS THROUGH TOMORROW.                          
TONIGHT...THE SECONDARY COLD FRONT ALONG WITH ITS ASSOCIATED RAIN               
BAND WILL ROTATE NE LATE THIS AFTERNOON AND EVENING ACROSS THE                  
FORECAST AREA.  SOME OF THE RAIN ON ITS BACK EDGE WILL BEGIN TO MIX             
WITH SNOW OVER THE SW FORECAST AREA AS SLIGHTLY COLDER AIR WORKS                
NE.  BETTER CHANCES OF SNOW WILL ARRIVE LATER THIS EVENING INTO THE             
OVERNIGHT...WHEN A POCKET OF DEEP MOISTURE WITHIN THE UPPER LOW                 
ITSELF INTERACTS WITH COOLING BOUNDARY LAYER TEMPS AS IT PASSES                 
ACROSS NE WISCONSIN.  AREAS ADJACENT TO GREEN BAY AND LAKE MICHIGAN WILL        
REMAIN LIQUID THE LONGEST AS A RESULT OF LOWER ELEVATIONS AND LAKE              
MODIFICATION...AND MAY NOT CHANGE OVER TO COMPLETELY ALL SNOW AT                
ALL.  HIGHEST ACCUMULATIONS SHOULD REMAIN AT OR AROUND AN INCH OVER             
TOWARDS THE WAUSAU/MARSHFIELD/WISCONSIN RAPIDS CORRIDOR WHERE DEEP              
MOISTURE AND THE COLDEST TEMPS HOLD ON THE LONGEST WITH ALL OTHER               
LOCATIONS UNDER A HALF INCH AWAY FROM LAKE MICHIGAN AND GREEN BAY.              
LOWS IN THE LOWER TO MIDDLE 30S.                                                
TOMORROW...LOW PRESSURE MOVES ACROSS NE WISCONSIN DURING THE MORNING            
BEFORE EXITING EAST INTO MICHIGAN DURING THE PM HOURS.  SHOWERY PRECIP          
WILL CONTINUE FOR MUCH OF THE MORNING...AS A RESULT OF CONVERGENCE              
ALONG A LOW LEVEL TROUGH AND DEFORMATION FLOW ALOFT. PRECIP TYPE                
SHOULD BE SNOW TO START OUT WITH EXCEPT NEAR GREEN BAY AND LAKE                 
MICHIGAN WHERE A MIX WILL BE PRESENT.  MORE RAIN WILL MIX IN BY LATE            
MORNING INTO THE AFTERNOON DUE TO DAYTIME HEATING OVER THE LOWER                
TERRAIN AREAS AWAY FROM THE NORTHERN WISCONSIN PLATEAU. SLUSHY SNOW             
ACCUMULATIONS COULD REACH UP TO A HALF INCH OVER THE WESTERN                    
FORECAST AREA DURING THE MORNING BEFORE SURFACE TEMPS WARM                      
SUBSTANTIALLY ABOVE FREEZING...MELTING ANY SNOW THAT REACHES THE                
GROUND.  BY MID TO LATE AFTERNOON...COLD ADVECTION ENSUES TOWARDS               
THE NORTHWEST FORECAST AREA AND TEMPS WILL BEGIN FALLING.  LAKE                 
EFFECT BANDS MAY START TO IMPACT VILAS COUNTY BUT BELIEVE THIS IS               
MORE OF A PROBLEM FOR LATER PERIODS.  EARLY AFTERNOON HIGHS WILL                
RANGE FROM THE MIDDLE 30S NW TO THE LOWER 40S.                                  
MPC                                                                             
.LONG TERM...SATURDAY NIGHT THROUGH NEXT FRIDAY...MAIN FCST CONCERNS            
INCLUDE LAKE-EFFECT (AND ENHANCED) SNOWFALL OVER NC WI SAT NGT INTO             
SUNDAY...AND TEMPERATURES THROUGHOUT THE PERIOD.                                
COLD NNW FLOW ON THE BACK SIDE OF THE DEPARTING DEEP LOW PRESSURE               
SYSTEM WILL RESULT IN SOME LK-EFFECT SNOW SATURDAY NIGHT. LK-H8                 
DELTA-T`S ARE FCST TO INCREASE TO NEARLY 20 C BY SUNDAY                         
MORNING...SO INSTABILITY WILL BE FAIRLY STG. EXPECT 1-3 INCHES OF               
SNOW TO FALL IN VILAS COUNTY...WITH LESS THAN AN INCH FARTHER                   
SOUTH. ALTHOUGH THE LLVL WIND TRAJECTORIES BECOME A LITTLE TOO                  
WESTERLY TO BE IDEAL FOR PURE LK-EFFECT SNOW ON SUNDAY...SOME LK-               
ENHANCED SNOW IS LIKELY AS A STG S/W TROF MOVES THROUGH N WI. HAVE              
INCREASED POPS ABOVE GUIDANCE ACROSS N WI ON SUNDAY...IN AXIS OF                
DEFORMATION TO THE LEFT OF THE VORT TRACK. ANOTHER INCH OR TWO IS               
PSBL ACROSS THE FAR NORTH...WITH LOCALLY HIGHER AMTS IN NW VILAS                
COUNTY.                                                                         
HAVE KEPT LOW POPS OVER NC WI ON SUNDAY NIGHT AND MONDAY...DUE TO               
CONTINUED COLD NW FLOW. MUCH DRIER AIR IS EXPECTED TO ARRIVE LATER              
ON MONDAY...WHICH SHOULD SHUT DOWN ANY LINGERING LK-EFFECT.                     
HIGH PRESSURE IS FCST TO SETTLE ACROSS THE GREAT LKS RGN FROM MONDAY            
NGT THROUGH THURSDAY...WITH THE NEXT LOW PRESSURE SYSTEM TRACKING               
WELL TO OUR SOUTH. DEPENDING THE THE POSN OF THE SFC HIGH AND                   
ASSOCIATED LLVL WINDS...THERE COULD BE SOME POTENTIAL FOR LK-                   
EFFECT SNOW SHOWERS IN EASTERN WI ON TUES/WED...BUT DETAILS ARE                 
TOO SKETCHY TO ADD A MENTION OF PCPN ATTM.                                      
HAVE ADDED SOME SMALL POPS LATE IN THE WEEK...WITH STG WAA EXPECTED             
ON THU NGT...AND A COLD FRONTAL PASSAGE ON FRIDAY. MOISTURE SHOULD              
BE LIMITED...WITH ZONAL FLOW OFF THE PACIFIC. 12Z ECMWF HAS TRENDED             
WETTER WITH THIS SYSTEM THOUGH...SO WILL NEED TO MONITOR TRENDS                 
OVER THE UPCOMING DAYS.                                                         
ALTHOUGH TEMPERATURES WILL BE MUCH COLDER THAN THEY HAVE BEEN OVER THE          
PAST SEVERAL WEEKS...THEY WILL ACTUALLY BE FAIRLY CLOSE TO NORMAL               
FOR MUCH OF THE PERIOD...WITH MIN TEMPS IN THE 20S AND LOWER 30S...             
AND MAX TEMPS IN THE UPPER 30S AND 40S.

.AVIATION (FOR THE 18Z TAFS)...LOW PRESSURE OVER THE MINNESOTA/IOWA             
BORDER WILL SLOWLY LIFT NORTHEAST OVER THE TAF PERIOD.                          
PRECIPITATION WITHIN MVFR CIGS WILL START OUT AS ALL RAIN                       
INITIALLY...AS IT MOVES INTO AUW/CWA AND RHI BY MID-AFTERNOON                   
BEFORE MIXING WITH SNOW LATE IN THE AFTERNOON. CHANGE-OVER TO ALL               
SNOW WILL ARRIVE AT THESE LOCATIONS MID TO LATE EVENING...AND                   
OCCASIONAL SNOW SHOWERS WILL THEN CONTINUE THROUGH THE REMAINDER                
OF THE TAF PERIOD. SOME IFR CIGS/VSBYS ARE POSSIBLE IN THE HEAVIER              
SNOW SHOWERS. GRB WILL HAVE THE CHANGE-OVER ARRIVE LATER MORE
