HIGH PRESSURE RIDGE BUILDS ACROSS THE REGION TONIGHT.
700 AM EDT FRI MAR 13 2015 CANADIAN HIGH PRESSURE WILL BUILD ACROSS THE REGION TODAY AND WILL AND PASS TO THE SOUTHEAST TONIGHT.
HOWEVER FEEL THIS MOST LIKELY WILL BE FAR A FEW BETWEEN MANY OBSERVATION SITES IN THE HIGHER ELEVATIONS. THE SOUTHERN PASSES WILL HAVE A THREAT OF SLUSHY ROADWAYS IF SHOWERS CAN STAY CONCENTRATED OVER ONE AREA TODAY AND THIS EVENING SO SEE NO REASON TO DROP THE LOW END ADVISORY ATTM. IT APPEARS THE HIGH CLOUD COVER WILL BE THINNING SOME TODAY AS IT PUSHES SOUTH WITH THE ILL- DEFINED CIRCULATION OF THIS STORM.
A COLD FRONT WILL APPROACH FROM THE WEST AND AS IT DOES THE WIND WILL SHIFT TO THE WEST OR SOUTHWEST BETWEEN 08Z AND 12Z. UPPER PV ANOMALY WILL LIFT NORTH THROUGH THE LOWER MISSISSIPPI VALLEY ON FRIDAY THEN SHIFT NORTHEAST INTO THE OHIO VALLEY FRIDAY NIGHT AND SATURDAY.

A 1038 HIGH IN THE NORTHEAST AND 1012 LOW IN THE LOWER MISSISSIPPI VALLEY WILL CONTINUE WITH THE INCREASE OF THE GULF MOISTURE.
1057 AM CST Sat Jan 17 2015 A cold front will move through the region this afternoon and while this won't be a huge temperature altering event, it does make the forecast a little more challenging for several reasons.
900 AM PST SAT JAN 17 2015 ABOVE NORMAL TEMPERATURES WILL CONTINUE TODAY DUE TO HIGH PRESSURE ALOFT AND OFFSHORE BREEZES.
THANKS TO A TROUGH PUSHING INTO THE NORTHWEST STATES. BUT TEMPERATURES WILL REMAIN ABOVE NORMAL WITH THE RIDGING ALOFT PERSISTING. HIGH CLOUDS SHOULD PEEL OFF THE AFOREMENTIONED TROUGH TO THE NORTH.
348 PM CST SAT JAN 17 2015 UPPER LEVEL PV ANOMALY PASSING ACROSS EASTERN NEBRASKA AND WEST CENTRAL IOWA WITH SUBSIDENCE REGION OF THE SYSTEM JUST SOUTH OF THE REGION AND THAT HAS BEEN THE AREA WITH THE HIGHEST WIND GUSTS TODAY.

1044 AM CST SAT JAN 17 2015 AMPLE WARMING WELL UNDERWAY THIS MORNING AS 10AM TEMPERATURES ARE ALREADY NEAR 50 DEGREES OR ABOVE AFTER EARLIER LOWS NEAR FREEZING IN MANY LOCATIONS. PRESSURE GRADIENT ACROSS THE SOUTHERN PLAINS/LOWER MISS VALLEY WILL STRENGTHEN TODAY AHEAD OF A COLD FRONT. THERE MAY BE A NARROW BAND OF 5KFT CLOUDS ASSOCIATED WITH THE COLD FRONT ITSELF BUT ANY CLOUDS OR CEILINGS AT THIS HEIGHT WOULD BE BRIEF. WEAK COLD FRONT MOVG INTO KS WILL BRING LITTLE CHANGE TO WX ASIDE FROM SOME UPPER LVL CLOUDS SAT NIGHT INTO SUNDAY. SOUTHERN STREAM JET TO BRING MOSTLY MID LVL MOISTURE BACK INTO AREA LATER IN WEEK AS ANOTHER WEAK COLD FRONT MOVES SOUTH THRU AREA AND PHASES WITH JET.
ENHANCING THE WARMING TREND WILL BE A LAYER OF VERY DRY MID-LEVEL AIR MIXING DOWN AND S/SW WINDS IN THE LOW LEVELS TO ADD A SLIGHT DOWN-SLOPING COMPONENT. WITH THE EASTWARD PASSING OF THE ELEVATED TROUGH. SO MINS MAY ONLY FALL INTO THE LOWER 40S ALONG AND EAST OF I-35.
WHILE COLD FRONT SWEEPS THROUGH THE MIDWEST. UPPER LEVEL ANALYSIS SHOWS RIDGE OVER THE WESTERN CONUS. WITH TROUGH MOVING INTO THE MIDWEST. SKIES HAVE CLEARED WITH THE DEPARTURE OF THE TROUGH. QUIET WEATHER WILL CONTINUE AS TROUGH CONTINUES ITS EASTWARD PROGRESSION. WARM FRONT LIFTS THROUGH THE AREA AS LIGHT PRECIPITATION STARTS TO DEVELOP PRIMARILY OVER THE NORTHWEST SPREADING TOWARDS THE NORTH CENTRAL THROUGH THE AFTERNOON WITH THE APPROACHING TROUGH. THIS WILL BRING A CONCERN FOR FREEZING RAIN OVER PORTIONS OF THE AREA. PARTICULARLY TOWARDS THE NORTH WHERE COOLER SURFACE TEMPS ARE EXPECTED.
216 PM EST SAT JAN 17 2015 UPPER AIR PATTERN CONSISTS OF A 500 MB TROUGH MOVING INTO THE UPPER MISSISSIPPI RIVER VALLEY THIS MORNING. THIS TROUGH MOVES INTO THE UPPER GREAT LAKES BY THIS EVENING AND MOVES THROUGH TONIGHT AND INTO THE LOWER GREAT LAKES ON SUN. SYSTEM SNOW AND FREEZING DRIZZLE WILL LAST INTO THIS EVENING OVER THE EASTERN CWA. KEPT THE HIGHEST POPS IN THE NORTHWESTERLY LAKE EFFECT SNOW BELTS.

HIGHS TODAY WILL GENERALLY BE IN THE LOWER 40S. 5 G/KG PER RUC/NAM PRECEDENT TO FROPA/TROF PASSAGE OF HIGH BELTED NRN UPR GRTLKS. SHARP MID LEVEL TROUGH OVER THE AREA TO START GRADUALLY EXITS EAST ON SUNDAY WITH ADEQUATE MOISTURE DEPTH/CYCLONIC FLOW/STEEPENING LOW LEVEL LAPSE RATES WITHIN CAA REGIME TO SUPPORT A FEW SNOW SHOWERS THROUGH MID AFTN (ESPECIALLY NORTH GIVEN SOME LAKE ENHANCEMENT).
A DRY COLD FRONT PASSING FROM NORTHWEST TO SOUTHEAST THROUGH THE AREA OVERNIGHT WILL BE ACCOMPANIED BY A BAND OF LOWER CLOUDS - RESULTING IN A FEW HOURS OF CIGS MOSTLY IN THE 2000-4000 FT RANGE IN ROUGHLY THE 04-08Z TIME FRAME. ANOTHER UPPER LEVEL TROUGH WILL FORCE A DRY COLD FRONT INTO AND THROUGH THE FORECAST AREA LATE TONIGHT INTO EARLY SUNDAY MORNING.
231 PM EST SAT JAN 17 2015 HIGH PRESSURE OVER THE REGION WILL MOVE OFFSHORE THIS AFTERNOON. AN UPPER LEVEL DISTURBANCE AND COLD FRONT CROSSING THE AREA TONIGHT INTO SUNDAY WILL BRING ANOTHER CHANCE FOR SHOWERS. HIGH PRESSURE CONTINUES TO MOVE NORTHEASTWARD AWAY FROM THE REGION AS MOISTURE MOVES INTO THE COASTAL COUNTIES. WEAK LOW PRESSURE WILL DEVELOP ALONG THE COAST THIS EVENING AND MOVE NORTHWARD OVERNIGHT. THE MAIN UPPER TROUGH WILL CONTINUE TO DEEPEN AND MOVE THROUGH THE REGION DURING THE DAY.
The short wave trof currently moving through the Northern Rockies will dig southeastward and amplify over the next 24 hours producing large height falls across the region this afternoon and evening as it moves into and through the MS Valley. The attendant cold front now evident in the Plains will move through the area during the later half of this afternoon and evening and be accompanied by decent cold advection. Ahead of this front however a very favorable pattern will exist for unusually warm temperatures, including veering gusty southwesterly winds and a prominent low level thermal ridge. The aforementioned upper trof will be accompanied by weak large scale forcing and ascent, however limited low-mid level moisture should preclude any precipitation until perhaps the system gets to the east of the CWA early this evening.
1020 AM MST SAT JAN 17 2015 16Z SURFACE ANALYSIS SHOWED COLD FRONT WELL SOUTHEAST OF CWA WITH MODERATELY TIGHT GRADIENT OVER THE SD PLAINS. TODAY THROUGH SUNDAY NIGHT CURRENT SURFACE MAP SHOWS COLD FRONT MOVING THROUGH WESTERN SOUTH DAKOTA.
1126 AM CST Sat Jan 17 2015 It will be a mild and breezy day today as a cold front will approach the area late this afternoon. The upper level flow shifts again by mid week with a trough digging across the Midwest and Great Lakes Region.
WENT WARMER SUN WITH GOOD INSOLATION AND DOWNSLOPE FLOW AS WINDS BACK DURING THE DAY. THERE IS MORE UNCERTAINTY IN HIGHS IN SOUTHEAST KS WHERE ECMWF IS A BIT COOLER.
952 AM MST SAT JAN 17 2015 16Z SURFACE ANALYSIS SHOWED COLD FRONT WELL SOUTHEAST OF CWA WITH MODERATELY TIGHT GRADIENT OVER THE SD PLAINS. TODAY THROUGH SUNDAY NIGHT CURRENT SURFACE MAP SHOWS COLD FRONT MOVING THROUGH WESTERN SOUTH DAKOTA.
HIGH PRESSURE WILL CONTINUE TO SLIDE EAST. TRENDING TOWARDS NORMAL FOR THE HIGHS TOMORROW. THE EARLY PART OF THE FORECAST RELATIVELY CLEAR WITH A DEPARTING UPPER TROUGH SUNDAY NIGHT. MOISTURE DEPTH AND EXPANSE WILL BE ON THE DECREASE THROUGH THE NIGHT BUT SHOULD BE ENOUGH FOR A COUPLE SNOW SHOWERS IN THE HIGHER TERRAIN ACROSS SOUTHWEST VIRGINIA AND NORTHEAST TENNESSEE.
155 PM PST SAT JAN 17 2015 HIGH PRESSURE WILL REMAIN OVER THE REGION FOR THE NEXT SEVERAL DAYS. SATELLITE LOOPS SHOW HIGH CLOUDS AHEAD OF AN APPROACHING UPPER-LEVEL TROUGH CONTINUING TO MOVE TOWARD CENTRAL CALIFORNIA.
A COLD FRONT WILL MOVE ACROSS THE REGION OVERNIGHT WITH AREAS OF FOG DEVELOPING AHEAD OF THE BOUNDARY. A WEAK COLD FRONT WILL MOVE ACROSS THE AREA DURING THE OVERNIGHT. A SHORT WAVE TROUGH WILL PRODUCE SOME HIGH CLOUDS. ON SUNDAY A WEAK COLD FRONT WILL MOVE THROUGH.
UPGRADED THE HIGH WIND WATCH FOR THE CODY FOOTHILLS TO A WARNING AND ISSUED HIGH WIND WARNING FOR PORTIONS OF SOUTHERN FREMONT COUNTY AND NATRONA COUNTY. FLAT RIDGING ACROSS THE WEST WITH ROBUST MOISTURE OF EARLIER IN THE DAY BEING REPLACED BY MORE MODEST AMOUNTS WITH LIGHT TO OCCASIONALLY MODERATE SNOW STILL STREAMING/FALLING ACROSS THE WRN MOUNTAINS OF WY.
THE NAM IS WARMER THAN THE GFS WITH THIS SYSTEM. THINK TEMPERATURES WILL BE ON THE WARMER SIDE AND WITH UNCERTAINTY.
MID LEVEL CLOUDS ARE MOVING THROUGH THE NRN CWA ATTM DUE TO SIGNIFICANT MID LEVEL WARMING AS RIDGE AXIS MOVES EAST OF FA. COOL CANADIAN HIGH PRESSURE WILL BUILD OVER THE REGION TODAY, BRINGING FAIR WEATHER, LIGHT WINDS, AND SLIGHTLY BELOW NORMAL TEMPERATURES. A SURFACE TROF WILL MOVE THROUGH NY/PA ON SUNDAY. JUDGING BY THE SOUNDINGS, MOST OF THE HIGH RH IS CONFINED TO THE COLD LOWER ATMOSPHERE, WITH A WARM LAYER ABOVE THE MOISTURE.
AMPLIFIED MID TO UPPER LEVEL TROUGHING. BY SUNDAY THE CWA WILL BE ON THE WESTERN SIDE OF THE TROUGH WITH LOW- LEVEL COLD THERMAL ADVECTION MAXIMIZED DURING THE MORNING TO EARLY AFTERNOON.
COLD FRONT PASSES SUNDAY BRINGING COOLER TEMPERATURES. HIGH PRESSURE IS FIRMLY IN PLACE FOR SATURDAY OVER NORTH CENTRAL WEST VIRGINIA. SOUTHERLY FLOW WILL CREATE DOWN SLOPING WINDS AND WARM AIR ADVECTION HAVE RESULTED IN QUITE A WARM UP FOR TODAY WITH HIGHS IN THE 50S FOR THE LOWLANDS. A COLD FRONT PASSES THROUGH SUNDAY. GUSTY WINDS ARE LIKELY ALONG AND BEHIND THE COLD FRONT ON SUNDAY. A ZONAL FLOW ALOFT PATTERN IS FORECAST BY THE MODELS WITH UPPER DISTURBANCES AND ASSOCIATED COLD FRONTS ZIPPING ACROSS THE AREA. ONE SUCH COLD FRONT COMES ACROSS DURING SUNDAY. IN THE HIGHER ELEVATIONS OF THE NORTHERN AND CENTRAL MOUNTAINS. BOUNDARY LAYER COLDER AIR DOES ARRIVE TO CHANGE RAIN SHOWERS TO SNOW SHOWERS IN THE LOW LANDS BEFORE ENDING.
358 PM CST SAT JAN 17 2015 HIGH PRESSURE WILL CONTINUE TO MOVE TO THE EAST AS A COLD FRONT WILL MOVE THROUGH THE AREA LATE TONIGHT INTO SUNDAY MORNING.
A NORTH NORTHWESTERLY FLOW WILL BACK MORE TO THE WEST OVERNIGHT AS AN UPPER RIDGE AXIS MOVES EAST ACROSS THE CENTRAL AND NORTHERN ROCKIES. AS THE DOWNSLOPE FLOW IMPROVES A TROUGH OF LOW PRESSURE WILL BEGIN TO DEVELOP AT THE SURFACE ACROSS EASTERN COLORADO AFTER MIDNIGHT. GIVEN THESE WIND SPEEDS OVERNIGHT ALONG WITH DOWNSLOPE FLOW WILL FAVOR THE WARMER GUIDANCE FOR OVERNIGHT LOWS.
A WEAK COLD FRONT WILL PUSH THROUGH THE REGION TONIGHT.
AN ENHANCED PRESSURE GRADIENT AHEAD OF A WEAK COLD FRONT WILL ALLOW FOR SOUTH WINDS AROUND 10 TO 15 KNOTS AND GUSTY THIS AFTERNOON.
MORNING ANALYSES INDICATE A WEAK WEDGE RIDGE TO THE EAST, COUPLED WITH INCREASING SOUTHWESTERLY FLOW AHEAD OF A COLD FRONT EXTENDING ALONG THE I-35 CORRIDOR. CIG VALUES HOWEVER WILL BE REDUCED INTO THE LOWER VFR RANGE LATE IN THE PERIOD. RSB /ISSUED 336 AM CST SAT JAN 17 2015/ AN UPPER LEVEL TROUGH. THE COLD FRONT SHOULD PASS THROUGH THE AREA BY DAYBREAK ON SUNDAY. UPPER LEVEL RIDGING WILL BUILD IN BEHIND THIS TROUGH. WITH HIGH PRESSURE DEVELOPING ALONG THE GULF COAST. THE NORTHERLY WINDS BEHIND THE WEAK COLD FRONT WILL QUICKLY SHIFT TO THE SOUTH BY SUNDAY NIGHT.
HIGH PRESSURE WILL REMAIN OVER THE REGION FOR THE NEXT SEVERAL DAYS. THE DENSEST FOG APPEARS TO BE ALONG AND WEST OF THE HIGHWAY 99 CORRIDOR FROM SOUTHERN FRESNO TO NORTHERN KERN COUNTY. FORECAST CONTINUES TO BE A CHALLENGE WITH THE LOW STRATUS MAKING A RETURN TONIGHT AND INHIBITING DENSE FOG FORMATION.
FOLLOWED BY UNSETTLED WEATHER ON SUNDAY AS A COLD FRONT PASSES ACROSS THE REGION. THE TWO AFOREMENTIONED AREAS ARE THE SOUTHERN REACHES OF THE CWA AS WELL AS AREAS GENERALLY FROM LATROBE TO MORGANTOWN WEST OF THE CHESTNUT RIDGE. WITH WARMER NUMBERS SEEMINGLY LIKELY TO PREVAIL. AREAS TO THE NORTH AND EVENTUALLY WEST WILL LIKELY MIX WITH SNOW AS THE COLD FRONT BEARS DOWN ON THE AREA. FRIES WITH THE FRONTAL BOUNDARY AND ASSOCIATED MID LEVEL TROUGH AXIS EAST OF THE AREA BY SUNDAY EVENING.
252 PM CST SAT JAN 17 2015 COLD FRONT CURRENTLY SLIDING THROUGH EASTERN OKLAHOMA IS NEAR A KJLN TO KGLE LINE AT THIS HOUR. THIS COLD FRONT WILL BE NOTHING BUT A DISTANT MEMORY ON SUNDAY AS EVEN WARMER TEMPERATURES ARE ANTICIPATED. THE MAIN CONCERN ON SUNDAY WILL BE FIRE WEATHER WITH WINDS EXPECTED TO PICK UP OUT OF THE SOUTHWEST AS A WEAK SURFACE TROF MOVES INTO CENTRAL OKLAHOMA.
WINDS BECOME WEST BEHIND COLD FRONT AT 10 KTS. THE TRAILING COLD FRONT IS FORECAST TO MOVE ACROSS SOUTH FLORIDA SUNDAY AFTERNOON.
Locally heavy snow is possible over the higher mountains. We also expanded to areal coverage of light freezing rain. The GFS was the cooler and more correct guidance. 20Z and 22Z Saturday marks the general beginning of light precipitation as the leading edge of a wet winter weather low pressure system with a warm trajectory of approach from the southwest spreads snow from southwest to northeast initially. Warming with this system passage allows for a transition to a wintry mix which includes some freezing rain at times. Wind shear later tonight after 04Z Sunday for KPUW remains reasonable given the trend for the lower level surface winds to remain southeast while upper level winds veer to the southwest with height.
BOUNDARY LAYER WINDS INCREASE THROUGH THE AFTERNOON AHEAD OF COLD FRONT APPROACHING THE MISSISSIPPI VALLEY. 12Z SOUNDING SHOWED THAT TEMPS HAD WARMED QUITE A BIT IN THE LOW LEVELS OVER THE LAST 24 HRS, AVERAGING SOME 4 TO 6 DEGS C.
THE HIGHEST POPS I CAN GO AT ANY TIME IS JUST 20 TO 30 PERCENT.
317 PM CST SAT JAN 17 2015 A COLD FRONT IS MOVING THROUGH THE REGION THIS AFTERNOON BUT TEMPERATURES CONTINUE TO RISE BEHIND THIS FRONT.
DEEPENING MID LEVEL TROUGH CLEARS FA TO THE EAST TONIGHT.
FLOW PATTERN ALOFT WILL BE SOMEWHAT PROGRESSIVE BUT THERE WILL REMAIN A TENDENCY FOR RIDGING FROM OFF THE CALIFORNIA COAST UP INTO WESTERN CANADA. A COLD FRONT WAS PUSHING THROUGH THE REGION. GENERALLY WENT AROUND OR ABOVE THE WARMER GFS MOS GUIDANCE FOR HIGHS THE NEXT FEW DAYS. WITH A RIDGE DEVELOPING IN WESTERN CANADA.
A WARM FRONT IS EAST OF THE JAMES RIVER VALLEY. WITH THE COLD FRONT EXTENDING FROM NEAR RUGBY TO EAST OF BISMARCK. BEHIND THE COLD FRONT NORTHWEST WINDS WERE MAINLY 25 TO 30 MPH WITH GUSTS TO 35-40 MPH.
/ISSUED 333 AM CST SAT JAN 17 2015/ COLD FRONT CURRENTLY FROM CENTRAL KS THROUGH NW OK WILL SWEEP THROUGH THE FORECAST AREA TODAY WITH MINIMAL EFFECT ON HIGH TEMPS.
255 PM CST Sat Jan 17 2015 Energetic mid level trof moving ESE from the Plains and across the region tonight, coupled with a surface frontal passage, will result in increased cloud cover.
WINDS WILL SHIFT TO THE NORTH ACROSS THE EDWARDS PLATEAU/WEST HILL COUNTRY AS A WEAK COLD FRONT PUSHES ACROSS THE AREA. ENHANCING THE WARMING TREND WILL BE A LAYER OF VERY DRY MID-LEVEL AIR MIXING DOWN AND S/SW WINDS IN THE LOW LEVELS TO ADD A SLIGHT DOWN-SLOPING COMPONENT. WITH THE EASTWARD PASSING OF THE ELEVATED TROUGH. SO MINS MAY ONLY FALL INTO THE LOWER 40S ALONG AND EAST OF I-35.
225 PM EST SAT JAN 17 2015 MAIN FOCUS ON SHORT TERM WILL BE WITH ANY PRECIP CHANCES ACROSS NORTH GEORGIA LATE TONIGHT INTO SUNDAY MORNING WITH AN APPROACHING UPPER TROUGH AND TRANSLATED SFC COLD FRONT. GENERAL CONSENSUS OF GUIDANCE INDICATES THAT WHILE THE TROUGH AMPLIFIES AND DIGS SOUTHWARD. PROGGED THERMAL PROFILES HAVE SOME DISCREPANCIES WITH THE WARMER NAM INDICATING MAINLY A LIGHT RAIN. SFC TEMPS WERE MAINLY ABOVE FREEZING FOR OVERNIGHT LOWS TONIGHT THOUGH SOME SPOTTY 31-32 DEG ARE POSSIBLE IN THE NE.
A WEAK COLD FRONT WILL APPROACH FROM THE WEST TODAY AND EARLY TONIGHT THEN MOVE ACROSS AND EAST OF THE ALL TERMINAL SITES BY EARLY SUN MORNING. MOSTLY SUNNY CONDITIONS CAN BE EXPECTED WITH HIGHS WARMING INTO THE LOW 60S. A COLD FRONT WILL APPROACH THE AREA THIS EVENING AND MOVE QUICKLY EAST OF THE AREA BY SUNDAY MORNING.
DOWNLSOPING SURFACE WINDS AND DIMINISHING SNOWCOVER WILL ALLOW TEMPERATURES TO WARM INTO THE LOWER 60S ACROSS MOST OF THE AREA SUNDAY AFTERNOON.
SKIES RANGE FROM MOSTLY SUNNY TO MOSTLY CLOUDY WITH TEMPERATURES IN THE LOWER TO MID 70S. LOCAL RADARS ARE DETECTING AN AREA OF RAIN WITH EMBEDDED SHOWERS ON THE OUTER STRAITS BEYOND 20 NM SOUTHEAST OF THE LOWER AND MIDDLE KEYS. A WEAK WARM FRONT ASSOCIATED WITH THE AFOREMENTIONED SHOWERS IS DRAPED FROM THE CENTRAL COAST OF CUBA NORTHEASTWARD INTO THE OUTER STRAITS. WITH A LARGE REGION OF HIGH PRESSURE ALIGNED ALONG THE EASTERN SEABOARD AND THE FLORIDA EAST COAST.
BUT PUSHES THE FOG INTO THE LOWER PORTION OF THE SAN JUAN RIVER BASIN AND MONUMENT VALLEY.
A sharp yet progressive 500mb trough associated with the northern branch of the jet will move across the Commonwealth Sunday morning. This trough is starved of moisture, and only some light showers or sprinkles are anticipated for southern Indiana and northern Kentucky, mainly east of Interstate 65. In fact our overnight lows through early Sunday will stay above freezing. However modified Pacific air behind this front will bring only a modest cooldown for Sunday, with highs ranging from near 50 to the lower 40s across the Bluegrass. Modest warm air advection will keep temperatures from falling much below freezing.
A COLD FRONT WAS ANALYZED TO BE EXTENDING SOUTHWEST FROM NEAR MADISON WISCONSIN. THE SHORT TERM MODELS PROGRESSIVELY MOVING THE COLD FRONT THROUGH THE LOWER OHIO AND TENNESSEE VALLEY REGION BY 12Z SUNDAY.
341 PM CST SAT JAN 17 2015 UNSEASONABLY WARMER DAYTIME TEMPERATURES WILL CONTINUE OVER THE NEXT SEVERAL DAYS DESPITE A WEAK COLD FRONT TRANSITIONING ACROSS THE REGION LATER THIS EVENING WITH LITTLE MORE THAN A WIND SHIFT OCCURRING WITH FROPA.
305 PM EST SAT JAN 17 2015 A QUICK RETURN TO EASTERLY FLOW TODAY HAS ALLOWED TEMPERATURES TO WARM IN THE LOW/MID 70S THIS AFTERNOON. HIGH PRESSURE ALONG THE EASTERN SEABOARD WILL MOVE EASTWARD TONIGHT AS A TROUGH MOVES INTO THE OHIO VALLEY. A TROUGH ACROSS THE OHIO VALLEY SUNDAY MORNING WILL PUSH EASTWARD. AND AN INVERTED TROUGH OVER FLORIDA WILL PUSH SOUTHWARD AS A COLD FRONT. THE COLD FRONT WILL PUSH THROUGH SOUTH FLORIDA SUNDAY AFTERNOON. HIGHS WILL REACH THE LOWER 70S NORTHWEST AND GULF COAST TO THE UPPER 70S SOUTHEAST.
1214 PM EST SAT JAN 17 2015 HIGH PRESSURE OVER THE REGION WILL MOVE OFFSHORE THIS AFTERNOON. AN UPPER LEVEL DISTURBANCE AND COLD FRONT CROSSING THE AREA TONIGHT INTO SUNDAY WILL BRING ANOTHER CHANCE FOR SHOWERS. HIGH PRESSURE WILL MOVE AWAY FROM THE REGION THIS AFTERNOON AS WEAK LOW PRESSURE BEGINNING TO DEVELOP ALONG THE COAST PUSHES MOISTURE ONSHORE AND A WEAK FRONT APPROACHES FROM THE WEST. THE MAIN UPPER TROUGH DEEPENS AND CROSSES THE REGION THROUGH THE DAY SUNDAY. TEMPERATURES SUNDAY MAY ACTUALLY BE WARMER GIVEN DOWN SLOPE FLOW.
MORNING ANALYSES INDICATE A WEAK WEDGE RIDGE TO THE EAST, COUPLED WITH INCREASING SOUTHWESTERLY FLOW AHEAD OF A COLD FRONT EXTENDING ALONG THE I-35 CORRIDOR. WITH A BRIEF PERIOD OF LOWER (4-5KFT) CLOUDS IN THE 07-08 TO 10-11Z TIME FRAME AS A WEAK COLD FRONT MOVES THROUGH BOTH TERMINALS.
LOW PRESSURE WAS LOCATED OVER NE ND TODAY. AN ATTENDANT COLD FRONT EXTENDED FROM THE CENTER OF THE LOW THRU GRAND ISLAND NE. MAIN FORECAST CONCERN FOR THE EXTENDED IS A LOW PRESSURE SYSTEM MOVING TO THE NORTH OF THE AREA TODAY. THIS SYSTEM WILL USHER THRU A COLD FRONT TODAY. A LOW ASSOCIATED WITH THE NORTHERN PART OF THE TROF WILL MOVE THROUGH THE AREA TODAY. HAD TO INCREASE TEMPS FOR THE HIGHS TODAY. THINK THAT WE WILL HAVE JUST AS WARM IF NOT WARMER TEMPS TODAY. EVEN WITH THE HIGH LEVEL CLOUDS. WE MAY SEE THEM MELT IN THE LOW LEVELS.
A MIX OF SNOW AND FREEZING RAIN TO IMPACT MOUNTAIN PASSES AND. Northwest Montana valleys will continue to have a particularly difficult time of warming above freezing ahead of the moisture swath. Consequently, the relatively warm moisture aloft will fall as snow and freezing rain at valley elevations of northwest Montana.
THIS WAVE WAS RESPONSIBLE FOR AN AREA OF LIGHT FREEZING DRIZZLE OVER NORTHWEST MINNESOTA. AND AS A RESULT ISSUED A FREEZING RAIN ADVISORY FOR PORTIONS OF THE FORECAST AREA.
348 PM CST SAT JAN 17 2015 (Tonight and Sunday) The cold front is along the Interstate 10 corridor at mid-afternoon, and moving south.
and the high wind watch for Sunday looks on track.
THINK TEMPERATURES WILL RISE A FEW DEGREES WARMER THAN PREVIOUSLY FORECAST. A COLD FRONT WILL MOVE THROUGH THE AREA TODAY WITH GUSTY NORTH WINDS BEHIND THE FRONT. /ISSUED 434 AM CST SAT JAN 17 2015/ COLD FRONT IS MOVING THROUGH SOUTHWEST KANSAS AND THE CENTRAL OKLAHOMA PANHANDLE RIGHT NOW AND WILL BE MOVING THROUGH THE FORECAST AREA TODAY.
THE STRONGEST PRESSURE GRADIENT IS BEING OBSERVED ACROSS CENTRAL AND EASTERN NEBRASKA WITH HIGH PRESSURE SEEN OVER THE PANHANDLE ALLOWING THE GRADIENT TO RELAX SLIGHTLY. A PACIFIC COLD FRONT WILL SWEEP THE FCST AREA THIS MORNING. THE MODELS CONTINUE A ROBUST NORTHWEST WIND AT H850MB 20 TO 40 KT MOST OF THE NIGHT AND ANOTHER THERMAL RIDGE WILL BUILD ACROSS THE PANHANDLE WITH H850MB TEMPERATURES RISING TOWARD 5C IN THE WEST.
THROUGH SUNDAY LIGHT RAIN NOW JUST EAST OF THE COTEAU SO FREEZING RAIN MENTION WILL CONTINUE THROUGH 09-10Z. HEADLINES EXTENDED THOUGH AS WARMER AIR IS SLOW TO PROGRESS INTO THE JAMES VALLEY. GOOD MIXING CONDITIONS WILL CONTINUE INTO SUNDAY WITH A WEAK TROF MOVING THROUGH.
AN UPPER LEVEL TROUGH WILL BRING A DRY COLD FRONT THROUGH THE REGION LATER TONIGHT.
A COLD FRONT HAS MOVED SOUTHEASTWARD BRINGING A WIND SHIFT TO KGUY AND KDHT EARLY THIS MORNING AND WILL REACH KAMA BY AROUND 13Z. /ISSUED 403 AM CST SAT JAN 17 2015/ COLD FRONT TO MOVE THROUGH THE PANHANDLES THIS MORNING BY 18Z TODAY.
Low pressure riding along the Canadian border will move into the Great Lakes by this evening. As it does, it drops down the bulk moisture over the High plains, resulting in increasingly cloudy skies for us. Pops drop off after midnight as the primary Long Wave trof moves just east of our area.
1258 PM EST SAT JAN 17 2015 HIGH PRESSURE WILL BUILD OVER THE AREA TODAY THEN MOVE TO THE EAST TONIGHT.
ON SUNDAY AN UPPER LEVEL TROF WILL APPROACH THE REGION AND GO SLIGHTLY NEGATIVE TILT AS THE DAY PROGRESSES. EARLY SUNDAY MORNING AROUND DAYBREAK IF PRECIP OCCURS OVER THE FAR SE A LIGHT MIX OF SLEET AND FREEZING RAIN LOOKS MOST LIKELY. IF THIS DOES OCCUR THE PRECIP WILL CHANGE QUICKLY TO JUST RAIN BY MID MORNING AS SFC TEMPS WARM ABOVE FREEZING.
THE MAIN FOCUS IS ON WIND BEHIND A COLD FRONT PASSING THROUGH OVERNIGHT. ASSOCIATED WITH A DIGGING MID-UPPER LEVEL TROUGH PASSING THROUGH.
941 AM PST SAT JAN 17 2015 ABOVE NORMAL TEMPERATURES WILL CONTINUE TODAY DUE TO HIGH PRESSURE ALOFT AND OFFSHORE BREEZES.
A "cold front" (more of a wind shift) moved across the Permian Basin this morning and is moving thru the Trans Pecos this aftn.
