TONIGHT EXPECT MOSTLY CLEAR TO CLEAR SKIES ACROSS EASTERN KENTUCKY WITH POTENTIAL FOR RIDGE/VALLEY SPLITS IN TEMPS. THE ONLY CONCERN THAT WE HAVE SEEN AVIATION WISE HAS BEEN THE WINDS INCREASING OUT OF THE WEST IN THE WAKE OF A COLD FRONT MOVING ACROSS THE REGION. HIGH PRESSURE WILL BRING VFR CIGS FOR THE REMAINDER OF THE PERIOD WITH LIGHT WINDS.
TEMPERATURES WERE A BIT WARMER THAN FORECAST IN THE SOUTHEAST AND THEIR RISE SHOULD BE TEMPERED SOME ONCE THE THICKER MID/HIGH CLOUDS ARRIVE.
1154 AM MDT TUE MAY 12 2015 04Z WATER VAPOR IMAGERY/RUC ANALYSIS INDICATES SHORT WAVE RIDGING IN PLACE ACROSS THE NORTHERN ROCKIES WITH STRONG CLOSED CIRCULATION MOVING SOUTH ACROSS THE WEST COAST.
AS THE LOW SPINS AWAY. ANTICIPATE HIGH ENOUGH CAPE VALUES WILL LINGER OVER THE REGION TO MAINTAIN THE POTENTIAL FOR ISOLD SEVERE STORMS AS THE PVA ALOFT AND THE DAYTIME HEATING INCREASE THE LOW LEVEL CONVERGENCE.
FAST NORTHWEST FLOW WILL CONTINUE ACROSS THE SANDHILLS REGION OF NEBRASKA AS A TROUGH DIGS SOUTH OVER THE GREAT LAKES. MCPHERSON AND LOGAN COUNTIES WERE ADDED TO THE HIGH WIND WARNING THIS AFTERNOON BASED OFF OF HIGH WIND CRITERIA FROM KTIF AND KBBW. TEMPERATURES TONIGHT WERE TRENDED WARMER THAN GUIDANCE AS THE ATMOSPHERE SHOULD STRUGGLE TO DECOUPLE WITH THE EXPECTED GUSTY CONDITIONS. FOR MONDAY HIGHS WILL BE A FEW DEGREES COOLER THAN SUNDAY AS CAA FUNNELS SOUTH FROM THE NORTHERN PLAINS. AS THE UPPER RIDGE IN THE WEST BREAKS DOWN.
THIS EVENING THROUGH MONDAY NIGHT 20Z UPPER AIR ANALYSIS REVEALS THE CWA "SQUEEZED" BETWEEN A STRONG UPPER LEVEL LOW AND RIDGE OVER MINNESOTA AND THE WESTERN CONUS. WITH THE HIGHEST OCCURRING IN WASTA AND SCENIC AT 78MPH. THE UPPER LEVEL LOW OVER MINNESOTA/WISCONSIN BEGINS TO DIG SOUTHEASTWARD INTO THE EASTERN CONUS AND A HIGHLY AMPLIFIED UPPER LEVEL RIDGE BEGINS TO APPROACH THE CWA. CLOUDS WILL INCREASE MONDAY NIGHT ACROSS EASTERN PORTIONS OF THE CWA AS A BACKDOOR COLD FRONT WORKS ITS WAY INTO THE REGION.
HIGH PRESSURE IS BUILDING ALOFT AND WINDS WILL GENERALLY REMAIN LIGHT THROUGH THE NIGHT. HIGH PRESSURE IS BUILDING ALOFT AND THE AIRMASS WILL WARM AND DRY.
WITH LITTLE MOVEMENT FROM THE RIDGE OVER THE GREAT BASIN UNTIL THE END OF THE WEEK. THE ONLY CHANGE HAS BEEN TO DELAY THE PASSAGE OF THE SHORT WAVE TROUGH THIS COMING WEEKEND ONE MORE DAY.
Mostly clear skies this evening over NorCal under strong high pressure ridge. Strong high pressure along with offshore flow will result in very mild temperatures across the region the next several days.
1228 AM EST MON FEB 8 2016 SCATTERED LIGHT RAIN IS POSSIBLE THROUGH THE EARLY PORTIONS OF THE OVERNIGHT HOURS MAINLY EAST OF INTERSTATE 69 AS A COLD FRONTAL BOUNDARY TRACKS ACROSS THE AREA.
A prefrontal trough has veered winds to the west and wnw this afternoon with temperatures leveling off in the lower-middle 50s. The high amplitude northwest upper level flow pattern will modify a bit as the week goes on. Cold front pushed through during the past hour at SGF and northwest winds kicked up into the 20 to 30 kt range.
Winds WSW around 10 mph ahead of the cold front. Long wave trof digging in over the Midwest, with good representation on sat imagery this morning. The deep trof over the eastern half of the country will be the driving force through the end of the forecast period. Variations and challenges in the forecast revolve around subtle but significant nuances between models in handling the trof.
422 AM EST MON FEB 8 2016 A COLD FRONT IS APPROACHING THE REGION EARLY THIS MORNING. RESULTING IN SOME MODERATE TO HEAVY SNOWFALL OVER THE EAST TENNESSEE MOUNTAINS THANKS TO THE SUBFREEZING AIR THERE. THE MAIN WEATHER STORY WILL REMAIN THE DEVELOPING LONG-WAVE TROUGH ACROSS THE EASTERN HALF OF THE NATION.
ESPECIALLY ACROSS SOUTH CENTRAL KS WHERE HIGHS MAY CLIMB INTO THE LOWER 50S. A COLD FRONT MAY BACK ACROSS THE AREA LATE IN THE WEEK BUT THE BULK OF COLDER AIR IS EXPECTED TO REMAIN EAST OF THE FORECAST AREA. WITH KCNU HAVING THE HIGHEST LIKELIHOOD OF SEEING LOW END VFR CEILINGS.
A COLD FRONT EXTENDS ACRS CNTL ARK SW INTO CNTL TX. THE COLD FRONT WILL MOVE THROUGH THE AREA EARLY MONDAY MORNING. THIS WILL LIKELY BE BRIEF AS A COLD FRONT SWEEPS INTO THE AREA TOWARDS THE EARLY MORNING HOURS BRINGING THE WINDS AROUND TO THE NORTHWEST. A DRY COLD FRONT WILL SWEEP DOWN ACROSS OUR REGION OVERNIGHT.
306 AM CST MON FEB 8 2016 UPPER LOW NOW OVER THE WRN GREAT LAKES WITH TWO CDFNTS HEADING OUR WAY.
338 AM CST MON FEB 8 2016 (Today and Tonight) Post-frontal temperatures today will see afternoon highs 5-10 degrees cooler than yesterday. As winds begin to die around sunrise, good radiational cooling conditions will see temperatures drop to the lower 30s across the Big Country and upper 20s over the remainder of the forecast area.
337 AM CST MON FEB 8 2016 STG COLD FRONT HAS MOVED SOUTH OF I-20 AND SHOULD MOVE WELL OFFSHORE BY THIS AFTN.
A STRONG RIDGE OF HIGH PRESSURE WILL REMAIN POSITIONED OVER THE WEST COAST MONDAY RESULTING IN THE POTENTIAL FOR RECORD WARMTH ACROSS THE BAY AREA AND CENTRAL COAST TOMORROW.
VERY DYNAMIC TROUGH IS CLOSING OFF OVER THE WESTERN GREAT LAKES THIS MORNING. ITS EVOLUTION HAS LARGELY BEEN GUIDED BY A VERY HIGH AMPLITUDE UPSTREAM RIDGE AND A POWERFUL LOW DEEPENING OFF THE EASTERN SEABOARD IMMEDIATELY DOWNSTREAM.
TEMPS WILL CONTINUE THE UPWARD TREND AS A HIGH AMPLITUDE RIDGE BUILDS OVER THE WEST COAST AND H7 TEMPS OVERHEAD WARM TO BETWEEN -4 TO -6. WIDESPREAD MID TO UPPER 30S WITH A FEW LOCATIONS PEAKING IN THE LOW 40S ARE A GOOD BET.
SURFACE RIDGING THAT HAS BUILT IN BEHIND YESTERDAY/S FROPA WILL KEEP TEMPERATURES DOWN AROUND AVERAGE TODAY.
As this upper level system moves into the mid Mississippi valley overnight an upper level ridge axis will begin to build slowly east into the western United States. Subsidence developing in the wake of the upper level trough overnight will yield clear/clearing skies, however based on the expected winds overnight and the temperatures forecast in the mixed layer near the surface will continue to favor lows mainly in the mid 20s. Lighter wind speeds are expected near the Colorado border overnight so lows will be cooler across far western Kansas, especially west/northwest of Garden City.
AS FEATURE CONTINUES TO SHIFT EAST SHOULD LOSE THE HIGHER GUSTS WITH EXCEPTION OF HIGHER ELEVATIONS WEST OF THE VALLEY. WINDS DIMINISH MONDAY NIGHT AS HIGH PRESSURE RIDGE NOSES IN.
DEPENDING ON HOW SOON TEMPS DROP TO THE LOW TO MID 30S WILL BE THE DECIDING FACTOR ON WHEN TRANSITION TO ALL SNOW OCCURS.
A COLD FRONT EXTENDED SOUTHEAST OF A GAINESVILLE TO HAMILTON LINE. TEMPERATURES IMMEDIATELY BEHIND THIS FRONT ARE NOT MUCH COOLER. HIGH TEMPERATURES MONDAY WILL BE MOSTLY IN THE 50S WHICH WILL BE 10 TO 15 DEGREES COOLER THAN THEY WERE TODAY.
HIGH PRESSURE IN THE WEST GULF IS FORCING A LIGHT SOUTH WIND WITH A DRY NORTHWEST FLOW HIGHER UP. A DRY COLD FRONT WILL BE ADVANCING INTO THE CWA OVERNIGHT AND WILL BE MOVING OFFSHORE MONDAY MORNING. WITH A FEW LOW CLOUDS UNDER THE HIGH CIRRUS ALOFT.
/ISSUED 950 PM CST SUN FEB 7 2016/ FEW CHANGES TO SKY GRIDS ONLY THE COLD FRONT IS DRAPED ALONG I-30 NOW AND WILL OVERSPREAD THE FOUR STATE AREA BY DAYBREAK.
1253 AM EST MON FEB 8 2016 A TROUGH OF LOW PRESSURE AT THE SURFACE AND ALOFT WILL PREVAIL THROUGH AT LEAST MID WEEK. A STRONG COLD FRONT WILL CROSS THE AREA LATE MONDAY.
131 AM EST MON FEB 8 2016 A COLD FRONT WILL MOVE THROUGH LATE THIS AFTERNOON AND EVENING.
957 PM MST SUN FEB 7 2016 A BLOCKING WESTERN RIDGE OF HIGH PRESSURE AND WIDESPREAD SNOWPACK ARE THE WEATHER DRIVERS THROUGH THE NEW WEEK.
140 AM MST MON FEB 8 2016 HIGH AMPLIFIED UPPER RIDGE AXIS CENTERED ALONG THE WEST COAST NORTH INTO CANADA IS FORECAST TO SLOWLY MOVE VERY SLOWLY EAST TOWARD LAS VEGAS NORTH THROUGH THE PERIOD.
THE MIDDLE OF THE WEEK WILL FEATURE A PROLONGED PERIOD OF NNW ARCTIC FLOW AS HIGH PRESSURE IN CANADA GRADUALLY NOSES INTO THE NORTHERN PLAINS.
302 AM CST MON FEB 8 2016 AT H5 STRONG WESTERN CONUS RIDGE AND DEEP EASTERN CONUS RIDGE WITH CLOSED LOW OVER THE GREAT LAKES. A BACKDOOR COOL FRONT WILL BRING COOLER TEMPERATURES TO NORTH CENTRAL NEBRASKA TODAY. THIS WILL INHIBIT SOLAR INSOLATION AND WILL KEEP TEMPERATURES OVER NORTH CENTRAL NEBRASKA IN THE LOW 30S WITH MID TO UPPER 30S OVER THE REMAINDER OF WESTERN NEBRASKA. CLOUD COVER AND A LIGHT BREEZE WILL KEEP TEMPERATURES IN THE LOW TO MID 20S OVER NIGHT.
BREEZY TO WINDY CONDITIONS WILL DEVELOP IN THE WAKE OF A COLD FRONT THAT WILL PASS THROUGH THE FORECAST AREA EARLY MONDAY.
DRY AND MUCH WARMER THIS WEEK WITH NEAR RECORD AFTERNOON HIGHS. WATER VAPOR IMAGERY AND 08/00Z UPPER-AIR PLOTS SHOW HIGH PRESSURE OFF THE NORTHERN CALIFORNIA COAST WITH A WEAK UPPER LOW OFFSHORE OF THE CENTRAL BAJA PENINSULA. IR IMAGERY SHOWS PLENTY OF MID AND HIGH LEVEL CLOUDS STREAMING NORTHEAST AHEAD OF THE LOW OFF THE BAJA COAST. TEMPERATURES ACROSS THE REGION RANGED FROM THE LOWER 40S TO THE MID 50S. HIGH PRESSURE WILL BRING DRY CONDITIONS WITH ABOVE AND ABOVE AVERAGE TEMPERATURES THIS WEEK.
1211 AM CST MON FEB 8 2016 LET THE HIGH WIND WARNING EXPIRE AT 06Z.
EARLY AFTERNOON ANALYSIS PLACES A COLD FRONT QUICKLY WORKING SOUTH THROUGH CENTRAL MINNESOTA. TIED TO LOW PRESSURE SLIDING THROUGH THE MINNESOTA ARROWHEAD. BUT THE MAIN QUESTION IS JUST HOW FAR EAST THE HIGHER IMPACTS WILL STRETCH. COMBINE THAT WITH WINDS AND CONDITIONS WILL BE LESS THAN PLEASANT WEST OF THE MISSISSIPPI (AND PERHAPS EVEN ALONG THE RIDGES INTO WISCONSIN).
/ISSUED 228 PM CST SUN FEB 7 2016/ LATEST SURFACE OBSERVATIONS SHOW NORTHERLY WINDS UP TO AROUND 15 TO 20 MPH BEHIND A WEAK COLD FRONT AND SLIGHTLY COOLER TEMPERATURES THAN 24 HOURS PRIOR. ON THE SYNOPTIC SCALE A BROADENING/DEEPENING TROUGH EXTENDED FROM THE UPPER MIDWEST INTO THE CENTRAL PLAINS AND WAS PROGRESSING SOUTHEASTWARD. AS THE TROUGH CONTINUES EASTWARD THROUGH MID WEEK MID LEVEL HEIGHT RISES WILL OCCUR.
THIS SHOULD ALLOW TEMPERATURES TO DROP BELOW THE FREEZING MARK OVER EAST TEXAS AND CENTRAL LOUISIANA.
A COLD FRONT WILL MOVE THROUGH SOUTH-CENTRAL TEXAS BETWEEN 06Z-10Z. THE COLD FRONT IS JUST REACHING OUR NORTHERN BORDER AND WILL CONTINUE TO MOVE THROUGH OUR CWA TONIGHT. THE MAIN SHORT TERM ISSUE WILL BE A COLD FRONT PASSING THROUGH THE CWA OVERNIGHT.
THE FIRST OF TWO STRONG COLD FRONTS WILL BE EXITING EASTERN WISCONSIN RIGHT AROUND SUNRISE. A VERY LARGE CLOSED UPPER LOW WILL CONTINUE TO DROP SOUTH INTO THE GREAT LAKES TODAY.
339 AM CST MON FEB 8 2016 Will start the day with an upper ridge over the western half of the country with a large trough centered over the Great Lakes. The ridge will slowly slide east as the trough moves toward the Atlantic. After another unseasonably warm day yesterday looking for a noticeably cooler day today in post frontal conditions.
236 AM MST MON FEB 8 2016 HIGH AMPLIFIED UPPER RIDGE AXIS CENTERED ALONG THE WEST COAST NORTH INTO CANADA IS FORECAST TO SLOWLY MOVE VERY SLOWLY EAST TOWARD LAS VEGAS NORTH THROUGH THE PERIOD.
1039 PM CST SUN FEB 7 2016 UPPER LEVEL LOW PRESENTLY SEEN ON WATER VAPOR ROTATING THROUGH NORTHERN MINNESOTA. VISIBILITIES HAVE REMAINED JUST EITHER SIDE OF 2 MILES EVEN WHEN SNOW IS OCCURRING AS TEMPERATURES HAVE BEEN ABOVE FREEZING AND MUCH OF THE SNOW HAS SETTLED AND BECOME WET. STILL HINTING AT SOME DEVELOPMENT OF LIGHT SNOW IN OUR EAST THIS EVENING INTO THE OVERNIGHT HOURS AS THE UPPER LEVEL LOW OVER MINNESOTA ROTATES SOUTHWARD. BASED ON TODAYS TRENDS WOULD THINK THAT IT IS ON THE LOW END OF PROBABILITY. TEMPERATURES WILL BE COOLER ON MONDAY BEHIND THE SYSTEM. WITH WEAK IMPULSES OF WARMER AIR TRYING TO MOVE EAST LEADING TO LIGHT SNOW CHANCES.
HIGH PRESSURE WILL REMAIN THE DOMINANT WEATHER FEATURE ACROSS THE REGION THROUGH THE UPCOMING WEEK. AN UPPER RIDGE CONTINUES TO STRENGTHEN OVER THE WEST COAST STATES KEEPING A DRY AND STABLE N-NW FLOW ALOFT OVER UTAH. SEEING AS HOW THERE WAS EXCELLENT SOLAR INSOLATION AND SLIGHTLY WARMER TEMPERATURES TODAY.
1241 AM EST MON FEB 8 2016 STRONG LOW PRESSURE OFF THE NORTH CAROLINA COAST TONIGHT WILL BE WELL OFF THE MID ATLANTIC COAST MONDAY. A COLD FRONT WILL MOVE THROUGH THE FORECAST AREA LATE MONDAY. IT WILL BE DRY IN THE WAKE OF STRONG LOW PRESSURE LIFTING FARTHER NORTHEAST OF THE FORECAST AREA. NEXT UPPER TROUGH WILL DIG INTO THE E CONUS MON/MON NIGHT. MODELS MAINTAIN HIGH AMPLITUDE UPPER PATTERN WITH RIDGE WEST/TROUGH EAST.
A strong deep upper level trough is currently swirling over the Midwest and Great Lakes Region this morning. Temperatures will slowly fall during the day today with temperatures in the lower 30s by this afternoon. Gusty winds up to 35 to 45 mph can be expected especially areas along and west of the Highway 65 corridor. A slick spot of two can not be ruled out on roads or bridges today but significant travel impacts are not expected.
1203 AM CST MON FEB 8 2016 FOR 06Z TAFS /ISSUED 917 PM CST SUN FEB 7 2016/ ONCOMING COLD FRONT IS JUST W OF THE MS RIVER INTO N CNTRL AR. ANY LIGHT RAIN/SHOWERS ASSOCIATED WITH THE COLD FRONT THOUGH DO NOT LOOK TO AFFECT THE AREA UNTIL WELL AFTER MIDNIGHT. ALTHOUGH MID/HIGH-LEVEL CLOUDS WILL THICKEN AND LOWER AS AN UPPER LOW SINKS SEWD OVER THE WESTERN GREAT LAKES AND AN INITIAL DISTURBANCE ROTATING AROUND THIS LOW MOVES ACROSS THE TN VALLEY. STRONG SFC COLD FRONT WILL CROSS THE TWO TERMINALS ARND 15Z.
THIS AFTERNOON COOLER AIR AND GUSTY EAST TO NE WINDS HAVE MOVED INTO THE SERN PLAINS. THE HIGHER ELEVATIONS. THE GRADIENT OVR THE AREA WL WEAKEN ON MONDAY AS A TROF OVR THE PLAINS STATES SLOWLY SHIFTS EASTWARD. AND AN UPR RIDGE BUILDS OVR THE WRN STATES. ONCE THE TROUGH TO THE E SHIFTS EWD BY TUE OR EARLY WED. EXPECT TEMPS IN THE 60S OVER THE PLAINS AND 40S FOR THE HIGH VALLEYS.
STRONG HIGH PRESSURE ALOFT OVER CALIFORNIA WILL COMBINE WITH OFFSHORE FLOW TO BRING AREAS OF STRONG GUSTY NORTHEAXTERLY WINDS.
346 AM CST MON FEB 8 2016 SUBTLE CAA WILL CONTINUE TODAY BEHIND A COLD FRONT THAT'S MOVED INTO SOUTH CENTRAL TX EARLY THIS AM. NORTH WINDS ARE EXPECTED THROUGH TUE BEFORE BECOMING SOUTHERLY AGAIN WED AFTERNOON AS A LEE TROUGH DEVELOPS. THE GFS IS MORE AGGRESSIVE WITH CAA THROUGH FRI AM SINCE ITS DEEPER WITH THE AFOREMENTIONED TROUGH, BUT IT APPEARS TO BE THE OUTLIER RIGHT NOW SO LEANED CLOSER TO WARMER ECMWF SOLUTION FOR NOW ESPECIALLY FOR THE SOUTHERN ZONES. THERE IS BETTER AGREEMENT (GFS/GEFS/ECMWF) ON MORE SIGNFICANT CAA IMPACTING THE REGION SAT AM AS THE MID TO UPPER TROUGH DEEPENS OVER THE EASTERN CONUS.
Regardless, models continue to show decent surface based CAPE, for winter, with saturation occurring through the lower half of a deep dendritic zone. The highest impact snows will be localized given showery nature to the precipitation and it's likely that not everyone will see snow. The ridging over the west will keep our area in northwesterly flow, limiting any precipitation chances. Wind speed shear will also be a factor overnight in the lower levels, though increased surface winds should mitigate this to a degree.
457 AM EST MON FEB 8 2016 LIGHT RAIN IS MOVING IN FROM THE WEST OUT AHEAD OF A PRE- FRONTAL TROUGH. UNTIL A VIGOROUS SHORT WAVE TROUGH ROTATES THROUGH THIS AFTERNOON. THE ONLY EXCEPTION TO THIS WILL BE THE HIGHER ELEVATIONS ALONG THE SOUTHEAST AS THE COLUMN COOLS QUICKER ALOFT.
256 AM MST MON FEB 8 2016 A 125 KT JET ANCHORED BETWEEN AN UPPER RIDGE OVER THE WESTERN STATES AND AN UPPER LOW OVER THE GREAT LAKES WILL PUSH EAST INTO THE GREAT PLAINS TODAY. WARM ADVECTION WITH SLIGHT DOWNSLOPING IS EXPECTED TODAY TO BRING WARMER TEMPERATURES TODAY ACROSS THE AREA WITH THE WARMEST AREAS FOUND OVER THE FOOTHILLS AND METRO AREAS. IT COULD STAY COOLER. GUSTS TO 60 MPH WILL BE POSSIBLE IN THE HIGHER TERRAIN AND INTO SOUTH PARK. THOUGH IT WILL BE A WARMER NIGHT UNDER THE WARM ADVECTION AND BREEZY NORTHWEST WIND PATTERN. A HIGH AMPLITUDE RIDGE CENTERED OVER THE WESTERN U. WILL BRING DRY AND WARMER WEATHER TO THE FORECAST AREA FOR THE REST OF THE WEEK.
404 AM EST MON FEB 8 2016 A COLD FRONT WILL CROSS THE AREA TODAY COMBINED WITH A DEEPENING TROUGH ALOFT. OCCASIONAL SNOW WILL CONTINUE INTO MIDWEEK AS THE TROUGH ALOFT MOVES SLOWLY EAST ACROSS THE AREA.
THIS COLD FRONT WILL MOVE THROUGH THE REGION OVERNIGHT WITH A MARKED DECREASE IN TEMPERATURES EXPECTED BY MONDAY MORNING. WHILE THE AIR WILL BE COOLER. WITH MUCH OF THE COLUMN WELL BELOW FREEZING. EVEN THOUGH SURFACE TEMPERATURES MAY ONLY BE IN THE LOW TO MID 30S.
1212 PM EST WED FEB 3 2016 A NEW LOW PRESSURE AREA WAS FORMING OVER LOWER MICHIGAN THIS MORNING. SOME RAIN AND SNOW SHOWERS WILL BECOME ALL SNOW AS TEMPERATURES DROP TOWARD FREEZING. LOWS TONIGHT WILL FALL INTO THE LOWER TO MIDDLE 20S. SOME COLDER AIR WAS BEGINNING TO SPREAD INTO THE AREA FROM THE NORTHWEST ON THE SOUTHWEST SIDE OF THIS LOW. UPSTREAM RIDGE WITH LOW LEVEL/8H COLD POOL AT GREATEST EXTENT THU AM.
COLD FRONT IS NOW PUSHING THROUGH THE WEST AND HAVE BUMPED UP WINDS ACROSS THE WEST THIS AFTERNOON. LITTLE MORE ROBUST RETURNS ACROSS THE NORTH CENTRAL WITH A FEW HUNDREDTHS ACCUMULATION ALONG AND NORTH OF THE HIGHWAY 2 CORRIDOR. AS THE TROUGH PUSHES OFF TO THE EAST THIS SNOW ACTIVITY IS EXPECTED TO PUSH EASTWARD THROUGH THE MORNING AND DIMINISH.
/ISSUED 1035 AM CST WED FEB 3 2016/ DRY AIR CONTINUES TO FLOW IN TO THE REGION BEHIND COLD FRONT THAT NOW EXTENDS OVER CENTRAL GULF. DAYTIME TEMPS ARE RUNNING ABOUT 6 DEGREES COOLER THEN FORECAST UNDER THE CLOUD SHIELD.
FOLLOWED BY STRONG HIGH PRESSURE FOR THE END OF THE WEEK. THE BACK EDGE OF THE LONGWAVE TROUGH WILL CONTINUE TO DEPART THE REGION THROUGH EARLY AFTERNOON.
645 PM EST WED FEB 3 2016 COLDER AIR WILL OVERSPREAD THE REGION TONIGHT AS AN AREA OF LOW PRESSURE TRACKS NORTHEAST ACROSS QUEBEC.
324 PM CST WED FEB 3 2016 A CLIPPER SYSTEM WITH THE CENTER OF THE LOW OVER SOUTHERN MANITOBA WILL TRACK THROUGH THE FORECAST AREA THROUGH TONIGHT. WEAK RADAR RETURNS OVER CENTRAL NORTH DAKOTA ASSOCIATED WITH THE WARM FRONT WILL MOVE THROUGH THE EASTERN CWA THIS AFTERNOON WITH LITTLE OR NO ACCUMULATION EXPECTED. COLD ADVECTION BEHIND THE COLD FRONT TONIGHT BUT WINDS AND MOSTLY CLOUDY SKIES SHOULD KEEP TEMPERATURES FROM FALLING INTO THE SINGLE DIGITS. HIGH PRESSURE MOVES ACROSS THE FORECAST AREA ON THURSDAY WITH LIGHT WINDS. COOLER IN THE EAST THURSDAY WITH HIGHS IN THE MID TEENS TO MID 20S. WARM ADVECTION RETURNS THURSDAY AFTERNOON WEST WITH HIGHS REACHING THE LOW TO MID 30S.
Primary Short and Medium Range deterministic guidance and GFS Ensemble are in fairly good agreement on slowly moving the leading edge of the trough shear axis through the WFO PAH forecast area this morning, with the main trough axis working through approximately 24 hours later.
A STRONG COLD FRONT THAT BROUGHT NUMEROUS SHOWERS/THUNDERSTORMS. ASSOCIATED WITH THE EAST SIDE OF A TROUGH AXIS THAT WAS MOVING ACROSS THE EASTERN CONUS. LOWS WILL FALL INTO THE LOWER 30S. OTHERWISE COOLER CONDITIONS AS MORE SUN RETURN ON THU. A RETURN OF DEEP LOW PRESSURE OVER EASTERN CANADA WILL PRODUCE A RIDGING WEST/TROUGHING EAST SETUP.
1151 AM CST WED FEB 3 2016 The upper level trough that was the catalyst for yesterday's showers and thunderstorms, is swinging through the region this morning. These light rain and snow chances will continue through mid-morning before the upper level trough moves northeast into the Great Lakes region. The high pressure ridge will quickly shift east on Thursday and winds will return out of the southwest.
A COOL AND DRY AIRMASS WILL REMAIN SITUATED ACROSS THE REGION THROUGH THE SHORT TERM AS HIGH PRESSURE SETTLES. AND IN THE LOW 40S ALONG THE COAST AND RIO GRANDE. A SECOND SURGE OF HIGH PRESSURE WILL DEVELOP AGAIN TONIGHT THROUGH THURSDAY MORNING.
A MUCH MORE QUIET DAY IS UNDERWAY ACROSS THE TENNESSEE VALLEY IN THE WAKE OF THE RECENTLY DEPARTED COLD FRONT TO OUR EAST. HIGH TEMPS TODAY MAY REACH 60 DEGREES, BUT THE COOLER AND DRIER AIR WILL ADVECT (EVENTUALLY) INTO THE REGION THIS EVENING/TONIGHT FOR TOMORROW.
ABUNDANT SUNSHINE HAS ALLOWED TEMPS TO WARM INTO THE LOWER 60S COAST AND MID 50S NORTH EARLY THIS AFTERNOON.
522 PM EST WED FEB 3 2016 A STRONG COLD FRONT WILL CROSS THE AREA THIS EVENING THEN STALL NEAR THE COAST THURSDAY.
/ISSUED 1011 AM CST WED FEB 3 2016/ COOLER AND DRIER AIR IS FILTERING INTO THE REGION ON WESTERLY WINDS AS HIGH PRESSURE BUILDS IN BEHIND THE DEPARTING SYSTEM. LINGERING SHOWERS BEHIND A DEPARTING COLD FRONT WILL MOVE EAST OF THE CWA BY SUNRISE. A SECONDARY COLD FRONT IS PUSHING INTO THE MIDSOUTH AT THIS TIME. COOLER AND DRIER AIR WILL FILTER INTO THE MIDSOUTH BEHIND THE SECONDARY COLD FRONT. THE FIRST IN A SERIES OF UPPER TROFS WILL MOVE INTO THE MIDSOUTH TONIGHT INTO THURSDAY. LITTLE IF ANY CLOUD COVER IS EXPECTED WITH THIS FIRST TROF. HIGH PRESSURE WILL BEGIN TO BUILD INTO THE AREA. LOWS WILL RANGE FROM THE MID 20S TO THE LOWER 30S.
