Aikyam-Lab/Synoptic-Bench huggingface dataset:
TEMPERATURES FOR THE MOST PART ARE WELL ABOVE FREEZING ALTHOUGH A FEW ICE PELLETS CAN'T BE RULED OUT ALONG THE TN/KY BORDER AND THE NORTHERN PLATEAU.
1224 PM CST MON FEB 15 2016 WITH THE COLD FRONT CONTINUING TO MAKE ITS WAY ACROSS SE TX THIS AFTN WE SHOULD BE SEEING THE END OF THE PCPN/CLOUDS FROM THE NW. SFC ANALYSIS AT 16Z HAS COLD FRONT ON THE DOOR STEP OF CROCKETT TO CALDWELL.
AS HIGH PRESSURE DRIFTS SOUTHEAST INTO THE GULF WATERS SOUTHEAST WIND RETURNS TO THE VALLEY VERY QUICKLY TUE AFTERNOON RETURNING LOW LEVEL MOISTURE LAYER PULLING N ALONG THE INTERNATIONAL BORDER. THE GRADIENT GRADUALLY STRENGTHENS AS HIGH PRESSURE TAKES CONTROL OF THE SOUTHEAST AND MOST OF THE GULF WATERS KEEPING SOUTHEASTERLY WINDS THROUGH THE NIGHT.
305 PM CST MON FEB 15 2016 WINDS HAVE TURNED TO THE WEST-SOUTHWEST AND PICKED UP A BIT ON THE CAPROCK IN RESPONSE TO A TROUGH DIVING SOUTHEASTWARD OUT OF CANADA INTO THE NORTHERN PLAINS. A COLD FRONT WILL MOVE THROUGH THE AREA TUESDAY.
INCREASE IN MOST 12Z MODEL QPF IS STARTING TO BRING CONCERN TO ADVISORY LEVEL FREEZING RAIN AND/OR SNOW AMOUNTS. WITH MODERATING LOW LEVEL TEMPERATURES HIGHS ILL BE WARMER THAN THEY HAVE BEEN FOR AWHILE. CLIMBING TO 40 TO 45 WEST OF THE JAMES TO THE LOWER 30S OVER PARTS OF SOUTHWEST MINNESOTA AND NORTHWEST IOWA. A LITTLE WORRIED THAT HIGHS COULD COME IN A COUPLE OF DEGREES COOLER IN SOUTHWEST MINNESOTA AND NORTHWEST IOWA AS THE LAST FEW DAYS HAVE FOLLOWED THAT TREND. SUSPECT A LITTLE LIGHT FREEZING RAIN WILL BE POSSIBLE ON THE LEADING EDGE OF THE LIFT IN THE LIGHTER PRECIPITATION BUT SHOULD CHANGE TO SNOW WHEN THE DEEPER MOISTURE AND STRONGER LIFT MOVE IN.
ALTHOUGH HIGH PRESSURE BUILDING WELL INTO TEXAS. COLD FRONT IN ASSOCIATION WITH THE CONVECTION WILL CONTINUE TO PUSH SOUTH AND EAST THROUGH THE AFTERNOON AND EXPECT ALL CONVECTION TO BE NEAR OR EAST OF OUR EASTERN MOST MLU TERMINAL LOCATION BY 21Z IF NOT EARLIER. OVERNIGHT WITH FRESHLY WET SOILS AND WEAK 1014MB HIGH PRESSURE NOW IN OKLAHOMA.
COLD FRONT IN ASSOCIATION WITH THE CONVECTION WILL CONTINUE TO PUSH SOUTH AND EAST THROUGH THE AFTERNOON AND EXPECT ALL CONVECTION TO BE NEAR OR EAST OF OUR EASTERN MOST MLU TERMINAL LOCATION BY 21Z IF NOT EARLIER. OVERNIGHT WITH FRESHLY WET SOILS AND WEAK 1014MB HIGH PRESSURE NOW IN OKLAHOMA.
DUE MAINLY TO COOLER EASTERLY FLOW IN GEORGIA. A 1008 LOW PRESSURE SYSTEM IS OVER NORTH CENTRAL LOUISIANA. MESOSCALE MODELS MOVE THE AREA OF LOW PRESSURE NORTHEAST THROUGH THE DAY INTO GEORGIA. DESPITE CLOUD COVER THIS SHOULD ALLOW TEMPERATURES TO CLIMB INTO THE LOWER TO MID 50S SOUTH OF THE TENNESSEE RIVER. A COLD FRONT WILL ARRIVE AT KMSL BY 01Z AND KHSV BY 03Z WITH WINDS SHIFTING TO THE NW.
HOWEVER KYKM, KRDM AND KBDN WILL SEE SOME THIN HIGH CLOUDS STREAMING THROUGH THE MID/UPPER LEVEL RIDGE OF HIGH PRESSURE OVER THE PACIFIC NORTHWEST OVER THE NEXT 24 HOURS FOR CLOUD BASES AT KYKM SCT-BKN 25000 FT AGL.
THE HIGH WIND HIGHLIGHT WILL CONTINUE. BUT HIGH WIND IMPACTS SHOULD BE ON THE LOW SIDE OVER THE NEXT FEW DAYS.
306 PM CST MON FEB 15 2016 Unseasonably warm day well under way across eastern Oklahoma and western Arkansas even as a surface trof moves out of eastern Oklahoma and into western Arkansas.
CLEAR AND COOLER TONIGHT IN THE WAKE OF THIS MORNINGS COLD FRONT.
AN AREA OF LOW PRESSURE WILL PERSIST OVER THE GREAT BASIN THROUGH THE WEEKEND. THE UPPER LOW OVER THE GREAT BASIN WILL HAVE AT LEAST TWO MORE S/WVS MOVE THROUGH NORTHERN ARIZONA THIS WEEKEND.
308 AM EST SAT NOV 28 2015 A SLOW MOVING COLD FRONT WILL SAG SOUTHWARD ACROSS CENTRAL PA TODAY.
WITH FAIRLY LIGHT SOUTHERLY WINDS AND INCREASING SCT/BKN DECKS OF LOW TO MID CLOUDS AS A COLD FRONT SLOWLY APPROACHES FROM THE WEST LATE IN THE PERIOD.
256 AM EST SAT NOV 28 2015 A COLD FRONT CURRENTLY SITUATED ACROSS WESTERN TENNESSEE INTO THE LOWER OHIO VALLEY WILL CONTINUE TO SLOWLY TRACK TOWARD THE EASTERN TENNESSEE VALLEY OVER THE NEXT 24 HOURS.
1157 PM EST FRI NOV 27 2015 AVIATION ANY LEFT OVER SHOWERS WILL COME TO AN END BY LATE EVENING AS A LARGE HIGH PRESSURE SYSTEM CONTINUES TO FEED COOLER AND DRIER AIR IN THE REGION. THIS LARGE HIGH PRESSURE SYSTEM WILL BRING CONSIDERABLE SUNSHINE WITH SEASONABLY COOL TEMPERATURES THROUGH THE WEEKEND. WHAT WE AREA WATCHING FOR TONIGHT IS OUTSIDE CHANCE OF A LITTLE FREEZING DRIZZLE/ LIGHT RAIN SOUTH OF INTERSTATE 94.
THE COLD FRONT HAS JUST EASED INTO SHREVEPORT AND HAS PUSHED OVER INTO THE NORTHERN THIRD OF BOSSIER PARISH. WORKING IN THE BACK DOOR WILL TAKE MORE TIME THAN USUAL WITH THE COLD FRONT ONLY EASING INTO ARKADELPHIA NOW. THE WATER VAPOR SHOWS THE UPPER LOW SPINNING ITS WHEELS OVER NEVADA FOR THE MOST PART.
247 AM CST SAT NOV 28 2015 LATEST WATER VAPOR IMAGERY SHOWS A DEEP CLOSED LOW IN THE WEST WITH A PLUME OF MID-HIGH LEVEL MOISTURE STREAMING NORTHEAST ACROSS OUR REGION. SNOW AND FREEZING RAIN. LIGHT SLEET/SNOW/FREEZING RAIN WILL CONTINUE INTO THE EARLY/MID MORNING HOURS ACROSS THE SOUTHEAST THIRD WITH A GRADUAL DECREASE IN PROBABILITIES THROUGHOUT THE DAY. MODELS LINGER LOW LEVEL MOISTURE THROUGH MUCH OF THE DAY WHICH WILL RESULT IN OVERCAST CONDITIONS AND POSSIBLY SOME FREEZING DRIZZLE.
00Z MODELS ARE IN GOOD AGREEMENT THAT MOST /IF NOT ALL OF THE CWA/ WILL BE ABOVE FREEZING BY MIDDAY. CONCERN STILL REMAINS ABOUT SATURDAY NIGHT AS FREEZING TEMPS RESUME UNDER A LINGERING AXIS OF MOIST ASCENT. PERIODS OF FREEZING RAIN AND FREEZING DRIZZLE OVERNIGHT WILL CONTINUE THROUGH MOST OF SATURDAY MORNING BEFORE CEASING AT LBB AND PVW FIRST. BEFORE CHANGING TO RAIN AT CDS AS TEMPS WARM ABOVE FREEZING.
315 AM CST SAT NOV 28 2015 CLOSED UPPER LOW REMAINS OVER THE INTERMOUNTAIN WEST EARLY THIS MORNING. STRONG SOUTHWEST FLOW IS EXPECTED TO REMAIN ACROSS THE REGION UNTIL THE UPPER LOW FINALLY LIFTS OUT.
A VERY SLOW MOVG COLD FRONT CREATING STG INVERSION TO KEEP IFR CIGS IN PLACE. THE COLD FRONT HAS JUST EASED INTO SHREVEPORT AND HAS PUSHED OVER INTO THE NORTHERN THIRD OF BOSSIER PARISH. WORKING IN THE BACK DOOR WILL TAKE MORE TIME THAN USUAL WITH THE COLD FRONT ONLY EASING INTO ARKADELPHIA NOW. THE WATER VAPOR SHOWS THE UPPER LOW SPINNING ITS WHEELS OVER NEVADA FOR THE MOST PART.
TONIGHT THROUGH SATURDAY THE AREA OF LOW PRESSURE OVER THE DESERT SOUTHWEST WILL BEGIN TO SHIFT ITS ELONGATION FROM CALIFORNIA TO UTAH/COLORADO. ANY SNOWFALL ACCUMULATION IS NOT EXPECTED TO BE SIGNIFICANT ACROSS THE LOWER ELEVATIONS. THE LOW IS CUT OFF AND IS PART OF A REX BLOCK. THE LOW HAS LIMITED MOISTURE BUT STILL MAINTAINS A COLD POOL ALOFT FROM THE MID LEVELS 700 MB UP THROUGH THE 500 MB LEVEL UP TO THE TROPOPAUSE. EXPECT THE LOW TO PRODUCE MORE STRATUS AND LIGHT SNOW WITH LOW PRECIPITATION RATES.
255 AM CST SAT NOV 28 2015 Strong upper low over the Great Basin will wobble northeast the next few days. This low has brought cold rain to the region.
THIS MAKES SENSE WITH LOW-LEVEL CONVERGENCE ALONG A WARM FRONT LIFTING N ACROSS THE CWA. WILL NEED TO WATCH FOR FREEZING DRIZZLE POTENTIAL ACROSS THE HIGH PLAINS. COOLER TEMPS SHOULD BE FOUND FARTHER TO THE NORTH AND WEST AS FEWER CLOUDS SHOULD YIELD BETTER RADIATIONAL COOLING.
1107 PM CST FRI NOV 27 2015 A cold front has made it almost all the way through the region except for the southeast corner of the cwfa. Temperatures well back behind the front have stabilized with the sfc freezing line just west and nw of the cwfa.
COULD BE SOME AT LEAST PATCHY FOG AS WELL AHEAD OF THE FRONT WHERE DEWPOINTS ARE IN THE LOWER 70S. /ISSUED 308 PM CST FRI NOV 27 2015/ COLD FRONT IS MOVING INTO OUR NORTHERN COUNTIES THIS AFTERNOON. CURRENT READINGS WELL BEHIND THE BOUNDARY (NORTHERN HILL COUNTRY AREA) ARE IN THE LOWER TO MID 40S WHILE UPPER 70S TO AROUND 80 CAN BE FOUND ACROSS MUCH OF SOUTHEAST TEXAS. WILL CARRY THE HIGHER RAIN CHANCES UP NORTH AND THE LOWER NUMBERS IN/AROUND THE GALVESTON BAY AREA WHICH HAS THE POTENTIAL TO REMAIN AHEAD OF THE FRONT FOR MOST OF THE WEEKEND. SO FORECAST CONFIDENCE ON BOTH TEMPERATURES AND RAIN CHANCES IS ON THE LOW SIDE.
352 AM EST SAT NOV 28 2015 PERIODS OF RAIN CAN BE EXPECTED TODAY INTO TONIGHT AS A COLD FRONT SAGS SLOWLY SOUTHEAST THROUGH THE OHIO VALLEY.
331 AM CST SAT NOV 28 2015 A few rounds of light freezing rain/drizzle will continue to be a concern today and tonight as moisture continues to pool in the vicinity of a nearly stalled frontal boundary sitting south of the forecast area. Temperatures are hovering a few degrees below the freezing mark across eastern KS and portions of northwest MO, and are generally not expected to budge today, making any precipitation that falls potentially hazardous in those areas. As a result, will elect to extend the freezing rain advisory through this evening for the same areas currently included. Additional occasional periods of light precipitation are possible again tonight, but if surface temps can rise even a degree or two, any further extension of the freezing rain advisory may not be warranted, so will re-evaluate when temp trends become clearer.
324 AM EST SAT NOV 28 2015 A COLD FRONT HAS BROUGHT COOLER TEMPERATURES TO THE REGION.
940 PM PST FRI NOV 27 2015 Chilly temperatures and clear skies are expected through at least Friday as strong high pressure builds over the Pacific Northwest.
1140 PM CST FRI NOV 27 2015 QUIET WEATHER INTO THE WEEKEND AS A STRONG AREA OF HIGH PRESSURE BUILDS OVER THE NORTHERN PLAINS TO MID/UPPER MISSISSIPPI VALLEY. ON THE SYNOPTIC SCALE THE MAIN FEATURE OF NOTE IS THE STRONG AREA OF HIGH PRESSURE SITUATED OVER SOUTH DAKOTA THIS AFTERNOON. THIS HIGH GRADUALLY MIGRATES EASTWARD INTO THE MID/UPPER MISSISSIPPI VALLEY IT WILL GRADUALLY WEAKEN. LOWS TONIGHT IN THE LOW TEENS TO SINGLE DIGITS. COLDEST FROM THE TWIN PORTS EAST ACROSS NORTHWEST WISCONSIN WHERE THE LOW-LEVEL RIDGE AXIS IS EXPECTED TO BE OVERNIGHT. HIGHS IN THE LOW 30S ON SATURDAY.
COLD FRONT OVER THE NW MTNS AT 06Z WILL VERY SLOWLY PROGRESS SE INTO CENTRAL PA EARLY THIS AM. SATL-DERIVED PWAT LOOP SHOWING ATMOSPHERIC RIVER OF ANOMALOUS PWATS EXTENDING FROM THE EASTERN PACIFIC ALL THE WAY THRU PA AHEAD OF APPROACHING COLD FRONT. SINCE THE SFC REFLECTION OF THE LOW PRESSURE IS SO WEAK AND THE DRIVING FORCE IS A FAST-MOVING THING. IT MAY EITHER BUBBLE UP SOME LIGHT RAIN INTO THE NORTH - OR THE LOW LEVEL MOISTURE COULD MAKE FOR SOME DZ. COLD FRONT SAGS TO THE SOUTH OF PA WITH DIMINISHING CHANCES FOR SHOWERS ACROSS THE SOUTH.
327 AM EST SAT NOV 28 2015 THE AVIATION SECTION HAS BEEN UPDATED BELOW INDIANA WILL LIE BETWEEN A FRONT TO OUR SOUTH AND A HIGH PRESSURE SYSTEM TO OUR NORTH TODAY. THE HIGH PRESSURE SHOULD EXPAND SOUTH AND TAKE CONTROL OF HOOSIER WEATHER.
The freezing line is currently at Midland/Odessa and moving south. Look for temperatures to slowly rise above freezing Saturday afternoon with precip becoming all rain at the terminals except for possibly KHOB.
COULD BE SOME AT LEAST PATCHY FOG AS WELL AHEAD OF THE FRONT WHERE DEWPOINTS ARE IN THE LOWER 70S.
/ISSUED 934 PM CST FRI NOV 27 2015/ SCATTERED SHOWERS OVER THE GULF ARE STREAMING INTO SOUTHWEST LOUISIANA AND SOUTHEAST TEXAS THIS EVENING AHEAD OF A COLD FRONT. A COLD FRONT WILL APPROACH SE TX SAT. WITH HIGH PRESSURE WEAKENING OVER THE SOUTHEAST CONUS. AND THE APPROACH OF LOW PRESSURE AND ACCOMPANYING COLD FRONT OVER EAST TEXAS.
1001 PM MST FRI NOV 27 2015 THERE IS A NARROW CORRIDOR OF FREEZING DRIZZLE OVER THE TRI-STATE AREA CURRENTLY. THE ICE ACCUMULATION WILL NOT HAVE AS MUCH OF AN IMPACT AS THE FREEZING DRIZZLE LAST NIGHT. EARLY AFTERNOON WV IMAGERY AND RAP UPPER LEVEL ANALYSIS SNOW LARGE CLOSED LOW STILL IN PLACE ACROSS THE GREAT BASIN WITH EXTENSIVE PLUME OF PACIFIC MOISTURE ACROSS THE SOUTHERN PLAINS. A DRY LAYER IN THE LOWEST 6000 KFT OF THE ATMOSPHERE DEVELOPED OVER NEBRASKA THIS MORNING AND ADVECTED SOUTH ACROSS OUR CWA PUTTING AN END TO PRECIP. THERE IS AN INDICATION OF RETURN FLOW/UPSLOPE FLOW DEVELOPING LATE TONIGHT WITH INCREASING MOISTURE IN THE -3 TO -8C LAYER SUPPORTIVE OF VERY LIGHT FREEZING RAIN OR FREEZING DRIZZLE.
441 AM EST SAT NOV 28 2015 A SLOW MOVING COLD FRONT WILL SAG SOUTHWARD ACROSS CENTRAL PA TODAY.
OVERNIGHT LOWS ARE EXPECTED TO RANGE FROM THE LOWER TO MID 50S OVER INTERIOR AREAS AND IN THE UPPER 50S TO LOWER 60S NEAR THE COAST.
131 AM EST SAT NOV 28 2015 A COLD FRONT WILL FINISH ITS TREK THROUGH THE REGION THROUGH THE MORNING.
COLD FRONT STRETCHING FROM SE LOWER MI TO NW AR WILL CONTINUE TO SAG VERY SLOWLY SOUTHEAST. THERE WAS ANOTHER LARGE TEMPERATURE DIFFERENCE BETWEEN THE RIDGES AND VALLEYS LAST NIGHT. TONIGHT THE COLDER VALLEY LOCATIONS WILL ONLY BE A FEW DEGREES COOLER THAN RIDGE LOCATIONS. CLOUDS AND RAIN WILL KEEP TEMPERATURES A LITTLE COOLER ON SATURDAY THAN TODAY. A LARGE UPPER LOW OVER THE WESTERN CONUS AT THE START OF THE PERIOD WILL SLOWLY MOVE EAST TOWARD THE GREAT LAKES. WHICH WILL PULL THE FRONTAL BOUNDARY NORTH AS A WARM FRONT.
COLD FRONT ENTERING NW COUNTIES AT 04Z WILL VERYU SLOWLY PROGRESS TO THE SE THROUGH SAT. SINCE THE SFC REFLECTION OF THE LOW PRESSURE IS SO WEAK AND THE DRIVING FORCE IS A FAST-MOVING THING. IT MAY EITHER BUBBLE UP SOME LIGHT RAIN INTO THE NORTH - OR THE LOW LEVEL MOISTURE COULD MAKE FOR SOME DZ. COLD FRONT SAGS TO THE SOUTH OF PA WITH DIMINISHING CHANCES FOR SHOWERS ACROSS THE SOUTH.
340 AM EST SAT NOV 28 2015 A SFC COLD FRONT STRETCHES FROM NEW ENGLAND SOUTHWESTWARD INTO THE MIDWEST.
NEAR TERM AND SHORT TERM SECTIONS HAVE BEEN UPDATED BELOW INDIANA WILL LIE BETWEEN A FRONT TO OUR SOUTH AND A HIGH PRESSURE SYSTEM TO OUR NORTH TODAY. THE HIGH PRESSURE SHOULD EXPAND SOUTH AND TAKE CONTROL OF HOOSIER WEATHER.
355 AM CST SAT NOV 28 2015 EARLY MORNING SFC ANALYSIS SHOWS THE COLD FRONT ON THE DOOR STEP OF THE FORECAST AREA WITH OBS SHOWING TEMPS IN THE UPPER 60S/AROUND 70 ACROSS THE WRN ZONES. WATER VAPOR IMAGERY SHOWS THE MID/UPPER-LEVEL RIDGE AXIS NOW FARTHER EAST OF THE REGION WHILE A CUTOFF LOW IS NOTED OVER THE WRN CONUS. THE MAIN STORY OF THIS FORECAST PERIOD CONTINUES TO BE THE APPROACHING COLD FRONT AND ITS VERY SLOW ERLY PUSH AS IT REMAINS SOMEWHAT PARALLEL TO THE FLOW ALOFT. ALLOWING RAINS AND COOLER AIR TO SETTLE IN IN ITS WAKE OVER THESE AREAS.
1158 PM CST FRI NOV 27 2015 VERY LITTLE CONCERNS THRU TOMORROW AS HIGH PRESSURE MOVES OVERHEAD. NEW SNOW COVER MAY ALLOW FOR COOLER TEMPS THEN FORECAST. ESPECIALLY IN THE LOW LYING AREAS WHERE A COUPLE INCHES FELL SOUTH OF THE TWIN CITIES. WINDS WILL SHIFT TO THE SW TOMORROW AS THE HIGH MOVES OFF TO THE SE.
/ISSUED 156 PM EST FRI NOV 27 2015/ DECENT AGREEMENT IN GUIDANCE FOR SHORT TERM TRENDS AS RIDGING ACROSS SOUTHEAST CONUS IS PROGGED TO WEAKEN AND ALLOW FOR MORE ZONAL FLOW WITH AN APPROACHING ELONGATED FRONTAL SYSTEM FROM THE NORTHWEST BY LATE SATURDAY. THIS MAY LIMIT TEMPS IN THE NORTH TO BE SLIGHTLY COOLER THOUGH STILL WARM.
THE PREDOMINANT FORM OF PRECIPITATION WILL BE FREEZING RAIN AND SLEET IN SOUTHEASTERN COUNTIES WHILE SNOW AND SLEET WILL OCCUR ACROSS NORTHWESTERN PANHANDLE COUNTIES. A STATIONARY BAROCLINIC ACCESS NEAR OUR SOUTHEASTERN COUNTIES COMBINED WITH FAVORABLE DYNAMICS WILL PRESENT MODERATE FREEZING RAIN THROUGH THE OVERNIGHT HOURS. PASSING PRECIPITATION IN THE FORM OF FREEZING RAIN AND SLEET WILL CONTINUE OVER KAMA THRU 28/11Z WITH OTHER TAF SITES EXPERIENCING FREEZING DRIZZLE.
ANOTHER UNSEASONABLY WARM DAY EXPECTED FOR THE FORECAST AREA AS UPPER LEVEL RIDGE EXTENDS NE ACROSS THE REGION. A COLD FRONT IS CURRENTLY LOCATED ALONG THE TEXAS COAST TO SHREVEPORT AND CONTINUES NORTHEAST. LITTLE MOVEMENT IS EXPECTED FROM THIS BOUNDARY TODAY AS UPPER LEVEL LOW BEHIND IT CENTERED NEAR THE DESERT SOUTHWEST IS VIRTUALLY CUTOFF AND NOT MOVING ENOUGH TO PROGRESS THE FRONT SOUTH.
358 AM CST SAT NOV 28 2015 RAIN HAS EXPANDED NORTHEASTWARD FROM TEXAS INTO WESTERN TENNESSEE ALONG A SLOW MOVING COLD FRONT.
AN UPPER LEVEL RIDGE WILL CONTINUE OVER SOUTHERN BRITISH COLUMBIA AND NORTHERN WASHINGTON THROUGH AT LEAST SATURDAY. MEANWHILE AN UPPER LOW WILL REMAIN OVER THE GREAT BASIN. HAVE FOR NOW ISSUED AN AIR STAGNATION ADVISORY FOR THE YAKIMA AND KITTITAS VALLEYS, AND THE LOWER BASIN IN WASHINGTON.
HIGH PRESSURE HAS BEGUN TO PUSH INTO NORTHWESTERLY IOWA AND WILL CONTINUE TO SLOWLY PUSH SOUTH OVERNIGHT. WILL LIKELY SEE FREEZING RAIN.
STILL BELIEVE THAT MOST OF THE PRECIPITATION WILL FALL IN THE FORM OF FREEZING RAIN WITH ONE-QUARTER TO ONE-THIRD OF AN INCH POSSIBLY ACCUMULATING OVERNIGHT. MAJORITY OF THE ROAD ISSUES WILL BE CONFINED TO BRIDGES AND OVERPASSES.
With temperatures this morning continuing around the freezing mark, across some of our northern counties, a wintry mix of precipitation remains possible. Beyond noon and for tonight, temperatures should remain above the freezing mark across all of West Central Texas.
SOME LIGHT FREEZING DRIZZLE POSSIBLE FROM KIMBALL TO SIDNEY PER PROGGED SOUNDINGS.
00Z TAF CYCLE WDSPRD MVFR AND IFR CONDITIONS IN LOW CLOUDS AND PERIODS OF FROZEN OR FREEZING PCPN WILL CONTINUE TONIGHT INTO SATURDAY. FREEZING PCPN WILL FAVOR LOCATIONS ALONG AND SE OF A LINE FM KTCC TO KSRR.
AREA WILL BE BETWEEN WEAKENING HIGH PRESSURE OVER THE CAROLINAS AND AN INVERTED TROUGH JUST EAST OF THE BAHAMAS. TEMPERATURES WILL REMAIN MILD WITH HIGHS IN THE LOWER 80S INTERIOR AND UPPER 70S COAST. THE HIGH SURF ADVISORY CONTINUES TO BE WARRANTED WITH SIMILAR AMOUNTS OF BEACH EROSION OCCURRING DURING THE HIGH TIDE THIS MORNING.
UPPER RIDGE AXIS ACROSS THE AREA WILL AGAIN RESULT IN WARM TEMPERATURES TODAY REACHING THE UPPER 70S INLAND.
259 AM CST SAT NOV 28 2015 Pacific moisture will continue to interact with a slow moving cold front today. Temperatures from near 60 to the lower 60s ahead of the cold front will fall quickly into the 40s behind the front.
CLOUD BEARING FLOW IS NORTHERLY BUT WILL WEAKEN TONIGHT AS AN AXIS OF HIGH PRESSURE SETTLES IN. SURFACE RIDGING SAGGING SOUTH ACROSS SUPERIOR.
1220 AM EST SAT NOV 28 2015 A COLD FRONT CROSSING THE AREA WILL MOVE OFF TO THE SOUTHEAST TONIGHT.
101 AM EST SAT NOV 28 2015 RAIN AND AREAS OF DRIZZLE WILL GRADUALLY TAPER FROM NORTHWEST TO SOUTHEAST THROUGH THE EARLY MORNING HOURS AS A COLD FRONT CONTINUES TO SLOWLY WORK SOUTHWARD. SOME LOW LEVEL FRONTOGENESIS FORCING ASSOCIATED WITH THE LOW LEVEL FRONT MAY ALLOW ADDITIONAL BANDS OF LIGHT RAIN TO FORM ACROSS NORTHWEST PORTIONS OF THE AREA. THE COLD FRONT WAS BETWEEN FT WAYNE AND LIMA THIS AFTERNOON. ISENTROPIC SURFACES IN THE LOW LEVELS INDICATE DOWNGLIDE THROUGH EARLY TONIGHT. CDFNT IN ASSOCD/W NRN EXTENSION OF SPLITTING UPR TROUGH WILL SETTLE SWD ALG THE OH RVR SHRT TERM AND THROUGH THE TN VALLEY ON SUN. CNTRL ROCKIES CLOSED LOW A BIT SLWR TO OPEN AND EJECT OUT ACRS THE CNTRL PLAINS EARLY NXT WEEK AND DELAYED RAMP TO LIKELY POPS TO MON NIGHT-EARLY TUE TIMED W/NWD SURGING FNTL ZONE.
ACCENTUATING N/S GRADIENT AS NORTHERN CWA MOST LIKELY AND MORE READILY TO DECOUPLE PER PROXIMAL SOUTHERN RIDGE PERIPHERY.
The heaviest rain will remain across parts of southeast Oklahoma and west central Arkansas nearest the low level jet and consequent maximum in low level moisture transport.
1116 PM CST FRI NOV 27 2015 INCREASING CHANCES OF LIGHT SNOW AND LIGHT FREEZING DRIZZLE HEADLINE THE SHORT TERM FORECAST. THIS ACTIVE PATTERN WILL CONTINUE UNTIL THE UPPER LOW MOVES THROUGH THE AREA.
A LARGE UPPER LOW IS MOVING ACROSS EASTERN CANADA. WITH A TROUGH EXTENDING FROM THE CANADIAN MARITIMES. THIS TROUGH IS AFFECTING THE MASSIVE AREA OF HIGH PRESSURE OVER THE NORTH ATLANTIC. A PIECE OF THE HIGH PRESSURE SYSTEM REMAINS OVER THE SOUTHEASTERN UNITED STATES.
Several hours of freezing rain are now expected in parts of northeast Oklahoma tonight. /ISSUED 936 PM CST FRI NOV 27 2015/ Added Creek and Washington counties to the freezing rain advisory for tonight based on current observations and hi res model sfc temp forecast for the next several hours. however radar trends showing expanding area of light/moderate freezing rain from southwest into north central Oklahoma. Sfc freezing line running from about Copan to Oilton to Chandler right now per OK Mesonet. THE TEMPERATURE AT KBVO IS NEAR FREEZING. WE DO NOT EXPECT BUT IT IS POSSIBLE THAT A BRIEF PERIOD OF LIGHT FREEZING RAIN COULD OCCUR THERE. Thus, will keep the freezing rain advisory where it is now, but as mentioned even a one degree drop will require expansion to the southeast.
320 AM CST SAT NOV 28 2015 08z/2am surface analysis shows slow-moving cold front draped along the Ohio River, with 1037mb high pressure centered over southwest Minnesota. Due to overcast conditions and a brisk northerly breeze, have undercut MAV guidance numbers by a few degrees, resulting in high temperatures mainly in the lower to middle 40s.
TONIGHT INTO THURSDAY A BROAD SURFACE AND LOW LEVEL TROUGH WILL BECOME ESTABLISHED ACROSS THE SOUTHEAST STATES AND EXTEND INTO THE NORTHEASTERN GULF.
A WEAK TROUGH WILL CONTINUE TO BE IN PLACE OVER THE REGION AT THE SURFACE AND ALOFT AS WEAK HIGH PRESSURE RIDGES SOUTH OF THE STATE/ACROSS THE FL STRAITS. AN AREA OF LOW PRESSURE EXTENDING INTO THE NORTHERN GULF AND A RIDGE OF HIGH PRESSURE SOUTHEAST OF FLORIDA WILL CONTINUE TO PRODUCE WEST- SOUTHWESTERLY WINDS OVER THE COASTAL WATERS.
Convection is also forming a little further east in Western Lea and Eddy Counties along the thetae ridge per the HRRR and RAP13 high res models. The persistent subtropical ridge centered over the Arklatex area will shift west over the Central Plains as a trough deepens in the eastern US.
PARTICULARLY TO THE EAST OF A SFC TROF AXIS WHICH TAKES SHAPE ALONG THE NORTHERN SLOPES OF THE RATON RIDGE THROUGH KLHX. TO PERHAPS SOME POCKETS OF 1000 J/KG OR A LITTLE BETTER EAST OF THE SFC TROF AXIS ACROSS THE PLAINS. BUILDING UPPER HIGH ALOFT CUTS BACK 0-6KM SHEARS.
/ISSUED 647 AM CDT WED JUL 29 2015/ HIGH PRESSURE CONTINUES OVER THE AREA. A COLD FRONT WILL MOVE THROUGH THE AREA THIS EVENING WITH ISOLATED THUNDERSTORMS.
425 PM EDT WED JUL 29 2015 THE AVIATION SECTION HAS BEEN UPDATED BELOW A COLD FRONT WILL EXIT THE STATE LATE THIS AFTERNOON. HIGH PRESSURE IS EXPECTED TO BUILD IN THE WAKE OF THE FRONT TONIGHT.
130 PM EDT WED JUL 29 2015 HIGH PRESSURE WILL MOVE EAST OF THE AREA TODAY. A COLD FRONT WILL MOVE EAST TOWARD THE REGION THIS AFTERNOON AND EVENING.
1213 PM MDT WED JUL 29 2015 18Z TAF CYCLE EXPECT NUMEROUS TO WIDESPREAD SHRA/TSRA ACROSS NORTHERN AND CENTRAL NEW MEXICO AS THE BACK DOOR COLD FRONT PUSHES WEST.
243 PM CDT Wed Jul 29 2015 A drier and cooler airmass was spreading into extreme southeast Kansas and the Missouri Ozarks this afternoon. So far, no convection has fired along this cold front, currently at 230 PM located roughly along southern Missouri's Highway 60 corridor.
354 PM CDT WED JUL 29 2015 Post-frontal activity has diminished over the CWA as the cold front continues to push south over southern Missouri and northern Arkansas. As a result, dew points will top off in the low to mid 60's, making for much more pleasant conditions throughout the next few days.
314 PM EDT WED JUL 29 2015 A COLD FRONT WILL CROSS NRN OH/NW PA TONIGHT. HIGH PRESSURE WILL BUILD ACROSS THE LOWER OHIO VALLEY THROUGH THE WEEKEND.
201 PM EDT WED JUL 29 2015 HEAT CONTINUES THIS AFTERNOON BEFORE STRONG A COLD FRONT ARRIVES LATE TONIGHT.
325 PM EDT WED JUL 29 2015 HEAT CONTINUES THIS AFTERNOON BEFORE STRONG A COLD FRONT ARRIVES LATE TONIGHT. MODELS ARE IN REASONABLE AGREEMENT ON A WEAK COLD FRONT MOVING ACROSS THE AREA LATER TONIGHT AND THURSDAY MORNING. MODELS INDICATE MOST OF ANY CONVECTION WILL BE WITH A PREFRONTAL TROUGH WITH LITTLE ACTIVITY ALONG THE COLD FRONT ITSELF. WILL KEEP MINDS TONIGHT ON THE HIGHER SIDE OF GUIDANCE.
356 PM MDT WED JUL 29 2015 WITH STRONG RIDGING FROM NM TO THE PACIFIC NORTHWEST BY THU NIGHT. AS THE RIDGE BUILDS. HIGH PRESSURE CONTINUES TO RULE THROUGH THE END OF THE PERIOD. THE LATEST MODEL RUNS DO NOT ALLOW THE HIGH PRESSURE CENTER TO SHIFT AS FAR WEST AS PREVIOUS RUNS AS A PACIFIC TROUGH BLOCKS IT FROM THE WEST. AS A RESULT THE HIGH CENTER STAYS OVER THE CENTRAL/SOUTHERN ROCKIES WHICH IS A MORE FAVORABLE PLACEMENT FOR THE SUBTROPICAL MOISTURE PLUME TO STREAM INTO OUR FORECAST AREA.
402 PM EDT WED JUL 29 2015 A COLD FRONT WILL MOVE THROUGH TONIGHT. HIGH PRESSURE WILL BUILD IN THE MIDWEST ON THURSDAY AND A DRIER AIRMASS IS EXPECTED TO LAST INTO THE WEEKEND FOR THE OHIO VALLEY.
A COLD FRONT MOVES IN FROM THE OHIO RIVER VALLEY TONIGHT. HOWEVER, SINCE SURFACE FLOW BRIDGES ACROSS THE FRONT AND REMAINS NORTHERLY OVER THE MID STATE, CONVERGENCE IS WEAK AND THE CHANCE OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO REMAIN SOMEWHAT LOW.
