925 PM EST WED FEB 17 2016 A COLD FRONT WILL BRING A FEW SNOW SHOWERS LATE THIS EVENING BEFORE HIGH PRESSURE BUILDS IN TONIGHT AND THURSDAY. SCT SNOW SHOWERS MAINLY S-SE OF PIT WITH A CROSSING COLD FRONT SHOULD GRADUALLY END AFTER FROPA LATE THIS EVE. BLDG HIGH PRESSURE SHOULD END ANY SNOW CHCS AND BRING A PARTIAL CLEARING TREND TWD SUNRISE. COOL HIGH PRESSURE SETTLES INTO THE REGION THURSDAY WITH CLEARING SKIES AND LIGHT WINDS EXPECTED. UPPER LEVEL RIDGE BUILDS IN THURSDAY NIGHT.
509 PM CST WED FEB 17 2016 FOR 00Z TAFS /ISSUED 235 PM CST WED FEB 17 2016/ WEAK RIDGE AXIS REMAINS POSITIONED FROM THE WESTERN GREAT LAKES THROUGH THE MID MISSISSIPPI VALLEY TO THE NORTHWESTERN GULF. THE HUNTSVILLE CWA IS ON THE SOUTHERN EXPANSE OF THIS CLOUD DECK WHICH IS ASSOCIATED WITH THE H9-H8 THERMAL TROUGH. THIS TROUGH SHOULD BE EXITING OFF TO THE EAST OVERNIGHT INTO THURSDAY AS THE MID LEVEL RIDGE AXIS BEGINS TO BUILD INTO THE REGION FOR A BRIEF PERIOD OF TIME.
627 PM EST WED FEB 17 2016 THE CENTER OF POLAR CONTINENTAL HIGH PRESSURE WILL BUILD OUT OF THE UPPER PENINSULA THIS EVENING AND ACROSS SOUTHEASTERN MICHIGAN OVERNIGHT. THIS WILL EVENTUALLY ALLOW FOR SOME OVERRUNNING OF WARMER AND MOIST AIR ALOFT WITH MID TO HIGH CLOUD EXPECTED TO THICKEN BY THURSDAY EVENING. NORTHERLY FLOW AHEAD OF THIS HIGH HAS BEEN PRODUCING LAKE EFFECT CLOUDS AND FLURRIES THIS AFTERNOON. UPPER LEVEL RIDGING WILL BEGIN WORKING ITS WAY INTO THE GREAT LAKES THURSDAY AS SURFACE FLOW CONTINUES TO VEER AROUND BACKSIDE OF DEPARTING HIGH PRESSURE.
/ISSUED 312 PM CST WED FEB 17 2016/ AN UPPER LEVEL RIDGE CONTINUES TO MOVE OVERHEAD AND WILL SHIFT NORTHWESTERLY WINDS ALOFT TO A MORE WESTERLY DIRECTION. HIGH TEMPERATURES ON THURSDAY SHOULD BE MUCH WARMER THAN USUAL.
PATCHY FOG AND POSSIBLE LIGHT FREEZING DRIZZLE IS IN THE FORECAST TONIGHT AND EARLY THURSDAY AHEAD OF A MILD THURSDAY AFTERNOON. WE CHOSE TO KEEP A SLIGHT CHANCE OF LIGHT FREEZING DRIZZLE IN THE FORECAST OVER PARTS OF CENTRAL ND TONIGHT INTO THURSDAY MORNING IN RESPECT TO THE DEEPENING MOIST LAYER BENEATH THE INVERSION SEEN ON MODEL-DERIVED FORECAST SOUNDINGS. WHICH IS SUGGESTIVE OF A VERY LOW PROBABILITY OF BONAFIDE LIGHT FREEZING RAIN NEAR THE PEAK OF THE WARM-ADVECTIVE REGIME. WE THUS ARE NOT PARTICULARLY IMPRESSED WITH FREEZING DRIZZLE RISK EVEN THOUGH IT WAS HIGH ENOUGH TO STILL INCLUDE IN THE FORECAST. FREEZING RAIN AND SNOW. TEMPERATURES WILL REMAIN NEAR THE MAGIC FREEZING THRESHOLD AND THEREFORE A MIX OF RAIN. FREEZING RAIN AND SNOW APPEARS POSSIBLE.
A BROAD TROUGH WILL MOVE ACROSS THE AREA THURSDAY AND SEND A COLD FRONT THROUGH.
LOW PRESSURE WAS LOCATED IN THE LEE OF THE ROCKIES WITH A FAIRLY TIGHT PRESSURE GRADIENT BETWEEN THE LOW OUT WEST AND THE HIGH TO THE EAST. WEAKENING SURFACE WINDS AFTER SUNSET MAY HELP THE RIDGE TO SLIGHTLY STRENGTHEN OVER THE AREA. ON THURSDAY WINDS WILL PICK UP AS THE RIDGE EXITS AND A SURFACE PRESSURE GRADIENT DEVELOPS BETWEEN THE RIDGE AND LOW PRESSURE OVER THE PLAINS.
WARM FRONT WILL REMAIN PARKED SOUTH OF IOWA TONIGHT WITH SOUTHEAST SURFACE FLOW PERSISTING OVERNIGHT. CLOUDS ALSO REMAIN PROBLEMATIC WITH THE LOW/MID CLOUDS OF EARLIER TODAY GRADUALLY DIMINISHING.
624 PM EST WED FEB 17 2016 HIGH PRESSURE WILL EXTEND ACROSS THE REGION THROUGH THE WEEKEND.
/ISSUED 322 PM CST WED FEB 17 2016/ DRY AND MILD WEATHER WILL PERSIST THROUGH THE WEEKEND AS HIGH PRESSURE MEANDERS EASTWARD ACROSS THE REGION. EXPECT TEMPERATURES TO SLOWLY WARM THROUGH THE REMAINDER OF THE WEEK AS UPPER LEVEL RIDGING BUILDS INTO THE AREA FROM THE WEST.
WEAKENING SURFACE WINDS AFTER SUNSET MAY HELP THE RIDGE TO SLIGHTLY STRENGTHEN OVER THE AREA. ON THURSDAY WINDS WILL PICK UP AS THE RIDGE EXITS AND A SURFACE PRESSURE GRADIENT DEVELOPS BETWEEN THE RIDGE AND LOW PRESSURE OVER THE PLAINS.
TYPICAL MASS OF LOW CLOUDS HOLDING IN BEHIND DEPARTING EASTERN SEABOARD UPPER TROUGH.
OVERALL FORECAST LOOKS ON TRACK WITH STRONG HIGH PRESSURE BUILDING IN NORTH OF FLORIDA TONIGHT AND THURSDAY. TEMPERATURES WILL DROP INTO THE LOW 40S OVER THE NATURE COAST.
940 PM EST WED FEB 17 2016 A COLD FRONT WILL SHIFT SOUTH OF THE REGION THIS EVENING AS HIGH PRESSURE BUILDS OVER THE REGION. THE HIGH WILL MOVE OFF THE EAST COAST THURSDAY AFTERNOON.
High pressure will prevail for the next several days.
859 PM EST WED FEB 17 2016 A DRY COLD FRONT WILL DROP SOUTHEAST TONIGHT.
537 PM CST WED FEB 17 2016 Main concern over the next few days will be wildfire danger as temperatures warm to near record values in the lower to mid 70s, and a very strong low-level jet positions over the region.
/ISSUED 230 PM CST WED FEB 17 2016/ RIDGE ALONG THE EASTERN SLOPE OF THE ROCKIES WILL PUSH EASTWARD OVER THE NEXT 24 HOURS AS LOW ALONG THE PACIFIC COAST EJECTS RAPIDLY ACROSS THE COUNTRY WITH THE MAIN PUSH OF ENERGY PASSING TO OUR NORTH LATE THURSDAY. AREAS WEST OF A TULIA TO MORTON LINE STAND THE HIGHEST PROBABILITY OF MAKING THE THREE HOUR REQUIREMENT.
1014 PM EST WED FEB 17 2016 A WEAKENING COLD FRONT WILL MOVE THROUGH CENTRAL PA THIS EVENING. HIGH PRESSURE WILL FOLLOW FOR THURSDAY WITH MORE IN THE WAY OF SUNSHINE. BUT COOLER TEMPERATURES AVERAGING SOME 5 TO 10 DEGREES BELOW NORMAL.
654 PM EST WED FEB 17 2016 SNOW SHOWERS ENDING AS UPPER LEVEL TROUGH MOVES EAST OF THE APPALACHIANS TONIGHT. FLOW DIMINISHES AS A HIGH PRESSURE BUILDS FROM THE WEST THURSDAY.
Low temps tonight will dip a few degrees cooler in areas that see clearing, especially with the light and variable winds associated with high surface pressure.
625 PM EST WED FEB 17 2016 HIGH PRESSURE AND DRY WEATHER WILL CONTINUE INTO THE WEEKEND AS HIGH PRESSURE SETTLES OVER THE REGION.
535 PM CST WED FEB 17 2016 Updated aviation section for 00z taf issuance High pressure over the middle Mississippi Valley has brought clearing as far east as the kpof area this afternoon. 19z surface dew points are at or above the low temp forecast.
831 PM EST WED FEB 17 2016 A WEAKENING COLD FRONT WILL MOVE THROUGH CENTRAL PA THIS EVENING. HIGH PRESSURE WILL FOLLOW FOR THURSDAY WITH MORE IN THE WAY OF SUNSHINE. BUT COOLER TEMPERATURES AVERAGING SOME 5 TO 10 DEGREES BELOW NORMAL.
632 PM EST WED FEB 17 2016 A COLD FRONT WILL SHIFT SOUTH OF THE REGION THIS EVENING AS HIGH PRESSURE BUILDS OVER THE REGION. THE HIGH WILL MOVE OFF THE EAST COAST THURSDAY AFTERNOON.
A LARGE AREA OF HIGH PRESSURE WILL DRIFT EASTWARD OVER THE EASTERN U.
315 PM MST WED FEB 17 2016 UPPER LEVEL WINDS HAVE BECOME SOUTHWESTERLY AS THE RIDGE AXIS SHIFTS TO THE EAST. AND START LOWERING AS A COLD FRONT APPROACHES FROM THE WEST FOR THE OVERNIGHT HOURS. THE BEST ENERGY FROM THE MAIN TROUGH WILL REMAIN TO OUR NORTH AS IT TRACKS EASTWARD ACROSS THE NORTHERN TIER STATES. BUT THE JET SWINGS AROUND THE BASE OF THIS TROUGH AND RIGHT OVER OUR FORECAST AREA DURING THE DAY. ALSO SNOW LEVELS WILL BE ON THE HIGH SIDE. AND WITH THE COMPRESSIONAL WARMING LOOK FOR AFTERNOON TEMPERATURES POSSIBLY WARMER THAN TODAY'S. SNOW WILL BE LIMITED TO THE HIGHER MOUNTAINS NEAR THE DIVIDE.
/ISSUED 600 PM EST WED FEB 17 2016/ NORTHWESTERLY UPPER FLOW FLATTENING AS WEAK UPPER-LEVEL RIDGING SHIFTS EAST INTO THE REGION THROUGH THE PERIOD.
348 AM CST THU FEB 11 2016 High pressure sinking south through the plains states will affect temperatures to the negative side over the next couple of days.
Cloud cover increases shortly after sunrise with the building high pressure overhead during the day Thursday as northerly winds weaken to around 10 mph. Highs were adjusted a few degrees from the upper 30s over east central KS to the lower 40s towards central Kansas. Cold advection on Friday as arctic high pressure builds into the Central Plains will keep highs in the mid 30s north to the mid 40s across east central Kansas.
338 AM CST THU FEB 11 2016 A backdoor cold front which slid through the region late last evening and resultant northeast surface flow will continue to draw colder air into the region today, holding high temperatures in the 20s and 30s nearly CWA-wide. Stratus over northern portions of the forecast area has struggled to spread southwestward overnight, and may allow for a few pockets of sunshine across east central KS and west central MO, possibly allowing temperatures to reach the lower 40s in those areas this afternoon. Winds will weaken progressively as high pressure drifts across northern Missouri this afternoon and into the Mississippi River valley this evening, taking the edge off the slightly below normal temperatures for the late afternoon and evening hours.
LOWS TONIGHT WILL BE ABOUT 2 TO 3 DEGREES WARMER THAN LAST NIGHTS VALUES. THIS IS PRIMARILY DUE TO A SHIFT IN THE LOW LEVEL FLOW FROM A PREDOMINATELY NW DIRECTION LAST NIGHT TO A MORE E/SE TONIGHT. THEN AS HIGH PRESSURE BEGINS TO BUILD INTO THE REGION WINDS TRANSITION TO A MORE NE DIRECTION.
BY THIS AFTERNOON EXPECTING ONLY HIGH CLOUDS WITH TEMPERATURES SLIGHTLY COOLER COMPARED TO YESTERDAY. AS THE MOISTURE GRADUALLY DEEPENS FRIDAY NIGHT AREAS OF FREEZING FOG AND FREEZING DRIZZLE WILL DEVELOP. WITH A CHANCE FOR LIGHT FREEZING RAIN WHERE MOISTURE GETS TO AROUND 1KM IN DEPTH.
347 AM CST THU FEB 11 2016 (Today and Tonight) A weak cold front will move south across the Big Country during the morning hours, reaching the I-20 corridor around noon, and a San Angelo to Brownwood line late afternoon. In the Concho Valley, and areas south and east, the cold front will have little effect with highs expected in the upper 70s to lower 80s! Winds will become light tonight as the weak front dissipates.
355 AM CST THU FEB 11 2016 Cold front currently passing through the area which will push temps nearer seasonal normals. Near persistent conditions continue on Friday ahead of a stronger cold front which will pass through the area on Friday.
COLD AIR WILL AGAIN MOVE SOUTH AND WESTWARD AS HIGH PRESSURE BEGINS TO SINK INTO THE NORTHERN PLAINS. BUT MOIST PROFILES THROUGH ABOUT 5KFT INDICATE TYPE SHOULD BE RAIN/SNOW RATHER THAN FREEZING RAIN. BUT THEN AN INTRUSION OF WARM AIR ALOFT COULD MEAN PRECIP CHANGES TO FREEZING DRIZZLE/RAIN AFTER MIDNIGHT.
838 PM PST WED FEB 10 2016 HIGH PRESSURE ALOFT AND WEAK OFFSHORE FLOW LEAD TO ANOTHER UNSEASONABLY WARM DAY ACROSS SW CA.
A WARM FRONT WILL SPREAD RAIN NORTHWARD ACROSS THE AREA ON THURSDAY. THE ASSOCIATED WEAK COLD FRONT WILL MOVE EAST ACROSS THE AREA FRIDAY MORNING.
A CLIPPER LOW PRESSURE SYSTEM IS FORECAST TO DEVELOP OVER LAKE SUPERIOR TONIGHT. AN ASSOCIATED COLD FRONT WILL MOVE INTO FAR NORTHERN WI LATE TONIGHT.
A QUIET WEATHER PATTERN WILL PREVAIL THROUGH FRIDAY WITH UPPER-LEVEL RIDGING REMAINING IN PLACE. SURFACE TEMPERATURES MAY BE A BIT COOLER THAN TODAY WITH MID/HIGH CLOUD EXPECTED TO DRIFT ACROSS THE CWA DURING THE AFTN HOURS WITHIN NORTHWEST FLOW ALOFT. WENT AHEAD AND ADDED PATCHY LIGHT FREEZING DRIZZLE ALONG A SIDNEY-ALLIANCE LINE.
HIGH PRESSURE WILL REMAIN THE DOMINANT WEATHER FEATURE OVER THE INTERMOUNTAIN WEST THROUGH THE END OF THE WEEK. WITH A LARGE RIDGE ACROSS THE WEST.
2-3 MB/2-HR PRESSURE RISES AND MODEST COLD ADVECTION IN THE LOW-LEVELS ARE CURRENTLY BEING OBSERVED OVER ERN NEB AND WRN IA. THIS SYSTEM WILL ALLOW FOR ARCTIC HIGH PRESSURE TO BUILD INTO THE MID MO RVR VALLEY FRI NIGHT/SAT MRNG WITH BELOW NORMAL TMPS.
321 AM EST THU FEB 11 2016 WEAK LOW PRESSURE WILL CROSS THE REGION TODAY IN ADVANCE OF AN ARCTIC FRONT THAT WILL CROSS THE REGION THIS AFTERNOON.
The official forecast leaned on the cooler end of the guidance given the seemingly favorable setup. The region will remain under deep west-northwesterly flow on the southwestern flank of a broad trough, and a warm air advection pattern. By Friday, it looks like TLH should record its first day with an above-normal average temperature in about a week with highs in the low-mid 70s in many locations. A dry cold front should push through the area Friday Night.
GIVEN THE WARMER START AND THE CONTINUED SSWLY LOW LEVEL WINDS.
However with sub freezing temps, we'll keep hitting the SPS and graphical nowcasts hard for any isolated issues that may crop up on the work/school commute home. We see another similar clipper type system affect the lower Ohio River Valley Friday.
333 AM CST THU FEB 11 2016 A BACKDOOR COLD FRONT HAS USHERED IN STRATUS ACROSS THE NORTHEASTERN HALF OF THE FA. SOME LIGHT FOG INDICATED AT THEDFORD AND PINE RIDGE AS OF 08Z. THERE COULD BE SOME VERY LIGHT PRECIPITATION AFTER MIDNIGHT AND SOUNDING PROFILES FAVOR SOME CHANCE FOR FREEZING DRIZZLE. ARCTIC HIGH PRESSURE WILL BUILD SOUTHEAST ACROSS THE NORTHERN PLAINS ON FRIDAY AND WILL FORCE A FRONT SOUTHWEST ACROSS THE SANDHILLS. THE FORECAST CALLS FOR MUCH COOLER TEMPERATURES FRIDAY AFTERNOON. TO NEAR 40 OVER THE HIGHEST TERRAIN OF THE SOUTHWEST. BUT INTO THE OVERNIGHT SOUNDINGS FAVOR MORE LIGHT FREEZING DRIZZLE OVER SNOW.

1226 AM EST THU FEB 11 2016 VFR CONDITIONS THROUGH THE NEXT 24 HOURS DUE TO DRY AIR ASSOCIATED WITH HIGH PRESSURE OVER FLORIDA.
HIGH PRESSURE WAS CENTERED OVER CENTRAL MINNESOTA WITH THE LOW CLOUDS OVER THE WESTERN EDGE OF THE HIGH AND EAST OF A BAROCLINIC ZONE OVER WESTERN NEBRASKA. COLDER AIR THEN MOVES IN BEHIND THIS SYSTEM TONIGHT INTO FRIDAY AS MAIN CORE OF ARCTIC HIGH PRESSURE MOVES TOWARD THE LOWER MISSOURI VALLEY.
A WEAK COLD FRONT WILL CONTINUE TO CAUSE A WIND SHIFT AS IT MOVES ACROSS THE AREA OVERNIGHT. A DRY COLD FRONT WILL MOVE THROUGH THE AREA AS WELL TONIGHT. A COLD FRONT WILL MOVE THROUGH THE AREA TONIGHT BRINGING NORTH WINDS TO THE AREA. COOLER WEATHER IS EXPECTED TOMORROW ALTHOUGH TEMPERATURES WILL REMAIN NEAR OR UPPER CLIMO. THE PRECIPITATION CHANCES WILL BE THIS WEEKEND AS A TROUGH MOVED FROM THE NORTHERN ROCKIES SOUTHEAST INTO THE CENTRAL PLAINS. PRECIP CHANCES WILL INCREASE ALONG WITH THE ASSOCIATED COLD FRONT WITH THE HIGHEST PRECIP CHANCES IN THE SOUTHEAST.
1253 AM EST THU FEB 11 2016 HIGH PRESSURE WILL BUILD EAST FROM THE LOWER GULF COAST REGION THROUGH TONIGHT. HIGH PRESSURE ON THURSDAY WILL GIVE WAY TO A WEAK AREA OF LOW PRESSURE AND ASSOCIATED COLD FRONT THURSDAY NIGHT.
238 AM CST THU FEB 11 2016 A WEAK COLD FRONT WILL ENTER NORTH TEXAS TODAY AND BRING SLIGHTLY COOLER AND DRIER AIR. TEMPERATURES FRIDAY WILL BE 5 TO 10 DEGREES COOLER THAN THURSDAY AND WIND SPEEDS WILL BE SLIGHTLY STRONGER.
332 AM CST THU FEB 11 2016 HIGH PRESSURE WILL DOMINATE THE FORECAST KEEPING MOST OF THE REGION DRY AND COOL WITH RELATIVELY LIGHT WINDS.
Winds will veer to the west-southwest by mid-morning as a cold front approaches the I-20 corridor. A cold front will move into the Big Country during the morning hours, shifting winds to the north at KABI, eventually reaching KSJT and KBBD by late afternoon. This will result in slightly warmer temperatures across much of the area, with overnight lows in the upper 30s and lower 40s. Wind speeds will be lighter across southern counties, with overnight lows mainly in the lower and middle 30s along the I-10 corridor. On Thursday, a weak cold front will move south across the Big Country during the morning hours and will drift south to roughly a San Angelo to Brownwood line by late afternoon. The only noticeable effect from the front will be a wind shift to the north and cooler temperatures behind the front.
Deep long wave trough over the eastern U. in fact light and variable underneath the high center by late afternoon as it becomes centered roughly over Springfield. Models have sped up the approach of the quick clipper-like system out of the NW and into the long wave trof over the eastern half of the country. Deep trof over the eastern half of the country will continue to dominate the weather through the end of the week, keeping the colder air over the region.
THE UPPER PATTERN WILL REMAIN STAGNANT WITH AN UPPER RIDGE OVER THE GREAT BASIN AND TROUGH OVER THE EAST COAST. LACK OF MIXING AND SLIGHTLY COOLER AIR IN PLACE ACROSS THE REGION WILL ONLY ALLOW AFTERNOON HIGHS TO REACH INTO THE LOWER TO MID 60S ACROSS THE PLAINS. MOZLEY UPPER HIGH REMAINS OVER THE GREAT BASIN FRIDAY WITH DEEP UPPER TROUGH OVER THE GREAT LAKES.
A ridge of high pressure will continue to dominate the weather pattern the next couple of days. Friday/Friday night a slightly stronger but still dry system for the interior will move through and breaks down the ridge to help bring a slight cooling trend through Friday.
255 AM EST THU FEB 11 2016 HIGH PRESSURE MOVES IN THURSDAY NIGHT.
STARTING TO SEE SOME HIGHER LEVEL CLOUDS MASKING THE LOWER ONES SO HOPEFULLY NO OTHER AREAS WILL DROP LIKE THE LANGDON AREA.
THIS HIGH WAS PRODUCING CLEAR SKIES AND LIGHT WINDS. THE TEMPERATURES FOR THAT ANALOG WAS ACTUALLY MUCH WARMER /-8C THEN AND TO -20 THIS TIME/ FOR US THAN DURING THAT ARCTIC OUTBREAK.
WITH EXCELLENT MODEL AGREEMENT IN THE NEAR SHORT TERM SHOWING GOOD CHANCES FOR A FREEZING RAIN AND SNOW MIX TONIGHT FOLLOWED BY ACCUMULATING SNOW EARLY THURSDAY MORNING. THIS FEATURE WILL BRING WITH IT SOME LIGHT SNOW WHICH MAY BEGIN AS A PERIOD OF FREEZING RAIN AND/OR A WINTRY MIX. LOW STRATUS MAY ALSO PRODUCE FREEZING FOG CONDITIONS AS WELL. COOLER TEMPERATURES WILL REMAIN IN PLACE FOR FRIDAY ACROSS MUCH OF THE REGION WITH FRONT OFF TO THE WEST.
A COLD FRONT WILL SLOWLY SINK SOUTH INTO AND THROUGH THE FORECAST AREA DURING THE COURSE OF TODAY AND INTO TONIGHT. LOW LEVEL SOUTHERLY FLOW AHEAD OF THE FRONT WILL AID IN PROMOTING WARMER CONDITIONS ACROSS THE FORECAST AREA TODAY. LOOK FOR HIGHS THIS AFTERNOON UNDER MOSTLY SUNNY SKIES TO TOP OUT FROM THE UPPER 50S IN THE NORTH ALONG THE HIGHWAY 82 CORRIDOR. TO THE MIDDLE 70S IN THE SOUTH ALONG THE HIGHWAY 84 CORRIDOR. LOWS TONIGHT WILL RANGE FROM THE LOWER 30S TO AROUND 50. HIGH PRESSURE CENTERED OVER THE UPPER MISSISSIPPI RIVER VALLEY WILL SURGE SOUTH INTO THE FORECAST AREA FRIDAY NIGHT.
The low will continue to shift south overnight into Thursday morning. Winds will be light and variable overnight and will then shift to a northerly direction on Thursday as the low shifts south. Since the low level thermal ridge is getting suppressed to the south and west of our area. highs will be considerably cooler than today across E OK. A weak cold front will push through later tonight with a shift to north winds for Thursday, resulting in a modest cool down to afternoon highs near normal. Temps will then rebound some on Friday ahead of a much stronger Canadian cold front, which will move into northern areas Friday afternoon and the rest of the area Friday night.
HIGH PRESSURE WILL BUILD INTO THE REGION TODAY KEEPING DRY WEATHER OVER THE FORECAST AREA. TEMPERATURES WILL BE CLOSE TO NORMAL LEVELS TODAY WITH HIGHS FROM THE LOWER 40S TO MID 50S.
THESE CLOUDS HAVE KEPT TEMPERATURES A BIT COOLER THAN EXPECTED IN SOME AREAS. TEMPERATURES WILL BE A BIT COOLER ACROSS AREAS THAT WERE CLOSE TO 60 BUT STILL ABOVE NORMAL.
EXPECT TEMPERATURES TO RAPIDLY FALL BACK BELOW FREEZING THIS EVENING AS THE SUN GOES DOWN. EXPECT LITTLE SHIFT IN THE OVERALL SYNOPTIC PATTERN THROUGH THE SHORT TERM PERIODS AS NORTHWESTERLY FLOW ALOFT WILL CONTINUE WITH A WEAK UPPER LEVEL WAVE MAKING ITS WAY OVER THE TOP OF THE UPPER LEVEL RIDGE AND TOWARDS THE LOCAL AREA TOMORROW AFTERNOON. AS THE LOW LEVEL FLOW TURNS MORE EASTERLY AND THEN SOUTHEASTERLY OVERNIGHT. BRINGING SIGNIFICANT LOW LEVEL STRATUS AND COOLER TEMPERATURES BACK TOWARDS THE REGION TOMORROW. LOW PRESSURE OVER THE HUDSON BAY AREA KEEPS THE ERN CONUS UNDER BROAD TROUGHING. WHILE A RIDGE OF HIGH PRESSURE EXTENDS NORTH THROUGH THE ROCKIES. THE MAIN STORY THROUGH FRIDAY LIES WITH THE PASSAGE OF A COLD FRONT.
A weak cold front will try to push through the northern terminals during the day Thursday and result in a wind shift to the north and northwest.
SOUTH TO SOUTHWEST LOWER LEVEL FLOW INTO THE TROUGH CONTINUES THE WARMER. A WEAK COLD FRONT SAGS INTO CENTRAL TEXAS ON FRIDAY. SLIGHTLY COOLER TEMPERATURES ARE EXPECTED FOR CENTRAL TEXAS ON FRIDAY WITH LITTLE CHANGE ELSEWHERE.
At this time, the highest chances look to be across southern Indiana south toward central Kentucky, where a few tenths of an inch are possible. 5 to maybe 1 inch report isn't out of the question, but that is on the high end of probability.
328 AM EST THU FEB 11 2016 HIGH PRESSURE WILL DOMINATE INTO THE WEEKEND.
WITH SURFACE RIDGING STILL OVER THE GULF. EVEN THOUGH SOME CLOUDINESS WILL BE POSSIBLE TODAY AND TONIGHT AS THE LOW MOVES ALONG THIS SURFACE BOUNDARY ACROSS THE SOUTHERN STATES TODAY. EXPECT MILDER TEMPERATURES TODAY AND TONIGHT AS THE LOW MOVES ACROSS. THE FRONT IS EXPECTED TO MEANDER SLOWLY TO THE SOUTH THROUGH TONIGHT AS A STRONG RIDGE SINKS SOUTHWARD OUT OF CENTRAL CANADA INTO THE DAKOTAS.
A WEAK COLD FRONT CONTINUES TO MOVE FURTHER SOUTH AND SHOULD SHIFT WINDS TO A MORE NORTHERLY DIRECTION AT KDHT AND KAMA WITHIN THE NEXT SEVERAL HOURS. A WEAK COLD FRONT HAS ALREADY MOVED THROUGH KGUY AND SHIFTED WINDS TO A MORE NORTHERLY DIRECTION. SURFACE WINDS ARE EXPECTED TO SHIFT BACK OUT OF THE SOUTH BY THURSDAY EVENING AHEAD OF YET ANOTHER COLD FRONT BACKDOORS INTO THE PANHANDLES LATE THURSDAY NIGHT INTO FRIDAY MORNING.
WITH LOCATIONS ALONG AND SOUTH OF THE HAL ROGERS PARKWAY AND HIGHWAY 80 CORRIDOR MAXING OUT IN THE LOWER 30S. THE COLD WEATHER WILL CONTINUE TONIGHT AS THE MERCURY PLUMMETS INTO THE LOW TO MID TEENS ACROSS EASTERN KENTUCKY DUE TO THE INFLUENCE OF NORTHWEST FLOW ON THE BACK SIDE OF A DEPARTING TROUGH OF LOW PRESSURE ALOFT THAT WILL BE INFLUENCING OUR WEATHER FOR THE NEXT COUPLE OF DAYS. HIGHS ON FRIDAY SHOULD BE A BIT WARMER THAN TODAY.
811 PM PST WED FEB 10 2016 High pressure weakens over the next couple of days, allowing for increasing precipitation chances. A warm front Thursday, followed by a cold front passage Friday, will produce light valley rain and high mountain snow across much of the region.
WITH LOCATIONS ALONG AND SOUTH OF THE HAL ROGERS PARKWAY AND HIGHWAY 80 CORRIDOR MAXING OUT IN THE LOWER 30S. THE COLD WEATHER WILL CONTINUE TONIGHT AS THE MERCURY PLUMMETS INTO THE LOW TO MID TEENS ACROSS EASTERN KENTUCKY DUE TO THE INFLUENCE OF NORTHWEST FLOW ON THE BACK SIDE OF A DEPARTING TROUGH OF LOW PRESSURE ALOFT THAT BE INFLUENCING OUR WEATHER FOR THE NEXT COUPLE OF DAYS. HIGHS ON FRIDAY SHOULD BE A BIT WARMER THAN TODAY. SHOULD BEGIN TO SCATTER OUT BY 15 OR 16Z AS A COLD RIDGE OF HIGH PRESSURE TEMPORARILY SETTLES OVER THE REGION.
1033 PM MST WED FEB 10 2016 06Z TAF CYCLE A SLIGHTLY WEAKENED BUT STILL ROBUST UPPER RIDGE REMAINS SPRAWLED FROM BAJA CA NORTH INTO THE WESTERN GREAT BASIN KEEPING A LIGHT TO OCCASIONALLY MODERATE NW FLOW OVR NM.
IN COMBINATION WITH EASTERLY WINDS COULD CAUSE AREAS OF FOG AND PATCHY FREEZING DRIZZLE IN THE WESTERN CWA TONIGHT. BUT WILL NEED TO MONITOR THE WESTERN EDGE OF THE SNOW WHERE ICE COULD BE LOST IN THE DENDRITIC GROWTH ZONE WHICH COULD CAUSE FREEZING DRIZZLE ISSUES. AN ARCTIC HIGH PRESSURE WILL BUILD INTO THE REGION ON FRIDAY WITH 925 MB TEMPS FALLING THROUGH THE DAY.
312 AM CST THU FEB 11 2016 An upper level trough is over the eastern conus with an upper level ridge over the western conus. A cold front will move into the area today resulting in slightly cooler temperatures from yesterday.
VEERING WESTWARD LATER ON THURSDAY AHEAD OF A WEAK COLD FRONT WHICH WILL ARRIVE AROUND MIDDAY AT TXK/ELD AND THEN BY MID TO LATE AFTERNOON ALONG THE I-20 TERMINALS. /ISSUED 955 PM CST WED FEB 10 2016/ TWEAK A FEW OVERNIGHT LOWS A FEW SITES WITH CALM WINDS ARE RUNNING COOLER THAN SHOULD BE FOR FORECAST LOWS TO HOLD OUT UNTIL DAYBREAK.
HIGH PRESSURE WILL MOVE IN BEHIND THE FRONT ON FRIDAY.
