SOUTH/SOUTHEAST SURFACE FLOW IS BRINGING SLIGHTLY MORE HUMID AIR INTO THE MIDSOUTH AND TEMPS HAVE RISEN INTO THE LOWER TO MID 80S. LOWS WILL BE A LITTLE WARMER THANKS TO THE SLIGHTLY MORE HUMID AIRMASS.
The overall pressure pattern across central Illinois looks to favor dry and mostly sunny conditions today as the area remains between high pressure east of IL and elongated low pressure in the Plains. Weak warm air advection ahead of the low is generating some lift as far east of western IL, which is evident in some weak radar returns just northwest of Knox and Stark counties.
AN UPPER LEVEL TROUGH MOVING THROUGH THE AREA CONTINUES TO BRING SOME SHOWERS TO THE AREA. AN UPPER LEVEL TROUGH MOVING OVER THE AREA CONTINUES TO BRING SHOWERS TO THE AREA THIS EVENING. BUT THESE ARE MAINLY OVER THE RIDGETOPS AS. TONIGHT SKIES MAY START TO CLEAR AS THE TROUGH PULLS OUT OF THE AREA.
/issued 354 AM CDT WED SEP 16 2015/ Today will be much like yesterday as we remain under the influence of an upper ridge, anchored just SE of the CWA. Through the end of the week, the upper ridge will slowly shift south as an upper disturbance swings east through the northern states.
The seemingly permanent subtropical ridge continues to give the CWA hot and mainly dry weather. and will flatten the ridge a little.
For tonight, look for temperatures to range from the middle 60s to the lower 70s.
LATEST AVAILABLE IR IMAGERY OVERLAID WITH MODEL STREAMLINE ANALYSIS AS OF 200 PM DEPICTS THE CENTER OF A DEEP WARM ANTICYCLONE STILL OVER FAR WEST TEXAS THIS AFTERNOON. 500-200 MB TROUGH IS APPARENT IN THE SOUTHERN STREAM OVER THE TENNESSEE VALLEY. THE AXIS OF A WEAK UPPER RIDGE (AT 250 MB) IS SITUATED FROM THE NORTHERN BAHAMAS SOUTHWEST TO PINAR DEL RIO CUBA. AT THE SURFACE AND IN THE LOWER TO MIDDLE LEVELS.

A BROAD AND DEEP UPPER LEVEL TROUGH REMAINS OVER THE WESTERN US WHICH WILL KEEP US WITH COOL TEMPERATURES.
MORNING WATER VAPOR SAT LOOP AND OBJECTIVE UPPER AIR ANALYSES SHOW BROAD TROUGHING ACROSS THE PAC NW WITH MOIST SOUTHWEST FLOW OVER THE CENTRAL ROCKIES. THE BEST DYNAMIC SUPPORT LOOKS TO BE ACROSS OUR NORTHERN ZONES WHERE THE NAM/SREF HAVE HINTED AT THE HIGHEST QPF FOR THU NIGHT/FRI.
THE AXIS OF THIS TROUGH IS NOT EXPECTED TO MOVE MUCH OVER THIS PERIOD. TRANSITIONING TO COOLER MORE SEASONAL CONDITIONS. A COLD FRONTAL BOUNDARY ASSOCIATED WITH AN UPPER TROUGH LIFTING THROUGH THE NORTHERN PLAINS WILL ADVANCE SOUTHEAST ACROSS OUR CWA DURING THE DAYTIME HOURS ON THURSDAY. COOLER AIR ADVECTS SOUTH BEHIND THE FRONT THURS/THURS NIGHT WITH TEMPERATURES TRENDING COOLER WITH TIME.
Forecast lows are a degree or two warmer than what we experienced this morning, with lower 70s anticipated across west central TX. Morning clouds will give way to partly cloudy conditions Thursday afternoon with temperatures warming into the low to mid 90s.
342 PM EDT WED SEP 16 2015 HIGH PRESSURE WILL CONTINUE TO PROVIDE A VERY PLEASANT STRETCH OF WEATHER THROUGH THE SHORT TERM PERIOD WITH JUST A FEW CLOUDS TO DEAL WITH DURING THE DAY AND SOME PATCHY VALLEY FOG AT NIGHT. DEWPOINTS HAVE CREPT UP A BIT FOR MOST OF THE AREA AND THIS SHOULD KEEP TEMPS IN THE 50S FOR MOST LOCATIONS TONIGHT AND AGAIN THURSDAY NIGHT WITH RIDGE/VALLEY DIFFERENCES OF UP TO 10 DEGREES. REACHING THE LOW 80S FOR MOST OF THE AREA.
THE UPPER TROUGH OVER THE PACNW WILL SLIDE EAST OVERNIGHT. THE POLAR JET MAX WILL BE REFORMING ON THE UPSTREAM PORTION OF THE WESTERN TROUGH TOMORROW AFTERNOON AS THE LAST SIGNIFICANT PIECE OF ENERGY DROPS THROUGH IT/S BASE. THE TROUGH WILL THEN ACCELERATE ACROSS THE ROCKIES OVERNIGHT.

SURFACE COLD FRONT ORIENTED FROM THE FAR NORTHERN VALLEY SW TO S CENTRAL ND. STRONG CAPPING MAY LIMIT PCPN CHANCES SOUTH OF LOW TRACK ALONG COLD FRONT. COLD FRONT WILL PUSH EAST THURSDAY AND SHOULD BE THROUGH THE FA BY MID AFTERNOON. MUCH COOLER AIR WILL SPREAD ACROSS THE FA LIMITING HEATING SO TEMPERATURES MUCH CLOSER TO AVERAGE. EVEN COOLER ACROSS THE NW FA. WITH MUCH COOLER COLUMN IN PLACE THURSDAY NIGHT TEMPERATURES WILL DROP DOWN INTO THE 40S. SECONDARY WAVE FROM WHATS LEFT OF THE WESTERN TROUGH WILL SWING THROUGH THE CENTRAL PLAINS.
THE TIGHT MOISTURE GRADIENT WILL REMAIN NEAR THE FORECAST AREA TONIGHT WITH HIGH PRESSURE NORTH OF THE AREA WITH A LONG-FETCH ONSHORE FLOW MAINLY SOUTH OF THE AREA. PERSISTENT MID/UPPER LEVEL TROUGH ACROSS THE SOUTHEAST WILL GRADUALLY WEAKEN AND BEGIN TO LIFT OUT TO THE NORTHEAST.
ARCTIC HIGH PRESSURE CURRENTLY OVER NRN SASK WILL DVDLP SWD INTO THE AREA DURING THE DAY ON FRIDAY AND WE WILL GENERALLY SEE STEADY OR SLOWLY FALLING TMPS WITH THE LOW- LEVEL CAA ON FRI. BUT JUST HOW FAR E THE MID-LVL RIDGE FLATTENS IS STILL IN DOUBT. GIVEN THE UNCERTAINTY OF THE WARMING WILL TREND WILL TREND A BIT COOLER WITH TMPS.
A COLD FRONT NEAR THE RED RIVER WILL CONTINUE TO MOVE S TODAY. AS ANOTHER COLD FRONT MOVES S ACROSS THE REGION.
306 PM CST THU FEB 11 2016 WEAK COLD FRONT CONINTUES TO MAKE ITS WAY SLOWLY SWD UNDER NWLY FLOW ALOFT THIS AFTERNOON. WITH DEWPOINTS RECOVERING INTO THE LOW TO MID 40S TONIGHT ACROSS OUR SRN AREAS.

CLEAR SKIES AND VFR TO CONTINUE TODAY AND THROUGH THE EVENING WITH HIGH PRESSURE HOLDING OVER THE REGION. HIGH PRESSURE HAS SETTLED IN THE GULF AND THIS IS THE REASON FOR THE SOUTHERLY WINDS AND THE HIGHER DEW POINTS.
205 PM CST THU FEB 11 2016 HIGH PRESSURE AND A DRYING NORTHWEST TO NORTH FLOW WILL KEEP CENTRAL ALABAMA DRY FOR THE NEXT SEVERAL DAYS.
Temperatures have warmed sufficiently to remove the threat of freezing rain in most areas. However, very light freezing rain is possible in Salmon tonight due to cold air persisting in this area.
309 PM CST THU FEB 11 2016 THE SURFACE DATA AT 19Z SHOWED THE WARM FRONT ACROSS THE WESTERN NEBRASKA SANDHILLS. WEAK LIFT IN THE SATURATED ISOTHERMAL LAYER OVER CENTRAL AND NORTHERN NEBRASKA WILL PRODUCE LIGHT FREEZING DRIZZLE LATE TONIGHT AFTER MIDNIGHT.

A BROAD MID-UPPER LEVEL TROUGH PERSISTS ACROSS THE EASTERN HALF OF THE UNITED STATES. ANCHORED BY UPSTREAM RIDGING WEST OF THE ROCKIES.
OUTSIDE OF THE HIGH SURF, NO WEATHER RELATED HAZARDS.
HIGH PRESSURE TO OUR NORTH WILL KEEP OUR SKIES MOSTLY SUNNY TODAY WITH JUST SOME HIGH CLOUDS TO WORRY ABOUT. TEMPERATURES WILL BE CHILLY UNDER A NORTHEAST WIND WITH HIGHS IN THE LOW 30S EAST WHERE THE MOST SNOW COVER IS UP TO THE LOW 40S SOUTHWEST.
HIGH PRESSURE WILL CONTINUE TO REMAIN IN CONTROL OF NORTHERN AND CENTRAL NEVADA'S WEATHER FOR THE NEXT TWO DAYS.
This will reinforce light northeasterly surface winds during the day, with afternoon highs ranging from the upper 60s across the Big Country, to the lower and middle 70s elsewhere. An upper level northwest to west-northwest flow pattern will dominate through the next 7 days, with a ridge over the Southern Plains by next Thursday.
HIGH PRESSURE WILL REMAIN OVER THE INTERMOUNTAIN WEST THROUGH FRIDAY. THE CURRENT LARGE SCALE PATTERN CONTINUES TO BE DOMINATED BY A STRONG RIDGE CENTERED OVER THE GREAT BASIN. WHILE MILD CONDITIONS WITH MOSTLY CLEAR TO PARTLY CLOUDY SKIES WILL CONTINUE AT THE HIGHER ELEVATIONS.
COURTESY OF HIGH PRESSURE ACROSS THE SOUTHERN GREAT LAKES AND OHIO VALLEY. A SOUTHWARD PUSH AROUND THIS RIDGE AND A SOUTHERLY RETURN FLOW TRYING TO SETUP ACROSS THE GULF REGION WAS DELINEATED BY A FRONT BOUNDARY SOUTH OF HERE. A LARGER SCALE PATTERN OF RIDGING OUT WEST. AND TROUGHING EAST CONTINUED ACROSS THE GREATER NORTH AMERICAN DOMAIN. A LARGE AREA OF LOW PRESSURE OVER CENTRAL/EASTERN CANADA CONTINUED TO PRODUCE LARGE SCALE TROUGHING ALONG THE EASTERN THIRD OF THE CONUS. ACROSS THE NE PACIFIC WEST OF THE RIDGE. AN AREA OF LOW PRESSURE WAS FORMING ON THE FRONT OVER TEXAS. AND WILL BE PUSHED TO THE SOUTH BY ANOTHER COLD AREA OF HIGH PRESSURE HEADING SOUTHWARD NORTH OF THE US/CANADIAN BORDER. THIS HIGH WILL BRING DRY BUT VERY COLD CONDITIONS FOR THE UPCOMING WEEKEND.
OTHERWISE MILD TEMPERATURES AGAIN TODAY WITH LESS WIND AS THE SFC PRESSURE GRADIENT EASES AS A WEAK AREA OF HIGH PRESSURE NUDGES OVER THE REGION.
1200 PM EST THU FEB 11 2016 SNOW SHOWERS SHOULD END LATER TODAY WITH BUILDING HIGH PRESSURE. A FRIDAY COLD FRONT WILL RETURN SNOW CHANCES. BLDG HIGH PRESSURE LT TODAY/TONIGHT SHOULD BRING CLRG SKIES. THIS WAVE IS EXPD TO BE ACCOMPANIED BY A COLD FRONT LT FRI. SNOW SHOWERS SHOULD CONTINUE UNDER UPR TROFG AND LAKE/TERRAIN ENHANCEMENT FRI NGT AND SAT. BLDG HIGH PRESSURE SUN SHOULD BRING DRY WEATHER.
230 PM MST THU FEB 11 2016 PERSISTENT HIGH PRESSURE ALOFT WILL CONTINUE TO BRING MOSTLY CLEAR SKIES.
RIDGE ALOFT OVER WESTERN WYOMING FLATTENS SLIGHTLY AND MOVES SLOWLY CLOSER TO OUR FORECAST AREA. A SLOWLY WESTWARD MOVING BACKDOOR COLD FRONT WILL LIE NORTH TO SOUTH ACROSS WESTERN NEBRASKA WHERE HIGH TEMPERATURES WILL REMAIN IN THE UPPER 30S EAST OF THE COLD FRONT. THE NEARLY STATIONARY FRONT WILL LIE ACROSS WESTERN NEBRASKA OR EASTERN WYOMING AND THE MODELS ARE INDICATING SOME WEAK UPWARD VERTICAL MOTION AND QPF DEVELOPING ALONG AND EAST OF THE COLD FRONT. THUS WILL RETAIN MENTION OF LIGHT FREEZING DRIZZLE OVER PORTIONS OF WESTERN NEBRASKA FROM INHERITED GRIDS.
LIGHT SURFACE WINDS WILL SLOWLY SHIFT OUT OF THE SOUTHWEST BY THIS AFTERNOON BEFORE ANOTHER DRY COLD FRONT MOVES THROUGH LATE TONIGHT INTO EARLY TOMORROW MORNING.
AN UPPER RIDGE REMAINS OVER THE WESTERN U. THE FLOW OVER THE TOP OF THE RIDGE (AND ACROSS THE PACNW) REMAINS MOIST WITH EMBEDDED WEAK DISTURBANCES.
1028 AM PST THU FEB 11 2016 A warm front lifts into the Inland Northwest through tonight. Snow will generally fall only in the higher mountains. A cold front passes later Friday, with continued precipitation chances and slightly lower snow levels.
AND MUCH WARMER. TEMPERATURES ARE ON TRACK TO RISE TO NEAR 70 DEGREES ACROSS THE SOUTHERN COUNTIES WITH HIGHS IN THE LOW/MID 50S IN THE NORTH.
Decent northerly flow on the backside of tonight/s storm system will result in slightly cooler conditions than previously forecast.
/issued 527 AM CST THU FEB 11 2016/ /12Z TAFS/ A weak cold front will move through KABI towards noon, shifting winds to the northwest to north at 10 KTS. /issued 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.
/ISSUED 1027 AM CST THU FEB 11 2016/ WARM SWLY FLOW AT THE SFC CONTINUES AHEAD OF A COLD FRONT THAT WILL MAKE ITS WAY THROUGH OUR REGION TODAY.
THE AMPLIFIED RIDGE ACROSS THE WEST WILL GRADUALLY SHIFT EASTWARD WHILE KEEPING DRY WEATHER PATTERN ACROSS SOUTH TEXAS DURING MOST OF THE SHORT TERM PERIOD. A FEW CUMULUS WILL DEVELOP WITH MUCH LIGHTER WINDS AS MID LEVEL HIGH PRESSURE SHIFTS ITS CENTERED OVER SOUTH TEXAS FRI AFTERNOON.
213 PM MST THU FEB 11 2016 WINDS WILL CONTINUE IN THE HIGH COUNTRY INTO THIS EVENING. NO CHANGES TO PATTERN SO WILL LIKELY SEE SOME GUSTY WINDS IN THE HIGH COUNTRY TOMORROW. WE WILL BE ON THE EXTREME WEST SIDE OF THIS HIGH PRESSURE. SO SOME COOLER AIR IS EXPECTED TO SETTLE ACROSS NORTHEAST COLORADO.
LOOKS LIKE THE GULF AIRMASS PUSHING OVER THE COOLER SHELF WATERS WILL CONTAIN MAINLY LOW 60S DEWPOINTS - IN LINE WITH WATER TEMPS THERE THUS NOT EXPECTING MARINE FOG ATTM. WEAK COLD FRONT WILL APPROACH OUR FAR NORTH WITH LITTLE MORE THAN A WIND SHIFT LATE FRIDAY NIGHT.
These snow showers may possibly clip Brown county as the wave pushes into MO this evening, however given the high cloud bases and lack of deep moisture should only result in a few flurries at best. With the low stratus lifting northward this afternoon, the next wave will force the stratus shield further south again Friday morning. Increased mixing of dry air behind the cold front will help to clear some of the cloud cover over far eastern Kansas, while mostly cloudy skies are likely for the central and north central areas of the CWA.
1030 mb Canadian high pressure over the upper MS river valley and ridging over eastern IA/nw IL and northern MO will slide se across central IL this afternoon, reaching central/southern IN and eastern IL by 00Z/6 pm. Cold highs in the low to mid 20s with coldest readings from I-74 ne. 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.
351 PM CST THU FEB 11 2016 A cold front will move south across the forecast area Friday giving us a glancing blow of a very cold airmass that will settle into the Midwest and Ohio Valley.
THOUGH LEE TROFFING ALONG ALONG THE LOWER EASTERN SLOPES CONTINUES TO KEEP TEMPERATURES MILD EARLY THIS MORNING WITH CANON CITY STILL IN THE LOWER 40S WITH A WEST WIND. TEMPERATURES ALOFT BEHIND THE FRONT ARE NOT ALL THAT MUCH COOLER TODAY. MIXING WILL BE LESS AND SHOULD RESULT IN TEMPERATURES AROUND 10 DEGREES COOLER FOR THE SOUTHEAST PLAINS. LEE TROF WILL LINGER ALONG THE LOWER EASTERN SLOPES. SO WHILE LOWS OUT EAST MAY END UP A LITTLE COOLER THAN THIS MORNING.
THE COLD FRONT THAT PUSHED INTO SOUTHERN ALABAMA OVERNIGHT INTO THE MORNING HOURS TODAY HAS DEVELOPED INTO A WARM FRONT THAT IS SLOWLY MOVING NORTH TOWARDS THE BIRMINGHAM AREA. AT THE SAME TIME THE STRONG AREA OF HIGH PRESSURE CENTERED OVER IOWA AND ILLINOIS WILL MOVE EAST- SOUTHEAST. IT APPEARS FROM MODELS THAT THIS WILL PREVENT THE WARM FRONT FROM MOVING MUCH FURTHER NORTH THAN NEAR THE TENNESSEE RIVER. THIS STRONG AREA OF HIGH PRESSURE SHOULD FORCE THE WARM FRONT FURTHER SOUTHWARD AGAIN. THIS COULD PUSH HIGHS INTO THE LOWER 50S.
OVERALL PATTERN REMAINS QUITE AMPLIFIED WITH A COLD TROF APPROACHING THE NORTH CENTRAL CONUS AND A STRONG RIDGE OVER THE WESTERN STATES. LOW LEVELS MAY ALSO BECOME SATURATED ENOUGH TO SUPPORT DEVELOPMENT OF FLURRIES OR LIGHT FREEZING DRIZZLE IN OUR FAR EAST. WILL KEEP MENTION OF BOTH FLURRIES AND FREEZING DRIZZLE. COMBINATION OF ELEVATED WARMING EAST OF SFC TROF AND SOME MID LEVEL DRYING OVER TIME COULD YIELD A MIX OF LIGHT SNOW AND LIGHT FREEZING PCPN FOR OUR EASTERN PARTS FRIDAY NIGHT. PCPN WILL TAPER OFF FROM WEST TO EAST FRIDAY NIGHT AS SFC TROF SHIFTS EAST AND STRONGER/DRIER DOWNSLOPING PUSHES OFF THE FOOTHILLS. RESULTING IN A MUCH COOLER DAY TOMORROW THAN WE HAVE SEEN IN AWHILE. BILLINGS WILL SEE A RETURN OF DRIER/WARMER SW DOWNSLOPE WINDS FRIDAY NIGHT.
THIS AREA TYPICALLY FEATURES THE STRONGEST WINDS IN SOUTHERLY FLOW LIKE TODAY AND WILL ALSO NOT EXPERIENCE THE HIGHER MOISTURE WE'RE SEEING CLOSER TO THE COAST.
A warm front lifts into the Inland Northwest through tonight. Snow will generally fall only in the higher mountains. A cold front passes later Friday, with continued precipitation chances and slightly lower snow levels.
