MAINLY DUE TO MORNING SUNSHINE AND NEUTRAL ADVECTION AHEAD OF THE ACTUAL COLD FRONT STILL NEAR MEMPHIS AREA. DUE TO THE DRY BOUNDARY LAYER IN PLACE AND SUBSIDENCE BEHIND THE PRE-FRONTAL TROUGH. BUT WITH TEMPERATURES IN THE LOWER 40S AND DEWPOINTS DROPPING INTO THE LOWER 20S TO UPPER TEENS. AFTER A FEW HOURS OF DRY CONDITIONS WITH A CEILING ON THE LOWER END OF THE VFR RANGE.
A building ridge of high pressure will dominate the weather this week. Today, high clouds continue to stream over the ridge causing the mostly cloudy skies. As the ridge slowly moves east and strengthens, expect the cloud cover to decrease tonight, causing mostly clear skies. Valley inversions will strengthen under the influence of the ridge causing fog and stratus in western Montana valleys and near Salmon, ID.
858 AM PST MON FEB 8 2016 HIGH PRESSURE AND GUSTY OFFSHORE WINDS WILL BRING WELL ABOVE NORMAL TEMPERATURES THIS WEEK WITH POSSIBLE RECORD TEMPERATURES TODAY AND TUESDAY. THE HIGH WILL WEAKEN AT THE END OF THE WEEK FOR A COOLING TREND.
1155 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.

A HIGHLY AMPLIFIED PATTERN IS IN PLACE ACROSS THE CONUS THIS AFTERNOON FEATURING A STRONG RIDGE OVER THE WEST AND A DEEP TROUGH IN THE EAST. FORTUNATELY WE ARE BEING INFLUENCED MORE BY THE RIDGE AND THAT WILL REMAIN THE CASE FOR THE NEXT SEVERAL DAYS AS IT BEGINS TO MIGRATE OUR DIRECTION. THIS FEATURE WILL REMAIN WELL SOUTH OF US ALLOWING MOSTLY SUNNY SKIES AND WARMER THAN NORMAL TEMPS TO CONTINUE WITH READINGS CLIMBING FROM SEASONAL NORMS TODAY TO AS MUCH AS 6 TO 9 DEGREES ABOVE NORMAL BY THE WEEKEND. EACH ONE HINTS AT A ANOTHER BACK DOOR COLD FRONT FOR MONDAY.
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. The main energy associated with the upper level trough begins to move eastward out of our region on Tuesday.

1044 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.
DRY AND MUCH WARMER THIS WEEK WITH AFTERNOON HIGHS WELL ABOVE AVERAGE FOR FEBRUARY. STRONG HIGH PRESSURE WILL CONTINUE TO DOMINATE OUR WEATHER INTO THE COMING WEEKEND. DRY AND MORE DRY WITH ONLY SOME PATCHES OF CIRRUS ON THE NORTHERN FRINGE OF A WEAK DISTURBANCE DIRTYING UP THE BASE OF THE RIDGE TO OUR SOUTH. WITH THIS LARGER SCALE PATTERN THE RIDGE IS GOING TO BE RATHER STUBBORN FOR SEVERAL DAYS WITH SE AZ ON THE PROTECTED FRONT FLANK OF THE RIDGE. ECMWF ENSEMBLE MEAN AND SPREAD TRENDS AT 200-240 HOURS CONTINUE TO REASONABLY SHOW THE RESULTING TRANSITION WITH THE THE GEFS SUBSEQUENTLY CONTINUING TO SHOW A FAVORABLE CONSOLIDATION OF THE 500MB 5760M ISOBAR INTO A TROUGH AND THEN ZONAL CONFIGURATION AT 240- 312 HOURS. HIGH PRESSURE WILL BRING DRY CONDITIONS WITH WELL ABOVE AVERAGE HIGH TEMPERATURES THIS WEEK.
1252 PM EST MON FEB 8 2016 A COLD FRONT WILL MOVE THROUGH LATE THIS AFTERNOON AND EVENING.
HIGH A SURFACE FRONT/TROUGH IS CURRENTLY DROPPING SOUTH THROUGH THE STATE AND WILL MOVE THROUGH SOUTHERN WISCONSIN LATE AFTERNOON AND EVENING. SATURATION AND WEAK LIFT WILL LINGER THROUGH TUESDAY AS THE UPPER TROUGH SLOWLY HEADS EASTWARD. TEMPS TOMORROW WILL BE SEVERAL DEGREES BELOW NORMAL BEHIND THE DEPARTING TROUGH.
TUESDAY TEMPS WITH CONTINUED STRONG CAA WILL LEAD TO HIGHS A FEW DEGREES COOLER THAN TODAY WITH READINGS ONLY REACHING THE UPPER SINGLE DIGITS.
A NEARLY STACKED LOW PRESSURE SYSTEM WILL MOVE EAST ACROSS THE GREAT LAKES. THE LOWEST AMOUNTS WILL GENERALLY BE IN THE SOUTHWEST. A FEW OF THE HIGHER ELEVATIONS IN THE SOUTHEAST COULD SEE LOCALIZED AMOUNTS AROUND 6 INCHES. AS THE UPPER LEVEL LOW START TO WEAKEN AND THE SYSTEM LIFTS OUT TO THE NORTHEAST.
THE HIGHEST CONCERN IS THE FAR SOUTHWEST WHERE 1 TO 2 INCHES OF SNOW THIS AFTERNOON COMBINED WITH GUSTY WINDS PUTS THIS AREA AT GREATEST RISK FOR A POSSIBLE WINTER WEATHER ADVISORY FOR BLOWING SNOW WITH VISIBILITIES AROUND ONE HALF MILE. THE EXCEPTION WILL BE ACROSS THE HIGHER TERRAIN IN THE FAR SOUTHWEST CLOSEST TO THE BAROCLINIC ZONE AND STRONGER OMEGA/VERTICAL MOTION.
812 AM EST MON JAN 11 2016 FAST MOVING LOW PRESSURE WILL SPREAD SNOW OVER THE REGION LATE TONIGHT AND TUESDAY. DRY AMBIENCE AND SHRTWV RIDGING SHOULD PROVIDE SOME COLD SUN FOR THE REMAINDER OF THE DAY. BY TONIGHT CLOUDS WILL BE ON THE INCREASE AS LOW PRESSURE DVLPS RAPIDLY OVR THE GREAT LAKES. A COLD FRONT ASSOCIATED WITH THAT LOW IS PROJECTED ACRS THE AREAS ON TUESDAY. LOWERING INVERSIONS AND A DRY AIRMASS WILL ALSO KEEP A LID ON UPSLOPE AMOUNTS FOR THE RIDGES. TOTAL SNOWFALL OUTSIDE THE RIDGES AND I-80 CORRIDOR WILL BE 1-2 INCHES. WITH 3-4 INCHES NORTH OF I-80 AND IN THE HIGHER ELEVATIONS.
BRIEF PERIODS OF MVFR CIGS/VSBYS WILL BE ON THE INCREASE THIS AFTERNOON AND TONIGHT AS RAIN CHCS INCREASE DUE TO THE COMBINATION OF A COASTAL TROUGH AND AN UPPER LEVEL DISTURBANCE AND INCREASING MOISTURE. AN UPPER LEVEL LONG WAVE TROUGH DRAPED FROM THE DESERT SW TO THE E U. MAINLY ALONG THE COAST AND OVER THE WATERS WHERE THE COASTAL TROUGH WILL PROVIDE LOW LEVEL CONVERGENCE.
510 AM CST MON JAN 11 2016 PATCHY FREEZING FOG WILL CAUSE FORECAST CONFIDENCE TO BE LOW FOR THE START OF THE 12Z TAF CYCLE. KAMA IS THE ONLY TERMINAL BEING IMPACTED BY THE FREEZING FOG BUT THE FOG IS IN THE VICINITY OF KDHT. HOWEVER WEAK MOIST AIR ADVECTION ABOARD SOUTH/SOUTHWEST WINDS AHEAD OF THE TROUGH AXIS CONTINUES TO MAINTAIN SOME STRATUS AND PATCHY FREEZING FOG ACROSS THE REMAINDER OF THE PANHANDLES. LINGERING DEEPER SNOW COVER ACROSS PARTS OF THE NORTHERN PANHANDLES WILL LIKELY HOLD TEMPS IN THE LOWER 40S TODAY.
Early this morning, water vapor imagery showed a weak embedded wave within the broad mid-level trough skimming southeastward across Nebraska. At the surface, the region was wedged between high pressure over the southeastern U. and low pressure across the Dakotas and Nebraska, resulting in southwesterly winds early this morning. As a result, most locations saw temperatures increasing early this morning into the low/mid 20s.
/ISSUED 348 AM CST MON JAN 11 2016/ OPEN AND SHEARING TROUGH IN NW FLOW WAS BISECTING THE REGION THIS MORNING WITH LITTLE FANFARE TO NOTE. AS THIS TROUGH AXIS DEPARTS LATER THIS MORNING. A WINDOW OF OPPORTUNITY EXISTS FOR SOME FREEZING FOG AND STRATUS IN OUR W-NW COUNTIES THROUGH MID-MORNING. MODELS CONTINUE TO SHEAR OUT THE TROUGH MENTIONED ABOVE AND TRY TO DEVELOP A CLOSED LOW OVER NORTHERN MEXICO.
HIGH PRESSURE IS CENTERED AROUND THE ARKLATX THIS MORNING WITH TEMPERATURES AWAY FROM THE COAST GENERALLY NEAR OR BELOW FREEZING. THROUGH TODAY AND TUESDAY, THE RIDGE AT THE SURFACE WILL GRADUALLY MOVE SOUTH WHILE WEAK LOW PRESSURE DEVELOPS IN THE GULF IN RESPONSE TO THE APPROACHING SHORT WAVE. A FEW SHOWERS MAY AFFECT THE COASTAL ZONES TONIGHT, BUT AS THE RIDGE MOVES CLOSER THE LOW WILL SHIFT SOUTH AS WELL PUSHING THE SHOWERS FARTHER INTO THE GULF TUESDAY MORNING.
622 AM EST MON JAN 11 2016 HIGH PRESSURE OVER THE CENTRAL CONUS WILL GRADUALLY BUILD EAST INTO THE REGION TODAY. A REINFORCING COLD FRONT WILL CROSS THE AREA TUESDAY WITH DRY AND COOL CONDITIONS PREVAILING THROUGH THE END OF THE WORK-WEEK. AS HIGH PRESSURE. CURRENTLY CENTERED OVER THE LOWER MISSISSIPPI VALLEY. A BROAD UPPER LEVEL TROUGH WILL SWING TOWARDS THE AREA ON TUESDAY. WINDS MAY ONCE AGAIN BECOME GUSTY DURING THE AFTERNOON ON TUESDAY AHEAD OF THE NEXT COLD FRONT.
1005 AM EST MON JAN 11 2016 HIGH PRESSURE WILL BUILD SOUTH OF THE AREA TODAY AND TONIGHT. A DRY COLD FRONT WILL APPROACH FROM THE WEST TUESDAY AND CROSS THE REGION TUESDAY NIGHT.
1010 AM EST MON JAN 11 2016 HIGH PRESSURE WILL BUILD INTO THE REGION TODAY AND PERSIST INTO LATE WEEK.
640 AM EST MON JAN 11 2016 HIGH PRESSURE WILL MOVE EAST OF THE REGION TODAY. AN ARCTIC COLD FRONT WILL APPROACH FROM THE NORTHWEST TONIGHT AND SWING ACROSS THE AREA TUESDAY MORNING.
/ISSUED 330 AM CST MON JAN 11 2016/ High pressure ridge will continue to moderate as it slides east and south today. which means a warmer start to the work week.
A WEAK SYSTEM WILL TRACK TO THE NORTH OF OUR AREA TODAY WITH WEAK RIDGING TAKING PLACE OVER THE REGION.
THE APPROACH OF AN UPPER TROUGH OF LOW PRESSURE PROVIDING LOWERING OF CLOUDS FROM HIGH BETWEEN 25-30 KFT DOWN TO MIDDLE LEVEL OF 10-15 KFT DURING THE DAY TODAY THEN CLEARING INTO THE EARLY EVENING. UPPER TROUGH THAT BROUGHT THE CLOUDS TO SHIFT EAST OVERNIGHT ALLOWING FOR UPPER-LEVEL RIDGE TO BUILD ACROSS MOST OF THE CENTRAL CONUS. TEMPERATURES OVERNIGHT TO FALL TO NEAR FREEZING ACROSS THE REGION.
MODELS ALSO HAVE BEEN BACKING OFF ON WIND SPEEDS ON BACK SIDE OF ASSOCIATED SURFACE COLD FRONTAL PASSAGE SO MINIMAL WIND IMPACTS EXPECTED.
A broad upper level trough continues to be situated across much of central and eastern North America with northwesterly flow from western Canada into the Plains and Midwestern states. Only some scattered mid level clouds are expected with the wave, along with a weak shot of cooler air across central and parts of western Kansas today. Through mid-week, an upper level ridge over the western states will move east over the central Plains.
433 AM MST MON JAN 11 2016 A WEAK SHORT WAVE TROUGH ALOFT SWEEPS THROUGH NEBRASKA AND KANSAS TODAY WITH ONLY AN INCREASE IN CLOUDS EXPECTED.
SOUTH TEXAS WILL TRANSITION TO A WETTER PERIOD AS SFC COASTAL TROUGHING DEVELOPS. H5 TROUGH CURRENTLY ACROSS NM AND THE TX PANHANDLE WILL DIVE SOUTHEAST TODAY. THIS WILL INDUCE SFC COASTAL TROUGHING JUST OFFSHORE DURING THE DAY. RAINFALL EASES A BIT LATER TUESDAY AS THE TROUGH STRETCHES AND DRIFTS BACK TO THE WEST. TEMPS WILL AGAIN ONLY REACH THE LOWER 60S.
Freezing fog has also been observed in many of the cold places. Some of the cloud cover is spreading out and dissipating as it moves south of Kalispell and into the stable ridge environment. The impact from snow alone will likely not be very high but there is a chance that freezing rain will mix with the snow. Confidence is low at this time for any freezing rain but the potential exists.
617 AM EST MON JAN 11 2016 HIGH PRESSURE WILL BUILD SOUTH OF THE AREA TODAY AND TONIGHT. A DRY COLD FRONT WILL APPROACH FROM THE WEST TUESDAY AND CROSS THE REGION TUESDAY NIGHT.
1024 AM EST MON JAN 11 2016 HIGH PRESSURE WILL HOLD OVER THE DEEP SOUTH TODAY. A REINFORCING COLD FRONT WILL CROSS THE AREA TUESDAY WITH DRY AND COOL CONDITIONS PREVAILING THROUGH THE END OF THE WORK- WEEK. A BROAD UPPER LEVEL TROUGH WILL SWING TOWARDS THE AREA ON TUESDAY. WINDS MAY ONCE AGAIN BECOME GUSTY DURING THE AFTERNOON ON TUESDAY AHEAD OF THE NEXT COLD FRONT.
953 AM EST MON JAN 11 2016 COOL HIGH PRESSURE WILL BUILD IN THROUGH TUESDAY.
Today will be much warmer than yesterday and we have actually begun warming overnight as winds have shifted to the south-southwest and increased. Highs today will range from near 30 in the vicinity of the MO/IA border where cloud cover will persist most of the day to the lower 40s across the southern CWA. A vort max revolving around an upper level trough will provide a reinforcing cold shot tonight as well as the chance for a few light snow showers or flurries across northern Missouri. Canadian high pressure will then build into the region on Tuesday providing a return to cold temperatures with highs in the 20s.
A STRONGER TROF WILL DROP SOUTH AND EAST OVER THE UPPER MIDWEST ACROSS THE GREAT LAKES LATE TONIGHT THROUGH TUESDAY WHICH WILL SEND A REINFORCING SHOT OF COLD AIR SOUTH ACROSS THE MIDWEST AND LOWER PLAINS.
HIGH PRESSURE AT THE SURFACE WILL ALLOW WINDS TO DIMINISH INTO THE 5-10MPH RANGE ACROSS THE AREA.
HIGH PRESSURE HAS SETTLED OVER THE REGION FOR THE COLDEST MORNING OF THE WINTER SO FAR. CLEAR SKIES AND LIGHT WINDS HAVE ALLOWED TEMPS TO DROP TO THE LOWER TEENS ALONG THE KY BORDER WHERE THERE IS A LITTLE SNOW ON THE GROUND TO THE UPPER TEENS TO AROUND 20 ELSEWHERE. HIGH PRESSURE WILL MOVE TO THE GULF COAST TODAY AND SOUTHWEST WINDS WILL DEVELOP. TEMPS WILL MODERATE THOUGH THE COLD START WILL LIMIT THEIR POTENTIAL TO THE LOWER 40S AT MOST THIS AFTERNOON. TEMPS WILL NOT FALL AS MUCH TONIGHT AS A REINFORCING COLD FRONT APPROACHES AND WINDS STAY UP.
FREEZING FOG ACROSS MUCH OF NORTHERN AND EAST-CENTRAL NEVADA THIS MORNING.
HIGH PRESSURE OVER THE SOUTHEASTERN UNITED STATES WILL MOVE QUICKLY TO THE EAST TODAY ALLOWING FOR THE OLD FRONTAL BOUNDARY OVER THE FLORIDA STRAITS TO MOVE BACK NORTH INTO SOUTHERN PORTION OF SOUTH FLORIDA LATE TONIGHT INTO TUESDAY. THE WEATHER TODAY WILL BE DRY BEFORE SHOWERS RETURN TO THE AREA FOR LATE TONIGHT INTO TUESDAY WITH THE HIGHEST POPS OVER THE SOUTHERN AREAS.
High pressure over the southeast United States will keep us dry through this evening. A fair amount of sunshine and temperatures climbing to around or just slightly above the freezing mark should help to take care of some of the icy patches on area roadways. Not A weak clipper will combine with a weak low over the Midwest this evening to become a single, stronger center of low pressure that will cross the Great Lakes tonight and swing a cold front through the Ohio Valley Tuesday morning. A main band of snow, with embedded stronger bands, is then expected to develop coincident with the cold front as it crosses central Kentucky on Tuesday.
751 AM EST MON JAN 11 2016 A DEEP UPPER LEVEL TROUGH WILL PIVOT THROUGH THE NORTHEAST CONUS EARLY THIS WEEK.
LEADING TO THE HIGH POPS/LOW QPF SCENARIO. VERY COLD TEMPERATURES ARE EXPECTED TUESDAY WITH NEARBY PROXIMITY OF THE THERMAL TROF.
HIGH PRESSURE AND VALLEY INVERSIONS WILL RETURN THROUGH THE FIRST HALF OF THE WEEK. RIDGE BUILDING IN OVER REGION TODAY WILL PROVIDE MOSTLY SUNNY SKIES FOR MOST OF THE CWA WITH THE EXCEPTION OF SOME VALLEYS WHERE STRATUS HAS BECOME PREVALENT OVER NIGHT. HAVE IMPROVED THE SKY CONDITION FOR MOST OF THE WEST DESERT AND SOUTHERN AREAS AS THE HIGH CLOUDS SHOULD BE RATHER THIN SO MOSTLY SUNNY SEEMED MORE APPROPRIATE THEN PARTLY CLOUDY.
THAT RIDGE WILL STAY PARKED OVER THE SOUTH THROUGH THE DAY TODAY AND KEEP TEMPS COOL ONCE AGAIN. MODERATING TEMPS WILL CONTINUE DURING THE DAY ON TUESDAY OUT AHEAD OF A QUICK SHOT OF COOLER AIR EXPECTED BEHIND A DRY COLD FRONT.
AN UPPER-LEVEL RIDGE WILL BUILD ACROSS THE CWA ON WED. WE COULD NEED TO TREND EVEN WARMER FOR FORECAST HIGHS DEPENDING ON REMAINING SNOWPACK. WEATHER COULD BE ACTIVE IN THE EXTENDED AS UPPER RIDGE MOVES EAST OF WYOMING.
A COLD FRONT PUSHED THROUGH THE FLORIDA KEYS OVERNIGHT. TEMPERATURES SHOULD STRUGGLE TO BREAK INTO THE LOWER 70S. HIGH PRESSURE WILL BUILD NORTH OF OUR AREA INTO THE MIDDLE OF THIS WEEK. A LOW PRESSURE SYSTEM WILL SLOWLY DEVELOP AS IT MOVES EASTWARD AND ACROSS THE GULF OF MEXICO.
258 AM PST MON JAN 11 2016 HIGH PRESSURE WILL REMAIN ALONG THE WEST COAST INTO TUESDAY.
MAIN COLD FRONT IS WELL SOUTH OF THE STATE, BUT A WEAKER SURFACE BOUNDARY IS CURRENTLY MOVING INTO SOUTH FLORIDA THIS MORNING.
BIGGEST CONCERN OF THE PERIOD WILL BE A ARCTIC COLD FRONT THAT WILL BRING ACCUMULATING SNOW. STARTING OFF THIS MORNING WITH HIGH PRESSURE CONTINUING TO BUILD ACROSS EASTERN KY. THIS HAS ALSO LEAD TO COOLER TEMPS IN THE AREAS THAT HAVE SEEN CLEARING SKIES AND LESSENING WINDS. OVERALL SEEMS LIKE FORECAST HAS REMAINED ON TRACK WITH COOLER START ACROSS THE WESTERN PORTION OF THE CWA. THE REST OF TODAY EXPECT CLEARING SKIES AND COLD TEMPERATURES WITH HIGHS GENERALLY TOPPING OUT IN THE LOW TO MID 30S AND SOME SPOTS STRUGGLING TO GET ABOVE FREEZING. TUESDAY WILL BE THE MOST ACTIVE PERIOD OF THE SHORT TERM DUE TO A FAST MOVING ARCTIC COLD FRONT THAT WILL SWEEP ACROSS THE REGION. THIS UPPER LEVEL SYSTEM WILL AID IN SWEEPING A SURFACE COLD FRONT ACROSS THE REGION TUESDAY FROM NW TO SE.
700 AM EST MON JAN 11 2016 HIGH PRESSURE WILL BUILD INTO THE REGION TODAY AND PERSIST INTO LATE WEEK.
A COLD FRONT ASSOCIATED WITH CLIPPER MOVES ACROSS TUESDAY MORNING AND EXPECT A BETTER BURST OF SNOW FOR THE MORNING RUSH HOUR. LOWERING INVERSIONS AND A DRY AIRMASS WILL ALSO KEEP A LID ON UPSLOPE AMOUNTS FOR THE RIDGES. TOTAL SNOWFALL OUTSIDE THE RIDGES AND I-80 CORRIDOR WILL BE 1-2 INCHES. WITH 3-4 INCHES NORTH OF I-80 AND IN THE HIGHER ELEVATIONS.
335 AM MST MON JAN 11 2016 A RIDGE OF HIGH PRESSURE WILL BUILD OVER THE SOUTHWESTERN UNITED STATES TODAY. AREAS OF PATCHY FOG AND LOW STRATUS OVER UINTA BASIN AND THE LOWER ELEVATIONS OF SOUTHWEST COLORADO WILL DIMINISH BY LATE MORNING. HIGH TEMPERATURES WILL BE SLIGHTLY WARMER OVER THE HIGHER TERRAIN AS THE RIDGE BUILDS TO OUR WEST.
It will be chilly with highs near 50 for northernmost locations and highs in the lower to mid 50s elsewhere.
COOLER THAN NORMAL THROUGH MIDWEEK THEN MODERATING TEMPS WITH. SKIES SHOULD WILL BE MOSTLY SUNNY WITH HIGHS IN THE UPPER 50S FROM NRN LAKE TO VOLUSIA COUNTY AND IN THE LOW-MID 60S CENTRAL AREAS TO UPPER 60S ACROSS MARTIN COUNTY. THE CENTER OF HIGH PRESSURE WILL REMAIN NORTH OF ECFL AND EVEN THOUGH NORTHWEST WINDS WILL BECOME LIGHT.
AS DRIER AIR WORKS IN WITH BUILDING HIGH PRESSURE. AS HIGH PRESSURE BUILDS OVERHEAD WINDS AND SEAS WILL CONTINUE TO DECREASE TODAY.
WARM FRONT IS SET UP ACROSS WESTERN SD THIS MORNING WITH SHARP TEMPERATURE CONTRAST NOTED IN OBS. LOW PRESSURE ALONG WITH WARM/COLD FRONT WILL ALL TRACK EAST- SOUTHEAST ACROSS THE AREA TODAY. HAVE DECREASED HIGHS OVER THE NORTHEAST CWA WHERE WARMER AIR NEVER MAKES IT. BEHIND THE COLD FRONT. TEMPS/WIND CHILLS WILL END UP BEING WARMER THAN FORECAST.
833 AM CST MON JAN 11 2016 HAVE UPDATED TO INCLUDE FREEZING FOG ADVISORY FOR MUCH OF THE TEXAS PANHANDLE THROUGH 11 AM TODAY. /ISSUED 510 AM CST MON JAN 11 2016/ PATCHY FREEZING FOG WILL CAUSE FORECAST CONFIDENCE TO BE LOW FOR THE START OF THE 12Z TAF CYCLE. KAMA IS THE ONLY TERMINAL BEING IMPACTED BY THE FREEZING FOG BUT THE FOG IS IN THE VICINITY OF KDHT. HOWEVER WEAK MOIST AIR ADVECTION ABOARD SOUTH/SOUTHWEST WINDS AHEAD OF THE TROUGH AXIS CONTINUES TO MAINTAIN SOME STRATUS AND PATCHY FREEZING FOG ACROSS THE REMAINDER OF THE PANHANDLES.
