EXPECT VFR CONDITIONS TO PREVAIL THE REST OF THE EVENING THROUGH EARLY SAT MORNING ACROSS THE RIO GRANDE VALLEY AND THE NORTHERN RANCHLANDS AS 500MB RIDGE ACROSS TEXAS CONTINUES TO PROVIDE SUBSIDENCE ACROSS THE AREA. UPPER LEVEL RIDGE CENTERED OVER THE TEXAS PANHANDLE REMAINS THE DOMINANT FEATURE THROUGH THE PERIOD. 850 MB TEMPERATURES WILL BE A DEGREE OR TWO WARMER TOMORROW AND APPROACH 25C ACROSS ZAPATA CONTINUING THE HOT TEMPERATURES.
THIS WILL HELP PUSH A SURFACE FRONT SOUTHWARD INTO CENTRAL KANSAS BY THIS AFTERNOON WITH A TROUGH OF LOW PRESSURE ACROSS THE KS/CO BORDER.
OTHERWISE THE CENTER OF THE UPPER HIGH WAS OVER TX WHILE AN OLD SFC BOUNDARY WAS ACROSS CENTRAL AL.
SATELLITE IMAGERY AND UPSTREAM OBSERVATIONS INDICATE THAT THE CLOUD SHIELD AROUND THIS CYCLONE IS MORE EXPANSIVE THAN DETERMINISTIC MODEL GUIDANCE IS PICKING UP ON. TEMPERATURES WILL LIKELY FALL INTO THE MID 20S OR SO GIVEN THAT CURRENT TEMPERATURES ARE GENERALLY ONLY IN THE LOWER 30S AND FALLING.
WINDS WILL DIMINISH OVERNIGHT AS THE COLD FRONT PASSES THROUGH.
LOW PRESSURE CURRENTLY RESIDES OVER EASTERN MINNESOTA WITH HIGH PRESSURE OVER NORTHERN MONTANA.
COLD FRONT REMAINS TO OUR WEST. WIDESPREAD RAIN WILL CONTINUE AHEAD OF THE COLD FRONT AS MOISTURE ADVECTS NORTHWARD AND OVER THE STATIONARY FRONT TO OUR SOUTH. THE RAIN WILL END FROM WEST TO EAST THURSDAY MORNING WITH SOME DRIZZLE POSSIBLE WITH THE LOW CIGS. WINDS WILL BECOME SOUTHERLY OVERNIGHT AND THEN SHIFT TO THE NORTHWEST BEHIND THE COLD FRONTAL PASSAGE THURSDAY MORNING.
LOW PRESSURE NEAR THE NRN GULF COAST WILL LIFT N/NE ALONG A SOMEWHAT DISJOINTED COLD FRONT MOVING INTO THE EASTERN CONUS. THIS WILL ALLOW STALLED BOUNDARY NEAR FL/GA LINE TO LIFT NORTHWARD AS A WARM FRONT INTO TONIGHT.
VFR CONDITIONS CURRENTLY HOWEVER THERE IS SOME POTENTIAL FOR LOW CLOUDS TO AFFECT ALL THREE SITES AFTER THE COLD FRONT COMES THROUGH WHICH COULD DROP CIGS INTO MVFR. KGUY HAS THE HIGHEST LIKELIHOOD FOR REACHING MVFR AS SNOW SEEMS LIKELY BETWEEN 16 AND 18Z. A BROAD TROUGH OF LOW PRESSURE ALOFT IS SLIDING EAST OF THE PANHANDLES TODAY.
A COUPLE OF DIFFERENT AREAS OF SHOWERS (SOME OF THEM HEAVY) HAVE DEVELOPED ALONG AN AXIS OF VORTICITY OVER NW AL AHEAD OF THE PRIMARY SFC COLD FRONT LOCATED OVER THE MS RIVER. ALSO MADE SOME SLIGHT ADJUSTMENTS TO THE TEMPERATURE, SFC WIND, AND DEWPOINT FORECAST GIVEN THE CURRENT OBS AND PROGRESSION OF THE SFC COLD FRONT. IN REGARDS TO THAT COLD FRONT, IT APPEARS THAT FROPA WILL BE AROUND MIDNIGHT OVER NW AL, I-65 CORRIDOR BY 4AM, AND NE AL/FRANKLIN TN BY 6 AM.
AS THE COLD FRONT THAT MOVED THROUGH THE REGION EARLY THIS MORNING CONTINUES TO MOVE FURTHER EAST OFFSHORE OF THE TX COASTLINE. 500 MB AND SURFACE RIDGING WILL DOMINATE THE RGV THROUGHOUT THE SHORT TERM PERIOD MAINTAINING A STEADY FLOW OF COOLER AND DRIER AIR OVER THE REGION THROUGH TOMORROW NIGHT. LOWS TOMORROW NIGHT WILL BE DRIVEN BY RADIATIONAL EFFECTS AS THE LOW LEVEL FLOW WILL BE WEAKENING. DUE TO THE GENERAL WEAKNESS OF THE CAA IN THE WAKE OF THIS MORNINGS FRONT DO NOT BELIEVE THAT WIDESPREAD FREEZING TEMPERATURES WILL BE A BIG THREAT TONIGHT OR TOMORROW NIGHT. HOWEVER AN ISOLD NEAR FREEZING REPORT CANNOT BE RULED OUT ESPECIALLY IN SOME OF THE RANCHLAND AREAS ACROSS THE NORTHERN TIER OF COUNTIES.
OTHERWISE BUILDING SFC RIDGING INFLUENCES SHOULD RESULT IN DRY CONDITIONS WITH RATHER QUICK LOW LEVEL CEILING EROSIONS CKV/BNA.
952 PM EST WED DEC 16 2015 A PASSING FRONTAL SYSTEM WILL BRING RAIN OVERNIGHT AND COLD FRONT WILL BRING RAIN LATE TONIGHT THROUGH THURSDAY FOLLOWED BY MUCH COLDER TEMPERATURES INTO THE WEEKEND.

514 PM CST WED DEC 16 2015 AN AREA OF LOW PRESSURE.
527 PM CST WED DEC 16 2015 Cold front was pushing across the forecast area this afternoon, accompanied by a brief period of wind gusts 30-40 mph. Temperatures reached the mid 50s in many areas ahead of the front, but had already fallen back down into the lower 40s west of the Illinois River. Large cloud shield associated with a low pressure just north of Minneapolis extended as far south as northern Missouri, with the leading edge starting to move into the far western parts of the forecast area. The low cloud deck is not expected to make a lot of southern progress, as the low itself pulls northeast, so have kept skies partly cloudy overnight across southeast Illinois.
Temperatures are forecast to fall into the 20s for the most part, with some low-lying areas and river valleys likely dipping into the lower 20s by sunrise. The trough axis to our west will cross the area by midday Thursday. This will push a Pacific cold front across West Central TX tomorrow, mainly during the morning hours. Expect highs ranging from the mid 50s across the Big Country to the lower 60s across the northwest Hill Country.
WINTER STORM SYSTEM WINDING DOWN WITH DEF ZONE PRECIP FINALLY BEGINNING TO MOVE EAST AS THE UPPER LOW IS SHIFTING INTO ONTARIO. WITH THE UPPER LOW MOVING EAST NORTHWESTERLY FLOW FROM CANADA WILL ALLOW COLDER AIR TO BEGIN TO FILTER INTO THE REGION DURING THE DAY THURSDAY CAUSING EITHER STEADY OR EVEN FALLING TEMPS DURING THE DAYTIME HOURS.
THEN TRENDING COOLER AGAIN BY LATE THURSDAY. A MOSTLY CHANNELED DISTURBANCE WILL SWING FROM HELLS CANYON SOUTHEAST ACROSS THE TEXAS PANHANDLE MIDDAY THURSDAY WHILE AT THE SURFACE A TROUGH WILL GRADUALLY MATURE AND RELEASE EAST ACROSS THE AREA LATER TONIGHT AND THURSDAY. OFF THE CAPROCK A COOL RIDGE WILL HOLD AT LEAST THIS EVENING BEFORE NUDGING EAST.
931 PM CST WED DEC 16 2015 PRE FRONTAL TROUGH NOW OVER THE PLATEAU WITH THE MAIN BOUNDARY NOW PUSHING INTO WESTERN MIDDLE TN. OTHERWISE BUILDING SFC RIDGING INFLUENCES SHOULD RESULT IN DRY CONDITIONS WITH RATHER QUICK LOW LEVEL CEILING EROSIONS CKV/BNA.
/ISSUED 240 PM CST WED DEC 16 2015/ Much more late fall to winter like conditions across the region today in the wake of last night's cold frontal passage. High temperatures running very close to seasonal normals, although the breezy west to northwesterly winds are making it feel quite a bit cooler than that. Conditions tomorrow will be a bit cooler, resulting from an increase in cloud cover associated with a fast moving, but strong upper wave that will move through Kansas and into Oklahoma during the afternoon and evening.
534 PM CST WED DEC 16 2015 VFR CONDITIONS WILL PREVAIL THROUGH THE NEXT 24 HOURS ACROSS OUR TERMINAL LOCATIONS IN THE WAKE OF A COLD FRONT WHICH MOVED THROUGH OUR REGION EARLIER TODAY. /ISSUED 238 PM CST WED DEC 16 2015/ COLD FRONT HAS MOVED ACROSS MOST OF THE AREA. WITH TEMPS FALLING INTO THE LOWER TO MID 30S AREAWIDE WITH PATCHY FROST POSSIBLE.

518 PM CST WED DEC 16 2015 UPDATED AVIATION PORTION FOR 00Z TAF ISSUANCE COOLER AND DRIER WEATHER FOR A COUPLE DAYS.
STILL EXPECT THE HIGHEST ACCUMULATIONS IN FOOTHILLS LOCATIONS SUCH AS RED LODGE. WARMER CONDITIONS CAN BE EXPECTED OUT EAST WITH CLOUD COVER OVER MILES CITY. UPPER LEVEL RIDGE MOVES IN THURSDAY AND INCREASING PRESSURES OVER THE YELLOWSTONE PARK WILL ELEVATE GAP WINDS THROUGH LIVINGSTON AND BIG TIMBER. THIS RIDGE MOVES EAST THURSDAY NIGHT ALLOWING GOOD RADIATIVE COOLING CONDITIONS IN MILES CITY.
At the surface, a low pressure system was moving through the northern MO river valley with a training cold front extending south through the lower MO river valley. Relatively weak high pressure was noted over the Rockies and adjoining high plains. A dry airmass had moved in behind the cold front with dewpoints across the region in the teens and lower 20s. With the stratocu field likely falling apart with sunset, think conditions for radiational cooling will be in place long enough for low to drop into the lower and mid 20s tonight.
521 PM CST WED DEC 16 2015 FOR 00Z TAFS /ISSUED 222 PM CST WED DEC 16 2015/ THE 20Z SURFACE ANALYSIS INDICATED THAT THE COLD FRONT HAD NOW MOVED EAST TO ALONG THE MISSISSIPPI RIVER AND BARELY INTO NORTHWEST MISSISSIPPI. ALONG A PRE-FRONTAL TROUGH TOWARD THE FORECAST AREA.
