BUT IT WILL BE NOTICEABLY WARMER THAN LAST NIGHT. EXPECT LOWS TO REMAIN ABOVE FREEZING ACROSS MOST OF THE MIDSOUTH WITH THE EXCEPTION OF LOCATIONS NEAR THE TENNESSEE RIVER AND ALABAMA STATE LINE. TEMPERATURES WILL CONTINUE TO TREND WARMER AND REMAIN DRY THROUGH THANKSGIVING.
THE LOW CLOUDS ON SATL CONT TO MARCH SEWD FROM THE NRN PLAINS INTO THE NRN HALF OF WI ON A W-NW FLOW ALOFT. IT WOULD APPEAR THAT MOSTLY CLDY SKIES WOULD PREVAIL ACROSS THE NORTH WITH SKIES BECOMING MOSTLY CLOUDY SOUTH AS SOME OF THE LOW CLOUDS SAG SOUTH AND THE HI/MID CLOUDS ARRIVE. TUESDAY NIGHT THROUGH MONDAY THE NWP MODELS ARE STILL IN FAIRLY GOOD AGREEMENT REGARDING THE PROGRESSION OF A SLOW MOVING LOW PRESSURE SYSTEM TRACKING THROUGH THE WESTERN GREAT LAKES DURING THE MIDDLE TO LATE PART OF THE WEEK.

10 AM READINGS WERE MAINLY IN THE LOWER AND MIDDLE 60S. SOUTHERLY WINDS PICK UP TODAY IN ADVANCE OF A COLD FRONT, AND BY THIS AFTERNOON EXPECT WINDS OVER AT LEAST THE WESTERN HALF OF THE AREA TO BE BLOWING STEADY AT 10 TO 15 MPH, WITH SOME GUSTS AROUND 25 MPH.
A DEEP AREA OF LOW PRESSURE WAS LOCATED OVER THE CENTRAL PLAINS. A WELL DEFINED TROUGH AXIS EXTENDS SOUTH OF THE LOW INTO CENTRAL TEXAS. A COLD FRONT TRAILS WELL BEHIND THE TROUGH AXIS ACROSS THE TEXAS PANHANDLE. THE TROUGH AXIS WILL BE THE CATALYST FOR SHRA/TSRA ACTIVITY THIS EVENING AS IT MOVES ACROSS SE TX. THE COOLER AIR WILL LAG A BIT UNTIL THE ACTUAL FRONT ARRIVES LATE TONIGHT. SO LEANED TOWARD THE WARMER SIDE OF GUIDANCE FOR MIN TEMPS.
FREEZING TEMPERATURES ARE EXPECTED EAST AND SOUTH OF TUCSON THURSDAY MORNING. WARMER DAYTIME TEMPERATURES WILL RETURN STARTING THURSDAY.
MVFR CIGS WEST OF THE REGION WILL GRADUALLY EXPAND OVER THE AREA AFTER 23Z AS A COLD FRONT APPROACHES FROM THE WEST.

A COLD FRONT WITH A FEW SHOWERS AND THUNDERSTORMS WILL ADVANCE RAPIDLY ACROSS THE NORTHWEST GULF THURSDAY.
SKIES RANGE FROM PARTLY TO MOSTLY CLOUDY ON THE WESTERN PORTION OF THE LOWER KEYS AND MOSTLY SUNNY ELSEWHERE. LOCAL RADARS ARE DETECTING A FEW SHOWERS JUST OFF THE WESTERN TIP OF THE LOWER KEYS. A SPRAWLING RIDGE OF HIGH PRESSURE IS CENTERED OVER THE FLORIDA PENINSULA AND THE ADJACENT ATLANTIC AND GULF WATERS. WITH THE CLOSE PROXIMITY OF THE RIDGE.
An upper level low will move out of Colorado and along the KS/NE today. This will help push a strong cold front through western Kansas. A wide range of temperatures are expected today with highs ranging from the lower 40s across northwest and west central Kansas to around 60 degrees across south central Kansas.
East to west oriented snow bands will continue to produce moderate to heavy snow in localized areas this afternoon and evening as a low pressure system moves over the Northern Rockies. A weak ridge will lead to a mostly cloudy but quiet day Thursday.
353 PM CST WED NOV 11 2015 (Tonight and Thursday) A Pacific cold front has moved through all but extreme southeast counties as of mid afternoon. A rather extensive but thin cirrus shield will advect northeast across the southeastern half of the forecast area overnight and should keep temperatures from falling below the lower 40s.
COOLER TEMPERATURES IN THE MIDLEVELS ARE EXPECTED WHICH WILL WEAKEN THE CAP ALLOWING FOR A BIT MORE ISO/SCT SHRA/TSRA DEVELOPMENT LATE TONIGHT. AN EARLY WIND SHIFT OUT OF THE NORTH IS EXPECTED AT LRD BY LATE AFTN DUE TO A PREFRONTAL TROUGH.
UPPER AIR ANALYSIS THIS MORNING SHOWED A DEEP TROUGH EXTENDING FROM EASTERN COLORADO TO NORTHWESTERN MEXICO MAKING THE FLOW SOUTHWESTERLY ACROSS TEXAS. THE COLD FRONT IS MOVING THROUGH AND CURRENTLY STRETCHES FROM DALLAS TO DEL RIO. THE UPPER TROUGH WILL MOVE OFF TO THE NORTHEAST AND THE FLOW WILL BECOME MAINLY ZONAL. THEN COOLER. TEMPERATURES WILL BE MUCH COOLER THURSDAY.
The long advertised arrival of a vigorous upper trough and potential severe weather generator has been lifting east-northeast over the past 24 hours and looks like it has begun to accelerate and turn more northeast. While scattered weak elevated convection driven by warm air advection will be possible this morning the main show/concern will be along an eastward advancing cold front/dryline. While the entire CWA will have a threat of severe weather this afternoon the highest risk areas will be over north central and northeast MO. In addition, strong and gusty southerly winds will likely achieve advisory criteria by late morning over southern sections of the CWA and as the dryline/cold front surges east through the region the winds will veer to the southwest and ramp up even more with gusts in the 40-50 mph range.
TIGHT PRES GRADIENT ON THE BACK SIDE OF THE LOW WILL SLOWLY DIMINISH. THE LOW WILL BE DEEPENING AS IT TRACKS NEWD AND WE SHOULD SEE SOME MOMENTUM TRANSFER DOWNWARD.
TO THE LOW 50S IN THE WEST WHERE SOUTHERLY WINDS HAVE DEVELOPED.

A BIT OF FOG AND DRIZZLE WILL LINGER THIS AFTERNOON CENTRAL BUT TEMPERATURES ARE ABOVE FREEZING SOT NO FREEZING DRIZZLE PROBLEMS AT THIS JUNCTURE. TONIGHT WILL SEE A COLD FRONT ENTER THE NORTHWEST BY MIDNIGHT AND SWEEP THROUGH THE REGION BY SUNRISE THURSDAY. MODELS NOW AGREE MUCH BETTER ON THE LOW LEVEL WINDS WITH THE GFS DECREASING THE H850 WINDS A GOOD 15 TO 20 KTS OVER PREVIOUS RUNS. WITH TEMPERATURES ABOVE FREEZING MAY GET A BIT OF BLOWING SNOW THURSDAY AT PLACES LINE RUGBY BUT NOT THAT MUCH OVERALL.
247 PM CST WED NOV 11 2015 Strong westerly winds continue to plague much of the region as an upper trough quickly swings into the Central Plains, pushing a Pacific front east through the CWA throughout this morning. As of 2pm CST, winds were beginning to decrease as the upper speed max associated with the ua trough shifts to the NE. Cooler air will filter into the area tonight and with light winds and clear skies expected, low temperatures look to range from the low 30s across the NW to the upper 30s/low 40s SE by early Thursday morning.
155 PM PST WED NOV 11 2015 HIGH PRESSURE BUILDING INTO THE GREAT BASIN WILL BRING VERY DRY CONDITIONS AND GUSTY SANTA ANA WINDS TO THE REGION INTO THE WEEKEND.

308 PM CST WED NOV 11 2015 20Z water vapor shows a closed upper low lifting across southeast NEB. For tonight, the forecast is for the strong cyclone to continue moving northeast with dry air and large scale subsidence continuing to overspread the forecast area. Have expanded the high wind warning to include the entire forecast area until 6 pm. Think the low clouds that are wrapping around the back side of the low will be temporary as dry air advection ultimately win out with skies clearing out overnight.
/ISSUED 953 AM CST WED NOV 11 2015/ SHOWERS BEGINNING TO INCREASE IN COVERAGE ACROSS THE REGION THIS MORNING AS AN UPPER-LEVEL TROUGH MOVES EAST ACROSS THE MIDWEST.
A FAST MOVING SHORT WAVE TROUGH WILL PASS THROUGH THE ID PANHANDLE INTO WESTERN MT TODAY. ANY SHOWER DEVELOPMENT IN THE LOWER SNAKE PLAIN WILL TRACK CLOSE TO THE NORTHERN FOOTHILLS.
The low will continue to deepen as these features track northeast. This system will drag a cold front through the region early Thursday morning. However, as the low level jet strengthens late this evening, winds around 2000 feet will increase to 45 knots or so.
BELIEVE THAT BY SUNRISE MOST IF NOT ALL THE AREA WILL BE OVERCAST WITH THIS LOWER CLOUD DECK AND FOG WILL THUS NOT BE A CONCERN. LOOKING AT HIGHS GENERALLY IN THE LOW 80S AREA-WIDE DESPITE CONSIDERABLE CLOUDINESS. FEATURE WILL DRAG A COLD FRONT ACROSS THE FORECAST AREA PRIMARILY OVERNIGHT. A COLD FRONT WITH A FEW SHOWERS AND THUNDERSTORMS WILL ADVANCE RAPIDLY ACROSS THE NORTHWEST GULF THURSDAY.
