1242 PM EST SAT MAR 12 2016 A WEAK COLD FRONT WILL CROSS THE AREA THIS AFTERNOON INTO EARLY EVENING. CANADIAN HIGH PRESSURE WILL BUILD TOWARD THE REGION TONIGHT.
A WEAK WARM FRONT STRETCHES FROM NEAR THE AL/GA BORDER TO JUST SOUTH OF THE NASHVILLE AREA AND THEN FURTHER SOUTHWEST INTO NORTHWEST MS/EASTERN ARKANSAS. AN AREA OF LOW PRESSURE OVER EASTERN ARKANSAS IS MOVING NORTHEAST ALONG THIS FRONTAL BOUNDARY. SOME BETTER CONVERGENCE WILL LIKELY DEVELOP AS THIS LOW MOVES NORTHEAST THIS AFTERNOON OVER THE AREA. AS THE ENERGY ASSOCIATED WITH THE UPPER LOW THAT HAS BEEN OVER TEXAS WEAKENS AND MOVES NORTHEAST THROUGH THE AREA.
MEDIUM MID LEVEL RIDGE AXIS EXTENDING FROM THE OH VLY INTO NRN WI LIFTS NORTHEAST WITH MORE OF A SRLY FLOW DEVELOPING AT 500 MILLIBARS. INITIAL VORT LOBE ATTEMPTING TO WORK THROUGH THE RIDGE AXIS ENCOUNTERING WAY TOO MUCH DRY AIR TO BE PRODUCTIVE.
In the upper levels, a trough will move through overnight. At the surface, the low in east Texas will move northeastward towards MO/IL/KY overnight.
COVERAGE WILL GRADUALLY DIMINISH FROM SOUTH TO NORTH THROUGH THE MORNING HOURS ON SUNDAY AS THE STUBBORN UPPER LOW FINALLY EJECTS NORTHEASTWARD TOWARD MEMPHIS AND WEAKENS TO AN OPEN WAVE.

1226 PM EST SAT MAR 12 2016 HIGH PRESSURE CONTROLS THE LOCAL WEATHER INTO EARLY SUNDAY WHEN A WARM FRONT BEGINS TO APPROACH FROM THE SOUTHWEST.
TEMPERATURES WILL BE MODERATED BY THE LOWER/MID 50S DEWPOINTS ACROSS THE AREA. MON-TUE: DEPARTING LOW WILL LEAVE AREA IN FAIRLY DIFFLUENCE ZONAL FLOW WITH DEVELOPING LEE TROUGH. STILL HAVE HINTS OF PRECIPITATION IN CENTRAL KS MON NIGHT AS WEAK COLD FRONT MOVE THROUGH. PRECIPITATION CHANCES BY END OF PERIOD ARE BEING DRIVEN BY ECMWF WHICH IS QUITE AGRESSIVE WITH UPPER LOW LAGGING OVER NORTHERN PLAINS.
1020 AM CST SAT MAR 12 2016 AN UPPER LEVEL LOW CONTINUES TO LIFT ACROSS THE REGION INTO NORTHEAST TEXAS PER WATER VAPOR IMAGERY THIS MORNING. WITH 15Z SURFACE ANALYSIS SHOWING A WEAK SURFACE REFLECTION/TROUGH STRETCHING FROM CENTRAL TEXAS TO NEAR GALVESTON BAY. AS THE UPPER LOW CONTINUES TO MOVE TOWARDS THE ARKLATEX. THIS TROUGH WILL LIFT NORTHEAST WITH IT AND ALLOW FOR WEST/SOUTHWEST SURFACE FLOW TO BECOME ESTABLISHED ACROSS THE REGION THROUGH THE DAY. BUT WITH DAYTIME HEATING AND THE PROXIMITY OF THE UPPER LOW ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL REMAIN POSSIBLE OVER THE EASTERN/NORTHEASTERN COUNTIES FOR MUCH OF THE DAY.
The upper low that has been positioned over Texas the last few days will gradually eject northwards into Arkansas overnight and then up into southeast Missouri and southern Illinois by early Sunday morning. The region will be in between systems briefly Sunday morning so may see a break in precipitation before the second trough nears the region from the southwest. A few residual showers are possible as the low moves eastward, but should end from west to east late Sunday night.
MOSTLY TO LOWER THEM IN THE LOWER SNAKE PLAIN FOR TODAY. THE WEISER BASIN CONTINUES TO BE THE MAIN CONCERN AND A FLOOD WATCH REMAINS IN EFFECT FOR THE LOWER REACH NEAR WEISER. THE NORTH PORTION OF A SPLIT UPPER TROUGH AND ASSOCIATED COLD FRONT WERE LEADING TO THE SCATTERED SHOWERS OVER SW IDAHO EARLY THIS MORNING. THE TROUGH/FRONT WILL BE EAST OF THE AREA BY MIDDAY. A DEEP UPPER LEVEL TROUGH OFF THE PACNW COAST WILL BRING A MOIST SOUTHWEST FLOW INTO THE AREA FOR THE REMAINDER OF THE WEEKEND. SNOW LEVELS WILL LOWER TO BETWEEN 4000 AND 5000 FEET TONIGHT WITH TOTAL SNOWFALL ACCUMULATIONS OF 4 TO 10 INCHES EXPECTED IN THE HIGHER MOUNTAINS. TEMPERATURES WILL BE COOLER.
320 PM CST SAT MAR 12 2016 CURRENT SURFACE ANALYSIS PLACES TROUGH OVER EASTERN MONTANA WITH HIGH OVER THE MIDWEST RESULTING IN GUSTY SOUTHEASTERLY WINDS OVER OUR AREA. UPPER LEVEL ANALYSIS PLACES TROUGH NEAR THE PACIFIC NORTHWEST WITH CUT-OFF LOW OVER THE FOUR CORNERS. RIDGE STRETCHES FROM THE MIDWEST INTO MANITOBA WHILE SOUTHWESTERLY FLOW REMAINS OVER OUR AREA.
MOSTLY TO ACCOUNT FOR SOME LINGERING MOISTURE AND COOLER AIR ALOFT THAT HAS HELPED TO DEVELOP AND SPREAD A 6-7 KFT CLOUD DECK SOUTHWARD. THE CLOUDS HAVE ALSO KEPT TEMPERATURES COOLER SO WE HAVE READJUSTED OUR HOURLIES THROUGH THE AFTERNOON.
UPPER LOW OVER EAST TEXAS AND WESTERN LA WILL CONTINUE TO MOVE NORTHWARD TONIGHT AND ON SUNDAY. AS FOR TEMPS WILL LEAN TOWARDS THE WARMER MOS GUIDANCE THROUGH SUN.

UPPER LEVEL LOW IS CONTINUING TO MOVE NE AND AWAY FROM THE REGION. THE LATEST WATER VAPOR LOOP SHOWS AN UPPER LOW OVER CENTRAL TEXAS EARLY THIS MORNING. GIVEN THE COOLER AIR ALOFT ALONG WITH SOME WEAK SURFACE CONVERGENCE ALONG A REMNANT FRONTAL BOUNDARY. THE ABOVE MENTIONED UPPER LOW WILL TRANSLATE NORTHEAST INTO LOUISIANA BY MID-EVENING. AS THE LOW EXITS. DRY WEATHER IS IN STORE FOR TONIGHT AS ANOTHER UPPER LOW MOVES ACROSS THE TEXAS PANHANDLE. THE UPPER LOW WILL MOVE EAST INTO OKLAHOMA AND A PACIFIC COLD FRONT WILL MOVE INTO SOUTH CENTRAL TEXAS.
354 PM EST SAT MAR 12 2016 ONE MORE INTERNAL UPPER LEVEL JET ENTRANCE REGION TO WORK EASTWARD OUT OF THE OHIO VALLEY LATE THIS AFTERNOON AND EVENING BEFORE THE UPPER LEVEL PATTERN TRANSITIONS IN WHOLE TO A RIDGE-OVER-TROUGH EMBOLISM ACROSS MUCH OF NORTH AMERICA. THIS STRUCTURE IS A BLOCKING PATTERN WHICH WILL RESULT IN SLOWLY EVOLVING WEATHER WITH EFFECTS LINGERING RIGHT THROUGH 84-90 HOURS. STOUT DRY AIR IN THE LOWEST 7000 FT AGL WILL SUPPRESS ANY MEASURING POTENTIAL. THE EASTERN RIDGE AXIS AND EASTERN EDGE OF THE EMBOLISM WILL DRIFT NORTHEAST OF SOUTHEASTERN MICHIGAN AFTER 12Z SUNDAY. BOUGHT IN ON THE COOLER TEMPERATURES SUNDAY DESPITE AN ARGUABLY SLOWER ONSET TIME. COOLER NEAR THE LAKES/RIVERS.

WE SHOULD CONTINUE TO SEE SOME TURBULENT MIXING TONIGHT ACROSS THE AREA SO NOT EXPECTING THE BEST RADIATIONAL COOLING CONDITIONS BUT THINKING THAT EVEN AS THE BOUNDARY LAYER COOLS FOG SHOULD BE ABLE TO DEVELOP AND ONCE IT DOES IT SHOULD HELP TO LOWER TEMPERATURES A BIT MORE SO WE TRENDED TOWARDS THE COOLER STAT GUIDANCE TONIGHT. WIND GUSTS AROUND 25 TO 30 MPH ARE POSSIBLE WITH PEAK HEATING DAYTIME HIGHS ARE EXPECTED TO CLIMB INTO THE LOW-90S WEST AND UPPER-80S EAST.
223 PM MST SAT MAR 12 2016 AFTER MUCH COOLER TEMPERATURES TODAY.
THE LINGERING INFLUENCE OF HIGH PRESSURE WILL ENSURE DRY CONDITIONS WITH JUST SOME HIGH CLOUDS THICKENING AHEAD OF LOW PRESSURE APPROACHING FROM THE SOUTH. THERE WILL ALSO BE WEAK BUT COMPLEX INTERACTIONS LATE TONIGHT AND EARLY SUNDAY BETWEEN THE TENNESSEE VALLEY STATIONARY FRONT BECOMING AND WARM FRONT AND THE COLD FRONT MOVING SOUTHWARD THROUGH THE UPPER MIDWEST AND NORTHERN GREAT LAKES. THESE BOUNDARIES ARE SHOWN TO MEET/MERGE NEAR THE OHIO BORDER RESULTING IN EASTERLY LOW LEVEL FLOW INTO OUR AREA FROM DRY HIGH PRESSURE OVER QUEBEC. THE COMBINATION OF WEAKER MID LEVEL ISENTROPIC ASCENT AND ENHANCEMENT OF DRY EASTERLY FLOW IN THE LOW LEVELS WILL FURTHER REDUCE QPF SUNDAY MORNING.
An upper wave over the Arklatex today will lift northeast toward the lower Ohio Valley tonight, spreading showers and embedded thunder into the region.
