/ISSUED 325 AM CDT SUN MAR 27 2016/ ISENTROPIC UPGLIDE CONTINUE TO DEVELOP NORTH OF THE WARM FRONT IN THE COASTAL WATERS THIS MORNING. THIS WILL ALSO BE A QUICK SHOT OF RAINFALL AS THE WINDOW OF OPPORTUNITY CLOSES FAST AS THE COLD FRONT ADVANCES ACROSS THE AREA AND SHOWERS AND THUNDERSTORMS EXPECTED TO EXIT FAIRLY QUICKLY TO THE EAST THIS AFTERNOON.
WITH ONLY A FEW MID-HIGH CLOUDS HOVERING AROUND MOBRIDGE.
GIVEN THE NORTHERLY WIND EARLY THIS EVENING AND WEAK RIDGING MOVING OVER THE AREA. KETCHAM A LEE SIDE LOW PRESSURE AREA ACROSS EASTERN CO LOOKS TO DEEPEN FOR THE DAYTIME TUE. LOW LEVEL MOISTURE TRANSPORT CONTINUES FOR TUE NIGHT WHICH WILL INCREASE THE LOW LEVEL CLOUD COVER ACROSS THE AREA. AS A DRY LINE/COLD FRONT PUSHES EAST ACROSS THE FORECAST AREA WITH INCREASING CONVERGENCE. SO THINK COOLER AIR ALOFT WILL HELP ERODE THE CAP ENOUGH FOR A SCATTERED CONVECTION CHANCE FOR AREAS EAST OF THE KS TURNPIKE FOR WED NIGHT. ANY PRECIP ASSOCIATED WITH THIS SECONDARY COLD FRONT WILL STAY NORTHEAST OF THE FORECAST AREA. WITH RIDGING OVER MOST OF THE PLAINS.

WITH MORNING UPDATE HAD PUT IN SOME ISOLATED SHOWERS AS A PSEUDO WARM FRONT LIFTS ACROSS CWA. ATTENTION TURNS TO NORTHERN STREAM LOW PRESSURE SYSTEM WHICH WILL LIFT THROUGH THE GREAT LAKES TONIGHT. THIS WILL DRIVE A COLD FRONT THROUGH THE CWA LATE TONIGHT/EARLY MONDAY. MUCH LIKE THE LAST DECENT COLD FRONT WE HAD PASS. COLD FRONT WILL BE EXITING THE REGION MONDAY WITH COLD AIR ADVECTION BEHIND IT.
/issued 401 AM CDT SUN MAR 27 2016/ A cold front is moving through the area this morning bringing very windy conditions to the Permian Basin and southeast New Mexico.
TODAY THROUGH MONDAY NIGHT UPPER RIDGE CROSSING THE AREA WILL LEAD TO MOSTLY SUNNY SKIES. MOIST GROUND DUE TO THE RECENT SNOWFALL WILL LIMIT THE POTENTIAL TEMPERATURE RISES TODAY BUT EXPECT MOST AREAS WILL SEE SLIGHTLY WARMER THAN AVERAGE TEMPERATURES. RELATIVELY MILD WEATHER IS EXPECTED AGAIN ON MONDAY WITH INCREASING CLOUDS DURING THE AFTERNOON AHEAD OF AN APPROACHING UPPER TROUGH.
YET TO FOLLOW IS THE COLD FRONT CURRENTLY POISED TO CROSS THE MISSISSIPPI RIVER INTO WESTERN TN/WESTERN MS.
Early this morning an intense upper level trough was lifting northeast across northwest OK. Ahead of the upper trough mid level frontogenesis was occurring across south central and east central KS. Skies will become sunny by noon with afternoon highs in the lower to mid 50s.
THIS EVENING THROUGH MONDAY NIGHT VIGOROUS UPPER TROUGH DIVING SE INTO THE WESTERN CONUS WILL SUPPORT A POTENT WINTER STORM OVER THE REGION BY MID WEEK. DEEP UPPER TROUGH WILL DIG INTO THE WESTERN CONUS.
THE PRE-FRONT HAS MOVES ACROSS THE CWA BUT THE COOLER AIR REMAINS FURTHER NORTH OVER S CENTRAL TEXAS. TEMPERATURES WILL GRADUALLY WARM UP INTO THE LOW 80S ACROSS THE CWA FOR THIS AFTERNOON'S HIGH. AS THE TROUGH TRAVELS EAST. TEMPERATURES WILL BE SLIGHTLY COOLER REACHING THE MID TO UPPER 60S.
STRATUS HAS ALL BUT DISSIPATED WITH THE EXCEPTION BEING ACROSS ORANGE AND ROCKLAND COUNTIES IN THE LOWER HUDSON VALLEY OF NEW YORK. MOSTLY SUNNY SKIES ARE ON TAP FOR THE ENTIRE AREA THIS AFTERNOON WITH SOME HIGH CLOUDS FILTERING IN AHEAD OF A COMPLEX LOW PRESSURE SYSTEM APPROACHING FROM THE SOUTH AND WEST. UPR TROF APPROACHES THE MIDWEST ON THU PRODUCING SW FLOW ALOFT OVER THE NERN CONUS. THE UPR TROF AXIS GETS CLOSER ON FRI WITH SW FLOW ALOFT CONTINUING.
