AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 410 AM CDT SUN MAR 31 2013 .DISCUSSION... ACTIVE WEATHER PATTERN TO CONTINUE THROUGH MID WEEK. FOR TODAY... A STRONG SHORT WAVE IN NORTHWEST FLOW ALOFT WAS BEARING DOWN ON WESTERN OKLAHOMA AND NORTHWEST TEXAS. SHOWERS AND STRONG THUNDERSTORMS WILL CONTINUE TO DEVELOP AHEAD OF HIS FEATURE AS IT DIVES SOUTHEAST THIS MORNING AND SHOULD REACH THE NORTHWEST PORTION OF THE CWA BY MID MORNING. COULD SEE SEVERE STORMS DEVELOP OVER EAST TEXAS INTO NORTH LOUISIANA AS TEMPERATURES INCREASE BY LATE MORNING AND MLCAPE VALUES EXCEED 1000 J/KG. THE SYSTEM SHOULD BE EAST OF THE CWA AROUND 00Z THIS EVENING. A COLD FRONT WILL FOLLOW THIS SYSTEM...HOWEVER...WITH MOSTLY ZONAL FLOW ALOFT...THE FRONT LOOKS LIKE IT WILL STALL...POSSIBLY NEAR INTERSTATE 20. WITH DRY AIR FILTERING INTO THE AREA FOLLOWING THE SHORT WAVE... THE CHANCE OF ADDITIONAL PRECIPITATION LOOKS SMALL THROUGH MONDAY NIGHT. ON TUESDAY A SHIFT IN UPPER PATTERN TO A MORE SOUTHWEST FLOW WILL ALLOW MOISTURE TO SPREAD BACK INTO THE REGION...OVERRIDING COOLER SURFACE AIR...SETTING UP AN ISENTROPIC RAIN EVENT. EXPECT PERIODS OF RAIN TO BEGIN TUESDAY...CONTINUING UNTIL THE UPPER TROUGH SHIFTS EAST OF THE REGION DURING THE DAY THURSDAY. MODELS ARE STILL IN FAIRLY GOOD AGREEMENT WITH THE PROGRESSION OF EVENTS WITH THE ECM SLIGHTLY SLOWER. HOWEVER...WILL STILL GRADUALLY END THE RAIN FROM WEST TO EAST THURSDAY. DRY AIR TO FOLLOW THE TROUGH... WITH A WARM UP EXPECTED TO BEGIN FRIDAY. TEMPERATURES WILL REMAIN FAIRLY MILD UNTIL THE COLD AIR ARRIVES. LOOKS LIKE A TIGHT TEMPERATURE GRADIENT WILL SET UP TUESDAY... NEAR INTERSTATE 20 AND IT WILL BE WEDNESDAY BEFORE ALL OF THE CWA COOLS. HIGHS WILL FALL INTO THE 50S ACROSS MOST OF THE FOUR STATE REGION WEDNESDAY AND THURSDAY BUT SHOULD WARM BACK INTO THE 70S FRIDAY. && .AVIATION... LOW STRATUS IS EXPANDING NORTHWARD AND SHOULD BE AFFECTING MOST OF THE TAF SITES AT THE START OF THE 12Z TAF PERIOD. ANY LOW VSBYS DUE TO FOG SHOULD IMPROVE BY MID MORNING AND CIGS MAY LIFT SLIGHTLY BUT MVFR CONDITIONS ARE EXPECTED TO PREVAIL FOR MUCH OF THE PERIOD. CONVECTION CURRENTLY ONGOING ALONG AND NORTH OF I-40 IN WRN OK AHEAD OF AN APPROACHING COLD FRONT IS EXPECTED TO REACH THE AREA BY THIS AFTERNOON. IN ADDITION...REDEVELOPMENT OF SCT CONVECTION WILL BE POSSIBLE JUST ABOUT ANYWHERE DUE TO LEFT OVER BOUNDARIES FROM TSTMS THAT HAVE ALREADY OCCURRED OVER THE PREVIOUS 24 HOURS. THUS...WIDESPREAD CONVECTION WILL LIKELY IMPACT ALL OF THE TAF SITES AT SOME POINT OVER THE NEXT 24 HOURS. SHWRS/TSTMS SHOULD GRADUALLY END FROM NW TO SE NEAR THE END OF THE TAF PERIOD AS THE COLD FRONT MOVES ACROSS THE AREA. /09/ && .PRELIMINARY POINT TEMPS/POPS...
