AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MEMPHIS TN 341 PM CDT FRI AUG 15 2008 .DISCUSSION... SHOWERS AND THUNDERSTORMS HAVE REALLY INCREASED ACROSS THE MIDSOUTH THIS AFTERNOON AS AN UPPER LEVEL SHORTWAVE MOVES ACROSS THE AREA. SO FAR TODAY...STORMS HAVE BEEN RATHER TAME WITH ONLY HEAVY RAINFALL REALLY TO REPORT. THERE STILL EXISTS SOME THREAT FOR LOCALIZED HEAVY RAINFALL AND A FEW STRONG THUNDERSTORMS SO WILL KEEP MENTION IN THE HWO THROUGH THE EVENING HOURS. CONVECTION SHOULD PERSIST THROUGH MUCH OF THE EVENING AND OVERNIGHT HOURS ESPECIALLY ACROSS AREAS SOUTH OF INTERSTATE 40 SO HAVE RAISED POPS FOR TONIGHT IN THESE AREAS. HIGH PRESSURE SEEMS A LOT SLOWER BUILDING IN ACROSS THE AREA ON SATURDAY SO HAVE RAISED PRECIPITATION CHANCES FOR EASTERN ARKANSAS...NORTH MISSISSIPPI...AND SOUTHWEST TENNESSEE. THINK SKIES MAY CLEAR ACROSS EXTREME NORTHERN AREAS OF THE MIDSOUTH BY SATURDAY AFTERNOON SO THE WARMEST TEMPERATURES WILL BE ACROSS THESE AREAS NORTH OF INTERSTATE 40. BY SATURDAY NIGHT...RAIN WILL HAVE SHIFTED SOUTH OF THE AREA AS HIGH PRESSURE BEGINS TO BUILD KEEPING DRY CONDITIONS OVER THE AREA. MEDIUM RANGE MODELS BEGIN TO DIVERGE IN SOLUTIONS BEGINNING MONDAY AS THEY ARE HAVING A HARD TIME DETERMINING WHAT THE UPPER LOW OVER THE CENTRAL PLAINS AND THE TROPICAL SYSTEM OVER THE SOUTHEAST U.S. ARE GOING TO DO. AS A RESULT...THE MODELS ARE HAVING A DIFFICULT TIME RESOLVING EXACTLY WHAT WILL HAPPEN OVER THE MIDSOUTH DURING THIS TIME FRAME AS THE AREA LOOKS TO BE SQUEEZED BETWEEN THESE TWO SYSTEMS. WITH THAT SAID...MONDAY AND TUESDAY WILL REMAIN DRY WITH HIGH PRESSURE OVER THE AREA. HIGH TEMPERATURES WILL BE NEAR NORMAL OR SLIGHTLY ABOVE NORMAL. BY WEDNESDAY...WITH THE SURFACE HIGH SHIFTED EAST OF THE AREA... SOUTHERLY FLOW WILL RETURN ALLOWING GULF MOISTURE TO MOVE BACK INTO THE AREA. AS A RESULT...THINK THE CHANCES FOR AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS WILL INCREASE WEDNESDAY AND THURSDAY. HOWEVER...HIGH TEMPERATURES WILL REMAIN NEAR SEASONAL VALUES WITH HIGHS IN THE LOWER 90S. && .PRELIMINARY POINT TEMPS/POPS...
