-- Changed Discussion --
(TODAY AND TONIGHT)...SURFACE HIGH PRESSURE WILL EXTEND INTO OUR AREA AS IT DRIFTS BY TO OUR NORTH...AND AN UPPER RIDGE WILL BUILD ACROSS THE REGION. WILL SEE SOME CLOUDS TO START ESPECIALLY NORTH...BUT THESE SHOULD DECREASE FROM SOUTHWEST TO NORTHEAST DURING THE DAY AND EXPECT MAINLY CLEAR CONDITIONS TONIGHT. WILL ADJUST SOME MAV MAX TEMPS UP A BIT FOR TODAY...BUT OVERALL WILL NOT STRAY FAR. .LONG TERM...(SUNDAY THROUGH FRIDAY)...THE PERIOD STARTS OUT WITH AN UPPER LEVEL RIDGE AND DRY AIR IN PLACE ON SUNDAY. THE RIDGE STARTS TO FLATTEN OUT MONDAY INTO TUESDAY WITH A LOW LEVEL SOUTHERLY FLOW DEVELOPING ACROSS THE SOUTHEASTERN UNITED STATES. MOST OF THE FORECAST AREA SHOULD REMAIN DRY ON MONDAY. HOWEVER...LOW LEVEL MOISTURE AND DECREASING STABILITY WILL LEAD TO WIDELY SCATTERED SHOWERS AND A COUPLE THUNDERSTORMS...MAINLY ACROSS THE NORTHERN PORTION OF THE FORECAST AREA ON TUESDAY AND WEDNESDAY AS A WEAK SHORT WAVE TRAVERSES THE NORTHEASTERN STATES WHILE DRAGGING A BACK DOOR FRONTAL BOUNDARY INTO THE SOUTHERN APPALACHIAN REGION. THERE WILL BE A BETTER CHANCE FOR SHOWERS AND THUNDERSTORMS ACROSS THE ENTIRE FORECAST AREA ON THURSDAY AS STRONGER UPPER LEVEL WAVE PULLS ANOTHER COOL FRONT INTO THE SOUTHERN APPALACHIANS. KEPT CHANCE POPS FOR CONVECTION GOING ON FRIDAY WITH THE BOUNDARY STILL IN THE VICINITY. MORE ABOVE NORMAL WARMTH IS EXPECTED THROUGH THE LONG TERM WITH HIGHS IN THE UPPER 70S AND 80S ALONG WITH LOWS IN THE 50S TO LOWER 60S.
