AIR MASS SOMEWHAT CAPPED WITH SHEAR FAIRLY WEAK. DO NOT EXPECT THESE STORMS TO HOLD TOGETHER VERY LONG INTO FA BUT CONSEQUENCE WILL BE LEFT OVER OUTFLOW BOUNDARY. THIS MIGHT BE FOCUS NEEDED TO BUILD TSTMS LATER. SHORT WAVE TROUGH INCHING TOWARD FA ACROSS TN AND SHOULD MAKE IMPACT KNOWN LATER THIS EVENING. BEST LOW LEVEL MOISTURE ARRIVES AFTER 00Z WHEN LOW LEVEL FLOW BACKS FROM ESSENTIALLY A DRY WSW FLOW TO MORE SW TO S FLOW. COOLER MID LEVEL TEMPERATURES AND STEEPENING LAPSE RATES BY 03-06Z TIME FRAME SHOULD BE SUFFICIENT TO EITHER SUSTAIN LINE OF CONVECTION FROM AL/GA OR TO ASSIST ANY STORMS THAT DEVELOP IN AREA. POTENTIAL FOR SEVERE INCREASES BUT BELIEVE THAT WITH LOSS OF HEATING... POTENTIAL REMAINS MARGINAL FOR MOST OF AREA. PRIME AREAS WILL BE NORTHERN ZONES WHERE ACTIVITY ASSOCIATED WITH BOUNDARY ACROSS VA MIGHT SLIP DOWN AND SOUTHERN ZONES WHERE GA ACTIVITY WILL CERTAINLY BE A FACTOR.
