-- Changed Discussion --
SHOWERS AND A FEW STORMS NOW DEVELOPING ON THE PLATEAU...EXTENDING TO THE NORTHEAST INTO THE WNW-ESE BAND ACROSS KY AND SW VA. UPPER FLOW IS STEERING THIS CONVECTION ALONG THE AXIS OF THE PLATEAU...SO IT WILL BE SLOW TO COME OUT INTO THE VALLEY. LATER TONIGHT THE MAIN BAND OF PRECIP WILL MOVE INTO THE AREA...AND THE FLOW WILL ALSO VEER...GIVING A BETTER EASTWARD PUSH TO THE CONVECTION. TSRA WILL LIKELY BE HEAVY ENOUGH TO REDUCE VSBY AT LEAST TO MVFR AND POSSIBLY IFR. ALSO...EXPECTING SOME FOG TO DEVELOP IN THE WAKE OF THE STORMS. ALTHOUGH VSBY WILL IMPROVE AS THE HEAVIER RAINS MOVE AWAY...OVER THE NEXT COUPLE OF HOURS AFTERWARD...ALLOWING FOR SOME RADIATIONAL COOLING OF THE WET GROUND WILL LIKELY GET VSBY BACK DOWN TO MVFR OR IFR...UNTIL AFTER DAILY MIXING STARTS. MAIN LIMIT TO FOG FORMATION IS IF GRADIENT WINDS STAY TOO HIGH...MOST LIKELY AT KTYS.
