POTENTIAL EXISTS FOR A WIDESPREAD SEVERE WEATHER EVENT /MAINLY IN THE FORM OF DAMAGING WIND AND LARGE HAIL/ TO OCCUR OVER A PORTION OF THE OH VALLEY BEGINNING WEDNESDAY AFTERNOON INTO THE EVENING. RICH GULF MOISTURE WITH LOW 70S DEWPOINTS RESIDE OVER THE LOWER MS VALLEY. BROAD ZONE OF SWLY LOW-LEVEL WINDS WILL ADVECT THIS MOISTURE NEWD INTO THE OH VALLEY BENEATH EWD EXPANDING PLUME OF STEEP MID-LEVEL LAPSE RATES. THESE PROCESSES AND DIABATIC WARMING WILL CONTRIBUTE TO A FAIRLY LARGE RESERVOIR OF STRONG INSTABILITY /2500-3000 J/KG MLCAPE/ OVER THE OH VALLEY GENERALLY ALONG AND SOUTH OF THE NWD ADVANCING WARM FRONT.
