LOSS OF BOUNDARY LAYER HEATING HAS STABILIZED THE LOWER TROPOSPHERE
OVER THE LAST HOUR.  THIS PROCESS WILL CONTINUE WITH ADDITIONAL
COOLING AND UPDRAFT INTENSITY SHOULD GRADUALLY WANE THROUGH MID
EVENING.  EVEN SO...IT APPEARS STRONG FRONTAL CONVERGENCE AND LARGE
SCALE ASCENT WILL BE MORE THAN ADEQUATE FOR CONTINUED THUNDERSTORM

ACROSS THE OH VALLEY/CNTRL APPALACHIANS.  SHEAR PROFILES SUPPORT
