VALID 031424Z - 031530Z

CORRECTED FOR STATE LIST AT TOP

THUNDERSTORMS ARE BEGINNING TO DEVELOP ACROSS SRN OH. AS THE STORMS
EXPAND AND MOVE NEWD...A LARGE HAIL...WIND DAMAGE AND ISOLATED
TORNADO THREAT WILL LIKELY DEVELOP OVER THE NEXT FEW HOURS. A WW
SHOULD BECOME NECESSARY LATER THIS MORNING ACROSS THE REGION.

WATER VAPOR IMAGERY CURRENTLY SHOWS AN UPPER-LOW OVER SRN MI WITH A
POTENT TROUGH EXTENDING SWD ACROSS THE OH RIVER VALLEY. A STRONG
BAND OF LARGE-SCALE ASCENT ASSOCIATED WITH THE TROUGH WILL SPREAD
NEWD ACROSS ERN OH INTO WRN PA LATE THIS MORNING ALLOWING FOR
THUNDERSTORM ACTIVITY TO EXPAND IN COVERAGE. OTHER STORMS SHOULD
INITIATE ACROSS SW OH AND SPREAD EWD ACROSS THE SRN OH LATE THIS
MORNING. VISIBLE IMAGERY SHOWS PARTIALLY CLEAR SKIES EXTENDING NNEWD
FROM NRN KY ACROSS ERN OH WHICH SHOULD ALLOW FOR QUICK
DESTABILIZATION THIS MORNING. THIS COMBINED WITH STEEP LAPSE
RATES...MODERATE VERTICAL SHEAR AND COLD TEMPS ALOFT SHOULD SUPPORT
A THREAT FOR SUPERCELLS WITH LARGE HAIL. AS THE STORMS INTENSIFY AND
LOW-LEVEL LAPSE RATES STEEPEN...WIND DAMAGE AND AN AND ISOLATED
TORNADO THREAT WILL BECOME POSSIBLE.
