STORMS WILL DEVELOP AND BECOME NUMEROUS THIS AFTERNOON WITH A THREAT
OF HAIL AND LOCALLY DAMAGING WIND GUSTS.

STRONG HEATING IS UNDERWAY WITH TOWERING CU NOTED ON VISIBLE
IMAGERY. MODIFIED OBSERVED AND FORECAST SOUNDINGS SHOW STRONG
INSTABILITY IN PLACE WHICH WILL ALLOW FOR VIGOROUS UPDRAFTS. WIND
SHEAR PROFILES ARE RELATIVELY WEAK AND GENERALLY FAVOR PULSE
CONVECTION. HOWEVER...VEERING LOW LEVEL WINDS IN THE LEE OF THE
APPALACHIANS ALONG WITH STRONG HEATING AND INSTABILITY WILL ALLOW A
FEW CELLS TO BECOME MULTICELLULAR WITH A FEW LONGER LIVED CORES.
LARGE HAIL AND STRONG WIND GUSTS WILL BE LIKELY. HAIL ANALOGS
PRODUCED FROM BOTH NAM AND RUC MODEL SOUNDINGS INDICATE THE MOST
LIKELY HAIL SIZE WILL BE FROM 0.75 - 1.00 INCH WITH ISOLATED
1.50-1.75 INCH STONES POSSIBLE.
