SCATTERED THUNDERSTORMS ARE FORECAST TO DEVELOP DURING THE NEXT FEW
HRS ACROSS ERN KY...SRN WV...SRN/WRN VA...NRN/WRN NC AND FAR NERN
TN. THREAT FOR DAMAGING WINDS AND LARGE HAIL WILL ACCOMPANY THIS
ACTIVITY. AREA IS BEING MONITORED FOR A WW.

SURFACE ANALYSIS AT 17Z SHOWS A COLD FRONT SETTLING SWD INTO THE
CNTRL APPALACHIANS AND MID-ATLANTIC REGION. SURFACE AIRMASS ALONG
AND S OF THE FRONT IS WARMING INTO THE 70S...WHICH IS AIDING IN
RAPID BOUNDARY LAYER DESTABILIZATION. IN ADDITION...A MIDLEVEL
DISTURBANCE LOCATED OVER THE LWR OH VALLEY IS APPROACHING THE
REGION. ASCENT ASSOCIATED WITH THIS FEATURE COMBINED WITH
DESTABILIZING BOUNDARY LAYER AND DEVELOPMENT OF MODERATE INSTABILITY
WILL FAVOR AN INCREASE IN THUNDERSTORM COVERAGE ALONG/AHEAD OF THE
FRONT DURING THE AFTERNOON. AREA RESIDES ALONG THE SRN FRINGE OF
STRONGER MIDLEVEL W-NWLYS...WHICH YIELDS SUFFICIENT DEEP-LAYER WLY
SHEAR FOR E-SEWD MOVING MULTICELL CLUSTERS AND LINE SEGMENTS. THESE
STORMS MAY POSE A THREAT FOR DAMAGING WIND GUSTS AND LARGE
HAIL...AREA WILL CONTINUE TO BE MONITORED FOR A WW.
