AREAS AFFECTED...ERN GA...ERN SC...ERN NC AND ERN VA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 041739Z - 041915Z

THUNDERSTORMS WILL INCREASE IN COVERAGE AND MOVE SEWD ACROSS THE
REGION. THE STRONGER CELLS SHOULD HAVE A POTENTIAL FOR ISOLATED WIND
DAMAGE AND A WW MAY BECOME NECESSARY ACROSS PARTS OF THE REGION THIS
AFTERNOON.

LATEST VISIBLE IMAGERY SHOWS CUMULUS DEVELOPING ACROSS A WIDESPREAD
AREA FROM THE SRN AND CNTRL APPALACHIANS EXTENDING EWD INTO THE
PIEDMONT OF THE ERN CAROLINAS AND ERN VA. SFC TEMPS HAVE REACHED 95
TO 100 F WITH DEWPOINTS IN THE MID 70S F ALONG THIS CORRIDOR. THIS
IS CONTRIBUTING TO MODERATE TO STRONG INSTABILITY WHICH SHOULD ALLOW
THUNDERSTORMS TO INITIATE AND INCREASE IN COVERAGE OVER THE NEXT 1
TO 2 HOURS. OBJECTIVE ANALYSIS CURRENTLY SHOWS 0-3 KM LAPSE RATES
EXCEEDING 8.0 C/KM ACROSS MOST OF THE REGION WHICH SHOULD BE
SUFFICIENT FOR ISOLATED WIND DAMAGE WITH THE STRONGER CELLS. THE
GREATEST THREAT FOR WIND DAMAGE WILL LIKELY EXIST ACROSS ERN VA
WHERE STRONGER VERTICAL SHEAR EXISTS AND FORECAST SOUNDINGS SHOW
CLASSIC INVERTED-V PROFILES AND UNIDIRECTIONAL FLOW.
