AREAS AFFECTED...CNTRL NC...SC AND SE GA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 042013Z - 042115Z
CORRECTED FOR AREAS AFFECTED
A SEVERE THREAT MAY CONTINUE ACROSS CNTRL NC AND DEVELOP SWD INTO SC
AND SERN GA LATE THIS AFTERNOON. ISOLATED WIND DAMAGE AND HAIL ARE
LIKELY WITH THE STRONGER CELLS. THE THREAT SHOULD REMAIN TOO
MARGINAL TO WARRANT A SEVERE WEATHER WATCH THIS AFTERNOON.
20Z SFC ANALYSIS SHOWS A SFC TROUGH EXTENDING SSWWD ALONG THE LEE OF
THE APPALACHIANS WITH A MOIST AXIS JUST AHEAD OF THE SFC TROUGH WITH
DEWPOINTS IN THE MID TO UPPER 60S F. THUNDERSTORMS ARE DEVELOPING
ACROSS THE REGION IN RESPONSE TO SFC HEATING AND ARE LIKELY BEING
SUPPORTED BY A SHORTWAVE TROUGH INDICATED OVER THE ERN SEABOARD ON
WATER VAPOR IMAGERY. ALTHOUGH INSTABILITY IS NOT THAT
STRONG...WSR-88D VWPS IN THE CAROLINAS SHOW 30 TO 40 KT OF FLOW AT 3
KM SUGGESTING VERTICAL SHEAR IS ADEQUATE FOR SEVERE STORMS. IN
ADDITION...LOW-LEVEL LAPSE RATES ARE VERY STEEP WITH UNIDIRECTIONAL
BOUNDARY FLOW WHICH WILL FAVOR WIND DAMAGE. ISOLATED LARGE HAIL WILL
ALSO BE POSSIBLE BUT RELATIVELY WEAK INSTABILITY SHOULD KEEP THE
THREAT MARGINAL.
