AREAS AFFECTED...EASTERN GA AND PIEDMONT/COASTAL PLAIN AREAS OF NC
AND SC

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 291752Z - 291945Z

POTENTIAL FOR ISOLATED DAMAGING WINDS/SOME LARGE HAIL IS EXPECTED TO
INCREASE OVER THE NEXT SEVERAL HOURS ACROSS EASTERN GA INTO THE
PIEDMONT/COASTAL PLAIN AREAS OF BOTH NC AND SC. ALTHOUGH NOT
CURRENTLY ANTICIPATED...WILL MONITOR FOR A POSSIBLE SEVERE
THUNDERSTORM WATCH.

WATER VAPOR/VISIBLE SATELLITE IMAGERY FEATURES WELL DEFINED MID
LEVEL CIRCULATION MOVING EASTWARD ACROSS THE NC/SC APPALACHIANS
EARLY THIS AFTERNOON. ON THE PERIPHERY OF THIS FEATURE...AMPLE
INSOLATION/TEMPERATURES WARMING INTO THE LOWER 90S AMIDST A
RELATIVELY MOIST AIRMASS IS LEADING TO A EROSION OF SURFACE BASED
CINH ACROSS EASTERN GA AND PIEDMONT/COASTAL PLAIN AREAS OF NC/SC
EARLY THIS AFTERNOON. SCATTERED TO NUMEROUS THUNDERSTORMS APPEAR
LIKELY TO DEVELOP OVER THE NEXT SEVERAL HOURS...ATTRIBUTABLE TO
DIFFERENTIAL HEATING/MID LEVEL IMPULSE ASSOCIATED ASCENT...IN
ADDITION TO THE COASTAL SEA BREEZE.

WSR-88D VWP FROM GREENVILLE-SPARTANBURG CAPTURES ENHANCED LOW TO MID
TROPOSPHERIC FLOW VIA THE MID LEVEL CIRCULATION...WITH 25-35 KT
WESTERLY WINDS EVIDENT BETWEEN 1-6 KM. THIS MODESTLY ENHANCED
VERTICAL SHEAR WILL LIKELY PROVIDE SOME ADDITIONAL
FOCUS/ORGANIZATION FOR STRONG TO SEVERE THUNDERSTORMS THIS AFTERNOON
AS THE MID LEVEL CIRCULATION SPREADS EASTWARD. THE STRONGEST STORMS
WILL BE CAPABLE OF DAMAGING DOWNBURSTS/SOME LARGE HAIL/LOCALLY HEAVY
RAINFALL.
