AREAS AFFECTED...NE GA...WRN SC...WRN NC AND SW VA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 091520Z - 091745Z

SCATTERED STORMS ARE EXPECTED TO CONTINUE DEVELOPING AND INTENSIFY
ALONG THE SRN APPALACHIANS AND FOOTHILLS AREAS. ISOLATED LARGE HAIL
AND DAMAGING WIND GUSTS MAY ACCOMPANY THE STRONGER STORMS.

VISIBLE IMAGERY SHOWS CUMULUS ALREADY STARTING TO DEVELOP OVER THE
MOUNTAINS OF WRN NC. AN ISOLATED STORM HAS ALSO DEVELOPED ALONG A
SUBTLE BOUNDARY NEAR GREENSBORO. THE 12Z SOUNDINGS FROM ROANOKE AND
GREENSBORO SHOW STEEP LAPSE RATES IN PLACE. STRONG HEATING WILL
CONTINUE TO DESTABILIZE THE ATMOSPHERE AND ENHANCE OROGRAPHIC
FORCING. VERTICAL SHEAR IS WEAK...BUT THERMODYNAMIC PROFILES APPEAR
SUFFICIENT FOR PULSE SEVERE STORMS. MLCAPE FROM 1500 TO 2000
J/KG...COLD AIR ALOFT AND STEEP LAPSE RATES WILL CONTRIBUTE TO
THREAT FOR LARGE HAIL. ISOLATED DOWNBURSTS WILL ALSO BE POSSIBLE.
