AREAS AFFECTED...WRN SC...WRN NC...FAR ERN TN

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 212322Z - 220045Z

THE THUNDERSTORMS DEVELOPING ACROSS THE WRN CAROLINAS AND NERN GA
WILL LIKELY MAINTAIN A SEVERE THREAT OVER THE NEXT FEW HOURS. LARGE
HAIL AND WIND DAMAGE SHOULD BE THE PRIMARY THREATS.

SFC ANALYSIS CURRENTLY SHOWS A MOIST AXIS EXTENDING NWD ACROSS ERN
GA INTO WRN NC WHERE DEWPOINTS ARE IN THE LOWER 60S F. LOW-LEVEL
CONVERGENCE ALONG THE MOIST AXIS AND SFC HEATING IS RESULTING IN
THUNDERSTORM DEVELOPMENT. STORMS SHOULD REMAIN RELATIVELY ISOLATED
THIS EVENING DUE TO A LACK OF LARGE-SCALE ASCENT ACROSS THE REGION
ASSOCIATED WITH AN UPPER-LEVEL RIDGE. HOWEVER...FORECAST SOUNDINGS
SHOW MODERATE INSTABILITY REMAINING IN PLACE THIS EVENING WITH STEEP
LAPSE RATES AND SUFFICIENT SHEAR FOR A SEVERE THREAT WITH LARGE HAIL
AND ISOLATED WIND DAMAGE. DUE TO THE WEAK ASCENT...THE ACTIVITY
SHOULD DECREASE IN INTENSITY AFTER SUNSET AS SFC TEMPS COOL AND
INSTABILITY DECREASES ACROSS THE REGION.
