AREAS AFFECTED...NERN GA...SC...SRN NC

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 211650Z - 211745Z

A SEVERE TSTM WATCH MAY BE NEEDED SHORTLY FOR PARTS OF NERN
GA...MUCH OF SC AND POSSIBLY PARTS OF NC.

CLUSTER OF TSTMS DEVELOPING ESEWD FROM ERN TN AND NERN GA WILL MOVE
INTO INCREASINGLY UNSTABLE AIR MASS ACROSS SC AND NRN NC THROUGH
THIS AFTERNOON. ACTIVITY WAS CURRENTLY INCREASING WHERE LIFT ALONG
LEADING CONVECTIVE COLD POOL WAS FOCUSED ALONG RESIDUAL
QUASI-STATIONARY FRONT EXTENDING EWD ACROSS NRN SC. LEE TROUGH ALSO
APPEARS TO BE SHARPENING ALONG THE ERN SLOPES OF THE APPALACHIANS
AND INTERSECTS THE STATIONARY FRONT OVER NWRN SC. THIS AREA COULD
FURTHER PROVIDE A FOCUS FOR TSTM DEVELOPMENT. FRONTAL ZONE LIES
ALONG THE SRN EDGE OF STRONGER MID LEVEL FLOW AND HAS ALSO FOCUSED
GREATER LOW LEVEL MOISTURE. COMBINATION OF SHEAR AND INCREASING
INSTABILITY...COUPLED WITH APPROACH OF CONVECTIVE COMPLEX FROM NERN
GA...SHOULD RESULT IN AN INCREASE IN TSTM COVERAGE AND INTENSITY
OVER THE NEXT SEVERAL HOURS. ENVIRONMENT APPEARS TO SUGGEST
ORGANIZED MULTICELL STORMS WITH SEVERE HAIL AND POSSIBLY SCATTERED
DAMAGING WINDS SPREADING EAST ACROSS NRN SC...AND PERHAPS NEAR THE
SRN NC BORDER AREA...THROUGH THIS AFTERNOON.
