SPC MESOSCALE DISCUSSION #0021 FOR SRN HALF OF GA THROUGH S CNTRL
SC CONCERNING...SEVERE THUNDERSTORM POTENTIAL...REF WW 5...

VALID 192005Z - 192100Z

DAMAGING WIND AND ISOLATED TORNADOES REMAIN POSSIBLE WITH ORGANIZED
SQUALL LINE AS IT MOVES EWD THROUGH GA INTO SC. BEST TORNADO THREAT
WILL EXIST WITH SUPERCELLS DEVELOPING AHEAD OF THE LINE. 

LINE OF STRONG TO SEVERE STORMS WITH LEWP/BOW ECHO STRUCTURES
CONTINUE EWD THROUGH CNTRL GA INTO SWRN NC AT AROUND 50 KT. OTHER
MORE ISOLATED SUPERCELLS CONTINUE DEVELOPING AHEAD OF THE SQUALL
LINE BUT ARE QUICKLY OVERTAKEN BY THE LINE. DEEP LAYER SHEAR
REMAINS VERY STRONG. HOWEVER...WIND PROFILES REMAIN UNIDIRECTIONAL 
AND HAS TENDED TO LIMIT THE OVERALL TORNADO POTENTIAL SOMEWHAT 
SO FAR BY PROMOTING A LINEAR DOMINANT MODE OF CONVECTION. 

THREAT FOR TORNADOES CONTINUES NEXT FEW HOURS...ESPECIALLY WITH
STORMS DEVELOPING AHEAD OF THE LINE WHERE ATMOSPHERE HAS BECOME
MODERATELY UNSTABLE. BRIEF ISOLATED TORNADOES MAY ALSO BE POSSIBLE
WITH SUPERCELL STRUCTURES EMBEDDED WITHIN THE LINE.
