CONCERNING...TORNADO WATCH 820...

VALID 242243Z - 250000Z

LINE OF SUPERCELL THUNDERSTORMS EXTENDS FROM COOSA COUNTY TO
CHEROKEE COUNTY AL.  THESE STORMS ARE MOVING NORTHEASTWARD AT 35
KNOTS AND HAVE A HISTORY OF TORNADOES.  ACTIVITY IS MOVING INTO A
SLIGHTLY MORE STABLE AIRMASS.  HOWEVER...LOW LEVEL WINDS OVER
WESTERN GA REMAIN BACKED IN VICINITY OF WEAK REMNANT SURFACE FRONT. 
LATEST MMX VAD PROFILE SHOWS 3KM SR HELICITY VALUES OVER 400
M2/S2...WITH HIGHER VALUES LIKELY FARTHER NORTH IN NORTHERN GA. 
CURRENT INDICATIONS ARE THAT TORNADOES WILL REMAIN POSSIBLE WITH
THESE STORMS AS THEY TRACK TOWARD THE ATLANTA METRO AREA DURING THE
NEXT 2 HOURS.
