SVR THREAT SHOULD NOT EXTEND MUCH EAST OF WW 225 ACROSS NERN GA AND
THUS A NEW WW IS NOT EXPECTED. SVR WIND/HAIL THREAT WILL BE MAINLY
CONFINED OVER ERN/SRN PORTIONS OF WW 225 FOR THE NEXT 1-2 HRS.

MARGINAL SVR THREAT JUST EAST OF WW 225...BUT AREAL EXTENT OF MODEST
INSTABILITY SHOULD BE LIMITED TO ONLY A 1-2 ROWS OF COUNTIES EAST OF
WW 225 AS STABLE AIR REMAINS OVER NERN/ECENTRAL GA SUPPORTED BY ELY
LOW LEVEL FLOW.

FURTHER WEST...ALTHOUGH AIRMASS IS WORKED OVER ACROSS NWRN GA BEHIND
THE CONVECTIVE LINE...INCREASING LOW LEVEL SSWLY WINDS ATOP
MESO-HIGH OVER NWRN GA MAY SUPPORT A MARGINAL HAIL THREAT FOR THE
NEXT FEW HRS WITH ANY ADDITIONAL NEW TSTM DEVELOPMENT. THIS AREA MAY
BE CLEARED FROM WW 225 BY 02Z IF NEW TSTM INITIATION FAILS TO OCCUR
BEFORE THEN.
