NWS STORM PREDICTION CENTER NORMAN OK
0605 PM CDT SUN MAY 07 2006

AREAS AFFECTED...CNTRL GA THROUGH NORTHEAST FLORIDA AND COASTAL
SOUTH CAROLINA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 072305Z - 080000Z

REMAINING VALID PORTION OF TORNADO WATCH 303 MAY BE ALLOWED TO
EXPIRE AS SCHEDULED AT 00Z.  SEVERE THREAT MAY INCREASE FOR A BRIEF
PERIOD EARLY THIS EVENING ACROSS PARTS OF CENTRAL GEORGIA...BUT A
NEW WW IS NOT CURRENTLY ANTICIPATED.

IN WAKE OF PRIOR CONVECTION...A NARROW CORRIDOR OF MORE STRONGLY
HEATED BOUNDARY LAYER PERSISTS NEAR FRONTAL ZONE ACROSS CENTRAL
GEORGIA...ACROSS THE MACON AREA AND GENERALLY SOUTH OF ATLANTA/
AUGUSTA.  THIS IS STILL CONTRIBUTING TO MIXED LAYER CAPE AS HIGH AS
1000 J/KG...AND FORCING NEAR 50 TO 60 KT 500 MB JET STREAK
ASSOCIATED WITH SOUTHERN STREAM IMPULSE IS SUPPORTING INCREASING
CONVECTIVE DEVELOPMENT TO THE SOUTH AND EAST OF ATLANTA.  EVOLUTION
OF A SMALL ORGANIZED MESOSCALE CONVECTIVE SYSTEM APPEARS POSSIBLE AS
ACTIVITY APPROACHES THE MACON AREA THROUGH 00-01Z.  THIS COULD BE
ACCOMPANIED BY SMALL DEVELOPING SURFACE MESO HIGH/COLD POOL AND
ASSOCIATED POTENTIAL FOR STRONG GUSTY WINDS...IN ADDITION TO RISK
FOR MARGINALLY SEVERE HAIL.  HOWEVER...EAST SOUTHEAST OF MACON...
LIMITED SEVERE POTENTIAL IS EXPECTED TO DIMINISH BY 02-03Z AS
BOUNDARY LAYER STABILIZES MORE RAPIDLY WITH LOSS OF INSOLATION.
