PLACE...WHILE SEVERAL SMALLER-SCALE FEATURES PROGRESS EWD WITHIN
LARGER CYCLONIC FLOW REGIME.
AS THE MAIN SHORT-WAVE TROUGH MOVES NEWD WITH TIME ACROSS THE
ATLANTIC COAST REGION...COLD FRONT WILL CONTINUE SAGGING SLOWLY SWD
ACROSS THE SERN U.S. AND INTO FL.
...SERN SC/SERN GA/N FL...
AS MAIN ZONE OF UPPER FORCING AND ASSOCIATED STRONGER WINDS ALOFT
SHIFT NEWD INTO THE ATLANTIC...VEERED LOW-LEVEL FLOW INVOF
SWD-MOVING COLD FRONT SUGGESTS ONLY WEAK CONVERGENCE ALONG BOUNDARY.
THOUGH MOIST BOUNDARY LAYER WILL REMAIN IN PLACE S OF FRONT...WEAK

LAYER HEATS DURING THE DAY.
SCATTERED STORMS SHOULD DEVELOP ALONG FRONT...BUT WEAK CONVERGENCE
AND MARGINAL INSTABILITY SHOULD LIMIT STORM INTENSITY. DEEP-LAYER
SHEAR NEAR 30 KT ABOVE THE SURFACE FRONT MAY ALLOW A FEW SOMEWHAT
STRONGER/SUSTAINED UPDRAFTS -- WITH LOCALLY GUSTY WINDS POSSIBLE.
OVERALL HOWEVER...SEVERE THREAT SHOULD REMAIN QUITE LIMITED THROUGH
THE AFTERNOON BEFORE TAPERING OFF COMPLETELY OVERNIGHT.
