SHORT TERM OUTLOOK VALID 0000-0600Z...MEDIUM-HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...ONGOING WAA/ISENTROPICAL HVY SHIELD PRECIPITATION
REMAINS FOCUSED ALONG THE COASTAL ZONES OF E GA/SC  AND NOW BEGINNING TO
AFFECT S NC AS WARM FRONT LIFTING NORTHWARD HAS ORIENTED PARALLEL TO THE
COAST AND IS ENHANCED BY BOUNDARY OF GULF STREAM.   BOUNDARY LAYER FLOW
IS NEARLY 120 DEGREES OF CONVERGENCE ALONG THE COASTAL BOUNDARY WITH
TPWS IN EXCESS OF 1.75" ALONG THE ENTIRE LENGTH... FROM NNE FLOW ALONG
FROM CAPE FEAR TO SSELY FLOW PARALLEL TO THE FL COAST NEARLY CONVERGING
ON BOUNDARY JUST OFF SHORE HILTON HEAD ISLAND.   MST CONVERGENCE ANALYSIS
VALUES ARE EXTREME... ALLOWING FOR VERY EFFICIENT HVY RAINFALL WITH RATES
IN EXCESS OF 1"/HR.   ALSO... A NARROW RIBBON OF INSTABILITY WITH CAPES
NEAR 1500 J/KG IS ALLOWING FOR DEEPER VERTICAL GROWTH WITH OVERSHOOTING
TOPS SEEN IN FADING VISIBLE IMAGERY FROM HHI DOWN TO OFFSHORE OF KJAX.
GIVEN THE SHARPNESS OF THE BOUNDARY... MUCH OF THE SHIELD IS EVAPORATING
IN EIR ACROSS CENTRAL SC BEFORE ENHANCING AGAIN IN THE FOOTHILLS OF THE
SOUTHERN APPALACHIANS IN THE DEFORMATION ZONE.    ALONG WITH LOCAL TIDES
AND SURGE DUE TO LONG EASTERLY FETCH INTO SC... FF THREAT WILL CONTINUE
FOR THE NEXT 6HRS ACROSS THE SC COAST SHIFTING TOWARD KMYR BY 3-6Z.
