VALID 262032Z - 262230Z

PROBABILITY OF WATCH ISSUANCE...5 PERCENT

SUMMARY...ISOLATED STORMS DEVELOPING OVER SC WILL BE CAPABLE OF
DOWNBURST WINDS THROUGH EARLY EVENING. WW IS NOT ANTICIPATED DUE TO
THE VERY ISOLATED AND MARGINAL NATURE OF THE THREAT.

DISCUSSION...THIS AFTERNOON AN ISOLATED STRONG THUNDERSTORM HAS
DEVELOPED OVER NERN SC ALONG THE INTERSECTION OF AN OLD OUTFLOW
BOUNDARY...A STATIONARY FRONT AND SEABREEZE. ADDITIONAL STORMS MAY
DEVELOP FARTHER SOUTH NEAR THE CHARLESTON AREA WHERE VISIBLE IMAGERY
SHOWS AN AREA OF ENHANCED CUMULUS IN VICINITY OF WHAT APPEARS TO BE
THE INTERSECTION OF A SECONDARY OUTFLOW BOUNDARY...THE STATIONARY
FRONT AND SEABREEZE BOUNDARY. DIABATIC WARMING OF THE SFC LAYER HAS
CONTRIBUTED TO MODERATE INSTABILITY IN THIS REGION WITH AROUND 2000
J/KG MLCAPE. A FEW MULTICELL STORMS CAPABLE OF WET DOWNBURSTS WILL
REMAIN THE PRIMARY THREAT INTO THE EARLY EVENING.
