AREAS AFFECTED...SERN GA...SRN SC

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 240021Z - 240145Z

PROBABILITY OF WATCH ISSUANCE...60 PERCENT

SUMMARY...BRIEF TORNADO AND ISOLATED DAMAGING WIND RISKS CONTINUE
ACROSS THE SAVANNAH VALLEY. CONTINUING TO MONITOR FOR A POSSIBLE
TORNADO WATCH ISSUANCE WITH CONCERN FOR A SEMI-DISCRETE SUPERCELL OR
TWO TRACKING TOWARDS COASTAL SC.

DISCUSSION...A DISCRETE STORM NEAR THE LONG/WAYNE COUNTY BORDER IN
GA HAS RECENTLY INTENSIFIED IN MID-LEVEL REFLECTIVITY ALONG WITH
DEVELOPMENT OF SUPERCELL STRUCTURE. THIS STORM APPEARS TO HAVE THE
BEST CHANCE TO FURTHER INTENSIFY GIVEN ITS STORM MODE ON THE NRN
PERIPHERY OF UPPER 60S SURFACE DEW POINTS. ALTHOUGH LOW-LEVEL WINDS
HAVE VEERED IN TIME-SERIES OF CLX VWP DATA...0-1 KM SHEAR HAS
INCREASED TO NEAR 50 KT. THIS VERY STRONGLY-SHEARED ENVIRONMENT MAY
YIELD MULTIPLE HOURS OF SUPERCELL STRUCTURE...SUPPORTED BY 23Z HRRR
GUIDANCE. ISOLATED DAMAGING WINDS AND A TORNADO WILL REMAIN
POSSIBLE.
