   MESOSCALE DISCUSSION 1947
   NWS STORM PREDICTION CENTER NORMAN OK
   0621 PM CST SUN NOV 23 2014

   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.
