   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 308 CONTINUES.
   
   THREAT FOR ADDITIONAL SVR THUNDERSTORM DEVELOPMENT WILL CONTINUE FOR
   ANOTHER HR...BEFORE LOSS OF HEATING ENDS ANY ADDITIONAL SVR THREAT.

   LATEST CHS RADAR IMAGERY SHOWS A WELL DEFINED SEA-BREEZE/DRYLINE
   BOUNDARY INTERSECTION OVER SRN COLLETON COUNTY IN FAR SERN SC SWWD
   INTO JASPER COUNTY. THIS BOUNDARY INTERSECTION IS WHAT AIDED IN A
   SUPERCELL TO DEVELOP /PRODUCING A TORNADO RECENTLY INVOF OF CHS/.
   ALTHOUGH DAYTIME HEATING WAS WANING...SUFFICIENT CONVERGENCE ALONG
   THIS BOUNDARY INTERSECTION WAS SUPPORTING MDT/TCU PER VIS SATELLITE
   IMAGERY. SUFFICIENT CONVERGENCE MAY SUPPORT ANOTHER SVR TSTM TO FORM
   FROM THE FAR SERN SC COASTAL COUNTIES SWD INTO THE COASTAL COUNTIES
   OF FAR SERN GA IN THE NEXT HR. GIVEN THE STRENGTH OF LOW LEVEL SHEAR
   EAST OF THE SEA-BREEZE FRONT /0-1 KM SHEAR OF 36 KTS PER THE

   WHICH COULD FORM OVER THIS AREA.
