   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 117
   CONTINUES.
   
   PRIMARY THREAT OF LARGE TO SIGNIFICANT HAIL AND ISOLATED DMGG WINDS
   AND/OR A TORNADO WILL CONTINUE FOR MUCH OF SC.
   
   00Z CHS SOUNDING IS REFLECTING STEEP MID-LEVEL LAPSE RATES OF 7.7
   C/KM...WHICH IN COMBINATION WITH NWLY FLOW REGIME HAS CONTINUED TO
   SUPPORT DISCRETE SUPERCELLS THAT HAVE FREQUENTLY PRODUCED
   SIGNIFICANT HAIL. MODIFIED SOUNDING IN THE WARM SECTOR SOUTH OF A
   WEDGE FRONT WOULD INDICATE POTENTIAL FOR SOME NEAR SURFACE-BASED
   DEVELOPMENT...WHICH MAY BE CONDUCIVE TO ISOLD/LOCALIZED DMGG WINDS
   AND/OR A TORNADO. GIVEN THE NWLY FLOW REGIME AND LOW LEVEL WARM
   ADVECTION...ANTICIPATE STORMS WILL BE MAINTAINED ACROSS SC DESPITE
   RADIATIONAL COOLING...WITH A SEWD MOTION GRADUALLY SHIFTING THE
   THREAT OFFSHORE WITH TIME.
