   CONCERNING...SEVERE THUNDERSTORM WATCH 178...179...

   VALID 232014Z - 232145Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   178...179...CONTINUES.

   SUMMARY...NEAR-TERM SEVERE RISK EXISTS ACROSS UPSTATE SC WITH LARGE
   HAIL AS THE PRIMARY HAZARD WITH SPLITTING DISCRETE CELLS. SOME OF
   THIS ACTIVITY MAY AFFECT PARTS OF FAR S-CNTRL NC FROM UNION TO
   RICHMOND COUNTIES. ISOLATED STORMS FINALLY APPEAR TO BE FORMING OVER
   THE COASTAL PLAIN WITH LARGE HAIL ANTICIPATED WITH THIS ACTIVITY AS
   WELL.

   DISCUSSION...REPORTED HAIL UP TO GOLF-BALL SIZE CONFIRMED BY WDSS-II
   MAXIMUM HAIL ALGORITHM...HAS OCCURRED WITH MULTIPLE SPLITTING CELLS
   NOW OVER SPARTANBURG/UNION COUNTIES SC. A LONG AND NEARLY
   STRAIGHT-LINE HODOGRAPH SAMPLED BY GSP VWP DATA WILL CONTINUE TO
   FAVOR LEFT/RIGHT SPLITS. EWD EXTRAPOLATION OF THESE CELLS MAY BRUSH
   PORTIONS OF FAR S-CNTRL NC FROM UNION TO RICHMOND COUNTIES WHICH ARE
   CURRENTLY JUST OUTSIDE OF WW/S 178/179.

   1-MIN RESOLUTION VISIBLE SATELLITE IMAGERY AND LIGHTNING STRIKES
   INDICATE INCIPIENT TSTM DEVELOPMENT OVER MARION/FLORENCE COUNTIES OF
   SC. ADDITIONAL CLUMPING CU HAS BEEN NOTED INTO PARTS OF SERN NC.
   WEAKLY-FORCED NATURE OF THE ENVIRONMENT IN THE WAKE OF A NOW
   DISSIPATED MCV OFF THE OUTER BANKS WILL FAVOR DISCRETE CELLS
   PRIMARILY PRODUCING LARGE HAIL AND LOCALLY DAMAGING WINDS. TSTM
   INITIATION ACROSS NRN PORTIONS OF WW 178 APPEARS INCREASINGLY
   UNLIKELY GIVEN THE LACK OF CU AND DRIER SURFACE DEW POINTS /IN THE
   MIDDLE TO UPPER 50S/ RELATIVE TO FARTHER S/SW.
