   CONTINUES.
   
   SUMMARY...THREAT FOR DMGG WIND/HAIL NOW PRIMARILY CONFINED TO SRN
   SC...WHILE THE AIR MASS HAS STABILIZED OVER MOST OF FAR SERN GA WITH
   A SUBSEQUENT REDUCED SVR THREAT. WW CAN BE CLEARED BY WFO CHS FROM

   DISCUSSION...SFC OBS SHOW WINDS VEERING IN WAKE OF ENEWD MOVING
   CONVECTION ALONG PRE-FRONTAL WEAK SFC TROUGH. AIR MASS APPEARS TO
   HAVE STABILIZED OVER MOST OF FAR SERN GA AND INTO FAR SWRN SC...WITH
   PRIMARY THREAT NOW FOCUSED NE OF BEAUFORT/HAMPTON COUNTIES SC.
   POCKETS OF ENHANCED INSTABILITY /MLCAPE VALUES NEAR 1500 J/KG PER
   RECENT OBJECTIVE ANALYSIS DATA/ WHERE TEMPERATURES HAVE REACHED THE
   LOWER 80S SHOULD SUPPORT CONTINUED DEVELOPMENT OF MULTICELL CLUSTERS
   CAPABLE OF PRODUCING ISOLATED DMGG WIND/HAIL. THE THREAT COULD
   EXTEND TO THE N/E OF THE ONGOING WW AREA FOR THE NEXT 1-2 HRS...BUT
   WITH THE ONSET OF DIURNAL COOLING...A GENERAL DOWNTREND IN TSTM
   INTENSITY IS EXPECTED TO OCCUR AS WATCH EXPIRATION TIME OF 01Z
   APPROACHES. THUS...AN ADDITIONAL WW IS NOT ANTICIPATED BEYOND THIS
   TIME.
