   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 512
   CONTINUES.
   
   WITH EARLIER SEVERE TSTMS HAVING RAPIDLY WEAKENED ACROSS PORTIONS OF
   UPSTATE SC...RENEWED TSTM DEVELOPMENT APPEARS UNLIKELY WITHIN WW 512
   PRIOR TO 00Z SCHEDULED EXPIRATION. CONVERGENCE APPEARS TO HAVE
   WEAKENED ALONG REMNANT OUTFLOW BOUNDARY FROM TSTMS THAT ARE NOW OFF
   THE CAROLINA COUNTY AND CU FIELD CONTINUES TO DIMINISH IN VISIBLE
   SATELLITE IMAGERY. ALTHOUGH AIR MASS REMAINS STRONGLY UNSTABLE S OF
   THE BOUNDARY...LACK OF APPRECIABLE FORCING MECHANISMS SUGGEST THE
   SEVERE THREAT SHOULD BE MINIMAL THROUGH 00Z.
   
   ADDITIONAL STRONG TO SEVERE TSTMS ONGOING ALONG THE KY/TN BORDER
   COULD EVENTUALLY PROPAGATE E/SEWD AND AFFECT PORTIONS OF THE SRN
   APPALACHIANS LATER THIS EVENING.
