   Areas affected...South Carolina...Southern North Carolina

   Concerning...Severe potential...Watch likely 

   Valid 142143Z - 142345Z

   Probability of Watch Issuance...80 percent

   SUMMARY...A severe threat is likely to develop across the eastern
   half of South Carolina and southern North Carolina over the next few
   hours. Wind damage, hail and an isolated tornado threat will be
   possible with the stronger storms. Weather watch issuance will
   likely be needed soon.

   DISCUSSION...The latest surface analysis shows a cold front across
   northern Georgia extending south-southwestward into far eastern
   Alabama. A moist airmass is present ahead of the front extending
   eastward to the Atlantic coast where surface dewpoints generally
   range from the mid 60s to the lower 70s F. In response, the moist
   airmass has become moderately unstable with the RAP showing MLCAPE
   values in the 1000 to 2000 J/kg range. In addition, the Wilmington
   and Charleston WSR-88D VWPs have 0-6 km of 55 to 65 kt with 0-3 km
   storm relative helicities of 250 to 350 m2/s2. This shear
   environment should be favorable for supercells with tornado
   potential and organized multicells with wind damage potential.

   The severe threat should increase across southeastern South Carolina
   over the next hour as severe storms move northeastward out of WW 64.
   Severe storms could also develop further to the north across parts
   of northeastward South Carolina and southern North Carolina.
