   Areas affected...Northern Georgia into eastern South Carolina

   Concerning...Severe potential...Watch unlikely 

   Valid 181752Z - 181945Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Isolated reports of damaging winds are possible across
   northern Georgia into eastern South Carolina and portions of
   southwestern North Carolina.

   DISCUSSION...Thunderstorm coverage has increased across portions of
   northern Georgia, southwestern North Carolina, and eastern South
   Carolina, as convective temperature has been reached across much of
   the area. Precipitable water values approaching the 90th percentile
   for the region, coupled with meager vertical shear of only 20 kts,
   will result in a localized threat for water loaded updrafts
   collapsing into downbursts capable of severe winds. Overall
   convective organization is expected to remain low, though some
   loosely organized bowing convective segments are possible where
   outflow interactions are favorable. This convective activity will
   then diminish after sunset.
