   Areas affected...South Carolina into far eastern Georgia

   Concerning...Severe Thunderstorm Watch 459...

   Valid 260007Z - 260200Z

   The severe weather threat for Severe Thunderstorm Watch 459
   continues.

   SUMMARY...An loosely organized MCS will continue to pose a damaging
   wind threat for the next several hours into southern South Carolina
   and far eastern Georgia.

   DISCUSSION...Regional radar imagery has shown an uptick in
   convection as two clusters begin to merge across central SC. The
   confluence/merging zone of the two outflow boundaries will locally
   enhance low-level ascent, and will likely result in a corridor of
   very strong convection over the next hour or so. Correspondingly,
   there will likely be a downstream corridor where severe/damaging
   wind gusts and/or surging outflow will be more likely owing to
   enhanced water-loading from the stronger convection. Away from this
   corridor, damaging wind gusts will remain likely as the cold-pool
   driven MCS continues to propagate to the south/southwest. Assessment
   of latest surface observations and high-res guidance suggests that
   the MCS will likely propagate along and east of a weak surface
   confluence zone/buoyancy gradient into eastern GA over the next 2-3
   hours.
