   Concerning...Severe Thunderstorm Watch 137...

   Valid 102352Z - 110145Z

   The severe weather threat for Severe Thunderstorm Watch 137
   continues.

   SUMMARY...Scattered severe thunderstorms are expected this evening.

   DISCUSSION...Convection is gradually expanding in areal coverage
   this evening, likely in response to the left-exit region of an
   approaching mid-level speed max. West-southwesterly boundary-layer
   inflow is also contributing, as this trajectory is allowing higher
   instability air mass across northern AL to spread downstream into
   northern GA. Latest radar data suggests the most robust updrafts are
   generating hail, much of it approaching golf ball size.
   Additionally, damaging winds are likely noted as the steepest lapse
   rate plume does extend into this portion of GA. This expanding
   convective corridor will gradually sag southeast as the evening
   progresses.
