   Concerning...Severe Thunderstorm Watch 660...

   Valid 062300Z - 070000Z

   The severe weather threat for Severe Thunderstorm Watch 660
   continues.

   SUMMARY...Isolated damaging wind gusts and marginally severe hail
   remain possible across portions of Severe Thunderstorm Watch 660,
   but the overall severe risk is gradually diminishing.

   DISCUSSION...Latest objective analysis indicates an increase in
   convective inhibition to the south of ongoing convection across
   southern/eastern South Carolina where surface temperatures have
   fallen into the 80s F amid widespread cloud cover, outflow from
   prior convection, and waning diurnal heating. This has resulted in a
   gradual weakening of ongoing convection, as noted via recent
   lighting trends, and a gradual decrease in the overall severe risk.
   While this risk will continue to decrease over the next 1-2 hours,
   isolated damaging wind gusts and perhaps an instance of marginally
   severe hail cannot be ruled out with the more robust cores in the
   meantime.
