   Valid 071630Z - 081200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are possible from the coastal Carolinas/Delmarva to
   Louisiana today.

   ...Southeast states...
   A band of showers and thunderstorms is sagging slowly southward into
   parts of AL/GA/SC.  Isolated cells along this band have produced
   locally gusty/damaging winds in the past couple hours.  The
   environment downstream of this activity remains similarly favorable
   for gusty winds.  However, trends in radar/lightning/satellite data
   and 12z CAM guidance provides little confidence that convective
   intensity will rise to severe levels this afternoon.  Wind gusts are
   expected to remain below 50 knots, and therefore will maintain the
   ongoing forecast of less than 5% severe probabilities.
