   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR SOUTH
   FLORIDA...

   ...SUMMARY...
   Strong to locally severe thunderstorms, capable of marginally severe
   wind gusts and hail, will be possible near the southeast Florida
   coast this afternoon.

   ...South FL...
   Visible satellite imagery shows a swelling cumulus field over the
   Everglades and South FL ahead of a southward-progressing cold front
   over the northern part of the Everglades.  A mid-level shortwave
   trough located over the Carolinas/northeast Gulf of Mexico
   --embedded within a larger-scale eastern North America trough-- will
   continue east into the western Atlantic through the evening. 
   Continued warming of a moist airmass across south FL will yield
   moderate destabilization.  Isolated thunderstorms are forecast to
   develop in the vicinity of the front through the mid afternoon. 
   Long, straight hodographs combined with more than adequate CAPE will
   potentially yield a couple of organized storms.  An isolated risk
   for large hail and/or localized damaging gust will be the primary
   hazards with the most intense storms.  This activity will push east
   of the coast by early evening.  

   Elsewhere, quiescent conditions will prevail across a large part of
   the contiguous United States.
