   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe weather will not occur tonight over the Lower 48 states.

   ...Synopsis...
   Progressive flow regime evident in Friday evening water vapor
   imagery will continue through early Saturday.  Surface high pressure
   and quiescent conditions over a large part of the CONUS will prove
   hostile to thunderstorm development.  The exception being near the
   south FL coast in Broward and Palm Beach counties where weak
   convection may yield a couple more lightning flashes this evening
   before diminishing.
