   Valid 271200Z - 281200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   No severe weather is expected across the U.S. on Wednesday.

   ...Discussion...
   A fast-moving short-wave trough -- progged to be exiting the central
   and southern Plains region early in the period, will continue
   tracking eastward, clearing the East Coast overnight.  Meanwhile,
   sharp upper troughing will remain aligned roughly along the West
   Coast through the period.  In between, ridging aloft will exist,
   with anticyclonic flow expanding to include most of the U.S. by the
   end of the period, in the wake of the departing eastern system.

   At the surface, high pressure will largely prevail over most of the
   country.  A surface front lying across the Southeast and into the
   Gulf will sag southward with time, as a weak frontal wave moves off
   the southeastern U.S. coast.  Overnight, this front should cross the
   Florida Peninsula, reaching far south Florida and the Keys by
   28/12Z.

   Showers and occasional thunderstorms are expected over portions of
   the Southeast, in the vicinity of the aforementioned surface
   boundary.  Weak instability suggests disorganized -- and for the
   most part elevated -- convection.  Elsewhere, showers will affect
   portions of the West Coast in the vicinity of the nearly stationary
   upper trough, but any sporadic lightning flashes inland should
   remain few and far between, insufficient for inclusion of a 10%
   thunder area.
