   Valid 280100Z - 281200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Organized severe thunderstorms are not forecast through tonight
   across the Lower 48 states.

   ...Synopsis...
   Water-vapor imagery early this evening shows a mid-level shortwave
   trough over the MN Arrowhead/northern WI embedded within a broad
   cyclonic flow regime centered over the Great Lakes.  A flattened
   mid-level ridge extends across parts of the southern U.S. with an
   upper-level low slowly moving west near the TX Big Bend.  A residual
   front is draped from the Carolinas westward with the boundary
   becoming more disjointed across the northwest Gulf Coast and into
   southwest TX.  Mainly general thunderstorm activity is expected
   going forward this evening across the Deep South into TX and the
   Desert Southwest as the loss of heating and convective overturning
   lessens storm coverage and storms weaken.  Storms over the Upper
   Midwest will likely preferentially develop along a weak cold front
   over northern ND/northern MN this evening.  Steep lapse rates may
   contribute to gusty winds with the strongest storm or two, but this
   activity will likely remain limited in intensity/coverage.
