...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe thunderstorms are not forecast tonight across the
contiguous United States.

...central Gulf Coast...
A mid-level trough over the central Gulf Coast this evening will
weaken and move northeast across the southeast U.S. as a closed
mid-level low over the middle MS Valley meanders eastward.  A
pre-frontal squall line extends from AL into the northern Gulf of
Mexico early this evening.  This convective band will continue to
slowly move east across the FL Panhandle this evening.  Generally
weak low to mid-level lapse rates will tend to be sub-optimal for
both strong updraft development and severe-gust potential.  While a
strong gust cannot be ruled out in the short term, it seems the
overall threat for severe thunderstorms will be sufficiently
low---warranting less than 5% severe probabilities.

Elsewhere, very widely spaced thunderstorms are possible over the TN
and OH Valleys overnight and in parts of the Desert Southwest
associated with a vigorous shortwave trough.
