...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms will be possible tonight in parts of the mid
Mississippi and lower Ohio Valleys, but no severe threat is
expected.

...DISCUSSION...
A shortwave trough, evident on water vapor imagery over the central
U.S., will move eastward across the mid Mississippi Valley tonight.
Isolated thunderstorm development is expected after midnight ahead
of the trough over parts of the mid Mississippi and lower Ohio
Valleys, where surface dewpoints will mostly be in the 40s F. RAP
forecast soundings in the lower Ohio Valley later tonight suggest
that a boundary layer temperature inversion will be in place, which
will keep thunderstorms elevated in nature. Although the stronger
cells could produce gusty winds, instability should be too weak for
a severe threat. Elsewhere across the continental U.S.,
thunderstorms are not expected to develop through tonight.
