...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected across the continental U.S. through
tonight.

...DISCUSSION...
A large-scale mid-level trough, from the Great Lakes southwestward
into the central states, will move eastward into the mid Mississippi
Valley tonight. At the surface, high pressure associated with dry
and stable air, will remain from the eastern U.S. into the Gulf
Coast region. Further west into the central U.S., a front with cold
and dry air in its wake will advance southward. Due to the dry and
relatively stable conditions over the continental U.S.,
thunderstorms are not expected through daybreak Thursday.
