...NO THUNDERSTORM AREAS FORECAST...

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

...Synopsis...
Widespread showers are expected to increase ahead of an approaching
mid-level trough across portions of the Ohio and Tennessee Valleys
through tonight. Nonetheless, poor airmass recovery ahead of the
trough suggests that buoyancy will be too low to support any
appreciable lightning flash potential, with no general thunder areas
added to the CONUS.
