...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not forecast through tonight.

...Synopsis and Discussion...
Longwave upper troughing with multiple embedded mid-level
perturbations over the eastern CONUS and Canada will maintain
surface high pressure and offshore/continental low-level
trajectories across the Southeast through tonight. A separate
shortwave trough will continue to progress eastward over the Great
Basin and northern/central Rockies/Plains today. Negligible
instability across all these regions will preclude thunderstorms.
