...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not forecast across the U.S. today or tonight.

...Synopsis...
An upper ridge will remain over the southwest states today, with
broad troughing over the east. Dry and stable conditions will
preclude thunderstorms over most areas today, with the only area of
some risk being over southeast FL late tonight. Given the weak
forcing, minimal CAPE, and unfavorable timing, 10% coverage of
thunderstorms is not anticipated.
