...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected across the contiguous U.S.
through tonight.

...Synopsis/Discussion...
Thunderstorm potential through tonight will be relegated to two
general areas. Across southern Florida and near the eastern Florida
coast, gradual moistening will continue to occur with diurnal
heating and moderate buoyancy (albeit weak mid-level lapse rates)
contributing to thunderstorm potential. In the West, an upper trough
will dig southeastward and approach coastal portions of
Oregon/northern California tonight. As a frontal band approaches and
moves inland, thermodynamic profiles will trend more favorable late
tonight (09-12Z) for the possibility of low-topped convection
capable of lightning.
