...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected.
...CA/Great Basin...
A stationary mid-level low near San Francisco Bay will maintain
cyclonic flow from the eastern Pacific through CA and into the Great
Basin. The associated mid-level cold pocket (-24 to -26 deg C) will
combine with limited diurnal heating to contribute to pockets of
weak, intermittent destabilization. Low-topped convection may yield
some lightning flashes with the stronger updrafts. However, overall
weak and fleeting buoyancy will limit storm vigor and preclude a
severe risk.
Elsewhere, a cold front will continue pushing southeast across the
Southeast states and reach the Carolina coast later today.
West-to-east moving showers and perhaps a few thunderstorms are
possible this afternoon before ceasing by this evening.
