Valid 130100Z - 131200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected the remainder of tonight into
early Friday.

...01z Update...

Severe probabilities have been removed from the Mid-Atlantic as
earlier strong/severe convection has weakened and moved offshore.
Severe thunderstorms are not expected the remainder of tonight.

Isolated thunderstorms may occur late tonight/early Friday morning
near the southern CA coast as an upper shortwave trough shifts east
across the area. Generally modest low to mid-level flow and weak
instability will preclude severe thunderstorm potential with this
activity.
