...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorm potential appears negligible tonight.

...Discussion..
Pulse thunderstorms earlier this afternoon over the western
Transverse Ranges of southern CA appear to have recently diminished.
Lingering, isolated low-topped convection should decay rapidly after
sunset. Elsewhere across the CONUS, conditions will be too
dry/stable for lightning-producing convection through 12Z Saturday.
