...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms are expected across far southern California
and into Arizona tonight. Severe storms are not expected.

...Discussion...
Recent radar and satellite show that a few isolated thunderstorms
are ongoing near the mid-level low moving inland across
California/southern Arizona.

Isolated to scattered showers and thunderstorms will likely continue
into the evening, spreading further east into central/southern
Arizona as forcing increases inland. Cooling aloft will allow for
modest buoyancy around MLCAPE 250 J/kg across portions of southern
California and southern/central Arizona. Overall, shear profiles
remain weak and severe storms are not expected.
