...NO SEVERE THUNDERSTORM AREAS FORECAST...

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

...Discussion...
A potent mid to upper-level low west of southern CA will move east
and evolve into an open trough and reach the AZ-NM/Sonora-Chihuahua
border vicinity by early Wednesday morning.  Isolated to widely
scattered showers associated with the cold core will spread east
during the day from southern CA into the lower CO Valley and
southwest AZ, and later into the Sonoran Desert/Mogollon Rim
tonight.  Deeper convection near and east of the mid-level cold
pocket will probably result in occasional lightning flashes.
Elsewhere, quiescent conditions for thunderstorm activity will
prevail.
