Southern California Weather Force has issued a Special Weather Statement effective for the following areas:

Zones:  Eastern half of San Luis Obispo County, Western half of Kern County, including Bakersfield.  Eastern half of Los Angeles County.  The Cajon Pass.  The Inland Empire.  Orange County.  San Diego County.  Los Angeles, San Bernardino, Riverside County Mountains.  Palm Springs.  Western Baja, California.

A storm system moving through the area will begin to bring in colder air aloft.  This will start first in San Diego overnight tonight.  Thunderstorms are possible down there.

As daytime heating happens tomorrow, the combined north to south flow and onshore flow will bring a convergence zone on and south of the Los Angeles and San Bernardino Mountains.  This is a classic setup known to develop thunderstorms there, something the news will call a ‘surprise event’ when it isn’t, and the flow will move them south through the LA, OC, IE, San Diego forecast zones.  Higher elevations can have thundersnow with this setup.

The rest will have hail, wind, funnel/small tornado, and heavy rain risks.

A Thunderstorm Watch may be issued, but if not, you have your forecast.
