Light rain and misty conditions are in the forecast to start the week in Southern California.
Clouds are locked in throughout most of the region Monday morning as temperatures run up to 10 degrees below normal in some areas. The unusually cool May weather is due to a cold front triggered by a low-pressure system off Northern California.
It has been about 30 days since Southern California last saw measurable rainfall.
