NEXT CHANCE FOR RAIN SAN DIEGO: UPDATED SUNDAY 9/13/2015

Scattered showers and thunderstorms will be possible from Monday afternoon into Tuesday.

The air will be warm and humid, which makes the atmosphere unstable. You can see the SFC CAPE levels (instability parameter) on the map below. A weak disturbance in the upper atmosphere will pass the area and spark the formation of showers and isolated thunderstorms.

The strongest storms will bring heavy downpours and lightning/thunder. These storms will be hit-and-miss, so not every area will see the heavy rain. Regardless, you should be prepared for the possibility of poor driving conditions during the Monday evening commute.

A stray shower is possible Monday morning, however, the best chances for rain will be from 3 PM Monday through 8 AM Tuesday. Another round of showers and thunderstorms could again pop up on Tuesday afternoon.
