and last updated

It turned into an active evening in the county with thunderstorms in San Diego, Clairemont, and many coastal communties. La Jolla and Campo both picked up about a tenth of an inch on Thursday.

Monsoonal moisture led to unstable conditions and most of the thunderstorm development held off until the evening time. We expect showers and thunderstorms to develop Friday in an isolated fashion, with the best changes far east in our mountains and deserts.

A Heat Advisory remains in effect but it has been extended until Sunday, due to heat related risks. The advisory now includes the inland valleys and mountains. Temperatures will be above average with high humidity increasing the risks through Friday. The weekend will be hot but drier.

Moisture begins to drop on Saturday, with hot and dry conditions into early next week. Elevated fire danger will remain high until Monday.

Temperatures begin trending downward on Tuesday, as a storm system moves into the pacific northwest.

Friday's Highs:
Coast: 75-83°
Inland: 89-96°
Mountains: 88-98°
Deserts: 106-110°
