Thursday brought much cooler conditions across San Diego. After a couple of record-breaking hot days, highs will gradually cool into the weekend, staying mild for at least the next week.

Thursday afternoon, storms east of San Diego county pushed into our mountains and deserts. Storms did not roll into the valley Thursday, but have the potential to spill over Friday and Saturday. Rain chances linger into Sunday, then dry out into next week.

While the first day of fall was hot, the first full week of fall looks to be pleasant overall. Into the weekend, highs remain mild. Coastal areas will see lower to mid-70s, inland valleys will drop into the lower 80s and mountains will see mid-70s. Deserts will stay just shy of 100º, staying in the double digits.

We're heading into Santa Ana season, so now is a good time to ensure you have defensible space around your home, go over your evacuation plan with your family and ensure your emergency kit is stocked and ready to go.

Friday's Highs:
Coast: 71-80°
Inland: 79-86°
Mountains: 74-86°
Deserts: 91-98°
