San Diego County is feeling conditions cooler than a typical August. West of the mountains, only a few inland regions made it into the 80s Thursday. Most areas peaked in the 70s.

This will be the trend through the weekend. Below-average highs will dominate through about Sunday for most of the county. Evening clouds will continue to build into the overnight hours, lingering into the mornings. These will mix faster once daytime highs start to rebound.

That warming will take place next week. Monday and Tuesday's highs track much closer to normal, then Wednesday temperatures will pick up to above-average. This will bring some lower 80s along the coast, with lower 90s for inland valleys and mountains. Deserts will remain mild right around 100º this weekend then jump about 15º by mid-week next week.

While monsoon season is not over yet, monsoon moisture looks to hold off in San Diego County for the next week.

Friday's Highs:
Coast: 71-79°
Inland: 77-84°
Mountains: 75-86°
Deserts: 95-101°
