SAN DIEGO - Afternoon and evening thunderstorms will be possible Friday in the San Diego County mountains.

A slight chance of showers and thunderstorms over the mountains is in Friday's forecast amid hot weather, and the downpours may move into the deserts on Saturday and the valleys on Sunday, according to the National Weather Service.

Forecasters said weakening high pressure combined with increased monsoonal moisture would bring "increasing chances for afternoon and early evening showers and thunderstorms, mainly for the mountains and deserts" through early next week. The risk of flash flooding is expected to increase Sunday and Monday.

In the forecast for Friday are highs of 76 to 81 degrees near the coast, 82 to 87 degrees in inland coastal areas, 85 to 90 degrees in the western valleys, 93 to 98 degrees near the foothills, 94 to 101 degrees in the mountains and 110 to 115 degrees in the deserts.
