An excessive heat warning for the deserts of San Diego County will remain in effect until 8 p.m. Sunday, according to the National Weather Service.

Dangerously hot conditions were expected in Borrego Springs, with temperatures up to 116 degrees possible.

The weather service said a large area of high pressure over the Southwest will cause hot summer weather inland, and a monsoonal, southeast flow over Southern California, with isolated thunderstorms possible in the mountains.

High temperatures on Sunday were predicted to be 73 to 78 degrees along the coast, 84 to 89 in the wester valleys, and 93 to 98 near the foothills, 91 to 99 in the mountains and 110 to 116 in the deserts.

“It’s looking like a cooler and drier trend next week with temperatures back to normal by Tuesday for coast to mountains, remaining a little above normal in the deserts,” forecasters said.
