Region to warm slightly, then cool again by weekend

A slight warming trend is expected through mid-week, with gradual cooling for the second half of the week, forecasters said Sunday.

Temperatures are expected to be in the low to mid-80s along the coast through Wednesday, the upper 80s in the inland valleys, mid-80s in the mountains and low 100s in the deserts, forecasters said.

Those highs should drop into the low 70s along the coast heading into next weekend, the low 80s inland, upper 70s in the mountains and mid-90s in the deserts.

An influx of tropical moisture will bring chances of thunderstorms for the middle to end of the week in the mountains and deserts.

“For the middle to end of the week, an influx of tropical moisture from what is now Tropical Storm Mario is expected to move northward,” the National Weather Service said in a forecast discussion. “That influx of moisture will likely disrupt low cloud and fog formation leaving coverage patchy to nonexistent.”

By Wednesday, there is a chance for showers and thunderstorms in the mountains and deserts, with a smaller possibility of rain in the western part of the county.
