Southern California weather reports show a few more scattered rain showers through Thursday night, but things are expected to dry up — and heat up. Triple-digit temperatures are set to return to parts of the area by Saturday.

National Weather Service meteorologist Stuart Seto tells KPCC, "The showery activity will be basically over by later this evening. However, on Friday, and maybe late Friday night, there could be some thunderstorms in the mountain areas and deserts."

Temperatures are expected to move past 100 in the valleys by Saturday through early next week.

The National Weather Service says a surge in monsoonal flow of moisture is what's bringing scattered light showers to much of Southern California.

Conditions Thursday are expected to be uncomfortably sticky, with most rainfall limited to hit-and-miss big drops.

The upper-level flow from the southeast may also bring a chance of thunderstorms over the mountains and desert through Friday evening.

Forecasters say they do not anticipate widespread flash-flooding but not there is potential for local flooding.

Rainfall across the region in July typically averages a few hundredths of an inch except in the mountains and desert.
