Rain, thunderstorm chances linger ahead of extreme heat across Southern California

LOS ANGELES (KABC) -- Rain chances are lingering across Southern California as the hot conditions are met with humidity.

Monsoonal moisture has moved into the region, bringing muggy and humid conditions. With that humidity comes rain and thunderstorm chances, especially in our mountain communities.

Rain chances stick around on Monday, and then when skies clear up by Tuesday and another high-pressure system moves in, expect another significant warmup.

Wednesday and Thursday are expected to be the hottest days, with many areas seeing triple-digit heat.

An Extreme Heat Watch has been issued for most of SoCal from Tuesday at 10 a.m. through Thursday at 8 p.m.

Los Angeles and Orange counties on Monday will see a high of 85 degrees and a low of 67, with a 10% chance of rain. A significant warmup begins on Tuesday, with highs peaking in the upper-90s on Wednesday.

The valleys and Inland Empire can expect a 10% chance of rain on Monday, with a high of 94 degrees and a low of 68. As temperatures begin warming up on Tuesday, expect several days of triple-digit heat.

Beach communities on Monday will see a 10% chance of rain with a high of 73 degrees and a low of 67. Highs are expected to peak in the low-80s on Wednesday.

Mountain communities will see a 50% chance of thunderstorms on Monday, with a high of 78 degrees and a low of 52. Thunderstorm chances linger in the forecast all week.

Desert areas on Monday will see a high of 100 degrees and a low of 75, with a 20% chance of thunderstorms. Palm Springs is expected to reach 105 degrees. Thunderstorm chances return later in the week.
