Say goodbye to extreme heat! Here's when relief arrives in Southern California

LOS ANGELES (KABC) -- Relief is in sight after several days of extreme heat across Southern California.

We have one more day of weather advisories before a significant cooldown arrives. Despite the cooldown, temperatures will still be fairly hot in much of SoCal.

With subtropical moisture and humidity still in the atmosphere for some areas, rain and thunderstorm chances linger all week for our mountain and desert communities.

An Extreme Heat Warning has been issued for most of the region through Thursday at 8 p.m.

While most of the coastline is not included in the Extreme Heat Warning, those areas are under a Heat Advisory through 8 p.m. on Thursday.

Then, cool air will begin to move in, and temperatures will begin to drop starting Friday. Temperatures will drop about 10 to 12 degrees in some areas.

ABC7 has issued a Weather Change Alert for Friday as the temperatures begin to fall back down to where we should be for this time of year.

Los Angeles and Orange counties on Thursday will see a high of 92 degrees and a low of 68. Highs are expected to drop to the low-to-mid 80s by Friday and through the weekend.

The valleys and Inland Empire on Thursday can expect extreme heat with a high of 102 degrees and a low of 64. Temperatures will drop at least 10 degrees by Friday and stay in that range through the weekend.

Beach communities on Thursday will see a high of 80 degrees and a low of 67. Highs are expected to drop back to the mid-to-upper 70s by this weekend.

Mountain communities will see a 20% chance of thunderstorms on Thursday, with a high of 84 degrees and a low of 52. Thunderstorm chances linger in the forecast all week.

Desert areas on Thursday will see a high of 105 degrees and a low of 68, with a 10% chance of thunderstorms. Palm Springs is expected to reach 110 degrees. Thunderstorm chances stick around the rest of the week.
