Extreme heat arrives in Southern California. Here's how hot it will get

LOS ANGELES (KABC) -- Extreme heat sticks around in Southern California on Wednesday before relief arrives by the end of the week.

Wednesday is expected to be the hottest day of the week, with many areas seeing triple-digit heat.

With subtropical moisture 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.

Then, another Weather Change Alert is in place next Tuesday as a chance of rain re-enters the forecast.

Los Angeles and Orange counties on Wednesday will see a high of 96 degrees and a low of 69. Highs are expected to drop to the low-to-mid 80s by Friday and through the weekend.

The valleys and Inland Empire on Wednesday can expect extreme heat with a high of 107 degrees and a low of 67. A couple more days of triple-digit heat are ahead before temperatures begin to fall on Friday.

Beach communities on Wednesday will see a high of 83 degrees and a low of 68. Highs are expected to drop back to the mid-to-upper 70s by this weekend.
