Southern California is warming up this week

Higher temperatures – triple digits in some areas – are coming to Southern California this week and will last through Saturday, according to the National Weather Service.

High pressure and shrinking marine clouds will aid in warming Orange, Los Angeles, San Bernardino and Riverside counties.

Highs in inland Orange County and Los Angeles county will be around 95 to 100.

Orange County will be slightly cooler, but areas away from the coast will be sweating: Laguna Hills will be 95 degrees on Saturday, July 8, while Yorba Linda should reach 98 degrees. Along the coast, temperatures will peak in the mid-70s and skies will remain mostly sunny.

Inland areas in Orange County were already warm Wednesday, July 5: Santa Ana is projected to hit 89 degrees and Yorba Linda, 95. The coasts are cooler at 75 degrees in Huntington Beach and Dana Point. All areas are sunny with a light breeze reaching only about 5 miles per hour.

It’s likely there will be an excessive heat warning for the Inland Empire Friday, July 7, and Saturday, July 8, and possibly a heat advisory in parts of the mountains. Saturday is expected to be the hottest day when highs could climb into the 115-to-120 range in the low deserts, and 105 to 110 in the high deserts and Inland Empire.

Barstow in San Bernardino County will peak at 110 degrees on Saturday. On that day, Riverside should get to 106 degrees.

Temperatures in Los Angeles County are expected to be especially high.

Near the USC campus, it’s expected to reach 97 degrees on Friday and 95 on Saturday. On those days, Palmdale will get to 102 degrees.

“The high will strengthen on Friday and Saturday for record-breaking heat,” the National Weather Service said in its forecast statement. There was an Excessive Heat Advisory in Los Angeles already on Wednesday.

Temperatures will begin to cool Sunday and continue lower on Monday and into next week.
