Temperatures ramped Friday, reaching the low 100s -- 6 to 8 degrees above normal -- in the San Fernando and Antelope valleys by the weekend because of high pressure. It's only going to get warmer Saturday and Sunday.

Overnight temperatures won't offer much relief.

Some of Los Angeles County's cooling centers will be open this weekend with health safety protocols due to the pandemic.

The warmest LA County location over the weekend will be the Antelope Valley, where temperatures will sizzle at 100 to 107 degrees.

A strong system of high pressure is building over Arizona and New Mexico, spurring sweltering heat in most of Southern California through Monday.

That's potentially dangerous heat, so residents are encouraged to drink water, limit outdoor activity if possible ad exercise during the morning or evening hours.

A heat advisory will be in effect Saturday morning through Sunday evening for the San Fernando, San Gabriel and Santa Clarita valleys and the San Gabriel and Santa Monica mountains.

In Riverside County, triple-digit heat is expected across a widespread area through Sunday. Highs in the Coachella Valley could soar to 119 degrees on Sunday, while the mercury in the Riverside area could reach 106.

On Sunday, Thermal is expected to reach 118, and Palm Springs 117, and both temperatures would break records in their respective cities for the year. Palm Springs hit 115 on June 3 and again on July 5, and Thermal topped out at 115, too, also on June 3.
