COACHELLA VALLEY, CA — As the day's grueling heat hit its peak late Friday afternoon throughout Southern California, temperature-measuring stations in towns across multiple counties began clocking historic high temps, according to the National Weather Service.

The sun came down especially hard on the Coachella Valley, where in the small towns of Palm Desert and Palm Springs, temps had reached 122 degrees by 3:30 p.m. — a full five degrees hotter than the old record.

"A strong upper level high pressure system over the southwest United States along with locally breezy northerly winds at the surface will create dangerous record-breaking heat over much of the area through Saturday," weather officials warned. They said the "potentially life-threatening" heat would "also bring favorable conditions for fire growth."

Only the neighborhoods right up along the Pacific coastline were spared from the day's historically oppressive heat, thanks to a healthy sea breeze cooling them down, meteorologists said.

SoCal's latest heat wave is expected to last through Saturday evening.
