The record breaking temps comes as the Southland, along with much of the Western U.S., continues to sizzle under a sweltering heat wave.
The high pressure system over the Southwestern United States remains in place and will keep most of the region blazing hot through Saturday, forecasters said. A separate wave of high pressure is rotating through Southern California, bringing a slight chance of rain showers throughout Riverside County Friday morning.
The system will begin weakening on Sunday, when temperatures are expected to begin subsiding, the weather service said.
