Much of California is expected to bake this weekend as the first major heat wave of the summer will send temperatures into the triple digits in several regions, stoking fears of wildfires sparked by Fourth of July festivities.
The incoming system will arrive in Southern California on Wednesday evening, and the mercury will begin to climb in earnest Thursday and into next week, the National Weather Service said. The hottest temperatures are expected across interior portions of the region Saturday and Sunday.
In those areas, daytime temperatures are predicted to reach the high 90s and low 100s in the desert, lower mountains and interior valleys. The warmest portions of Los Angeles County valleys could see 100 degrees by Saturday, while the interior valleys of San Luis Obispo County and the Antelope Valley could climb to 107.
