Southern California could see record-breaking temps amid extreme heat

High heat sparks fire concerns across SoCal

Extreme heat will continue to bear down over Southern California through the weekend.

LOS ANGELES - Southern California is in the midst of a significant heat wave, with temperatures soaring into the mid-90s and triple digits in many communities. 

Extreme heat warnings are in effect for portions of Los Angeles, Ventura, Ontario, Riverside and Orange counties, and these conditions are expected to persist through Saturday night, potentially extending into Sunday. The heat wave is also increasing fire risks in local mountain areas, with humidity potentially leading to sporadic showers and thunderstorms.

What we know:

The heat wave is driven by an area of high pressure swirling around the four corners, locking in the heat and bringing a surge of monsoonal moisture. This moisture is expected to increase the chances of precipitation, particularly in mountain and desert regions. Extreme heat warnings are in place through Saturday, with heat advisories covering much of Orange County and the Inland Empire. Record-breaking temperatures are possible Thursday and Friday, with coastal communities experiencing warmer-than-normal conditions through Friday.
