Triple-digit heat wave to blanket parts of Southern California this week
Summer is only just beginning and with it, another heat wave is on the way for parts of Southern California this week, with inland cities facing temperatures in the triple digits, forecasters said.
A high-pressure system is expected to start building over the region on Monday, with temperatures slowly climbing throughout the week and peaking by Thursday or Friday, according to National Weather Service meteorologist Rich Thompson.
Temperatures will start to creep from the low 80s into the mid to high 80s on Monday and continue to rise into the high 90s and low 100s by Friday around inland Los Angeles County cities, including Woodland Hills and Pasadena.
Coastal communities will be spared from the heat wave, with early morning light fog hanging over the beaches and temperatures lingering in the mid to high 70s for most of the week, Thompson said.
Heading south down the coast, Orange County cities like Huntington Beach and Laguna Beach will also receive some cloud coverage, and temperatures in the mid-70s to low 80s for the majority of the heat spell, said National Weather Service meteorologist Kasey Oswant.
The Inland Empire will feel the brunt of the torridity, with temperatures already in the 90s for some cities on Monday.
“The IE is going to get quite toasty, especially by the end of the week,” Oswant said.
By Tuesday, San Bernardino cities including Fontana and Ontario will climb into the mid-90s and potentially into the triple digits by Thursday, Oswant said. Meanwhile in Riverside County, cities like Moreno Valley and Corona should see similar temperatures that likely will reach into the low 100s by the end of the week.
A heat advisory was in effect starting on Tuesday through Saturday evening for several Inland Empire cities, as well as a heat advisory extending through Sunday evening in Los Angeles County.
Temperatures may begin to cool down by next Sunday, though forecasters said it’s too early to tell whether it would be the end of the heat wave.
