Weekend temperatures will hit triple digits in parts of Southern California – Press Enterprise


A high pressure system is expected to move across Southern California this weekend, bringing extremely high temperatures and humidity, especially inland.

Triple-digit temperatures in the Inland Empire and the Valleys will arrive by Saturday, with extreme heat warnings issued by the National Weather Service in Palm Springs and Coachella Valley over the weekend.

“Saturday will be the hottest day for all parts of the region,” said NWS meteorologist Tyler Salas.

In Fontana, temperatures will climb into the 90s by Friday and drop to 100s on Saturday and Sunday. Residents of San Fernando will feel a similar heatwave in the mid-90s on Friday before peaking at 101 on Saturday.

Moisture carried by the system will bring a slight chance of thunderstorms in the afternoon and early evening in the mountains and deserts early next week. By Thursday afternoon, storms had already hit the Mojave Desert near Victorville and Barstow.

Metro areas in Los Angeles and Orange counties will not reach the same heights as inland communities, but will still experience decent heat.

By Saturday, the Yorba Linda and Anaheim areas will experience conditions in the mid to high 80s on Friday and will reach the low 90s on Saturday and Sunday. Pasadena will hit even higher temperatures, hitting the low 90s on Friday and quickly jumping to highs of 100 for the weekend.

Communities along the coastline will see less dramatic temperatures with more limited nighttime and morning clouds and fog to coastal areas, keeping temperatures in the 70s and 80s.

Inland temperatures are expected to start cooling by mid-week starting Monday, Salas said, but the change won’t be noticeable until Wednesday.
