Hot, dry conditions and strong, gusty winds will bedevil Southern California for a few days starting Thursday, creating an “elevated” danger of wildfire through the weekend, the National Weather Service warned.

The hot spell is the product of an upper-level high-pressure system, and its hottest days will be Friday through Sunday, a period likely to be marked by temperature highs in the 90s to low 100s in the valleys and at lower elevations in the mountains, according to a statement on the NWS website.

The Antelope Valley will soar to between 100 and 105 degrees each day during this period. But since it will be dry, without humidity making it feel hotter than it really is, no excessive heat warnings are anticipated as of this morning, according to the NWS.

“The combination of hot temperatures, single-digit humidities, gusty onshore winds, and very dry fuels (vegetation) will bring an extended period of elevated fire danger to Southwest California, especially for the interior valleys, mountains and deserts,” the statement said.

“One area especially susceptible to the gusty onshore winds will be the Highway 14 (Antelope Valley Freeway) corridor from the Santa Clarita Valley into the Antelope Valley, where isolated gusts as high as 45 mph can be expected.”

Gusty northwest winds and dry conditions are also expected along the Interstate 5 corridor in the San Gabriel Mountains in northwestern Los Angeles County every evening through the weekend, it said.

NWS forecasters also warned of an elevated fire danger north of Los Angeles County in the Santa Ynez Range and the Santa Barbara County south coast on Friday evening.

Forecasters urged residents of the region to protect themselves against the high heat by scheduling strenuous activities for early morning or evening.

“Know the signs and symptoms of heat exhaustion and heat stroke and remember that heat stroke is an emergency,” the statement said.

Forecasters and and law enforcement personnel also reminded motorists never to leave a child, senior or a pet in an enclosed parked vehicle, even for a short time.

The NWS forecast highs Thursday of 71 at LAX; 72 in Avalon and San Clemente; 74 in Newport Beach; 76 in Laguna Beach; 79 in Long Beach; 80 in downtown L.A.; 85 in Irvine and Mission Viejo; 86 in Anaheim; 87 in San Gabriel; 88 in Fullerton and Burbank; 90 in Yorba Linda and Pasadena; 91 on Mount Wilson; 96 in Woodland Hills; 97 in Saugus; and 101 in Palmdale and Lancaster.

Friday’s temperatures will be the same as Thursday’s in some communities and up to five degrees higher in others. Temperatures will rise by a few more degrees in much of the region on Saturday.
