Southern California temperatures expected to climb into the 70s, maybe higher, on Monday

Southern California temperatures on Monday, Feb. 22 are forecast to climb well into the 70s – or higher.

And warm Santa Ana winds that whipped up to about 50 mph across mountains, passes and highways over the weekend are expected to linger through Monday.

A high-pressure system to the west drove the warming trend that by midday Sunday saw temperatures of 76 degrees in Santa Ana, 73 degrees in Long Beach and 70 degrees in Ontario and San Bernardino, according to the National Weather Service.

Monday should be the hottest day of the week, with temperatures 10-15 degrees warmer than average expected in most Southern California valleys and coastal areas, NWS meteorologist Samantha Connolly said.

Highs Monday are forecast at 79 degrees in Van Nuys, 77 degrees in Riverside, 74 degrees in Rancho Cucamonga and 73 degrees in El Segundo. Some valley areas may even see readings in the 80s, according to NWS reports.

Sunny skies should prevail across most of Southern California through the week, meteorologists said. Temperatures will remain warm, but will cool to seasonal averages by the start of the weekend, Connolly said.

This weekend, gusts reached speeds of 57 mph in Browns Canyon north of Chatsworth, 53 mph at the Marshall Peak near San Bernardino, 42 mph in Chino Hills, and 44 mph in Jurupa Valley, according to the weather service.

Powerful winds were likely a factor in eight power outages that happened just in Long Beach over the weekend, and may have contributed to others affecting at least 2,738 Southern California Edison customers, said Ron Gales, a spokesman for the utility.

Meteorologists advised motorists to drive carefully along windswept roads, and warned people to watch out for downed powerlines, falling tree limbs or blown debris. Utility crews had to cut power to an intersection in Sherman Oaks after winds brought a tree down onto a light pole.

Conditions were expected to calm; high wind advisories issued in Los Angeles, Orange, Riverside and San Bernardino counties were set to expire by 3 p.m. Sunday.

Another bout of slightly weaker Santa Ana winds was forecast to develop overnight into Monday morning, and may still prompt advisories in some places, Connolly said. Gusty winds expected in the Santa Clarita Valley and San Fernando Valley and in mountain areas of San Bernardino, Riverside and Orange counties could reach about 50 mph.

No rain was expected in the region, and relative humidity will remain low through Saturday, Connolly said. Winds should remain low after Monday, somewhat diminishing the risk of wildfire in the coming week.
