Arctic Weather Settles In for a Week’s Stay
Predawn temperatures plunged into the 30s in parts of Southern California on Monday, and forecasters said it should stay cold all week.
Amy Talmage, a meteorologist with WeatherData Inc., said an arctic weather system that slid into California about two weeks ago is to blame.
“That cold-air mass has remained in place, with only slight modifications, ever since,” she said. “There hasn’t been any warm air moving in to dislodge it, and so far, I don’t see any on the way.”
Talmage said a separate trough of low pressure was edging southward through the state Monday afternoon, bringing rain to the Bay Area and snow to the Sierra, but the precipitation wasn’t expected to reach as far south as Los Angeles.
“That trough is trailed by some more cold air that should keep overnight temperatures in Southern California right where they are,” she said.
Lows before dawn Monday included 35 degrees in San Juan Capistrano, 38 in Santa Ana and 40 in Anaheim and Fullerton. In Los Angeles County, overnight lows were 18 degrees in Lancaster, 20 degrees in Palmdale and 34 in Chatsworth.
Talmage said Orange County’s normal temperature range for this time of year is from highs of 75 degrees to lows of 51 degrees.
