Valley residents may want to make sure their heater is working, or at least add some extra blankets to their beds this week. Chilly fall weather is expected to continue.
A large mass of cold air from the Gulf of Alaska and British Columbia has moved into Southern California, dropping overnight temperatures into the 40s and bringing light winds. It is the first cold air mass this season to break the persistent high-pressure system that gave the region an extended summer.
"It's not going to be the last one, obviously," said Bruce Rockwell, a meteorologist with the National Weather Service in Oxnard, referring to the cold front.
The new weather system is generating winds of 20 to 30 mph in passes and canyons, Rockwell said. No rain, however, is expected.
Temperatures are not expected to get higher than the 70s for the next few days, but may push into the 80s later in the week as Southern California sunshine warms up the air.
"It's just a law of physics," Rockwell said. "After the cold air mass moves into an area, it takes on the characteristics of the area."
For Monday, the projected high temperature for Burbank, Woodland Hills, and Van Nuys is 79.
