A low pressure system expected to bring rain and cold temperatures to Southern California on Wednesday could deliver a white Christmas to the Antelope Valley.

"With the cold temperatures, snow levels will be down 3,500 to 4,000 feet and snow accumulations are possible in the Antelope Valley," the National Weather Service said.

On Thanksgiving Day, a wintry storm brought the region snow in amounts forecasters said they had not seen since 2011: Palmdale received 3 to 5 inches of powder, while Lancaster got 4 to 5 inches.

Other communities in the High Desert, including Victorville and Apple Valley, also enjoyed some snow.

For Wednesday and Thursday, the Weather Service is forecasting about 1 to 2 feet of snow in the mountains.

The San Gabriel Mountains could receive up to 3 inches of rain, while precipitation totals in other areas will range from one-half to 1 1/2 inches, NWS said.

The agency warned of possible road closures and holiday travel delays, with winter driving conditions expected on the Grapevine, State Route 33, Highway 14, the Cajon Pass, the Ortega Highway, Interstate 9 in San Diego County and other mountain roadways.
