The week before Christmas will begin with mild weather in San Diego, but rain and mountain snow are expected by midweek, the National Weather Service said.
“Low pressure off the California coast, and a ridge over the Southwest will steer Pacific moisture over SoCal this week,” the weather service said. “Expect some rain by Thursday…and more rain and snow over the Christmas weekend into early next week.”
It was a cold Sunday morning across Southern California. Many locales dropped into the 30s overnight, including some beach areas, such as Del Mar and Solana Beach.
A frost advisory was issued from 10 p.m. Sunday to 8 a.m. Monday for San Diego County deserts.
Some fog was expected to return to coastal areas overnight, followed by increasing high clouds Monday and Tuesday ahead of the Pacific storm system.
Highs on Monday are forecast to be 60 to 65 near the coast, 66 inland, 66 to 71 in the valleys, 56 to 64 in the mountains and 66 to 71 in the deserts.
Widespread rain and high elevation snow should arrive onThursday, forecasters said. Showers and cooler weather may linger for the remainder of the holiday weekend in a persistent stormy pattern.
On Thursday, the snow level was expected to begin to drop and was forecast to be between 5,000 and 6,000 feet Friday morning.
Look for widespread rainfall across the county of 1-3 inches by late Friday, mountains favored for the heavier amounts, the weather service said.
