A system of storms gliding across northern California is expected to bring scattered showers to the Bay Area on Sunday and another foot or two of snow to the already covered Lake Tahoe region and northern Sierra Nevada.
The system, which is supposed to last until Sunday night, is the first of two storm fronts predicted to hit Northern California earlier this week, further saturating soil in communities along the San Francisco Bay and creating an impression at high altitude. A second storm is expected to arrive late Monday and continue through Wednesday.
“It will rain at least for the first part of the work week,” said Daial Huang, a meteorologist at the National Weather Service.
The first row of storms late Saturday night brought about a quarter inch to half an inch of rain over much of the Bay Area by 8:30 a.m. Sunday morning. Rain gauges overseen by the National Oceanic and Atmospheric Administration recorded 0.51 inches of rain at the Oakland Museum, while downtown San Francisco recorded 0.67 inches of new precipitation. Mt. Tamalpais he received 0.87 inches of rain.

The interior of the East Bay, which includes most of Contra Costa County, typically received 0.25 to 0.41 inches of rain. Rain shadow effects from neighboring mountains have limited precipitation in the Santa Clara Valley, with San Jose receiving only 0.04 inches of rain. But more rain fell in the nearby Santa Cruz Mountains, and rain gauges showed him 0.35 to 0.69 inches of sediment.
An additional 1/4 inch of rain could hit the coastal areas of the Bay Area on Sunday, with another 1/10 inch likely in the Santa Clara Valley, Huang said. Meanwhile, the East He Bay Hills and Santa Cruz Mountains could see another half-inch to an inch of rain on Sunday.
Clear skies grace the Bay Area on Monday, arriving that evening and should continue into Wednesday before the next weather forecast hits the region. Half an inch of rain is expected along the Bay Area coast. However, 1 to 2 inches of rain is possible in higher elevation areas.
These same storm systems could bury the Sierra Nevada in even more dust. Near-historical snowfall levels that have caused numerous building collapses in recent weeksdespite offering a banner season for ski resorts adjacent to Lake Tahoe.

Cory Mueller, a meteorologist with the National Weather Service, said the northern Sierra should receive another foot or two of snow by early Monday morning. Conditions along Interstate 80 over Donner Pass will deteriorate through Sunday, making travel dangerous.
An additional foot of snow is possible Monday through Wednesday, Mueller said.
“We’re not ready to end the winter here just yet,” Muller said.
