The National Weather Service said Sunday evening to expect snow on some Bay Area peaks Monday morning.
Snow levels will drop to "around 1,000-1,500 feet tonight into Monday morning," the NWS said on its Twitter account. Mountain travel will remain "difficult to impossible," it said, as most passes remain closed into Monday.
Significant snowfall will continue for portions of West Coast mountain ranges and the intermountain west. Expect record cold in parts of Northern California. A steady fetch of Pacific moisture and anomalously cold temperatures through the atmospheric column will support heavy snowfall rates that will continue to blanket the mountain ranges of the West, with an emphasis on areas from the Sierra Nevada to the central Rockies.
The Sierra Nevada, which has already picked up several feet of snow the past few days, is expected to see an additional two to five feet of snow through Tuesday.

Have any weather alerts been issued?
As of Christmas Eve afternoon, there were no weather alerts in effect.
Will the rain cause any problems?
The storms turned deadly Thursday when two bodies were pulled from a submerged car stuck in a flooded underpass in Millbrae.
Before the storms arrived, the weather service said the rain could cause minor flooding in low-lying areas and spots where drainage is poor, slick roads and ponding in areas, as well as rockslides and landslides.
"Good news is that rain totals are spread out over many days which should mitigate major impacts," the weather service's Bay Area office said in a tweet. "But be prepared for minor flooding, slick roads, and potential for debris flows/mudslides."
What's the weather forecast for the Sierra Nevada?
Several feet of snow is expected to fall in the Sierra this week, over the weekend and into next week, likely causing headaches for travelers heading to the mountains for the holidays.
The weather service said mountain travel is "highly discouraged" through the weekend and into next week.
