Climate service posts map displaying the place snow might fall in San Francisco Bay Space on Tuesday
Snow fell on the highest peaks around the San Francisco Bay Area early Sunday, and there’s more fresh powder on the way with the potential for snow flurries in inland valleys next week, the National Weather Service said. Mount Diablo in the East Bay could see over 6 inches of snow Sunday through Tuesday.
“Through the next three days or so, the precipitation that falls is most likely going to be in the form of snow on those higher peaks,” said Roger Gass, a forecaster with the weather service. “We see an increase in precipitation tonight into tomorrow as that cold front moves through the region on Monday.”
While snow is expected in select locations around the Bay Area (see map below), the rest of the region will continue to see scattered rain showers through Wednesday.

The cold front taking aim at the Bay Area is coming from Western Canada and will blast the region with bone-chilling air. Monday night into Tuesday morning brings the highest chance of snow reaching valley floors in the North Bay and East Bay. Snow levels are expected to drop to 1,000 to 2,000 feet Tuesday morning.
“I think there are parts of the Bay Area that have the potential for a few snow flurries to reach the surface, but in places along the bay front like San Francisco that seems highly unlikely,” Gass said.
If snow falls in valley floors, Gass said, it probably won’t stick to the ground.

Temperatures across the Bay Area are expected to be unusually cold across the next week with daytime highs generally 10 to 15 degrees below normal and overnight lows 5 to 10 degrees below average. Daytime highs on Sunday and Monday will be in the upper 40s in the interior while locations along the bay shoreline, including San Francisco, will struggle to hit 50.
Tuesday is expected to mark the coldest morning of the week, likely bringing the lowest widespread temperatures the region has seen this year. Inland locations will range from the upper 20s to mid-30s, while coastal spots will generally be in the mid-30s to mid-40s. San Francisco could hit a low of 42 degrees on Tuesday, and the city may not break out of the 40s Tuesday afternoon.
