Climate service posts map exhibiting the place snow may fall in San Francisco Bay Space on Tuesday
Snow fell on the highest peaks around the San Francisco Bay Area early Sunday, and more fresh powder is on the way next week with the potential for flurries in the inland valleys, the National Weather Service said. Mount Diablo in the East Bay could see over 6 inches of snow Sunday through Tuesday.
“In the next three days or so, precipitation on these higher peaks will most likely come in the form of snow,” said Roger Gass, a weather service forecaster. “We are seeing an increase in precipitation tonight through tomorrow as this cold front moves through the region on Monday.”
While snow is expected in select locations in the Bay Area (see map below), the rest of the region will continue to experience isolated showers through Wednesday.

The cold front targeting the Bay Area is coming from western Canada and will flood the region with freezing air. Monday night through Tuesday morning brings the highest probability of snow reaching valley floors in 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 flurries to surface, but in places along the bay front like San Francisco that seems highly unlikely,” Gass said.
If snow falls on valley floors, Gass said, it probably won’t stick to the ground.

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