San Francisco Bay Area To Be Drenched By Storm Crossing The Pacific Arriving Wednesday

After a week of mostly dry conditions and sidewalk-wetting rain in the Bay Area, a robust storm has entered the forecast and is expected to hit late Wednesday and soak the region into Thursday. This will be the strongest and wettest storm to hit the region in over a week, but before it arrives, another weak system will be coming through.

A small and cold system is expected to arrive in the North Bay late Monday afternoon and spread south into the central Bay Area overnight. Most areas will likely see less than .25 inch of rain through Tuesday morning.

The next storm forecast to sweep the Bay Area is currently developing south of the Aleutian Islands off Alaska and will impact the region with widespread rain and gusty winds from late Wednesday through Thursday.

“Before the storm gets here, the winds will be cranking up from the south,” said Rick Canepa, a forecaster with the National Weather service. “At first, the winds will be on the immediate, 20 to 30 mph winds, and then they’ll mix into the atmosphere and be more widespread. Could be close to wind-advisory levels.”

Widespread moderate rain rates are expected as the system sweeps from north to south and there could be brief periods of heavy rain. Rain will change to showers by Thursday afternoon, before tapering off by late Thursday evening.

“Rainfall totals from late Wednesday through Thursday night are forecast to range from a half inch to an inch in most areas, with as much as 2 inches
possible in the coastal mountains,” according to the NWS.

A cold air mass will spread across the region when the precipitation arrives Wednesday night and a dusting of snow is possible on Bay Area mountaintops at 3,500 feet and above, including on Mount Hamilton in the South Bay and Mount St. Helena in the North Bay.

Temperatures will be unseasonably cool this week with daytime highs in the 50s and overnight lows in the 30s and 40s.
