Winter is coming! Tuesday is expected to be chilly and mostly dry before the largest storm to sweep the Bay Area so far this year heads into the region Wednesday night. And that’s not the end of it.
The system from the Gulf of Alaska is expected to deliver a potent mix of moderate to heavy rain, high winds, frigid temperatures and low-elevation snow.
“Pretty much since Christmas most of the storms have been relatively low impact, run-of-the-mill systems,” said Scott Rowe, a forecaster with the National Weather Service’s Bay Area office. “This next system that we’re going to see arriving over the next several days is going to be a little stronger.”
When the storm’s frontal boundary arrives Wednesday night, southerly winds are forecast to crank up with gusts up to 40 mph possible in coastal hills. “We might have the need to issue a wind advisory for some locations,” said Rowe. “We’ll be looking at that more closely today.”
The highest rainfall rates are also expected at the front of the storm, and Rowe said there’s some concern about low-level flooding on roads. But he adds major flooding isn’t expected.
“Overall the system isn’t going to hang around for a long amount of time,” he said. “I know a lot of folks remember what happened in the North Bay last year with that strong atmospheric river, but this isn’t going to be one of those events.”
Rainfall totals from late Wednesday through Thursday night are forecast to range from one to two inches in the North Bay and coastal mountains to a half inch to an inch in most other areas, including Oakland and San Francisco.
Temperatures will be unseasonably cool through Friday with daytime highs in the 50s and overnight lows in the 30s and 40s. Temperatures will gradually climb to seasonal averages over the weekend.
