San Francisco Chronicle / October 29, 2021

La Niñas usually bring storms in the Pacific Northwest, but drier conditions in Southern California. That puts the Bay Area “on the periphery of the wetter region,” David King, a meteorologist with the National Weather Service explained — meaning it’s hard to predict how much rain the region might see.

“It depends whether we have a system that drops further south when it materializes,” King said. “It really comes down to the day-to-day forecast.”

King predicted that the central and southern parts of the Bay Area, including the San Mateo coastline, will see average to less-than-average precipitation, while the North Bay is more likely to see more precipitation than usual.

The Climate Prediction Center at the National Oceanic and Atmospheric Administration also predicted that Northern California would see an improvement in drought conditions — but still not enough to pull the region, especially further south towards the Bay Area, out of the drought.

Meanwhile, there's a little moisture in the immediate forecast. According to the link,

This weekend’s rains are expected to remain fairly light, according to the National Weather Service — totals are likely to be about 0.3 inches of rain in the North Bay and 0.1 to 0.2 inches in the East Bay and San Francisco, with little to no rain falling in the South Bay.
