Snow, Rain Storms On Tap For Bay Area

SAN FRANCISCO BAY AREA, CA — Winter has returned to the Bay Area, bringing scattered rain and snow showers Friday, with another round of precipitation forecast to arrive Sunday. By midweek, there is potential for an atmospheric river, according to the National Weather Service.

The weather conditions Friday include isolated to scattered rain showers and cooler temperatures, with isolated thunderstorms possible Friday afternoon.

Mostly dry conditions are expected Saturday in the Bay Area before another weather system brings more widespread rainfall Sunday into Monday.

"This system will be accompanied by a much colder air mass with lowering snow levels Sunday night into Monday, bring snow showers to the region's ridges and peaks," the National Weather Service said.

While only lingering showers will be possible on Monday, the weather service expects a more potent weather system to arrive by midweek in the form of a weak-to-potentially moderate atmospheric river.

"This will increase the threat of nuisance type flooding in lower-lying, poorly drained areas and could potentially trigger debris flows in recent burn areas," the weather service said.

But the rainfall has brought respite for Cal Fire San Mateo-Santa Cruz County firefighters who've battled 18 wildfires across the region in recent days.
