One other atmospheric river enters the San Francisco Bay Space forecast
The rain just keeps coming.
The second weak storm of the week will sweep the San Francisco Bay Area on Wednesday; During the night from Thursday to Friday, another system can bring light showers to the north bay.
A rain break is expected for the weekend, but the drought will not last long. Long-term weather models show that a weak atmospheric river dips into the region and brings soaked rain from Monday to Tuesday.
This is good news for the San Francisco Bay Area, which along with the rest of California is facing dire drought conditions after two consecutive dry winters. This year, the rainy season started on October 1st and is already promising as the region is seeing above average rainfall for the month.
“We’re taking it,” said Drew Peterson, a meteorologist with the Bay Area Meteorological Service office. “California is a festival or hunger state. We tend to swing back and forth. We’re often way below or way above, and it’s hard to get that average rainfall.”
A thick blanket of fog hung on the San Francisco Bay Area on Wednesday morning, hampering driving conditions across the region. The weather service issued a thick fog warning for the North Bay Coast, San Francisco and the San Francisco Peninsula coast earlier this morning, warning of a quarter mile or less of road visibility. “Use your low beam and keep a safe distance,” warned the weather service. The fog is supposed to clear after 9 a.m.
Wednesday mornings and afternoons are dry and mild with cloud cover increasing in the late afternoon and evening. A cold front from the north will fall into the North Bay between 8 p.m. and 10 p.m. and move through the central Bay Area around midnight.
Peterson described the system as weak. The weather service forecast total rainfall of 0.5 to 1.5 inches for the coast of Sonoma County, up to 0.5 inches for the Sonoma Valley, up to 0.25 inches over the San Francisco Peninsula and into the Santa Cruz Mountains and less than 0.1 inches in South Bay, East Bay and along the central coast.
“It will definitely weaken and taper as it pulls in,” said Peterson. “We have a lot of pressure downstream and when we have that it weakens these systems.”
The showers could last through Thursday morning, resulting in a cool Thursday afternoon and dry and cold conditions on Friday.
A weak system moving across distant Northern California could cut off North Bay on Friday, delivering drizzle and light rain. The central Bay Area is expected to remain dry.
The weather service said long-term models tend to be a dry weekend with a wet storm approaching the region from Monday night to Tuesday. The weather service described the storm in its forecast as a weak atmospheric flow. Preliminary storm totals show the storm will bring 1-plus inch of rain to the area, but it’s still too far away to pinpoint.
“I see we have heavier rainfall earlier this week,” said Peterson. “It’s still on the right track. I wouldn’t say it’s a slam dunk at this point. But given the progressive weather this season, I’d say the odds are higher. Often times these systems roll in and will.” blocked by. ” a big high pressure comb, and we don’t have that. And that’s what I mean by progressing. The storms keep coming. ”
