Bay Area residents will have to keep scraping frost off their car windshields — but warmer weather isn’t too far off. Temperatures are expected to rise into the 60s by the weekend.

A freeze and frost warning is in effect until Friday morning for the Bay Area and Central Coast, according to the National Weather Service. The biggest risks include hypothermia for people without adequate shelter, including people and animals. Sensitive vegetation and crops might also die off during the freeze and outdoor plumbing could be damaged.

Thursday morning, it reached 27 degrees in Santa Rosa, 33 degrees in San Jose, 41 degrees in San Francisco and 34 degrees at the Oakland International Airport. The coldest spots were interior locations of Monterey and San Benito counties, with temperatures dipping into the 10s.

“They get influence off of the oceans,” said forecaster Matt Mehle. “Coastal areas near the Bay shoreline tend to be warmer, as opposed to Santa Rosa and Napa that are further inland, it’ll be colder.”

With temperatures predicted to be far above normal in much of Southern California, the National Weather Service upgraded a heat watch to a heat advisory lasting from late Wednesday morning through Sunday.

Fire Marshal and Public Information Officer for the Santa Rosa Fire Department.

Santa Rosa resident Rebecca Ryan looks down Tachevah Drive and remembers when her street flooded during the last heavy rainfall.

Sonoma County ranchers, water managers welcome rain but caution that California drought persists

in Weather

West Sonoma County livestock rancher Joe Pozzi loves the bright green grass sprouting on the 1,200 acres he grazes sheep and cattle in the wake of two unseasonably large storms since the water year began last month.

They dropped more water on the region in a span of three weeks than all rainfall recorded at the county airport over the past year — the second in a severe statewide drought.

Santa Rosa at 176% of normal rainfall for this time of year

in Weather

The National Weather Service released a model simulation on Twitter Wednesday night showing how the next storm will move across the San Francisco Bay Area Thursday to Friday. The weather service said the storm is expected to bring beneficial rain.

The storm will arrive Thursday night and deliver widespread light rain with brief spells of moderate rainfall.

“Rainfall will be heaviest over North Bay,” NWS meteorologist Matt Mehle said. “Areas that didn’t see rain on the last one will likely see rain with this one, such as parts of the East Bay like Livermore, parts of Santa Clara Valley.”

The Thursday-Friday storm could bring an additional 1 to 3 inches in North Bay mountains, with amounts tapering down to around 0.75 inch in the region’s valleys.

Much-needed rain finally falling in the Bay Area

in News

Light rain started falling Sunday evening in the Bay Area, as a week of much-needed precipitation was forecast for the parched Northern California landscape.

One to 2 inches of rain is expected to fall across the Bay Area over the next week, and even more could fall across the North Bay as a series of storms dives in from the northwest, said Rick Canepa, meteorologist with the National Weather Service. To the east, parts of the Sierra Nevada could see more than a half-foot of snow by Monday morning.

The upcoming storms could equal or surpass average monthly rainfall totals in just a matter of days — a welcome prospect for the region, Canepa said.

National Weather Service: North Bay mountains could see damaging winds

in News

The National Weather Service on Sunday upgraded its wind advisory to a high wind warning for higher elevations, alerting residents across a vast swath of Central and Northern California to the potential for ferocious, damaging winds starting Monday afternoon.

The warning, which takes effect at 4 p.m. Monday and applies to areas at elevations 1,000 feet or higher, cites the potential for winds reaching 60-70 mph at a variety of locations from Big Sur to the North Bay mountains. Winds were already expected to pick up at all elevations Sunday night, leading the National Weather Service to issue a rare winter fire weather watch for large swaths of Central California.

“The wind will be just as strong up in the North Bay as what we’re expecting in Central California,” said Duane Dykema, a National Weather Service meteorologist. “Because there’s been more rain in the North Bay, the fire danger isn’t as high.”

Dykema said the Santa Cruz mountains mark the northernmost area of concern in terms of fire danger, but he urged resident caution due to expected high winds in the North Bay.

The buildup of smoky air in North Bay communities since Sunday represented yet another health threat for local residents, but for firefighters, it signaled the persistence of calmer conditions that have allowed crews to gain ground on week-old wildfires.

The dropoff in wind in the hills, however, has led to smoke accumulation in more settled valleys across Sonoma County and the greater Bay Area, posing a threat to children or residents with health risks, especially if they’re outside for a prolonged period or choose to exercise in the open.

Th air quality index rose as high as 152 on Monday, well above the 100 federal health standard for healthy air, according to the Bay Area Air Quality Management District. A Spare the Air alert remains in effect through Wednesday, banning any wood-burning or fires both inside and outdoors.
