Rain could help quench the last of the fires still burning in Sonoma, Napa and Mendocino counties, while snow is likely fall in the Sierra.
Redwood Valley is expected to receive 0.38 inches of rain Thursday afternoon and evening, according to the National Weather Service, while the Santa Rosa area will get a quarter-inch to a half-inch.
The Nuns and Tubbs Fires, which have burned more than 90,000 acres combined, are both at least 80 percent contained and could be fully extinguished with the right amount of rainfall, said Brian Mejia, a weather service meteorologist in the Bay Area, as could the 85-percent contained Redwood Valley Fire.
“It’ll definitely help. As far as the extent of how much it’ll help, we’re still unsure because it really depends on the exact amount that falls,” Mejia said Thursday morning. “But hopefully we can contain them and put them out entirely.”
Three to six inches of snow are predicted above 6,500 feet elevation in the Sierra as a low-pressure system from the Gulf of Alaska heads south. Winds in the North Bay and lower Sacramento Valley are expected to hover between 10 mph to 15 mph with a occasional 20-mph gust.
About 0.12 inches of rain is anticipated to drop over Sacramento between 5 and 11 p.m. Thursday, with some parts of the valley getting up to 0.3 inches, according to the weather service. It will then likely remain dry through the weekend and into next week, with highs rising from 66 degrees on Friday to 85 degrees Tuesday.
