Temperatures in parts of the North Bay are expected to reach 90 degrees today and afternoon thunderstorms are anticipated, according to weather service meteorologist Dan Gudgel.
"We think we might have the conditions that could lead to some afternoon thunderstorms, but we don't necessarily think it's imminent," Gudgel said.
The fire weather watch is expected to remain in effect until 6 a.m. Saturday, according to Gudgel.
Dry lighting has sparked at least 1,000 wildfires in California in the past month that collectively have burned at least 265,000 acres, according to Gov. Arnold Schwarzenegger.
The governor requested money today from the federal government to help fight the fires, burning mainly in Monterey, Santa Clara, Santa Cruz, Shasta, Trinity, Mendocino and Butte counties.
