Cellphone video posted online showed a towering vortex spinning Saturday evening near Davis.
National Weather Service forecaster Emily Heller told the San Francisco Chronicle that there was no damage.
Just north of Davis yesterday. More thunderstorms are expected this afternoon/evening. Stay alert to changing conditions. https://t.co/g5yLEjL3mM

Tornadoes in the state aren’t entirely unusual and are “weaker and more short-lived” than ones typically seen in the Midwest, she said.
“Tornado outside Davis. Totally terrified me. I was heading back to Davis from Woodland,” wrote Twitter user @ thedreadedheidi.
Sierra Peaks Could See 6 Inches of Snow
Saturday’s storm blanketed some roadways with hail in and around Solano County. To the east, forecasters issued a winter weather advisory after several inches of snow fell in the Sierra Nevada.
Heller called it “the first real snow of the season.”
Elevations of 6,000 feet and above recorded up to 4 inches of fresh powder Saturday. More snow was forecast for Sunday into Monday and the highest mountain peaks could see up to 6 inches.
The severe weather is the result of a cold front over the Pacific Northwest that is spinning out waves of unstable air as it moves east, Heller told the newspaper.
