The National Weather Service has not yet confirmed reports of a tornado touching down in Chico, Calif. around 2 p.m. PT Tuesday.
"The set-up for thunderstorms and tornadoes is ideal across California tonight. The storm coming across California is the coldest of the season and contains plenty of cold air aloft which will support the formation of thunderstorms," AccuWeather.com Expert Meteorologist Bernie Rayno said.
"The twisting and turning around the upper low provides the spinning in the atmosphere that produces the funnel clouds that produces the tornadoes," Rayno said.
Tornadoes in California are generally short lived and weak.
There have not yet been any reports of damage or injury.
