Sunday's storm system brought a big surprise to people in Dos Palos.
Many spotted a funnel cloud.
The funnel cloud was actually about six miles northwest of Chowchilla.
KMPH Fox 26's Jim De La Vega says this was not a tornado, but rather a "cold air funnel."
The base was about a thousand feet off the ground.
"It did not have a lot of strong rotation," says De La Vega.
He says the funnel cloud was moving at about ten miles an hour.
