Video from Jefferson County shows a roof that appears to be at least partially torn from a home due to severe winds.

In West Allis, tornado sirens blared as the storm moved through overnight, waking many residents, though the storms themselves may have accomplished that, too.

A tree was seen down near 20th and Greenfield in Milwaukee, having landed on top of several cars.

We spoke to a man early Tuesday who says his car was damaged after he drove into a fallen tree. He said, "While I was driving, it was raining -- downpouring. It was dark outside. Couldn't really see nothing. Came up on the tree, last minute."
