CHICAGO — Chicagoans along the city’s lake shore spotted funnel clouds over Lake Michigan Wednesday afternoon as around a dozen waterspouts formed in the area, according to Tom Skilling.

The funnel clouds typically form over the lake when thunderstorms combine with strong, cold northeast winds rushing over its warm surface.

While they’re typically smaller, weaker, and considered to be less dangerous than land tornadoes, experts warn waterspouts can still overturn boats or do damage if they hit land. More are possible this week, Skilling said.

Viewer Randall Stieghorst captured the mesmerizing phenomenon on video as the sinking cold air combined with the relatively warm waters of southern Lake Michigan, swirling into a waterspout.
