A cold front will be dropping in across the area during the day on Sunday. Showers and a few thunderstorms are expected to accompany this cold front through the area. Below is a map of the front and its forecasted location at 2 pm Sunday.
The front, combined with below average temperatures around 5,000 feet above the surface of the earth, and the relatively warm waters of Lake Michigan, are expected to create a potential of a few waterspouts over Lake Michigan on Sunday. The potential will not be quite as high on Monday, but it still may be possible as one more front drops down through the region. See the image below for the locations of fronts Monday morning.
