Michigan is most impacted by lake-effect snow due to its proximity to the Great Lakes.

Michigan is heavily impacted by lake-effect snow because of its proximity to the Great Lakes, particularly Lake Michigan and Lake Superior. This weather phenomenon occurs when cold air moves over the relatively warmer lake waters, causing the air to pick up moisture. As the air moves over the cooler land, this moisture is released in the form of snow, leading to heavy snowfall, especially in the downwind areas. Michigan, especially its western and northern parts, experiences significant lake-effect snow each winter, contributing to the state’s snowy, cold winters. This weather pattern is a key feature of Michigan's climate.
