Ice coverage across the Great Lakes remains below normal, with strong winds and gusts earlier this week leading to some movement of thin lake ice. Areas of new to thin lake ice exist along the southern shores of Lake Superior with medium lake ice across the Chequamegon Bay. Similarly, new lake ice can be seen across the Straits of Mackinac and along the Wisconsin and Illinois shoreline of Lake Michigan with thin and medium lake ice across Green Bay. Generally new and thin lake ice is present across Thunder and Saginaw Bay in Lake Huron and across the western basin and southern shores of Lake Erie. A persistent cold air mass with below freezing temperatures will allow for moderate ice growth through this week. Minimum temperatures will drop below zero across the western Great Lakes which may bring a period of rapid ice formation this weekend.
