Ice cover remains at or near historic low coverage with Great Lakes total ice cover at 4.9% today (compared to data going back to 1973). In Lake Superior there is some fast ice in Keweenaw Bay, with some limited ice along the southern shore in the eastern basin, including St. Marys River and the Soo Locks, although analysis suggests no fast ice until you get farther downstream into Lake Huron (e.g. Lake Nicolet and Munuscong Lake). Elsewhere in Lake Huron, there is some limited ice in western Lake Huron near Mackinac with fast ice in Saint Martin Bay, and some limited ice in Saginaw Bay. In Lake Michigan, there is some fast ice along the shorelines west of Mackinac, including Sturgeon Bay. There is some limited ice in all of Green Bay with some fast ice in Little/Big Bay De Noc. Lake Erie is ice-free. Above normal temperatures are expected as a warm front lifts northeast across the Great Lakes tonight. This will result in slight ice decay through Tuesday. A cold moves across the Great Lakes region Tuesday night and Wednesday, resulting in gales and decreasing temperatures to well below freezing. Regarding the gales, the is a Gale Warning for Lake Superior and Gale Watches for Lake Michigan and Lake Huron. Any ice on the lake will shift to the southeast. The cold temperatures will likely lead to moderate ice growth in the northern half, and slow growth in the southern half of the Great Lakes Wednesday through Thursday morning. Temperatures warm back up to well above normal on Friday, with ice decay expected on Friday and through the weekend.
