Ice coverage across the Great Lakes region remains at a historical low with a total coverage of 3.8%. This is the lowest for the end of February since 1973 and well below the historical average, which is around 40%. Much of the ice coverage in the region remains on the Canadian side of the Great Lakes. However, there are still some locations in the American waters of the Great Lakes that has notable ice. For Lake Superior, there is ice in the southwest waters near the Apostle Islands and Chequamegon Bay and the southeast waters near Whitefish Bay. On Lake Michigan, there is ice in Green Bay, the Bays de Noc, and the far northern portion of the lake toward the Strait of Mackinac. Lake Huron has limited ice coverage in the American waters with ice just in the St. Mary's River, the northern portion of the lake near the Strait of Mackinac, and some limited ice in Saginaw Bay. Lake St. Clair and Lake Erie are mainly ice free. Thursday appears to be the only productive ice growth day across the region with a cold air mass in place behind a strong cold front and winds lessening through the region. High pressure will enter the region from the south on Friday and a warm front will move through the region on Friday night into Saturday. Ice growth will slow with moderating temperatures on Friday and above normal temperatures will spread across the entire region on Saturday to help diminish ice. These well above normal temperatures will continue across the region into early next week and will keep ice coverage in the region at historically low levels.
