Ice coverage across the Great Lakes remains below normal for mid January despite a period of below freezing temperatures. Ice concentration has decreased slightly across all lakes over the past few days. However, ice persists across the southern shores of Lake Superior, including Chequamegon and Keweenaw Bays, and Lake Michigan across Green Bay with decreased ice concentration along the Michigan and Illinois shoreline. Moving east to Lakes Huron and Erie, ice remains along Thunder Bay with some fast ice on Saginaw Bay and continued ice across Maumee Bay on Lake Erie. A period of strong westerly winds greater than 25 knots through the middle of this week may lead to some movement of thin ice across the lakes before winds diminish. Continued below normal temperatures with lows below freezing will persist through this week which will allow for slow to moderate ice growth.
