Ice coverage remains well below normal for January but the coldest air of the season will arrive over the weekend and persist into early next week. Ice coverage so far is confined to the northern and southern tip of Green Bay. Arctic air will become firmly established across nearly the whole region by Sunday and remains through Wednesday, when only some minimal warming will occur. This will lead to rapid ice growth on the upper lakes and ice growth beginning on Lake Erie. The ice growth will be prevalent on both the Green Bay and Saginaw Bay. Ice is also expected to form along the south shore of Lake Superior, including Superior Bay, Chequamegon Bay, the Keeweenaw Bay, and some growth in Whitefish Bay. Some growth is possible on the far northern shores of Lake Michigan and Lake Huron. Ice may also start to form on Lake Erie west of the Islands. Winds will be strong tonight through Saturday as deep low pressure tracks northeast through the Central Great Lakes. Storm Warnings are currently in effect on Lake Superior, norther Lake Michigan and northern Lake Huron. A Storm Warning also goes into effect on the east half of Lake Erie at 9 AM Saturday. Gale Warnings are in effect for the remainder of the Great Lakes and some will continue into Sunday for portions of the region. A Heavy Freezing Spray Warning is also in effect on Lake Superior through Saturday.
