5 Day Ice Discussion...

Ice coverage in the American waters of lakes Superior, Michigan, and
Huron remains below normal for this time of year, but ice coverage on
Lake Erie is well above normal at around 95 percent. Fast ice is present
along the immediate lakeshore of Lake Erie with significant breaks in ice
along the Michigan lakeshore and between roughly the Islands and
Vermilion, OH. Ice is present along the lakeshore of Lake Huron with the
highest concentrations from roughly Thunder Bay south to the St. Clair
River. Fast ice is present over Saginaw Bay. Ice is present in the
nearshore waters of Lake Michigan, although the open waters remain ice-
free. Fast ice is present on Green Bay and the northern tip of Lake
Michigan in addition to the Straits of Mackinac. Ice coverage on Lake
Superior is largely confined to waters along the lakeshore, although fast
ice is present around the Apostle Islands and in Chequamegon Bay and
Whitefish Bay. Overall ice coverage for the Great Lakes (including Lake
Ontario) is currently about 38 percent.

Temperatures will remain below freezing across the majority of the Great
Lakes through Friday with temperatures beginning to warm over the weekend.
As a result, slow to moderate ice growth will likely continue before
starting to slow as temperatures begin to warm over the weekend. Winds
will generally be 25 knots or less through Friday night so the risk of
significant shifts in ice remains low.
