5 Day Ice Discussion...
Overall ice coverage across Lakes Superior, Michigan, and Huron
is below normal for mid February. Ice coverage on Lake Erie
continues to be well above normal as ice coverage remains between 85-
95%. A mix of medium to thick lake ice is present across the Straits
of Mackinac, Green Bay, and Saginaw Bay with generally new to thin
lake ice present along shorelines. Current ice coverage across all
Great Lakes is roughly 26 percent.
Much of the region should remain below freezing through this week
with a cooler air mass approaching the northern Great Lakes by mid-
week. Multiple systems will enter the Ohio Valley region from the Great
Plains through this week which will keep the colder air mass well north of
the southern Great Lakes. Moderate ice coverage growth is expected
through this week.
