5 Day Ice Discussion...

Ice on the Great Lakes remains primarily confined to the shallow bays and
channels of lakes Superior, Michigan, and Huron. Otherwise, the vast
majority of the Great Lakes remains ice free.

A brief period of cooler weather is expected across the northern Great
Lakes through mid to late week, which may result in slow to moderate ice
growth. However, the higher March sun angle in addition to breezy winds
may inhibit ice growth. The lower Great Lakes will remain ice free with
above freezing temperatures expected through the majority of this week.
