5 Day Ice Discussion...

Ice coverage continues to be limited across the Great Lakes with
only a few of the bays and harbors reporting any coverage. Ice cover
was observed on Lake Superior in Chequamegon Bay, near the Apostle
Islands, on Lake Michigan in Green Bay, on Lake Huron in Saginaw Bay, and
on Lake Erie across Sandusky Bay.

Weak storm systems will continue to move across the Great Lakes
through mid week. The strongest arriving Wednesday night into
Thursday across the Upper Great Lakes. This storm system will move
eastward across Ontario into Quebec with colder air arriving in its
wake on Thursday into Friday. All of these storm systems will assist
with keeping wind speeds of 15 to 20 knots or higher through the
week. This limit the ice growth until colder air arrives Thursday
into Friday. Expect the best ice growth to occur across the Upper
Great Lakes Thursday night into Friday as high pressure begins to
move overhead and decreases wind speeds.
