5 Day Ice Discussion...

The recent milder weather pattern has slowed down ice formation as well as
a decrease in coverage on the Great Lakes over the past few days. The
latest ice analysis indicates that Green Bay, Saginaw Bay, and the Straits
of Mackinac is partially to mostly ice covered. The western basin of Lake
Erie around the islands and Sandusky Bay has some limited ice cover. Lake
St Clair has lost most of its ice cover recently. There remains some
limited ice cover along the southern shores of Lake Superior at this time.

The weather pattern will continue to be milder than average through
Tuesday before a series of Arctic fronts moves across the Great Lakes
region mid week through this upcoming weekend. The weather system Tuesday
through Wednesday will bring strong gusty winds, starting out from the
southerly direction followed northerly to northwesterly flow. The shifting
wind flow will likely shift some of the weaker ice around on the Great
Lakes. The general forecast trend mid week through this weekend will favor
much colder temperatures and the potential for ice growth on much of the
Great Lakes.
