5 Day Ice Discussion...

Overall ice coverage across Lakes Superior, Michigan, and Huron continues
to be slightly below normal for mid February. Ice coverage on Lake Erie continues
to be well above normal as ice coverage is around 90 to 95%. The latest SAR
imagery reveals the remaining 5 to 10% of "ice-free" area for Lake Erie
residing on the northern shores of Ontario towards The Islands, resulting
from strong westerly winds Thursday evening. A mix of medium to thick
lake ice is present across the Straits of Mackinac, Green Bay, Saginaw
Bay, and most recently, the eastern shoreline of Lake Erie. New to thin
lake continues to appear and increase in coverage along the shorelines of
all other Lakes. Current ice coverage across all Great Lakes is roughly
33 percent.

The entire Great Lakes region is expected to remain below freezing through
the weekend and into early next week. Modest north to northwest winds of
20 to 30 knots will return across much of the Great Lakes behind a
deepening low pressure system Sunday into Monday which could contribute to
significant shifts in the ice. Arctic air will arrive behind this system
which could lead to areas of moderate to rapid ice growth, particularly
across the Upper Great Lakes.
