Lake Michigan's Ice Coverage: January 2014
The long period of extreme cold this winter has produced a higher than average amount of ice on the lakes, especially Lake Michigan. Lake Michigan has almost iced over quite a few times in the last 50 years. The last time being almost 20 years ago in February 1994.
This year, according to the National Oceanic and Atmospheric Administration's Great Lakes Coastal Forecasting System, the ice has already taken over a little more than 43% of the lake, which is above the long-term average. With just a little over a month of winter to go, if the extreme cold persists, the accumulation of ice in the lake will definitely increase.
