Great Lakes Ice Increasing Relatively Rapidly

As of Monday PM, the Great Lakes had a 19.7% ice cover.

  This is a pic. from the Muskegon Channel Monday PM – it was snowing, but you can also see ice as far as you want to look.  I certainly wouldn’t try and walk out on it, especially at a river outlet where the water is moving under the ice, but that’s a lot of ice for Jan. 1.  The high temperature at the Muskegon Channel on Monday was 16.0°

  This is the South Haven Channel – with floating “pancake” ice reaching well out past the lighthouse.  The high temp. Monday PM at the S. Haven Channel was 16.2°.

  This was Chicago on Monday…sunny on the other side of Lake Michigan.  You can see lots of “crushed ice” floating in the water.  The high temp. here at the Chicago water intake on Monday was only 5.0°.  O’Hare Airport had a high temp. of +1 on Monday and that was 31 deg. colder than average!  Farther west, Storm Lake and Sheldon IA had high temperatures Monday of -9°.

This is Alpena MI, where there is ice as far as you can see out into Lake Huron.

Great Lakes total ice cover is approx. 20%.  Lake Michigan was at 19.2% Mon. PM, Lake Huron at 30.7%, Lake Erie at 39.5%, Lake Ontario at 15.9% and Lake Superior at 7.7% (a lower figure because the lake is much deeper than the other Great Lakes (the deeper the lake, the longer it will take to freeze over in winter).  Lake St. Clair is 99% frozen over as the Coast Guard tries to keep a channel open for ships.  Arctic air holds firm the rest of this week…so those numbers will increase.
