Lake Michigan Ice IncreasingFebruary 27th, 2014 at 12:45 am by Bill Steffen under Bill's Blog, Weather
Click on the images to enlarge. The picture on the left is the MODIS satellite picture from Weds. PM. Note the ice that has reformed east of Wisconsin and Illinois. You can see where the lake-effect clouds are forming, fairly close to the Michigan shore. It’s sunny in SE Wisconsin and NE Illinois. You can see some high clouds crossing central and northern Lake Michigan. Now look at the picture on the right, taken at the Grand Haven beach at sunset just a couple hours after . You can see the sun shining underneath the lake-effect clouds. The graph in the middle is the record of the percent of ice cover on Lake Michigan this winter (from NOAA/COASTWATCH). It’s not a steady climb, it’s a “jerky” graph. Ice forms on the lake and then strong winds break it apart. The strong winds of last Friday broke up most of the ice on Lake Michigan, a truly extraordinary event to see the ice cover on the lake go from around 80% all the way down to 30% and now back up above 50%. With the cold that’s coming over the next week, we could very well see the ice cover get back to 70-80% coverage! Here’s current total Great Lakes ice coverage (77.3% as I write this). Specific Great Lakes ice coverage for 2/26: Superior 94.4%, Michigan 52.0%, Huron 92.8%, Erie 93.9%, Ontario 11.3%.
