NASA: Ice Coverage on Lake Superior
Written by N.A.S.A.
Below normal temperatures in December and January have resulted in significant ice cover developing on Lake Superior. This false color satellite image allows for easier identification of ice and open water. The aqua colored areas on Lake Superior indicate ice cover, black areas indicate open water, and white areas indicate cloud cover. Bands of lake effect snow are evident forming over the open waters of eastern Lake Superior.

Although there are scattered snow showers over parts of western Lake Superior, cloud cover is significantly less than over eastern Lake Superior. This provides an indication of how the ice cover is working to limit the development of lake effect snow showers. This image was taken on February 4th.
