Lake Superior is up a whopping 9″ in the last month and 13″ in the last year. Superior is now a full 7″ above the long-term average.

Did you see the video of the fog coming in off Lake Michigan Wednesday?? The temperature in Holland (airport) dropped 15° in an hour as the fog and cool air moved inland.
