During the afternoon of November 15, 2006, an unusual cloud formation was seen across central Wisconsin.  Known as "hole punch clouds,"  the holes develop as ice crystals above the main cloud layer fall through the clouds, causing the super-cooled water droplets to evaporate.  The result is a circular form void of clouds, with a mass of crystals in the center.    The photo was taken by Samantha Weise in Stevens Point.
