Extreme Weather Causes Snow Rollers Throughout The Midwest

Snow rollers are being spotted in open fields throughout the Midwest. The unique snowballs and rolls are rare as they require a specific combination of conditions to form. Extreme cold and high winds throughout the region have provided the perfect environment for the rare formations.

The naturally occurring snow balls form where ice or ice-encrusted snow exists in a uniform layer over the ground. The surface layer serves as a platform where the balls are formed and can easily travel. The second layer, which rests on top of the ice, must be wet snow that is fluffy and loosely packed. This condition can be difficult to meet as wet snow is often quite dense.
