Crazy Storm Clouds Formed In South Dakota

Some people would turn and run when they came upon an absolutely evil-looking storm cloud formation, but not storm chasers Chad Cowan and Jenna Blum.

They shot the video of this storm in South Dakota on July 23rd. They write on their YouTube page that earlier in the day the storm dropped a record piece of hail: 8 inches in diameter and weighing almost two pounds.
