Watch This Beautiful Video of a Supercell Storm near Tilford, SD

Fellow weather geeks check this out. Dan McKemy made this time-lapse video of a supercell thunderstorm in western South Dakota recently. McKemy says that the storm formed in the late afternoon near Tilford, SD, which is near Sturgis, and moved southeast where there were reports of large hail.

You can clearly see the storm's rotation and the area of rain in the middle. On their Facebook page, The National Weather Service office in Sioux Falls notes that this is a good example of a storm with lots of rotation that never produced a tornado.

It's a beautiful video, watch.
