Just before this, I happened to be chasing a cell off to the NW near Ogallala, NE when the storm crossed into a terrible road network. Once I saw the McCook storm was strengthening and wrapping up on radar, I drove toward Cozad and headed south. I had made it just in time to catch this tornado for its last 5 minutes on the ground. The poor image quality can be blamed on me due to my lack of gear. This was taken with an iPhone.
