This is a collection of footage from a storm chase in southeast Iowa on June 20th 2015. There was a brief rain wrapped tornado near Eddyville IA that isn't quite visible on the video despite the camera pointing directly at it. This line of storms was moving very fast at nearly 60mph. It was hard to stay ahead of it. Eventually, I had to give up and let it overtake me. An intense rotating wall cloud persisted for at least an hour, and eventually produced the tornado near Eddyville.
