An all to rare super cell thunderstorm traveling across Palisades Lake and the Snake River Range of eastern Idaho. Upon a take cover weather alert, I jumped in my car to get to the west side of the storm as it was early evening and a great recipe for a great rainbow shot ( got a double rainbow also ). After reaching the western edge I followed it east. Because of the hail, sane people were pulled over to the side of the road. It was a fruitful storm.
