It could be one for the record books in Colorado. A few supercell thunderstorms developed in eastern Colorado on Tuesday. They produced a few tornadoes and some very large hail and I mean LARGE hail. There was a report at 4:35 PM of 5.0″ diameter size hail in Bethune, CO. It was officially measured at 4.83″. That is bigger than a softball. The map below shows where Bethune is in relation to Denver.

If this hail stone is verified, then this would be the largest hail stone ever recorded in Colorado.
This would not be the largest ever recorded in the U.S.. The U.S. record is 8″ and that was in South Dakota. You can read more about that by clicking here on a previous blog post.
The unofficial largest hailstone in Iowa was in Dubuque and reported to be 5.5″ in diameter on June 16, 1882.
