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.
