*************************************

Unbelievable! I would give a significant and important body part to have been there to get video of that coming down. However, I can only guess that would have been terrifying!! I have personally witnessed cantaloupe size hail, and that was pretty scary, but to imagine hail coming down that would make those kind of craters. I wonder what livestock, if any, was killed around there by that? What is really incredible is when you have to think about the vertical wind speeds in the updraft of that storm capable of suspending hail until it reached that size! What an intense storm!

EDIT UPDATE:

The largest hailstone (pictured below) documented in Dante was officially measured by Dr. Todey at 6 and 7/8 inches in diameter, with a circumference of 18.00 inches and a weight of 1.0 pound, which does set a new record for the state of South Dakota. The previous South Dakota hailstone record was 6.00 inches in Custer County on June 22 1968. Records for hail in South Dakota date back to 1950.Nationally, the largest hailstone on record (based on diameter and circumference) occurred at Aurora, Nebraska, on June 22, 2003. The 2003 Aurora hailstone measured 7 inches in diameter, and had a circumference of 18.75 inches. The Dante hailstone fell just short of this, coming in 1/8 inch shorter, and 3/4 inch smaller in circumference.
