Large hail fell across portions of southeast South Dakota Tuesday evening August 21, 2007. The small community of Dante, in southeast Charles Mix County, took a direct hit from the large hail. Most homes in Dante sustained considerable hail damage, with holes punched in almost every roof in town by the large hail.
The National Weather Service surveyed the damage on Wednesday, August 22, and the largest hailstone found on Wednesday was measured to be 5.25 inches in diameter. This hailstone was not picked up for 10 to 20 minutes after it fell, so it was likely larger when it hit the ground. The large hail created craters up to 10 inches by 12 inches in the yards throughout Dante. The largest hail fell at approximately 610 pm on August 21 2007.

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.

Another very large hailstone was also documented in Dante on Thursday. This hailstone (pictured below) measured 6 and 1/8 inches in diameter, with a circumference of 15.5 inches, although it was heavier with a weight of 1.25 pounds. The heaviest hailstone on record in the United States fell in Coffeyville, Kansas, on September 3, 1970. That stone weighed 1.65 pounds, still over 1/4 to 1/2 pound heavier than the Dante hailstones we recorded.
