On this date back in 1970, severe thunderstorms hammered Southeast Kansas with hail that reached epic diameters of 4 to nearly 6 inches. Coffeyville, Kansas was bombarded by a hailstone that measured 17.5 inches in circumference, 5.7 inches in diameter and weighed 1.67 pounds. It had been the largest hailstone on record in the United States until June 22, 2003, when Aurora, Nebraska was hammered by a specimen measuring 18.75 inches in circumference and 7 inches in diameter.
However, the Aurora event did not 'hail' as king of hailstones very long. On July 23, 2010, an even bigger hailstone 8 inches in diameter and weighing 1.94 pounds landed in Vivian, South Dakota
