In 1970, a record hailstone fell on Coffeyville, Kansas, the heaviest authenticated one to fall in the U.S. in the 20th century. Its weight was recorded as 1-lb 11-oz (0.77 kg) with 5.7-in (14.7 cm) diam. It broke the old record from 6 Jul 1928 at Potter, Nebraska, for one weighing about 1-lb 8-oz (0.68 kg), around 7-in diam. A newer U.S. record for size was set on 22 Jun 2003 in Aurora, Nebraska, when a hailstone was found about 7-in diam. (17.8 cm) and 18.75-in (46.6 cm) circumference. The world record was broken on 23 Jul 2010, by a hailstone found in Vivian, South Dakota at 1-lb 15-oz, (0.88 kg), 8.0-in (20 cm) diam., 18.6-in (47.3 cm) circumference. A larger hailstone is said to have fallen on 14 Apr 1986 that weighed 2-lb 4-oz (1.02 kg) during a hailstorm in Bangladesh that killed 92 people.«
