NOAA confirms record-breaking hailstone in South Dakota
A hailstone that fell from a severe thunderstorm in South Dakota has been officially declared the largest ever recorded in the United States, in terms of both diameter and weight, according to the NOAA National Climate Extremes Committee. The stone was 8 inches in diameter, 18.62 inches in circumference and weighed 1 pound, 15 ounces. This is just short of the size of a soccer ball. The record-breaking hailstone fell in Vivian, South Dakota. It was found by Les Scott, who immediately took action to preserve it. "Mr. Scott told me the area was littered with large hailstones and the largest had a greater diameter when he first found it," said David Hintz, warning coordination meteorologist at the Aberdeen, South Dakota, weather forecast office. "He immediately stored it and several others in his freezer, but a power outage caused some melting."
The weather office in Aberdeen notified regional weather authorities, who then requested activation of the National Climate Extremes Committee to evaluate the massive hailstone. Official measurements were submitted to the committee of three, which then certified that the hailstone was a record-breaker. The previous record-holding hailstone in the weight category fell in Coffeyville, Kansas, in 1970 and weighed 1.67 pounds. The previous record-holding hailstone in the diameter category fell in Aurora, Nebraska. It measured 7 inches across. This stone -- at 18.75 inches -- still holds the hailstone record for circumference.

Hail yes, it's big: Colo. lab gets record hailstone
This hailstone was found by a ranch hand in Vivian, S.D., on July 23, 2010. At 1 pound, 15 ounces it is believed to be the heaviest ever to have fallen in North America.
North America's heaviest hailstone ever might also be its most-traveled. A 1-pound, 15-ounce hailstone that fell in Vivian, S.D., in July has been taken to National Center for Atmospheric Research in Boulder, Colo., about 370 miles away. Researchers there say they plan to study the giant stone. It's not clear what tests will be done, but the lab isn't taking any chances. A tweet announcing the hailstone's arrival said, "Hey, keep that away from the margarita mix!" The hailstone fell on July 23. Last Friday, federal climate officials confirmed it was the heaviest ever recorded on the continent.
