It depends on whether you measure diameter or circumference. The largest circumference was in a hailstone that fell near Aurora, Nebraska on June 22, 2003. It was 18.75 inches in circumference and 7 inches in diameter. The largest diameter was recorded near Vivian, South Dakota on July 23, 2010. The hailstone was 8 inches in diameter and 18.625 inches in circumference. The official record goes to the Vivian hailstone. This difference has to do with the fact that the largest hailstones are often lopsided.
It depends on how strong the updrafts in a thunderstorm are. The stronger these updrafts (winds), the larger the hailstone it can support. As long as the hail remains supported in the cloud, it will continue to accrete ice and grow larger.
the hailstone starts as snow, an updraft of warm air and a downdraft of old air causes the hailstone to form. it falls to the ground
it would fall at a lighter speed
