Hail Formation
qFormed as graupel is carried aloft in updrafts
qAt high altitudes, water accreting to graupel freezes, forming a layer
qHail falls but is eventually carried aloft again by an updraft where the process
repeats
qThe ultimate size of the hailstone is determined by the intensity of the updraft.
qGreat Plains = highest frequency of hail events
