How does hail,sleet and snow form?
Question Date: 2007-03-26
Answer 1:

Water vapor condenses into ice crystals at highaltitude where it is cold, and when the crystalsbecome large enough, the wind can no longer keep themaloft and they fall. Hail consists of droplets ofliquid water forming at low altitude and then beingbrought to high altitude and freezing by thunderstormupdrafts. They then fall, only to be caught in anotherupdraft, and repeating this process they add layerupon layer of ice until they finally fall to theground.
