  1. Hail By : Alyson and Kelly

  2. What is Hail and How its Made • Hail is a frozen rain drop, it is round and clear like an ice cube. • Hail is made in cumulonimbus clouds. Its made by raindrops moving up and down by wind blowing them.

  3. When Hail Occurs • Most of our Hail occurs in monsoon season between the dates July 7 and September 13. • But sometimes Hail can occur during a winter rainfall.

  4. Where Hail occurs • Hail can occur in the Great Plain States especially North Eastern Colorado and South Eastern Wyoming Receive more Hail yearly then any other part of the U.S. • Hail in this area of the country will fall late in the afternoon during the months of May and June is most likely.

  5. Conditions That Create This Weather • Hail begins as tiny ice pellets that collide with water droplets. The optimum freezing level for the formation of hail is from 8,000 to 10,000 feet. • The water droplets attach themselves to the ice pellets and begin to freeze as strong updraft winds toss the pellets and droplets back up into the colder regions of the upper levels of the cloud. As the attached droplets freeze, the pellets become larger. • Both gravity and downdraft thunderstorm winds pull the pellets back down, where they encounter more droplets that attach and freeze as the pellets are thrown, once again, back up through the cloud.

  6. KA-BAM • The damage that Hail makes can be very threatening . Hail can be as small as a pea, golf ball sized or as big as a baseball. When Hail hits the cars they can make a window shatter or get damaged really badly. Hail Damage
