Hail begins as a drop of water falling toward earth. In conditions that produce hail, rain clouds and such, there are areas were the wind blows downwrd and also upward producing very turbulent conditions. There is very cold air in the upper atmosphere. As a drop o rain(mostiure) falls, it is caught by updrafts of air and pushed high up into the very cold air and the outside of the mosture crytalizes into ice. This may occur a few or many times and the number of times the drop returnsto the upper atmosphere determines the size of the hail, for each time the drop travels upward more ice forms and the drop increases in size, until finally there is so much ice attached until gravity takes over and pulls the drop, which is now what we know as hail, down and out of the effect of updrafts and it falls to earth. In every piece of hail there is the minute drop of water that developed into he ball of ice we know as hail.
Hail is most likely to occur during the spring and summer months when warm, moist air near the ground rises rapidly into colder regions of the atmosphere. This rapid upward movement of air creates strong updrafts that can cause water droplets to freeze and form hailstones.
Hail and tornadoes are most often associated with cold fronts, but can occur with dry lines or, lest often, warm fronts.
Cumulonimbus clouds are most likely to result in hail and lightning. These are large, towering clouds associated with thunderstorms. The strong updrafts and downdrafts within cumulonimbus clouds promote the formation of hail and the development of lightning.
A cold front is most likely to bring hail and tornadoes into an area. As the cold front advances, it forces warm, moist air to rise rapidly, creating instability that can lead to severe thunderstorms, hail, and tornado development.

hail
Hail is found anywhere thunderstorms occur, especially severe storms. This would be most places in the mid-latitudes, especially continental locations. The tropics have lots of thunderstorms but not as many generate hail. Some of the most frequent hail occurs in mountainous areas due to the orographic lift that allows updrafts to become stronger. It is very common and hail can be quite large in northern India and parts of China. Hailstorms can also occur frequently across much of Europe.
