Hail is generally associated with spring thunderstorms but may occur at any time of year. Hail is formed in huge thunderhead (cumulonimbus) clouds (Munez, 2000). During days when the soil is heated by the sun, the air near the ground also is heated.
Hail might seem like a minor concern, but it can shatter windows, leave pockmarks in siding and destroy or damage roof coverings. In an average year, hail causes more than $1.6 billion worth of damage to residential roofs in the United States, making it year in and year out, one of the most costly natural disasters.
