Hail is a form of solid precipitation. It is distinct from sleet, though the two are often confused for one another. It consists of balls or irregular lumps of ice, each of which is called a hailstone. Sleet falls generally in cold weather while hail growth is greatly inhibited during cold surface temperatures.

Hail! is a heavy metal supergroup / tribute band, formed in 2009. The band originally included Slipknot bassist Paul Gray until his sudden death in 2010.
