Hailstorm is an extreme weather condition occurring during rain. Hail forms when rain- drops pass through very cold air in the atmosphere and get frozen into the balls of ice. These balls of ice fall on the ground as hail stones. When the falling of the hail is accompanied by thunderstorm, the resulting condition is known as a hailstorm. Hailstorm develops when the air mass in the atmosphere is unstable and the temperature fall is much greater than the normal.
