Hailstorms can occur during the spring, summer or fall months. The majority of these storms appear between May and September.

What causes a hailstorm to occur?

Hailstones are formed when raindrops are carried upward by thunderstorm updrafts into extremely cold areas of the atmosphere and freeze. ... The hail falls when the thunderstorm's updraft can no longer support the weight of the hailstone, which can occur if the stone becomes large enough or the updraft weakens.

When and where does hail occur?

Where Does Hail Occur? Hailstorms are most frequent in the southern and central plains states, where warm moist air off of the Gulf of Mexico and cold dry air from Canada collide, thereby spawning violent thunderstorms.
