Hailstorms in the U.S.

Hailstorms in the U.S.   This feature layer, utilizing data from the National Oceanic and Atmospheric Administration (NOAA), displays hailstorms in the United States between 1955 and 2025. Per NOAA, “Hail is a form of precipitation consisting of solid ice that forms inside thunderstorm updrafts. Hail can damage aircraft, homes and cars, and can be deadly to livestock and people. Hailstones are formed when raindrops are carried upward by thunderstorm updrafts into extremely cold areas of the atmosphere and freeze. Hailstones then grow by colliding with liquid water drops that freeze onto the hailstone’s surface. Hail falls when it becomes heavy enough to overcome the strength of the thunderstorm updraft and is pulled toward the earth by gravity.”
