How do hailstones grow inside storm clouds?
WeatherPrecipitation
Quick Answer
Hailstones are built by repeated trips through strong updrafts in thunderstorm clouds, where layers of ice freeze around a small core. They can grow large enough to fall as damaging ice balls.
The Full Story
Hail forms in severe thunderstorms when strong updrafts carry ice embryos upward into very cold regions of the cloud. Supercooled water droplets freeze onto the stone, adding layers each time it is lifted and dropped. The size of hail depends on the strength of the updraft and the time the stone spends cycling through the cloud. Large hail can fall at dangerous speeds and is a major cause of crop and roof damage.
