What causes hailstones rain?

What conditions are needed for hail to form?

Formation. Hail forms in strong thunderstorm clouds, particularly those with intense updrafts, high liquid water content, great vertical extent, large water droplets, and where a good portion of the cloud layer is below freezing 0 °C (32 °F).

Where does hail storm come from?

Weather Wisdom: Hail

Hail is generated in a thunderstorm, and is really just frozen raindrops. A thunderstorm contains winds that blow rapidly downwards (a downdraft) and rapidly upwards (an updraft). Raindrops inside a developing thunderstorm are carried aloft by updrafts.

How do raindrops become hailstones?

Hail is a large frozen raindrop produced by intense thunderstorms, where snow and rain can coexist in the central updraft. As the snowflakes fall, liquid water freezes onto them forming ice pellets that will continue to grow as more and more droplets are accumulated.

Where was the worst hail storm?

The costliest hailstorm in US history struck the I-70 corridor of eastern Kansas, across Missouri, into southwestern Illinois producing many baseball-sized hail reports.
