CLEVELAND — How does hail form? Where does hail come from? Power of 5 Weather meteorologist Trent Magill explains...

Any thunderstorm can cause hail, if it has a strong enough updraft, and the updraft pushes raindrops high enough into the cloud where it's below freezing.

Those raindrops freeze. They grow heavier. They start to fall. An updraft pushes them back up as they melt and freeze repeatedly, growing larger and colliding.

The stronger the updraft, the larger the hail stones.

At a certain point, gravity kicks in, and those hail stones begin to fall at about 100 miles per hour.
