How does hail form?

KHOU Chief Meteorologist David Paul wants to keep you 'weather smart'

HOUSTON — Have you wondered how hail forms, even in the summertime heat of Houston?  Here’s how it happens.

Updrafts it he developing storms bring rain up high enough above the freezing level to form hail stones.  Sometimes these hail stones make several trips up and down through the storms, getting bigger with each round trip. 

On rare occasions, updrafts of more than 150 miles per hour can produce hail stones that can grow to become the size of grapefruits.

KHOU Chief Meteorologist David Paul wants to keep you 'weather smart.'  See some of the other videos he's produced in the playlist below.
