Imagine the force of the wind it takes to blow a particle of ice the size of those monsters upward accumulating layer after layer of ice until they're too heavy to remain aloft. Then they come down with devastating results. *That* is some heavy weather.
I have family that until recently lived in Moore, Oklahoma, otherwise known as the center of the bullseye in Tornado Alley (it's just south of Oklahoma City). They've had tornadoes pass within half a mile (!!!) of their house; they've had hailstorms where I've seen pictures of holes in the yard that could hide a grapefruit. The weather was Just. Too. Much. so, now they're in Florida.
