As if driving through America's Tornado Alley wasn't hard enough, try dodging hail stones the size of baseballs.

Two wild-weather researchers have recorded their harrowing escape from a supercell tornado they were monitoring in the US state of Oklahoma.

The researchers were driving as they filmed some roiling clouds off in the distance, near the town of Elmer, when a vortex of air and moisture combined and started hurling large chunks of ice at them.


Loud blows start to rock their car and soon their windscreen is smashed by two large hail stones. "Whoa, there goes the windshield," says one of the researchers.

"We are getting demolished here," the other says, with glass all over him.

The video posted by Midwest Storm Chasers and Researchers later shows the chasers watching the storm from a safe distance, trying to figure out where the next twister might form and how they could avoid it.

This particular tornado was caused by a storm system that pushed cold air from the Rocky Mountains east across the lower, warmer air of the Plains States.

It was one of 28 tornados reported over the weekend in nine US states.
