The chance of severe weather over the next few days brought storm chasers to Omaha on Saturday, including Steve Green, who prefers to be called a “tornado hunter.”

He created a Tornado Attack vehicle, a hybrid between a truck and a race car, to withstand being in the vortex of a tornado. It has military-grade windows, 90-some dashboard gadgets and weather reading equipment.

"The TA1’s designed to park in front of the path of the tornado and suck to the ground and stay there and allow the tornado to pass," said Green. "Air can't get under me. If the air can't get under me it can't lift me, therefore it gives me a security."

In the vehicle design you can see traces of his previous profession as a NASCAR driver. “Mother Nature's the most powerful force on earth and kills more people than racing ever will."

That realization set him on the ride of his life seven years ago when he created this machine, now worth a half-million dollars. "Somewhere over the rainbow in the Wizard of Oz, if you're on the right side of the tornado and you're in proper position, there's always a rainbow."

The car was put to the test during a twister five years ago in Mulvane, Kansas and it succeeded.

“I'll never forget what I thought was a giant piece of broccoli coming at me and when it got close, I realized it was a tree and I thought if that hits me it's gonna leave a mark."

While he’s had some close calls, Green is still trying to place his crew in another tornado. He says his goal is to collect lifesaving data and help scientists and forecasters.

Green hopes to get that opportunity early Sunday near Sioux Falls, South Dakota and southwestern Minnesota. That day, he'll likely head to Omaha for the chance of severe weather around the area Sunday night and Monday. Later Monday, Green plans to position himself and his crew somewhere between the Kansas-Nebraska border and North Platte.

"As strange as this sounds I hope we don't see anything because people get hurt and that's why we're trying to stop this."

The former racer and professional golfer has been largely self-funded until recently. Sponsorships from Flowmaster, WileyX, Traxxas and Ground Control have helped him continue his mission.
