Sean Waugh holds a laptop with green, red and yellow weather radar looping as his driver rumbles down an Oklahoma highway in their government-issued truck. The vehicle holds 50 gallons of fuel, so they can chase storms all day. A rectangular cage with metal mesh covers the truck in an attempt to protect the team from hail. Hanging off the front of the hail cage are weather instruments that look like the horn of a rhinoceros charging into a storm.

The truck, called Probe One, points in one direction, and a companion, Probe Two, points in another. Tall grass flows like ocean waves, and the stop sign at a crossroads wobbles. The sky is dark gray with a hint of green. Lightning flashes on all sides.

The radio cracks. “Probe One, you want us to go?”

“Yes, go now,” says Dr. Waugh, a researcher with the National Severe Storms Laboratory.

As they disappear into the mist, another storm chaser emerges: Reed Timmer, who has a large social media following, pulls in front in one of his tank-like trucks, called the Dominator.

It’s just the scientist, the YouTube star and a lonely farmhouse.

Sean Waugh’s job is to get close to storms. He’s lately become a Hollywood movie consultant in his spare time.Reto Sterchi for The New York Times
