I’ve been hooked on tornadoes since I was a kid. I used to dream I was lying in my backyard as a black funnel cloud passed silently—and safely—over me. A shrink later told me the dream represented “safe danger,” but I never understood half of what he said, including that. As I grew older, I became a climate dilettante. I read about global warming and the coming ice age, wondered why barometric pressure affected dogs, and drew cloud charts in my daily planner. I saw Twister,of course. And I kept having that dream.

I wanted to see a real stormfor myself, but there was the business of finishing grad school and raising kids. So I back-burnered tornadoesfor decades and nearly forgot about them. Then,last winter, I saw a blurb in a travel magazine about stormchasing tours. I thought only Hollywood actors or meteorology nerds were allowed to chase tornadoes. But for $2,300 a week, I could, too. I justified it to mynow adult children, saying that if I died, at least it would be while doing something incredibly cool.

And I did. Not die—do something cool.

I decided to book theMayhem 1 tour with , one of some 20 stormchasing outfits in the country, whichpromises a 90 percent chance of seeing a tornado over the course of six days. Not onlywas the company vetted by the review site, it had fewer people per vanand was relatively affordable compared withothers (many run$2,500 and up). Alltrips are based out of Tulsa, Oklahoma, the epicenter of Tornado Alley, a swath of land that runs from central Texas to South Dakota andspawns many of the approximately 1,200 events each year.

While I knew Oklahoma and the southern plains were likely to produce tornadoes in May and early June, a periodwhen cold fronts from the Arctic that haven’t been weakenedon their way southmeet the warm air from the Gulf of Mexico, I still had to manage my expectations—there are never guarantees when it comes to weather. But after arriving at my motel in Tulsa last summer and turningon the Weather Channel,it reported a tornado near the town of, a little over three hours west, around 6:30 P.M. I was optimistic.

The next morning, I metowner and operator Lanny Dean: think Michael Moore with the baseball cap turned backwards. A tuft of hair sprouted through what my daughters call the “ponytail hole.” He’s a big, affable man in his mid-fortiesand was wearing a T-shirt with“Outlaw Chasers”printed on the front. (The back read“Show Me or Blow Me.”) With him was a guy namedMike, a forty-something out of San Antonio and my fellow chaser. Mike had already been on tenchasing tours, many of them with Dean. There was supposed to be another couple with us, but they bailed at the last minute.

Dean was seven years old and sitting in the back seat of the family car when he firstsawa twisting, funnel-shaped black cloud skitter across the Texas landscape, plucking boards off the side of a barn. “Shit, yes, it terrified me,” he said. “It was the most scary, awe-inspiring thing I’ve ever seen. It’s what hooked me.”

The fear turned into fascination.At Missouri State, he did some undergraduate work in atmospheric science (“akick-ass field,” he said) and ended up with a Bachelor of Sciencein electronic engineering telecommunication. He later became a severe-weather reporter and photographer and starred in TruTV’sTornado Hunters. Since launching his guiding company in 1999, he’s seen 581tornadoes and13 major hurricanes up closeand has held hail the size of a softball in his hand. He’sa frequent video contributor to Good MorningAmerica.His 2008 Dodge Grand Caravan has some 300,000 miles on it. The van’s been battered and busted, it’s sloshed through the kind of deepmud puddles you only see in car commercials, and has a shattered side mirror. But it’s clean,well-maintained, and Dean only smokes at gas stops. Between thisvan and his previous chase vehicle, he figures he’s driven 700,000 miles since he started as a guide. He’d been thinking of springing for a new rig.

Mike rode shotgun. A Lenovo computer was mounted to the passenger-side dashboard anda monitor to the back of its seat, so I could see what they were looking at. After Mike pulled up RadarScope, a weather app used by everyone from meteorologists to emergency responders,he and Dean started chatting aboutbase reflectivity, super-res velocity, something called CAPE, and rear-flank downdraft. Dean eyed me in the rearview mirror, saying, “You’re gonna hear a lot of verbiage. You’re not gonna understand it, but I’ll keep yakking until you do.”

“It’s a good chase day,” hetold us. “There’s a mess of convection near Gotebo, so we’re busting south.”We hauled out of Tulsa and soon passed Oklahoma City. “We’re going to play the dry line”—a separation between the warm,humid air from the Gulf andthe hot, dry air from the desert Southwest—“and go for broke.” In other words, a flurry of movement driven by a rising air mass was a promising enough indicator for a superstorm that Dean felt the three-hour drive to Gotebo was worth it.

A few hours later, a mass of red dots appeared on the monitor. “Those are other chasers,” Mike explained.

“And those are just the guys with their beacons on,” Dean added. “For every dot you see, there are probably five to tenother guys like me who’ve turned their icons off.” If you click on a dot, the chaser’s name and phone number pops up. Since Dean’s a professional stormchaser, if his icon is on, chasers will start chasing him, like bikers drafting off the lead cyclist duringthe Tour de France.

Anyone can call themselves a chaser. There’s no licensing or certification required, just enough gall to get close to a storm and enough brainsto know when to retreat. Equipment helps, but having a cell phone with a couple of appslike and RadarScopeand tuning into the station will do. Stormchasing started catching on after the movieTwistercame outin 1996. (Dean hated it. “Nobody—nobody—drives through a cornfield,” he said. “They just don’t.”) Spurred byits success, a handful of stormchaser shows further helped capture people’s imaginations,whilethe development of new technology,such asGPS units made for civilian use,made it possible for others to do it themselves. Since thenit’s not only become a popular pastime amongmeteorologists, researchers, and photographersbut adrenaline junkies who treat it as an obsessive quest, on a par with eclipse chasers and high pointers. According to Dean, the addiction is very real—77 percent of his guests are repeat customers.

Dean’s safety and expertise are among the reasons many chasers return to chase with him rather than attempt to head outon their own. And those are good reasons when it comes to this activity—according to the,tornadoes are one of the maincauses of property destruction in the U.S., second only tohurricanes, which also wreaksignificant havoc, as we recently witnessed whenmade landfall.Despite this, records of stormchasing incidentsshowthat weather-related fatalities arelow compared to the risk posed by other chasers. In 2019,the community websitereported that12 of the 15known stormchasing-related deaths were the

We pulled off at a Kum and Go gas station to fill up the tank. Road rule: pee at every stop. Mike recalled how his best tornado video was ruined by someone chanting, “I’ve gotta pee,” like a mantra. Fortunately, I have a capacious bladder, but Dean keeps a roll of toilet paper in his glove box, just in case.

Back in the car, Dean was refining our target area near Gotebo, checking RadarScopeand the real-time Doppler radar, which tracks the location and velocity of storms,and referring toGRLevelX, adata-processing and display program. His cell phone pinged with text messages from chaser friends in the area. By midafternoon, the National Weather Service had issued a severe weather warning on NOAAWeather Radio, andour area on the RadarScope screen was then boxed in yellow, indicating heightened weather activity.

The sky was dark and getting darker.

“We’re in a multicellular complex,” Dean said.“We’re banking on finding an isolated cell. A tail-end Charlie. You see where I’m going with this?” I got the cell part—the event contained manyair masses that were drafting up and down in convective loops, producing forceand fighting for dominance, and we needed to find an isolated cell, which has a higher chance of producing tornados because it’s less likely to be tempered by the force of others—but I wasn’t so sure about Charlie.Dean explained that this isslang for the southernmost part of a squall line that can produce the highest severe weather because it will usually deviate from the main cell cluster.

At5:25 P.M., the county sent out a “tornado warned” signal. A red line supplanted the yellow one on the RadarScope screen.

We passed througha residential neighborhoodin Carnegie, a rural town near the southwest corner of the state. Despite the tornado warning, people were gathered under porch awnings, and couples stood under umbrellas holding hands as if watching a sunset. There were guys—meteorologists, reporters—broadcasting in the rain, hoods flapping around their heads like sails, cameramen inches from their faces. We soon passed a dual-pole Doppler radar truck, which sends both horizontal and vertical electromagnetic waves that help determine if a tornado is on the ground (among other things),and anambulance with the Red Cross symbol on it. Everyone was shooting video. Everyone was staring at the sky. The air was heavy with expectation.

When we reached Mountain View, Oklahoma, the road was clogged with chasers in their pickups. “It’s a chaser convergence,” said Dean. “The last place you want to be when you’re around a tornado is in a .”

“Why isn’t everybody inside?” I asked.

“It’s Tornado Alley,” Dean said. “It is what it is.”

Mike added, “We’re out here, aren’t we.”

Ten minutes later, we pulled onto a dirt roadand watched as a black wall of clouds descended over a field, about an eighth of a mileaway. Half the sky was day bright; the other half, night. Dean pointed out a small, midlevel funnel and some rapid rotation at itscloud base. Reddish-brown dirt was whirling in the distance.

“That’s an EF-1,” Dean guessed. EF refers to the Enhanced Fujita scale, which doesn’t rate a tornado by wind speedbut by the extent of damage it produces. Forget Hollywood:most tornadoes—over 77 percent of them—are EF-1 or lower, movingat 86 to 110 miles per hour and strong enough to tear the shingles off a roofbut not shear a house off its foundation.

I was soon standing in a field, camera in hand, looking for a funnel—that entrail from hell that sucks up tractortrailers and Helen Hunt’s father. “It’s a rain-wrapped tornado,” Dean said. “The funnel’s behind the curtain of rain. You don’t want to be driving into one of these thinking you’re just going through a storm.”

I’m thrown off by this rain-wrapped thing. It looked like a typical storm, but I could sense an unusual power behind it. And not seeing thefunnel made it easier to stand there than if there werea torquing tube coming right for me. Not that that’s going to happen—because Dean’s no hotdogger. He’ll get you close to a tornado, but he won’t kill you.

Funnel or no funnel, it was a behemoth.

We watched as the black rainstorm dissipated, revealing the object of our search behind it.“There’s our tornado,” Dean said, referring to the fact that a tornado is only a tornado once it hits the ground. The whole timeMike and I stood there taking pictures, Dean was watchingthe RadarScope app on his cell phone. The tornado was moving closer.“Gotta go,” he said.“Now.” We piled into the van and hightailed it out of there,Dean keepingone eye on the app and the other on his rearview mirror as he removed us from itsrange.

By the time we’dhad dinner and set out to find a place to spend the night, the motels around El Reno, northeast of where we’d spotted the tornado,were full, thanks to the chaser convergence.During peak season in Oklahoma, storms can attract a couple thousand chasers. We finally found lodgingoutside Oklahoma City. “Just so you know,” Dean remarkedas we weresaying goodnight, “seeing a tornado on your first chase day just doesn’t happen.”

He’s right. The odds of seeing a tornado—on any day of a tour—are slim. Stormchasing companies all post the same disclaimer: severe weather not guaranteed. One chaser drove up and down the Great Plains for four years before spottinghis first. On the other hand, one of Dean’s tours came acrossfive tornadoes in one dayas the groupcrisscrossed the Four Corners states.

The next morning, I ate my cereal staring at the back of a WeatherNation TV stormchaser pickup in the parking lot. Four cups of coffee later, Mike and Dean came down,and we got to planning. Mike was paying by the dayso he could opt out if there was no weather. Which is what he decided to doafter he and Dean poredover the forecasts. It was a “blue-sky bust,” said Dean—no chaseable weather in the plains. Mike scrambled to hopthe first flightback to San Antonio.

The tour was suddenly just Deanand me. I got to sit up front. I only hoped hewasn’t going to ask me to interpret radar images or find escape routes on Google maps. He soon decided that we should leave Oklahoma City for Springfield, Missouri, to get in a position for possible weather in the next day or two.On the 200-plus-mile drive, Dean talked about the time he drove a chase group 600 miles from Denver to Hobbs, New Mexico. Shots were poured each time they saw a tornado. Better yet, tattoos were inked. Dean rolled up the sleeve of his T-shirt and showed me adark blue twister on his biceps.

I noticed a couple of bright orange cones in the back of the car. “What are those weird things?” I asked. “They’re probes,” Deansaid. “I’m trying to determine the signature frequencies of the sound a tornado makes.” I told himI’d heardtornadoes sounded like a locomotive roaring towardyou.“Not those sounds,” Dean clarified, “infrasonic sounds, the sounds tornadoes make that the human ear can’t hear.”Turns out, beneath the camocap and “Show Me or Blow Me” T-shirt, Dean is a serious tornado researcher who’d founded his owntornado field-research company, , in 2007. The tours pay forresearch,which he publishes pro bono. Support from Microsoft doesn’t hurt, either.

The following day, we’reskunked by the weather again. “Mother Nature is a fickle bitch,” Dean said. “The cold front shut us down. We need to wait for the atmosphere to re-destabilize again—get some shear, get some lift, some stuff to create a supercell to kick out a couple of tornadic thunderstorms.”

What do chasers do when there’s no weather? Field-trip. We hit the road for historic Ozark City in southwestern Missouri, grabbinga bite to eat at some joint claiming to serve the world’s best grilled-cheese sandwich. (It wasn’t bad—they just threw in some avocado; the potato salad, however, was awesome.) Theday after, I yanked open the motel shades to beautiful blue skies. Dean was dejected. Time for another field trip. The choice was between the Ozark town of Branson, Missouri, home of the and the , or Springfield and the Bass Pro Shop’s . We chose penguins over Parton.When we stopped for gas at yet anothertruck stop, a few customers came over to gawk at Dean’s tricked-out van with its ham-radio antenna, roof-mounted weather vane, onboard computer, and Good MorningAmericaID dangling from the rearview mirror. “You a chaser?” a guy asked.

Dean gets this all the time. Like, all the time.

Most of the time he’s patient and polite, “Yes, sir. We’ve been out in the western part of the state chasing a supercell storm.” But on a bad day, when the questions keep coming (“What’s that thing on top of your car?”), he might say, “It’s a dickfer.”

“What’s a dickfer?”

Today is not a bad day. At least not that bad.

The next day, the sky isdark outside my window. At breakfastDean textsme a screenshot from the Storm Prediction Center showing a marginal risk for severe weather near Asbury, Missouri, 80 miles west of Springfield. Hetells me he was up until 2 A.M.running a forecastand passesme a hand-drawn diagram of our play for the day. It’sa swarm of blue and green markers, with curving isotherms and notations scribbled all over the page: CT=74°,LCL 1,500 m,LCF,CAPE 500-600 J/kg. He then startstalking about LEWP, ASO, CAMS, and HRRR,acronyms that sounded as if somebody had kicked over a set of alphabet blocks. After making his own predictions, Dean checked in with the (part of the National Weather Center) in Norman, Oklahoma—the epicenter of severe-weather research—to see what the “the Ph.D.’s are saying.”

Despite the slight risk, Dean tellsme that the day’s readings havethe best potential for severe weather on the plains. “So we’re golden,” he said. Our target area was west of Springfield, past Joplin, the site of the that ripped through the city and killed 158 people in 2011. When we got there, Dean showed me the scorchedearth marks—places where the tornado yanked the soil out of the ground—and the debarked trees.

“Weather needs time to unfold. Things need to happen,” Dean said. “SixP.M. is the magic hour.” By the afternoon, the temperature had dropped from 84 to 59 degrees. We had moved to Pittsburg, Missouri, just northwest of Asbury. It started to rain hard. The closer we got to the supercell storm, the less Dean needed to look at radar and models. “We’re sight chasing,” he said—relying more on experience, observation, “and your gut.” Pretty soonwe lost cellular service. Dean’s text pings were silenced, the RadarScope imagefrozen. “Now,” he said, “we’re blind chasing.” After a minute, we hit the hail.

At6:45 P.M., the National Weather Service issued a severe thunderstorm warning on NOAA Weather Radio. “Hell, yeah,” said Dean, giving me a fist bump. “We went from a 2 percent chance of severe weather to quarter-size hail.” He jumped out of the car, shot some video, and uploaded it to the ABC server for Good MorningAmerica.For about an hour, we watched Mother Nature in her drama-queen mode—epic lightning, ear-splitting thunder, and pummeling hail. “Anytime weather becomes a nuisance,” he said, “it’s newsworthy.”

Then, suddenly, it gotquiet. The storm had collapsed, the weather morphed from monster to mouse. It left as fast as it came, leaving me wanting more but exhilarated that we’d caught one with a mere 2 percent chance.

On the last day of my trip, Dean picked me up and drove me from Springfield back to Tulsa so I could catch a flight home. The whole time he was gabbing about the weather prospects for his upcomingMayhem 2tour, I was wondering what the protocol was for saying goodbye to someone you just spent five days in a car withalone. The term“intimate stranger” came to mind, but I didn’t know if it was really apt or the name of some movie. When we arrived, I thanked Dean for the great experience and reached out to shake his hand. He grabbed it, yanked me toward him, and gave me a bear hug with a hearty back pat.

As I watched Tulsa become a patchwork of fields, something Dean said popped into my head: “Once you see your first tornado, it’s the best drug you’re ever gonna have. And that’s your fix. You’ll do anything to get it, and you’ll do it over and over.”

You see where I’m going with this?
