On May 30, 2012, at 3:00 P.M. MST, a series of thunderstorms formed over central and south central Kansas. They dropped golf ball-sized hail before lining up into a dark vanguard that barraged the countryside ahead with 70 mile per hour winds. News of the derecho—a long-lived line of fast moving thunderstorms with winds of more than 58 mph—led Brian Johnson to grab his camera and venture out to an open field where he had photographed lightning the previous night.
The amateur photographer chases big storms for a series of local radio stations. He fell in love with the behemoths at the age of seven, after witnessing the fury of a tornado up close. "My father still regrets saying the words 'Look at that,'" said Johnson. "Remember, if you take a frightened child out into a storm to show them how beautiful nature’s fury can be, they may turn out like me."
Johnson's photo was one of five winners selected for NASA's Global Precipitation Management Extreme Weather Photo Competition. The agency's Global Precipitation Management satellite captures data about rainfall and snowfall from space. Read on for the stories behind the space agency's favorite images, filed by people shooting in the storms' paths.

“As a large squall line moved through the area. The National Weather Service had warned about a large scale Derecho forming and moving through. This spawned a couple brief severe thunderstorms that dumped hail on rush hour traffic before the main line moved in. As the bigger storm moved into the Wichita area, reports were coming in of 70 mph winds and hail. There is an open farm field roughly two miles from my house that I shot lightning on the previous night. I sat there for about 20 minutes before this large squall line pushed through the clouds. I was hit with a pretty good gust front as it got closer, but as the winds increased, I decided to get to shelter. This photo was one of the last ones I took.

"Ormond Shelf," May 15, 2012; Ormon Beach, Florida Photo: Jason Weingart“I'm a photography student at the University of Central Florida. I began chasing storms a little over three years ago. This day started out like many other days. I was out on a storm west of the coast, photographing it even as the National Weather Service issued a severe warning. The NWS lifted the warning, but I decided to stick with it as it moved to the coast. Just as it started to move offshore to the east, it made a turn to the south.
I have shot many storms from the same spot this photo was taken, and I almost drove by to get a different vantage point, but something told me to just stop at my spot. I jumped out of my car and ran down to the beach. To my surprise, there were still several beach-goers taking in the sight of this massive shelf cloud, as well as a few surfers in the water, trying to catch one last wave. Of course, there was a Volusia County lifeguard standing there watching over everyone. I walked down to the water and took some shots, always keeping an eye on the lifeguard. As the shelf cloud approached, I swung back behind the guard tower, waited for him to climb up it and signal to the surfers to exit the water. I took several shots, then hopped back in my car and tried to stay south of the storm.
The storm actually pushed back on shore as it moved south, and then became strong enough for tornado warnings on three separate occasions. I saw a large wall cloud, another spectacular shelf cloud, and some very tight rotation in the couple hours I stuck with the storm after I left the beach in Ormond. Had I known what I already shot there, I probably wouldn't have even bothered. Definitely my signature shot of the year."
