Every storm is composed of the same fundamental DNA — in this case, moisture, unstable air and something to ignite the two skyward, often heat. When the earth warms in the spring and summer months, hot wet air rushes upward in columns, where it collides with cool dry air, forming volatile cumulus clouds that can begin to swell against the top of the troposphere, at times carrying as much as a million tons of water. If one of these budding cells manages to punch through the tropopause, as the boundary between the troposphere and stratosphere is called, the storm mushrooms, feeding on the energy-rich air of the upper atmosphere. As it continues to grow, inhaling up more moisture and breathing it back down as rain and hail, this vast vertical lung can sprout into a self-sustaining system that takes on many different forms. Predicting exactly what form this DNA will arrange itself into, however, turns out to be a puzzle on par with biological diversity. Composed of millions of micro air currents, electrical pulses and unfathomably complex networks of ice crystals, every storm is a singular creature, growing and behaving differently based on its geography and climate.

With so many variables at play, it became apparent to modern meteorologists that predicting storms required sampling as many as possible. The perfect repository, as it turned out, existed in the Great Plains, where many of the world’s most dangerous storms are born. Here, in the spring and summer months, moist air off the Gulf of Mexico pools with dry air from the Arctic and southwestern deserts, which is all then corralled by the Rocky Mountains, forming a massive eddy. For meteorologists, this sustained volatility has made the plains the de facto national laboratory, where about 30 National Weather Service offices, tens of thousands of private radars and weather stations and hundreds of airports are sampling the air conditions before, during and after storms. Each sample, whether taken by radar or wind gauge, is a snapshot of that particular storm’s behavior and composition — such as air density, pressure, temperature, humidity and wind velocity — providing meteorologists a profile to look for in the future.
