Meteomatics and NOAA flew weather drones over Purcell, Oklahoma on July 30, demonstrating hexacopters that profile the lowest layers of the atmosphere on demand, exactly where tornadoes are born and where weather balloons and satellites leave forecasters half blind. I have covered drones flying into storms since the OPUS tornado intercepts in March, and this demo moves that story from stunt science to daily forecasting infrastructure.
Meteodrones Profile the Atmosphere Straight Up and Straight Down
The demonstration at the Kessler Atmospheric and Ecological Field Station put Meteomatics’ proprietary Meteodrones through their working routine: climb vertically, sample the air, and come home. Each hexacopter measures about 2.5 feet (76 cm) across, handles winds up to 50 knots (58 mph), flies in precipitation, and carries a de-icing system for freezing layers.
“It’s just like a weather balloon. It’s measuring temperature, humidity, wind, and pressure just straight up and straight down,” said Brad Guay, who leads government solutions at Meteomatics. The difference is control. The National Weather Service launches its balloons on a fixed schedule, twice a day, and each one drifts wherever the wind carries it before the instrument package falls back to Earth. A Meteodrone lands within a couple of feet of where it took off, gets reused, and flies whenever the forecast situation demands it, which is exactly when the atmosphere starts misbehaving between those two daily launches.
The aircraft are rated to 20,000 feet (6,096 m), and Meteomatics currently holds an FAA waiver to 10,000 feet (3,048 m) while it works on approval for higher flights. One researcher at the demo described the new data to KOCO as something like putting on glasses for the first time: a level of detail no satellite view from space delivers in the lowest atmosphere.
Oklahoma Became the Testbed Because Tornadoes Live in the Weather Kitchen
Oklahoma’s Mesonet weather stations are among the best surface networks in the country, and they stop measuring at 33 feet (10 m) above the ground. The drones extend that column beyond 3,280 feet (1 km), sampling the layer Guay calls the weather kitchen. “When tornadoes form, that happens in the lowest few thousand feet of the atmosphere,” he said.
The flights are not new theory. Scientists from the Oklahoma Mesonet, CIWRO, and the University of Oklahoma School of Meteorology have flown quasi-operational missions at the Washington, Oklahoma Mesonet station since December 2025. OU also brings its own aircraft to the effort: researcher Tyler Bell’s CopterSonde, built for everything from freezing air to Category 1 hurricane-force wind.
The early results already earn their fuel. “What we’ve already seen is that’s able to improve the lead time on thunderstorm development forecasts as well as predicting some more mundane things like when the fog will lift,” Guay said. Fog timing sounds boring until you run an airport or a solar farm. A planned expansion adds the Bixby Mesonet site in partnership with Oklahoma State University.
Europe Built the Networks While America Ran Pilots
Here is the part of this story that stings a little. Meteomatics, a Swiss company, already operates 10 Meteodrone sites in Switzerland and is building a 30-site network in Norway. The United States, home of Tornado Alley and the most violent low-level weather on the planet, is at the pilot-project stage with a single test site near Norman and one expansion planned.
The business model explains how it scales. NOAA already purchases observational data from roughly 70 partners under contract, according to Curtis Marshall, who directs the National Weather Service’s National Mesonet Program. Meteomatics slots into that same pipe: the agency buys the drone data, not the drones. No fleet to maintain, no pilots to train, just vertical profiles flowing into the forecast models.
Weather sensing keeps proving to be one of the quiet growth lanes for uncrewed systems. OPUS project drones flew into tornadoes for science in March, and Saildrone’s autonomous vessels patrol the Great Lakes on missions that run for months without refueling. The Meteodrone program brings that same logic to the vertical column above our heads.
DroneXL’s Take
The country with the worst tornadoes on Earth is buying its low-atmosphere eyesight from a Swiss company, and Europe got there first. Switzerland has 10 operational sites. Norway is building 30. Oklahoma, where the sky tries to kill people every spring, has one test station and a plan. That gap should embarrass somebody in Washington.
Still, I want to be clear about what impresses me here. This is the same versatility story I have reported all year from different angles: drones delivering burgers, flying whole blood between hospitals, dropping defibrillators ahead of ambulances. Now they are filling in the blind layer between the weather station and the satellite, the exact altitude band where a supercell decides whether to spin.
The forecast math is simple and brutal. Better data in the weather kitchen means earlier tornado warnings, and lead time is measured in lives. If a $100,000 drone network shaves even five minutes off a warning for one Oklahoma town, the program pays for itself in a single storm season.
I grew up reading Jules Verne, and I think about him more and more in this job. Machines that climb into the storm on schedule, sample the air, and land on the same square of grass sounded like his fiction not long ago. Now it is a Tuesday demo in Purcell. We are living the future he wrote, and I get to report it to you every day.
