17 years ago today! As part of VORTEX2, we parked in front of an incipient tornado and collected coordinated data (also I still thought radomes were cool 😎). Lots of papers were written about the Goshen tornado using DOW data! Learn more by going to our retro cool website 💾👇

Swirls, whirls, and windshield cracking hail 😬. All in a days work near Seibert, CO on 5/21/2026! Some of those swirls and whirls crossed our delta-V = 40m/s, “it’s a tornado”, threshold 🌪️ @nsficechip.bsky.social

Under the mini COW 🐮 and Dow radar umbrellas 📡☂️, the heavy lifting was being done by the Pod People 👾! Pods were deployed near Coby, KS collecting the all-important thermodynamic and surface wind data in these hail storms 🧊! @nsficechip.bsky.social

DOW obs of Lena, IL tornado on 4/17/26. *Very* prelim: Lots of change min to min. 🌪️Max Winds ~120 -130 mph (EF2) on east side. Obs 1300 ft above radar so might be stronger lower. Clearly lofting debris before & in town 🌪️At times large ~ 3000 ft in diameter #ilwx

A powerful tornado swept over Greenfield Iowa in 2024, causing widespread damage, killing several people. DOWs captured 300 mph winds! House-by-house comparisons of DOW winds vs damage & videos of turbine collapse allow better understanding of tornado winds vs damage. Link 👇
