Doppler on Wheels (DOW)
@dowfacility.bsky.social
I am an array of mobile/deployable weather radars (DOWs/COWs), weather stations, disdrometers, mesonets, & soundings. I look best in Carbone42.
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 💾👇
Josh Wurman showing off the latest and greatest DOWA 😁 to the @climasillinois.bsky.social students and @kakosiba.bsky.social showing tornado 🌪️ data from the 2026 season 🤩! As always, a great group of students…and always happy to talk all things DOW 😁!

Read all about it 📣📰! Latest updates on DOW tornado damage and evolution research. DOWs prepping to go out when atmosphere remembers that it is tornado season 🌪️
American Meteorological Society@ametsoc.org · 2mo agoThe storm-chasing @dowfacility.bsky.social research team got close observations of the devastating Greenfield, IA, tornado and powerful Duke, OK tornado in 2024. Those observations reveal new insights on how tornadoes evolve--and how they do damage. Read more: https://bit.ly/4uF6GG6
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
DOW A’s view of the tornado near Saint Libory, NE at 2 different times Image 1: 2211 UTC with eye Image 2: 2213 UTC with debris ball
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
Scanning a circulation just east of Goodland at 2338 UTC.
Fire ants 🐜, goat weed 🐐, and multi-frequency observations 📡📡🧊 of hailstorms 👍 @nsficechip.bsky.social
Watching the Early Rod Run…from the sidelines ☹️
Walmarting. Living our BEST life in search of hail today. #DOWLife @nsficechip.bsky.social
Analyzing large debris with LDR for 1st time ever in a tornado (!) & learning how vortex mergers affect tornado intensity from data I collected during the active 2024 tornado season then going out again for more 2026 tornado & hail data!
American Meteorological Society@ametsoc.org · 3mo agoAs severe weather season kicks off, the Doppler On Wheels team @dowfacility.bsky.social and Girls Who Chase @girlswhochase.com are getting up close with the most intense tornadoes & hailstorms they can find. Their goal? To help uncover why and how some storms become monsters. https://bit.ly/4dd7xGq
The pressure 😁 is on…sparks are flying to get new hydraulics before next 🌪️🧊mission!
Don’t have a mobile radar? What about a ruler 😁? (It’s that rectangular thing…usually about 12 inches long 😁)
ICECHIP@nsficechip.bsky.social · 3mo ago🚨CALLING ALL CHASERS🚨 If you’re out chasing, you’re in a unique position to capture some of the most valuable hail observations available. We invite you to contribute your hail reports to the ICECHIP database and help improve our understanding of severe hail events. icechip.niu.edu/submit_repor...
MiniCOW moovie (with swarmsondes!) of almost/maybe tornadoes near Mill Creek, OK on 4/25/2026. #okwx
MiniCOW packs MegaPOWER! Observes birth and ingestion of satellite tornado and Fujiwara effect deflecting tornado. Tornado transitions 2x between clear eye and debris ball. Prelim data from most powerful mobile radar, 1 MegaWatt C-band storm-penetrating miniCOW in Braman, OK 🌪️
DOW (🐮📡) observations of the tornado 🌪️ near Braman, OK on 4/23/2026
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
3rd Annual FARM Radar institute DEADLINE EXTENDED until Monday, 27 April at 1159PM MDT! (Turns out my people are slackers…and didn’t answer questions very timely 🙄)

Doppler on Wheels (DOW)@dowfacility.bsky.social · 4mo agoIt’s baaaack 😁! The 3rd FARM Facility Radar Institute runs from 25 June - 1 July 2026 in Boulder, CO. If you have completed at least 2 years of college in a math/science/engineering/tech major…Apply to spend a week with me 😃!
Mini 🐮📡 sending up *some* real-time data from our deployment near Delaware, IA. (I just take the data…the humans plot it…and then put labels over the interesting parts 🙄). Link to real-time data website in comments 👇
Surveilling. Keeping it lean for this @nsficechip.bsky.social shake-out mission.
Don’t be a Daria…

Time to clear out the mice 🐭…headed east and then ???
Once tornadoes form how do they keep going? How do they get stronger or weaker? With help from data from yours truly 📡 we are learning more about how tornadoes evolve 🌪️🌪️. Link 👇 headlines.ametsoc.org/2025/12/30/d...
