Fascinating session examining preliminary findings from @nsficechip.bsky.social with observations of an updraft of 150+ mph (5/25/25), addition of LDR to the dual-pol suite, and a lot of heterogeneity in hail swaths, particularly for high precipitation supercells

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

Fire ants 🐜, goat weed 🐐, and multi-frequency observations 📡📡🧊 of hailstorms 👍 @nsficechip.bsky.social

Walmarting. Living our BEST life in search of hail today. #DOWLife @nsficechip.bsky.social

Don’t have a mobile radar? What about a ruler 😁? (It’s that rectangular thing…usually about 12 inches long 😁)

Surveilling. Keeping it lean for this @nsficechip.bsky.social shake-out mission.

Sabrina Servey with the CMU team shares some initial hail swath distributions from three ICECHIP IOPs. #AMS2026

The CU Boulder UAS team highlighted RAAVEN imagery from two operational days, with the most impressive hail swath occurring near Winnett, Montana on June 15, 2025. #AMS2026

One of the most cherished parts of #ICECHIP was the large student involvement, with more than 70 students from over 13 universities contributing to the data collection. We thank them for their hard work and what a fantastic experience early in their careers!

I rode along with the meteorologists chasing the world's most extreme hail storms across the Great Plains in a massive effort improve our forecasts of these damaging events. Thanks to all involved in @nsficechip.bsky.social for having us. Had a hail of a good time. 🧪🌩️🌪️

Hail yeah! The ICECHIP field campaign (@nsficechip.bsky.social‬) has wrapped up, and the collected hailstones are being housed in the NSF NCAR Cold Lab for further study! 🌨️🔬 The project involved chasing storms from Montana to Texas to better understand the conditions that produce hail/hailstorms.

After 42 days and 15,000 + miles driven, #ICECHIP completed 24 IOPs across 11 states, including within 75 miles from both the Mexico and Canada borders. This totaled more than 10,000 hailstones collected by our teams while data was gathered on different types of hailstorms!

End of Season, ND Radars, Mesonets, Pods out 🎩 So happy to have been part of the @nsficechip.bsky.social field phase! After 24 IOPs…now the work begins 😁

Why not one for the road? We are stopping on the South Dakota/Minnesota border this afternoon with radars and our remaining ground assets to gather additional data on anticipated severe hailstorms!

Scanning hail-producing storms in North Dakota for @nsficechip.bsky.social…some dows get hail (and a rainbow!) and some dows get structure at their location

Today will be our “last dance” (officially) with severe hailstorms in North Dakota for the #ICECHIP effort. History was made as we collected, measured, and crushed over 10,000 hailstones across ~20 days. We are excited for the dataset that will be analyzed for many years to come!

During the 8-week @nsficechip.bsky.social project, #researchers used the latest technology to collect important #hail data. Hear from lead PI Rebecca Adams-Selin from Atmospheric and Environmental Research as she describes one of the more all-encompassing instruments – the SUMO.

While some teams have left to their respective homes, universities, or organizations, some remain out for the final day of official operations, which will occur tomorrow in North Dakota!

They are indeed crushing it! @nsficechip.bsky.social

Crushing it. What do you do with 4,000 hailstones that you collect while chasing storms

Dozens of researchers are chasing, driving and running into storms to collect fresh hail, getting their car bodies and their own bodies dented in the name of science.

As we head into our final days out in the Plains with #ICECHIP, we would like to give a huge thank you to our COW operators (PSU) and COW support (CU Boulder) for the long and hard hours they put in to making sure this C-band radar gathers the best data possible!

#ICECHIP makes its final return to eastern Wyoming today in search of large hail that may occur with any given thunderstorm this afternoon. Please tag us with interesting and large hail in this area!

Scan. Scan. Scan. Scan. Sample. Sample. Sample. IOP21 of @nsficechip.bsky.social underway in northern Nebraska. Mini COW (COW2) data at: svr.guru/data.php?id=...

Today, we anticipate a good case of hail along a cold front in northern Nebraska into southern South Dakota as we move into our 21st day of operations. Please let us know if you find any interesting hail in this area! Analysis by David Imy (SPC - retired)

The CU Boulder team flies an unmanned aircraft, called RAAVEN, behind hailstorms to sample the hail swath with a bird’s eye view. Flying perpendicular to storm motion gives an idea of swath extent while flying parallel gives an idea of hail evolution over time.
