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

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

🚨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...

Photos and notes on storm context or damage Even reports of no hail observed are useful for validation and improving spatial accuracy. E.g., when you are measuring across a hail swath, feel free to submit a report to note that no more hail is observed.

Your contributions directly support research on hail size distributions, storm processes, and impacts...helping bridge the gap between field observations and forecasting.

We’re especially interested in accurate measurements, not estimates. When possible, please report: Maximum dimension (Z) — the largest distance across the hailstone X and Y dimensions — measured perpendicular to each other Weight (grams) — optional but extremely valuable.

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!

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!

Después de 42 días y más de 15,000 millas recorridas, #ICECHIP completó 24 POIs en 11 estados, incluyendo zonas a menos de 75 millas tanto de la frontera con México como de la frontera con Canadá...

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!

¿Por qué no una para el camino? ¡Esta tarde nos detendremos en la frontera entre Dakota del Sur y Minnesota con radares y nuestros recursos terrestres restantes para recopilar datos adicionales sobre las tormentas severas graniceras que se anticipan!

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!

Hoy será nuestro “último baile” (oficialmente) con tormentas serveras graniceras en Dakota del Norte para el proyecto #ICECHIP. Hicimos historia al recolectar, medir y aplastar más de 10,000 granizos en aproximadamente 20 días...

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!

Mientras algunos equipos se han ido a sus respectivos hogares, universidades u organizaciones, otros permanecen aún en la campaña para el último día de operaciones oficiales, ¡que tendrá lugar mañana en Dakota del Norte!

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!

A medida que nos acercamos a nuestros últimos días en las Planicies con #ICECHIP, ¡queremos agradecer enormemente a nuestros operadores de COW (PSU) y al equipo de apoyo de COW (CU Boulder)…

#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!

#ICECHIP hace su regreso final al este de Wyoming hoy en busca de granizo de gran tamaño que puede ocurrir con cualquier tormenta eléctrica esta tarde. Por favor, etiquétennos si encuentran granizo interesante o de gran tamaño en esta área.

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)

Hoy, anticipamos un buen caso de granizo a lo largo de un frente frío en el norte de Nebraska y el sur de Dakota del Sur, mientras avanzamos hacia nuestro día 21 de operaciones. Por favor, infórmenos si encuentran algún granizo interesante en esta área.

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.

El equipo de CU Boulder vuela una aeronave no tripulada, llamada RAAVEN, detrás de tormentas de granizo para muestrear el área de impacto del granizo desde una vista aérea...

…Volar perpendicular al movimiento de la tormenta da una idea de la extensión de esta área, mientras que volar en paralelo proporciona información sobre el desarrollo del granizo a lo largo del tiempo.

After more than 30 hours of driving from MT to the TX panhandle and back north over the last few days, #ICECHIP teams have returned to the 46th parallel, this time in ND! Ground team and radar deployments on severe storms will occur this afternoon as significant hail is possible.

Después de más de 30 horas conduciendo desde Montana hasta la región del Panhandle de Texas y de regreso hacia el norte en los últimos días, los equipos de #ICECHIP han regresado al paralelo 46, ¡esta vez en Dakota del Norte!…
