Evidence / storm surfaces
How Gillette saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Jul 17, 2026 — this storm produced no NEXRAD point detections over Gillette, so there is one map to show, not two.
The storm in context
Where Jul 17, 2026 sits in Gillette's hail record.
This was Gillette's 11th recorded hail day, arriving 9 days after the Jul 8, 2026 storm. By severity it ranks 11th of the 13 storms we have logged here. Radar put the day's largest stone over Gillette at 0.75" — radar-estimated size aloft.
The Jul 17, 2026 convective day was bigger than Gillette: the same system put hail over 415 other tracked cities, 1 of them in Wyoming. Nearest: Moorcroft (61 miles northeast, up to 0.5"); Custer (80 miles east, up to 1"); New England (228 miles northeast, up to 0.5").

Ground reports
What people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.
No ground reports were filed with the National Weather Service for this storm over Gillette. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Near the severe threshold
What 0.75" hail means for Gillette roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.
