Independent storm reports filed with the NWS.
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.
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 Jun 17, 2026 — this storm produced no NEXRAD point detections over Auburn, so there is one map to show, not two.
This was Auburn's 5th recorded hail day, arriving 6 days after the Jun 11, 2026 storm. By severity it ranks 2nd of the 5 storms we have logged here. Radar put the day's largest stone over Auburn at 0.75" — radar-estimated size aloft.
The Jun 17, 2026 convective day was bigger than Auburn: the same system put hail over 294 other tracked cities, 134 of them in Illinois. Nearest: Waverly (8 miles west, up to 0.5"); Pawnee (16 miles east, up to 1"); Springfield (19 miles northeast, up to 2").
These maps are stills from Auburn's Jun 17, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.

Reports came from Glenarm — beyond Auburn itself.
Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.
