How May 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.
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 21, 2026 — this storm produced no NEXRAD point detections over May, so there is one map to show, not two.
Where Jun 21, 2026 sits in May's hail record
This was May's 4th recorded hail day, arriving 9 days after the Jun 12, 2026 storm. By severity it ranks 3rd of the 4 storms we have logged here. Radar put the day's largest stone over May at 0.75" — radar-estimated size aloft.
The Jun 21, 2026 convective day was bigger than May: the same system put hail over 415 other tracked cities, 154 of them in Oklahoma. Nearest: Fort Supply (9 miles southeast, up to 1.25"); Fargo (17 miles south, up to 1.5"); Buffalo (22 miles north, up to 1.5").
These maps are stills from May's Jun 21, 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.
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.
The National Weather Service logged no spotter reports for this storm over May. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
What 0.75" hail means for May roofs
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.
