How Garrison 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 hail size
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 7, 2026 — this storm produced no NEXRAD point detections over Garrison, so there is one map to show, not two.
Where Jun 7, 2026 sits in Garrison's hail record
This was Garrison's 2nd recorded hail day, arriving 17 days after the May 21, 2026 storm. By severity it ranks 4th of the 8 storms we have logged here. Radar put the day's largest stone over Garrison at 0.75" — radar-estimated size aloft.
The Jun 7, 2026 convective day was bigger than Garrison: the same system put hail over 237 other tracked cities, 62 of them in North Dakota. Nearest: Coleharbor (8 miles southeast, up to 0.75"); Zap (28 miles southwest, up to 1.25"); Makoti (28 miles northwest, up to 0.5").
These maps are stills from Garrison's Jun 7, 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.

Reports came from Emmet and White Shield — beyond Garrison itself.
What 0.75" hail means for Garrison 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.
What this storm is worth to a roofer
$2.8M
Potential roof exposure — 235 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
