How Max saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
NEXRAD radar signatures
NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

Radar-estimated hail size
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

Where Jun 9, 2026 sits in Max's hail record
This was Max's 2nd recorded hail day, arriving 7 days after the Jun 2, 2026 storm. By severity it ranks 4th of the 4 storms we have logged here. Radar put the day's largest stone over Max at 1.25" — the largest NEXRAD radar signature.
The Jun 9, 2026 convective day was bigger than Max: the same system put hail over 646 other tracked cities, 110 of them in North Dakota. Nearest: Douglas (5 miles west, up to 1.25"); Garrison (19 miles south, up to 1.5"); Coleharbor (24 miles south, up to 1.75").
These maps are stills from Max's Jun 9, 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.

What 1.25" hail means for Max roofs
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.
What this storm is worth to a roofer
$2.5M
Potential roof exposure — 211 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Other storms in Max
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 2, 2026.
