Hail in Max Jun 29, 2026
Hit 35 days agoBoth radar surfaces caught this storm: NEXRAD logged 41 hail signatures up to 4", and the radar-estimated size reached 2.5" aloft. At 4" — softball or larger — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

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.

Where Jun 29, 2026 sits in Max's hail record
This was Max's 4th recorded hail day, arriving 1 day after the Jun 28, 2026 storm. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Max at 4" — the largest NEXRAD radar signature.
The Jun 29, 2026 convective day was bigger than Max: the same system put hail over 702 other tracked cities, 96 of them in North Dakota. Nearest: Douglas (5 miles west, up to 4"); Sawyer (17 miles northeast, up to 4"); Garrison (19 miles south, up to 4").
These maps are stills from Max's Jun 29, 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 4" hail means for Max roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.

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.
