Hail in Norris Jun 28, 2026
Hit 36 days agoBoth radar surfaces caught this storm: NEXRAD logged 1 hail signature up to 2.5", and the radar-estimated size reached 2.5" aloft. At 2.5" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Norris 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.

Where Jun 28, 2026 sits in Norris's hail record
This was Norris's 2nd recorded hail day, arriving 67 days after the Apr 22, 2026 storm. By severity it ranks 3rd of the 4 storms we have logged here. Radar put the day's largest stone over Norris at 2.5" — radar-estimated size aloft.
The Jun 28, 2026 convective day was bigger than Norris: the same system put hail over 348 other tracked cities, 42 of them in South Dakota. Nearest: Long Valley (13 miles west, up to 2.5"); Parmelee (14 miles southeast, up to 2.5"); White River (18 miles east, up to 4").
These maps are stills from Norris's Jun 28, 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 2.5" hail means for Norris 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 Norris
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.
