Hail in Wounded Knee Jun 28, 2026
Hit 36 days agoBoth radar surfaces caught this storm: NEXRAD logged 4 hail signatures up to 4", and the radar-estimated size reached 3" aloft. At 4" — softball or larger — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Wounded Knee saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
NEXRAD radar signatures
The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.

Where Jun 28, 2026 sits in Wounded Knee's hail record
This was Wounded Knee's 4th recorded hail day, arriving 1 day after the Jun 27, 2026 storm. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over Wounded Knee at 4" — the largest NEXRAD radar signature.
The Jun 28, 2026 convective day was bigger than Wounded Knee: the same system put hail over 348 other tracked cities, 42 of them in South Dakota. Nearest: Pine Ridge (5 miles west, up to 4"); Manderson (7 miles north, up to 4"); Batesland (11 miles east, up to 4").
These maps are stills from Wounded Knee'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 4" hail means for Wounded Knee 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.
What this storm is worth to a roofer
$408K
Potential roof exposure — 34 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage. Claims from this storm can typically be filed until around June 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

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.
