Hail in Aberdeen Jul 25, 2026
Hit 9 days agoBoth radar surfaces caught this storm: NEXRAD logged 1 hail signature up to 2.75", and the radar-estimated size reached 0.5" aloft. At 2.75" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Aberdeen 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 Jul 25, 2026 sits in Aberdeen's hail record
This was Aberdeen's 6th recorded hail day, arriving 1 day after the Jul 24, 2026 storm. By severity it ranks 2nd of the 6 storms we have logged here. Radar put the day's largest stone over Aberdeen at 2.75" — the largest NEXRAD radar signature.
The Jul 25, 2026 convective day was bigger than Aberdeen: the same system put hail over 303 other tracked cities, 102 of them in South Dakota. Nearest: Columbia (6 miles northeast, up to 2"); Bath (12 miles southeast, up to 0.5"); Mina (14 miles southwest, up to 1").
These maps are stills from Aberdeen's Jul 25, 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 2.75" hail means for Aberdeen 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
$96K
Potential roof exposure — 8 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage. Claims from this storm can typically be filed until around July 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.
