Hail in Aberdeen Jul 24, 2026
Hit 10 days agoBoth radar surfaces caught this storm: NEXRAD logged 0 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 Aberdeen saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
NEXRAD radar signatures
Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

Where Jul 24, 2026 sits in Aberdeen's hail record
This was Aberdeen's 5th recorded hail day, arriving 17 days after the Jul 7, 2026 storm. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over Aberdeen at 4" — the largest NEXRAD radar signature.
The Jul 24, 2026 convective day was bigger than Aberdeen: the same system put hail over 221 other tracked cities, 13 of them in South Dakota. Nearest: Columbia (6 miles northeast, up to 2.5"); Westport (8 miles northwest, up to 4"); Bath (12 miles southeast, up to 1.75").
These maps are stills from Aberdeen's Jul 24, 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 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.

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.
