Hail in Aberdeen · Jul 25, 2026
NEXRAD logged 1 hail signature up to 2.75"; the estimated-size surface reached 0.5" aloft. At 2.75" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Aberdeen saw the hail — from two instruments
Jul 25, 2026 · Aberdeen, SD
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.

The storm in context
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 7 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: Mina (5 miles west, up to 1"); Mansfield (12 miles southwest, up to 1"); Ipswich (15 miles west, up to 1").

Severe hail signal
What 2.75" hail means for Aberdeen roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 25, 2026.
