How Winthrop 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.
Radar-estimated hail size
Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.

Only the radar-estimated size surface resolved for May 24, 2026 — this storm produced no NEXRAD point detections over Winthrop, so there is one map to show, not two.
Where May 24, 2026 sits in Winthrop's hail record
This was Winthrop's 3rd recorded hail day, arriving 6 days after the May 18, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Winthrop at 0.75" — radar-estimated size aloft.
The May 24, 2026 convective day was bigger than Winthrop: the same system put hail over 200 other tracked cities, 33 of them in Minnesota. Nearest: Gibbon (8 miles southwest, up to 0.75"); Gaylord (12 miles southeast, up to 0.75"); Buffalo Lake (12 miles northwest, up to 0.75").
These maps are stills from Winthrop's May 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 people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.

What 0.75" hail means for Winthrop roofs
Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.
What this storm is worth to a roofer

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 2, 2026.
