Hail in La Crosse May 17, 2026
Both radar surfaces caught this storm: NEXRAD logged 0 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 La Crosse 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 May 17, 2026 sits in La Crosse's hail record
This was La Crosse's 5th recorded hail day, arriving 21 days after the Apr 26, 2026 storm. By severity it ranks 2nd of the 10 storms we have logged here. Radar put the day's largest stone over La Crosse at 4" — the largest NEXRAD radar signature.
The May 17, 2026 convective day was bigger than La Crosse: the same system put hail over 894 other tracked cities, 134 of them in Kansas. Nearest: Bison (9 miles southeast, up to 2.5"); Otis (13 miles east, up to 2.5"); Alexander (13 miles southwest, up to 2.5").
These maps are stills from La Crosse's May 17, 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 La Crosse 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.
