Evidence / storm surfaces
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.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Estimated size field 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.
The storm in context
Where Apr 26, 2026 sits in La Crosse's hail record.
This was La Crosse's 4th recorded hail day, arriving 1 day after the Apr 25, 2026 storm. By severity it ranks 4th of the 13 storms we have logged here. Radar put the day's largest stone over La Crosse at 1.5" — the largest NEXRAD radar signature.
The Apr 26, 2026 convective day was bigger than La Crosse: the same system put hail over 710 other tracked cities, 277 of them in Kansas. Nearest: Hays (7 miles north, up to 1.75"); Bison (9 miles southeast, up to 1.25"); Pfeifer (11 miles northeast, up to 1.25").

Ground reports
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.
No ground reports were filed with the National Weather Service for this storm over La Crosse. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
High damage potential
What 1.5" hail means for La Crosse roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.
