How Hayward 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 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 26, 2026 — this storm produced no NEXRAD point detections over Hayward, so there is one map to show, not two.
Where May 26, 2026 sits in Hayward's hail record
This was Hayward's 2nd recorded hail day, arriving 39 days after the Apr 17, 2026 storm. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Hayward at 1" — radar-estimated size aloft.
The May 26, 2026 convective day was bigger than Hayward: the same system put hail over 259 other tracked cities, 12 of them in Wisconsin. Nearest: Stone Lake (16 miles southwest, up to 0.5"); Springbrook (17 miles west, up to 0.75"); Exeland (19 miles southwest, up to 0.5").
These maps are stills from Hayward's May 26, 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.

Reports came from Little Round Lake — beyond Hayward itself.
What 1" hail means for Hayward roofs
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.
