The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Only the radar-estimated size surface resolved for Jun 19, 2026 — this storm produced no NEXRAD point detections over Osseo, so there is one map to show, not two.
This was Osseo's 9th recorded hail day, arriving 9 days after the Jun 10, 2026 storm. By severity it ranks 2nd of the 9 storms we have logged here. Radar put the day's largest stone over Osseo at 1" — radar-estimated size aloft.
The Jun 19, 2026 convective day was bigger than Osseo: the same system put hail over 339 other tracked cities, 26 of them in Wisconsin. Nearest: Fall Creek (11 miles north, up to 0.75"); Augusta (15 miles north, up to 0.75"); Eau Claire (19 miles west, up to 0.75").
These maps are stills from Osseo's Jun 19, 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.
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 Augusta — beyond Osseo itself.
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.
