Hail in Osceola Jun 11, 2026
The radar-estimated size surface caught this storm, reaching 2.75" aloft. NEXRAD logged no point detections over Osceola this day. At 2.75" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Osceola 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 Jun 11, 2026 — this storm produced no NEXRAD point detections over Osceola, so there is one map to show, not two.
Where Jun 11, 2026 sits in Osceola's hail record
This was Osceola's 7th recorded hail day, arriving 1 day after the Jun 10, 2026 storm. By severity it ranks 1st of the 9 storms we have logged here. Radar put the day's largest stone over Osceola at 2.75" — radar-estimated size aloft.
The Jun 11, 2026 convective day was bigger than Osceola: the same system put hail over 648 other tracked cities, 147 of them in Iowa. Nearest: Grand River (9 miles southwest, up to 2.75"); Weldon (10 miles east, up to 2.75"); Ellston (10 miles west, up to 2.5").
These maps are stills from Osceola's Jun 11, 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.
Hail reports
1 reportWhat 2.75" hail means for Osceola 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.
