The radar-estimated size surface caught this storm, reaching 2" aloft. NEXRAD logged no point detections over Osawatomie this day. At 2" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

Largest hailstone — the top predictor of roof damage.

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 Apr 15, 2026 — this storm produced no NEXRAD point detections over Osawatomie, so there is one map to show, not two.
This was Osawatomie's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Osawatomie at 2" — radar-estimated size aloft.
The Apr 15, 2026 convective day was bigger than Osawatomie: the same system put hail over 425 other tracked cities, 34 of them in Kansas. Nearest: Greeley (5 miles west, up to 1.75"); Paola (14 miles north, up to 1.75"); Mound City (19 miles southeast, up to 0.75").
These maps are stills from Osawatomie's Apr 15, 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.

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.
