Largest hailstone — the top predictor of roof damage.
How many homes sit inside the storm's footprint.
Independent storm reports filed with the NWS.
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
This was Osage City's 2nd recorded hail day, arriving 4 days after the Apr 13, 2026 storm. By severity it ranks 2nd of the 12 storms we have logged here. Radar put the day's largest stone over Osage City at 1.75" — the largest NEXRAD radar signature.
The Apr 17, 2026 convective day was bigger than Osage City: the same system put hail over 1,016 other tracked cities, 144 of them in Kansas. Nearest: Burlingame (7 miles north, up to 1"); Reading (8 miles west, up to 1.75"); Scranton (8 miles east, up to 1.25").
These maps are stills from Osage City's Apr 17, 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 Olivet — beyond Osage City itself.
At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.
