Largest hailstone — the top predictor of roof damage.

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.
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.
Only the radar-estimated size surface resolved for Apr 13, 2026 — this storm produced no NEXRAD point detections over Spring Hill, so there is one map to show, not two.
This was Spring Hill's 2nd recorded hail day, arriving 34 days after the Mar 10, 2026 storm. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over Spring Hill at 1" — radar-estimated size aloft.
The Apr 13, 2026 convective day was bigger than Spring Hill: the same system put hail over 467 other tracked cities, 32 of them in Kansas. Nearest: Edgerton (8 miles west, up to 1"); Bucyrus (11 miles northeast, up to 0.75"); Cleveland (14 miles east, up to 1").
These maps are stills from Spring Hill's Apr 13, 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.

Hail was reported over 28 minutes, from to .
Reports came from Chiles and Hillsdale — beyond Spring Hill 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.
