Both radar surfaces caught this storm: NEXRAD logged 6 hail signatures up to 1", and the radar-estimated size reached 0.75" aloft.
A tornado was also reported to the National Weather Service during this storm — see the ground reports below.

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 Spring Hill's 4th recorded hail day, arriving 9 days after the Apr 17, 2026 storm. By severity it ranks 2nd of the 6 storms we have logged here. Radar put the day's largest stone over Spring Hill at 1" — the largest NEXRAD radar signature.
The Apr 26, 2026 convective day was bigger than Spring Hill: the same system put hail over 710 other tracked cities, 277 of them in Kansas. Nearest: Olathe (7 miles north, up to 1.75"); Edgerton (8 miles west, up to 1"); Paola (9 miles southwest, up to 1").
These maps are stills from Spring Hill's Apr 26, 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 785 minutes, from to .
Reports came from Hillsdale, Chiles, and Bucyrus — 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.
