Both radar surfaces caught this storm: NEXRAD logged 28 hail signatures up to 2.25", and the radar-estimated size reached 0.75" aloft. At 2.25" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.
A tornado was also reported to the National Weather Service during this storm — see the ground reports below.

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 Seymour's 2nd recorded hail day, arriving 36 days after the Mar 22, 2026 storm. By severity it ranks 1st of the 7 storms we have logged here. Radar put the day's largest stone over Seymour at 2.25" — the largest NEXRAD radar signature.
The Apr 27, 2026 convective day was bigger than Seymour: the same system put hail over 1,188 other tracked cities, 125 of them in Indiana. Nearest: Crothersville (10 miles south, up to 1.25"); Brownstown (11 miles southwest, up to 2.25"); Austin (12 miles southeast, up to 1").
These maps are stills from Seymour's Apr 27, 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.
