Both radar surfaces caught this storm: NEXRAD logged 2 hail signatures up to 2.5", and the radar-estimated size reached 0.75" aloft. At 2.5" — baseball — 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 Vermont's 3rd recorded hail day, arriving 22 days after the Mar 26, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Vermont at 2.5" — the largest NEXRAD radar signature.
The Apr 17, 2026 convective day was bigger than Vermont: the same system put hail over 1,016 other tracked cities, 101 of them in Illinois. Nearest: Ipava (9 miles northeast, up to 2.5"); Macomb (13 miles northwest, up to 1"); Browning (14 miles south, up to 3").
These maps are stills from Vermont'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 Astoria and Table Grove — beyond Vermont itself.
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.
