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.
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 Jul 27, 2026 — this storm produced no NEXRAD point detections over Greenville, so there is one map to show, not two.
This was Greenville's 3rd recorded hail day, arriving 26 days after the Jul 1, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Greenville at 1.5" — radar-estimated size aloft.
The Jul 27, 2026 convective day was bigger than Greenville: the same system put hail over 803 other tracked cities, 128 of them in Wisconsin. Nearest: Appleton (6 miles northeast, up to 1.75"); Neenah (7 miles south, up to 1.25"); Hortonville (7 miles west, up to 1.25").
These maps are stills from Greenville's Jul 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.
“A tornado... preliminarily EF-3 with estimated winds up to 140 mph... developed 2 miles WNW of Appleton and tracked southward into Fox Crossing and Menasha with damage (GRB)”
— NOAA / SPC storm report
Reports came from Appleton — beyond Greenville 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.
