Evidence / storm surfaces
How Bristol saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Jul 27, 2026 — this storm produced no NEXRAD point detections over Bristol, so there is one map to show, not two.
The storm in context
Where Jul 27, 2026 sits in Bristol's hail record.
This was Bristol's 3rd recorded hail day, arriving 18 days after the Jul 9, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Bristol at 1.5" — radar-estimated size aloft.
The Jul 27, 2026 convective day was bigger than Bristol: the same system put hail over 803 other tracked cities, 128 of them in Wisconsin. Nearest: Salem (5 miles west, up to 1.75"); Kenosha (7 miles south, up to 1.5"); Antioch (7 miles south, up to 1").

Ground reports
What people on the ground reported
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 reports
1 reportHigh damage potential
What 1.5" hail means for Bristol roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.
