Hail in Horicon · Sep 3, 2026
Hit 9 days ago
The estimated-size surface reached 2.5" aloft; NEXRAD logged no point detections over Horicon that day. At 2.5" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Horicon saw the hail — from two instruments
Sep 3, 2026 · Horicon, WI
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 Surface resolved
Estimated size field 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.
Max size
2.5"
Only the radar-estimated size surface resolved for Sep 3, 2026 — this storm produced no NEXRAD point detections over Horicon, so there is one map to show, not two.
The storm in context
Where Sep 3, 2026 sits in Horicon's hail record.
This was Horicon's 4th recorded hail day, arriving 38 days after the Jul 27, 2026 storm. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Horicon at 2.5" — radar-estimated size aloft.
The Sep 3, 2026 convective day was bigger than Horicon: the same system put hail over 494 other tracked cities, 71 of them in Wisconsin. Nearest: Mayville (5 miles east, up to 2.75"); Burnett (5 miles west, up to 1.75"); Iron Ridge (7 miles south, up to 2.75").
These maps are stills. In the app this date is one of 4 Horicon storm dates on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.

Severe hail signal
What 2.5" hail means for Horicon roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

Roofing exposure
What this storm is worth to a roofer.
4,887 homes × $12,000 avg. claim
Potential roof exposure
$59M
Potential roof exposure — 4,887 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 4, 2026.
