Evidence / storm surfaces
How Edgerton saw the hail — from two instruments
Aug 9, 2026 · Edgerton, WI
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
NEXRAD radar signatures Surface resolved
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

Radar-estimated hail size Surface resolved
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

The storm in context
Where Aug 9, 2026 sits in Edgerton's hail record.
This was Edgerton's 3rd recorded hail day, arriving 60 days after the Jun 10, 2026 storm. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Edgerton at 0.5" — radar-estimated size aloft.
The Aug 9, 2026 convective day was bigger than Edgerton: the same system put hail over 453 other tracked cities, 41 of them in Wisconsin. Nearest: Milton (7 miles south, up to 0.5"); Fort Atkinson (8 miles east, up to 0.5"); Evansville (12 miles southwest, up to 0.5").

Ground reports
What people on the ground reported
1 report filed with the NWS
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.
Wind reports
1 reportBelow the severe threshold
What 0.5" hail means for Edgerton roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

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 Aug 19, 2026.
