How Green Bay saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Radar-estimated hail size
The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Max size
0.75"
Only the radar-estimated size surface resolved for Jun 24, 2026 — this storm produced no NEXRAD point detections over Green Bay, so there is one map to show, not two.
Where Jun 24, 2026 sits in Green Bay's hail record
This was Green Bay's 4th recorded hail day, arriving 71 days after the Apr 14, 2026 storm. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over Green Bay at 0.75" — radar-estimated size aloft.
The Jun 24, 2026 convective day was bigger than Green Bay: the same system put hail over 383 other tracked cities, 66 of them in Wisconsin. Nearest: Pulaski (21 miles west, up to 0.75"); Bonduel (28 miles northwest, up to 0.75"); Gillett (35 miles northwest, up to 1.5").
These maps are stills from Green Bay's Jun 24, 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.

What 0.75" hail means for Green Bay roofs
Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.

ground report
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 surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
