How Milwaukee saw the hail — from two instruments
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
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

Only the radar-estimated size surface resolved for Apr 15, 2026 — this storm produced no NEXRAD point detections over Milwaukee, so there is one map to show, not two.
Where Apr 15, 2026 sits in Milwaukee's hail record
This was Milwaukee's 2nd recorded hail day, arriving 1 day after the Apr 14, 2026 storm. By severity it ranks 3rd of the 4 storms we have logged here. Radar put the day's largest stone over Milwaukee at 0.5" — radar-estimated size aloft.
The Apr 15, 2026 convective day was bigger than Milwaukee: the same system put hail over 425 other tracked cities, 11 of them in Wisconsin. Nearest: Waukesha (24 miles southwest, up to 0.5"); Wales (26 miles west, up to 0.5"); Brodhead (81 miles southwest, up to 0.5").
These maps are stills from Milwaukee's Apr 15, 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 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.

What 0.5" hail means for Milwaukee roofs
Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.
What this storm is worth to a roofer

Other storms in Milwaukee
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.
