How Wales saw the hail — from two instruments
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.
Radar-estimated hail size
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

Only the radar-estimated size surface resolved for Jul 27, 2026 — this storm produced no NEXRAD point detections over Wales, so there is one map to show, not two.
Where Jul 27, 2026 sits in Wales's hail record
This was Wales's 2nd recorded hail day, arriving 103 days after the Apr 15, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Wales at 1" — radar-estimated size aloft.
The Jul 27, 2026 convective day was bigger than Wales: the same system put hail over 803 other tracked cities, 128 of them in Wisconsin. Nearest: Dousman (5 miles west, up to 1"); Mukwonago (7 miles south, up to 1.75"); Nashotah (7 miles north, up to 1").
These maps are stills from Wales's Jul 27, 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.

Reports came from Delafield — beyond Wales itself.
What 1" hail means for Wales roofs
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.
What this storm is worth to a roofer
$136M
Potential roof exposure — 11,368 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Other storms in Wales
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.
