Evidence / storm surfaces
How Three Lakes saw the hail — from two instruments
Jul 27, 2026 · Three Lakes, 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.
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.
Max size
1.5"
Only the radar-estimated size surface resolved for Jul 27, 2026 — this storm produced no NEXRAD point detections over Three Lakes, so there is one map to show, not two.
The storm in context
Where Jul 27, 2026 sits in Three Lakes's hail record.
This was Three Lakes's 2nd recorded hail day, arriving 71 days after the May 17, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Three Lakes at 1.5" — radar-estimated size aloft.
The Jul 27, 2026 convective day was bigger than Three Lakes: the same system put hail over 803 other tracked cities, 128 of them in Wisconsin. Nearest: Rhinelander (10 miles southwest, up to 1.5"); Eagle River (13 miles northwest, up to 1.75"); Argonne (13 miles southeast, up to 1.5").

High damage potential
What 1.5" hail means for Three Lakes roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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 3, 2026.
