Independent storm reports filed with the NWS.
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 over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Only the radar-estimated size surface resolved for Apr 14, 2026 — this storm produced no NEXRAD point detections over Pewaukee, so there is one map to show, not two.
This was Pewaukee's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 1 storms we have logged here. Radar put the day's largest stone over Pewaukee at 1.75" — radar-estimated size aloft.
The Apr 14, 2026 convective day was bigger than Pewaukee: the same system put hail over 476 other tracked cities, 94 of them in Wisconsin. Nearest: Colgate (7 miles north, up to 1.75"); Nashotah (8 miles west, up to 1.75"); Brookfield (8 miles east, up to 1.5").
These maps are stills from Pewaukee's Apr 14, 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.
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.

The storm tracked northeast at roughly 10 mph, based on the timing of ground reports.
Hail was reported over 30 minutes, from to .
Reports came from Hartland, Merton, and Sussex — beyond Pewaukee itself.
At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.
