Evidence / storm surfaces
How Williams 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.
Estimated size field 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 Aug 3, 2026 — this storm produced no NEXRAD point detections over Williams, so there is one map to show, not two.
The storm in context
Where Aug 3, 2026 sits in Williams's hail record.
This was Williams's 6th recorded hail day, arriving 8 days after the Jul 26, 2026 storm. By severity it ranks 6th of the 6 storms we have logged here. Radar put the day's largest stone over Williams at 0.5" — radar-estimated size aloft.
The Aug 3, 2026 convective day was bigger than Williams: the same system put hail over 172 other tracked cities, 71 of them in Minnesota. Nearest: Salol (33 miles west, up to 0.5"); Wannaska (38 miles west, up to 1"); Roseau (39 miles west, up to 1").

Ground reports
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.
For this storm over Williams, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Below the severe threshold
What 0.5" hail means for Williams roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.
