Evidence / storm surfaces
How Red Wing 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 signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
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.
The storm in context
Where May 17, 2026 sits in Red Wing's hail record.
This was Red Wing's 5th recorded hail day, arriving 24 days after the Apr 23, 2026 storm. By severity it ranks 7th of the 8 storms we have logged here. Radar put the day's largest stone over Red Wing at 0" — radar-estimated size aloft.
The May 17, 2026 convective day was bigger than Red Wing: the same system put hail over 894 other tracked cities, 91 of them in Minnesota. Nearest: Goodhue (12 miles southwest, up to 1"); Millville (17 miles southeast, up to 0"); Mazeppa (21 miles south, up to 1").
These maps are stills. In the app this date is one of 8 Red Wing storm dates on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.
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.
No ground reports were filed with the National Weather Service for this storm over Red Wing. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Below the severe threshold
What 0" hail means for Red Wing 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.
