Evidence / storm surfaces
How Minnesota City 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 Sep 1, 2026 — this storm produced no NEXRAD point detections over Minnesota City, so there is one map to show, not two.
The storm in context
Where Sep 1, 2026 sits in Minnesota City's hail record.
This was Minnesota City's 9th recorded hail day, arriving 14 days after the Aug 18, 2026 storm. By severity it ranks 9th of the 10 storms we have logged here. Radar put the day's largest stone over Minnesota City at 0.5" — radar-estimated size aloft.
The Sep 1, 2026 convective day was bigger than Minnesota City: the same system put hail over 362 other tracked cities, 56 of them in Minnesota. Nearest: Fountain City (5 miles east, up to 0.75"); Winona (10 miles southeast, up to 1.5"); Trempealeau (13 miles east, up to 1.5").

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 Minnesota City. 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 0.5" hail means for Minnesota City 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$1.2M
Potential roof exposure — 98 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
September 2028
Claims from this storm can typically be filed until around September 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $21 on top of the $150 plan.
