Evidence / storm surfaces
How Winner saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
The storm in context
Where Aug 6, 2026 sits in Winner's hail record.
This was Winner's 12th recorded hail day, arriving 7 days after the Jul 30, 2026 storm. By severity it ranks 15th of the 15 storms we have logged here. Radar put the day's largest stone over Winner at 0.5" — radar-estimated size aloft.
The Aug 6, 2026 convective day was bigger than Winner: the same system put hail over 461 other tracked cities, 27 of them in South Dakota. Nearest: Gregory (14 miles southeast, up to 0.5"); Herrick (34 miles southeast, up to 0.75"); Bonesteel (39 miles southeast, up to 0.75").

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 Winner, 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 Winner 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.

What this storm is worth to a roofer.
Potential roof exposure

Potential roof exposure — 43 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
August 2028
Claims from this storm can typically be filed until around August 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
