Evidence / storm surfaces
How Martin 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.
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.
Only the radar-estimated size surface resolved for Sep 7, 2026 — this storm produced no NEXRAD point detections over Martin, so there is one map to show, not two.
The storm in context
Where Sep 7, 2026 sits in Martin's hail record.
This was Martin's 16th recorded hail day, arriving 11 days after the Aug 27, 2026 storm. By severity it ranks 15th of the 16 storms we have logged here. Radar put the day's largest stone over Martin at 0.5" — radar-estimated size aloft.
The Sep 7, 2026 convective day was bigger than Martin: the same system put hail over 163 other tracked cities, 19 of them in South Dakota. Nearest: Allen (7 miles north, up to 0.5"); Wanblee (28 miles northeast, up to 0.5"); Long Valley (29 miles northeast, up to 0.5").

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.
The National Weather Service logged no spotter reports for this storm over Martin. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Below the severe threshold
What 0.5" hail means for Martin 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
$972K
Potential roof exposure — 81 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 $17 on top of the $150 plan.
