Evidence / storm surfaces
How Columbus 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 6, 2026 — this storm produced no NEXRAD point detections over Columbus, so there is one map to show, not two.
The storm in context
Where Sep 6, 2026 sits in Columbus's hail record.
This was Columbus's 6th recorded hail day, arriving 42 days after the Jul 26, 2026 storm. By severity it ranks 4th of the 6 storms we have logged here. Radar put the day's largest stone over Columbus at 0.75" — radar-estimated size aloft.
The Sep 6, 2026 convective day was bigger than Columbus: the same system put hail over 608 other tracked cities, 49 of them in Montana. Nearest: Reed Point (18 miles west, up to 0.5"); Billings (36 miles east, up to 2.25"); Broadview (42 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.
For this storm over Columbus, 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.
Near the severe threshold
What 0.75" hail means for Columbus roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$612K
Potential roof exposure — 51 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.
