Evidence / storm surfaces
How Custer 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 20, 2026 — this storm produced no NEXRAD point detections over Custer, so there is one map to show, not two.
The storm in context
Where Sep 20, 2026 sits in Custer's hail record.
This was Custer's 22nd recorded hail day, arriving 1 day after the Sep 19, 2026 storm. By severity it ranks 20th of the 22 storms we have logged here. Radar put the day's largest stone over Custer at 0.5" — radar-estimated size aloft.
The Sep 20, 2026 convective day was bigger than Custer: the same system put hail over 253 other tracked cities. Nearest: Lingle (101 miles south, up to 0.5"); Sidney (171 miles south, up to 1"); Haxtun (218 miles south, up to 1.5").
These maps are stills. In the app this date is one of 22 Custer 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.
For this storm over Custer, 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 Custer 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
$72K
Potential roof exposure — 6 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.
