Evidence / storm surfaces
How Terreton 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 Aug 22, 2026 — this storm produced no NEXRAD point detections over Terreton, so there is one map to show, not two.

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 Terreton, 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 Terreton 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.

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.
