How Knox City 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.
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 May 18, 2026 — this storm produced no NEXRAD point detections over Knox City, so there is one map to show, not two.

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 Knox City. 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.
What 0.5" hail means for Knox City roofs
Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.
