Evidence / storm surfaces
How Fredonia 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 Oct 20, 2026 — this storm produced no NEXRAD point detections over Fredonia, so there is one map to show, not two.
The storm in context
Where Oct 20, 2026 sits in Fredonia's hail record.
This was Fredonia's 6th recorded hail day, arriving 50 days after the Aug 31, 2026 storm. By severity it ranks 6th of the 6 storms we have logged here. Radar put the day's largest stone over Fredonia at 0.5" — radar-estimated size aloft.
The Oct 20, 2026 convective day was bigger than Fredonia: the same system put hail over 19 other tracked cities, 18 of them in Arizona. Nearest: North Rim (68 miles southeast, up to 0.5"); Grand Canyon (73 miles southeast, up to 0.5"); Chino Valley (148 miles south, up to 0.75").

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 Fredonia, 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 Fredonia 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.
