Evidence / storm surfaces
How Willcox saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Only the radar-estimated size surface resolved for Sep 9, 2026 — this storm produced no NEXRAD point detections over Willcox, so there is one map to show, not two.
The storm in context
Where Sep 9, 2026 sits in Willcox's hail record.
This was Willcox's 12th recorded hail day, arriving 30 days after the Aug 10, 2026 storm. By severity it ranks 11th of the 12 storms we have logged here. Radar put the day's largest stone over Willcox at 0.75" — radar-estimated size aloft.
The Sep 9, 2026 convective day was bigger than Willcox: the same system put hail over 71 other tracked cities, 9 of them in Arizona. Nearest: Dragoon (29 miles southwest, up to 0.5"); Saint David (38 miles southwest, up to 0.75"); Tombstone (42 miles southwest, up to 1").
These maps are stills. In the app this date is one of 12 Willcox 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.
No ground reports were filed with the National Weather Service for this storm over Willcox. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Near the severe threshold
What 0.75" hail means for Willcox 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.
