Evidence / storm surfaces
How Colville saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Aug 22, 2026 — this storm produced no NEXRAD point detections over Colville, so there is one map to show, not two.
The storm in context
Where Aug 22, 2026 sits in Colville's hail record.
This was Colville's 4th recorded hail day, arriving 36 days after the Jul 17, 2026 storm. By severity it ranks 3rd of the 4 storms we have logged here. Radar put the day's largest stone over Colville at 0.75" — radar-estimated size aloft.
The Aug 22, 2026 convective day was bigger than Colville: the same system put hail over 501 other tracked cities, 5 of them in Washington. Nearest: Addy (8 miles southwest, up to 0.5"); Chewelah (15 miles south, up to 0.5"); Hunters (17 miles southwest, up to 0.5").

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.
The National Weather Service logged no spotter reports for this storm over Colville. 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.
Near the severe threshold
What 0.75" hail means for Colville 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.
