Evidence / storm surfaces
How Capitol 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.
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
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.
The storm in context
Where Jul 28, 2026 sits in Capitol's hail record.
This was Capitol's 4th recorded hail day, arriving 12 days after the Jul 16, 2026 storm. By severity it ranks 5th of the 6 storms we have logged here. Radar put the day's largest stone over Capitol at 0.75" — the largest NEXRAD radar signature.
The Jul 28, 2026 convective day was bigger than Capitol: the same system put hail over 686 other tracked cities, 1 of them in Montana. Nearest: Camp Crook (7 miles north, up to 0.75"); Hermosa (117 miles southeast, up to 1"); Custer (119 miles south, up to 1").

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 Capitol, 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.
Near the severe threshold
What 0.75" hail means for Capitol 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.
