Evidence / storm surfaces
How Carpenter 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 May 9, 2026 sits in Carpenter's hail record.
This was Carpenter's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 6th of the 6 storms we have logged here. Radar put the day's largest stone over Carpenter at 0.75" — the largest NEXRAD radar signature.
The May 9, 2026 convective day was bigger than Carpenter: the same system put hail over 268 other tracked cities, 3 of them in Wyoming. Nearest: Pine Bluffs (5 miles east, up to 1.5"); Bushnell (27 miles east, up to 1.5"); Cheyenne (40 miles west, 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 Carpenter. 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 Carpenter 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.
