Evidence / storm surfaces
How Gunnison 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.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Only the NEXRAD radar-signature surface resolved for Jul 21, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Jul 21, 2026 sits in Gunnison's hail record.
This was Gunnison's 4th recorded hail day, arriving 50 days after the Jun 1, 2026 storm. By severity it ranks 5th of the 6 storms we have logged here. Radar put the day's largest stone over Gunnison at 0" — radar-estimated size aloft.
The Jul 21, 2026 convective day was bigger than Gunnison: the same system put hail over 703 other tracked cities. Nearest: Crumrod (9 miles northwest, up to 0"); Elaine (28 miles north, up to 0.5"); Helena (44 miles north, up to 0.5").
These maps are stills. In the app this date is one of 6 Gunnison 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 Gunnison. 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.
Below the severe threshold
What 0" hail means for Gunnison 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.
