Evidence / storm surfaces
How Coalville saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Only the radar-estimated size surface resolved for Sep 22, 2026 — this storm produced no NEXRAD point detections over Coalville, so there is one map to show, not two.
The storm in context
Where Sep 22, 2026 sits in Coalville's hail record.
This was Coalville's 9th recorded hail day, arriving 5 days after the Sep 17, 2026 storm. By severity it ranks 9th of the 9 storms we have logged here. Radar put the day's largest stone over Coalville at 0.5" — radar-estimated size aloft.
The Sep 22, 2026 convective day was bigger than Coalville: the same system put hail over 97 other tracked cities, 5 of them in Utah. Nearest: Evanston (23 miles northeast, up to 0.5"); Ogden (38 miles west, up to 0.75"); Sandy (49 miles southwest, up to 0.75").
These maps are stills. In the app this date is one of 9 Coalville 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 Coalville. 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 0.5" hail means for Coalville 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.
