Evidence / storm surfaces
How Shelley saw the hail — from two instruments
Sep 17, 2026 · Shelley, ID
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-estimated hail size Surface resolved
Map image is still rendering for this surface.
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.
Max size
1.25"
Only the radar-estimated size surface resolved for Sep 17, 2026 — this storm produced no NEXRAD point detections over Shelley, so there is one map to show, not two.
The storm in context
Where Sep 17, 2026 sits in Shelley's hail record.
This was Shelley's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 1 storms we have logged here. Radar put the day's largest stone over Shelley at 1.25" — radar-estimated size aloft.
The Sep 17, 2026 convective day was bigger than Shelley: the same system put hail over 75 other tracked cities, 21 of them in Idaho. Nearest: Firth (7 miles south, up to 1.5"); Idaho Falls (14 miles northeast, up to 1.25"); Blackfoot (21 miles west, up to 1.5").
These maps are stills. In the app this date is one of 1 Shelley storm date 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.

Damage-capable hail signal
What 1.25" hail means for Shelley roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
4,762 homes × $12,000 avg. claim
Potential roof exposure
$57M
Potential roof exposure — 4,762 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 18, 2026.
