Hail in Shepherd · Sep 6, 2026
Hit 6 days ago
The estimated-size surface reached 2.25" aloft; NEXRAD logged no point detections over Shepherd that day. At 2.25" — tennis ball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Shepherd saw the hail — from two instruments
Sep 6, 2026 · Shepherd, MT
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-estimated hail size Surface resolved
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.
Max size
2.25"
Only the radar-estimated size surface resolved for Sep 6, 2026 — this storm produced no NEXRAD point detections over Shepherd, so there is one map to show, not two.
The storm in context
Where Sep 6, 2026 sits in Shepherd's hail record.
This was Shepherd's 5th recorded hail day, arriving 52 days after the Jul 16, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Shepherd at 2.25" — radar-estimated size aloft.
The Sep 6, 2026 convective day was bigger than Shepherd: the same system put hail over 608 other tracked cities, 49 of them in Montana. Nearest: Huntley (15 miles south, up to 2.25"); Worden (15 miles east, up to 1.25"); Broadview (17 miles west, up to 0.5").

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.
Hail reports
1 reportSevere hail signal
What 2.25" hail means for Shepherd roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 7, 2026.
