Evidence / storm surfaces
How Shepherd saw the hail — from two instruments
Jul 15, 2026 · Shepherd, MT
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
Estimated size field 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
0.75"
Only the radar-estimated size surface resolved for Jul 15, 2026 — this storm produced no NEXRAD point detections over Shepherd, so there is one map to show, not two.
The storm in context
Where Jul 15, 2026 sits in Shepherd's hail record.
This was Shepherd's 3rd recorded hail day, arriving 10 days after the Jul 5, 2026 storm. By severity it ranks 2nd of the 5 storms we have logged here. Radar put the day's largest stone over Shepherd at 0.75" — radar-estimated size aloft.
The Jul 15, 2026 convective day was bigger than Shepherd: the same system put hail over 114 other tracked cities, 8 of them in Montana. Nearest: Worden (15 miles east, up to 0.75"); Huntley (15 miles south, up to 0.75"); Acton (18 miles west, up to 1").
These maps are stills. In the app this date is one of 5 Shepherd 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.

Near the severe threshold
What 0.75" hail means for Shepherd 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.

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.
