Two ways to read the storm

How Custer saw the hail — from two instruments

Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.

Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

Max size 1.75"

Only the radar-estimated size surface resolved for Jul 14, 2026 — this storm produced no NEXRAD point detections over Custer, so there is one map to show, not two.

The storm in context

Where Jul 14, 2026 sits in Custer's hail record

This was Custer's 3rd recorded hail day, arriving 17 days after the Jun 27, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Custer at 1.75" — radar-estimated size aloft.

The Jul 14, 2026 convective day was bigger than Custer: the same system put hail over 130 other tracked cities, 23 of them in Montana. Nearest: Musselshell (24 miles northwest, up to 1.25"); Roundup (37 miles northwest, up to 1.5"); Lavina (52 miles west, up to 3.25").

These maps are stills from Custer's Jul 14, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

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.

Nobody on the ground filed a report over Custer for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.

Widespread claimable damage

What 1.75" hail means for Custer roofs

At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.

What this storm is worth to a roofer

$1.6M

Potential roof exposure — 130 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 130 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

Other storms in Custer

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 surfaces are detections and estimates, not confirmed damage. Last updated Aug 3, 2026.
