Evidence / storm surfaces
How Custer saw the hail — from two instruments
Jul 28, 2026 · Custer, SD
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.
NEXRAD radar signatures Surface resolved
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

Radar-estimated hail size Surface resolved
Estimated size field 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.

The storm in context
Where Jul 28, 2026 sits in Custer's hail record.
This was Custer's 13th recorded hail day, arriving 11 days after the Jul 17, 2026 storm. By severity it ranks 12th of the 20 storms we have logged here. Radar put the day's largest stone over Custer at 1" — the largest NEXRAD radar signature.
The Jul 28, 2026 convective day was bigger than Custer: the same system put hail over 686 other tracked cities, 5 of them in South Dakota. Nearest: Fairburn (31 miles east, up to 1"); Hot Springs (31 miles southeast, up to 1"); Hermosa (32 miles east, up to 1").
These maps are stills. In the app this date is one of 20 Custer 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.

Damage-capable hail signal
What 1" hail means for Custer 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.

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 14, 2026.
