Evidence / storm surfaces

How White River saw the hail — from two instruments

Aug 24, 2026 · White River, SD

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
Radar-estimated hail-size map of the storm over White River, SD on Aug 24, 2026 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 1.5"

Only the radar-estimated size surface resolved for Aug 24, 2026 — this storm produced no NEXRAD point detections over White River, so there is one map to show, not two.

The storm in context

Where Aug 24, 2026 sits in White River's hail record.

This was White River's 12th recorded hail day, arriving 6 days after the Aug 18, 2026 storm. By severity it ranks 4th of the 13 storms we have logged here. Radar put the day's largest stone over White River at 1.5" — radar-estimated size aloft.

The Aug 24, 2026 convective day was bigger than White River: the same system put hail over 232 other tracked cities, 45 of them in South Dakota. Nearest: Wood (17 miles southeast, up to 0.5"); Okaton (22 miles north, up to 1.25"); Murdo (24 miles north, up to 2.5").

These maps are stills. In the app this date is one of 13 White River 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.

High damage potential

What 1.5" hail means for White River roofs.

Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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 Aug 28, 2026.
