Evidence / storm surfaces
How Colome saw the hail — from two instruments
Aug 11, 2026 · Colome, 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
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.

The storm in context
Where Aug 11, 2026 sits in Colome's hail record.
This was Colome's 4th recorded hail day, arriving 42 days after the Jun 30, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Colome at 1.5" — radar-estimated size aloft.
The Aug 11, 2026 convective day was bigger than Colome: the same system put hail over 1,041 other tracked cities, 44 of them in South Dakota. Nearest: Springview (17 miles south, up to 1.5"); Winner (23 miles northeast, up to 2"); Mills (25 miles southeast, up to 1").
These maps are stills. In the app this date is one of 5 Colome 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 Colome 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 Sep 2, 2026.
