Evidence / storm surfaces
How Dunning saw the hail — from two instruments
Aug 20, 2026 · Dunning, NE
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 20, 2026 sits in Dunning's hail record.
This was Dunning's 9th recorded hail day, arriving 3 days after the Aug 17, 2026 storm. By severity it ranks 3rd of the 9 storms we have logged here. Radar put the day's largest stone over Dunning at 1.75" — radar-estimated size aloft.
The Aug 20, 2026 convective day was bigger than Dunning: the same system put hail over 640 other tracked cities, 31 of them in Nebraska. Nearest: Halsey (10 miles northwest, up to 1.75"); Purdum (14 miles north, up to 1.75"); Anselmo (16 miles east, up to 1.25").
These maps are stills. In the app this date is one of 9 Dunning 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 1.75" hail means for Dunning 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 21, 2026.
