Evidence / storm surfaces
How Keystone saw the hail — from two instruments
Jun 21, 2026 · Keystone, 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.
Max size
1.5"
Only the radar-estimated size surface resolved for Jun 21, 2026 — this storm produced no NEXRAD point detections over Keystone, so there is one map to show, not two.
The storm in context
Where Jun 21, 2026 sits in Keystone's hail record.
This was Keystone's 2nd recorded hail day, arriving 22 days after the May 30, 2026 storm. By severity it ranks 1st of the 7 storms we have logged here. Radar put the day's largest stone over Keystone at 1.5" — radar-estimated size aloft.
The Jun 21, 2026 convective day was bigger than Keystone: the same system put hail over 415 other tracked cities, 21 of them in Nebraska. Nearest: Paxton (17 miles southeast, up to 1.25"); Ogallala (18 miles south, up to 0.75"); Arthur (21 miles north, up to 1.5").
These maps are stills. In the app this date is one of 7 Keystone 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 Keystone 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 6, 2026.
