Hail in Alliance · Jun 27, 2026
NEXRAD logged 84 hail signatures up to 2.75"; the estimated-size surface reached 2.5" aloft. At 2.75" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Alliance saw the hail — from two instruments
Jun 27, 2026 · Alliance, NE
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
NEXRAD radar signatures Surface resolved
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

Radar-estimated hail size Surface resolved
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

The storm in context
Where Jun 27, 2026 sits in Alliance's hail record.
This was Alliance's 6th recorded hail day, arriving 1 day after the Jun 26, 2026 storm. By severity it ranks 2nd of the 16 storms we have logged here. Radar put the day's largest stone over Alliance at 2.75" — the largest NEXRAD radar signature.
The Jun 27, 2026 convective day was bigger than Alliance: the same system put hail over 587 other tracked cities, 16 of them in Nebraska. Nearest: Hemingford (11 miles north, up to 2.75"); Lakeside (31 miles east, up to 2.5"); Ellsworth (41 miles east, up to 1.75").
These maps are stills. In the app this date is one of 16 Alliance 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.

Severe hail signal
What 2.75" hail means for Alliance roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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.
