How Alliance saw the hail — from two instruments

Jul 6, 2026 · Alliance, 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.

The storm in context

Where Jul 6, 2026 sits in Alliance's hail record.

This was Alliance's 8th recorded hail day, arriving 3 days after the Jul 3, 2026 storm. By severity it ranks 4th of the 16 storms we have logged here. Radar put the day's largest stone over Alliance at 3" — the largest NEXRAD radar signature.

The Jul 6, 2026 convective day was bigger than Alliance: the same system put hail over 832 other tracked cities, 19 of them in Nebraska. Nearest: Hemingford (11 miles north, up to 1.75"); Crawford (29 miles northwest, up to 0.5"); Lakeside (31 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.

Ground reports

What people on the ground reported

No reports filed with the NWS

These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.

Nobody on the ground filed a report over Alliance for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.

Severe hail signal

What 3" 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.
