Evidence / storm surfaces

How Sidney saw the hail — from two instruments

Aug 21, 2026 · Sidney, NE

Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.

Radar-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Sidney, NE on Aug 21, 2026 Estimated size field

Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

Max size 2"

Only the radar-estimated size surface resolved for Aug 21, 2026 — this storm produced no NEXRAD point detections over Sidney, so there is one map to show, not two.

The storm in context

Where Aug 21, 2026 sits in Sidney's hail record.

This was Sidney's 18th recorded hail day, arriving 11 days after the Aug 10, 2026 storm. By severity it ranks 1st of the 18 storms we have logged here. Radar put the day's largest stone over Sidney at 2" — radar-estimated size aloft.

The Aug 21, 2026 convective day was bigger than Sidney: the same system put hail over 659 other tracked cities, 38 of them in Nebraska. Nearest: Peetz (7 miles south, up to 1.75"); Padroni (15 miles southwest, up to 1.75"); Dix (16 miles west, up to 2").

These maps are stills. In the app this date is one of 18 Sidney 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.

How the storm moved

Timing and place names from NOAA ground reports

Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.

Reports came from Lorenzo — beyond Sidney itself.

Severe hail signal

What 2" hail means for Sidney 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.

Roofing exposure

What this storm is worth to a roofer.

406 homes × $12,000 avg. claim

Potential roof exposure

$4.9M

Potential roof exposure — 406 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

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 22, 2026.
