Evidence / storm surfaces

How Sidney saw the hail — from two instruments

Sep 20, 2026 · Sidney, 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
Map image is still rendering for this surface.

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"

Only the radar-estimated size surface resolved for Sep 20, 2026 — this storm produced no NEXRAD point detections over Sidney, so there is one map to show, not two.

The storm in context

Where Sep 20, 2026 sits in Sidney's hail record.

This was Sidney's 19th recorded hail day, arriving 30 days after the Aug 21, 2026 storm. By severity it ranks 10th of the 19 storms we have logged here. Radar put the day's largest stone over Sidney at 1" — radar-estimated size aloft.

The Sep 20, 2026 convective day was bigger than Sidney: the same system put hail over 253 other tracked cities, 4 of them in Nebraska. Nearest: Haxtun (47 miles south, up to 1.5"); Fleming (48 miles south, up to 1.75"); Holyoke (56 miles southeast, up to 2").

These maps are stills. In the app this date is one of 19 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.

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.

The National Weather Service logged no spotter reports for this storm over Sidney. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.

Damage-capable hail signal

What 1" hail means for Sidney roofs.

Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure

What this storm is worth to a roofer.

151 homes × $12,000 avg. claim

Potential roof exposure

$1.8M

Potential roof exposure — 151 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Illustrative jobs
1 job

~$15K

Close just 0.5% of the 151 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.

Claim window

September 2028

Claims from this storm can typically be filed until around September 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

Names and phones for every home in the footprint: at most $32 on top of the $150 plan.

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 21, 2026.
