Severity
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.
Largest radar-indicated size — a signal of damage potential, not confirmation.
How many homes sit inside the storm's footprint.

Evidence / storm surfaces
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.
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.
Only the radar-estimated size surface resolved for Sep 7, 2026 — this storm produced no NEXRAD point detections over Trenton, so there is one map to show, not two.
The storm in context
This was Trenton's 8th recorded hail day, arriving 13 days after the Aug 25, 2026 storm. By severity it ranks 2nd of the 8 storms we have logged here. Radar put the day's largest stone over Trenton at 1" — radar-estimated size aloft.
The Sep 7, 2026 convective day was bigger than Trenton: the same system put hail over 163 other tracked cities, 6 of them in Nebraska. Nearest: Culbertson (9 miles southeast, up to 1.25"); Atwood (13 miles southwest, up to 0.75"); Mc Donald (17 miles southwest, up to 0.5").
These maps are stills. In the app this date is one of 8 Trenton 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
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.

Damage-capable hail signal
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
Potential roof exposure
$2.6M
Potential roof exposure — 213 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 213 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 $45 on top of the $150 plan.
