Evidence / storm surfaces
How Lisbon saw the hail — from two instruments
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.
Estimated size field 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.
Only the radar-estimated size surface resolved for Sep 12, 2026 — this storm produced no NEXRAD point detections over Lisbon, so there is one map to show, not two.
The storm in context
Where Sep 12, 2026 sits in Lisbon's hail record.
This was Lisbon's 30th recorded hail day, arriving 10 days after the Sep 2, 2026 storm. By severity it ranks 7th of the 30 storms we have logged here. Radar put the day's largest stone over Lisbon at 1" — radar-estimated size aloft.
The Sep 12, 2026 convective day was bigger than Lisbon: the same system put hail over 354 other tracked cities, 2 of them in New York. Nearest: Potsdam (5 miles east, up to 1"); Richville (21 miles south, up to 0.5"); Latrobe (372 miles southwest, up to 0.5").
These maps are stills. In the app this date is one of 30 Lisbon 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
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 Lisbon. 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 Lisbon 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.
Potential roof exposure
$2.7M
Potential roof exposure — 227 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 227 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 $48 on top of the $150 plan.
