Evidence / storm surfaces
How Lisbon saw the hail — from two instruments
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.
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.
Only the radar-estimated size surface resolved for Aug 31, 2026 — this storm produced no NEXRAD point detections over Lisbon, so there is one map to show, not two.
The storm in context
Where Aug 31, 2026 sits in Lisbon's hail record.
This was Lisbon's 28th recorded hail day, arriving 7 days after the Aug 24, 2026 storm. By severity it ranks 14th of the 30 storms we have logged here. Radar put the day's largest stone over Lisbon at 1" — radar-estimated size aloft.
The Aug 31, 2026 convective day was bigger than Lisbon: the same system put hail over 40 other tracked cities, 4 of them in New York. Nearest: Chase Mills (8 miles northeast, up to 0.5"); Edwards (28 miles south, up to 0.5"); Gouverneur (29 miles south, 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.
For this storm over Lisbon, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
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
$288K
Potential roof exposure — 24 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
August 2028
Claims from this storm can typically be filed until around August 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 $5 on top of the $150 plan.
