Evidence / storm surfaces
How Sanborn saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Only the radar-estimated size surface resolved for Jul 18, 2026 — this storm produced no NEXRAD point detections over Sanborn, so there is one map to show, not two.
The storm in context
Where Jul 18, 2026 sits in Sanborn's hail record.
This was Sanborn's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Sanborn at 0.5" — radar-estimated size aloft.
The Jul 18, 2026 convective day was bigger than Sanborn: the same system put hail over 377 other tracked cities, 45 of them in New York. Nearest: Ransomville (0 miles north, up to 0.5"); Stella Niagara (5 miles west, up to 0.5"); Youngstown (5 miles west, up to 0.5").
These maps are stills. In the app this date is one of 2 Sanborn 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 Sanborn. 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.
Below the severe threshold
What 0.5" hail means for Sanborn roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$5.4M
Potential roof exposure — 451 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 2 jobs
- Illustrative work
- ~$30K
Close just 0.5% of the 451 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
July 2028
Claims from this storm can typically be filed until around July 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 $95 on top of the $150 plan.
