Evidence / storm surfaces

How Canton saw the hail — from two instruments

Oct 10, 2026 · Canton, NY

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
Radar-estimated hail-size map of the storm over Canton, NY on Oct 10, 2026 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.

Max size 0.75"

Only the radar-estimated size surface resolved for Oct 10, 2026 — this storm produced no NEXRAD point detections over Canton, so there is one map to show, not two.

The storm in context

Where Oct 10, 2026 sits in Canton's hail record.

This was Canton's 15th recorded hail day, arriving 15 days after the Sep 25, 2026 storm. By severity it ranks 5th of the 15 storms we have logged here. Radar put the day's largest stone over Canton at 0.75" — radar-estimated size aloft.

The Oct 10, 2026 convective day was bigger than Canton: the same system put hail over 10 other tracked cities, 1 of them in New York. Nearest: De Kalb Junction (8 miles southwest, up to 0.5"); Sylvania (893 miles south, up to 0.5"); Jackson (1771 miles west, up to 0.5").

These maps are stills. In the app this date is one of 15 Canton 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 Canton. 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.

Near the severe threshold

What 0.75" hail means for Canton roofs.

A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

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 Oct 11, 2026.
