Evidence / storm surfaces
How Gouverneur 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 Apr 21, 2026 — this storm produced no NEXRAD point detections over Gouverneur, so there is one map to show, not two.
The storm in context
Where Apr 21, 2026 sits in Gouverneur's hail record.
This was Gouverneur's 8th recorded hail day, arriving 14 days after the Apr 7, 2026 storm. By severity it ranks 5th of the 19 storms we have logged here. Radar put the day's largest stone over Gouverneur at 0.75" — radar-estimated size aloft.
The Apr 21, 2026 convective day was bigger than Gouverneur: the same system put hail over 24 other tracked cities, 1 of them in New York. Nearest: Richville (8 miles northeast, up to 0.75"); Killbuck (427 miles southwest, up to 0.5"); Richmond (576 miles southwest, up to 0").

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 Gouverneur, 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.
Near the severe threshold
What 0.75" hail means for Gouverneur 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$228K
Potential roof exposure — 19 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
April 2028
Claims from this storm can typically be filed until around April 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
