How Gouverneur saw the hail — from two instruments

Apr 3, 2026 · Gouverneur, 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 Gouverneur, NY on Apr 3, 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 Apr 3, 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 3, 2026 sits in Gouverneur's hail record.

This was Gouverneur's 5th recorded hail day, arriving 2 days after the Apr 1, 2026 storm. By severity it ranks 7th 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 3, 2026 convective day was bigger than Gouverneur: the same system put hail over 367 other tracked cities, 1 of them in New York. Nearest: De Kalb Junction (15 miles north, up to 0.5"); Ravenna (366 miles southwest, up to 0"); Navarre (398 miles southwest, up to 0.75").

These maps are stills. In the app this date is one of 19 Gouverneur 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.

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.

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 Sep 1, 2026.
