How Rensselaer Falls saw the hail — from two instruments

Feb 25, 2026 · Rensselaer Falls, 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 Rensselaer Falls, NY on Feb 25, 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 0.5"

Only the radar-estimated size surface resolved for Feb 25, 2026 — this storm produced no NEXRAD point detections over Rensselaer Falls, so there is one map to show, not two.

The storm in context

Where Feb 25, 2026 sits in Rensselaer Falls's hail record.

This was Rensselaer Falls's 4th recorded hail day, arriving 8 days after the Feb 17, 2026 storm. By severity it ranks 12th of the 13 storms we have logged here. Radar put the day's largest stone over Rensselaer Falls at 0.5" — radar-estimated size aloft.

The Feb 25, 2026 convective day was bigger than Rensselaer Falls: the same system put hail over 2 other tracked cities, 2 of them in New York. Nearest: Canton (5 miles east, up to 1"); Gouverneur (21 miles south, up to 0.5").

These maps are stills. In the app this date is one of 13 Rensselaer Falls 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.

No ground reports were filed with the National Weather Service for this storm over Rensselaer Falls. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.

Below the severe threshold

What 0.5" hail means for Rensselaer Falls 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.

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 Aug 3, 2026.
