How Rensselaer Falls saw the hail — from two instruments

Apr 6, 2026 · Rensselaer Falls, NY

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.

Radar-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Rensselaer Falls, NY on Apr 6, 2026 Estimated size field

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.

Max size 1.75"

Only the radar-estimated size surface resolved for Apr 6, 2026 — this storm produced no NEXRAD point detections over Rensselaer Falls, so there is one map to show, not two.

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 Rensselaer Falls, 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.

High damage potential

What 1.75" hail means for Rensselaer Falls roofs.

Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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.
