Two ways to read the storm

How De Kalb Junction saw the hail — from two instruments

We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.

Radar-estimated hail-size map of the storm over De Kalb Junction, NY on Mar 31, 2026 — Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

Max size 2"

Only the radar-estimated size surface resolved for Mar 31, 2026 — this storm produced no NEXRAD point detections over De Kalb Junction, so there is one map to show, not two.

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.

Nobody on the ground filed a report over De Kalb Junction for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.

Severe, roof-replacing hail

What 2" hail means for De Kalb Junction roofs

Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.
