Evidence / storm surfaces
How Collins saw the hail — from two instruments
Mar 31, 2026 · Collins, NY
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
NEXRAD radar signatures Surface resolved
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.

Radar-estimated hail size Surface resolved
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

The storm in context
Where Mar 31, 2026 sits in Collins's hail record.
This was Collins's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Collins at 4" — the largest NEXRAD radar signature.
The Mar 31, 2026 convective day was bigger than Collins: the same system put hail over 522 other tracked cities, 56 of them in New York. Nearest: Perrysburg (8 miles west, up to 4"); East Otto (10 miles southeast, up to 3.75"); Cattaraugus (10 miles south, up to 4").
These maps are stills. In the app this date is one of 3 Collins 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.

Severe hail signal
What 4" hail means for Collins roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

Roofing exposure
What this storm is worth to a roofer.
400 homes × $12,000 avg. claim
Potential roof exposure
$4.8M
Potential roof exposure — 400 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 400 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window

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 3, 2026.
