Hail in Buffalo · Sep 12, 2026
Hit 2 days ago
The estimated-size surface reached 2.5" aloft; NEXRAD logged no point detections over Buffalo that day. At 2.5" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Buffalo saw the hail — from two instruments
Sep 12, 2026 · Buffalo, OK
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 Surface resolved
Estimated size field 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
2.5"
Only the radar-estimated size surface resolved for Sep 12, 2026 — this storm produced no NEXRAD point detections over Buffalo, so there is one map to show, not two.
The storm in context
Where Sep 12, 2026 sits in Buffalo's hail record.
This was Buffalo's 12th recorded hail day, arriving 17 days after the Aug 26, 2026 storm. By severity it ranks 1st of the 12 storms we have logged here. Radar put the day's largest stone over Buffalo at 2.5" — radar-estimated size aloft.
The Sep 12, 2026 convective day was bigger than Buffalo: the same system put hail over 354 other tracked cities, 66 of them in Oklahoma. Nearest: Rosston (15 miles northwest, up to 0.75"); May (18 miles south, up to 0.5"); Laverne (20 miles southwest, up to 1.5").
These maps are stills. In the app this date is one of 12 Buffalo 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 2.5" hail means for Buffalo 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.
388 homes × $12,000 avg. claim
Potential roof exposure
$4.7M
Potential roof exposure — 388 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 388 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 13, 2026.
