Evidence / storm surfaces
How Elgin saw the hail — from two instruments
Apr 17, 2026 · Elgin, 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.
NEXRAD radar signatures Surface resolved
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

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.

The storm in context
Where Apr 17, 2026 sits in Elgin's hail record.
This was Elgin's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 7th of the 8 storms we have logged here. Radar put the day's largest stone over Elgin at 1" — the largest NEXRAD radar signature.
The Apr 17, 2026 convective day was bigger than Elgin: the same system put hail over 1,016 other tracked cities, 109 of them in Oklahoma. Nearest: Fort Sill (9 miles southwest, up to 1"); Lawton (11 miles southwest, up to 1"); Fletcher (11 miles east, up to 0.5").
These maps are stills. In the app this date is one of 8 Elgin 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
1 report 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.

Timing and place names from NOAA ground reports
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Lake Ellsworth — beyond Elgin itself.
Damage-capable hail signal
What 1" hail means for Elgin roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

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.
