Evidence / storm surfaces
How Decatur saw the hail — from two instruments
Jun 17, 2026 · Decatur, IL
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.

Only the radar-estimated size surface resolved for Jun 17, 2026 — this storm produced no NEXRAD point detections over Decatur, so there is one map to show, not two.

Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
The storm tracked northeast at roughly 10 mph, based on the timing of ground reports.
Hail was reported over 75 minutes, from to .
Reports came from Niantic, Elwin, Boody, and Decatur Airport — beyond Decatur itself.
Severe hail signal
What 2.75" hail means for Decatur 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.

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.
