Evidence / storm surfaces
How Sullivan saw the hail — from two instruments
May 4, 2026 · Sullivan, 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.
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 May 4, 2026 sits in Sullivan's hail record.
This was Sullivan's 4th recorded hail day, arriving 7 days after the Apr 27, 2026 storm. By severity it ranks 3rd of the 5 storms we have logged here. Radar put the day's largest stone over Sullivan at 1" — the largest NEXRAD radar signature.
The May 4, 2026 convective day was bigger than Sullivan: the same system put hail over 428 other tracked cities, 239 of them in Illinois. Nearest: Bethany (5 miles west, up to 1"); Lovington (7 miles north, up to 1"); Hammond (14 miles north, up to 0").

Damage-capable hail signal
What 1" hail means for Sullivan 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 2, 2026.
