The radar-estimated size surface caught this storm, reaching 2" aloft. NEXRAD logged no point detections over Hazel Crest this day. At 2" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.
A tornado was also reported to the National Weather Service during this storm — see the ground reports below.

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.
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 Jul 27, 2026 — this storm produced no NEXRAD point detections over Hazel Crest, so there is one map to show, not two.
This was Hazel Crest's 2nd recorded hail day, arriving 24 days after the Jul 3, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Hazel Crest at 2" — radar-estimated size aloft.
The Jul 27, 2026 convective day was bigger than Hazel Crest: the same system put hail over 803 other tracked cities, 130 of them in Illinois. Nearest: Markham (0 miles north, up to 2"); Tinley Park (5 miles west, up to 3"); South Holland (5 miles east, up to 1.25").
These maps are stills from Hazel Crest's Jul 27, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.

Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.
