Independent storm reports filed with the NWS.
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 Waukegan, so there is one map to show, not two.
This was Waukegan's 3rd recorded hail day, arriving 73 days after the May 15, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Waukegan at 1.5" — radar-estimated size aloft.
The Jul 27, 2026 convective day was bigger than Waukegan: the same system put hail over 803 other tracked cities, 130 of them in Illinois. Nearest: Beach Park (5 miles east, up to 1.5"); Lake Villa (5 miles west, up to 0.75"); Lindenhurst (5 miles west, up to 0.75").
These maps are stills from Waukegan'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.
“The KUGN ASOS measured a peak wind gust of 82 mph at 3:43pm out of the northeast. Extensive damage was noted around Waukegan including snapped and uprooted trees. (LOT)”
— NOAA / SPC storm report
Reports came from Beach Park — beyond Waukegan itself.
At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.
