Largest hailstone — the top predictor of roof damage.
How many homes sit inside the storm's footprint.
Independent storm reports filed with the NWS.
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Only the radar-estimated size surface resolved for Jun 10, 2026 — this storm produced no NEXRAD point detections over Lisle, so there is one map to show, not two.
This was Lisle's 4th recorded hail day, arriving 72 days after the Mar 30, 2026 storm. By severity it ranks 5th of the 7 storms we have logged here. Radar put the day's largest stone over Lisle at 0.75" — radar-estimated size aloft.
The Jun 10, 2026 convective day was bigger than Lisle: the same system put hail over 777 other tracked cities, 81 of them in Illinois. Nearest: Naperville (5 miles west, up to 0.75"); Downers Grove (5 miles east, up to 0.75"); Carol Stream (7 miles north, up to 0.75").
These maps are stills from Lisle's Jun 10, 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.
“Numerous tree limbs of varying sizes downed in the general area. A one foot diameter tree branch downed on Lisson Road blocking southbound traffic. Estimated 60 to 65 m (LOT)”
— NOAA / SPC storm report
“60 to 65 mph estimated wind gusts. Time estimated by radar. (LOT)”
— NOAA / SPC storm report
Reports came from Bolingbrook and Woodridge — beyond Lisle itself.
Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.
