The estimated-size surface reached 0.75" aloft; NEXRAD logged no point detections over Lisle that day. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
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.
Estimated size field 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.
The storm in context
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: Downers Grove (5 miles east, up to 0.75"); Naperville (6 miles southwest, up to 0.75"); Carol Stream (7 miles north, up to 0.75").
These maps are stills. In the app this date is one of 7 Lisle storm dates on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.
Ground reports
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
Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Bolingbrook and Woodridge — beyond Lisle itself.
Near the severe threshold
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

Roofing exposure
Potential roof exposure
$258M
Potential roof exposure — 21,511 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 21,511 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
June 2028
Claims from this storm can typically be filed until around June 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $4,517 on top of the $150 plan.
