Evidence / storm surfaces
How Lisle saw the hail — from two instruments
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.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
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.
The storm in context
Where Jul 3, 2026 sits in Lisle's hail record.
This was Lisle's 6th recorded hail day, arriving 1 day after the Jul 2, 2026 storm. By severity it ranks 4th of the 7 storms we have logged here. Radar put the day's largest stone over Lisle at 1.5" — the largest NEXRAD radar signature.
The Jul 3, 2026 convective day was bigger than Lisle: the same system put hail over 1,885 other tracked cities, 215 of them in Illinois. Nearest: Wheaton (0 miles north, up to 1.5"); Naperville (6 miles southwest, up to 1"); Carol Stream (7 miles north, up to 1.5").

Ground reports
What people on the ground reported
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.
For this storm over Lisle, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
High damage potential
What 1.5" hail means for Lisle roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$171M
Potential roof exposure — 14,241 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 71 jobs
- Illustrative work
- ~$1.1M
Close just 0.5% of the 14,241 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
July 2028
Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
