Evidence / storm surfaces
How Lisle saw the hail — from two instruments
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.
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
Only the NEXRAD radar-signature surface resolved for Mar 26, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Mar 26, 2026 sits in Lisle's hail record.
This was Lisle's 2nd recorded hail day, arriving 16 days after the Mar 10, 2026 storm. By severity it ranks 6th of the 7 storms we have logged here. Radar put the day's largest stone over Lisle at 1.25" — the largest NEXRAD radar signature.
The Mar 26, 2026 convective day was bigger than Lisle: the same system put hail over 316 other tracked cities, 103 of them in Illinois. Nearest: Downers Grove (5 miles east, up to 1.25"); Lemont (9 miles southeast, up to 1.75"); Western Springs (10 miles east, up to 1").

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.
No ground reports were filed with the National Weather Service for this storm over Lisle. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Damage-capable hail signal
What 1.25" hail means for Lisle roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$58M
Potential roof exposure — 4,858 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 24 jobs
- Illustrative work
- ~$360K
Close just 0.5% of the 4,858 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
March 2028
Claims from this storm can typically be filed until around March 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 $1,020 on top of the $150 plan.
