Evidence / storm surfaces
How Island Lake saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Only the radar-estimated size surface resolved for Aug 9, 2026 — this storm produced no NEXRAD point detections over Island Lake, so there is one map to show, not two.
The storm in context
Where Aug 9, 2026 sits in Island Lake's hail record.
This was Island Lake's 3rd recorded hail day, arriving 86 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 Island Lake at 0.5" — radar-estimated size aloft.
The Aug 9, 2026 convective day was bigger than Island Lake: the same system put hail over 453 other tracked cities, 69 of them in Illinois. Nearest: Grayslake (5 miles east, up to 0.5"); Mchenry (5 miles west, up to 0.5"); Lake Villa (9 miles northeast, up to 0.5").

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.
No ground reports were filed with the National Weather Service for this storm over Island Lake. 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.
Below the severe threshold
What 0.5" hail means for Island Lake roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$46M
Potential roof exposure — 3,855 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 19 jobs
- Illustrative work
- ~$285K
Close just 0.5% of the 3,855 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
August 2028
Claims from this storm can typically be filed until around August 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 $810 on top of the $150 plan.
