Evidence / storm surfaces
How Lake Zurich saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Apr 14, 2026 — this storm produced no NEXRAD point detections over Lake Zurich, so there is one map to show, not two.
The storm in context
Where Apr 14, 2026 sits in Lake Zurich's hail record.
This was Lake Zurich's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 4th of the 5 storms we have logged here. Radar put the day's largest stone over Lake Zurich at 1" — radar-estimated size aloft.
The Apr 14, 2026 convective day was bigger than Lake Zurich: the same system put hail over 476 other tracked cities, 44 of them in Illinois. Nearest: Arlington Heights (7 miles south, up to 1"); Hoffman Estates (7 miles south, up to 1"); Mount Prospect (10 miles southeast, up to 0.75").
These maps are stills. In the app this date is one of 5 Lake Zurich 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
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 Lake Zurich. 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" hail means for Lake Zurich 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
$477M
Potential roof exposure — 39,737 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 199 jobs
- Illustrative work
- ~$3M
Close just 0.5% of the 39,737 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
April 2028
Claims from this storm can typically be filed until around April 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 $8,345 on top of the $150 plan.
