The estimated-size surface reached 4" aloft; NEXRAD logged no point detections over Orland Park that day. At 4" — softball or larger — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.
A tornado was also reported to the National Weather Service during this storm. The ground reports below show where it was filed.

Evidence / storm surfaces
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 Jul 27, 2026 — this storm produced no NEXRAD point detections over Orland Park, so there is one map to show, not two.
The storm in context
This was Orland Park's 4th recorded hail day, arriving 47 days after the Jun 10, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Orland Park at 4" — radar-estimated size aloft.
The Jul 27, 2026 convective day was bigger than Orland Park: the same system put hail over 803 other tracked cities, 130 of them in Illinois. Nearest: Homer Glen (5 miles west, up to 4"); Tinley Park (5 miles east, up to 3"); Willow Springs (7 miles north, up to 4").
These maps are stills. In the app this date is one of 5 Orland Park 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.

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Hail was reported over 15 minutes, from to .
Reports came from Mokena and Homer Glen — beyond Orland Park itself.
Severe hail signal
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

Roofing exposure
Potential roof exposure
$449M
Potential roof exposure — 37,380 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 37,380 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.
Names and phones for every home in the footprint: at most $7,850 on top of the $150 plan.
