Hail in Orland Park Jul 27, 2026

Hit 7 days ago

The radar-estimated size surface caught this storm, reaching 4" aloft. NEXRAD logged no point detections over Orland Park this day. At 4" — softball or larger — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

A tornado was also reported to the National Weather Service during this storm — see the ground reports below.

Two ways to read the storm

How Orland Park 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.

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.

Severe, roof-replacing hail

What 4" hail means for Orland Park roofs

Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.

Other storms in Orland Park

A storm day here is a convective day — it runs from noon to noon UTC, so late-night hail is grouped with the afternoon storm that spawned it rather than split across two calendar dates. Ground reports are public-domain observations from the NOAA Storm Prediction Center. Radar surfaces are detections and estimates, not confirmed damage. Last updated Aug 3, 2026.
