Evidence / storm surfaces
How Berwyn saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Only the radar-estimated size surface resolved for Jul 27, 2026 — this storm produced no NEXRAD point detections over Berwyn, so there is one map to show, not two.
The storm in context
Where Jul 27, 2026 sits in Berwyn's hail record.
This was Berwyn's 4th recorded hail day, arriving 33 days after the Jun 24, 2026 storm. By severity it ranks 2nd of the 5 storms we have logged here. Radar put the day's largest stone over Berwyn at 1.5" — radar-estimated size aloft.
The Jul 27, 2026 convective day was bigger than Berwyn: the same system put hail over 803 other tracked cities, 130 of them in Illinois. Nearest: Western Springs (5 miles west, up to 2.25"); Bridgeview (7 miles south, up to 2.75"); Palos Hills (7 miles south, up to 2.75").

Storm forensics
How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
The storm tracked southeast at roughly 5 mph, based on the timing of ground reports.
Hail was reported over 69 minutes, from to .
Reports came from La Grange Park and Midway Airport — beyond Berwyn itself.
High damage potential
What 1.5" hail means for Berwyn roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$2.1B
Potential roof exposure — 175,643 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
