How Berwyn 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.
Radar-estimated hail size
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 Mar 10, 2026 — this storm produced no NEXRAD point detections over Berwyn, so there is one map to show, not two.
Where Mar 10, 2026 sits in Berwyn's hail record
This was Berwyn's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 3rd of the 4 storms we have logged here. Radar put the day's largest stone over Berwyn at 1" — radar-estimated size aloft.
The Mar 10, 2026 convective day was bigger than Berwyn: the same system put hail over 470 other tracked cities, 100 of them in Illinois. Nearest: Western Springs (5 miles west, up to 1.25"); Lemont (12 miles southwest, up to 1.25"); Lisle (15 miles west, up to 1").
These maps are stills from Berwyn's Mar 10, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
What people on the ground reported

Reports came from Stickney, Brookfield, Cicero, and North Riverside — beyond Berwyn itself.
What 1" hail means for Berwyn roofs
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.
What this storm is worth to a roofer

Other storms in Berwyn
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.
