Two ways to read the storm

How Des Plaines 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.

Radar-estimated hail size

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.

Max size 1.25"

Only the radar-estimated size surface resolved for Jul 27, 2026 — this storm produced no NEXRAD point detections over Des Plaines, so there is one map to show, not two.

The storm in context

Where Jul 27, 2026 sits in Des Plaines's hail record

This was Des Plaines's 3rd recorded hail day, arriving 25 days after the Jul 2, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Des Plaines at 1.25" — radar-estimated size aloft.

The Jul 27, 2026 convective day was bigger than Des Plaines: the same system put hail over 803 other tracked cities, 130 of them in Illinois. Nearest: Elk Grove Village (5 miles west, up to 1.75"); Berkeley (7 miles south, up to 1.75"); Melrose Park (7 miles south, up to 1.75").

These maps are stills from Des Plaines's Jul 27, 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.

Shingle-bruising hail

What 1.25" hail means for Des Plaines 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.

Other storms in Des Plaines

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.
