Evidence / storm surfaces
How Aurora saw the hail — from two instruments
Mar 30, 2026 · Aurora, IL
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
NEXRAD radar signatures Surface resolved
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

Radar-estimated hail size Surface resolved
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

The storm in context
Where Mar 30, 2026 sits in Aurora's hail record.
This was Aurora's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over Aurora at 1.75" — the largest NEXRAD radar signature.
The Mar 30, 2026 convective day was bigger than Aurora: the same system put hail over 313 other tracked cities, 70 of them in Illinois. Nearest: Naperville (6 miles southeast, up to 1.75"); Oswego (7 miles south, up to 1.75"); Saint Charles (7 miles north, up to 1").
These maps are stills. In the app this date is one of 6 Aurora 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.

High damage potential
What 1.75" hail means for Aurora 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.

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 tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 10, 2026.
