Evidence / storm surfaces
How Byron 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.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
Only the NEXRAD radar-signature surface resolved for Mar 30, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Mar 30, 2026 sits in Byron's hail record.
This was Byron's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 6th of the 8 storms we have logged here. Radar put the day's largest stone over Byron at 1" — the largest NEXRAD radar signature.
The Mar 30, 2026 convective day was bigger than Byron: the same system put hail over 313 other tracked cities, 70 of them in Illinois. Nearest: Winnebago (7 miles north, up to 1"); Stillman Valley (9 miles southeast, up to 1"); Davis Junction (12 miles southeast, up to 1").
These maps are stills. In the app this date is one of 8 Byron 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.
Ground reports
What people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.
Nobody on the ground filed a report over Byron for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Damage-capable hail signal
What 1" hail means for Byron roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.
