Evidence / storm surfaces
How Bunker Hill 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 May 31, 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 May 31, 2026 sits in Bunker Hill's hail record.
This was Bunker Hill's 3rd recorded hail day, arriving 28 days after the May 3, 2026 storm. By severity it ranks 3rd of the 4 storms we have logged here. Radar put the day's largest stone over Bunker Hill at 0" — radar-estimated size aloft.
The May 31, 2026 convective day was bigger than Bunker Hill: the same system put hail over 637 other tracked cities, 60 of them in Illinois. Nearest: Edwardsville (14 miles south, up to 1"); Hartford (16 miles southwest, up to 1"); Marine (16 miles southeast, up to 1").
These maps are stills. In the app this date is one of 4 Bunker Hill 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 Bunker Hill 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.
Below the severe threshold
What 0" hail means for Bunker Hill roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.
