Hail in Aurora Jun 1, 2026
Both radar surfaces caught this storm: NEXRAD logged 21 hail signatures up to 2.25", and the radar-estimated size reached 1.5" aloft. At 2.25" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Aurora 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.
NEXRAD radar signatures
Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

Where Jun 1, 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 3 storms we have logged here. Radar put the day's largest stone over Aurora at 2.25" — the largest NEXRAD radar signature.
The Jun 1, 2026 convective day was bigger than Aurora: the same system put hail over 827 other tracked cities, 43 of them in Colorado. Nearest: Watkins (5 miles east, up to 3.25"); Parker (7 miles south, up to 1.25"); Englewood (11 miles west, up to 1").
These maps are stills from Aurora's Jun 1, 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
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.

Reports came from Buckley Afb — beyond Aurora itself.
What 2.25" hail means for Aurora roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.

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.
