Hail in Hebron May 17, 2026
Both radar surfaces caught this storm: NEXRAD logged 85 hail signatures up to 3.25", and the radar-estimated size reached 1.5" aloft. At 3.25" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.
A tornado was also reported to the National Weather Service during this storm — see the ground reports below.

How Hebron 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 May 17, 2026 sits in Hebron's hail record
This was Hebron's 3rd recorded hail day, arriving 1 day after the May 16, 2026 storm. By severity it ranks 1st of the 7 storms we have logged here. Radar put the day's largest stone over Hebron at 3.25" — the largest NEXRAD radar signature.
The May 17, 2026 convective day was bigger than Hebron: the same system put hail over 894 other tracked cities, 185 of them in Nebraska. Nearest: Deshler (9 miles southwest, up to 3"); Bruning (11 miles north, up to 3"); Carleton (13 miles northwest, up to 2.5").
These maps are stills from Hebron's May 17, 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.

How the storm moved
The storm tracked north at roughly 15 mph, based on the timing of ground reports.
Hail was reported over 32 minutes, from to .
Reports came from Deshler and Davenport — beyond Hebron itself.
What 3.25" hail means for Hebron 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.
