Hail in Argonia May 18, 2026
The radar-estimated size surface caught this storm, reaching 2.5" aloft. NEXRAD logged no point detections over Argonia this day. At 2.5" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Argonia saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar-estimated hail size
Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Max size

Only the radar-estimated size surface resolved for May 18, 2026 — this storm produced no NEXRAD point detections over Argonia, so there is one map to show, not two.
Where May 18, 2026 sits in Argonia's hail record
This was Argonia's 3rd recorded hail day, arriving 31 days after the Apr 17, 2026 storm. By severity it ranks 2nd of the 10 storms we have logged here. Radar put the day's largest stone over Argonia at 2.5" — radar-estimated size aloft.
The May 18, 2026 convective day was bigger than Argonia: the same system put hail over 726 other tracked cities, 258 of them in Kansas. Nearest: Harper (6 miles west, up to 2"); Milan (6 miles east, up to 2"); Danville (9 miles northwest, up to 2").
These maps are stills from Argonia's May 18, 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.

What 2.5" hail means for Argonia 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.
What this storm is worth to a roofer

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.
