Evidence / storm surfaces

How Clay Center saw the hail — from two instruments

Sep 12, 2026 · Clay Center, KS

Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.

Radar-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Clay Center, KS on Sep 12, 2026 Estimated size field

Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.

Max size 1.75"

Only the radar-estimated size surface resolved for Sep 12, 2026 — this storm produced no NEXRAD point detections over Clay Center, so there is one map to show, not two.

The storm in context

Where Sep 12, 2026 sits in Clay Center's hail record.

This was Clay Center's 20th recorded hail day, arriving 28 days after the Aug 15, 2026 storm. By severity it ranks 3rd of the 20 storms we have logged here. Radar put the day's largest stone over Clay Center at 1.75" — radar-estimated size aloft.

These maps are stills. In the app this date is one of 20 Clay Center 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

No reports filed with the NWS

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 Clay Center 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.

High damage potential

What 1.75" hail means for Clay Center roofs.

Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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 tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 13, 2026.
