Hail in Gridley · Apr 26, 2026
NEXRAD logged 33 hail signatures up to 3.75"; the estimated-size surface reached 2.25" aloft. At 3.75" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Gridley saw the hail — from two instruments
Apr 26, 2026 · Gridley, 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
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.

The storm in context
Where Apr 26, 2026 sits in Gridley's hail record.
This was Gridley's 3rd recorded hail day, arriving 26 days after the Mar 31, 2026 storm. By severity it ranks 1st of the 10 storms we have logged here. Radar put the day's largest stone over Gridley at 3.75" — the largest NEXRAD radar signature.
The Apr 26, 2026 convective day was bigger than Gridley: the same system put hail over 710 other tracked cities, 277 of them in Kansas. Nearest: Le Roy (5 miles east, up to 2.5"); Yates Center (7 miles south, up to 2.75"); Burlington (7 miles north, up to 1").
These maps are stills. In the app this date is one of 10 Gridley 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.

Severe hail signal
What 3.75" hail means for Gridley roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 Aug 6, 2026.
