Hail in Fredonia · Apr 26, 2026
NEXRAD logged 45 hail signatures up to 4"; the estimated-size surface reached 2.25" aloft. At 4" — softball or larger — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.
A tornado was also reported to the National Weather Service during this storm. The ground reports below show where it was filed.

Evidence / storm surfaces
How Fredonia saw the hail — from two instruments
Apr 26, 2026 · Fredonia, 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.
NEXRAD radar signatures Surface resolved
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.

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 Fredonia's hail record.
This was Fredonia's 8th recorded hail day, arriving 3 days after the Apr 23, 2026 storm. By severity it ranks 1st of the 16 storms we have logged here. Radar put the day's largest stone over Fredonia at 4" — the largest NEXRAD radar signature.
The Apr 26, 2026 convective day was bigger than Fredonia: the same system put hail over 710 other tracked cities, 277 of them in Kansas. Nearest: Neodesha (9 miles southeast, up to 4"); Altoona (13 miles northeast, up to 2.5"); Elk City (15 miles south, up to 2.75").
These maps are stills. In the app this date is one of 16 Fredonia 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.

Reports came from Sycamore — beyond Fredonia itself.
Severe hail signal
What 4" hail means for Fredonia 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 Sep 13, 2026.
