Hail in Attica · Oct 13, 2026

Hit 9 days ago

The estimated-size surface reached 2.25" aloft; NEXRAD logged no point detections over Attica that day. At 2.25" — tennis ball — 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 Attica saw the hail — from two instruments

Oct 13, 2026 · Attica, KS

We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.

Radar-estimated hail size Surface resolved
Map image is still rendering for this surface.

Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

Max size 2.25"

Only the radar-estimated size surface resolved for Oct 13, 2026 — this storm produced no NEXRAD point detections over Attica, so there is one map to show, not two.

The storm in context

Where Oct 13, 2026 sits in Attica's hail record.

This was Attica's 12th recorded hail day, arriving 28 days after the Sep 15, 2026 storm. By severity it ranks 1st of the 12 storms we have logged here. Radar put the day's largest stone over Attica at 2.25" — radar-estimated size aloft.

The Oct 13, 2026 convective day was bigger than Attica: the same system put hail over 183 other tracked cities, 57 of them in Kansas. Nearest: Hazelton (11 miles southwest, up to 2.25"); Sharon (12 miles west, up to 1.75"); Harper (13 miles northeast, up to 1.5").

These maps are stills. In the app this date is one of 12 Attica 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 2.25" hail means for Attica 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 Oct 14, 2026.
