Evidence / storm surfaces

How Summerfield saw the hail — from two instruments

May 18, 2026 · Summerfield, KS

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.

The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.

The storm in context

Where May 18, 2026 sits in Summerfield's hail record.

This was Summerfield's 7th recorded hail day, arriving 1 day after the May 17, 2026 storm. By severity it ranks 1st of the 11 storms we have logged here. Radar put the day's largest stone over Summerfield at 3" — the largest NEXRAD radar signature.

The May 18, 2026 convective day was bigger than Summerfield: the same system put hail over 726 other tracked cities, 258 of them in Kansas. Nearest: Pawnee City (9 miles northeast, up to 2.75"); Burchard (9 miles northwest, up to 2.5"); Beattie (9 miles southwest, up to 3").

These maps are stills. In the app this date is one of 11 Summerfield 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" hail means for Summerfield 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 3, 2026.
