How Colwich saw the hail — from two instruments

May 18, 2026 · Colwich, 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-signature map of the hail storm over Colwich, KS on May 18, 2026 — 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 map of the storm over Colwich, KS on May 18, 2026 — 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.

Damage-capable hail signal

What 1" hail means for Colwich roofs.

Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure

What this storm is worth to a roofer.

8,902 homes × $12,000 avg. claim

Potential roof exposure

$107M

Potential roof exposure — 8,902 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Illustrative jobs: 45 jobs

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 2, 2026.
