How Kansas City saw the hail — from two instruments

Oct 13, 2026 · Kansas City, MO

The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.

Radar-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Kansas City, MO on Oct 13, 2026 Estimated size field

The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.

Max size 0.75"

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

The storm in context

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

This was Kansas City's 18th recorded hail day, arriving 37 days after the Sep 6, 2026 storm. By severity it ranks 8th of the 18 storms we have logged here. Radar put the day's largest stone over Kansas City at 0.75" — radar-estimated size aloft.

The Oct 13, 2026 convective day was bigger than Kansas City: the same system put hail over 183 other tracked cities, 36 of them in Missouri. Nearest: Liberty (11 miles east, up to 0.75"); Independence (16 miles east, up to 0.75"); Lawson (25 miles northeast, up to 0.5").

These maps are stills. In the app this date is one of 18 Kansas City 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 Waldron — beyond Kansas City itself.

Near the severe threshold

What 0.75" hail means for Kansas City roofs.

A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

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.
