Evidence / storm surfaces
How Kansas City saw the hail — from two instruments
Aug 18, 2026 · Kansas City, MO
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.

The storm in context
Where Aug 18, 2026 sits in Kansas City's hail record.
This was Kansas City's 16th recorded hail day, arriving 9 days after the Aug 9, 2026 storm. By severity it ranks 1st of the 17 storms we have logged here. Radar put the day's largest stone over Kansas City at 2" — radar-estimated size aloft.
The Aug 18, 2026 convective day was bigger than Kansas City: the same system put hail over 309 other tracked cities, 39 of them in Missouri. Nearest: Independence (13 miles northeast, up to 1.5"); Kansas City (19 miles northwest, up to 1.75"); Liberty (19 miles northeast, up to 0.5").

Severe hail signal
What 2" hail means for Kansas City 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 7, 2026.
