Evidence / storm surfaces
How Kansas City saw the hail — from two instruments
Apr 17, 2026 · Kansas City, MO
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.
NEXRAD radar signatures Surface resolved
Radar signature field 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.

Radar-estimated hail size Surface resolved
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

The storm in context
Where Apr 17, 2026 sits in Kansas City's hail record.
This was Kansas City's 4th recorded hail day, arriving 2 days after the Apr 15, 2026 storm. By severity it ranks 3rd of the 17 storms we have logged here. Radar put the day's largest stone over Kansas City at 1.75" — the largest NEXRAD radar signature.
The Apr 17, 2026 convective day was bigger than Kansas City: the same system put hail over 1,016 other tracked cities, 169 of them in Missouri. Nearest: Overland Park (9 miles southwest, up to 1"); Independence (13 miles northeast, up to 1.25"); Olathe (14 miles west, up to 1.75").
These maps are stills. In the app this date is one of 17 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.

High damage potential
What 1.75" hail means for Kansas City roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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.
