Evidence / storm surfaces
How Kansas City saw the hail — from two instruments
Apr 15, 2026 · Kansas City, MO
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.
Radar-estimated hail size Surface resolved
Estimated size field 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.

Only the radar-estimated size surface resolved for Apr 15, 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 Apr 15, 2026 sits in Kansas City's hail record.
This was Kansas City's 3rd recorded hail day, arriving 36 days after the Mar 10, 2026 storm. By severity it ranks 10th of the 17 storms we have logged here. Radar put the day's largest stone over Kansas City at 0.5" — radar-estimated size aloft.
The Apr 15, 2026 convective day was bigger than Kansas City: the same system put hail over 425 other tracked cities, 59 of them in Missouri. Nearest: Lees Summit (9 miles southeast, up to 0.5"); Pleasant Hill (17 miles southeast, up to 0.75"); Bucyrus (19 miles southwest, up to 0.75").
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.

Below the severe threshold
What 0.5" hail means for Kansas City roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

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.
