Kansas City hail history

Kansas City hail history: what’s happened, and when.

Hail-report days by year and month, the biggest storms, and how to see what was recorded at or near your own address.

The short answer

Since 2016, the National Weather Service logged hail 1 inch or larger within 30 miles of downtown Kansas City on 94 separate days, about 8.1 a year (2016–2025). April and May have had the most hail-report days. The largest reported stone was 4.5 in (grapefruit) on March 10, 2026, near Weatherby Lake (a preliminary report). Data through November 10, 2026.

Kansas City hail by the numbers

How we count. A hail-report day is a storm day (NOAA’s noon-to-noon UTC day) with at least one National Weather Service hail report of 1 inch or larger within 30 miles of downtown Kansas City, Missouri; several reports on the same day count once.

These numbers update as NOAA publishes new reports; they run through November 10, 2026.

The full method and source

We count Kansas City hail from the public NOAA records behind every Roof Inspectors storm report: National Weather Service storm reports since 2016, plus NOAA radar hail estimates since October 14, 2020. The area is everything within 30 miles of downtown Kansas City, Missouri.

“Largest hail” is the biggest report of any size. Reports come from trained spotters, emergency managers, the public and weather stations, so they show where people saw hail, not every place it fell.

Radar hail days use NOAA’s MRMS estimate of the largest hail over the same area, counted only when the Weather Service also logged hail within 15 miles that day, with implausible readings over about 6 inches dropped. Radar can miss or overstate what reached the ground.

2026 numbers come from preliminary reports and can change when NOAA finalizes them.

Our storm records come from NOAA radar estimates and National Weather Service reports. Radar can miss or misjudge hail, and a report marks a single spot, so records can be incomplete. Treat them as a starting point, not a verdict about your roof.

Hail-report days (1 in+): 94; Since 2016
In a typical year: 8.1; Average, 2016–2025
Largest reported hail: 4.5 in; Grapefruit, Mar 10, 2026
Radar hail days (1 in+): 48; Since 2021

These are records for the wider area, not for your address. A storm on record doesn’t mean your roof was damaged, and it doesn’t mean your insurance company will accept that storm or date. That’s why an inspection is worth having: a roofing professional looks at the roof itself.

Notable Kansas City storms

March 10, 2026: where the largest hail fell

Hail (larger dot, larger hail)Wind gust or damagePreliminary NWS storm reports, March 10, 2026. Hail dots are sized by diameter; hail size varies block to block.

Why neighbors can have different storm histories

Hail falls in swaths that can be a few blocks to a few miles wide — with gaps.
Hail size can change quickly as a storm strengthens or weakens.
Wind drives hail at angles, so one side of a roof (or street) can take more impacts.
Roof age and material change how the same hail affects two homes.

That’s why a metro count can’t tell you about your roof. Storm history by address shows how many storms are on record at or near your home, and what hail damage looks like explains what to look for afterward.
