Kansas City hail storm history
Jackson County·NOAA NCEI Storm Events Database·~75-day publication lag
Jackson County, which includes Kansas City, has experienced 2 documented hail events of 1 inch or larger over the past 10 years, according to NOAA Storm Events data. Kansas City sits on the western edge of the Midwest where Great Plains dryline storms and frontal systems regularly produce large hail as they track from Kansas into Missouri.
Hail in Kansas City follows a strong seasonal pattern, with peak activity occurring from April through June. March and July represent secondary risk months. Kansas City-area storms often originate on the Kansas dryline before tracking into Missouri, meaning residents may see storm warnings develop first in western counties before reaching the Kansas City metro area.

Jackson County's low event count reflects both actual hail frequency and NOAA reporting density in urban areas, where smaller hail events may not be systematically documented. The largest recorded hail event in the county was 1 inch on September 17, 2025—a marginal damage threshold that typically causes granule loss on aging shingles but does not trigger widespread functional roof damage. Current-year data is excluded from the annual frequency table until October, when NOAA's Storm Events Database has processed the full hail season accounting for the standard 75-day reporting lag.
