Lee's Summit hail storm history
Jackson County·NOAA NCEI Storm Events Database·~75-day publication lag
Lee's Summit, located in Jackson County, has experienced 3 hail events of 1 inch or larger over the past 10 years according to NOAA Storm Events data. The city sits on the western edge of the Midwest, positioning it where Great Plains dryline storms and frontal systems regularly move eastward from Kansas into Missouri during spring months.
Hail in the Lee's Summit area peaks during April, May, and June, with secondary activity occurring in March and July. Storms that produce hail in this region typically originate along the Kansas dryline before tracking into Missouri, bringing the potential for quarter-inch to larger hailstones across Jackson County.

Jackson County's documented hail record is limited in size and frequency, which reflects both the actual storm climatology of the region and the density of trained spotters and damage-reporting networks. The largest recorded hail event in the county measured 1 inch on September 18, 2025—a marginal damage threshold where granule loss on aging roof shingles becomes probable. 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.
