Overland Park hail storm history
Johnson County·NOAA NCEI Storm Events Database·~75-day publication lag
Overland Park, located in Johnson County, has experienced 6 hail events of at least 1 inch diameter in the past 10 years, with an average of 0.6 events per year. The city sits in the central Great Plains where the dryline—the boundary between Gulf moisture and drier continental air—creates conditions favorable for hail-producing supercells. Johnson County's broader record includes 18 documented hail events of at least 1 inch, reflecting the region's exposure to severe thunderstorm activity.
Hail in Overland Park peaks during May and June, with secondary activity in April and July. The most damaging events typically occur on late afternoons when atmospheric instability reaches its maximum, and the collision between moist Gulf air and dry continental air generates the strongest updrafts. The largest recorded hail event in Johnson County was 1.75 inches on September 16, 2025, a size capable of functional damage to standard roof shingles.

Overland Park's low count of 6 events in 10 years reflects NOAA's Storm Events Database reporting density, which captures events primarily when damage is reported or officially surveyed. This means smaller hail events may be undercounted. The city's dense roofing contractor market and suburban development likely increase reporting rates compared to rural areas. 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.
