Several tornadoes occurred in Lee's Summit and just west-southwest of the Pleasant Hill Weather Forecast Office. The most significant of the three confirmed tornadoes occurred in Lee's Summit. This tornado did only minor structural damage The storms also produced widespread heavy rainfall and there were numerous reports of 3 to 5+ rainfall reports.
