Overview
A strong spring storm system brought multiple rounds of thunderstorms and heavy rain to portions of the Midwest during the weekend of April 29th-30th. Rainfall totals surpassed nine inches in some locations and this led flash flooding and historic flooding along some of the tributaries of the Missouri and Mississippi Rivers. A few thunderstorms also became severe during the afternoon of April 29th, with two weak tornadoes documented.
