Wider weather episode

A strong spring storm system brought multiple rounds of thunderstorms and heavy rain to the southeast half of Missouri during the last couple days of April. Rainfall totals surpassed nine inches in some locations and this led to historic flooding along some of the tributaries of the Missouri and Mississippi Rivers. Areas along the Meramec River were especially hard hit as new records were set at Steelville, Sullivan, and Eureka. The previous records had just recently been set during the late December flooding of 2015. Two major highways, I-44 and I-55 were shut down for a number of days due to the record river flooding from this event.
