Episode Narrative: A strong spring storm system brought multiple rounds of thunderstorms and heavy rain to the southeast half of Missouri during the weekend of April 29th-30th. Rainfall totals surpassed nine inches in some locations and this led to flash flooding and 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. A few thunderstorms also became severe during the afternoon of April 29th, with two weak tornadoes documented. A strong spring storm system brought multiple rounds of thunderstorms and heavy rain to the southeast half of Missouri during the weekend of April 29th-30th. Event Narrative:  Thunderstorm winds blew down a one foot diameter tree. The Meramec and Big Rivers rose above major flood stage in the late evening hours of April 30th due to the heavy rainfall. A number of roads were closed due to the river flooding. A 77-year old man drowned when he walked to a creek (that feeds into the nearby Big River) near his house (off of Mimi Mountain Road and Highway BB) to survey the rising water, slipped and was swept away by the current. His body was recovered about three quarters of a mile downstream. The Cuivre River crested just above major stage at Troy, while it rose to about 2 feet over major stage at Old Monroe due to the heavy rainfall. Numerous roads were flooded due to the river flooding. A weak tornado touched down to the southwest of the intersection of Missouri Highway B and Huster Road causing minor damage to trees in this area and traveled northeast to the small community of South Shore where several single family homes experienced minor damage, while outbuildings or sheds were destroyed. Damage to structures and trees were consistent with wind speeds of 80 mph. The tornado moved northeast and intersected a line of parked campers and boats along Dwyer Club Road. At least half of a dozen boats and campers were tossed to the northeast and destroyed by the tornado. Several trees in this area were uprooted, mainly due to the very wet soil. The damage path was 100 yards wide at this location. The tornado then hit an outbuilding on Dwyer Road, lifting most of the roof panels to the northeast. The tornado passed just to the east of Yacht Club Harbor with only a few tree limbs broken in this area. The Lake Center Marina did not fare so well, with two boat docks lifted and twisted into the trees on the south end of the property. The tornado lifted shortly thereafter with no visible damage to the north of this location. Overall, the tornado was rated EF0 with max wind speeds of 80 MPH. Path length is 3.85 miles with a max path width of 100 yards. The Meramec River at Eureka and Valley Park rose to just above major flood stage in the late evening hours of April 30th due to the heavy rainfall. A number of roads were closed due to the river flooding including Highway 141 where it goes under I-44.
