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.

Summary: 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 fair 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.
