| Brief Description: EVENT NARRATIVE: An EF2 tornado touched down at 17:09 CST, 2 miles north-northwest of Kirksville. This tornado traveled east over northern portions of Kirksville, before lifting at 17:20 CST, 2 miles west-southwest of the town of Clay. This tornado killed two people and damaged numerous homes in northern Kirksville. Ten homes were destroyed and fifteen others suffered major damage. Up to 186 other buildings and homes had minor to moderate damage. Two dealerships suffered major damage. Several farmsteads suffered damage east of Kirksville. EPISODE NARRATIVE: During the evening of May 13, 2009, a series of powerful supercell storms developed ahead of a cold front, pushing southward out of Iowa and Nebraska. These supercell storms produced a wide array of severe weather, with large hail up to the size of golf balls and winds up to 60 mph reported. These storms marched across eastern Kansas and northern Missouri during the evening hours, with a strong supercell storm producing tornadic activity in parts of northeast Missouri. Damage surveys conducted by the National Weather Service, in conjunction with emergency management, have found evidence of three tornadoes in Sullivan and Adair counties. All tornadoes appeared to have been produced by the same supercell thunderstorm. There were three fatalities. Moderate to severe damage was reported, in the Kirksville area. | |||||||||||

| Brief Description: After dissipating just west of Atlanta, a new tornado touched down 1 mile southeast of Atlanta and moved northeast into Knox County. In Macon County, 5 single family residences and 3 mobile homes were destroyed from 2 miles east of Atlanta to 10 miles northeast of Atlanta. Four single family homes were damaged within this area. Several outbuildings were also damaged or destroyed. Some damage south of the tornado track was likely due to the very intense rear flank downdraft, which storm spotters observed to accompany the storm.

The outbreak included at least five tornadoes, one of which moved along a 54-mile path across three counties.
