| Brief Description: EVENT NARRATIVE: A tornado touched down about a mile and a quarter south southeast of Kimmswick on the Illinois side of the Mississippi River. It travelled to the northeast for about 7 miles before lifting and dissipating. Several large trees were blown down just west the levee in a two and a half mile area along the path. The greatest degree of damage occurred on County Road 200E just south of the intersection with Merrimac Road. The roof of a two story home was approximately 80 percent removed. A second roof to a porch was totally removed and blown to the north northeast. Window and siding damage was also observed. Several trees and large limbs at the back of this home were severely damaged and helped to show a large convergent damage pattern. Two other homes west of the first home sustained varying degrees of damage. Roof, window and siding damage was common on these two homes. A large hanger at Jacobs Field, northeast of the home damage, sustained varying degrees of damage. Large sections of the hanger's metal roof were blown a quarter to half a mile to the north northeast. The tornado continued to damage small to medium sized machine sheds and caused minor damage to a few homes along the rest of its path. No injuries were reported.

| Brief Description: EVENT NARRATIVE: A National Weather Service storm survey revealed that an EF-3 tornado tracked into northeast Phelps County. The tornado impacted areas on the northern edge of Jerome destroying one home and several oubuildings. EPISODE NARRATIVE: An unusual mid winter tornado outbreak occurred over southwest and central Missouri. 31 tornadoes struck the region within a 15 hour time frame on 7 January into early morning 8 January. Two tornadoes intensified to EF-3 status while five tornadoes caused EF-2 damage. All other tornadoes during this outbreak were surveyed and given EF-0 and EF-1 status. Multiple training supercells spawned most of these tornadoes that occurred along the Interstate 44 corridor. Toward the end of this episode, a broken squall line spawned numerous EF-0 and EF-1 tornadoes across the southern Missouri Ozarks. | |||||||||||
