...F1 Tornado Strikes St. James, Missouri...

An unusually powerful storm system affected much of the central U.S. bringing an out of season and rare September outbreak of severe thunderstorms and tornadoes to portions of Missiouri, Illinois, Arkansas and Kentucky. Supercell thunderstorms developed early Friday afternoon over portions of the Missouri and northern Arkansas, moving quickly eastward across the mid Mississippi valley leaving paths of damage, and in some cases destruction, in their wake as they spawned numerous tornadoes. In the National Weather Service Springfield area of responsibility one tornado touched down producing F1 intensity damage in the town of St. James in northeastern Phelps County. Many additional tornadoes touched down in the St. Louis, Little Rock, and Paducah National Weather Service offices' areas of responsibility.
