Tornado Alley

A diagram of tornado alley based on 1 tornado or more per decade. Rough location (red), and its contributing weather systems

Tornado Alley is a loosely defined location of the central United States and Canada where tornadoes are most frequent.[1] The term was first used in 1952 as the title of a research project to study severe weather in areas of Texas, Louisiana, Oklahoma, Kansas, South Dakota, Iowa and Nebraska. Tornado climatologists distinguish peaks in activity in certain areas[2] and storm chasers have long recognized the Great Plains tornado belt.[3]

As a colloquial term there are no definitively set boundaries of Tornado Alley, but the area common to most definitions extends from Texas, through Oklahoma, Kansas, Nebraska, South Dakota, Iowa, Minnesota, Wisconsin, Illinois, Indiana, Missouri, Arkansas, North Dakota, Montana, Ohio, and eastern portions of Colorado and Wyoming.[4] Research suggests that the main alley may be shifting eastward away from the Great Plains,[5][6] and that tornadoes are also becoming more frequent in the northern and eastern parts of Tornado Alley where it reaches the Canadian Prairies, Ohio, Michigan, and Southern Ontario.[7][8]
