Yes, leeneia, there is a Tornado Alley.

See Wikipedia for description of "Tornado Alley," applied to the area between the Rocky Mountains and the Appalachian Mountains.

The term "Tornado Alley" was first used in 1952 by U. S. Air Force meteorologists Major Ernest J. Fawbush and Captain Robert C. Miller as the title of a research project to study severe weather in parts of Texas and Oklahoma.

There also is a "Dixie Alley" and several smaller alleys.

See John P. Gagan et al., A historical and statistical comparison of "Tornado Alley" to "Dixie Alley", National Weather Digest, Dec. 2010, vol. 34, no. 2, pp. 146-155.
