Kansas City is located in "[[Tornado Alley]]", a broad region where cold air from Canada collides with warm air from the Gulf of Mexico, leading to the formation of powerful storms, especially during the spring. The Kansas City metropolitan area has experienced several significant outbreaks of [[tornado]]es in the past, including the [[May 1957 Central Plains tornado outbreak|Ruskin Heights tornado in 1957]]<ref>{{cite web|url=http://www.wdaftv4.com/almanac/watorndo.html |title=Kansas City Tornado Almanac |archive-url=https://web.archive.org/web/20020824021557/http://www.wdaftv4.com/almanac/watorndo.html |archive-date=August 24, 2002 }}</ref> and the [[May 2003 tornado outbreak sequence]].
