Depending on who is asking, the answer to where is tornado alley varies greatly.
Who is asking? Why are they asking? Where are they asking from?
Much of the United States lives under a near constant yearly threat from tornadoes spawned from supercells.
The answer to where is tornado alley is actually quite complex.
Air Masses Collide
Traditionally, tornado alley is located across the middle of the country in the region known as the Great Plains.
The Great Plains are where most people think when they think of tornado alley â€” and for good reason.
Each Spring, air masses collide to form towering thunderstorms on the Great Plains. These thunderstorms produce hail, damaging winds, and tornadoes.
Tornadoes form when these varying air masses combine over the Great Plains. Hot and dry air moves over the Great Plains from the southwest. That air meets warm and moist air, carried northwards from the Gulf of Mexico. Overhead, cold air carried by the jet stream creates an atmosphere that is highly unstable. Where these masses of air meet is what is known as the dryline. Because of this, the dryline is located most predominantly each Spring on the Great Plains.
The dryline is responsible for the most violent and photogenic storms and tornadoes on Earth. Drylines are a favorite of storm chasers.
Traditional Tornado Alley
In reality, there is some truth to the old definition. The traditional alley lays across the middle of the country, from Canada to Mexico.
Tornadoes form most frequently in the spring months, from April to June. Typically, tornado seasonâ€™s climax occurs in mid to late May each year.
However, tornado seasonâ€™s do not always follow the same path. Some seasons explode violently with over 1000 tornadoes. Other seasons quietly sputter, with only a few hundred tornadoes over open lands.
Consequently, tornado alleyâ€™s location changes from year to year.
More importantly, tornado alley is not just the region known as the Great Plains.
Coining the Phrase
The term tornado alley was used first in 1952 by US Air Force meteorologists Major Ernest J. Fawbush and Captain Robert C. Miller. They used the term as part of a study of extreme weather events from Texas to Nebraska.
From there, tornado alley was also used in a headline in a New York Times article published May 26, 1957. The region known as tornado alley was defined as Texas, Oklahoma, Arkansas, Missouri, and Iowa in that article.
Expanding the Definition
We should expand the definition of tornado alley.
Tornado Alley is not located just on the Great Plains. Tornadoes frequently form across a larger portion of the country. This land area covers much of the United States.
Tornado Alley actually lays across a broad portion of the middle and eastern part of the country. In fact, tornado alley is located between the Rocky Mountains to the west, and the Appalachian mountains to the east.
In this region, tornadoes form at a pace unlike just about anywhere else on earth.
And i believe that the states with the most of the country are Oklahoma,Mississippi and Alabama especially when you consider how strong the tornadoes they get are as well
Question?Where's Dixie Alley And Carolina AlleyActually Located At?And The Reason Why I've asked This Question Is Bcuz?Back In Tornado Season 2017?

Is tornado alley shifting?
Considering how hot the planets gotten and how opposing weather fronts temperatures can vary even more, I really think tornado alley should be revised and widened. It a new century and we should have new maps.
Iâ€™ve lived in Oklahoma my entire life and it almost seems like Tornado Alley is moving more southeast of here. We still get our fare share but it seems like Louisiana, Mississippi, and Alabama are getting more and more.
What about this question why canâ€™t we just make the eastern half of the us tornado alley as noticed one thing itâ€™s the humidity?
