Detailed explanation-1: -The Great Plains are conducive to the type of thunderstorms (supercells) that spawn tornadoes. It is in this region that cool, dry air in the upper levels of the atmosphere caps warm, humid surface air.

Detailed explanation-2: -The Midwestern states are very prone to tornado activity, as they are part of “Tornado Alley.” States included in the area that are hit by tornadoes the most are Oklahoma, Kansas, Missouri, Nebraska, Iowa, and South Dakota.

Detailed explanation-3: -Tornado alley is a cluster of states in the midwestern US where tornadoes are most likely to occur. Tornado alley is typically identified as including parts of Texas, Oklahoma, Kansas, Nebraska, South Dakota, Indiana, Missouri, Iowa, Illinois, and Ohio.

Detailed explanation-4: -In Tornado Alley, warm, humid air from the equator meets cool to cold, dry air from Canada and the Rocky Mountains. This creates an ideal environment for tornadoes to form within developed thunderstorms and supercells.

Detailed explanation-5: -The region of maximum tornado frequency known as Tornado Alley extends from west Texas northeast through the western and central portions of Oklahoma and Kansas and across most of Nebraska.
