Tornadoes are more common in April, May, and June than in February or March. The two most fundamental ingredients needed for making tornadoes are instability and wind shear. Instability occurs when the lower atmosphere is warm and moist and cools quickly with increasing height. Instability allows thunderstorms to form. Wind shear occurs when the speed and direction of wind changes with altitude.
Wind shear tends to be strongest in winter and weakest in summer, while the opposite is true of instability. The most ideal combination of wind shear and instability generally occurs in the spring.
Tornadoes are most frequent in the central plains of the United States, often referred to as "Tornado Alley." This region includes parts of Texas, Oklahoma, Kansas, and Nebraska. Tornadoes can occur throughout the year, but peak season typically falls between April and June.
