  Tornadoes....Nature's Most Violent Storms
A tornado is defined as a violently rotating column of air extending from a thunderstorm to the ground.
Tornadoes in the winter and early spring are often associated with strong, frontal systems that form in the Central States and move east.
Remember, tornadoes occasionally develop in areas in which a severe thunderstorm watch or warning is in effect.

  Tornado - Wikipedia, the free encyclopedia
A tornado is a violently rotating column of air which is in contact with both a cumulonimbus (or, in rare cases, cumulus) cloud base and the surface of the earth.
The longest modern-day damage path was caused by a tornado which was on the ground for 160 miles (260 km) in northeastern North Carolina on November 22, 1992.
Tornadoes occurring in these conditions are especially dangerous, since only radar observations, or possibly the sound of an approaching tornado, serve as any warning to those in the storm's path.

Tornadoes and the threat of tornadoes are a key part of the USA's spring weather because spring brings favorable tornado conditions.
The strongest tornadoes are often near the edge of the updraft, not far from where air is descending in a downdraft caused by the thunderstorms with falling rain or hail.
Tornadoes are commonly associated with the nation's heartland – in a 10-state area stretching from Texas to Nebraska that also includes Colorado, Iowa, Illinois, Indiana, Missouri and Arkansas, known as Tornado Alley.

 Tornado - MSN Encarta
A tornado becomes visible when a condensation funnel made of water vapor (a funnel cloud) forms in extreme low pressures, or when the tornado lofts dust, dirt, and debris upward from the ground.
Supercell tornadoes are often produced in sequence, so that what appears to be a very long damage path from one tornado may actually be the result of a new tornado that forms in the area where the previous tornado died.
Tornadoes are most frequent in the Midwest, where conditions are most favorable for the development of the severe thunderstorms that produce tornadoes.

 Tornado Warning
The exact mechanisms that cause a tornado to form are still not fully understood, but the funnels are always associated with violent motions in the atmosphere, including strong updrafts and the passage of fronts.
Damage to property hit by a tornado results both from these winds and from the extremely reduced pressure in the center of the funnel, which causes structures to explode when they are not sufficiently ventilated to adjust rapidly to the pressure difference.
Tornadoes are most common and strongest in temperate latitudes, and in the U.S. they tend to form most frequently in the early spring; the tornado season shifts toward later months with increasing latitude.

 Tornado Alley Maps and Information
Tornado alley maps are all made up of a general area from data taken over a long period of time.
Tornado alley should be thought of on a more yearly basis also, since weather patterns can change, making some states harder hit one year versus others, like Illinois in 1925, 1974 and 2004.
While it may be true that tornado frequency may be highest in a small area in the US on a yearly basis, dangerous and violent tornadoes happen over many tornado alley sections within the US that may have prolonged droughts of tornadoes before being annihilated by large, long lived tornadoes again and again.
