Answer 1

Basically they need a moisture source and that is accomplished in Missouri let's say when moisture comes in from the Gulf of Mexico.   That moisture is carried along by low level winds and provides the needed moisture.

They occur with warm to hot surfaces temperatures and cold air aloft.  Both of those conditions cause lifting.  Lifting causes clouds and those clouds turn into thunderstorms and tornadoes when conditions are right.

Answer 2

im pretty sure its when the wind current starts blowing in all directions, im not sure what causes the wind to do that though

Answer 3

As the meso cyclone approaches the ground, a visible condensation funnel appears to descend from the base of the storm, often from a rotating wall cloud. As the funnel descends, the rear flank downdraft also reaches the ground, creating a gust front that can cause damage a good distance from the tornado. Usually, the funnel cloud becomes a tornado within minutes of the rear flank downdraft reaching the ground.
