It just continues on. A cold front is a large scale weather pattern often over a thousand miles long. Tornadoes are tiny by comparison and don't really affect large scale systems.
mostly cold fronts
Temperature is lowered. Humidity is increased in a cold front.
A tonado develops once two different air masses where to meet such as a cold front and a warm front
Stationary Front

Not usually. Tornadoes are usually associated with cold fronts or dry lines.
A tornado forms
A tornado is typically associated with a cold front, which is the leading edge of a cooler air mass pushing under a warmer air mass. The clash of cold and warm air can create the conditions necessary for the development of tornadoes.
When a cold front hits, usually the warm air rises.
Tornadoes most often form along a cold front.
