A front is an area of unsettled weather. In front of a cold front is warmer air. Behind a cold front is colder air. As the colder air meets the warmer air, the cold air rides over the warmer air and causes condensation. Rain happens. Since conditions are unsettled, winds blow. The warm air fights back. Sometimes tornadoes form. The cold front either wins and goes forward or collapses.
Temperature is lowered. Humidity is increased in a cold front.

When a cold front hits, usually the warm air rises.
Under these conditions the cold front will probably bring thunderstorms.
The temperature decreases.
Precipitation, usually in the form of rain, is a common reaction of a cold front when it meets a hot environment.
When a warm front moves into a cold front, the warm air gradually rises over the denser cold air. This can lead to the formation of clouds and precipitation. The warm air displaces the cold air, leading to a gradual increase in temperature and humidity.
When fronts meet from the opposite and collide, it is called an occluded front. A cold occluded front is cold air shoving under cool air at the Earth's surface thus the name 'cold occlusion'. The cold warm air boundary aloft is often west of the surface front. A warm occlusion is when cool air rises over cold air at the surface thus the name 'warm occlusion'. The warm-cold air boundary aloft is often east of the surface front. By Lisa Gardiner
a cold front
A cold air mass comes in under a warm air mass.
Cold air is denser than warm air. Which allows it to slide under that warm air and displace it.
