A cold front brings in cold air. The cold air causes warm air to rise quickly. The rising air forms cumulus clouds. There is often heavy precipitation at a cold front.
When the surface position of a front does not move, a stationary front forms. In this scenario, warm and cold air masses remain in place, often leading to prolonged periods of cloudy and rainy weather in the area. The temperature differences between the air masses can cause the front to be associated with precipitation, but since it doesn't advance, the weather conditions tend to persist.

A front forms. The type of front depends on which air mass is advancing. If the cool air mass advances, it is a cold front. If a warm air mass advances, it is a warm front. If neither advances, it is a stationary front.
Air masses that are cold and forms over polar regions is polar. A cold front occurs when a cold air mass meets and displaces a warm air mass. A front that forms when a warm air mass is trapped between cold air masses and forced to rise is called a occluded front.

The cloud that forms along the leading edge of a gust front is called a shelf cloud. Shelf clouds often indicate strong downdrafts and changing weather conditions associated with the passage of a thunderstorm or squall line.

It forms a warm front. Along with this nimbostratus, altostratus, cirrostratus and cirrus clouds are formed.
A warm front forms when a warm air mass advances over a cold air mass, leading to the warm air gradually replacing the cold air. This process often results in steady, prolonged precipitation as the warm air rises over the denser, cooler air.
Tornadoes, hail and other forms of severe weather most often form ahead of cold fronts.
