As warm air is lifted over advancing cold air, itself cooled as its pushed away from gravity's pull at the Earth's surface, the water will begin to condense into clouds and precipitation will form, usually of the "showers and thunderstorms" variety.
When cold air masses push against warm air masses, a cold front is formed. This results in the warm air being forced upward, leading to the potential for thunderstorms and other severe weather patterns.
A stationary front occurs when warm and cold air masses remain in the same place, with neither one displacing the other. This can lead to prolonged periods of precipitation and unsettled weather as the boundary between the two air masses wavers back and forth.
The boundaries between air masses are called front. The types of air mass and movements involved determine the type of front. Warm front: a warm air mass plows into a cold air mass. Cold front: a cold air mass plows into a warm air mass. Stationary front: The warm and cold air masses move little relative to one another. Occluded front: A cold front catches up with a warm front, sending the warm air mass aloft. Dry line: a dry air mass plows into a moist air mass.
A stationary front typically involves three air masses of different temperatures - warm air, cold air, and cool air. This front occurs when a warm air mass is positioned between a cold air mass and a cool air mass, leading to little to no horizontal movement of the air masses.
When two air masses collide, the formation is called a front. Fronts can be warm, cold, stationary, or occluded, depending on the characteristics of the air masses involved.

Front
The point where these two air masses meet is called a front.If cold air advances and pushes away the warm air, it forms a cold front.When warm air advances, it rides up over the denser, cold air mass to form a warm front.If neither air mass advances, it forms a stationary front.
The boundary between two air masses is called a front. A warm front develops when a warm air mass pushes against a cold air mass. Rain usually occurs in a warm front and if temperature is low enough, snow falls.

1) Warm front - warm air mass replacing a cold air mass at ground level. Typically shifts wind southeasterly to southwesterly. 2) Cold front - Cold air replacing warm air at ground level. Tyoically shifts southwesterly to northwesterly 3) Stationary front - Equal amount of energy between warm and cold air masses creating a "stalemate".
A stationary front typically involves three air masses of different temperatures - warm air, cold air, and cool air. This front occurs when a warm air mass is positioned between a cold air mass and a cool air mass, leading to little to no horizontal movement of the air masses.
