The air behind a cold front is cool and dry.
no
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.
Sinking air, combines with dry weather and only a few clouds are indicators of a cold front. Cold air is heavier and more dense than warm air.
Dry air is not absolutely necessary, but moist air is. Warm, moist air carries quite a bit of energy in the form of latent heat. This latent heat is the source of energy for thunderstorms, which are in turn what cause tornadoes. The thunderstorms that produce tornadoes usually form along a cold front or dry line. A cold front occurs when a cooler air mass pushes into a warmer one. The warm air, which is less dense, rises over the cooler air, which can trigger thunderstorms. The air behind a cold front is usually drier than the air ahead of it because cool air cannot hold as much moisture as warm air. A dry line occurs when a dry air mass pushes into a warm air mass of about the same temperature. Since dry air is denser than moist air, the moist air gets pushed up, which can trigger thunderstorms.

The four types of fronts change the weather on Earth. A warm front brings warm, humid air and a cold front brings dry, cool air. A stationary front does not move and have winds parallel to the front. An occluded front occurs when cold air overtakes warm air.
