Introduction to Fronts

A front is where two different air masses meet. Depending on the circumstances different weather may occur. In the North America fronts travel from west to east. Your weather conditions depend on the front heading towards you at the time.

Types of Fronts

There are four types of fronts:

Cold Fronts, warm fronts, stationary fronts, and occluded fronts.

Occluded Front

An occluded front is formed when two cold air masses trap a warm air mass above. The cold air masses stay below because their more dense than the warm air masses. Occluded fronts usually bring light rain or snow.
