As a winter storm progresses, the large wedge of warmer air between the warm front and the cold front gets narrower. The cold front travels faster than the warm front, and beginning near the low-pressure center of a mature storm, it eventually overtakes it. This new boundary is called an occluded front. On one side is cold air from behind the cold front. On the other is cool air that the warm front was flowing over. Above the front is warm air that has been cut off from the ground.
