What happens when an active cold front overtakes a warm?

When an active cold front overtakes a warm front, it can lead to the development of a more complex weather system known as an occluded front. As the cold air mass pushes under the warm air, it forces the warm air to rise rapidly, often resulting in significant cloud formation and precipitation. This process can produce storms, including thunderstorms and heavy rain, depending on the moisture content and instability of the air masses involved. The occlusion can eventually lead to the dissipation of the warm front as it gets lifted away from the surface.
