What is the expected effect of a cold front following a warm front?

When a cold front follows a warm front, the expected effect is cooler temperatures with possible precipitation. This occurs because the cold air associated with the cold front is denser and pushes the warmer, moist air that has been lifted by the warm front upwards. As this warm air cools, it may condense and form clouds, leading to precipitation. This process often results in a shift in weather patterns, from the mild, stable conditions typically associated with a warm front to the more chaotic and dynamic conditions brought on by a cold front.

In this context, the cooler temperatures come from the intrusion of the cold air mass overtaking the warm air mass. The potential for precipitation is also significant due to the lifting of moist air and subsequent cooling. Thus, the combination of cooler air and potential rain or storms is characteristic of this sequence of fronts.
