What type of weather is typically associated with a warm front?

The characteristics of a warm front are typically marked by gradual changes in weather conditions. As the warm front approaches, temperatures rise steadily, and cloud cover increases, signaling the transition of air masses. This phenomenon occurs because warm air, which is lighter than cold air, gradually rises over the colder air mass. This ascent often leads to the formation of layered clouds, primarily stratus and nimbostratus, which can produce prolonged periods of light to moderate rain as the warm air cools and condenses.

This gradual transition is a stark contrast to more severe weather patterns associated with other phenomena, such as sudden drops in temperature or rapid thunderstorms. In the case of a warm front, the change in weather is smoother and generally does not result in violent storms or immediate adverse conditions. Therefore, the choice highlighting gradual increases in temperature and cloud cover, followed by potential rainfall, correctly reflects the typical weather patterns associated with a warm front.
