What kind of weather is likely to occur at a cold front?

At a cold front, the interaction between cold air and warm moist air can lead to significant weather changes. When a cold front advances, it forces the warmer air to rise rapidly. This rising air cools and condenses, often leading to the formation of cumulus and cumulonimbus clouds. These conditions are ideal for short, intense rain showers and thunderstorms.

Typically, the precipitation associated with cold fronts is brief but heavy, often resulting in dramatic weather changes over a short period of time. Following the passage of a cold front, there is usually a notable drop in temperature and an increase in clear skies, which is a stark contrast to the turbulent weather that precedes it.

This phenomenon explains why the response indicating short, heavy rain and thunderstorms accurately captures the typical weather associated with cold fronts. The other options suggest weather conditions that do not align with the expected behavior of cold fronts, such as clear skies or warm sunny conditions, which generally characterize post-frontal weather rather than what occurs during the frontal passage.
