What weather phenomena are commonly indicated by a cold front?

A cold front is typically associated with a rapid change in weather conditions. As a cold front approaches, warm air is lifted over the advancing cold air, which can lead to the development of cumulonimbus clouds and thunderstorms. Consequently, you often see a sudden drop in temperature as the cold air moves in, along with an increase in wind speed and changes in precipitation.

The presence of thunderstorms is particularly notable with cold fronts due to the instability created by the rising warm air, which can lead to heavy rain and even severe weather. This characteristic of sudden temperature resets and the likelihood of thunderstorms makes the choice highlighting a sudden temperature drop and the potential for thunderstorms the accurate representation of what to expect with a cold front.
