What type of weather would a "warm front" typically bring?

A warm front is characterized by the transition of warm air moving in over colder air. This atmospheric phenomenon often results in a gradual increase in temperature as the warm air rises and cools, leading to cloud formation and precipitation. The precipitation associated with a warm front tends to be steady and prolonged, rather than heavy or intense, creating a scenario of steady rain rather than sudden storms.

As the warm front advances, it typically brings an increase in atmospheric moisture, which contributes to the likelihood of rain. The warm air will continue to rise as the front progresses, and this can lead to overcast conditions. Following the passage of a warm front, temperatures usually rise due to the influx of warmer air.

The other options do not accurately describe the effects of a warm front. Sudden drops in temperature with strong winds are more typical of cold fronts. Clear skies and high pressure generally follow after the passage of a warm front rather than being associated with it directly. The notion of cold air sweeping the region aligns more closely with cold fronts, which bring in cooler temperatures following their passage. Therefore, the correct depiction of weather associated with a warm front is the gradual increase in temperature accompanied by prolonged periods of rain.
