what is a warm front

A warm front is a transition zone that forms when a warm air mass advances and overrides a retreating cold air mass. This results in a gradual lifting of the warm air over the cold air. As the warm air rises, it cools and condenses, leading to the formation of various types of clouds and precipitation. Warm fronts are typically associated with gentle, steady precipitation and are characterized by a gradual increase in temperature after their passage. They are part of the broader family of weather fronts, which are boundaries between different air masses. Warm fronts are known for causing weather events such as rain, snow, and sometimes thunderstorms, depending on the atmospheric conditions. The first clouds that indicate an approaching warm front tend to be mostly high cirrus at first, changing to cirrostratus as the front approaches
