Which weather change is expected during the passage of a warm front?

During the passage of a warm front, one of the notable characteristics observed is that the pressure levels off as the front approaches and begins to move through. Warm fronts are associated with a gradual increase in temperature as warmer, lighter air mass replaces cooler air. As the warm air moves in, the pressure changes will stabilize for a short period, which is why you see a leveling off of pressure readings.

Additionally, this phenomenon typically brings a slow and steady lift of warm air over cooler air, often resulting in widespread cloudiness and prolonged precipitation. This gradual transition contributes to a leveling of the barometric pressure before it begins to drop again after the front has fully passed.

Other weather changes associated with warm fronts can include increased humidity and cloud cover, as well as a rise in temperatures following the front's passage. The options regarding gusting winds, sudden temperature drops, and a sharp decrease in visibility are not characteristic of warm fronts; they are more related to cold fronts or other types of weather systems.
