What happens to the pressure as a frontal system approaches and after its passage?

As a frontal system approaches, the air pressure typically falls due to the incoming warm air that is associated with low-pressure systems. This drop in pressure occurs as the front nears because the air masses are moving, leading to dynamic changes in the atmosphere. Warm air rides over cold air, reducing the pressure in the area. Once the front passes, the pressure begins to rise. This rise can be attributed to the arrival of cooler, denser air behind the front, as high-pressure areas begin to dominate the weather pattern following the frontal passage. Therefore, the statement indicating that the pressure falls as the front approaches and rises afterward accurately reflects these meteorological principles.
