What is the typical change in barometric pressure after a cold front passes?

After a cold front passes, it is typical for barometric pressure to rise, often rapidly, accompanied by clearing skies. This phenomenon occurs due to the displacement of warm air by the colder air mass associated with the cold front. As the cold front moves in, the warm, moist air is lifted, leading to cloud formation and precipitation. Once the front has passed, the cooler, denser air settles in, resulting in a rise in barometric pressure.

Additionally, the rapid rise in pressure signifies the stabilization of the atmosphere, as the lifting action has ceased and the skies begin to clear. The associated change in weather conditions reflects this stability, typically transitioning to a period of improved weather with clearer skies. This behavior is a key characteristic of the atmospheric response to a cold front, distinguishing it from conditions preceding the front, where pressure might drop or remain steady, depending on other atmospheric influences.
