What type of conditions can be expected after a cold front has passed?

After a cold front has passed, it is common to experience clear skies accompanied by gusty winds and cooler temperatures. This transition occurs because the cold front displaces warm, moist air, causing it to rise quickly and cool. As this happens, the humidity generally decreases, leading to clearer skies as the clouds dissipate. The rapid change in temperature can also cause the air to become more unstable as it cools, which may manifest as gusty winds due to the density differences between the cool, dense air behind the front and the warmer air it replaces.

The other conditions listed do not typically manifest right after a cold front. For instance, low clouds and reduced visibility are more often associated with warm fronts or various types of weather systems that bring moisture and instability. A fast-moving squall line with thunderstorms usually occurs ahead of a cold front rather than after it, as thunderstorm activity is stimulated by the lifting of warm, moist air prior to the frontal passage. Finally, stable atmospheric conditions are generally found behind warm fronts, where air remains relatively undisturbed, rather than in the wake of a cold front, where the air typically becomes more turbulent and dynamic.
