What weather can be expected with a stationary front?

A stationary front occurs when two air masses meet, but neither is strong enough to replace the other. This often results in the formation of extensive cloud cover and prolonged periods of precipitation. As warm air rises over the cooler air mass, it leads to stable atmospheric conditions that favor the development of stratus clouds, which can bring consistent, light to moderate rain or overcast skies, sometimes lasting for days.

In contrast, other weather phenomena represented in the options, such as clear skies with occasional sun, intense thunderstorms, and rapid temperature changes, do not typically associate with stationary fronts. Clear skies generally occur in high-pressure systems, whereas intense thunderstorms are more aligned with cold fronts or warm fronts, where significant instability exists. Rapid temperature changes are characteristic of strong frontal systems or the passage of a cold front, not a stationary front where the temperature usually remains stable over time. This reinforces why long periods of clouds and precipitation is the expected weather with a stationary front.
