________________________________________ cold front passes?
____________________________________________________________________

Explanation:

For a warm front passing: Warm, moist air rises over cooler air. This causes gradual temperature increase, light to moderate precipitation (like drizzle, steady rain) over a large area, and a shift to warmer, more humid air after passage. For a cold front passing: Cold, dense air pushes under warm air, forcing it to rise rapidly. This causes abrupt temperature drop, often with heavy, brief precipitation (thunderstorms, showers), and a shift to cooler, drier air after passage.

Answer:

When a warm front passes: Temperature rises gradually, light - moderate precipitation (e.g., drizzle, steady rain) occurs over a broad area, and the air becomes warmer and more humid. When a cold front passes: Temperature drops abruptly, heavy but brief precipitation (e.g., thunderstorms, showers) often occurs, and the air becomes cooler and drier.
