Answer: When the sky is clear or mostly clear overnight, the ground cools, and the warm air radiates away from the ground, up toward the sky. If the ground cools enough, dew then forms on the grass.
When it’s cloudy overnight, the ground retains more of its heat, and not as much heat is radiated away as it would be in a clear night. This moisture condenses into droplets, which fall as rain. As the rain falls, it evaporates, leaving behind a trail of water vapor. The trail is called a rain cloud.
