As it turns out, the formation of dew is linked to the amount of cloudiness in the sky at night. On a clear night the ground cools, radiating its heat away into space. When the ground gets cool enough, dew forms, like beads of condensation on a can of cold soda. If the sky is cloudy at night, however, the Earth's surface doesn't cool as much. Some of the heat radiates into space, but much of it bounces off the cloud layer and goes back into the ground. If there are lots of clouds, the ground won't get cool enough to form dew. The saying works because, chances are, all those nighttime clouds might also cause a rainstorm during the coming day.
