In a word: Yes.
Regarding the mist. If there was mist and sunshine the water would be evaporated and rise up into the sky and form clouds. The clouds when cooled become denser and the water falls from the sky. Thus we have rain. If there was moisture on the earth, there was rain. Period. You can't stop the water cycle, unless you are an all-powerfull omni-potent all-knowing god, of course and do it just for kicks.
