It affects the hunter more than the bow. I've never seen a difference in how the bow shoots just from being cold but adding heavy jackets, gloves, balaclavas, neck gators... all change how the bow is anchored and therefore, the point of impact. Be sure to practice with the actual clothes that you'll be wearing and if you're consistantly hunting in cold weather you may want to consider dropping 1/2" and 5#'s of draw from what you would typically shoot in warmer temp.'s.
