The only thing cold weather has done to my bow, is made it cold. The dampeners may be away from the string. Do u have your bow poundage all the way down? If u have it towards the low end, say 60lbs. out of a 70lb. bow, the length becomes longer in draw and the limbs angle more, therefor moving the dampeners slightly away from the string. They may just be bouncing off. Other than that, i cant think of anything. Try a little wax on the dampener, like bowstring wax. Tell us what happens.
