Bridging the sociology of uncertainty and weather, this review paper provides a sociological examination of the weather forecasting enterprise in order to illustrate how expert decision makers negotiate high uncertainty. It begins with an outline of the literature on uncertainty and risk, particularly as it regards the modern experience. It then fleshes out and expands the discussion through an examination of weather forecasting practice. The final section reprises the theme of expert decision making under uncertainty, this time focusing on the communication of risk and uncertainty, and it concludes with a few thoughts on the future of the field.
