An unseasonably cold and wet low pressure system will bring mountain snow and valley rain/snow mix to the Northern Rockies mid-week. Wet conditions will make already below normal temperatures feel even colder, with afternoon highs 10F degrees or more below normal for this time of the year. At this time, most of the valley precipitation is expected to be rain, though during the overnight hours it could turn to mostly snow allowing for light accumulations. The higher valleys of north-central Idaho (Elk City/Dixie/Pierce) and along the Continental Divide in western Montana, could see more snow accumulations with areas of snow covered roads. Right now, the passes mentioned in the graphic will see most of the impacts due to snow. Though the passes further north in western Montana could see light snow accumulations as well. More details and updates to come as they are resolved.
