Pleasant weather is expected to continue through mid-week across the Northern Rockies. There will be a chance for showers and isolated thunderstorms on Wednesday and Thursday. There is a 60 percent probability for a wetter spring storm Friday into this weekend! The immediate threats include up to a 20 percent chance for lightning, mainly in the higher elevations of the Clearwater and Bitterroot mountains mid-week. If the cold spring storm does develop, that will be a significant change to colder conditions, especially in the backcountry with snow levels ranging between 4000 feet to 6000 feet.
