An Atmospheric River is targeting Idaho for the weekend!
After weeks of dry, cold weather, our pattern is about to change as tropical moisture gets drawn into the jet stream to bring significant snow to Idaho's mountains.
I expect everyone to see snow on Friday and if it comes early enough in the day there will be some light accumulation in the valley along with slick roads but warmer temperatures will change snow to rain below 4200. I am concerned about the cold air stuck in the valleys. This may cause the snow to be slow to change to rain on Friday and there is a slight chance of several inches of snow in the western, lower Treasure Valley before changing to rain as warmer air moves into the region. Rain has a slight chance of turning back to snow mid-next week.
Significant snow of 1-3 feet will fall in the ski areas between Friday and Tuesday morning!
