What will likely be the biggest snowstorm of the season is upon us.  Snow will accumulate for days, but frigid air will accompany the snow.  A “pineapple express” plume of moisture is coming in from the Pacific.  At the same time, another surge of arctic air will come down from Canada.  Lots of moisture meeting extremely cold air will result in significant snow accumulation.  Snow will be persistent into the middle of the week.  There may be a few periods when the snow breaks, but snow and cold will be found in the state most of the week.  Persistent snow will really add up over the course of several days, and by Wednesday much of the state could have approximately 6-12″ with heavier amounts up to 16″ in the lower elevations.  The mountains could see upwards of 24″ by the middle of next week.  Significant snow and dangerous cold will make for a very tough stretch of weather here in Montana.
