Either the models will be totally wrong or this will be just a typical Northern Mountain storm. The models have consistently been showing flurries at best for Durango and most of La Plata County. Telluride, Red Mountain and Silverton will have the best chances of accumulating snow with 4 to 10 inches if they are lucky. The storm has been categorized as being moist, but if it is, the models are downplaying that parameter and, most of the moisture will ring out in Idaho and Utah. So the only factor worth talking about is the cold, which will help for maybe a quick couple inches or a heavy dusting at Purgatory and mid-elevation areas with 15 or 18-1 ratios.
I will update early tomorrow, the first flakes should not arrive until the afternoon at the earliest.
