If one is to forecast based simply on model derived "precip-type", the mountain will get thumped to the tune of up to a foot of snow between midnight Saturday and midday Saturday. The weather service isn't quite buying that however and I am a bit skeptical myself. It's a key question however, if the changeover occurs quickly due to the intensity of precipitation, MRG will do very well, scoring upwards of a foot of snow by late morning. I tend to think the changeover to snow will be a bit slower and thus accumulations will be in the 5-10 inch category. Snowfall will be wet and gloppy overnight but could turn powdery as temperatures above the mid-mountain fall to sub-25 by around 8 AM Saturday.
There are two additional changes for light snow from weaker disturbances or areas of moisture. One Sunday morning could result in an additional 1-4 inches. Another later Monday is more of the overrunning warm advection variety and could result in a few more inches.
