The 2014 storm was a thing of beauty. I too remember monitoring the radar. The first thump came through during the evening. The following morning I remember my vehicle completely buried in 20 total inches of snow. The ULL went right through the heart of our area and the rate of snowfall was ferocious. Picture of that storm below.
In regards to this storm for the Roanoke Valley, I have that gut feeling just as Disc does. The mixing, the way the moisture is positioned. It just screams something like 4-7 inches of a snow/sleet mix. A nice front end thump in the morning Sunday, and then sleet in the afternoon to top it off before the system exits our area.
