I think this is a reasonable look at what will happen, although for most, I'd be hesitant to go all in on 3"+. 1-3" seems reasonable for Greensboro, and I'd lean more towards the low end
There's a range of temps at which dendrites grow (which create very high ratio snows). Ideally you want the area of greatest lift, to fall within this zone to get dendrites. On tropical tidbits, the orange bars on the left tell you how much lift there is at that level.
Finally, a mythical unicorn storm like the unicorn storms of old.
I would say probably just due to the tendency of the Euro to spin up deep lows out of nowhere. The trough is digging like crazy, the only way this thing works:
The 6z models backed off a bit on rain totals. 2-4" has been a good forecast for a day or two now and still seems reasonable, although I wouldn't be surprised to see 6"+ somewhere
13% of winter's since 1920 in Greensboro have featured less than an inch of snow. I think we'll get there, but at this point I would be happy with anything at all.
