Pretty substantial shift south with the 850 low on the Euro as well

yeah thats the catch 22 with a quicker, weaker ull

One more of those and suddenly we back
Elevation is key imo look at Western Burke Eastern McDowell countys the 6 in line is where 1400" starts.

True, but even before the cold pool moves in the NAM is way stronger with 925mb cold air supply. If you click on soundings pretty much everybody is well below freezing at 900-950mb Saturday night even with a well above freezing raging warm nose above that.
If that low level cold air feed is real on the NAM it has big implications for snow reaching the ground and sticking when the cold pool moves over head Sunday morning.
Of course to some degree I think the stronger/more amped solution of the last NAM run goes hand in hand with strengthening that 925mb low level jet so it makes sense... but the NAM has been better/colder with it even on the runs that had a further Southeast and weaker low solution.
really like this one for the most part if you're in the mountains or have any sort of decent elevation, and should be a nice sugar rush for the ski resorts. these ratios will probably suck no matter how you cut it so take a solid 30% off or more off those snow maps
also don't discount whoever is directly below the cold core- that's where you'll find your surprises (ie atlanta picking up a slushy 2 or something like that)
for everyone else, don't think this is the storm for you, good luck next time (or next year)

I'm probably stuck with heavy rain while the western part of the county may get in on some heavy snow. But definitely Fancy Gap will do good at 2000 feet. I would be happy if I could just see some huge snowflakes mix in, that would be a win in this awful winter!

Euro is very close to having an all snow sounding from start to finish in the Northern Upstate. The weaker solution keeps the 700-800mb warm nose at bay before the cold pool moves. It's sketchy at best with the early precip out of ahead of the low with a near isothermal sounding all the way up to 700mb, but interesting none the less.

GFS was similar with the Euro for the all snow solution for the northern upstate. Boundary layer issues with it, but hoping the NAM is seeing that evolution better. This is a sounding for Pickens,SC at 1am just as the precip has started.
Come on now frosty you've said this before and always come out ok. You'll definitely see some backend flakes Sunday morning.

Really not much disagreement with the 500mb low placement now. They just disagree a bunch on the strength/temp/precip details.
Euro is the furthest S/E model now.

IN NC, all the accumulating snow will be 77 and West, anyone east of there may see some flakes for a time but no accumulation IMO. Far western SC and a small part of N Ga has a shot too

Through 36 hours on EPS more stream interaction
an issue is that there's not a single place with a lot of room for error since the preceding airmass is so mild
even on the colder GFS, this is not a sounding that inspires confidence for boone as things roll in. any adjustment to a weaker ull pushes this setup to even more marginal and narrows the snow window for a lot of folks.
just trying to keep expectations in line, even for the mountains we're going to be dealing with a lot of crosswinds (figuratively... and literally?) while trying to land this plane
Nice Euro run. Delicate situation we have here in the upstate. I’m not all in until I see chicken feathers in tree tops.
I actually hadn't looked at the NAM sounding for your location but after doing so this shot of WAA with the initial surge of lift is not what you are looking for as its likely to warm the 825-875 layer until the +2-4 range. Move this 50 miles to the SE toward the euro suite and you are golden otherwise it's rain/IP even with the colder 925s

EPS and the euro control run definitely good for WNC. Moved everything SE a good bit.
