The moisture is fine on the ICON...it's the cold air that's having a hard time.
A lot of that will depend on how quickly the changeover can occur. I like that bullseye near Jackson, MS.
Yeah, I know. If it's anything similar to the system this time last year, the changeover will likely be quick. My memory is a little foggy, but I don't remember us getting a lot of rain prior to the changeover here, but I could be wrong. I know we dropped from around 40 into the 20s within just a few hours though. The biggest difference between this one and last year will be timing. Last year the precip moved in late evening (after 7-8pm) and this so far will be mid afternoon.
Gfs looks like the 12z version of itself, energy slightly slower
0z GFS has more moisture this run.

Should be a good run coming up based on hr. 102
No wonder we cant get a wave of LP to develop on the fropa ?
Nice hit.

CMC is not lacking with moisture, not sure about temps yet
It can take a longer time for the colder air to "reach" over the mountains.
Another good hit by the GFS.

Widespread 1-3 inches in MS/AL. Western areas of ATL metro gets a nice hit...eastern areas mostly shafted...cold air wasn't issued as much as a lack of moisture.

Based off this I better get ready to pack my bags on Sunday (if I were allowed to go):
2-0 00z model suite off to a great start.
0z GFS was a great run for this storm. More moisture, better push of arctic air.
Where you headed? Lafayette doesn't look like a sweet spot on this run

widespread 3-4 in here in the north
Nice widespread 2-4 inches for everyone using a 10:1 snow ratio.

There's a Lafayette in Georgia, it's where my mom's side of the family has lived for years and years, and that's NW Georgia.
and yeah, the 850s are perfectly fine at 120, but because the moisture is starting to dry up, in some areas it's simply light rain.

Oh Canada 
Wow that would be like a 6-8 inch snow using a 15:1 ratio. That would neat.

If (downtown) Asheville gets 5" out of an arctic fronal passage, but can only manage 4" of snow and sleet from the overrunning storm we had in december, I'll be happy, but confused.
2 different possibilities , cmc is better for the Carolinas,cmc allows a wave to develop due to the pv lagging behind a bit 
3-0
Great start tonight.
CMC also comes out with "Round 2 from a second wave by 2/01 for some of the same areas, but not as far south with the snow.

CMC's precip maps look better than what the snowfall map is showing. Hmm...still think this can trend better here. Can't wait for FV3 and Euro tonight.
What time is the euro coming out tonight

I am officially excited for this system. If it can tap into the gulf we an really increase our moisture returns. With the frigid temps behind it, this could become a very big deal.

FV3 is much lighter and is mostly light outside of parts of Tennessee. Might have something later based off what I'm seeing but I wouldn't relate it to this.

This is gonna be an extremely fast moving system . Despite a little higher ratios than normal there will be a ceiling as to how much snow can actually fall. I’m still firmly in the camp of 1-2 inches
