According to this...just enough to cause some minor slick spots as 2m Temps crash for this area.
 
GFS 18z is just tiny lil baby steps for past 3 runs catching up with the NAM, every run a tiny bit more and a tiny bit further east every run... before it's squashed
 
The NAM is good trend! Yes! Very happy here in Columbia! Never trust LR models inside 50'ish hours. Barely trust them inside 340.

Which model got the early December "Thumper" correct, and/or did the best with it? I forget

I believe NAM was first to show heavy/higher accumulations then GGEM. Then they adjusted further NW with the heaviest band as we got within a day iirc

Atlanta BUFKIT leaves much to be desired.

Pretty sure this is right. Makes sense that it did since high res, at least in theory!
 
The nam is much slower vs other guidance when it comes to final pushing whatever precip there is to the south

I would love nothing more than this to sneak up on us all and give us a little New Years surprise
