Wintry 1/20 - 1/23 Winter Storm

Another view of how much the GFS has improved since a couple days ago

0Z CMC has nearly 0.50” of qpf here tomorrow night, but it just like other models has fortunately been slowly warming from run to run with the wetter conditions/western shifts of the main precip. At one point on older runs, Fri night was almost entirely looking to be at 32 or lower. Now it is looking to be a few degrees above 32 much of the night. Fingers crossed!

Per KCHS, they're going more towards the NAM thermal profiles on low level cold advection crashing SFC Temps a bit quicker than shown from other modeling (due to NAM performance of wedges better than most). Savannah probably escapes a lot of icing... probably up to .1" but if 00z and overnight trends continue, I really believe ice storm warnings may replace the current advisory in the Quad Counties in SC...
 
Wouldn't be surprised if blizzard criteria is met somewhere on the NC/VA coast, already gusting to 30-35 in some spots along the Chesapeake Bay and OBX
are warnings standard across most areas? I just read 25mph sustained meets criteria..
 
For my backyard, CMC has better lift in the mid levels(esp at 700mb height), but isn't as moist as the GFS. Still produces a little under an inch of snow here. If I could get GFS's moisture profile with CMC's UVV's in the mid levels, something could actually happen here tomorrow.
I know it hasn't been as cold leading up to the event, however remember is 2014 it only took an inch of snow to shut down northern GA.
