Wintry 1/20 - 1/23 Winter Storm

Not gonna lie tonight has turned out better than I expected, .5 still light snow and the back edge has been very slow to progress east, with some back building at times. HRRR wasn't that far off actually. Hoping a good sign for tomorrow
 
Oh okay. Can we coin a new term of getting WRF'd. I started to post this in the banter instead, but I mean it fits into the westward trend of the models tonight albeit the most extreme so far. ?

There’s no way that the WRF isn’t solidly cold biased. It is clearly colder than any other model. In addition, it was even colder in earlier runs, clear signs of cold bias. Also, it has much heavier qpf at least in my area vs all other models. I’m definitely tossing this lmao.

Models are slowly warming things here, which may be enough to keep out all ZR from here to the coast.

Oh I know, this is the same model that had us getting as low as 21 during last weekend's event.
 
I'm wondering if NWS Raleigh will upgrade the Winter Weather Advisories to Winter Storm Warnings for Raleigh and points west considering the model trends that have taken place tonight by 6:00 AM tomorrow?
I wouldn’t be surprised either way, but I really think they should upgrade a lot more of their counties to warnings in their update tonight. The potential for warning criteria snowfall is now there for much of their CWA and even if the technical warning definition isn’t met, even 1-2” of snow will be high impact given how cold it is. The roads will be a mess, so it’s not like the public will be crying foul.
 
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!

Edit for typo

On Spectrum 14 news one of the meteorologists was saying that there is the possibility that snowfall ratios with this storm could be as high as 15 to 1. That would up these amounts significantly.

Yeah, our local guys in CAE are saying a "flurry" possibly a dusting. heh.

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.
