UK looks like mostly rain for NC and ice for the northern counties, but somehow ends up with this.

Looking at this more closely, this 12Z Pivotal UK map has 2.5” of snowfall at RDU. Based on 850s, RDU gets no snow, ~0.2” of qpf as sleet, and ~0.5” qpf as ZR. Based on that, that’s ~0.6” of sleet (and no snow) vs this Pivotal map’s 2.5”. The SE/S portions of Pivotal UK snow maps are often not a reliable indicator of what the UK is actually generating. Algorithm issue at Pivotal for the UK snowfall maps is the problem.

Euro drops about a foot here. Sure wish other guidance would catch onto that 

And unlike some other snow maps, these WB 12Z Euro Kuchera maps look legit based on the 850 mb 0C line. There’s a short period of non-snow just N of the NC/VA border in your vicinity when 850s go >0C (centered on 6Z of Feb 20th), but otherwise it is snow.

My hunch is this turn more and more into a classic for NC as we see precip begin to increase back further west while we also see a classic turn to snow on the backside of the storm.  Take this with a grain of salt and only for similarity purposes, but it reminds me a bit of March '93 in the way I'd expect precip to transition through the storm.  NO, I'm not saying this is anything like March '93, on a similarity in the precip and the way I beleive the storm may begin to strengthen a bit early and wrap in more cold air which is there for it to tap into.

My .02 is that given model agreement for days now on a significant storm of some type for the area (and likely a high impact one for areas that get below freezing), and we’re only 5 days out, this probably deserves a thread since it’s hijacked any chance of discussion about the upcoming pattern, which honestly looks like we might get another chance before March.
