Few flakes flying around here just north of Fayetteville in Linden (northern Cumberland County)

RAH update, mentions the updates to warnings would later if done .NEAR TERM /THROUGH TONIGHT/... As of 930 AM Friday... Just minor changes this morning as we await a full suite of new 12z- initialized guidance. Observational datasets confirm the near term forecast trends. The latest surface analysis shows the frigid high nosing strongly down through central NC with plenty of dry air advection, including single-digit dewpoints just to our N. Skies are just cloudy, with radar showing spotty elevated returns across the S half, although most of this is likely not reaching the ground given the somewhat dry subcloud layer noted on 12z soundings. Will maintain low chance pops across the SE well into the afternoon, before trending pops up with a NW expansion as we approach the evening. Any changes to the advisory or warning will wait a few more hours when further high res guidance can be fully considered. Expect temps to hold firm or rise just a degree or two today, yielding daytime highs of 27-34. Current brisk winds from the NNE and NE with occasional gusts to around 20-25 mph will persist through the day as the dense air pours in with a strong ageostrophic component, which will keep wind chills in the upper teens to mid 20s for much of the day. -GIH

I am not sure that having those two in your camp vs GFS/NAM is a great position to be in, I feel your pain

GFS is trying for March 1st

1960, 1980, 2000... Continue that trend....we are due ! Not all were March but big snows those years

Funny, all of the analysis I have seen so far say it is colder

It will be interesting to watch those actual dew points in comparison to where the NAM says they would be. They look to be ahead of schedule and lower than predicted off to the NW. Mt Airy shows a dew point of 11 as of last report on NWS

We need some of the lower dew points to keep filtering down into central NC. DPs still in 30s Raleigh and south, but 20s to even single digit DPs off to the NW of there. That is the critical piece I will be watching to get an idea of how well the cold air is working in. Obviously not too far to our NW

ABC11 (WTVD) says the southern part of central NC is the wildcard depending on how fast it changes over from rain/mix to snow. The comment was that it could be a bit more accumulation than shown because the timing in that area is hard to nail down and will have plenty of moisture on hand.

Radiational cooling will do wonders for surface temps, I am hoping it will clear out some and allow that

But also can lead to more of a warm nose with a more amped system

ABC11 (WTVD) actually showed the output from the NAM but discounts the amounts. They say what is important from the NAM is that the main area with a threat of the most snow lines up fairly well with other models. Still conservative at 1" or less, but did say that a large area east of Raleigh has a 40% chance of 1" or greater.

But it was record cold in place PRIOR to the snow, which makes all the difference down here

RAH not biting: Mid and high level moisture will increase rapidly on Thursday ahead of a positively tilted trough digging through the Midwest. Precip will spread along the stalled frontal zone over the SE US, with cyclogenesis induced off the SE coast. Models continue to trend a a bit closer to the coast with the surface low bringing more moisture inland. The low is still relatively weak, however, and moves east with the digging trough. The bigger question is whether or not the arctic air associated with a 1045+ mb high over the central US will spill across the mountains in time to cause a mix of rain and snow or changeover to rain. The high is not in a favorable location for the dense cold air to make it into NC very quickly...likely having to filter across the central Appalachians and south through VA...and so the probability of probability more than a rain/snow mix appears very low at this time. If there is an opportunity for phasing of sufficiently deep moisture/omega and cold air, it would be north and east of the Triangle, which is where the outlier EPS solutions lie..while the the GFS and GEFS appear to be too aggressive with with cold air.
