I’m not buying the long range NAM. I’ve noticed a clear bias with it being too wet. As much as I want it to be right..

It’s actually been to dry recently

Would that be snow in the upstate or is it to warm
Likely too warm but won’t know until the day before.

Since the “upgrade” it’s been too dry.
NAM reminds me of a more north version of the March 12th, 2017 snow event, also the one from early March 2014, and those storms trended better in the 4 days leading up to it, just don’t think snow will be that far south 
... damn you 84 HOUR NAM .... DAMNNNNN YOUUUUUU FOR DRAGGING MY CHIPS IN

Nam is normally cold biased at the surface so we gotta take that into account, but this in my opinion is the best shot at seeing snow fall in NC outside the mountains so far this winter
What makes the run of the nam exciting was how temps were cooling during the event and 850s were cooling down a good bit along with the surface temps, NS energy phasing helps with that
Hour 81 (just west of CLT)
hour 84
We still have a long way, but this one has me a bit excited that I least see a few snowflakes fall in this dumpster fire winter

Here’s where the 18z ICON finished. It’s at 18z on the 31st so technically this is the correct thread to post this in 
GFS definitely trending to send that thing negative tilt sooner..
If that were to verify, it looks like our area (RDU) would be good for wintery precip. At hour 84 surface temps would be ~34 with a dew point ~22. Surface winds would be from the due north, so no worries about warm air pushing in. 850 temps ~negative 4. At least this is something to finally track.

Chapel Hill putting the chips in.

This is great to see, w/ a stronger s/w we not only have a stronger system w/ more precip to work w/, but as the wave slows down, this allows for more separation between it and the vortex over Atlantic Canada, enticing a more intense storm to lift north in later runs. The increase in northern stream interaction also injects more cold air into this setup as we close in on verification. Hopefully this continues.
Obvious to see where this is going, soundings are noice just north of the precip sheild, supportive of snow, classic case of the north/northwest trend here with stronger energy/more digging 
GFS much closer this run. Comparing the Nam and GFS, if we can see just a little more energy at H5 in the N/S (Circled region), this could put frozen precip in areas.

Much better than the last run

Could Columbia possibly get in the game? At Day 4
Also this system moves in over night .. we love to see it
