NBMv4 has these models/weights:

NBMv5 (parallel) is a bit different but the weights haven't been released. Pretty sure they removed SREF and added AI Models (like AIFS). They also do some different bias correction methods in v5 such as probability matched mean to achieve more accurate/unsmoothed outputs.

You can go to the NBM Dashboard, select the NBM run for version 4.3, select the parameter, and hour, and it tells you the models used in it. Them not using the Euro Op but using the GFS op is wild to me. As is using the oldest data from the Euro ens out of every model.

Completely agree with this. Simply because I still don’t understand. I’m a slow learner. Thank you, for posting as some are able to discern the fantastic information you provide. Can’t thank you and many others enough. Mean that very sincerely.
 
My first and only call map. Very not professional looking but my general thoughts. Dry slots are a thing but I think with all the dynamics at play plus great snow ratios the lower end who busts still get a few inches of snow.

I think Raleigh and Charlotte are golden and will each pick up their own maximum amount of snowfall. Then in those spots there will be an area that can get 10+ inches of snow. Those dotted areas can of course shift anywhere in those zones depending on where banding develops.

Let’s see how I do!

(This is NC only I didn’t give much thought to areas outside but I suppose anywhere outside of zone 1 will more than likely see 1-3)

CMC a good hit too, good trends at 0z tonight that's for sure. Now can we hold them through go time

The whole model progression has been pretty spectacular in my opinion for the Carolinas. We had some model runs to the SW, some to the NE, and they've converged on us now. And the 50/50 low hanging in and trending some SW was huge. All of that has been great. Now just the fine details.
 
You can look at the NBM Dashboard. It lists no OP Euro that I see, and 0z Euro ens members, and 6z GEFS ens members for 18z.

Is your list a list of included models? Because if so, it appears to includes numerous Euro ensemble members.
 
My first and only call map. Very not professional looking but my general thoughts. Dry slots are a thing but I think with all the dynamics at play plus great snow ratios the lower end who busts still get a few inches of snow.

This could be too light but generally I’ve always been high on totals ingesting all the data in. This just has the making, with great dynamics, to be something really special here. Can’t get better ratios for the Carolina’s. Add a coastal and upper low magic? Too many things can go right that can offset a few dry pockets here and there.
