3K looks the best for NC for snow, followed by the FV3, and then the NAM. NAM has more precip than the FV3 but it's also warmer. 3k has a ton of precip and is colder.
These models are horrible. No consistency between them and no consistency from run to run. Even the short range models go from 6 inches to 1 in less than 36 hours between runs and only 24 hours out from the start of the storm here. And the long range ones have been all over the place the whole time and still are with GFS still showing 5 inches here and the Euro barely 2.
