It snows in south central TX every year and Mexico and in the Southwest. Very happy for those people. I don't see any mechanism to direct arctic air into the southeastern US on a sustainable basis right now. Maybe something gets well-timed for the Triad, mountains, VA, and extreme northern GA, AL, and for TN. That's pretty typical too. They can work much better with stale air and marginal dew points.
But for a large chunk of the SE, south of those areas, we're going to need something more than an in and out cold shot if we are to get something other than a thread the needle scenario. Until we start to see arctic highs showing up, you can post ensemble maps showing blue streaks until you're blue in the face, but it's just going to be more cold rain for most.
Maybe we get a late blooming phased coastal that crashes the column and we snow. Otherwise, give me a big high pressure. Until I see that, this isn't all that great of a pattern, IMO. And I certainly don't think any of that is nonsense.
