Thats far too out on the model to be worried about right now IMO
But the GFS has consistency on the potential December Cold Wave, this storm is only proving it, it needs to be watched very closely . . .
I feel like when you look at something that far out, it’s always better to go by the ensembles. I do agree that it’s something to watch though.

Iceresistance Yes I do agree it is something to be watched, but it is 12-13 days out, so expect changes

18z GFS is getting me strongly concerned for Early December

Light freeze Dec 8/9 near the Houston area, but that's no surprise.

by days 11-13 the 12z GFS is showing the potential for a huge arctic outbreak in early december, still far out but their definitely is a growing signal for this

Also 2 Major Central & Southern Plains Snowstorms, the entire State of Texas will go under a deep freeze if the 12z GFS verified.

That would definitely mean some seriously cold air for december, model support is starting to grow on to this arctic blast, will see as we get closer to that timeframe

Thinking ahead. If that does verify, how cold? Wondering if we will have rolling blackouts.
