I’m not trying to be a Debbie, but it has to be able to couple to the troposphere. I have seen nobody talk about that, only about how there’s a split. If you ask me, it’s a bit misleading… And then I saw one person talk about it could lead to a very sharp cold snap later in November. But that can happen regardless.
Polar Vortex splits are meant to adjust the large scale pattern for awhile, not two days. All the stuff I’ve seen just seems very misleading to me and more of click bait type stuff.
The irony is that the pattern that helps cause the split will lead to a lot of CONUS warmth. Judah actually agreed on that. This split would also have to fight off Nino forcing which may make it harder to couple to the troposphere.
We could see a split have more meaningful impact as @40/70 Benchmark had alluded to come mid winter and beyond. But right now, many energy mets that I know are not sold on this being much or anything.
