I'm familiar with how things usually go from this kind of position in terms of model output - critical changes to break us out of the rut tend not to be picked up at the longer range, with the models tending to maintain the status quo in the absence of a strong enough signal for something different.
In fact, last winter began with a huge blocking high across the UK, and during the last week of November and first few days to a week of December, the models had high pressure sticking around for the foreseeable with little sign of a breakdown. Long range models such as CFS and the Met Office ensemble sang from the same hymn sheet.
They could not have turned out to be wider of the mark.
So it really is best to sit back and let things lie until the models pick up on something that might change the game. Usually there are a few red herrings, but then along comes the real deal, after which it tends to escalate quite quickly.
It's sorting the red herrings from the real deals that makes detailed yet accurate longer range forecasting almost certainly impossible. The best we can reasonably expect to do is look at large scale forcing mechanisms and what patterns they look to be in favour of. It may also be possible to get some idea as to when certain patterns may transition into others, but this usually only gives a very rough idea.
Current model output shows no sign of the extreme Pacific/U.S. jet pattern of last winter setting up, instead featuring a steady progression of ridges and troughs through the U.S. in a fairly flat pattern which prevents cold pooling in the eastern U.S.
There is then, if anything, some suggestion of ridges becoming more dominant across the eastern U.S. (probably largely in response to some high-amplitude MJO forcing), which would be a total contrast to the situation that developed last December.
Let's just chill out, look forward to the weekend, then make the most of the widespread useable weather that looks to be on offer
