According to the CFS forecasts this winter is looking like a less interesting (less cold) version of last winter! I generally trust the CFS forecasts and it has done well in the last couple of winters. However, in my opinion, it's performance has dropped in recent months and autumn so far is a good example of this! Up to early August, it was predicting a below average Septemper for western Europe, including the UK, only to water down it's forecast closer to the month and as we know September ended up well above average. Similarly, it was going for a below average October and it has recently shifted to an above average month. Therefore, I don't trust CFS as much as I was until a few months ago.
As for the ENSO forecasts, La Nina, doesn't look anywhere near as strong as last winter. In fact, El Nino is one of the 2 models that have the most negative index with the other models going for a weak to moderate event.
