It's slightly mad to start a thread before we've even hit October, but I know that many are quite anxious about the prospects of cold weather this winter, so I'll start it early.
The usual caveats apply : I'm not a professional forecaster. I often get things wrong! Please don't make decisions on what I say - especially ones that have safety or financial implications.
This far out all we can talk about is the balance of probabilities, we can't make predictions. And as we know with probability, the improbable happens!
At some point this thread will start to get confusing as everyone gets excited about christmas weather. I'll start a separate, specific christmas thread about five weeks before Christmas.
