In reply to george mc:
It's no good it only staying to Hogmanay! I only get to Scotland on the 30th of December... though if it's anything like last year (unlikely!) it'll be Shining Clough on Boxing Day again!
To be serious for a moment, no-one's forecast has a 'strong signal', surprising _unlike_ last year, where Mark Vogan had been predicting the onset of a 'real' winter for a couple of months before hand ("end of November"), and then got the day right two weeks in advance... mainly by looking at a combination of different people's forecasts. He'd also got the previous year's winter very well described.
For this year, currently, he's the only one to stick his neck out and say that the UK will still get another very significant cold and snowy spell; to paraphrase: most probably starting from mid-December and lasting until near the end of January.
There are some very, very cold conditions in Alaska and Eastern Siberia at the moment, but they are being 'offset' by our exceedingly mid Autumn thus far. Our previous 3 Autumns have all been very mild as well.
I'm watching all this with a lot of interest (and the knowledge that the coolant in my car needs its anti-freeze replacing!) I wouldn't say anything is 'odds on', but I am expecting, and preparing for, 'interesting' conditions again...
