Ok, well looking at:
Temperatures - this met office probability thingy is saying that we have a 40-60% chance of it being colder than average BUT if you look at Europe it shows europe as being most likely to have a near average winter. So the cold wouldnt necc becoming from the east.
Precipitation - shows no weighting to any of the probability ranges - so it could be anything from more than normal to less than normal or somewhere in the middle!
The outer quintile categories are quite interesting.
GFS shows a fairly typical November this week, cooling down to widespread single digit temps for the last week in November. Right at the end of the month it hints at the atlantic winning again, so no prolonged blocking showing (which would lead to proper cold temps. However of course the battle between mild and cold can always be interesting along the leading edge in winter.
So to summarise. Nothing drastic showing up yet for the next couple of weeks, but if gfs were utterly accurate (which it wont be in this timescale) the end of the month could cause some brief fun. As for the rest of the winter, there arent really any strong signals as far as I can see for anything too exciting, but at the moment, the odds might be in favour of something cold, but who knows on the snow front!!!!!
