This just proves exactly what hammerman has said..nobody knows. I took this extract from sunflower's link.
"For this winter, wetter-than-average conditions are favoured over central and southern Europe, although for the UK, there is approximately even chance of a wetter-or drier-than-average winter.
Last winter saw much drier-than-average conditions across northern Europe and all parts of the UK - much as last autumn's forecast had suggested. In the south-east of England this was the continuation of a long period of dry weather starting in November 2004, continuing through to the summer of 2006".
Talk about hedging your bets, even from the mighty Met Office!
