It's funny - I know people who hate cold, but would much rather spend a winter in Canada than the UK, because at least they get snow to lighten the mood - and a good deal more in the way of sunshine. There is nothing redeeming about a mild winter in the UK - it's just dreadfully depressing, with a good chance of rain but nothing else. An average winter is usually bad too - and even cold months are pathetic.
The only time I ever want milder than average weather in winter is if it's February 1998 2.0 with temps in the high teens and sunshine - none of this mild, drizzly gunk we have now - and if it's a choice of a very wet, cloudy but mild February 2011 or a very cold, dry and sunny December 2010, the choice is obvious.
Speaking of February 1998, Leeds had an average high of 11.6C! Truly remarkable - would be interesting to see it again.
That being said, if this winter does turn out milder than normal, I won't care much. I thought a winter like 2013/2014 would drive me nuts but in reality I just wasn't bothered.
