It's all relative though,isn't it.
Yes,if your looking for minus double digits with foot long icicles,hanging off the gutters,then your probably right.
But,if like me,you would be happy with a couple of snow shower's and an hours sledging,then no,winter's not over.
Feb hasn't even begun yet,plenty of time to see some white stuff.
People need to be realistic,this is the U.K,it will be mostly mild,most winter's.
One of the best snowfall's recently,here,was 28th feb 2004. Feb 28th is STILL, 5 weeks away,keep the faith.
