The first tentative predictions for a white Christmas in London are starting to come through.
The Weather Action website is predicting a 50/50 chance of snow in the capital on Christmas Day...so either it will or it won't then. Great.
William Hill are not so sure, they're offering 9/2 on the chance of a flake or two, while Paddy Power are offering 6/1 that snowfall will be "officially registered at Heathrow Airport on Christmas Day".
Heathrow? Didn't it used to be the London Weather Centre?
