After the recent cold snap and a dusting of snow in some places last night, a few more of us are pondering the possibility of a White Christmas.
From the bookies perspective, the definition of an official White Christmas is a single flake of snow to fall between midnight on Christmas Eve and midnight on Christmas Day.
Most UK cities have their own designated site to watch for potential snow.
Already lying snow does not count. It has to be falling snow.
Our last White Christmas was in 2010, when 83% of the Met Office national snow sensors reported falling snow. In contrast, last Christmas was remarkably mild.
In the last 52 years, snow has fallen on Christmas Day 38 times. But statistically there is a higher chance of snow at Easter rather than Christmas.
It's a little too early to give precise predictions on the chances of falling snow this year - ask us again in a couple of weeks.
In the meantime, here are the latest White Christmas odds (via William Hill).
- 3/1 Aberdeen (Pittodrie)
- 4/1 Edinburgh (Castle), Glasgow (Cathedral)
- 5/1 London (Buckingham Palace), Belfast (Airport), Newcastle (Albermarle)
- 6/1 Birmingham (Bullring), Leeds (William Hill Head Office), Liverpool (Albert Docks), Manchester (Granada Studios)
- 7/1 Bristol (Filton), Cardiff (Millennium)
Or if you prefer the idea of an outsider, the odds of the Thames freezing over is currently 100/1.
