What is the Met Office definition of a white Christmas and will it snow this year?

The Met Office defines a 'white Christmas' as a single snowflake being observed falling anywhere in the UK on Christmas Day.
There is no significant snow forecast for the current period, with mild westerly conditions bringing a mixture of sunny spells and rain.
The long-range forecast indicates changeable and unsettled conditions with low-pressure systems dominating, bringing rain and strong winds, with snow likely confined to high ground in the North.
The Met Office states it is too early to predict if there will be a 'white Christmas' this year, with clearer forecasts typically available a week before the day.
Historically, over half of Christmas Days since 1960 have technically been 'white Christmases', but widespread settled snow on the ground is rare, having only occurred four times since 1981.
