The UK could be set for a White Christmas as plunging temperatures could bring snow and sleet.
While conditions are set to be mild for the rest of this week, things are predicted to change in time for the big day.
Forecasters say temperatures will fall to freezing next week, with a chance of wintery showers.
Weather forecaster Simon King told Radio5 Live: “We are going to see mild weather over the next week or so and then just in time for Christmas temperatures are going to drop down, so it will turn colder over the Christmas period.
“Temperatures will come below the average. It means for the whole White Christmas thing there will be wintery showers, and while it’s still very uncertain, it will certainly be cold enough over the Christmas period for there to be wintery precipitation.
“There may be snow for some, but for now though it’s really mild, esspecially for this time of year.”
For some, it could spell disaster, with potential disruption on the roads, and temperatures plummeting
Between the 16th and 25th December, the Met Office confirms that the weather will remain unsettled, with a mixture of blustery showers and brighter spells for most of the UK.
Snow has already settled in parts of central Scotland and could fall every day until the 25th, according to WXCHARTS models.
And as much as five inches of snow may fall today, according to the Express, with the same amount expected to fall again in the region on Christmas Day.
The west of Scotland could see 4cm on the big day.
Much of Scotland could experience a white Christmas morning with temperatures set to fall as low as -7C on December 25 in central Scotland, with Fort William predicted to be -3C and Aberdeen -2C.
Nicola Maxey, a Met Office spokesperson told the Express: “As we begin Christmas week, it looks likely to stay unsettled, though it’ll feel a little cooler as northwesterly winds bring temperatures closer to average for this time of year.
“Looking further ahead to Christmas Day itself, whilst it is still too early to say with certainty what weather we can expect, there are some signs of high pressure developing which could bring a colder, drier and more settled spell around Christmas Day.”
The Met Office also warned of powerful winds battering the far south, potentially bringing more cold air between Sunday, December 20 and Tuesday, December 29.
The forecast said: “There is a potential for strong winds in the far south at first; at other times any strong winds are likely to be confined to the north and perhaps the east.
“Prevalence of overnight fog and frost is likely increasing, with fog potentially slow to clear during the daytime.
“Temperatures either close to or slightly below normal.”
