The UK is in the grip of an unusually cold snap, with freezing winds and snow flurries sweeping across the nation.
Strong gusts of up to 50mph mean that temperatures hovering around freezing point could feel more like -10C (14F) in some areas.
The temperatures are much colder than normal for this time of year, when we should expect averages of around 6-8C (43-46.4F).
Temperatures plunged as low as - 9.7C (14F) in northern Scotland overnight, and the mercury struggled to beat zero around the country.
The lowest reading was at Altnaharra in Sutherland, but there were many others approaching that in northern Scotland.
The cold winds bringing sleet and snow have been coming in from the North Sea.
Temperatures in the capital are set to plunge to -2C (28.4F) later tonight, with the wind chill making it feel even colder.
Further dustings of snow are forecast in eastern and central England on Friday, as the half-term holiday nears its end.
Up to a couple of centimetres are due over the southern Pennines, the hills of Yorkshire and some parts of Kent overnight.
The cold spell is set to continue over the weekend due to raw easterly winds.
On Saturday there is an increasing risk of snow flurries coming in from the east and spreading across the west towards Wales leaving a dusting of snow behind.
It will remain cold on Sunday with more wintry showers before temperatures start to rise on Monday.
Temperatures are expected to reach as high as 7C or 8C in the south by the end of the week.
More cold winds could come in from the northwest around that time, though there is no sign of a return to the significant snowfall seen earlier this winter, or of a sustained mild spell.
