Scots have been warned to brace for what could be the coldest night of the winter so far, with temperatures plunging to -10C (14F) or below tomorrow night.
Today sees a dramatic move away from the quiet conditions much of the country has experienced this week.
Later today the Met Office is expected to issue a warning for snow and ice tomorrow morning, when lows of -5C (23F) could make things difficult for drivers and pedestrians.
But, after a chilly day, the mercury will fall even further through the night, with -10C (14F) predicted by the Met Office for Tuesday morning.
Forecaster Simon Partridge said: “Monday night is shaping up as the coldest night of the winter so far.
“We did see a low of -10.3C in Scotland in November, so it’s possible that record could fall this week.
“At the same time, snow could come down to lower levels – even in the central belt – but it is not going to last too long.
“After Tuesday, it’s all change again as things turn milder on Wednesday.”
Rain, which began to cross Scotland last night, is expected to clear the country by this afternoon.
Ferry services may also be cancelled due to high winds.
