The North-east is braced for more wintry weather with temperatures expected to plunge as low as -10C at the weekend.
Forecasters are predicting a cold spell following snow and sleet earlier in the week.
Motorists faced difficult driving conditions as snow fell across some parts of Scotland last night and police issued a warning to drivers travelling the north of the country after 6pm.
They warned people in Aberdeen City and Shire, Moray, Angus, the Western Isles, Highlands and Perth and Kinross that there was the likelihood of snow and ice on the roads.
Cold temperatures are expected to continue over the next few days and will widely drop below freezing overnight and could be as low as minus 5C in parts of Scotland with lying snow.
On Friday night the mercury could fall as low as minus 8C over parts of Scotland and could plunge to minus 10C on Sunday night.
Alex Burkill, a Met Office meteorologist, said: “On Sunday night into Monday temperatures could get as low as minus 10C or a little bit below in parts of Scotland, with lying snow and to minus 3C or minus 4C across many parts of the UK.
“It will be a cold frosty start on Monday with a harsh frost.”
He said more snow could be expected across the hills in Scotland and northern England on Saturday, and there was the chance of sleet in London.
However, forecasters said it is unlikely to be the coldest night of the year so far, which was overnight from January 20 to 21 when the mercury dropped to minus 13.7C at both Altnaharra and Kinbrace in the Highlands.
Bookmaker Coral is odds-on at 10-11 for the temperature to drop to as low as -15C by the end of the week in the UK.
The firm said it continues to see a flurry of bets for February to be the coldest on record, where it is 6-4 in the latest betting, while it is 2-1 for snow to fall in London by the end of the weekend.
