BBC Weather WatchersFresh weather warnings have been issued by the Met Office for further snow across Scotland on Sunday and Monday.
Weather presenter Kirsty McCabe, editor of MetMatters at the Royal Meteorological Society, said there could be up to 20cm of snowfall in places.
She told BBC Radio’s Good Morning Scotland programme: “There’s potentially a lot of snow to come, but as well as the snow there always the risk of freezing rain.
“You can get black ice, really hazardous conditions on the roads.
“It’s not especially unusual, its not record-breakingly cold, but it’s not great as Monday for many is going to be the first day back at school or back at work.
“There will be this legacy of wintry weather and nasty conditions.”
The yellow weather warning for snow is in place from the early hours of Sunday until midday on Monday.
The Met Office said the greatest risk was in southern and eastern Scotland, where up to 5cm could accumulate, with 10 to 20cm over high ground.
Rain or sleet is more likely near some northern and eastern coasts.
