Yellow weather warnings for ice and snow are to remain in place until Tuesday afternoon amid freezing conditions for parts of the country.
The alert is set until 3pm for the North and East of the country, with travel disruption possible as far South as Perth.
Wind and rain in the west will move east as Tuesday morning progresses, falling as snow over parts of the country.
Elsewhere, other warnings covering ice in Edinburgh and Glasgow are expected to remain active until 10am.
The snow is forecast to fall in higher parts of Scotland, with some places seeing up to 10cm.
The Met Office said: “Accumulating snow will be focused across Highland and Grampian overnight with a further 1-4 cm likely in places above around 150 metres, although patchy snow could accumulate at low levels, especially in the far north.”
Traffic Scotland has confirmed that gritters are out on the road and that ice and snow is already on several major roads, especially on the A82 and A87 in Invergarry, and has asked people to “plan ahead”.
Routes on the Scottish Borders have also been affected by black ice and snow on the A68 at Carter Bar and the A7 around Selkirk and Mosspaul.
