Flights to and from Scotland have been cancelled and police have urged motorists across Tayside to drive cautiously after temperatures plummeted to -11C overnight.
A Met Office yellow warning for snow and ice is in place for the region, and neighbouring Grampian, until noon today, and another will be in place from 3pm until 11am on Tuesday.
Tayside is once again expected to dodge the worst of the conditions with no snow forecast for Dundee, however wintry showers will hit the east coast of Scotland overnight.
Flights to and from Edinburgh and Glasgow have been cancelled as a result of the freezing weather, with journeys in and out of Aberdeen International Airport also affected.
British Airways said Heathrow Airport is “continuing to experience severe adverse weather conditions” and reduced its flight schedule for Monday.
