Homes in northern Scotland will be the first battered by freezing temperatures as mercury plummets below the seasonal average, forecasters have warned.
A sudden cold snap will start today, with temperatures falling below zero across the country and peaking at just 4C (39.2F) or 5C (41F), Meteogroup, the weather division of the Press Association, said.
North-westerly winds whipping off the Arctic are expected to bring at least two weeks of near-freezing conditions, making November up to 3C (37.4F) colder than last year.
A Meteogroup forecaster said: "It does look like much of the UK is in for a cold spell through next week. For at least a week, there will be cold north-westerly winds.
