A shift towards a "colder phase" of weather has gripped the UK, with overnight temperatures expected to drop as low as minus 6C in several regions, according to the Met Office.
Meteorologists have warned of a "very cold night" on Friday ahead of a brisk start to the weekend, with overnight lows between minus 4C and minus 6C bringing widespread frost by Saturday morning.
Conditions are set to turn slightly milder but remain unsettled on Saturday, pushing heavy rain and showers in from the west, alongside the potential for snow across north-west Scotland.
