Fresh snow is expected to hit Scotland with forecasters anticipating as much as 15cm to fall over a 24-hour period.
The Met Office has issued a new yellow weather warning for western Scotland to come into force from midnight tonight.
Wintry conditions are expected in Northern Ireland before being pushed east across the Irish Sea.
Experts say that there is a chance of heavy snow to land in large parts of the west of Scotland, with high winds causing blizzard conditions over the hills.
Stirling, the Highlands, Dumfries and Galloway, Ayrshire and Glasgow are among the place to potentially see the worst of the conditions.
The weather warning will remain in place until 11.59pm on Saturday evening.
A forecast from the Met Office reads: “A band of snow is likely to arrive into Northern Ireland during the early hours of Saturday with snow continuing here though the day.
“1-4cm of snow is possible widely with 5-10cm, perhaps up to 15cm over high ground.
“Later snow may turn to freezing rain across parts of Northern Ireland bringing an additional ice risk.
“Whilst there remain a chance of heavy snow for parts of Wales and western Scotland, it is more uncertainly whether there will be sufficient snow to cause any disruption for those areas.
“Strong southeasterly winds across the warning area may lead to drifting and blizzard conditions over hills.”
A further 24-hour snow warning has also been issued for the north east of Scotland, with parts of Angus and Aberdeenshire expected to see up to 10cm of snow to fall from midday today.
The new alerts from the Met Office are the latest in a string of weather warnings issued across Scotland during the first weeks of 2021.
Several inches of snow hit the majority of the Scotland earlier this week, causing disruption to those on essential journeys.
Temperatures also plummeted to extreme lows on Thursday, with the thermostat dropping to lows of -22C in the morning.
A band of milder air is expected to spread across the UK later in the week.
