Heavy snowfall is expected in the UK on Tuesday after the Met Office issued a weather warning for the white stuff.
Forecasters say the worst affected areas will include northern England and parts of Scotland, with potentially four inches of snow on the way.
Gusts of up to 70mph are set to hammer Britain and Northern Ireland as Storm Barra makes landfall.
A Met Office wind warning has been issued for the majority of the country on Tuesday.
Rainfall may turn wintry in the early hours of Monday morning in western parts, including the Welsh hills.
Here's what to expect in the coming days.
Monday
This band of rain from the Atlantic, moving into extremely cold air in the UK currently, reaches Wales at around 4am - and if cold enough - will fall as snow.
"Some snow is likely over higher parts of Scotland, perhaps briefly in the Pennines," BBC forecaster Darren Bett says.
It'll be frosty for most of Monday morning elsewhere and particularly wet where the precipitation does fall as rain.
Flooding warnings have been issued for the Cumbrian coastline on Monday afternoon.
Large waves are expected to crash into the shore near Morecambe, Lancashire, as the Environment Agency warned of potentially dangerous weather.
Temperatures are expected to drop to freezing in central Scotland overnight, according to the Met Office.
Tuesday
A deepening area of low pressure moves quickly in from the west as Storm Barra makes landfall in the UK on Tuesday.
The Met Office has issued the weather warnings as a result of this, with the snow alert in force from 11am until midnight.
Up to 10cm of snow is expected to fall across parts of the UK on Tuesday morning.
Southern Uplands and Highlands will be worst affected by the fresh snowfall at this stage.
But North Yorkshire, West Yorkshire, Cumbria, Lancashire, Greater Manchester, Derbyshire and Durham are all subject to the weather warning, among a host of other places.
Eastern places, like Durham and Northumberland, will see most snowfall later in the afternoon and evening, it is believed.
A wind warning is also in place across all of Northern Ireland, Wales, England and parts of Scotland on Tuesday.
The alert is in force from 9am until midnight, with warnings of gusts of up to 70mph in coastal areas.
Wednesday
The winds will have weakened by Wednesday, although gusts of around 50mph are still possible in coastal areas, according to the Met Office.
Parts of north Wales and the Midlands might see flurries of snow in the early hours of the morning.
This will fall as more rain in urban areas, including Birmingham and Cardiff.
The winds will be at their strongest in coastal locations, particularly in the west and southwest.
A Met Office spokesman said: "A deep area of low pressure moving in across the UK from the Atlantic is likely to bring high winds to many parts of the UK. Strong winds arriving into the west through the morning, spreading inland and reaching eastern areas through the afternoon and early evening.
"Gusts of 45-50 mph are expected widely, with 60-70 mph in exposed coastal locations. Strongest winds will ease across inland areas into the overnight period."
Thursday and Friday
Guests will die down on Thursday although temperatures will remain cold.
Rainfall will start to ease across the country and be replaced by overcast weather.
Things will turn even chillier on Thursday evening, with a freezing night on the cards for much of Scotland.
A few showers are possible in south-west England on Friday morning, although there could be some sunny spells throughout the country in the afternoon.
