THE Met Office has warned snow showers could spark travel chaos and cut power as an Arctic blast hits the UK.
The mercury has been plummeting to sub-zero this week, with Brits waking up to icy fogs and freezing winds.
Yesterday, Tyndrum in Scotland had the coldest temperature, dipping to a bone-chilling -7C.
And forecasters said they'd expected the Scottish highlands would have likely hit similar temperatures overnight.
Now, the Met Office says the icy weather is looking to stick around, with "disruptive snow" on its way next week.
It's also put two snow and ice warnings in place in coming days.

One of the yellow alerts covers northern Scotland and up to the Shetland Islands from the early hours of Sunday and until 11.59pm on Monday night.
The forecasters have warned: "Some roads and railways affected with longer journey times by road, bus and train services.
"Icy patches on some untreated roads, pavements and cycle paths.
"There is a small chance that power cuts will occur and other services, such as mobile phone coverage, may be affected.

"There is a slight chance of snow-covered roads leading to stranded vehicles and passengers, along with delayed or cancelled rail and air travel.
"Some injuries from slips and falls on icy surfaces."
Then, from 3am until 11.59pm on Monday, Northern Ireland has a similar alert in place.
The Met Office warned: "Some roads and railways likely to be affected with longer journey times by road, bus and train services.
"Probably some icy patches on some untreated roads, pavements and cycle paths.
"Some injuries from slips and falls on icy surfaces."
Deputy Chief Meteorologist David Hayter said: “While the initial snow risk from Sunday onwards is looking most likely to be coastal areas in the north of the UK, including North Sea and Irish Sea coasts, there’s an ongoing likelihood of some disruptive snow through the middle to latter part of next week.
“What we’re keeping an eye on for this disruptive snow is where exactly this milder air from the southwest bumps into the cold air that will be in place over the UK.
"It’s where these airmasses meet that there’s a likelihood of some substantial snow for some places.
"At the moment, models are showing us a variety of options for exactly when and how this situation plays out and it’s something we’ll be able to add more details to in the coming days.”
The icy conditions have seen a yellow cold-health alert extended into next week amid fears the risk of “silent killers” will rise.
All of England will remain under the yellow alert until Friday January 18 as temperatures are set to plunge once more.
It comes after forecasters said there will likely to be coastal snow showers in Yorkshire and Humber from Saturday through until Monday.
They also said wintery showers could hit North West England on Sunday, while Glasgow could see sleep and snow on Monday
Met Office expert Will Lang said: "There will be a resurgence in the really cold weather through the weekend.
"It will spread across the whole of the UK during the early part of next week.
"Initially, this means there will be more in the way of showers around the coasts.

"The showers will turn increasingly to snow for many areas, especially further north."
But much of the UK will stay cool and dry for the rest of the week, with temperatures in the low single figures down south.
