Wintry showers were forecast across the far north of the UK overnight, according to the weather forecasting channel MetDesk. They also warned there was “no sign of any significant mild weather for at least another week”, with the bitter temperatures expected to continue to grip Britain. Freezing air from the Arctic is on course to send temperatures falling to lows -7C on Sunday night.

Precipitation maps produced by WXcharts show a band of rain and isolated snow showers closing in later today.

The cold-weather system is currently moving in a southwesterly direction and is on course to bring snow and ice to northern areas.

The band wet and wintry weather is poised to push further south and bring more unsettled and cold conditions over the weekend.

In a post on Twitter yesterday, the MetDesk wrote: “The northerly winds returning!

“After a couple of days of less cold air, a renewed plunge of Arctic air follows a southward-moving cold front to end this week.

“Snow showers reaching the far north tonight and no sign of any significant mild weather for at least another week.”

The Met Office has put in force a yellow snow and ice warning for parts of the UK.

The alert covers the far northwest of Scotland and will remain in place until at least 10am.

It says: “Snow showers will start to affect parts of northern Scotland during Thursday afternoon and evening and will become heavier and more frequent overnight.

“Accumulations of snow will be small and patchy at lower levels, and not as widespread as earlier this week, however, the additional hazard of patchy ice is expected form on some surfaces between showers.”

Scotland could accumulate up to 8cm of snow in northern areas by 9am on Friday morning, according to snow depth maps.

WXcharts predict western parts could also see a fluttering of wintry showers with between 1cm-7cm forecast.

Temperatures are expected to fall to with lows of -6C in central areas of Scotland by 6am on Friday.

Mercury will remain below freezing for northern areas of England with lows of -2C, temperatures in central and southern parts will remain in small digits, with lows of 2C and 3C, respectively.

Freezing Arctic air will become more widespread over the whole of the UK into Saturday evening and overnight on Sunday.

Temperature maps show the whole of Britain turning ice-blue with thermometers falling to -7C in central Scotland by 3am on Sunday.

Mercury is forecast to drop to bone-chilling lows of -4C in the northern areas of England and in Wales.

The Midlands is on course to feel temperatures of -2C and 0C in the south of England.

A strong Arctic breeze could see temperatures feel even colder as wind-chill maps show the whole of Britain turning purple.

The chilling forecast by WXcharts suggests temperatures could feel closer to -10C in some parts.

Later today, the Arctic blast will bring the threat of sleet and snow, but will also result in brighter skies.

NetWeather.TV forecaster Paul Michaelwaite said: “Further north, though, there’ll be sunnier skies thanks to the return of Arctic sourced air.

“There’ll be some showers around though, particularly across Scotland, and with cold air in situ, many of those will be of sleet, snow or soft-hail.”

He added: “Overnight, some showers will continue in the north and west, but with often clear skies, there’ll be a widespread and, in places, hard frost from the Midlands northwards.

“Cloud with patchy rain, sleet and snow will continue to affect southern and perhaps central England.

“That threat will continue into Saturday, as low pressure moves nearby from the Atlantic and into France, although there’s a lot of uncertainty over this.”
