The Met Office has issued yellow weather warnings for the inclement conditions. The warnings advise “icy stretches will be the main hazard on Sunday morning”. They mean there is an increased likelihood of accidents and injuries due to slippery surfaces.
The warnings cover Central, Tayside & Fife, east of England, Grampian Highlands & Eilean Siar, London & south-east England, north-east England, north-west England, south-west Scotland, Lothian Borders, south-west England and Strathclyde.
They come after adverse weather conditions caused widespread travel disruption towards the end of the working week and into the start of the weekend.
Commenting on the conditions, Met Office meteorologist Ellie Creed said: “There will be plenty of clear spells and unsurprisingly temperatures will take a tumble.”
The mercury is set to plummet “quite widely” into negative digits on Sunday morning as cold air bites.
However “out in the countryside” it is going to be “even colder”, with some parts of the south-west seeing temperatures as low as -8 degrees Celsius and sheltered glens in Scotland getting as low as -13.
Ms Creed said: “Further north, the likes of Braemar, -12 even -13 degrees Celsius possible.
“So a pretty chilly start a crisp start for many into Sunday.”
There will still be some sunshine around, particularly for the north of England, the weather expert said.
She added: “But the cloud erodes away that fine weather slowly but surely through the day.”
A band of snow, sleet and hill fog will “gradually turn and start to pivot across parts of northern England later on in the day”, the Met Office forecaster warned.
She said: “By this point largely rain.
“To the south of it largely dry with some sunshine still.
“To the north feeling colder but wintry showers around as well.”
