Another cold blast will see temperatures plummet as low as minus 12C overnight this week. 

A snow and ice alert remains in place across Scotland until 11am with snow showers filtering in from the north. 

Southern Scotland will continue to see snow into the afternoon but the bitter conditions will ease across much of the country. 

However, in Shetland further spells of heavy snow will see blizzard conditions in the area. 

It could mean possible travel disruption, particularly for high-sided vehicles.

Delays to road, rail, air and ferry transport are likely along with possible damage to trees across the country on Tuesday morning. 

Residents will have to deal with rain, sleet and snow followed by ice, which is likely to have some impact on travel, according to the forecasters.

Met Office meteorologist Simon Partridge said wintry weather would hit the UK overnight, with lows of minus 11C expected in the sheltered glens of Scotland on Monday, dropping to minus 12C by Wednesday morning.

He said cold air in Scotland on Monday will push across the whole of the UK by Tuesday afternoon.

He added: “Wednesday overnight will be very cold for pretty much the whole of the UK, so if you’ve got plants that have gone out early, get them in tomorrow because the frost is going to be widespread in the morning.”

But the week will be “unsettled”, with the weather shifting to rainy and windy amid milder temperatures from Thursday onwards, he said.

“There’s some cloud and rain on Wednesday onwards pushing back in from the west, so milder air comes in – there will be some snow on the front of that rain but it won’t last very long. Thursday’s main concern is how much rainfall there will be.”

The Met Office said: “Cold air spreading southwards across the UK, following a band of rain, sleet and snow, will bring frequent snow showers to northern, western, and eastern Scotland, as well as parts of Northern Ireland.

“Overnight, these will accumulate on some roads and pavements, with anywhere between a light dusting and several centimetres of snow possible.

“Between the showers, partially melted snow is likely to freeze on untreated surfaces leading to icy stretches.

“Wintry showers will continue through Tuesday, although by mid-morning the temperature on most roads will likely have risen sufficiently to reduce the risk of further accumulating snow or ice.”
