Forecaster Phil Morrish told Express.co.uk the weather will turn colder throughout the week, with snow and “winter” showers hitting the country due to “arctic air”. Weather forecaster WXCharts predicted snowfall across the UK, with maximum snow depth reaching 6cm in Scotland on Thursday. Manchester can expect to see up to 3cm of snow, with up to 2cm in Newcastle.
It also forecast lows of -8C in Scotland and -5C in Newcastle on Thursday.
London and the South East can expect temperatures between 0 and 3C.
Speaking to Express.co.uk, Mr Morrish predicted a major change in conditions from the mild temperatures seen in the UK last week.
He warned that the weather will be “much more like winter than spring”.
However, the forecaster said freezing temperatures will only last for up to three days, before turning milder again.
He told Express.co.uk: “We have a large area of high pressure sitting across the country.
“Last week it sat in the east of the country giving us warm, Saharan air, but this week it is now moving northwest.
“What it’s going to do is gradually bring down very cold arctic air, which is currently at the north pole.

“Going down about 100m to settle, but even further south there will be wintry showers on Thursday and Friday as this cold arctic air sinks in from the North Pole.
“It lasts two or three days and then it will gradually become a little less cold.”
He added: “After a very mild week, it will become much cooler this week and there will be overnight frost as well.
“So temperatures drop below zero once you get to Wednesday, Thursday and Friday in the Glenns of Scotland, maybe -5C.
“So it might have looked like spring last week, but this week will be very different as the high pressure moves to different places, bringing much colder air for us this week.
“So it will look a lot more like winter than spring.
“But it’s British weather for you, especially in April.”
