While parts of the UK have seen fairly mild temperatures this week, a brutal cold snap is due to settle in. Some areas could see temperatures as low as -3C, while snow is forecast widely over the coming week.
While Saturday will remain fairly settled, the real change will come later on Sunday evening.
The Met Office is forecasting conditions to turn colder, with wintry showers in the northwest.
From Monday to Wednesday, things will turn more extreme.
The Met Office forecasts: “Sunny spells and showers, the showers a wintry mix of rain, hail and snow. Snow mostly over high ground in the north.”
And according to Netweather, even London and the southeast could see a dusting on Tuesday, with a 45 percent chance of snow.
Some sites are showing this cold trend continuing into early February.
WXCharts shows some major snowfall across southern parts including southwest England and Wales.
These icy conditions will be preceded by the sudden drop in temperatures, according to the Met Office.
Met Office spokesman Mark Wilson told the Mail Online: “Showers could start to turn wintry across the north on Sunday as colder Polar maritime air enters the UK.
“There is a chance we could see much more developed feature that will bring the risk of severe gales and wintry conditions to the north of the country.
“This would bring some significant snow to the hills and the risk of wintry showers to low ground.”
And Jo Farrow, a forecaster at Netweather.tv, said: “The main low pressure governing this change is already heading towards Iceland today.
“Various low centres develop near to Iceland and southern Greenland, throwing frontal rain and colder air down over the UK on Sunday.
“A secondary low develops during Monday heading out into the North Sea for the start of Tuesday and this has had some interest.
“Next week really will be quite different; windy, unsettled, rain or hill snow on showers whizzing in from the west.
“Much more mobile than the current settled, steady and often grey conditions.”
