Britain is braced for a cold snap as Arctic conditions sweep in from the North bringing snow, ice and freezing temperatures.
Snow has already hit parts of Scotland and the north of England and the Met Office has issued warnings for the rest of the UK this week.
We take a look at what the forecasters are saying is likely to happen for the rest of this week and who can expect to be seeing some snow.
Is it going to snow today?
The Met Office forecast for Tuesday is for a “band of rain and sleet, with perhaps a little snow in places”.
This will slowly clear from southern England. Elsewhere there will be sunny spells but also snow and hail showers, these will be frequent and heavy across northern Scotland.
It is expected to feel cold for all.
Yellow weather warnings for snow and ice were issued by the Met Office for Tuesday, one was in place across London, the South East, the Midlands and much of Wales until 10am this morning.
A second covers the north and east of Scotland and north east England from midnight today until 10am on Wednesday.
Parts of Scotland, the north of England and on higher ground in The Midlands and South East England have already had some snow with schools in Shetland, Aberdeenshire and the Highlands closed.
More than 10cm of snow fell in parts of northern Scotland on Monday and 20cm of snow could fall later in the week.
What’s the forecast for the UK?
The outlook for the whole of the UK is summed up by the Met Office as “cold and wintry”.
Tuesday’s “band of rain and sleet, with perhaps a little snow in places” is clearing from southern England but snow and hail is still on the cards further north, particularly heavy in northern Scotland.
Overnight temperatures are forecast to plunge to minus 15C in some isolated Scottish glens.
From Tuesday night to Wednesday, there is predicted to be a widespread frost, with snow and sleet in the South and snow and hail showers on northern coasts.
On Wednesday, meteorologists say there is likely to be further sleet and snow across southern England and south Wales, mostly sunny elsewhere but with scattered snow and hail showers along northern coasts of Scotland.
Then on Thursday it will be generally dry and cold in the north but widespread snow, rain and strong winds will spread north east.
By Friday this is set to clear with any further rain and snow gradually moving north on Saturday.
Where has the Met Office said to expect snow this week?
The Met Office has updated its snow and ice yellow weather warnings for Wednesday with the whole of southern England, the South East, London and South Wales now included in this is from midnight on Wednesday until 9am on Thursday.
Met Office meteorologist Alex Burkill said people should “expect to wake up to snow” on Wednesday if they live in the South.
He said: “I think over higher grounds such as Exmoor, the Chilterns and the Cotswolds there will be a fair amount of snow.
“Elsewhere it is going to be quite difficult, especially after today’s wet weather, to say how much snow will settle.”
Further north, yellow weather warnings are in place for heavy snow which has potential to cause significant disruption on Thursday and Friday.
The areas forecast to be affected are Northern Ireland, North Wales, most parts of Scotland aside from the far north and the north of England stretching as far south as Birmingham.
This warning starts at 3am on Thursday and lasts until 6pm on Friday.
According to the Met Office, there is a chance of long delays and cancellations to bus, rail and air travel, roads being blocked and some disruption to power and water supplies.
The UK Health Security Agency has issued a level 3 cold weather alert for all regions of England in place from1am on 6 March until midnight on 9 March.
