Storm Bella: BBC Weather issue warning for possible floods
Snow showers are set to smash parts of Britain from as early as tonight, with up to 18cm expected to fall in Scotland by 9am on Monday morning, 4cm in north Wales and 2cm in the south of England, according to WXcharts. A bitter cold snap will see temperatures plummet to freezing and below for vast areas of the UK throughout the next fortnight as a deep area of low pressure engulfs the country.
Storm Bella – which has brought 100mph winds and flash flooding – will be replaced by a jet stream of cold air from the Atlantic and Greenland.
The latest weather maps forecast snow showers will begin overnight tonight and become more widespread in the coming days.
By December 30, cold air from the Atlantic will see western areas of the UK hit by snow showers with 13cm landing in the far west of Scotland, 3cm in north Wales and 4cm in the north west.
Temperatures will drop to lows of 0C for central and southern parts of the UK with -2C in the north and -5C in Scotland.
Just 72 hours into the New Year is set to bring a blanket of snow showers across the whole of Britain.
On January 3, up to 22cm of snow is expected to fall in Scotland, 7cm in the north of England, 8cm in Birmingham and even 4cm in London and the south east, according to WXcharts.
The covering of snow will send temperatures spiralling once again with overnight lows of -3C in the south, -3C in the north and -4C in Scotland.
Persistent spells of wintery conditions are forecast to remain for the next 48-72 hours before clearing northwards.
During this period there is set to be widespread freezing fog in the early hours and the threat icy roads.
Heavy snow showers are set to continue into the following week with up to 47cm expected and temperatures falling to -10C overnight in Scotland on January 11.
Snow maps produced by Wxcharts show central and western parts of Scotland turning dark purple.
The cold front will begin tonight as temperatures fall below 0C for the whole of the UK, bringing widespread frost.
According to the BBC long range forecast, the cold and unsettled conditions are being triggered by a weather system from the Atlantic moving southwards to allow Arctic conditions to push in from Iceland and Greenland.
The seven-day forecast warns the cold weather system will head towards Europe before moving in a westerly direction towards the UK.
It says: “This pattern will steer several low pressure areas south over the UK.
“This will allow cold air from Iceland, Greenland and even deeper into the Arctic to flow southwards over the UK, in the wake of these systems.
“A combination of cold and unsettled weather in mid-winter means that sleet and snow will be on the cards for some of us, even over some lower lying areas.

“Fronts pushing south-eastwards are most likely to bring snow to some of the hiller parts of the UK, where a covering of snow will build up during the week.
“At low-levels, it is more likely to be a very fine balance between rain, sleet and snow, with the detail very challenging.”
Netweather.TV forecaster Terry Scholey added: “The now slowly filling storm Bella, continues to move South on Monday, when it may be the turn of parts of England and Wales to wake to a carpet or dusting of snow, particularly in hilly areas.
“But for most, it’ll end up another day of sunny intervals and wintry showers after an icy start.
“Further snowfall is likely, especially on northern hills, but at lower levels the showers may fall as rain, sleet or hail at times.
“It’ll be another cold, raw day in a northerly wind, with top temperatures only 2 to 5C.”
