Britain is bracing for bitterly cold conditions to strike this weekend, with thermometers expected to plunge to as low as -6C in some areas. The Arctic air is barrelling southwards and will grip the entire country by Saturday, forecasters have claimed. Writing on Twitter, WxCharts, which produces weather data, said the bone-chilling air is expected to dominate due to the jet stream.
They wrote on Twitter: “It’s turning much colder towards the end of the week, thanks to the meandering influence of the jet stream.
“The textbook omega block sat to the west of the UK will leave much of Europe stuck beneath a deep upper-level trough, allowing cold air to pour in.”
Met Office spokesman Oli Claydon said the cold temperatures would likely result in snow over the hills of Scotland over the weekend, while the result of the country will be impacted by the “cold and crisp” conditions.
He said: “By Friday morning pretty much all of the UK will be very cold and crisp, apart from the southwest will be milder.

“Low pressure will bring rainfall to the region into the weekend while the rest of the UK remains very cold with widespread frosts.
“We are looking at overnight temperatures of between -6C (21.2F) in Scotland and -2C (28.4F) in London, in Scotland there is a chance showers will fall as snow over the hills at the weekend.
“Although milder air will move into Scotland at the start of next week, the rest of the country will stay cold through Monday and Tuesday.”

The latest weather forecast charts also show the chances of snow falling increase in the far north of Scotland over the weekend.
BBC Weather forecaster Helen Willetts warned about widespread fog causing chaos for Britons towards the start of the weekend.
She said: “We are in for drier weather for the weekend, yes but some very cold nights and the risk of fog.
“It does look as though the frost will be more widespread that last night, because temperatures will be a couple of degrees lower again and frost will be harder as well.

The warning says: “Fog is likely to lead to some travel disruption on Friday night and Saturday morning.”
The Met Office claims the fog could cause “slower journey times on roads” as well as possible “delays or cancellations to flights”.
