Two yellow weather warnings for snow and ice are in effect from the Met Office, as Britain braces for a bitterly cold Thursday night and buffeting snow on Friday. However, maps and charts see that the weekend will bring a change in weather, with much of the UK soaking throughout.

After Thursday and Friday bring heavy storms in the north, much of Britain will see at least 1cm of snow on the ground by Friday night according to maps from WXCharts.

As midnight sets in however, pressure systems bringing wet weather from Greenland will continue to push across the UK, with rainfall up to 2mm an hour striking the Outer Hebrides and parts of Northern Ireland overnight.

While snowfall is expected to continue in Scotland, by 6am on Saturday the band of weather will see much of the west coast of Britain soak, with Manchester and Liverpool seeing 5mm of rain an hour.

As the morning continues, the worst of the wet weather will have pushed through Scotland, with less than 1mm of light rain falling along the west coast, while the heavier rains push into the midlands, Wales and parts of south west England.

Wales will see the worst of the rain at this time, with 3 to 5mm of rainfall expected.

As Saturday continues, the initial band of rain will have pushed through much of Britain, with London and the south east seeing the end of 3mm downpours by 3pm.

Another band of Atlantic weather, albeit much weaker, is expected to strike at this time, seeing light snowfall along the west Scottish coast and near Derry.

A more settled night, with intermittent rainfall, is predicted as Sunday then sees patches of rain and snow throughout Britain.

By midday on Sunday, Manchester will see the worst of the weather with up to 3mm of rain and 2cm of snow featuring.

Jo Farrow, Netweather.tv forecaster, said “Polar Maritime air from Greenland, moving across the North Atlantic”, is set to pick “up moisture and then throwing a lot of showers our way” by Friday.

She wrote for the website: “Through Friday morning a new little low centre develops off SW Britain, which links back to another Atlantic low pressure off the tip of Greenland and again heading near to Iceland.

“This will move over SW England, the West Country and South Wales later on Friday morning with cloud and rain but also hill snow.

“Worth bearing in mind for Exmoor and Dartmoor with a slight veer in the wind by the afternoon. Temperatures by day will be 3 to 6C and it will feel cold in the wind and damp air.

“The showers ease later in the day as pressure rises. Another frost for Britain early on but milder air will edge in from the west overnight ready for Saturday, away from the far north.“

Two yellow snow and ice warnings have been issued by the Met Office, with western Northern Ireland and a stretch from the Outer Hebrides and northern-most Scotland all the way through to Manchester covered.

Northern Ireland’s weather warning is in effect from 8pm on Thursday to 11am on Friday, while the western band in Britain’s warning starts at 8pm and finishes at midday.

The Met Office said: “Frequent sleet, hail and snow showers may lead to some disruption to travel during Thursday night and Friday morning.”

The forecasters added to expect travel delays with a “chance of some stranded vehicles and passengers, along with delayed or cancelled rail and air travel”, as well as a “small chance that power cuts will occur and other services”.

Speaking to Sky News, Met Office spokesman Grahame Madge warned of the potential for thundersnow.

He said: “Because you have got that differential it’s possible, quite easily, for warm air at ground level when it heats up to start to rise very quickly up through the cold air and that’s what creates the potential for thunderstorms, so we are likely to see along with the other wintery showers, likely to see hail and snow.”

Sky News weather producer Joanna Robinson also said: “Rain will spread across all areas today, bringing snow to higher ground in Scotland, northern England and Wales. Strong winds on the hills will bring the risk of drifting and blizzards too.

“Blustery, wintry showers will follow, with local thunder possible in the west, mainly the Northwest. A thunderstorm that occurs with wintry precipitation is called thundersnow and is quite rare.

“The lightning can appear brighter because of the light reflecting off the snowflakes, but the snow can dampen the sound of thunder.”
