The Met Office has said roads and railways are likely to be affected, with the fresh warnings in place until 11am on Friday and covering parts of Scotland, the North East, as well as Yorkshire and Humber.

They have now been updated to include most of eastern England, the South West and the East Midlands.

Snow has already fallen in parts of northeast England and there were reports of road closures and a stranded bus in Yorkshire on Wednesday.

It comes amid a blast of cold air from northern Scandinavia, resulting in a cold snap for many.

The Met Office said the three lowest temperatures recorded at its observation sites overnight were all in Cumbria, with a low of -7.2C in Bridgefoot, -6.5C in Shap and -6.1C in Keswick.

Daytime temperatures are expected to plunge to single-digit figures this week, and it is expected to stay below freezing for large parts of England and Scotland through the night.

People living in the affected areas have been advised to expect showers that will likely see ice form on untreated surfaces, which may make some roads and pathways hazardous and slippery.

The Met Office said: "Showers, wintry in places, will continue to affect northern and eastern Scotland and eastern England through Thursday evening and overnight into Friday morning.

"These are likely to fall on to frozen surfaces allowing icy patches to form.

"From approximately the Humber northwards, showers will often fall as snow inland, with up to 2cm possible in places, and perhaps as much as 5cm over high ground. Further south, any snow accumulations are more likely to be restricted to higher ground."

The Met Eireann has issued a yellow fog warning for large parts of the Republic of Ireland.

The Met Office added: "Spells of snow may develop over hills, especially parts of Bodmin Moor, Dartmoor, Blackdown Hills and Exmoor during the early hours of Thursday before petering out later in the day.

"The highest parts of Dartmoor and perhaps Bodmin Moor may see 5-10cm of snow with some drifting in strong easterly winds.

"Elsewhere, accumulations are likely to be relatively small, perhaps 1-3cm at most, and mainly in areas inland and above 100-200m. In addition to this, icy patches may also develop on untreated surfaces."

Tips to keeping warm this winter

North Yorkshire Police on Wednesday warned motorists of road closures "because of snow and ice".

The A169 was closed at White Way Heads/Saltergate Moor, the force said earlier, urging drivers travelling between Pickering and Whitby to use an alternative route.

North Yorkshire Council said gritters and ploughs had been sent to the scene to clear the road.

"A169 Blue Bank looking slippy again after another large snow shower passed through," a social media user posted on X, formerly Twitter, at around midday.

Coatham Coaches said staff had been out early between Guisborough and Whitby and the main moor road "is passable", but warned people to take care.

"Only snow seems to be on higher ground but we'll assess all routes the best we can as our school/college coaches start their day."
