UK weather - live updates: Met Office extends heavy snow warnings as band of rain and sleet moves eastwards across Britain
Latest updates as big chill takes hold
Bitterly cold temperatures hit Britain and a blanket of snow swept across the country on Tuesday, causing schools to close and widespread travel disruption.
The Met Office put severe weather warnings for snow and ice across most of the UK into Wednesday morning. Meteorologists also extended snow and ice warnings to cover Thursday and Friday.
Many parts of the country, including northern England, Scotland and the South West, woke to thick snow and icy conditions on Tuesday morning.
It forced the Highland Council to close 13 primary schools and nurseries, while pupils in north Wales were also told to stay home.
A motorist in the Highlands was stopped by police and handed a fixed penalty notice in the early hours after they were caught driving a snow-covered car with just a small square of windscreen cleared.
Police in Cumbria also urged motorists to slow down after tweeting an image of an overturned car lying on its roof on the M6.
Forecasters warned that Britain is facing “very significant snowfall” for the rest of this week, with temperatures plummet to at least -10C in parts of Scotland on Tuesday night, while a “bitingly cold” Wednesday is set to reach highs of 2C or 3C in some places.

Hello and welcome to The Independent's coverage of today's weather, as the heaviest snowfall seen so far this winter is forecast.
You join us as the Met Office warns up to 10cm of snow could fall on higher ground this week as temperatures drop across large parts of the UK.
Weather warnings for snow and ice have been issued and flurries reported in Glasgow overnight.
Around 0.4in to 1.2in (1cm-3cm) could accumulate on lower-lying levels, with the possibility of 2in to 4in (5cm-10cm) falling on higher ground, Marco Petagna of the Met Office said.
Four separate yellow weather warnings have been issued that cover most of the UK. Mr Petagna said London could see snow showers - but added they were unlikely to settle.
Temperatures fell as low as -7C in the Scottish Highlands overnight, while the capital was at just about freezing as large parts of the country woke up to frost.
During Tuesday morning, a band of rain is set to push from west to east that could fall as rain, sleet or snow, particularly at peaks in Wales and northern England and Scotland.
As the day progresses the wintry weather will move across the Midlands and into the south east.
Snow showers could return on Wednesday and there is a risk of further disruptive snow and ice to parts of the country towards the end of the week.
The weather warning for Northern Ireland - running from 5.30am until 10.30am on Tuesday - said ice may form causing potential problems on untreated roads.
The remaining three are for snow and ice, covering the western side of Scotland and into north west England until 12pm; central regions, Wales and the north east between 12pm and 11am on Wednesday, and the south east, East Anglia and London from 9pm on Tuesday until 12pm on Wednesday
