Forecasters have warned of dangerous conditions on the road and more air travel disruption on Thursday as winter tightens its grip on the UK.
The Met Office has issued yellow warnings of ice for large parts of England, Wales, Scotland and Northern Ireland after snow brought major disruption and power outages to swathes of the UK on Wednesday.
Hundreds of passengers were stranded at Stansted airport yesterday and fliers may experience fresh delays because planes will need de-icing, with London Luton urging passengers to check with their airlines before travelling.
Stansted said all flights were anticipated to operate as scheduled on Thursday, although passengers were reminded to check their flight's status before travelling to the airport.
The Met Office said temperatures fell to as low as -4.5C in Katesbridge, Co Down, in the early hours of Thursday while most parts of the UK hovered around 0C.
Two yellow warnings for ice covering parts of the country are in place until 11am, with road users being warned of treacherous conditions on untreated surfaces.
Sub-zero temperatures are expected widely across the UK again on Thursday night, with the mercury expected to plunge as low as minus 10C (12F) in parts of Scotland and Wales.
A yellow warning of snow has been issued for the East Midlands, the north of England down to the Humber and southern Scotland from 3am on Friday until midday.
A band of occasionally heavy rain is due to move eastwards across the UK that will turn to snow as it meets cold air, with up to 5cm expected.
