Weather experts have indicated a frosty commencement to the new year, with snowfall expected over large parts of the UK. Celebrants are advised to wrap up as sub-zero temperatures are forecast for New Year's Eve.
Edinburgh's iconic Hogmanay events are set to proceed, following last year's cancellation. This comes despite yellow warnings for snow across northern Scotland.
"A chilly New Year's Eve night for those out celebrating, so warmer clothes will be essential," stated the Met Office.
Across the UK, the weather is set to be suited to fireworks shows, with no rain and good visibility. The mercury are due to be cold, meaning extra layers vital, said forecasters.
To the north, conditions will be cloudier, but this is not anticipated to hamper visibility for watching fireworks. "There is no expectation of low cloud, mist or murk, so you should be able to see fireworks, just not stars," added one forecaster.
Heading into Friday, advisories are active across Northern Ireland and stretching from Wales, across parts of the north-west, the West Midlands and reaching London and most of the south-east of England.
Going into the new year, it will be "chilly no matter where you are," stated forecaster Simon Partridge. Conditions are forecast to drop further as snow and gale-force winds are likely to batter the north of the country.
About 10cm of snow could accumulate to have built up in some areas by Friday morning, with up to 30cm on the top roads and uplands.
Meanwhile, serious cold weather health warnings are in force for the north-east and north-west of England. These are due to remain in place until noon on 5 January, with the mercury likely to fall to between 3C and 5C.
The health agency explained this indicated the weather was likely to cause major effects across health and social care services. This involves a likely increase in the fatality numbers among those with health conditions or those aged 65 or over.
The message for all is clear: to see the new year in security, dressing for the cold is absolutely key.
