Forecasters are saying an icy beginning to the new year, with snow likely over large parts of the UK. Those celebrating are being urged to dress warmly as bitterly cold temperatures are expected for New Year's Eve.
The Scottish capital's renowned Hogmanay events are planned to proceed, following last year's calling-off. This proceeds amid weather alerts for snow across northern Scotland.
"A cold New Year's Eve evening for those partying, so additional clothing will be needed," said the national forecaster.
Across the UK, the weather is expected to be perfect for fireworks shows, with a lack of precipitation and open skies. Readings are expected to be chilly, making warm wraps vital, said forecasters.
Further north, conditions will be cloudier, but this is not expected to affect visibility for viewing fireworks. "It won't be low cloud, mist or murk, so you should be able to see fireworks, just not stars," commented one forecaster.
As we enter Friday, weather warnings are in place across Northern Ireland and from Wales, across parts of the north-west, the West Midlands and all the way to London and most of the south-east of England.
Going into the new year, it will be "chilly no matter where you are," said forecaster Simon Partridge. Temperatures are expected to drop further as snow and gale-force winds are predicted to batter the north of the country.
About 10cm of snow could accumulate to have settled in some areas by Friday morning, reaching up to 30cm on the most elevated routes and peaks.
Meanwhile, amber cold health alerts are in force for the north-east and north-west of England. These are set to remain in place until noon on 5 January, with readings likely to fall to between 3C and 5C.
Officials explained this indicated the weather was likely to lead to major effects across the NHS and care systems. This involves a likely increase in the number of deaths among those with health conditions or those in the older age groups.
The guidance for all is clear: to see the new year in good health, dressing for the cold is completely key.
