On 25 December, Scotland and Northern Ireland can expect spells of rain but the rest of the UK is predicted to stay dry.
Weather’s Louise Lear said Boxing Day will “almost be a case of spot the difference”.
The first signs of a change will arrive late on Friday, Lear said, as north-westerly winds introduce colder air across Scotland.
But those chasing the dream of a white Christmas will have to look to Europe this year.
Fresh snowfall is expected in northern Scandinavia, the Apennine Mountains in central Italy and parts of the Balkans.
