A major Arctic weather event, reminiscent of the infamous 2022 snowstorm, is set to strike the United Kingdom as the new year begins. The so-called 'Troll of Trondheim' is forecast to make a dramatic return, driving a colossal wall of snow straight from Scandinavia across the North Sea.
An Arctic Onslaught: The Mechanics of the Storm
Senior meteorologist Jim Dale from British Weather Services explains that the severe conditions are triggered by a dislocation of the polar vortex. This spinning band of low pressure around the Arctic is being disrupted by stratospheric warming, pushing frigid air southwards. "It is an Arctic push right across Scandinavia," stated Mr Dale. "Remember the Troll from Trondheim? It looks like it could well be a replay of that."
This meteorological phenomenon will not only affect the UK but also much of northern and central Europe. The initial impact will see a giant wall of snow, stretching approximately 540 miles from Amsterdam to northern Scotland, moving across the North Sea. Forecasts indicate the peak of this wall will be visible on Friday morning.
Forecast Timeline and Expected Snowfall
The Met Office has issued a yellow weather warning for snow and ice for northern Scotland, effective from 6am on New Year's Day until the end of Friday, 2nd January. Deputy chief forecaster Mark Sidaway confirmed the widespread nature of the incoming cold spell, stating it will bring "the first snow of the winter for many."
According to detailed forecasts:
- New Year's Eve and Day: Snow will begin affecting Scotland, with up to five inches (12-13cm) expected in northern regions like the Highlands and Grampians.
- By January 4: The snow is predicted to push further south, reaching Norfolk and central Wales.
- Through the first week: The cold spell is expected to persist, with snow potentially reaching areas like Dartmoor, the spine of Wales, and even Dorset. Weather maps suggest some parts of Scotland could see accumulations of up to 33cm by January 7.
Jim Dale noted that after Scotland, the North East of England is likely to be hit hardest, before the system integrates southwards.
Preparing for a Prolonged Cold Snap
The return of the Troll of Trondheim evokes memories of its last significant impact at the end of 2022, which brought nearly five inches of snow to Scotland, temperatures plunging to -7°C, and widespread warnings for ice and freezing fog.
Authorities are urging the public to prepare for a sustained period of wintry conditions. "It certainly looks like we are in for a taste of ‘winter’ as we welcome in the New Year," warned Mark Sidaway from the Met Office. He emphasised that Arctic air and strong northerly winds will bring cold or very cold conditions to all parts of the UK, with severe frosts and disruptive snow. The public is advised to keep updated with the latest forecasts and official warnings as the situation develops over the coming days.
