The Met Office has issued a warning for the UK as it braces for a surge of cold Arctic air, bringing sleet, rain, and heavy snow that may lead to significant disruption.
On Thursday and Friday, snowfall could reach 25 cm in areas above 400 meters, 5 cm above 200 meters, and up to 2 cm at lower elevations. Icy conditions are also expected.
Temperatures are set to drop below average for this time of year starting Wednesday, with the entire country experiencing dry, cold Arctic air and an ongoing risk of ice overnight.
Yellow weather warnings have been updated for Northern Ireland, northern England, parts of the East Midlands, and north and central Wales, covering 6 am Thursday to 6 am Friday.
Up to 25 cm of snow is expected in high areas, causing potential travel disruptions.A separate warning for snow and ice in northern and western Scotland will be in effect from 3 pm Tuesday until noon Wednesday, with up to 8 cm of snow possible in the north-west Highlands.
These warnings follow a notably mild period that saw early blooms of snowdrops and daffodils. This winter has been unusually stormy, with 10 named storms by January, surpassing previous years since the Met Office began naming them in 2015.
The coming week will see a clash of air masses, bringing rain, sleet, and snow. The heaviest snow is expected where the cold and mild air meet. There is a small risk of power outages, mobile coverage disruption, and travel issues, with some rural areas potentially cut off. Snow is expected to ease later on Thursday, possibly turning to rain or drizzle.
Chris Almond, deputy chief meteorologist at the Met Office, highlighted the increased risk of wintry hazards as cold air moves over the UK.
The initial snow risk is highest in northern England and Wales. The UK Health Security Agency has issued a yellow cold weather alert for parts of England, advising extra care for the elderly and vulnerable.
Amy Shaw from National Highways stressed the importance of planning journeys, checking weather forecasts, and driving cautiously in adverse conditions.
