Will the UK be hit by 25cm of snow? Amber Warning Issued as Arctic blast brings dangerous cold snap

The UK is heading into its first significant blast of winter as forecasters warn that temperatures will plunge and snowfall could reach up to 25cm in some regions this week. The Met Office has issued a series of weather warnings, including an amber alert for parts of Yorkshire, as cold Arctic air sweeps across the country.

Following early snowfall in sections of Scotland, much of the UK is now preparing for several days of disruptive wintry weather. The Met Office says this week will feel “markedly colder” than last week, with harsh frosts, bitter winds, and prolonged spells of snow and ice expected.

Amber Warning in Yorkshire

Areas including York, Scarborough, the North York Moors, and the Yorkshire Wolds are under an amber warning from 5am to 9pm on Thursday. Forecasters warn that widespread travel disruption is likely, and some districts could face power outages due to heavy snow and strong winds.

According to Met Office Chief Forecaster Neil Armstrong, the UK is now firmly under the influence of “cold Arctic air,” creating the first notable cold snap of the season. Wintry showers will be most frequent in Northern Ireland, southwest Wales, southwest England, northeast England, and across Northern and Highland Scotland.

While not all areas will see settling snow, those that do could see 2–5cm build up quickly. Higher elevations in Scotland may receive 15–20cm, while the North York Moors could see totals nearing 25cm.

Widespread Yellow Warnings in Force

Seven yellow warnings are in effect on Wednesday alone, stretching across Northern Ireland, Wales, southwestern England, northern England, and much of Scotland. On Thursday, five yellow warnings continue across northern Scotland, the east coast, and the southwest.

Deputy Chief Forecaster Tom Crabtree says the mid-week period carries the highest risk of severe weather, with temperatures potentially dropping as low as -10°C overnight and wind chill making it feel even colder. Rural Scotland could dip below -11°C by Thursday night.

Roads may become dangerous as ice forms quickly under clear skies. Drivers have been urged to take precautions, with National Highways deploying a fleet of over 530 gritters across major routes. Motorists have been asked to check their lights, tyres, and pack emergency items such as warm clothing, food, and torches.

Transport Disruption Expected

Snow and ice have already caused hazardous road conditions in northern England and Scotland. Traffic Scotland warns that frequent snow showers could create sudden delays, while ferry operator CalMac has cancelled a number of services due to “adverse weather.”

Bus and rail services are also at risk of disruption. Travellers have been urged to check timetables in advance and allow extra time for journeys.

Cold Health Alerts in Place

Alongside the weather warnings, the UK Health Security Agency (UKHSA) has issued both yellow and amber cold-health alerts, particularly highlighting risks for older people, young children, and individuals with respiratory conditions.

Dr. Ron Cook of NHS 24 stresses the importance of staying warm and taking care outdoors, especially for vulnerable groups. Cold air can worsen symptoms for those with asthma or COPD, so keeping medication close and limiting time outside during peak cold spells is advised.

Slight Warm-Up by the Weekend

Although the mid-week period brings the harshest weather, conditions may ease slightly by Friday. Much of the country should see drier spells, with rain moving in from the west. The weekend is expected to be milder but wetter, with fronts pushing across the UK on Saturday and Sunday.
