Temperatures are set to plummet to -10°C across Britain as an Arctic air mass triggers nationwide snow and ice warnings from the Met Office, bringing the first major cold snap of winter.
Yellow warnings for snow and ice cover northern England, the Midlands, and parts of the South East, with temperatures struggling to rise above freezing. Overnight lows of -5°C to -8°C are forecast, feeling even colder with wind chill. Snow accumulations of 2-5cm are expected, with up to 10cm possible on higher ground.
Scotland and Northern Ireland face the worst conditions, with amber warnings active across central and eastern Scotland indicating significant snowfall and disruption. Rural and upland areas could see temperatures drop to -10°C overnight, whilst wind speeds of 20-30 mph will make conditions feel exceptionally bitter. Widespread ice poses a major risk on untreated surfaces.
Wales remains under yellow warnings for ice and snow, particularly affecting higher ground in northern and central areas. Coastal regions will experience strong winds with gusts up to 40 mph, adding to the chill factor. Daytime temperatures are unlikely to exceed 2°C, with overnight values dipping well below zero.
The Met Office is urging the public to exercise extreme caution, advising people to check weather forecasts and road conditions before travelling, allow extra time for journeys, and dress in layers. Pedestrians should watch for slippery surfaces, whilst vulnerable residents are encouraged to keep warm and check on neighbours.
The cold snap marks a dramatic shift from the relatively mild autumn weather, as winter takes hold across Britain. The public should monitor Met Office warnings, which may change as the weather system develops.
