30-Hour Snow Bomb to Hit UK: 15cm Deep and 560-Mile Span
UK Braces for 30-Hour Snow Bomb, Up to 15cm Deep

The United Kingdom is preparing for a significant and prolonged winter weather event, with forecasters predicting a 30-hour continuous snow event set to begin on Monday, January 26.

Widespread Snowfall Across the Nation

Maps from WX Charts, utilising Met Desk data, indicate a vast swathe of the country will be affected. The snow is expected to cover an impressive 560-mile stretch, from Birmingham and the West Midlands conurbation all the way north to Wick on the tip of Scotland and John O'Groats.

While other regions may see milder conditions, this central and northern corridor is braced for a substantial dusting. The system is projected to sweep across the area starting around 6pm on January 26, with snow cover becoming widespread by midnight on January 27.

Significant Accumulations Expected

Accumulations of snow are likely to be significant in many areas, with predictions of up to 15 centimetres (6 inches) of snow in some locations. The deepest snow is currently forecast for the high ground within the Cairngorms National Park in Scotland.

The BBC Weather team has highlighted increasing uncertainty for next week's forecast, noting a battle between weather patterns. They stated: "Next week there is increasing uncertainty, with two contradictory weather patterns trying to establish themselves."

Uncertainty in the Longer-Term Forecast

Initially, Atlantic low-pressure systems are expected to bring unsettled weather with rain. However, there are signs that high pressure over Scandinavia could later build, potentially bringing colder easterly winds and an increased risk of wintry showers from the North Sea by the week's end.

The forecasters caution that confidence decreases substantially later next week. The BBC update added: "Bear in mind, however, the milder Atlantic-driven weather regime could win out, even if only in western regions."

Residents across the affected regions are advised to monitor the latest weather warnings from the Met Office and prepare for potential travel disruption during the prolonged 30-hour snowfall period.
