Britons are bracing for a sharp drop in temperatures and the possibility of up to nine inches of snowfall across 16 counties in England and Wales, with Scotland also expecting wintry conditions. The current weather disturbance, Storm Bram, is causing strong winds and heavy rainfall across the country. However, as the system moves away later this week, milder temperatures of up to 16 degrees Celsius are expected before a cold Arctic air mass descends just ahead of Christmas.
Weather maps indicate that low-pressure systems will sweep into the UK throughout the month, leading to unsettled conditions. By December 19, the collision of these systems with cold Arctic air is likely to trigger widespread snowfall. Temperatures are forecasted to hover near zero on Friday, December 19, and may plummet to -1 degree Celsius in central Scotland.
According to WXCharts, snowfall is projected to extend as far south as Devon in southwest England, potentially causing travel disruptions on December 20. Sixteen counties in England and Wales, including Yorkshire, Cumbria, and Lancashire, are anticipated to experience snowflakes on December 19. While snow accumulations are expected to be minimal in most areas, heavier snowfall is predicted along the west coast of Scotland, possibly reaching depths of up to 23cm or nine inches on December 20.
The Met Office’s forecast from December 14-23 points to weather systems moving in from the Atlantic, signaling a likelihood of falling temperatures later in the month and an increased risk of wintry conditions. The agency warns of intermittent rain spells, potential impacts due to recent wet conditions, and the chance of strong winds. While mild weather is expected initially, a decrease in temperatures towards the end of the period, especially in northern regions, may bring drier intervals and a heightened risk of wintry weather in the north.
