Britain is preparing for a 21-hour snow event as new weather maps reveal the timing and locations of the anticipated snowfall. The wintry showers are expected to commence in Scotland on December 15, then progress southward to Northern Ireland, Wales, and parts of northern England. By 9 am, the heaviest snowfall is forecasted in southern Scotland’s Galloway Forest Park, the Lake District, and the Pennines, with lighter snow expected in Northern Ireland.
North Wales, particularly Snowdonia, is set to experience heavy snow by 3 pm on the same day. As the weather system moves down the British Isles, areas that escape the snowfall may experience rain instead, with central and northern England likely to encounter downpours throughout the day.
Snow coverage maps for 9 pm on December 15 indicate significant snow accumulations in various parts of the country. After 21 hours of snowfall, several inches of snow are projected to blanket North Wales, Northern Ireland, northern regions of England including West and North Yorkshire, and most of Scotland.
The Met Office has hinted at the possibility of snowfall in some UK areas during the latter half of December. Their long-range forecast from December 16th to 30th suggests a higher likelihood of dry weather due to potential high-pressure systems, with chances of overnight fog and frost. Despite this, intermittent spells of rain, showers, and strong winds are expected, especially in the west, with possible hill snow mainly in the north. Overall, temperatures are predicted to be near or slightly above average, although colder intervals are also plausible, particularly if prolonged settled weather occurs.
Bookmakers have shortened the odds on a White Christmas this year, with Coral’s John Hill noting a surge in bets for snow on December 25. The last official White Christmas was in 2023, while significant snowfall across the UK was recorded in 2010, with 83% of weather stations reporting snow on Christmas Day that year.
