The UK is bracing for a potential 12-hour bout of snowfall as the festive period transitions into the New Year, with weather models indicating 11 counties across England and Wales could be significantly affected.
Snow Maps Paint a Wintry Picture
Forecast maps from WX Charts, which utilises data from Met Desk, project the wintry weather to begin around midday on Friday, December 27. The snow is expected to continue for approximately twelve hours, potentially leaving a soft blanket across large areas by midnight.
The counties identified as most at risk span southern and central regions. In the south of England, these include Devon, Somerset, Dorset, Gloucestershire, Wiltshire, and Derbyshire. Further north and in Wales, Cheshire, Glamorgan, Newport, Torfaen, and Yorkshire are also highlighted.
Met Office Urges Caution Amid Colder Spell
However, the national weather service has offered a more cautious perspective. Met Office Chief Meteorologist Jason Kelly addressed the projections, stating that while conditions are turning colder, widespread significant snow is not currently strongly signalled.
"After a spell of unsettled and wet weather, we’re expecting a gradual shift to more settled conditions as high pressure builds into next week," Kelly explained. "This will bring drier and colder weather for many over the Christmas period, with the risk of overnight frost and fog where skies clear."
He acknowledged the possibility of some wintry showers, particularly over higher ground in eastern and southern areas, but emphasised the importance of following official forecasts. "As always, we advise everyone to keep up to date with the latest Met Office forecasts and warnings, especially if you’re making plans over the festive period."
Diverging Forecasts and Falling Temperatures
The discrepancy between the chart projections and the Met Office outlook highlights the uncertainty in longer-range weather modelling. While WX Charts data, supported by Ventusky, suggests temperatures could plunge to around -2°C during this period, the Met Office describes the incoming cold as not unusual for the time of year.
Official forecasters anticipate high pressure building to the northeast of the UK, leading to drier conditions. However, strengthening easterly winds will make it feel notably colder. Where clear skies develop overnight, frost is likely, with mist and fog also possible, especially in the north and west where winds may be lightest.
Residents in the affected counties are advised to monitor the situation closely as the date approaches, given the potential for disruptive weather at a busy travel time.
