Brits are being cautioned about an impending weather clash over the UK as meteorologists foresee a confrontation between mild Atlantic air and frigid easterly winds, heightening the possibility of snowfall and significant drops in temperatures towards the end of the month.
The Met Office has indicated an increased likelihood of colder weather returning later in January following the impacts of Storm Goretti, which brought snow, heavy rainfall, and near-hurricane-force winds to various parts of the country earlier this month. Meteorologist Greg Dewhurst has highlighted the upcoming period as a pivotal moment, mentioning that a weather showdown is expected between mild conditions and the potential for colder temperatures in the upcoming weekend and the following week.
Storm Goretti, characterized as a “multi-hazard event,” unleashed gusts nearing 100mph and prompted a rare red weather warning for stormy winds in the south-west of England. Tragically, a man in his 50s lost his life when a tree fell on his caravan in Helston, Cornwall, amidst flight cancellations, train disruptions, and numerous school closures. The ongoing concern now is which weather system will ultimately prevail.
The Met Office described the situation as a clash between Atlantic weather systems pushing in from the west and high pressure along with colder conditions influencing the east. Initially, a dominance of milder Atlantic air is anticipated, leading to cloudy, unsettled weather with showers and temperatures near average.
Yet, forecasters caution that the scenario could shift, with the potential for a transition to colder weather that could bring snow to various parts of the UK. Weather projections from WXCharts indicate a possible incursion of Arctic air, known as the ‘Beast from the East,’ advancing westward by mid-week next week. The data suggests snowfall starting on January 27, initially impacting Wales, Scotland, and Northern Ireland before spreading rapidly southward and eastward.
Snowfall intensity could increase during the day, with rates of up to 0.4 inches per hour expected from Colchester to just below Inverness by early evening. The return of snow is foreseen on January 29, enveloping the UK from north to south, covering a span of over 600 miles, with accumulations of up to two inches in many regions.
By the early hours of January 30, only select areas such as London, parts of the east coast, and portions of south Wales may escape the snowfall. Simultaneously, temperatures are set to plummet, with overnight lows ranging from -1C to -6C across England, approximately -5C in Wales, and potentially as low as -12C in parts of Scotland, particularly near Inverness, where snow is expected to persist.
However, Met Office spokesperson Grahame advised caution, emphasizing that the deep freeze is not a definite outcome. While a shift to colder weather remains a possibility later in January, it is still too early to guarantee, with current indications suggesting that milder air from the south may continue, warding off the cold for the time being.
