The Met Office has issued an update on when the cold snap in the UK will come to an end, with temperatures expected to rise soon. According to Wales Online, Arctic winds will cause temperatures to plummet, bringing more autumnal weather. However, this cold spell is not predicted to last long. Early on Tuesday, a deepening area of low pressure is set to move east across northern parts of the UK, bringing rain and strong winds. Motorists on A55 Britannia Bridge in Anglesey were warned of strong winds on Tuesday morning.
The Met Office’s forecast for Wales indicates a mostly cloudy morning with showers, leading to more general rain from the north. Temperatures will drop significantly, turning “markedly cold” as a showery airmass spreads across the UK by mid-week, potentially bringing hail and thunder in some areas. Showers may even turn wintry over Scottish mountains. Met Office Chief Meteorologist Andy Page highlighted concerns about heavy rain near Shetland, prompting a yellow weather warning for rain. Northwesterly winds are also being monitored, especially in Orkney and parts of Moray and Aberdeenshire.
Looking ahead, Wales can expect a changeable and blustery day on Wednesday with sunny spells and showers, some heavy with possible hail. The weather will be cool for mid-September, particularly due to brisk winds. Thursday will remain breezy and cool with sunny spells and showers. However, Friday and Saturday are expected to be dry with sunny spells. Although there may be some chilly nights initially, temperatures are set to return to average by Saturday.
Despite the current cold snap, milder air from the Atlantic is anticipated to move back across the UK later in the week, bringing temperatures closer to average for this time of year. The long-range forecast from Saturday, September 14, to Monday, September 23, suggests more settled weather with high pressure building in the middle of the following week. The outlook includes cloudy conditions with rain in northwestern areas on Saturday, becoming drier in southern and eastern regions. The forecast hints at rain or showers, particularly in western and northwestern parts early next week, with a trend towards higher pressure from midweek onwards. Following a chilly start to the weekend, temperatures are expected to return to near-normal levels for mid-September, potentially even above-average in some locations.
