Parts of the UK experienced their first air frost of the season this week as a surge of Arctic air brought chilly temperatures and heavy showers across the country. However, a shift in weather patterns promises a warmer weekend, with temperatures potentially rising above seasonal norms.
Chilly Start to Autumn
The arrival of Arctic air this week resulted in below-average temperatures, cascading down from northern Scotland and affecting regions throughout the UK. In some areas, significant showers occurred, and mountain tops in Scotland even received a dusting of snow. Notably, Topcliffe in North Yorkshire recorded temperatures plummeting to -2.7°C on Thursday night, marking the earliest air frost in England in five years. This trend was echoed in Wales, which also experienced its earliest frost in five years, while Northern Ireland saw its first frost in four years.
Regional Temperature Variations
Temperatures across the UK during mid-September typically range from 14°C in northern Scotland to 19°C in the south-east of England. However, this week, many locations recorded temperatures two to three degrees below the norm. In Scotland, temperatures dipped below freezing, reaching -2.5°C at Eskdalemuir, though the region had already experienced frost earlier this season.
The current conditions underscore the impact of wind patterns on weather. Cold north-westerly winds have dominated the past few days, bringing a distinctive chill to many areas. While snowfalls were limited primarily to mountainous regions, hail was reported in some heavy downpours.
A Warm-Up on the Horizon
As the weekend approaches, forecasts indicate a significant shift in the weather. The cold north-westerly winds will give way to milder south-westerly winds, allowing a warmer air mass to move in from the continent. This transition could see temperatures climbing back towards seasonal averages, with highs expected to range from 14°C to 20°C across various parts of the UK.
Forecast for the Weekend
While the weekend weather looks promising, it will not be entirely dry. A frontal system is set to bring clouds and sporadic rain, particularly affecting northern and western regions. The south-east, however, is anticipated to undergo less rainfall.
Early next week, higher pressure is predicted to establish itself firmly over the UK, leading to further increases in temperature. Some areas in Scotland, Northern Ireland, and Wales might experience highs of 19°C or 20°C, with parts of England potentially reaching between 23°C to 24°C by Wednesday. This would represent a notable departure from the preceding cold spells, providing a warmer and more comfortable atmosphere for residents.
Longer-Term Outlook
Looking ahead, there is currently no strong indication that colder northerly winds will return before the end of the month. The upcoming warm spell may offer a welcome reprieve from the recent chill, allowing residents to enjoy more seasonal weather.
