Despite a cool weekend with temperatures dropping below the average range in the UK, winter is not yet fully settling in. Recent weather forecasts indicate a warm surge from the Iberian jet stream that is expected to sweep over Britain.
According to WXCharts, some parts of southern England could experience temperatures reaching around 17C as early as 6 am on November 1. Locations such as London, Surrey, Buckinghamshire, and Hampshire are likely to see highs near 16C, with the Isle of Wight potentially hitting 17C.
In other regions like Kent, Wiltshire, Essex, Suffolk, Northamptonshire, Cambridgeshire, and Lincolnshire, maximum temperatures may reach around 15C.
UK forecaster Netweather predicts that the jet stream will be fully active by 9 am on November 1, moving across Europe, including France, Spain, and Portugal.
The jet stream, a swiftly moving band of air in the upper atmosphere, typically travels from west to east across the Atlantic towards Europe, influencing whether the UK experiences colder or warmer conditions based on its positioning.
While the jet stream is a natural occurrence unrelated to climate change, experts suggest that our warming planet is intensifying and increasing the frequency of Iberian jet streams, leading to extreme weather events like heatwaves and wildfires across Europe.
The Met Office’s extended forecast for November 1 to November 10 indicates a likelihood of above-average temperatures, especially initially, with fewer instances of overnight frosts or fogs than usual.
Nevertheless, the Met Office warns of “changeable and occasionally unsettled weather” at the start of November, with low pressure systems dominating much of the UK. This may result in showers or prolonged spells of rain, particularly in western areas, although some drier or clearer intervals, mostly in the east, are also probable.
The warmest November recorded in the UK was in 2015 when Trawsgoed, Wales reached a high of 22.3C, a record influenced by the jet stream. The previous record of 21.7C in Prestatyn, Wales dated back to 1946.
