Weather maps reveal exact date 17C Iberian plume could sweep across UK
Temperatures could climb to 17C in parts of the south of England on November 1, weather maps suggest - with the Met Office noting that 'above average temperatures are more likely'
Despite a chilly weekend which saw temperatures dip "below average" across the UK, winter isn't ready to take hold just yet. New weather maps suggest a warm surge from the Iberian jet stream could soon sweep across Britain.
WXCharts suggests that temperatures could climb to around 17C in parts of the south of England as early as 6am on November 1. London, Surrey, Buckinghamshire and Hampshire are set for highs near 16C, with the Isle of Wight possibly hitting 17C.
Elsewhere, areas such as Kent, Wiltshire, Essex, Suffolk, Northamptonshire, Cambridgeshire and Lincolnshire may also see maximum temperatures of around 15C.
According to UK forecaster Netweather, the jet stream is expected to be in full force by 9am on November 1, sweeping across Europe, including France, Spain and Portugal.
The jet stream - a fast-moving ribbon of air high in the atmosphere - generally races from west to east across the Atlantic to Europe. Depending on its position, it can put the UK on either its colder or warmer side.
While the jet stream is a natural phenomenon not caused by the climate crisis, experts say our warming planet is making Iberian jet streams stronger and more frequent, driving extreme weather such as heatwaves and wildfires across Europe.
The Met Office's long range forecast for November 1 to November 10 says "above average temperatures are more likely, especially at first". We can also expect fewer overnight frosts or fogs than normal.
However, the weather agency warns the start of November will continue to bring "changeable and at times unsettled weather", with low pressure dominating much of the UK.
The Met Office continues: "This means further showers or longer spells of rain at times. All parts could see some heavy rain at times, but it is likely that western areas will be wettest. Equally there should also be some, at least brief, drier or clearer interludes, these most prevalent further east."
The UK’s warmest November on record came in 2015, when Trawsgoed, Wales reached a scorching 22.3C - a record also linked to the jet stream. The previous record, 21.7C in Prestatyn, Wales, dated back to 1946.
