In early November, the UK is experiencing an unusually mild period, with temperatures significantly above the seasonal norm. However, the latest 10-day forecast from the Met Office indicates that this calm and warm spell will soon end, giving way to more unsettled and changeable weather as the new working week begins.
The prevailing weather pattern is influenced by a highly wavy jet stream across the Atlantic Ocean. This jet stream creates a series of dips and troughs, including one moving down towards Iberia. Over the next few days, this trough will deepen, anchoring low pressure to the south and gradually shifting it northward towards the UK by the weekend.
As the weekend unfolds, another dip in the jet stream is expected, forming a wider trough over the Atlantic. This fluctuating jet stream contributes to slow-moving weather systems next week, causing a dynamic interplay between low pressure to the west and high pressure to the east of the UK.
One of the standout features of this period is the warm temperatures for November. On Thursday, highs are forecast to reach mid to high teens Celsius, with some places seeing 15, 16, or even 17°C. These temperatures are roughly six to seven degrees above the average for this time of year.
Bonfire Night 2025 was record-breaking. Temperatures overnight only dropped to 14°C.
Such mild conditions are unusual for November and highlight the current weather pattern's impact on the UK climate.
Author’s summary: The UK’s mild early November is set to end as a complex Atlantic jet stream pattern brings unsettled weather and a battle between low and high pressures next week.
