UK to experience 30C heatwave as Iberian jet stream arrives

The UK is set to experience a significant rise in temperatures, with forecasts indicating highs nearing 30C in early September. This surge in heat is attributed to a plume of warm air from continental Europe, driven by the Iberian jet stream. Weather maps reveal that most of the country will see temperatures rise, particularly in Greater London, Southampton, and Bristol, where highs of 28C to 29C are expected. Even traditionally cooler regions in the Midlands and northern England will experience milder temperatures, ranging from 23C to 24C. As the heat intensifies, the Met Office has warned of potential thundery showers between September 5 and 14, which are often associated with hot weather. The forecast suggests that while northern parts of the UK may enjoy drier conditions, southern and eastern regions are likely to face increased humidity and rain. This shift in weather patterns marks a transition from the mixed conditions experienced earlier in the summer. The latter part of the week is expected to see higher pressure over northern areas, while low pressure will linger over the continent, contributing to the unsettled weather. The forecast indicates that the showery conditions will become more widespread, particularly affecting England and Wales, while Scotland and Northern Ireland may remain relatively dry. Overall, the upcoming weather changes signal a notable shift as summer makes a strong comeback, but with the potential for uncomfortable humidity and rain, particularly in southern regions. This pattern may continue into the following week, with central and southern areas remaining susceptible to rain and showers.
