A stormy weather front is set to hit the UK as new maps reveal, with strong gusts and heavy downpours expected in just over a week. On Wednesday, September 25, the UK is preparing for 40mph gales along with significant rainfall, as indicated by the latest forecasts. The charts also suggest the impact of a powerful 100mph jet stream hitting the UK on the same day. The Met Office explains that the jet stream is a band of strong winds around five to seven miles above the Earth’s surface, blowing from west to east. Much of the UK, from the southern coast to the Scottish Highlands, will experience strong winds.
In addition, other maps show that on the same Wednesday, rain is forecasted to sweep through most parts of the UK, with up to 10mm per hour expected along the west coast. The Met Office’s long-range forecast starting from Saturday, September 21, until Monday, September 30, predicts a risk of showers and thunderstorms throughout this period. The Mirror reports that settled but cloudy conditions are expected across central and northern areas over the weekend, with the best sunshine in the west. Showers and thunderstorms are likely in the south during the day, with temperatures above average for most places away from North Sea coasts.
As the week progresses, the risk of showers and thunderstorms in the south is expected to decrease, followed by a brief period of settled weather. However, cloud, rain, and strong winds are anticipated to return from the west, particularly affecting the southern half of the UK. Despite the potential increase in wind speeds, temperatures are predicted to rise compared to recent conditions. The Met Office highlights the transition from cold Arctic air to warmer westerlies over the weekend, with rain confined mainly to northwest Scotland early in the week.
Looking ahead, the latter part of the week appears set to be fine and dry across most areas of the UK, with spells of sunshine expected. The Met Office’s long-range forecast spanning from September 19 to September 28 suggests that although daytime temperatures may be higher than usual, cooler air and patches of mist or fog could develop overnight. Overall, the upcoming weather pattern indicates a mix of conditions ranging from stormy to settled and mild, offering a diverse forecast for the final week of September.
