The Met Office has issued its long-range weather forecast for the final week of September, predicting heavy rain and gales set to hit the UK. Maps have revealed that a stormy weather front will move in, with 40mph gales and heavy downpours expected on Wednesday, September 25. The charts also indicate a fast-moving jet stream with winds of up to 100mph, set to impact the UK on the same day.
The jet stream, a core of strong winds located high above the Earth’s surface, will affect much of Britain from the southern coast up to the Scottish Highlands. The forecast shows gusts of winds and significant rainfall spreading across the UK. The Met Office’s long-range outlook from September 21 to September 30 predicts a chance of showers and thunderstorms during this period. The weather will be unsettled in the south, with some sunny spells in central and northern areas.
As temperatures increase, the cold Arctic air will give way to warmer westerlies over the weekend. While rain may be confined to the extreme northwest of Scotland early in the week, high pressure will bring dry and fine conditions for most parts of the UK. Some areas could experience cooler nights with mist or fog developing. The latter part of the week is expected to remain fine and dry, with spells of sunshine for many regions.
Throughout the forecast period, southern areas are likely to see the focus of heavy rain, while the north may enjoy more settled conditions. The increasing temperatures and dry spells will provide relief from the recent chill, according to the Met Office. The overall weather pattern is set to bring a mix of conditions, with milder temperatures and varying precipitation across different parts of the UK.
