Thunderstorms and heavy rain are set to continue across much of the UK through the upcoming bank holiday weekend, with some areas facing the risk of flash flooding. The Met Office has issued a yellow warning for thunderstorms, which covers most of Wales, the Midlands, and parts of northern England. Driving conditions are likely to be affected by spray and standing water, making travel more challenging. Heavy rain has already caused flooding in parts of the Midlands, including Birmingham and Staffordshire, with over 20 flood alerts currently in place. The unsettled weather is expected to persist through Saturday, Sunday, and Bank Holiday Monday, with periods of sunshine mixed with heavy showers and possible thunderstorms across England and Wales. Fresh westerly winds will make the weather feel more blustery, with temperatures ranging from 16°C to 23°C (61°F to 73°F) across the UK. Stronger winds, especially in the south, could create difficulties for those attending outdoor events, including the Reading and Leeds Festivals, Creamfields in Cheshire, Manchester Pride, and the Notting Hill Carnival in London. While some parts of northern and western Scotland may experience drier and sunnier conditions, the overall forecast suggests a mix of rain and sunshine, with the potential for thunderstorms continuing. On Sunday, heavy showers are expected to develop and move eastwards, prompting the Met Office to issue yellow thunderstorm warnings across much of the UK. By Monday, the showers are likely to be less intense, though gusty winds of 30-40 mph are expected in southern areas, making the weather feel cooler than usual. The weekend and bank holiday weather is slightly cooler than average for late August, with temperatures expected to range between 15°C and 22°C. While some relief from the rain may come by Monday, the continued presence of wind and occasional thunderstorms means that the weather will remain unpredictable throughout the holiday period.
