Festivalgoers and event attendees across parts of the United Kingdom are facing disruptive weather as the Met Office has issued a yellow warning for thunderstorms and heavy showers. The warning, active until 9 p.m. on Saturday, covers areas from southwest England and parts of Wales, extending across the Midlands to the east of England. Residents and businesses in these regions are cautioned about an increased risk of flooding, potential train delays, and longer travel times for road journeys. Some areas could experience 15 to 25 millimeters of rain within an hour, with 30 millimeters possible over two to three hours, accompanied by hail and lightning.

The current weather pattern is attributed to an area of low pressure moving eastwards across England and Wales, bringing rain that will be followed by heavy showers. Met Office meteorologist Greg Dewhurst noted that while temperatures would generally be in the low 20s Celsius, reaching highs of 22 to 23 C, the conditions would differ in Scotland, which is expected to see some brighter spells despite cloud cover.

Sunday is forecast to bring a mix of sunshine and showers, particularly in the north and west of the UK, with some thundery activity. Temperatures are expected to be slightly higher due to more sunshine, potentially reaching 20 to 23 C, with isolated areas possibly reaching 24 C. Monday is anticipated to be brighter for most, though with increased cloud and showers, more frequent in the north. Temperatures may slightly decrease, ranging from 19 to 22 C, with a possibility of 23 C in some locations.

Clouds gathering at Leeds Festival on Saturday.

Wind gusts of 35 to 40 mph are also possible along the south coast on Saturday. Leeds Festival could experience gusty winds on Sunday if heavier showers materialize. The wet weather follows a period of continued high temperatures across the UK, which had contributed to extremely dry conditions. This shift in weather has led to festivalgoers at events like Reading and Leeds being pictured in ponchos and wellington boots, with some artists warning attendees about the conditions within tents. Cricket fans at Lord's in London also encountered rain on day three of a Test match. Environment Agency flood alerts have been issued for four areas, primarily across the Midlands, indicating a possibility of localized flooding.
