The Met Office has issued a new yellow warning for heavy showers and thunderstorms, with festivalgoers set to face more wet weather.
The warning stretches from south-west England and parts of Wales across the Midlands to the east of England, and will be in force from midday until 9pm on Saturday.
Flooding and travel disruption possible
It means flooding of a few homes and businesses is likely, trains could be delayed and car journeys could take longer, the forecaster said.
Some areas within the warning could see 15-25mm of rain in an hour, and 30mm in two to three hours, along with hail and lightning.
Festivalgoers and cricket affected
Meanwhile, people at Reading, Leeds and other live music events are likely to see rain on Saturday as low pressure pushes eastwards, which will be followed by heavy showers.
The cricket is likely to be affected by showers at Lord’s in London, the Met Office added.
Five areas, mainly across the Midlands, are covered by Environment Agency flood alerts, meaning floods are possible.
Context of hot weather
It comes after continued hot weather across the UK, which coincided with extremely dry conditions.
The Met Office has previously said the UK is on course for its hottest summer on record after five heatwaves, with temperatures of up to 38.1C recorded in London.
