Thunderstorms in parts of UK but staying hot.
Parts of England and Wales could face “torrential downpours” as thunderstorms move in over the course of Thursday evening.
There could be some heavy and thundery downpours, mainly across parts of the Midlands and East Anglia.
Outbreaks of rain will also affect western fringes of Ireland and northwest Scotland.
There is also a warning of sudden flooding, affecting transport routes, homes and businesses.
Northern England, the Midlands, Yorkshire, Lincolnshire and East Anglia are the most likely areas to see heavy showers, while some areas could also have hail and lightning.
London, the Midlands and up into Lincolnshire have seen the highest temperatures.
Cooler air is filtering down from the North West over the next few days, but it will remain very warm in the South East with temperatures into the high 20s over the weekend.
Environment Agency flood duty manager Chris Wilding said: “Thunderstorms and intense, heavy rain are possible across parts of the country on Thursday and in eastern England during the early hours of Friday morning.
“This could lead to localised flooding and disruption to travel, particularly in urban areas.”
