“We’ll really start to notice it on Sunday with 25C on the cards, before 31C on Monday and again Tuesday.”
While Thursday and Friday may bring a risk of showers to much of the UK, with temperatures feeling cool.
Speaking about Thursday’s weather, BBC forecaster Phil Avery said “There will be some sunshine to go with that rather chilly start.
“But as I get you on into the afternoon, I think the cloud is going to fill in and the sunshine will become ever more fleeting.
“And not just as warm as we’ve seen it of late.”
