'It will be a short lived event,' temperatures of up to 29C possible in Ireland this week

"Up to 25C again on Monday with plenty of hazy sunshine," says forecaster Alan O'Reilly. 

He added: "Weather models continue to show a risk of a hot plume around the 17th. Mid thirties in England and possibly up to 29C in Ireland in a worse/best case scenario depending on your outlook.

"Certainly one to keep an eye but it will be a short lived event."
