Weather forecaster Jim Dale told Express.co.uk that the UK could see "very warm", dry and sunny weather over the Jubilee weekend, running from Thursday, June 2 to Sunday, June 5. While Mr Dale warned that the weather leading up to the bank holiday will be "chequered", with some rain and showers around, the forecaster said it will clear up by the time the Jubilee festivities get underway.
However, he warned that the country may also see some thunderstorms in the southeast towards the end of the weekend. Mr Dale, senior meteorologist at British Weather Services, told Express.co.uk: "The run-up to it is chequered, it's mixed, it's not that warm.
"Don't get me wrong, it's warm enough - I never complain at 17C, 18C, but it's not 20Cs, so the road is chequered. There will be rain around and showers all the way through next week. Around May 30 we're seeing high pressure coming in from the south east. It's a good direction, a warming direction.
"So that little run-up before you actually get to the second of June, it's decent, it's warming. And you are going to see into the 20s. And that's everywhere, most parts of the country. So it's warming up nicely."
