SUSSEX is set for a somewhat disappointing weekend weather-wise as parts of the UK brace themselves for the “hottest weekend of the year”.

While Brighton will enjoy some sunshine tomorrow morning, clouds will move in by lunchtime and persist well into next week, according to the Met Office.

However, conditions are expected to remain dry, with temperatures reaching a high of 18C tomorrow and a slightly cooler 15C on Sunday.

The forecast comes as the country prepares for the Queen's Platinum Jubilee, with some meteorologists anticipating that the four-day weekend could be the hottest of the year so far.

British Weather Services senior meteorologist Jim Dale said: "On the run into that weekend we might see something that's a little bit warmer - maybe even very warm."

"So basically sunny, dry in the main universally and also very warm, increasingly so as you go through the course of the weekend.

"And I don't just mean London that's going to be 27C - it might also be Edinburgh.

"So this could be the warmest weekend universally of the year to date. That's what it's looking like, with the caveat that we're still some distance away.

 “I think as we approach that weekend it might well ramp up."

Looking ahead from June 1, the national weather service said: "Eastern areas are likely to be cloudier with a higher risk of showers and breezier at the start of this period, with drier weather and the best of the sunshine probably in the west.

“The east is also expected to see cooler than average temperatures over this period. Into the rest of next week, it will likely be mainly fine and dry, but occasional rain and showers, mainly in the east.

“Feeling warm in any sunshine. Towards the bank holiday weekend, this pattern is likely to continue, with some dry weather and sunny spells."
