Looking at the long-range forecast, Met Office forecaster Charlie Powell said Prince Harry and Meghan Markle could be in luck on their wedding day on May 19.
That would make it the hottest Mayday holiday since records began 40 years ago.
The May Bank Holiday was introduced in 1978 and the temperature has never topped 28C.
On the first official May Bank Holiday in 1999 the thermometer peaked at 23.6C, and before that, in 1995, we hit 28.6C, - with it touch and go whether we will sizzle above that.
The brief spell of summer weather is due to hot air coming in from 86F (30C) southern Russian Federation, leading meteorologists to dub the heatwave the "Roast from Russia".
Of Rihanna's Best Fashion Moments At The Met Gala
However, on the red carpet, a variety of celebs are wearing their own interpretation of the religious theme. In 2014, Rihanna chose to stick to her usual crop-top style but put a red-carpet spin on it.
Today, temperatures are expected to peak at about 20C (68F) in the county. You would then start to see cloud and you could start to see patchy rain.
The South East and central southern England are experiencing the most heat, with the majority of the United Kingdom seeing temperatures between 23C (73.4F) and 27C (80.6F).
The highest temperature of the day is likely to be in or just west of the London area where 29 °C is possible, smashing the previous record high for early May Bank Holiday Monday.
But forecasters warned the heatwave is not set to last, with the weather for the rest of the month described as "changeable".
Andy Page, Chief Meteorologist at the Met Office said: "Most of us will continue to have blue skies and sunshine on Bank Holiday Monday, although parts of the far north and northwest of Scotland will be cloudier with the chance of some rain, and it will be misty and chilly around some Irish Sea coasts".
Emmanuel Macron's White House Sapling Has Disappeared
Also puzzling is why the White House didn't announce in advance that the planting last week was a purely symbolic event. Meanwhile, Huffington Post quotes an unnamed official at the Elysée Palace, who said the tree is under quarantine.
"But I think we can expect things to be not as warm as they are now".
"We're still going to see some dry days, but there's still going to be some wet days mixed in as well".
This weekend's hot conditions have been created by a mix of low pressure, light winds and consistent sunshine.
He said temperatures will generally be above normal, but this will depend on whether it is a sunny day or a sunny wetter day.
