Brits are preparing for a hot, muggy, and 'sticky' day ahead with forecasts as high as 31C today.
The UK could see a new record with the hottest day of the year so far if mercury surpasses 30C.
The Met Office has said there is a 'good chance' that temperatures could sizzle later on Wednesday but will bring a muggy feeling by the early evening.
A warm front stretching south east from East Anglia to Kent and encompassing London means areas inside the zone are likely to bask in the hot weather.
Regions in the north will enjoy cooler temperatures and may see a few showers over Scotland and Northern Ireland.
The Met Office forecast highs of 30C will be seen in London with 22C in Cardiff, 18C in Belfast, and a colder 17C in Edinburgh.
Monday marked the hottest day of the year so far when temperatures soared to 29.7C in Teddington, Middlesex.
Now the weather agency says there is a "reasonable chance" the warmer weather could surpass the record set only two days ago.

Simon Patridge, meteorologist, said: "It's going to be pretty close and there's a reasonable chance that we will just pip it.
"There's a good chance that we could see 30C temperatures just north of London and a small chance of seeing 31C.
"The heat will be very much concentrated in the south-east corner of the UK, with a cold front across more northern areas.

"As well as being very hot it will become increasingly humid, so it's going to feel really quite sticky and muggy by the early evening."
He added the dry, cloudy weather bringing 15C will help footie fans in Wales as the country takes on Turkey in the Euros at 5pm.
However, fans watching in east Wales and England may see a different story as a yellow weather warning for thunderstorms and torrential rain is in place from 6pm on Wednesday until midnight Thursday.
The Met Office also issued a weather alert for storms which could cause flooding and power cuts in the south east of the country to last 24 hours from 9am on Friday.
The downpours could help the muggy and 'sticky' feeling Brits suffer in the potential record-high sunshine.
The warning covers areas based in the south east of Hull, including Birmingham, and areas in the south excluding Devon.
Those further west from Manchester and most of Wales may see rainfall on Thursday but should escape the second round of thunderstorms.
