Temperatures are expected to reach 29C in just a few days after mercury reached record-breaking highs.
The south east and East of England will witness potential highs of 29C at 3pm on Saturday, WXCharts has claimed.
Mercury could reach 28C in the north east of England and Londoners could bask in around 26C.
Warmer temperatures fall just short of what is expected on the other side of the Channel.

Warm temperatures across the east come after the Met Office said last month’s provisional figures indicated both the overall average and the average maximum temperatures were the highest since records began in the 1880s.

The average monthly temperature of 15.8C exceeded the previous highest average June temperature by 0.9C.
The previous records were set in 1940 and 1976.
The Met Office’s Mark McCarthy said: “It’s officially the hottest June on record for the UK, for mean temperature as well as average maximum and minimum temperature.
“June started with a good deal of high pressure and temperatures initially around average for many, but once that subsided, warm, humid air began to influence temperatures, with 32.2C the highest temperatures reached.
“What’s striking is the persistent warmth for much of the month, with temperatures widely into the mid 20s for many and even into the low 30s at times.”

The Met Office’s Tuesday forecast said: “Rain, occasionally heavy, across the south will only slowly clear eastwards throughout the day.
“Cloud and rain also affecting parts of Scotland and Northern Ireland, with sunshine and showers elsewhere.”
Looking ahead to later this week, the UK’s national weather service added: “Another showery day on Wednesday, before showers ease from the west on Thursday.
“Drier and warmer for many on Friday, but further rain likely for Northern Ireland and western Scotland.”
