The Met Office has extended the red extreme heat warning to tomorrow (Friday, June 26), as temperatures are set to remain high across Oxfordshire.
The record-breaking June heat is expected to continue into Friday according to the forecaster, as temperatures remain at 34C.
This comes as the UK's recorded its hottest June day record was broken for a third time, with highs of 36C in Surrey and Hampshire, surpassing the 1976 35C record.
The breaking of the 50-year record came as the Met Office issued a red extreme heat warning for the county and other parts of the south east of England from 9am on Wednesday, June 24, now extended until 9pm on Friday, June 26.
If temperatures reach 39C, that would make it the second hottest day in the UK on record.
If 38C is recorded, that is still in the top five days ever recorded and hotter than any day of the 20th century.

The heatwave has closed more than 100 schools across the county over the last few days, and disrupted rail services, particularly between London Paddington and Reading.
