The scorching 40C heatwave will come to an abrupt end this week as heavy rain is set to fall across much of the UK, according to weather forecasters.
The Met Office have said the blistering heat will cool down dramatically on Wednesday as the scorching weather is set to disappear, with downpours predicted across the country.
Temperatures are expected to drop to a more normal level for this time of year from the middle of the week, as cooler air pushes across the country from the west.
The exceptionally hot weather will cool rapidly on Tuesday night and into Wednesday as the forecasters said there was a "low chance" of storms after the heatwave.
According to the Met Office, scattered showers for central London are expected anytime from 10am to 7pm on Wednesday with risks of rain from 1pm to 4pm in central parts of England.
The Met Office added: “It is likely much of the UK will see temperatures gradually decrease to average or slightly above average through the week, though occasional thundery showers are possible in the south and southwest."
However, there are still some locations in the East of England which could still meet heatwave criteria - with temperatures as high as 30C expected.
The Met Office said: "Although temperatures will fall on Wednesday there will still be some locations in the East of England that could still meet heatwave criteria on Wednesday with, 28-30C still possible.
"With the less hot air moving in from the West there is no specific time the heatwave will end as it will depend on where you are in the UK."
With some parts of the country set to reach temperatures of 40C, the UK is due to be hotter than Tamanrasset in the Sahara (35C) and New Delhi in India (37C).
And in London last night, the temperature recorded at 1am was around 30C - which smashed the current night time record of 23.9C in Brighton, August 1990.
The official end of the heatwave will come as a relief after the intense heat is set to disrupt the UK today and tomorrow as the UK Health Security Agency have issued a level 4 heat health alert.
The Met Office also issued a red warning running from Monday to Wednesday as the heatwave was set to hit record temperatures in the UK.
This has resulted in train companies putting on a reduced service due as Cabinet Office Minister Kit Malthouse warned transport services face "significant disruption" due to the heatwave - urging people not to travel unless absolutely necessary.
Sweaty travellers are already reporting delays this morning - with several London Underground lines experiencing severe delay as millions are expected to stay home as the heatwave forces hospitals to cancel appointments and some schools close.
Water companies have also warned urgent action is needed to conserve supplies in parts of the UK after the rise in temperatures has forced customers to use more water.
Thames Water Andrew Tucker has urged customers to use water carefully, particularly in their back gardens, as the heatwave has led to demand being "at near record level".
Although the company are not currently considering any water restrictions, that could change if there is little rainfall in the coming months.
