A weather chart appears to turn black as a blistering heatwave sweeps across much of the nation this week. Temperatures could tip to as high as 32C on Friday as the searing conditions bake Britain for around 48-hours. According to the WxCharts, hotter air will start to move across parts of the nation on Thursday afternoon.
Temperatures are then expected to soar on Friday as the colour of the weather chart turns from a dark red shade to black, suggesting warmer conditions.
The hot air appears to then quickly sweep past Britain, with cooler temperatures then likely to move in on Saturday afternoon.
The latest weather maps by Netweather also suggest warmer air will move across Britain later this week.
Temperature charts show conditions hitting 30C in London on Friday, and widely across England, Wales and parts of Scotland between 24C to 28C.
On Saturday thermometers are also expected to reach 26C in parts of the capital.
And The Weather Channel claims the UK could even see highs of 32C on Friday.
Forecaster Brian Gaze from The Weather Outlook, warned of a week of mixed conditions before the warmer air moves in.
He said: “Wednesday is looking mainly dry and bright. Temperatures will be higher than in recent days and in the south, it should feel quite warm.
It is set to turn much warmer and the last day of the month could see 30C (86F) being exceeded in the south

“During Thursday and Friday outbreaks of rain are possible in the northwest. Other areas have a lot of dry and sunny weather.
“It is set to turn much warmer and the last day of the month could see 30C (86F) being exceeded in the south.
“Through the weekend cooler air returns southeastwards and there is a risk of heavy showers or thunderstorms for a time.
“By Sunday showers could become restricted to central and eastern counties as a ridge of high pressure builds in from the west.”
The Met Office also predicts hotter temperatures towards the end of this week but warns the warm conditions will quickly change.
The weather service’s long-range weather forecast from Friday, July 31 to Sunday, August 9, claims the UK will soon face “scattered showers and thunderstorms”.
Its outlook said: “A brief very warm spell is likely for many areas at the end of this week with a good deal of sunshine, although increasing cloud may bring rain to the northwest.
“It may become hot in southeastern areas. However, scattered showers and thunderstorms will probably introduce cooler, more changeable conditions from the west next weekend.
“Through early August changeable weather is likely to continue with bands of rain, perhaps accompanied by strong winds, interspersed with brighter, showery conditions.
“However, all areas should have some dry spells, these most likely in the east, with a better chance of dry spells more generally late in the period.
“It is likely to be on the cool side for western areas, but with temperatures closer to average across the east and southeast.”
And, before the hot blast later this week, forecasters have warned of unsettled conditions for some parts of the nation.
Looking at Tuesday’s forecast, the Met Office said: “Cool and showery in northwestern parts of the UK but largely dry further southeast with only isolated showers. Persistent heavy rain and gales, locally severe, continuing for northern Scotland.”
And its outlook for Wednesday to Friday added: “Most places dry Wednesday with lighter winds. Bright for many Thursday but rain may reach northwestern areas. Friday, sunny and very warm, perhaps hot, though with thundery showers possible later.”
It comes as leading bookmakers have slashed odds on the UK to see the wettest day of the year being recorded this week.
Alex Apati of Ladbrokes said: “It looks like summer could be cut short with record-breaking rain for the year likely to fall over the coming days.”
