BBC weather forecaster Carol Kirkwood claimed temperatures could rocket as much of the country is forecast dry weather with sunshine.
Kirkwood predicted a ‚Äúlot of sunshine around‚ÄĚ for England and Wales as the ‚Äúheatwave was by no means finished with us just yet‚ÄĚ.
It comes as the Met Office has issued an amber weather warning urging people to keep out of the sun when it is at its strongest.
The BBC forecaster,¬†Kirkwood, said: ‚ÄúThe forecast this week is one of sunshine. There will be some showers in the forecast. But the showers, not all of us will see them, and we are going to hang on to the hot and humid conditions.
‚ÄúIn the charts, you can see that we have a weather front moving southeast-wards it‚Äôs producing some rain currently across Scotland and Northern Ireland.
‚ÄúFor northern¬†England,¬†there is quite a lot of cloud around and that is producing some showers across the isle of man, north-west England. Also in north and west Wales. But northeast England heading down to the Midlands, East Anglia, southern counties, there is some patchy cloud but it is dry and it is a funny start.
‚ÄúFor west Wales and southwest England, you too have a bit more cloud around. But nonetheless still some brighter breaks, particularly east Wales.
‚ÄúThrough the day what you will find is that weather front will very slowly take its rain moving southeastwards. It won‚Äôt get as far as the borders.
‚ÄúAhead of it there will be a few showers and behind¬†it,¬†we are looking at sunshine and showers. But for England and¬†Wales,¬†there will be a lot of sunshine around. One or two sunshine and showers in southwest England but they will be few and far between.
‚ÄúTemperatures up to 31C or 32C in the London area. Widely the mid to high 20C‚Äôs. Locally in the northwest of¬†Scotland,¬†we are looking at 16C.‚ÄĚ
The Met Office level-3 heatwave action warning urges people to keep away from the sun between 11am and 3pm.
It reads: “There is a 90 percent probability of heatwave conditions between 0900 on Monday and 0900 on Friday in parts of England.
“Stay out of the sun. Keep your home as cool as possible ‚Äď shading windows and shutting them during the day may help.
“Open them when it is cooler at night. Keep drinking fluids. If there’s anybody you know, for example an older person living on their own, who might be at special risk, make sure they know what to do.”
The amber, or level three, warning is issued when temperatures are predicted to hit 30 degrees during the day, and 15 degrees at night, for at least two consecutive days.
Eastern and southeastern regions of the UK are expected to face the highest temperatures this week although Scotland and northern England could also reach the 30C mark.
Met Office meteorologist Alex Burkill said: ‚ÄúTowards the east and southeast it is going to be mostly fine, hot and sunny through next week with highs of 31C or 32C from Monday.
‚ÄúWe expect similar values on Tuesday but as we go through the week it is going to turn even hotter.
‚ÄúWe are likely to see temperatures of 33C or 34C by Wednesday or Thursday in the southeast and 35C is not out of the question.
‚ÄúThe hot weather looks like continuing all next week and beyond especially in eastern and southeastern parts of the country.‚ÄĚ
The all-time UK record of 38.5C set in Faversham, Kent, in August 2003, could also be reached by the end of summer according to some experts.
James Madden,¬†a forecaster¬†for Exacta Weather, said: ‚ÄúThis week will bring another period of very hot weather particularly across the south of the country where we could see temperatures approaching the mid 30Cs by the middle part of the week.
‚ÄúTemperatures will remain well above average elsewhere despite some occasional showers and some cloud cover in northern and western areas.
‚ÄúThis weather pattern is likely to stick around into August especially across the south and southeast where it is looking very warm¬†through¬†the forecast period.‚ÄĚ
Leading bookmaker Ladbrokes has slashed odds to 1/3 that the hottest day of 2018 could fall during this month.
Jessica Bridge of Ladbrokes said: “Mother Nature’s generosity with the sunshine is showing no signs of slowing down any time soon, and the odds suggest we could be on course for even more record-breaking temperatures.”
