Record-breaking temperatures could hit parts of Britain for the rest of the week as the school holidays get under way.
Temperatures will increase as the week progresses, according to forecasters, reaching highs of 33C on Tuesday, 34C on Wednesday and 35C on Thursday.
The mercury needs to reach at least 25C for three consecutive days for the majority of the UK to be classified as a heatwave.
Although the main concentration of the hot weather will be in central and south-eastern England, parts of Scotland could reach the high 20s.
However, the humid conditions are expected to lead to thundery showers in Bristol on Tuesday evening and the early hours of Wednesday morning.
Marco Petagna, a Met Office forecaster said there was the potential for record-breaking temperatures by Thursday evening.
He said there was a “60% chance” Thursday’s weather might surpass the July record of 36.7C (98.06F) set at Heathrow in 2015 and a “30% chance” of going over the al- time UK temperature record of 38.5C (101.3F), which was recorded in Faversham in August 2003.
Petagna added: “On Thursday we’ll see an east and west split with showers in the western parts of England but the eastern parts will look very hot with 36 to 37C (96.8F).”
Petagna also warned “anywhere across England could see some thundery showers”.
The forecaster said the coolest areas will be in western England where temperatures will remain in the 20s.
Ruth May, the chief nursing officer for England, has urged people to check on their neighbours during the warm weather. She said people should take care as temperatures rise, while Asthma UK urged sufferers to keep up their medication.
May said: “The NHS will be there always for anyone who needs it, but everyone can help by checking in on vulnerable friends and neighbours, while making use of the free, convenient and helpful phone and online NHS services for minor illnesses, to help frontline staff provide care for those in emergency and serious need.”
Meanwhile, a dog welfare charity has advised owners to not leave pets alone in a hot car seat even for a few minutes. Dogs Trust says on a day where the temperature is 22C, inside a car it could rise by 11C in 10 minutes and dogs cannot cool down the same way as humans.
Earlier this week, an American bulldog received treatment after his body temperature soared to a life-threatening temperature 42.2C in Glasgow.
Paula Boyden, Dogs Trust’s veterinary director, said: “There are so many things we can do to make sure our dogs stay happy and healthy in hot weather, but it is crucial we keep a close eye on them, even if we are playing indoors.
“If we all do this, then hopefully we and our dogs will be able to enjoy a long hot summer.”
