Yesterday was the hottest day of the year so far, with Brits basking in temperatures as high as 32.6C. Today the UK is set for similar blistering heat with another record-breaking temperature expected. However, the sunny weather will come to a dramatic end as the good weather is replaced by ferocious thunderstorms and lightning.
NetWeather forecaster Nick Finnis has said “elevated thunderstorms” will break out across South West England and Ireland later today before “spreading north across Ireland, N. Ireland, Wales, Irish Sea and western Scotland through the evening”.
Mr Finnis adds: “Frequent lightning, isolated large hail (2-3cm), strong wind gusts and intense rainfall leading to localised flash-flooding are possible.”
The Met Office has also predicted torrential storms to strike as a violent weather system from the Atlantic makes its way to the UK.
As much as 40mm of rain could fall in under two hours.
The meteorologists have a yellow weather warning in place for parts of the UK from 4pm.
The weather warning is extended to the whole of the country from 9am tomorrow and will remain in place for some areas until the end of the weekend.
On Saturday as much as 50mm of rain could fall in an hour.
The Met Office has warned there is a chance “homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong wind”.
It added: “There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost.”
Temperatures so far this week have seen Brits sweltering in temperatures in the low 30s.
The Met Office has raised its heat alert level to three, urging people to protect themselves amid the “exceptionally hot weather forecast this week”.
Met Office meteorologist John Griffiths said there was even a chance the Welsh Marches – the area along the Welsh border – could see temperatures of 34C (93.2F) today.
The highest temperature ever recorded on a June day in the UK is 35.6C, which was set at Mayflower Park, Southampton in 1976.
However, when the thunderstorms strike the temperature will significantly drop.
According to NetWeather, on Saturday temperatures will peak at just 20C.
Similar temperatures are also expected for Sunday.
