Met Office warns of heatwave criteria

The Met Office has warned that temperatures in the South East could meet heatwave criteria by the weekend. By then, the West Midlands, parts of the West Country, and areas of Wales are also expected to experience warm temperatures in the mid-teens.

Jonathan Vautrey, a meteorologist at the Met Office, said: "By Friday there is potential for 30C across parts of south-eastern England." He added that rising temperatures and humidity will likely bring overcast skies for many.

Uncomfortable nights ahead

Mr Vautrey noted: "People will certainly be noticing how muggy it starts to feel during the second half of this weekend, and some quite uncomfortable nights for sleeping well, with overnight temperatures in the high teens across south-eastern areas of England."

In its forecast for Wednesday to Friday, the Met Office stated: "The weather remains mixed during the middle and second half of the week. There will be further rain, especially in the north and west. Some hot sunshine developing further southeast."

Regional temperature variations

Scotland and Northern Ireland are expected to see more cloudy weather and rain over the week, with temperatures unlikely to rise above 20C to 21C. The south of England, particularly, is set for hot summer weather with above-normal temperatures toward the end of June.

The Met Office forecast for June 20 to 29 reads: "There is the possibility of some very warm and humid weather across parts of south and southeast Britain at the start of this period and perhaps the chance of a few thunderstorms too. Generally more changeable to the north and west at first, but there is a signal for high pressure to build more widely as we move towards the latter part of June."
