Advanced weather modeling indicates that the UK is on the brink of experiencing its hottest day ever, with another heatwave looming on the horizon. Record-breaking temperatures exceeding 37C were recorded this week, marking the hottest June days in history consecutively, culminating in a peak of 37.3C on Friday.
The latest data from the GFS weather model suggests that the UK may soon witness the highest temperature ever recorded in British history, surpassing the current record of 40.3C set during the scorching July 2022 heatwave. The upcoming heatwave is expected to grip the country starting on July 8, with temperatures potentially soaring to 35C in the south-east and reaching as high as 33C in regions as far north as Yorkshire.
As the heatwave progresses, temperatures are projected to escalate further, with southern England potentially experiencing highs of 37C on July 9. The mercury could climb to 32C in parts of South Wales as well. July 10 may see unprecedented highs of 40C in western and southern England, with central and southern regions likely to see temperatures ranging from 37C to 39C, potentially making it the hottest day on record.
July 11 is anticipated to be even warmer, with western England possibly hitting 41C and other areas like Yorkshire to London reaching up to 40C. Subsequent days are predicted to maintain high temperatures, with maximum highs of 38C in the south-east on July 12 and around 37C on July 13.
These soaring temperatures are likely to trigger an official heatwave declaration as temperatures are expected to surpass the heatwave threshold for three consecutive days. The UK will be covered in areas of deep red and black on temperature anomaly maps, indicating temperatures well above the seasonal average.
According to the GFS weather model, 18 counties in England could reach temperatures of 40C or higher. The Met Office has hinted at the possibility of more hot weather in the coming months, with the likelihood of thundery showers as well.
Looking ahead to the period from July 12 to 26, the Met Office forecast suggests a higher chance of settled and dry conditions due to high pressure systems dominating. However, outbreaks of rain and thunderstorms may occur intermittently, especially in the northern regions. Despite some variability, temperatures are expected to remain above normal, with occasional hot conditions.
