The UK is bracing for a three-day heatwave beginning June 17, with forecasts indicating temperatures could soar to 31°C across various regions. The Met Office has reported an increased likelihood of heatwaves following last month’s record high of 35.1°C, the hottest May temperature ever recorded. The GFS weather model predicts pleasant highs of 28°C in the south-east, 27°C in East Anglia, and 26°C in the north-west. By June 18, temperatures are expected to reach 30°C in the south-east and 29°C in Yorkshire, with Northern Ireland potentially hitting 26°C. The peak of the heatwave is anticipated on June 19, with 32°C possible in the south-east and 13 counties across England projected to experience highs of 31°C or more. An official heatwave is confirmed when temperatures exceed the local threshold for three consecutive days, which varies from 25°C to 28°C depending on the region. Following the heatwave, the Met Office has indicated that thunderstorms may develop, particularly in southern areas, as low pressure begins to influence the weather towards the end of June.
