The UK is preparing for another heatwave, with temperatures expected to rise back to 30°C in certain areas starting June 11. Following a brief drop to average temperatures, the Met Office forecasts that the mercury will climb again, particularly in the south-east around London. The Global Forecast System (GFS) weather model indicates that highs of 28°C could extend to regions as far north as Yorkshire by June 15, with similar temperatures anticipated on June 16. A total of 16 counties including Derbyshire, Nottinghamshire, and Kent are likely to experience these elevated temperatures. However, the Met Office also warns of possible thunderstorms and heavy rain as the month progresses. The forecast for late June suggests a shift towards more unsettled weather, with low pressure potentially influencing conditions, leading to increased chances of showers and storms. Overall, the Met Office highlights that the likelihood of hotter weather conditions through early August is significantly higher than cooler temperatures.
