Weather models show that temperatures in Britain could exceed 30 degrees later this month. The maps indicate another heatwave, with temperatures set to stay above the official heatwave threshold for three days. The weather shift comes after a wet and gloomy start to the month. The hot spell in May ended abruptly last week. But meteorologists at the Met Office have said the likelihood of further heatwaves in the coming months is increasing. The GFS weather model shows temperatures starting to rise from June 17, with pleasant highs of 28°C in the southeast, 27°C in East Anglia, 26°C in the northwest and the Midlands, and 24°C in Wales. Scotland and Northern Ireland should be somewhat cooler. The maps show that on June 18, temperatures could reach the 30°C mark in the southeast, with 29°C even as far north as Yorkshire. Parts of Northern Ireland could even reach 26°C, while Wales is also firmly in the mid to high 20s. The warmest conditions are expected on June 19. The GFS model shows highs of 30°C or more across much of England, possibly even 27°C in parts of southern Scotland. Southeast England is expected to be the hottest region, with a possible 32°C. Overall, the data shows that 13 counties could see highs of 31°C or more on June 19. If the data from this GFS model run were to materialize, it would mean another official heatwave in at least some parts of the country. An official heatwave is declared when temperatures exceed the heatwave threshold for three consecutive days. The heatwave threshold varies from 25°C to 28°C in different counties. It is 28°C in the southeast and drops to 25°C the further you move away from the southeast. These GFS model data show highs of 28°C, 30°C, and then 32°C in the same areas from June 17 to 19 – that would be an official heatwave. The latest Met Office forecast for the second half of the month suggests that southern regions could soon face “hot” conditions. However, “thunderstorms” are also possible.
