Britain could be on course for another heatwave later this month, with fresh weather maps showing temperatures climbing above 30C in parts of the country just days after a projected cold snap. The latest WXCharts maps suggest a surge of hot air will begin pushing into southern Britain on June 17 before peaking on June 18. While the forecast is not currently as extreme as the record-breaking heat seen in May, temperatures could still reach 31C in parts of England.

The warmer spell follows a dramatic period of weather swings. Earlier forecasts indicated temperatures could plunge to just 1C in parts of Scotland on June 11, with much of the UK seeing overnight lows of between 5C and 8C. Even the normally warmer South East was forecast to struggle to reach double figures on the coldest day.

After that chilly interlude, weather maps show temperatures rebounding sharply, with parts of southern and eastern England turning red on forecasting charts as warmer continental air spreads across the country.

According to the June 18 temperature map, the hottest conditions are expected across East Anglia, the South East and parts of the East Midlands. The highest values on the map are concentrated around Greater London and South East, with temperatures up to 30C. According to the map, temperatures in those areas actually span a wider range, starting from as low as 18C along the Welsh coast and reaching up to 28C in the Midlands and South West, and 29C in the North East.

However, forecasters caution that the warmth may be short-lived. Previous charts have suggested temperatures could fall by nearly 10C within days of the peak, highlighting the highly changeable nature of June's weather.

The Met Office's long-range forecast for June 10 to June 19 states: "Changeable early in this period with Atlantic low pressure systems affecting the UK. These will bring showers or longer spells of rain at times. The wettest conditions will be in the northwest, with more in the way of drier interludes in the southeast.

"Strong winds may affect parts of the UK at times, especially the northwest. Later in the period, higher pressure and more settled conditions may begin to become more prevalent, especially in the south. There will probably still be some showers or longer spells of rain though. Temperatures are likely to be near to or a little above normal overall."
