The UK is bracing for a significant drop in temperatures, with forecasts indicating lows of 4C in various regions, particularly in Scotland. Following a record heat wave that brought the hottest May day on record, the weather is set to cool dramatically around June 17. Areas such as Inverness, Angus, and Perthshire will experience the coldest conditions, while other regions in England and Northern Ireland will also see temperatures dip below 10C. This sudden change follows a period of high temperatures, with some areas reaching 29C just before the drop. The Met Office has noted that while the weather will be relatively settled with high pressure bringing dry conditions, there may be showers in certain areas. As June progresses, there is potential for temperatures to rise again, particularly in southern regions, reminiscent of the heat wave experienced earlier in the month.
