This will lead to more settled, warm or very warm conditions for many, especially across England and Wales, though some rain may still affect the far north.Article continues below"The forecast for this weekend suggests that temperatures could approach high 20C across parts of England, perhaps 30C in parts of the southeast, with values of mid to high 20C in Wales."Although a return to heatwave conditions is looking increasingly likely for some areas, the likelihood of such extreme high temperatures or high levels of humidity as last week is currently low."According to the Met Office, yellow alerts may be issued during periods of heat which would be unlikely to impact most people, but those who are particularly vulnerable, such as the elderly with multiple health conditions and on multiple medications.Choose Daily Mirror as a 'Preferred Source' on Google News for quick access to the news you value.‌Breaking NewsWeather
