drawing a hot Tropical Continental Airmass; this type of pressure pattern being typical of heatwave conditions across the UK. Temperatures on the 9th reached 31 to 32°C fairly widely across south-east England, and 33°C in London. As often happens in the UK, the heat and humidity lead to some intense

from the southwest will keep temperatures on the mild side, with little sign of any significant cold spells. Ensemble forecasts for London suggest average temperatures of 10–11°C, with only brief dips into colder territory. Even in Edinburgh, the pattern is similar, with only short-lived colder snaps
