UK Weather Outlook: Hot Spells, Rainy Interludes and Uncertain September

A brief spell of hot weather is expected across southern England, with highs around or just above 30°C, while Scotland and Northern Ireland face a wet, windy Saturday and a rain band moving southeast on Sunday. The following days should be mostly dry and warm, though isolated showers may appear in western and northern Scotland. From mid-August onward, Atlantic low-pressure systems are likely to increase the chance of rain and thunderstorms, particularly in northern regions, while temperatures stay above average.

By the end of the month, high pressure may dominate again, bringing warmer conditions, though some models suggest a possible shift that could allow cooler, wetter weather. Forecast confidence for early September remains low, with divergent scenarios ranging from continued warmth to a return of unsettled conditions.
