Sunday will bring a mixture of sunshine and showers across northern Britain, with largely dry conditions to close out the weekend in the south. Into the start of next week, low pressure is most likely to be close to northwest Britain, bringing stronger winds and occasionally heavy rain. Further southeast, it should be mostly dry with the potential to tap into very warm air drifting north out of Europe. Towards midweek, the wetter and somewhat cooler weather in the northwest looks to push further southeast, displacing the warmth and sunshine here. By the end of the month, a more widely changeable pattern looks most likely, with the wettest weather most likely further to the northwest, and sunshine more prevalent in the southeast.

As we move into August, the final month of the meteorological summer, confidence is low in the forecast with no one single weather pattern looking to dominate. As is often the case in summer, this could well mean plenty of fine, dry weather, interspersed with occasional thundery outbreaks, leading to marked local variations in rainfall. Temperatures are likely to pan out above average, perhaps more especially in the south and west.
