And looking even further ahead – Thursday 31 Jul - Thursday 14 Aug – ‘The rather changeable pattern will likely continue through early August with spells of rain or showers mixed in with some drier, brighter days. ‘Towards mid-August, there are tentative signs that high pressure may become rather more dominant, which could bring more in the way dry, settled weather more widely. ‘Temperatures will likely continue to be above average overall, with the possibility of very warm or hot spells developing later in the period, especially further south and east.’
