Turning Cooler & More Unsettled Everywhere This Weekend
By the weekend we will have lost the heat and humidity affecting southern areas, as a cold front introduces cooler and fresher conditions from the west, though it will turn increasingly unsettled too. For now, we have another dry, hot and sticky day in store for much of southern England, The Midlands and south Wales, with temperatures climbing to around 28C in Cardiff and 29C in London this afternoon. Cooling sea breezes should develop around coasts though, bringing onshore some coastal mist in places too. For north Wales, northern England and southern Scotland, generally a cloudy but humid day, with outbreaks of showery rain developing – which could turn heavy and thundery across north Wales and northern England. Northern Scotland should stay mainly dry and sunny today, though showery rain arriving this evening.
Another warm and sticky night for southern areas, scattered showers are likely across central and northeastern areas of England but otherwise a mainly dry night apart from showers across NW Scotland. Then for Friday, a more unsettled day, with sunny spells and showers in places, which may become heavy across SE England later, with a risk of thunderstorms too. So a risk of a downpour for the opening ceremony of the Olympics in London. SW England and Wales may escape with a dry day though. Still very warm and humid across southern areas, cooler and fresher further north.
Noticeably cooler and fresher over the weekend for all areas. Saturday probably the best day with much of England and Wales escaping with dry and sunny day, though showers developing towards western coasts. Scotland and Northern Ireland seeing a mixture of sunny spells and showers, heaviest and most frequent across the NW. Sunday looks like seeing a more widespread risk of heavy and thundery showers developing across the UK, with some sunny intervals in between. Temperatures generally reaching the mid to high teens at best over the weekend, though perhaps 20-21C in the SE.
Continuing unsettled through next week for most areas. More showers on Monday for many – some of which could be heavy and thundery. Then a spell of more persistent rain moving across southern UK on Tuesday, then a return to sunny spells and scattered heavy thundery showers affecting many areas for the rest of the week.
