hi there. for many, this weekend is going to be hot and humid again, especially for england and wales, with temperatures only slowly coming down across scotland and northern ireland. and as the cooler air starts to invade in there, we're likely to see increasing chance of thundery downpours, some of which could be quite heavy in places. certainly england and wales on sunday. now we've had some cloud drifting up from the south as we move into the early part of saturday, some mist and low cloud around some coasts of south—west england and wales. and it's here where we could see some showers or some thunderstorms, same too, across the north and the west of scotland. but elsewhere, it's a dry and a clear night.

and again, another very warm and muggy one to start saturday morning with temperatures no lower than around 18 or 19 in one or two spots. so it's a very warm start to saturday, pretty much from the word go. we'll have sunshine around, but well, this weather front will be pushing into the north west of scotland, bringing thicker cloud breeze, outbreaks of rain, a few showers elsewhere. and there will be some scattered thundery showers developing across england and wales as we see temperatures peak at around 32 or 33 degrees in the south—east. so this could be the hottest day of the heatwave. but these showers and thunderstorms, although well scattered, could be pretty intense if you catch one and there's a chance of some localised flooding as well. but most places will be dry to take us into saturday evening. we could see further clusters of showers and thunderstorms running up from the south. again, it's going to be a warm and a muggy night, especially so for england and wales with temperatures beginning to come down across the north—west.

now the great north run on sunday across north—east england looks pretty decent actually, although there will be some rain around. some of it could be thundery. these temperatures will be pretty comfortable for running in, but we could start off with some thundery rain in the morning and then into the afternoon. heavy showers could develop with a bit of sunshine in between. but sunday is another warm and humid one for england and wales, with a scattering of thunderstorms developing into the afternoon. temperatures again up to 30 degrees in the south—east, but you'll notice the low 20s for scotland and northern ireland. so things are turning cooler and the trend as we head into next week is for this cooler, fresher, less humid air to spread southwards across the country. and that'll introduce north—westerly winds and also plenty of showers, particularly in the north and the west. it'll be much cooler by day, much fresher at night, but still some good spells of sunshine across the south.
