00:00Hello, very good day to you. The heat wave is going to continue for a few days yet with

00:04some exceptionally hot weather around temperatures getting above 30 for some of us for several

00:09days now. The cause of it is our hot air that we have across us. It's dragged up from the

00:15south because we have high pressure to the east and low pressure to the west. And it's

00:19this high pressure in the east that's dominating the weather, leading to it being generally

00:23settled and plenty of clear sunny skies, hence why temperatures are rising so high. Take

00:28a look at the details through Thursday afternoon and you can see there are a few showers that

00:32have developed across parts of the southwest and southwest Wales as well. A little bit

00:36of uncertainty as to how much of the rain is actually going to reach the ground. There

00:40is a slice of drier air between the showers and the surface as a result. Some of those

00:45will evaporate before they reach us, but the potential for some downpours perhaps if these

00:49develop and if they actually make it to the surface. Otherwise, lots of dry sunny weather

00:55to be had, a bit more cloud than we've seen through some recent days, could be quite high

00:58level cloud though, so just turning the sunshine a bit milky, a bit hazy at times too. Look

01:03at those temperatures still well above average for the time of year, around 10 degrees above

01:06average for many of us, likely to get to highs around 31, 32 Celsius towards the southeastern.

01:12The heat is widespread even across far northern parts of Scotland. We could get into the mid

01:16to high 20s here. Through the end of the day, we're going to continue to see some showers

01:21across western parts in particular, perhaps some downpours then developing overnight across

01:25parts of Scotland. A good chance that some of these could perhaps be heavy and maybe

01:29thundery too. Clear skies for many as we go through the night though, like we've seen

01:33through some recent nights, some murkiness, some sea fog, low cloud drifting in from the

01:37North Sea affecting some eastern parts. Also, a few pockets of mist and fog developing elsewhere,

01:42but look at those temperatures still on the warm side. Another difficult night for sleeping,

01:47uncomfortable for some of us. It's going to be quite humid, quite muggy and temperatures

01:52in some towns and cities staying above 20 Celsius like we've seen through some recent

01:56nights. So a warm muggy start for many of us on Friday morning and a bit cloudy for

02:01some eastern parts. That cloud, that murk will gradually or quite quickly actually burn back

02:05towards the coast. And then yes, plenty of sunshine again for many parts. Still some

02:10high level cloud, particularly towards the south southwest. And then later on in the

02:14day, we will start to see the risk of some heavy thundery showers pushing in as we go

02:19into the evening. Temperatures may be a nudge down only by a degree or so compared to Thursday

02:25for some of us, but still a good chance that we'll get above 30 Celsius somewhere for the

02:29fifth day running. Through Friday evening, there's that risk of some thunderstorms perhaps

02:34affecting parts of Devon and Cornwall. A little bit of uncertainty about this though. Otherwise,

02:40generally staying dry with some clear skies. But once more, we are going to see some murkiness

02:44pushing in from the North Sea. Looking ahead to the weekend then and the hot weather is

02:49going to continue. Temperatures likely to reach highs of around 32, possibly 33 Celsius

02:54on Saturday and perhaps Sunday too. But with the hot weather, we do have the risk of some

02:58thunder. So things likely to take a bit of a breakdown as we go through the weekend and

03:03into next week when things should start to turn a bit more comfortable and cooler too.

03:07There's more information on all of that on our social media channels, our website and

03:11of course our app. See you later.
