00:00Hello, and welcome to the Met Office forecast for the week ahead. The UK heatwave continues

00:05through the rest of the week, sunny and hot in many places, unusually hot for some, especially

00:11Wednesday, Thursday, towards the west of the UK. More on that in a moment. Not only will

00:17we have the high temperatures by day, but we'll also experience very warm nights, uncomfortable

00:22for sleeping. And that means that Tuesday gets off to a warm start, temperatures quickly

00:26rising, hot and sunny for many of us once again. One exception, north-east Scotland

00:30where we keep some low cloud around coastal areas in particular, that will keep things

00:34cooler here. Otherwise, those widespread high temperatures could spark the odd thunderstorm,

00:39especially towards the south-east. These will be very isolated, however, for the vast majority

00:45it's staying very warm or hot and sunny. Temperatures in the south, again, 30 to 32 Celsius possible

00:51somewhere around the midlands, south Wales into the south-east of England. But those

00:55temperatures are rising further north-west as well. Northern Ireland, south-west Scotland,

00:58north-west England, high 20s. You'll notice the significant difference towards the north-east

01:02of Scotland, mid to high teens here. And we're going to see that low cloud continue to affect

01:07parts of eastern Scotland and northern Scotland through Wednesday morning. Again, an uncomfortable

01:12night for sleeping and a warm start to the day on Wednesday. And that heat, once more,

01:17as it builds into the afternoon, could trigger a torrential shower or thunderstorm. You'd

01:22be unlucky to be caught in these. They will be very isolated, but I think where they do

01:26occur could be some impacts because of the torrential nature of these thunderstorms.

01:32Nevertheless, where we've got the sunny skies, it will be another very warm or hot day. We

01:38do it all again on Thursday, some of that low cloud affecting North Sea coast and some

01:43of that heat triggering thunderstorms or torrential showers. But otherwise, for many, it's simply

01:49a sunny Thursday with, again, very high temperatures. And the temperatures increasingly a talking

01:56point, I think, through Wednesday and Thursday in some places.

01:59Now, at the start of this week, Monday, Tuesday, the heat across the UK is concentrated across

02:04southern parts of the country. But some changes mid-week. This low pressure will approach.

02:10That's going to bump up against the high pressure that's keeping things sunny for the UK. And

02:15as they squeeze together, the heat in the south will move northwestwards and that will

02:20turn things unusually hot for western parts of the country. Now, the likes of London and

02:25Birmingham are used to temperatures at around 30, 31, 32 Celsius. That's not necessarily

02:31the case for parts of southwest Scotland, Northern Ireland and western parts of Wales

02:36and the southwest of England. So as far as anomalously high temperatures, unusual temperatures

02:41are concerned, the greatest threat is on Wednesday and Thursday for western parts

02:47of the country. And I say threat because although for many places, many people, it's the kind

02:53of weather that you might enjoy in the summer. But this kind of weather does impact vulnerable

02:58people, especially given that the temperatures aren't falling much at night and then they're

03:02rising to those unusual values in places by day.

03:06So let's take a look at what the temperatures will mean for Thursday. Again, low 30s for

03:11southern parts of England and Wales, but you'll notice we're up to 30 Celsius, perhaps

03:15for west Wales, but more especially northwest England, the coast of southwest Scotland as

03:19well as Northern Ireland and southwest England. And those temperatures continue to rise on

03:25Thursday. And that means that although it will be cooler for some southern and eastern

03:30coasts, inland temperatures again exceeding 30 Celsius widely, north coast of Devon, for

03:35example, into much of central and western England and for the likes of west Midlands,

03:41south Wales as well, 30 to 33 Celsius possible. So again, unusually high temperatures could

03:47have some impacts on vulnerable people, especially given they're not cooling off much at night.

03:52And for northwest England for Thursday into southwest Scotland, Northern Ireland, high

03:5620s, 30, perhaps even a little higher in one or two spots. And that Northern Ireland temperature

04:02record not too far from those temperatures that you see on the map. So that's certainly

04:07one to watch. And Northern Ireland seeing the greatest temperature anomaly by this stage.

04:13So the greatest difference compared to their average for the time of year. A big contrast

04:17across Scotland, much cooler to the northeast and much warmer towards the southwest. High

04:23pressure holds on on Thursday into Friday for many places. But the low pressure I mentioned

04:27towards the southwest, well, that's likely to bring a change by Wednesday. Not initially.

04:32Initially, it will be warm or very warm and sunny in many places. I think a bit more of

04:37this North Sea low cloud affecting eastern areas. So a much cooler day to come here.

04:42But elsewhere, plenty more of that very warm sunshine to come. Perhaps temperatures not

04:46quite as high as they were on Wednesday and Thursday. But nevertheless, high 20s, the

04:50odd 30 possible. And then towards the southwest by the end of Friday, signs of that change

04:55coming along with some thunderstorms or heavy rain arriving later on. That then moves its

05:01way northwards during Saturday and slows down. So it's really the southern half of the UK

05:07where things turn a bit more unsettled for the start of the weekend with the risk of

05:11rain or showers or thunderstorms. Scotland, Northern England, Northern Ireland keep the

05:15sunshine on Saturday and the high temperatures. And in fact, whilst much of the country is

05:20beginning to cool down, northwest Scotland is beginning to warm up as the heat pushes

05:27northwards here. And then by Sunday, for many places, it's back to rain or showers. But

05:32northwest Scotland in particular may hang on to the heat and the sunshine for another

05:39day. Follow us on social media and we'll keep you updated on these channels. Bye bye.
