00:00Blue skies and high temperatures throughout the week ahead.

00:04Temperatures could be reaching the highest

00:06we've seen so far this year in some locations.

00:09The satellite image does show a big area of low pressure

00:12out to the west, a swirl of cloud here,

00:14but it's mostly just staying out here.

00:17We do have an arm of it that's been pushing

00:19across the southwest first thing this morning,

00:22producing one or two scattered showers

00:24and still producing a few across the Republic of Ireland.

00:27But they're tending to drift away

00:28and high pressure is firmly in control.

00:31Still a bit breezy on some eastern coasts

00:33down across southwest England and southwest Wales,

00:36but the breeze here easing further through the afternoon.

00:39Little misty across northern parts of Scotland

00:41and some mist and low cloud,

00:43just threatening to edge in at times from the North Sea.

00:46But for most places, it is a sunny day

00:49and a very warm day.

00:51Temperatures significantly above average

00:52for the time of year 30, 31, perhaps in the London area,

00:56maybe even a degree or so higher.

00:57A little cooler on some coasts,

00:59particularly if that mist sticks around

01:01and with a bit of a breeze,

01:03but generally temperatures, as I say,

01:05into the mid to high 20s and above average

01:08for this time of September.

01:09It's going to be a very warm evening,

01:11a balmy evening, if you like.

01:13Overnight, we will see encroachment

01:15of this mist and low cloud,

01:18just pushing into parts of northeast England,

01:20maybe even as far south as the Midlands

01:22and much of eastern and northern Scotland.

01:24So it'll be a grey, murky start here

01:26to Wednesday morning everywhere.

01:27It's going to be a warm night,

01:29an uncomfortable night for sleeping.

01:30Temperatures across Scotland may dip down

01:33into the low teens or touch lower in some rural locations,

01:37but certainly across the south, high teens in urban areas,

01:40some spots may not dip below 20 Celsius.

01:43So again, very warm for the time of year,

01:46an uncomfortable and difficult night for sleeping.

01:49Through Wednesday morning, as I mentioned,

01:50a bit of a drab start for eastern Scotland,

01:53northeast England, down into the Midlands,

01:55a lot of mist and low cloud,

01:56even some around the coast further west.

01:58During the day, the mist and low cloud inland

02:00should retreat back to the coast.

02:02Some of those North Sea coast may just stay a little hazy,

02:05even into the afternoon.

02:07If it does, temperatures will not perhaps get as high,

02:10but certainly for many inland areas,

02:13hot day on Wednesday, widely into the mid-20s,

02:17more widely over central and eastern parts of England,

02:19over 30 Celsius, could reach 32 in and around London

02:23during Wednesday afternoon.

02:26Further west, again, a little cooler around some coasts,

02:28but generally still significantly above average

02:30for the time of year.

02:31So this hot spell continues,

02:33and particularly on Wednesday night,

02:35a very warm and sticky night.

02:37But introducing a bit more moisture,

02:39just notice there are some areas

02:41where there's the threat of some heavy

02:43and thundery showers developing.

02:45That's something to keep an eye on

02:46as we head into Thursday morning.

02:48But again, those temperatures will be pretty warm,

02:50a difficult night again for sleeping,

02:52and more widely in the south,

02:54temperatures in the high teens are perhaps a few spots,

02:55again, staying over 20 degrees Celsius.

02:58That's pretty unusual for September,

03:00particularly to have back-to-back nights above 20 Celsius.

03:04High pressure continues to dominate,

03:06although it is sitting to the east.

03:07There's that low down to the southwest,

03:08but at the same time, low pressure systems

03:10just moving in from the north,

03:12introducing perhaps a bit more cloud at times here,

03:15and generally introducing more moisture.

03:16So as we head into the weekend,

03:17yes, most places are gonna stay very warm, dry, and sunny,

03:20but there is an increasing chance

03:22of seeing some thundery showers.

03:24The warm air is still in place

03:25because we've got the high here

03:27wafting up the warm air from the south.

03:29But this little weather front's introducing

03:30the threat of some thundery showers

03:33heading north during Wednesday night and into Thursday.

03:36And then as we head towards the weekend,

03:38the cooler air is up here,

03:39but it is just threatening to push further south,

03:42not really likely to arrive until early next week.

03:46So the warm spell will continue,

03:47but as we head towards the weekend,

03:49an increasing chance of seeing

03:50some thundery showers breaking out.

03:53We'll keep you updated on more of that, of course,

03:55and the best way to stay up to date yourself

03:57is to follow us on social media.
