00:00Hi there, Storm Dara at the weekend brought wind speeds in excess of 90mph in places and

00:07widespread damage as well as disruption. This week couldn't be more different. High pressure

00:11brings a prolonged settled spell, relatively quiet weather, although higher pressure doesn't

00:17always mean sunny skies. There will be some weather fronts brushing the far north and

00:21on the southern flank of the high as well. At least over the next few days there will

00:25also be some showery rain. This shows the total rainfall accumulations during the next

00:32few days, running from Monday up till Friday. And as you can see, showers building up across

00:37parts of southern England, Midlands as well as parts of East Wales during the next few

00:43days and then a sprinkling of showers across more central and north-eastern parts of the

00:48UK as we end the week. But for some places, the white colours indicating hardly any rain

00:54at all, northern and north-west Scotland, parts of Northern Ireland, western England

00:58and Wales for example. So we start off Tuesday with those drier parts of the UK, seeing clear

01:05skies and low temperatures. Tuesday begins with widespread minus figures across parts

01:12of Scotland and Northern Ireland and in some sheltered parts of Scotland as low as minus

01:165 to minus 10 Celsius. We'll also see some dense fog patches across parts of Northern

01:21Ireland into Scotland, especially through the central belt for example. And because

01:25the sun is weak at this time of year, the days are short and that fog could persist

01:30all day where it occurs and where that happens it's going to feel very cold. Further south,

01:36the cloud that we keep overnight keeps the fog away but it will be low cloud, so a gloomy

01:41day to come for the south and south-east. And further showers running in, especially

01:45across south-eastern England, particularly Kent, on a brisk north-easterly breeze. In

01:50that breeze it's going to feel on the cold side but temperatures in the south actually

01:55around average 7 or 8 Celsius. Whereas further north, especially where we keep the dense

01:59fog and the freezing fog in places, temperatures will remain significantly suppressed. And

02:04then fast forward to Wednesday morning and it's a similar start to the day. These are

02:08the overnight temperatures and you can see again widespread sub-zero temperatures for

02:13Scotland and Northern Ireland with dense fog patches first thing and in some places where

02:19the fog hasn't cleared that will just persist overnight and into the start of Wednesday.

02:23Some outbreaks of rain on Tuesday and into the start of Wednesday for the Northern Isles

02:27where it's a little milder with a lot of cloud cover. And likewise for much of England and

02:32Wales we keep the cloudy skies, although west Wales, parts of north-west England will start

02:36off clearer and colder first thing. Now there will be fewer showers across the south on

02:41Wednesday. In fact, for many parts of the UK it's dry. The rain in Shetland will tend

02:47to ease off as well. And skies will brighten a little across central parts where we see

02:52a lot of cloud through the next couple of days, some sunshine coming through. But the

02:56sunniest places will be away from the foggier parts of Scotland and Northern Ireland. Although

03:02once again, some fog will persist all day with light winds and weak sunshine across

03:08parts of Scotland, particularly again through the central belt where it will feel cold.

03:13Now heading into Thursday and a subtle change in the position of higher pressure will lead

03:19to some outbreaks of rain being drawn into more central parts of the UK, particularly

03:25around north-east England, south-east Scotland. Less rain further south and with more of a

03:31breeze coming into Northern Ireland I think we'll start off Thursday a little milder and

03:36with cloud rather than fog, although there will still be some fog patches across parts

03:39of Scotland. Scotland though, away from any fog patches, we'll see the sunniest skies

03:44on Thursday once again, central belt northwards, a brighter day to come for the Northern Isles

03:49for example. But around parts of Northern England into Norfolk, the North Midlands,

03:54North Wales, there'll be thicker cloud and some outbreaks of light, showery rain. A few

03:59showers coming into the far south-west on a brisk breeze, but otherwise mostly dry towards

04:04the south, but again with a lot of cloud cover. Now into Friday some changes start

04:10to take place and they originate over on the other side of the Atlantic. This cold air

04:15outbreak across North America will tend to amplify the jet stream so that we get this

04:20build of pressure on the other side of the Atlantic and that's going to push this weather

04:25front into north-western parts of the UK. It's also going to push higher pressure further

04:29east away from the UK. So all in all, Friday looks like a cloudier day for many places

04:35as this front comes south-eastwards into north-west Scotland and it will bring some showery rain

04:40particularly towards the end of the day. Best of any brightness first thing will be for

04:44the far north of Scotland, otherwise for many parts of the UK, Friday is a generally cloudy

04:48day. We've got the showery rain still across Northern England pushing north into parts

04:52of Scotland. Less fog around first thing because of the cloud cover, but it will be a relatively

04:56grey and gloomy day for many, temperatures of 4 to 6 degrees generally. And then we've

05:01got those showers pushing into north-west Scotland as we end the day and they'll tend

05:06to push south-eastwards as we go into the weekend. Although as that front runs into

05:11higher pressure it will tend to weaken and that means that the rain will tend to fizzle

05:17out as it pushes across Scotland, Northern Ireland and then into England and Wales later

05:21in the weekend. Meanwhile, the jet stream and the weather patterns upstream of the UK

05:28will become a bit more energised and that's going to make a return to more changeable

05:33weather, more rain and breezier conditions for the north-west as we go into Sunday. But

05:39higher pressure just about stays nearby across southern parts of the UK leading to mostly

05:45settled weather throughout the weekend in the south. We'll keep you updated as always

05:50on our YouTube channel, but for now that's all from me, bye bye.
