If you haven't heard, the weekend's not looking too bad weather-wise,

0:00:020:00:05

but then into next week it stays on the unsettled side.

0:00:050:00:09

So let's take a look at a bit more detail.

0:00:090:00:11

Let's start with August so far, which has had normal rainfall,

0:00:110:00:14

actually, for Scotland and Northern Ireland.

0:00:140:00:16

However, for England and Wales we know it has been wet,

0:00:160:00:18

but it's been very wet across East Anglia

0:00:180:00:21

and the south-east in particular, where we've had, well,

0:00:210:00:23

during the course of Wednesday, just two or three inches of rain.

0:00:230:00:26

That's about the August rainfall in one day.

0:00:260:00:29

Now, those showers did eventually clear on Thursday,

0:00:290:00:31

most of us had dry, fine weather,

0:00:310:00:33

but already the change was afoot towards the north and west.

0:00:330:00:36

The next weather system is rolling in off the Atlantic.

0:00:360:00:38

That weather system looks set to bring rain to mostly western

0:00:380:00:41

and northern areas during the course of Friday, so eastern parts

0:00:410:00:44

may escape with a mostly dry, a second mostly dry day.

0:00:440:00:48

So, if you're up in the early hours of Friday morning,

0:00:480:00:50

you may be lucky enough to see the Perseid Meteor Shower,

0:00:500:00:53

because it's across England and Wales

0:00:530:00:54

where we'll have the clearest weather.

0:00:540:00:56

Friday night looks as if it'll be cloudier for the most part -

0:00:560:00:59

you may catch a glance in eastern parts of Scotland.

0:00:590:01:02

But as I say, it's a different-looking weather day.

0:01:020:01:04

It's windier, we could have gales in the north

0:01:040:01:06

and west blowing that rain eastwards across Scotland, Northern Ireland,

0:01:060:01:09

much of England and Wales except, perhaps, the East Midlands,

0:01:090:01:12

East Anglia and the south-east,

0:01:120:01:13

which is where it will feel warmest,

0:01:130:01:15

but for most of us it's much cloudier.

0:01:150:01:17

There won't be a huge amount of rain - it could be heavy

0:01:170:01:19

at times over the hills, but obviously it will feel cooler

0:01:190:01:22

because of the wind and the cloud and rain.

0:01:220:01:24

But as we move into Saturday,

0:01:240:01:26

the hope is that that north-westerly breeze will blow

0:01:260:01:28

a lot of the cloud away and so it will be an improving picture.

0:01:280:01:32

Not a particularly warm one,

0:01:320:01:33

just because we've got that breeze coming down from the north-west.

0:01:330:01:36

Not as strong winds either as Friday, but a cooler direction.

0:01:360:01:38

Eventually that rain clears away from southern and eastern areas.

0:01:380:01:41

So it's not a bad day, just a few showers around,

0:01:410:01:43

and then through Saturday night into Sunday

0:01:430:01:45

we see a little ridge of high pressure,

0:01:450:01:47

so again it will be quite chilly, I think, Sunday morning,

0:01:470:01:49

down into single figures in rural areas.

0:01:490:01:52

But it does look like the drier day of the weekend,

0:01:520:01:54

but both days don't look too bad.

0:01:540:01:56

Lighter winds, so feeling a little bit warmer,

0:01:560:01:58

and that high pressure should hold off these weather fronts

0:01:580:02:01

until later in the day.

0:02:010:02:02

They're more likely to come in through Sunday night into Monday.

0:02:020:02:05

You can see this little area of low pressure winding itself up,

0:02:050:02:07

another weather front to the north.

0:02:070:02:09

So we start the new week back to square one - pretty unsettled,

0:02:090:02:13

especially across the northern and western half of the UK,

0:02:130:02:16

central and eastern parts of England staying a little bit warmer

0:02:160:02:19

and sunnier and drier.

0:02:190:02:21

So, the rain again for the north and west on Monday,

0:02:210:02:23

but Monday evening and into Tuesday sees that rain and the emphasis

0:02:230:02:27

for the wetter weather shifting into eastern areas again.

0:02:270:02:30

And there could be a thundery element in that,

0:02:300:02:32

so again, Tuesday looks quite wet for a start.

0:02:320:02:35

There's some uncertainty on timings but we'll keep you posted.

0:02:350:02:37

And then behind that, it's sunny spells

0:02:370:02:39

and a scattering of showers, mostly in the north and west.

0:02:390:02:42

Now, once that area of low pressure moves away

0:02:420:02:45

there's a temporary ridge of high pressure,

0:02:450:02:47

so the middle of the week is set fair. But for how long?

0:02:470:02:50

Now, that's the question mark, because you can see

0:02:500:02:52

the succession of low pressures lining up in the Atlantic.

0:02:520:02:55

This one on Thursday, possibly Friday, looks particularly nasty.

0:02:550:02:58

But thereafter, we've got those weather fronts coming in.

0:02:580:03:01

And the difficulty is that with that area of low pressure

0:03:010:03:04

there may be some tropical air mixed in, which will give us

0:03:040:03:07

a lot of wet weather, but it also makes it more difficult

0:03:070:03:10

for the computer models to analyse it correctly.

0:03:100:03:13

So, yes, we have some uncertainty, but we know it will stay unsettled,

0:03:130:03:17

we're fairly confident about that, so there will be rain at times

0:03:170:03:20

and the potential is there for some stormy weather later in the week.

0:03:200:03:23

And again, no sign of any prolonged dry and sunny spells at this stage

0:03:230:03:26

but as ever, you can check the latest on the website.
