Hello, thanks for joining me.

0:00:020:00:03

We'll be giving you a fair amount of detail

0:00:030:00:05

on how we expect to see the weather developing

0:00:050:00:07

right across the British Isles over the next few days,

0:00:070:00:09

and that will take us through the weekend

0:00:090:00:10

and into the first part of next week.

0:00:100:00:12

Then we'll try and give you some themes

0:00:120:00:14

about what happens next week.

0:00:140:00:15

In the shorter term,

0:00:150:00:16

fairly quiet spell of weather at the moment,

0:00:160:00:18

a little weak ridge of high pressure, there,

0:00:180:00:20

following in behind an old weather front

0:00:200:00:22

that was all over the eastern side

0:00:220:00:24

of the British Isles on Wednesday,

0:00:240:00:25

still producing enough cloud

0:00:250:00:27

for the odd bit and piece of rain, here.

0:00:270:00:28

The main story, first up, though,

0:00:280:00:30

across many western areas is one of fog,

0:00:300:00:32

and some of that fog

0:00:320:00:33

may well linger on through the day -

0:00:330:00:35

but, if you manage to get rid of that,

0:00:350:00:37

it is in the west

0:00:370:00:38

that you're more likely to see

0:00:380:00:39

the better chance of sunshine.

0:00:390:00:40

Temperatures, though,

0:00:400:00:41

not really responding to that -

0:00:410:00:43

particularly where you hold on to the fog

0:00:430:00:44

you could be down 2, 3, 4 degrees

0:00:440:00:46

either in the west or in the east,

0:00:460:00:48

close by to that old front.

0:00:480:00:50

That old front,

0:00:500:00:51

there's still enough about it

0:00:510:00:52

still to be producing the odd spot of drizzle

0:00:520:00:54

as we get on through Thursday night

0:00:540:00:56

into the first part of Friday.

0:00:560:00:58

Out towards the west, again,

0:00:580:00:59

it's a combination of pretty chilly fare

0:00:590:01:02

and that prospect of some fog, as well.

0:01:020:01:05

Those quiet conditions look set to stay on

0:01:050:01:08

into the first part of Friday, certainly,

0:01:080:01:10

although we'll begin to see

0:01:100:01:11

something of a change moving in

0:01:110:01:13

towards the west as, initially,

0:01:130:01:15

it's the breeze that picks up,

0:01:150:01:16

so, I don't think Northern Ireland

0:01:160:01:18

will see much of a problem with fog

0:01:180:01:19

on Friday morning.

0:01:190:01:20

It could still be an issue for other parts,

0:01:200:01:23

but, again, it's a cloudy day,

0:01:230:01:24

the odd spot of rain,

0:01:240:01:26

where the cloud thickens up

0:01:260:01:27

for any length of time.

0:01:270:01:28

Hints of brightness, yes,

0:01:280:01:30

but that's for the favoured few

0:01:300:01:32

rather than for the many.

0:01:320:01:34

Even on into the weekend,

0:01:340:01:35

this area of low pressure

0:01:350:01:37

is trying to throw that frontal system

0:01:370:01:39

in towards British Isles,

0:01:390:01:40

but making heavy weather of it,

0:01:400:01:41

if you'll forgive the pun,

0:01:410:01:43

simply because it's running into the high pressure

0:01:430:01:45

dominant over Europe.

0:01:450:01:46

So, the front, if you happen to get it,

0:01:460:01:48

stays with you for the greater part of the day,

0:01:480:01:50

and that means many western parts,

0:01:500:01:52

and especially through Northern Ireland,

0:01:520:01:54

and here we are, as far ahead as Sunday,

0:01:540:01:56

and that weather front rather dying a death.

0:01:560:01:58

Here, you'll have to join the dots

0:01:580:01:59

through central and eastern parts.

0:01:590:02:01

That's the remnants of that front.

0:02:010:02:02

Something a good deal more active

0:02:020:02:04

coming in from the Atlantic

0:02:040:02:05

producing very much more wet and very much more windy weather -

0:02:050:02:09

and here comes that weather front.

0:02:090:02:11

Gradually, we suspect, at this range -

0:02:110:02:13

and it is a suspicion -

0:02:130:02:14

working its way across the British Isles.

0:02:140:02:17

I think that's fairly well nailed on,

0:02:170:02:19

but my suspicions are raised

0:02:190:02:20

about just how quickly it's going to get away

0:02:200:02:22

from the eastern side of the British Isles.

0:02:220:02:24

Following on behind,

0:02:240:02:25

there are brighter skies,

0:02:250:02:26

but, my word, I think the temperatures

0:02:260:02:28

are going to begin to dip away,

0:02:280:02:30

and that's because we will find ourselves

0:02:300:02:32

in the first part of next week

0:02:320:02:34

on the cold side of the jet stream.

0:02:340:02:37

You'll see that there is mild air to be had,

0:02:370:02:39

but, my word, it's away, away down

0:02:390:02:41

towards the south-west of the British Isles,

0:02:410:02:44

and the contrast is such

0:02:440:02:45

between the colder air to the north

0:02:450:02:46

and the milder air to the south

0:02:460:02:48

that there will be a lot of wind generated,

0:02:480:02:49

and there will be westerlies,

0:02:490:02:51

and they'll rattle in a number of showers.

0:02:510:02:53

Some of those really quite squally, thundery,

0:02:530:02:55

and they'll be snowy on the higher ground.

0:02:550:02:57

As we move towards the end of the week,

0:02:570:02:58

so the low pressure moves its station

0:02:580:03:01

from the north-west of us out towards the east,

0:03:010:03:03

high pressure builds out towards the west,

0:03:030:03:05

and that generates

0:03:050:03:06

something of a north to north-westerly wind

0:03:060:03:09

down and across all parts of the British Isles.

0:03:090:03:11

Now, that orientation

0:03:110:03:13

is pretty short-lived.

0:03:130:03:14

I think what we have to work on

0:03:140:03:15

for the greater part of that week

0:03:150:03:17

is that it'll be often windy,

0:03:170:03:18

really quite wintry, those showers,

0:03:180:03:20

across the northern half of the British Isles,

0:03:200:03:22

and then, with that change in orientation

0:03:220:03:23

to the north,

0:03:230:03:24

a bit of a short, sharp shock

0:03:240:03:26

of colder weather to many parts.

0:03:260:03:28
