Hello. Since we had that run of a couple of named storms,

0:00:020:00:04

things have been quite quiet on the weather front,

0:00:040:00:06

but it's that time of year

0:00:060:00:08

and you wouldn't expect that spell of quiet weather

0:00:080:00:10

to last for any great length of time,

0:00:100:00:13

and a look at Friday's chart

0:00:130:00:14

shows there is signs of a change out towards

0:00:140:00:17

the west, but before that arrives,

0:00:170:00:19

we still have that quiet look to the weather,

0:00:190:00:22

and that tends to mean fog at this time of year.

0:00:220:00:25

It will be there again,

0:00:250:00:27

not necessarily where it's been in recent nights.

0:00:270:00:29

There is that risk for central and western parts particularly,

0:00:290:00:32

but as the day gets going,

0:00:320:00:34

there will be sunshine across western areas,

0:00:340:00:36

and a speckling of showers.

0:00:360:00:38

Not much more than that.

0:00:380:00:40

Some of you may even stay dry all day.

0:00:400:00:42

Just because we'll see more in the way of breeze

0:00:420:00:45

into Saturday, the fog risk is much reduced,

0:00:450:00:49

but we are going to replace it with another type of weather -

0:00:490:00:52

in the form of an active weather front.

0:00:520:00:54

Certainly for western parts on Saturday,

0:00:540:00:57

there could be quite a bit of rain

0:00:570:00:59

across Northern Ireland initially,

0:00:590:01:01

then swinging into western Scotland, Wales

0:01:010:01:03

and the western side of England.

0:01:030:01:05

Further east, not too much in the way of sunshine, I'm afraid.

0:01:050:01:08

At its thickest, the cloud, even away from that frontal system,

0:01:080:01:11

just generating the odd showery burst of rain.

0:01:110:01:14

That'll be the case getting up into the Northern Isles.

0:01:140:01:17

That same weather front

0:01:170:01:19

is making heavy weather

0:01:190:01:21

of getting further towards the east,

0:01:210:01:23

and it weakens all the while

0:01:230:01:24

as it runs into that area of high pressure,

0:01:240:01:27

so it'll be more of a band of cloud with the odd spot of rain,

0:01:270:01:30

not much more than that, come Sunday.

0:01:300:01:32

Towards the northwest,

0:01:320:01:33

a more active weather system

0:01:330:01:35

brings another spell of wet and windy weather,

0:01:350:01:37

initially into the northwest

0:01:370:01:39

but as we get on through Monday,

0:01:390:01:42

there is no escape.

0:01:420:01:43

You will at some point

0:01:430:01:45

see that spell of wet and windy weather

0:01:450:01:47

wherever you're spending the day.

0:01:470:01:49

There is some doubt at this range

0:01:490:01:51

as to how quickly that rain will get away

0:01:510:01:54

from the southeast.

0:01:540:01:55

No more the south and south-westerly breezes.

0:01:550:01:58

Once that front is through,

0:01:580:02:00

look where the wind is coming from.

0:02:000:02:02

Trace the isobars back

0:02:020:02:04

and they arc away towards the western side of Iceland

0:02:040:02:07

and up towards the Arctic.

0:02:070:02:09

There will be a different feel

0:02:090:02:11

to the days as we move out of Monday

0:02:110:02:14

through to Tuesday, Wednesday,

0:02:140:02:16

Thursday and perhaps as far ahead

0:02:160:02:17

as Friday,

0:02:170:02:19

so the early part of next week,

0:02:190:02:21

the mild air is away to the south of us,

0:02:210:02:23

we are very much on the cold side of the jet stream,

0:02:230:02:26

there'll be plenty of wind

0:02:260:02:28

and across the top two-thirds of the British Isles,

0:02:280:02:30

those showers will be wintry

0:02:300:02:32

and snow will begin to accumulate.

0:02:320:02:34

That regime will do us

0:02:340:02:35

from about late Monday

0:02:350:02:37

on through Tuesday, Wednesday,

0:02:370:02:39

Thursday and into Friday.

0:02:390:02:41

By the end of the week, we'll have

0:02:410:02:43

low pressure towards the northwest

0:02:430:02:45

but in the early part

0:02:450:02:46

of the weekend, it may well

0:02:460:02:48

slip away towards the near Continent

0:02:480:02:50

and that will allow a change in wind direction,

0:02:500:02:52

and that means a change in the shower distribution.

0:02:520:02:55

That is but a brief interlude.

0:02:550:02:57

Sunday and the first part of Monday

0:02:570:02:59

perhaps, it'll be quiet for a time

0:02:590:03:02

and then the low pressure goes

0:03:020:03:03

back to where we've seen it

0:03:030:03:05

for a few days - high pressure

0:03:050:03:07

well away towards the Azores -

0:03:070:03:09

but that does leave us again

0:03:090:03:11

with quite a noticeable flow

0:03:110:03:12

coming in from the west

0:03:120:03:14

or just north of west.

0:03:140:03:16

That's some way off.

0:03:160:03:18

The next week is going to be

0:03:180:03:19

often windy, really quite wintry

0:03:190:03:21

with those showers,

0:03:210:03:23

and there is just that chance

0:03:230:03:24

it'll turn colder for a time.

0:03:240:03:26

Wherever you are, take care.

0:03:260:03:27

Bye-bye.
