Hello. If the cold weather has not been your thing

0:00:030:00:05

well, the good news is we've lost that chilly easterly component

0:00:050:00:07

to our wind from the rest of this week.

0:00:070:00:09

Air is coming off the Atlantic,

0:00:090:00:10

which means milder weather for all compared to what we've been used to.

0:00:100:00:13

But, of course, coming off the Atlantic, we do see a bit more cloud

0:00:130:00:16

and there will be a bit of rain rather than snow at times.

0:00:160:00:18

At the moment, we've got high pressure.

0:00:180:00:20

That, through the last 24 hours, has been drifting its way southwards,

0:00:200:00:23

and so the easterly winds have pushed off

0:00:230:00:25

down in towards south-west Europe.

0:00:250:00:26

We've got the Atlantic air but, through Wednesday, outbreaks of rain

0:00:260:00:30

comes with cloud across Scotland, Northern Ireland

0:00:300:00:33

and, late in the day, far north of England and North Wales.

0:00:330:00:35

Not a thoroughly soggy day, still some breaks to the east of Scotland.

0:00:350:00:38

Could hit around 12 or 13 here.

0:00:380:00:40

Across England and Wales, most places will stay dry.

0:00:400:00:43

Sunniest in the morning, widespread frost.

0:00:430:00:45

7-10 degrees by the afternoon.

0:00:450:00:48

Through the evening, that thicker cloud will gradually work its way

0:00:480:00:51

across England and Wales, producing the odd spot

0:00:510:00:53

of light rain or drizzle,

0:00:530:00:54

but those winds coming off the Atlantic.

0:00:540:00:56

If we look out to the Atlantic and the jet stream,

0:00:560:00:58

it's got this undulating pattern,

0:00:580:01:00

which means that weather gets a bit more changeable

0:01:000:01:02

through the rest of the week.

0:01:020:01:04

The big lump you can see there, though, into Thursday is a ridge

0:01:040:01:06

of high pressure bringing up some milder air for all by this stage,

0:01:060:01:09

ahead of an approaching weather front.

0:01:090:01:12

So after some overnight cloud and patchy rain,

0:01:120:01:14

some breaks in the cloud boost the temperatures quite nicely.

0:01:140:01:17

Strong to maybe gale force winds later on across the west.

0:01:170:01:20

Outbreaks of rain Northern Ireland, Western Scotland and,

0:01:200:01:23

by the time we hit the end of the afternoon, in the far west of Wales.

0:01:230:01:26

But with some hazy sunshine still in the eastern areas,

0:01:260:01:28

12-14 degrees is certainly possible.

0:01:280:01:31

We stay mild as we go through the night and into Friday.

0:01:310:01:34

Outbreaks of rain pushing across most areas,

0:01:340:01:37

but this little wraparound of an occlusion close to the centre

0:01:370:01:40

of low pressure will feed in quite a wet day

0:01:400:01:42

on Friday, it looks like, in Northern Ireland.

0:01:420:01:44

Parts of west of Scotland as well.

0:01:440:01:45

Maybe a little bit of snow over the hills,

0:01:450:01:47

but for most it's rain.

0:01:470:01:49

Come away from that, it's a day of sunshine and showers on Friday.

0:01:490:01:52

Some showers heavy with hail and thunder, big gaps in between,

0:01:520:01:56

and there will be some, particularly in the eastern areas,

0:01:560:01:58

who will stay dry all day long.

0:01:580:02:00

Temperatures still getting to double figures for some.

0:02:000:02:02

Little bit cooler, admittedly, as we finish the week

0:02:020:02:04

going into the weekend, as we'll see on Wednesday and Thursday.

0:02:040:02:07

Low pressure, though, pushing further north.

0:02:070:02:09

That means showers will be migrating with it,

0:02:090:02:11

mainly across Scotland, Northern Ireland and northern England.

0:02:110:02:14

Occasional showers, heavy with hail and thunder. Maybe a bit of sleet

0:02:140:02:17

over very high ground, but for most it's rain.

0:02:170:02:19

Head further south, well, a slight ridge of high pressure builds in.

0:02:190:02:22

Morning patchy mist and fog, maybe one or two showers.

0:02:220:02:25

But most places will actually be dry

0:02:250:02:27

and having a pretty decent weekend across southern areas.

0:02:270:02:29

We could see a weather system very close to the south-west into Sunday.

0:02:290:02:32

The emphasis is on that pushing towards western France

0:02:320:02:35

instead of our shores.

0:02:350:02:36

So still at the moment, much of England and Wales,

0:02:360:02:39

bar one or two isolated showers,

0:02:390:02:40

morning mist and fog clears, sunny spells, many will be dry.

0:02:400:02:44

A few showers continue in Scotland and Northern Ireland.

0:02:440:02:46

It's here where the breeze will still be a feature,

0:02:460:02:49

but not a cold weekend, with temperatures still 10-13 degrees.

0:02:490:02:53

Into next week, after this ridge of high pressure

0:02:530:02:56

caused by the jet stream,

0:02:560:02:58

the jet stream starts to charge a little bit more across.

0:02:580:03:00

It's putting its back into more changeable conditions

0:03:000:03:03

through much of the week.

0:03:030:03:04

That means low pressure a bit more dominant,

0:03:040:03:06

particularly to the north of the UK.

0:03:060:03:08

This is where it'll always be windier and, at times, wetter.

0:03:080:03:10

But it's by no means a wash-out of a week.

0:03:100:03:12

Still some drier, sunnier days. Compared to what we've had of late,

0:03:120:03:15

mild overall. But there are a few hints as we head towards Easter,

0:03:150:03:18

as low pressure pushes towards the east of us,

0:03:180:03:21

we could drag in some colder air.

0:03:210:03:22

Not the bitter easterly winds we've had, but temperatures dropping

0:03:220:03:25

relative to what we'll see through the week. We'll keep you updated.
