Spring is just around the corner,

0:00:020:00:03

but when I say that, I mean meteorological spring,

0:00:030:00:07

which starts on March 1st,

0:00:070:00:10

so we've just got a few days of "winter" left.

0:00:100:00:14

And how's it looking?

0:00:140:00:15

Well, this weekend, relatively mild but very changeable.

0:00:150:00:18

But then into March, things will cool off a little bit

0:00:180:00:21

and the weather will remain very, very changeable.

0:00:210:00:24

So as far as Saturday and Sunday's concerned,

0:00:240:00:27

we'll see weather fronts pushing through the UK.

0:00:270:00:30

Here's a look at Saturday.

0:00:300:00:31

Fronts moving through, extensive cloud,

0:00:310:00:33

outbreaks of rain - most of the rain

0:00:330:00:35

will be across western areas of the UK,

0:00:350:00:37

and the wind's going to be picking up as well.

0:00:370:00:39

But these are mild southwesterlies, so we're talking about temperatures

0:00:390:00:43

into double figures across most of the UK.

0:00:430:00:45

And the most amount of rainfall is expected to fall

0:00:450:00:47

across the north-west of England, so Cumbria, Lancashire,

0:00:470:00:50

places like that. The rain will wax and wane through the weekend,

0:00:500:00:53

particularly in between weather fronts it'll dry out,

0:00:530:00:56

but I think overall it's this portion of the UK here

0:00:560:01:00

that will be getting most of the rainfall.

0:01:000:01:01

So I think a fairly chilly start to Sunday, and dry,

0:01:010:01:05

with some sunshine across many central, eastern and southern areas,

0:01:050:01:09

but very quickly, linked to this low pressure here,

0:01:090:01:12

weather fronts will come zooming in.

0:01:120:01:14

So increasing winds, even gale-force winds a little bit later on,

0:01:140:01:17

particularly around these southwestern approaches

0:01:170:01:20

around the Welsh coast. Irish Sea very windy

0:01:200:01:22

on the coastline, on the hills, and we've got those outbreaks of rain.

0:01:220:01:25

So the heaviest of the rain again across these north-western areas

0:01:250:01:29

whereas the further east you are on Sunday

0:01:290:01:31

and the further south you are on Sunday,

0:01:310:01:33

the better the weather will be.

0:01:330:01:35

So a very breezy Sunday, looks like it's going to be

0:01:350:01:38

a very breezy and changeable Monday as well.

0:01:380:01:40

With low pressure sitting on top of us, a very unsettled day.

0:01:400:01:43

I think it's going to be one of those days where you have

0:01:430:01:46

bright sunshine and dark cloud,

0:01:460:01:48

maybe some thunder and lightning - all sorts.

0:01:480:01:51

So quite a dramatic day, I think,

0:01:510:01:52

as far as the look of the sky is concerned.

0:01:520:01:54

We'll see scenes like this

0:01:540:01:56

and then we'll see some rainbows, a crack of thunder,

0:01:560:01:58

and perhaps even some hail at times as well.

0:01:580:02:01

So they're kind of April showers,

0:02:010:02:03

but a lot, lot earlier - still in February.

0:02:030:02:06

Now, as far as the second half of the week's concerned,

0:02:060:02:09

this big low is hanging around. It's not moving anywhere.

0:02:090:02:12

Does look as though, by the time we get to Tuesday,

0:02:120:02:16

those showers will start to ease.

0:02:160:02:18

So there'll be more of them on Monday,

0:02:180:02:20

but still a few left over for sure on Tuesday.

0:02:200:02:22

And then we're into Wednesday - remember, March 1st,

0:02:220:02:26

the first day of meteorological spring.

0:02:260:02:29

And the reason why we pick March 1st

0:02:290:02:31

is we like to work in blocks of three

0:02:310:02:33

when we average out the seasons.

0:02:330:02:35

So March, April, May is spring.

0:02:350:02:38

So here it is - the 1st of March,

0:02:380:02:41

the first day of meteorological spring.

0:02:410:02:44

Quite a bit of sunshine around across central and eastern areas

0:02:440:02:46

but we have got yet more weather fronts pushing our way,

0:02:460:02:49

so inevitably there will be some rain.

0:02:490:02:52

Early March - now, look at this pattern in the jet stream.

0:02:520:02:55

Typically, cold air is to the north of the jet stream,

0:02:550:02:58

mild air is to the south.

0:02:580:03:00

We're kind of going to be on the cold side of this jet stream

0:03:000:03:03

and it's quite a powerful jet stream as well,

0:03:030:03:05

and it could well be sending some pretty nasty areas of low pressure

0:03:050:03:09

in our direction once more.

0:03:090:03:11

Way too early to say just how windy or wet it's going to get,

0:03:110:03:15

but I think suffice to say

0:03:150:03:17

it is going to be an unsettled start to March.

0:03:170:03:20

There'll be some rain around, there'll be some drier spells

0:03:200:03:23

as well, but because we're on the colder side of the jet,

0:03:230:03:25

there certainly will be

0:03:250:03:26

some chilly weather about.

0:03:260:03:28

Thanks for watching.
