Hello. Our weather fortunes are about to take a significant dip.

0:00:020:00:06

Forget about spring, we are heading for a shot of winter,

0:00:060:00:10

make no mistake about that.

0:00:100:00:11

Across central and southern parts of the British Isles,

0:00:110:00:15

we've enjoyed a burst of spring.

0:00:150:00:16

That comes very much to an end as we get on into Saturday.

0:00:160:00:20

The reason for the change is that an area of low pressure which has

0:00:200:00:25

fed in relatively mild air from the south-east

0:00:250:00:28

has been elbowed aside.

0:00:280:00:29

It's all about an area of high pressure,

0:00:290:00:31

feeding in this bitter easterly wind

0:00:310:00:34

to all parts of the British Isles as we start the weekend.

0:00:340:00:36

Continuous snow for a time across southern England and Wales.

0:00:360:00:40

Further north, wintry showers abound,

0:00:400:00:42

particularly but not exclusively on the central and eastern sides

0:00:420:00:46

of the heart of England there.

0:00:460:00:47

And the temperatures, when you add in the strength

0:00:470:00:50

of that wind, we're talking about 50-60 miles an hour gusts,

0:00:500:00:54

it's down to -7 or -8 and there are Amber warnings

0:00:540:00:57

already for snow and ice from the Met Office.

0:00:570:01:00

They run from about tea-time on Saturday through

0:01:000:01:05

the course of the night and on into the first part of Sunday.

0:01:050:01:09

That high pressure very much the dominant feature, though.

0:01:090:01:12

Could well be that period of snowfall there

0:01:120:01:16

across southern parts for a time on Sunday.

0:01:160:01:19

As that eases away towards the west, things begin to quieten down.

0:01:190:01:22

Fewer showers.

0:01:220:01:24

The latter part of Sunday, what you've got to cope with

0:01:240:01:28

is pretty much what has happened through Saturday and Saturday night.

0:01:280:01:32

The day, though, for the absence of the showers,

0:01:320:01:34

no warmer by any means at all.

0:01:340:01:37

Any signs of a recovery in those temperatures? Yes.

0:01:370:01:40

High pressure begins to drift away from Scandinavia

0:01:400:01:42

and cuts off the coal supply of air from the northern parts,

0:01:420:01:46

from Siberia, and we're beginning to pick up a maritime track.

0:01:460:01:51

Still quite a breeze across the south-eastern quarter

0:01:510:01:54

and from that we will still see some wintry showers,

0:01:540:01:56

he North York Moors, perhaps, the Wolds of Lincolnshire.

0:01:560:01:59

Elsewhere, a dry start to the week.

0:01:590:02:02

But no real warmth in sight.

0:02:020:02:05

Still we look, as we move into Tuesday, Wednesday,

0:02:050:02:09

this area of high pressure still the dominant feature,

0:02:090:02:12

still a lot of dry weather.

0:02:120:02:14

Temperatures slowly beginning to recover from that

0:02:140:02:17

cold snap that all of us will endure during the course of the weekend.

0:02:170:02:22

Quite a bit of sunshine around, quite a bit of dry weather

0:02:220:02:25

and here, by Tuesday,

0:02:250:02:26

not quite double figures but not nought,

0:02:260:02:29

one, two, or three degrees.

0:02:290:02:31

As we move through towards the middle of the week,

0:02:310:02:33

the high-pressure begins its journey slowly away down towards

0:02:330:02:37

the south-western approaches.

0:02:370:02:40

Tending to open up the door for at Atlantic weather systems,

0:02:400:02:43

gradually they work their way through to northern

0:02:430:02:46

and western parts of Scotland, maybe flirting with Northern Ireland, too.

0:02:460:02:50

At least with that mild Atlantic flow,

0:02:500:02:53

beginning to dominate across the British Isles, those temperatures

0:02:530:02:56

in one or two spots beginning to get back towards double figures.

0:02:560:03:01

That is the trend that we see as we move into the second half

0:03:010:03:05

of the forthcoming week. It comes at a price.

0:03:050:03:09

There is no doubt about it, as we look towards the Atlantic,

0:03:090:03:13

we will introduce low-pressure systems

0:03:130:03:15

for the second half of the week.

0:03:150:03:17

Something akin to that, perhaps,

0:03:170:03:19

with wet and windy spells of weather.

0:03:190:03:21

So, slowly, things will turn less cold

0:03:210:03:24

but they will turn more unsettled and very wet and windy at times.

0:03:240:03:28

Goodnight.
