Hello. If you were watching yesterday evening,

0:00:020:00:04

I was telling you about how quiet

0:00:040:00:05

the weather picture is at the moment.

0:00:050:00:07

We've got high pressure sat across the country and that

0:00:070:00:09

will stay with us, certainly for the next six days and for some,

0:00:090:00:12

beyond that as well.

0:00:120:00:14

Of course, we've got that harsh,

0:00:140:00:15

winter cold weather across continental Europe and that

0:00:150:00:18

has been creeping into the UK and that process will continue

0:00:180:00:21

in the coming few days.

0:00:210:00:22

But with it,

0:00:220:00:23

we've seen some lovely sunshine.

0:00:230:00:25

Crisp weather as you saw there in London.

0:00:250:00:27

However, we've got a weak weather front across the country

0:00:270:00:30

so we're seeing some quite significant contrast as you

0:00:300:00:32

saw there in Derbyshire.

0:00:320:00:33

Of course, the cloud does mean that it will be a mild night for many,

0:00:330:00:36

but where the cloud breaks, perhaps the Vale of York, the north and east

0:00:360:00:39

and particularly across the southern half of the country,

0:00:390:00:42

there will be a harsh frost.

0:00:420:00:44

-6 again, -7.

0:00:440:00:45

Plus we'll have some fog.

0:00:450:00:47

But once it does clear,

0:00:470:00:49

the sunshine looks more abundant as we head into Friday morning.

0:00:490:00:52

Do watch out for some freezing fog across central areas first thing

0:00:520:00:55

and perhaps the north-east.

0:00:550:00:56

But there is a better chance of brighter weather for

0:00:560:00:58

Northern Ireland, for Wales,

0:00:580:00:59

the north Midlands, Lincolnshire compared with recent days.

0:00:590:01:02

But it won't be warm, 5 or 6 degrees generally.

0:01:020:01:05

Over the weekend, those temperatures will lower.

0:01:050:01:07

As I mentioned, we're pulling in that colder, continental air.

0:01:070:01:10

So, again, Friday night into Saturday looks cold and again

0:01:100:01:13

there's a risk of some freezing,

0:01:130:01:15

patchy freezing fog as we head into Saturday morning.

0:01:150:01:18

Again, there's little wind to clear it,

0:01:180:01:19

but it should eventually clear, then we will see some sunshine.

0:01:190:01:23

But there is a weak weather front.

0:01:230:01:24

That weak weather front still with us throughout the weekend.

0:01:240:01:26

Actually, through the weekend,

0:01:260:01:28

it might give us a little bit of sleet and snow.

0:01:280:01:30

Just a few flurries, just letting us know winter is still with us,

0:01:300:01:33

but no significant amounts, we don't feel.

0:01:330:01:35

Still, only 4 or 5 degrees. It will be a cold weekend.

0:01:350:01:39

But a usable weekend because it should be mainly dry

0:01:390:01:42

with some sunshine.

0:01:420:01:44

But chilly by day and chilly by night.

0:01:440:01:45

And that's the way we start the new week.

0:01:450:01:48

But we're moistening up the air somewhat through the weekend

0:01:480:01:50

and the early part of the week.

0:01:500:01:52

So fog is likely to become more of an issue and just in time

0:01:520:01:56

for the return to work on Monday, for the rush hour.

0:01:560:01:58

There could be some quite dense and fairly widespread patches

0:01:580:02:01

of fog Monday morning.

0:02:010:02:02

Freezing fog, of course, because we'll have those frosts by night.

0:02:020:02:05

These are daytime temperatures - 4s and 5s. Still pretty nippy.

0:02:050:02:09

Tuesday, still the same across the bulk of the UK, but towards

0:02:090:02:12

the north and west, we're dragging in the south-westerly wind.

0:02:120:02:15

More cloud, milder Atlantic air and some rain,

0:02:150:02:18

but it doesn't really amount to anything.

0:02:180:02:20

But it's the first go, if you like,

0:02:200:02:22

it's the first low pressure and weather system to have a go at

0:02:220:02:25

clearing out this dominant area of high pressure which

0:02:250:02:28

has been with us all this week.

0:02:280:02:31

That cold air across the continent really has established itself.

0:02:310:02:34

It's got a lot of inertia.

0:02:340:02:35

We've got to really work to move that high pressure out the way.

0:02:350:02:39

You can see what an area it covers.

0:02:390:02:41

But, as we go through the early part of the week,

0:02:410:02:43

we will find that these low pressures are starting to push in.

0:02:430:02:47

Their momentum starting to move the rain and the stronger winds

0:02:470:02:50

into the north-west of the UK.

0:02:500:02:52

So there's still high pressure and still that cold, continental feel.

0:02:520:02:56

But gradually, we'll get the milder Atlantic winds,

0:02:560:03:00

at least into the north and west and it's how quickly those start

0:03:000:03:04

to erode that area of high pressure which will determine

0:03:040:03:08

how quickly we see our weather change from this cold, crisp,

0:03:080:03:12

sunny weather to the rainy, wet weather in the north and west.

0:03:120:03:15

It will take quite a significant area of low pressure to move

0:03:150:03:18

it out the way and it does look like later next week we will have

0:03:180:03:21

some gales or severe gales moving in with some rain.

0:03:210:03:25

But, for the meantime,

0:03:250:03:26

fog particularly becoming a problem, more frosty nights.
