19/01/2016 Weather for the Week Ahead

Well, thanks for joining me. Let's see if this cold weather's going

to last for a few more days yet and the answer is yes,

it is, we've got more cold weather

on the way,

not desperately cold, but chilly.

In fact, very chilly first thing

in the morning on Tuesday across

southern and south-eastern areas

after a very, very frosty night.

But also frosty across

the northern half of Scotland.

Here, too, across the glens,

temperatures overnight have

been close to -10 degrees

and even more in one or two areas.

Now, for northern England

and for basically many western areas

of the UK, it's around 5, 6 degrees

during the afternoon,

but this part of the country,

the South East, really chilly day on Tuesday.

Some sunshine, yes,

but after a very frosty night,

those temperatures struggling.

You have to get down

to south-western parts of the country

before you get temperatures

of around 7 degrees there in Plymouth.

Chilly in Cardiff, 4 Celsius.

And just that little bit milder

there in Belfast, around 7 degrees.

So wherever you are, you get the message,

it's around 4 to 7 degrees

and it's going to stay like that

For Wednesday, then, high pressure

in charge of the weather here.

That's basically a block,

it stops this milder Atlantic air

sitting here coming our way.

It will eventually reach us

but not yet, not at this stage,

so this is Wednesday.

Another frosty start to the day,

a little bit of sunshine,

and a bit of cloud too.

You can see where the shade is,

indicating the cloud,

and some sunshine poking through

there across Yorkshire, Wales,

maybe southern parts of England as well.

And another chilly day,

around 3 to 4 degrees.

Then on Wednesday,

we start to see this area of high pressure

nudge away just that little bit

towards the east

and these weather fronts start

to make a little bit more progress.

That means that the jet stream's ramping up,

that means the jet stream

is pushing the milder, wetter, cloudier,

windy weather in our direction,

so you can see temperatures

already possibly into double figures

across some of these western areas.

And here's a look at the jet stream,

end of the week.

It's a quite strong one,

pushing the weather fronts

in our direction

and then it kind of grinds

almost to a halt, or rather, changes

direction and moves northwards

rather than zipping across us.

What does that mean?

Well, basically that is an indication that the milder air is going

to be grazing western areas of the UK, whereas the further east you are,

the more likely you are

to hold onto some of that colder air.

So imagine if the cold air is sitting

across the continent here,

it will be pushed in the direction

of East Anglia, but the milder Atlantic air

is reaching many western areas,

so this is where we've got the mild conditions,

11 degrees, say, in Cardiff,

but possibly colder for Norwich and London.

I've deliberately left out those temperatures just to give you

an indication that temperatures could be some 5, 6 degrees colder here

compared to what we might have across many western areas in the UK,

so the mild air is heading our way but not for everybody

and then next week, for us to get milder air,

we need a jet stream to cut straight across us,

but what's going to happen, this area

of low pressure will keep sending air from the south which will be

gnawing on the western areas of the UK,

so not really influencing

an awful lot of eastern areas of the country

and that just means that the floodgates will remain open next week

for perhaps, perhaps,

cos there's no certainty, for some of that colder air to once again return

to many eastern areas of the UK,

so it's a bit of a west-east split

over the next week or so.

Thanks for watching.

So, no-one pays tax here? No-one pays taxes.

BBC2 shows you how to do it.

I'd like to take you all offshore

to legally avoid tax.

It is a licence to print cash.

And how not to do it.
