18/11/2015 Weather for the Week Ahead

Thanks for tuning in to Weather For The Week Ahead.

A lot happening over the next few days -

quite a stormy end to Tuesday for some of us,

but also a very mild one,

and that's really been the story of November so far.

Temperatures quite widely across the country

have been in the mid-teens, but this weekend,

a big change on the way - quite a bit colder,

perhaps only 5 degrees for some of us.

Let's have a look at Storm Barney.

This is a picture sent in from

the south of Wales, from Neath,

as Storm Barney approached,

whipping up the seas here.

Gusts in some areas in excess of 80mph.

Not a very well-formed storm,

but the winds were very, very strong,

particularly across the southern flank

of the area of low pressure as it approached Wales

during the course of Tuesday evening.

But early on Wednesday,

it's much calmer across the country,

but the weather will go downhill quickly

across the northwest of the UK,

got another area of low pressure

bringing some rain and very strong winds.

I think wherever you are on Wednesday, eventually,

it's going to become very windy once again,

with a mixture of sunshine

and passing gusty showers,

and relatively mild again, still -

15 in London but already colder in Scotland.

This is a separate area of low pressure -

this is not Barney, this is low pressure

that'll bring that windy,

blustery weather with showers across

the northern half of the UK in particular.

As we head into Thursday, once that area

of low pressure is out of the way,

look at the change of the wind direction

across Scotland - it starts to come in

from the north and that heralds a change

in our weather to that colder weather

I just mentioned at the start of the weather report.

I think, on Thursday, colder across

the northern half of the UK,

but just temporarily -

we are going to see once more some milder,

wetter and windier weather

across the south of the UK.

It really will be just grazing

the far south of the country.

You can see the wind and rain

splashing in from the southwest of England,

across central southern England,

into the southeast, but by the time we get

to the Midlands, northwards, you can see

how much lower the temperatures are,

around 6-8 degrees Celsius.

Then Friday night into Saturday,

that colder air starts oozing from the north

and temperatures will start to really take a tumble.

So, on Saturday, it's a very chilly day,

also a very windy day.

You can see a lot of isobars here.

That means strong winds coming all the way

from the north and, actually,

I wouldn't be surprised if there's wintry weather

across the hills of Scotland

and also northern England -

you can see a hint of wintriness there

across the Pennines.

It's also the fact that it's going to be

quite windy that we'll feel so cold.

You can see 4 degrees there

for Leeds and Sheffield.

Only 7 degrees in London,

a couple of degrees below the average

for the time of year, and that cold, windy theme

continues from Saturday into Sunday as well -

again, a chance of one or two wintry showers.

The morning will be quite frosty,

but I think a lot of us on Sunday actually should have

quite a sunny, crisp, late autumn day,

but chilly - temperatures in many areas

will be only around about, say, 5-8 degrees Celsius.

So, that's Sunday. How about next week?

Well, high pressure across the Atlantic

is actually going to shunt

some milder air in our direction

once more, because the air goes round

high pressure like so,

so the milder air that sits in the Atlantic

gets sent in our direction

and it pushes that colder air

away from the UK back into the continent,

before another shot of colder air,

in the wings, is ready to come our way

quite possibly later in the week,

so really a lot of chopping and changing

from milder to colder,

back to milder and colder weather again,

as we head over the next five to ten days.

That's it - bye-bye.

We're looking for a trap street.

They're somehow making our eyes skate right over it.

It's called a misdirection circuit.
