25/08/2014 Weather for the Week Ahead

Hello. Over the week ahead, the jet stream will be

in a different position.

Still a long way South, so it's still not that warm,

but it's going to be a stronger westerly jet.

So a lot of our weather will be

coming in from the Atlantic.

And the jet stream tends to pick up

and develop areas of low pressure

and that's what we're seeing at the moment,

this low-pressure and weather fronts

spilling rain northwards and eastwards right now.

So it will be a warmer start

across England and Wales

and Northern Ireland on Monday,

but cloud and outbreaks of rain.

The brighter colours show

heavy rain coming into Wales,

the South-West in the morning,

pushing into the Midlands towards the South-East,

then more southern parts of Northern Ireland.

Blustery winds in Northern Ireland

and northern England.

The far north of England won't see much rain

and Scotland may stay dry with some sunshine.

North-west Scotland the place to be.

Maybe some late sunshine in the South-West,

some sharp showers.

A humid feel across southern parts of the UK.

But the rain continues into the night,

the rain band getting stuck

across northern England,

petering out to some extent

but still some showers wandering across

southern parts of England and Wales

where it will be particularly warm

into Tuesday morning.

Chilliest of all across Scotland

where we've got clearer skies.

Here we're more dominated

by this area of high pressure.

It's quite a cold high, moving down from the North

and it's starting to squeeze our rain away,

those weather fronts away.

And that area of low pressure too.

But it's a slow process.

For much of the day,

southern England, maybe South Wales

will be dull and damp.

If you head across North Wales,

the Midlands, northwards, it'll be brighter.

We'll see some sunshine at times

but probably quite a cool feel,

with that area of high pressure.

To the south we've still got the rather muggy air

and 19 or 20 is still quite likely.

But that weather front and the cloud with it

doesn't clear away from

the far South and South-West of England.

And these Atlantic systems are trying to push in,

pushing that area of high pressure

away into Scandinavia. What does that mean?

Most places will be dry on Wednesday,

some sunshine around.

Still cloudy in the far south of England,

the far South-West some drizzly rain,

and some patchy rain

coming into Northern Ireland later in the day.

That's the forerunner really

of these next weather fronts

and areas of low pressure

that are taking over later on in the week.

These weather fronts pushing

right away across the UK on Thursday

to bring cloud and outbreaks of rain,

some blustery winds perhaps.

The rain could be quite heavy at times,

even in the South,

where we've got warmer air in the South-East.

Some of the heaviest rain

likely to be in Western Scotland,

closer to that area of low pressure.

That's taken a shine to Scotland

and Northern Ireland by the end of the week.

It's not moving away very quickly.

Some blustery winds around

that area of low pressure on Friday

and a fresher feel across the South.

Even here, whilst there'll be some sunshine,

we'll get some showers,

possibly longer spells of rain

further north for Scotland and Northern Ireland.

Let's look ahead, and a lot of uncertainty, it has to be said.

The trend as we head into the beginning of September

should see some drier weather returning.

Some slightly higher temperatures.

But Cristobal, which is a tropical storm in the Caribbean at the moment,

could come across the Atlantic and influence our weather in some way.

A lot of uncertainty about that.

We'll probably start the weekend with low pressure over the UK still

bringing outbreaks of rain.

Then we're looking at this high-pressure to build

and become amplified from the South-West,

bringing some drier conditions

and hopefully some better temperatures as well.

But no doubt things will change over the next few days.
