27/01/2018 Weather for the Week Ahead

It's going to be a real rollercoaster ride

over the week ahead and you'll see what I mean

when we took a look in more detail at the outlook.

Friday, though, was the coldest day

of the past few days,

but at least we had some sunshine

and most places were fine and dry.

Things are turning milder this weekend.

We're getting Atlantic winds strengthening

and the milder air comes in behind

this weather front here,

which is driven by a deep low pressure

heading close to Iceland.

So, here's the rain

coming on that weather front.

It could be quite a heavy rain

in the morning across some western hills.

Through the afternoon, the rain pushing eastwards

becomes light and patchy.

We keep a lot of cloud for most of England and Wales.

More likely to see the sunshine

in Scotland and Northern Ireland

accompanied by a few showers,

quite windy here as well.

For many of us, quite a blustery sort of day,

but it's a mild day.

Temperatures higher than they were on Friday.

That deep area of low pressure

could bring some severe gales, though,

across the far north of Scotland overnight

before the winds ease down a touch

and then we've got this returning frontal system

which is making a beeline for Scotland,

where we'll see some outbreaks of rain and drizzle.

Many other areas look like being dry on Sunday.

It looked like being quite cloudy as well.

It'll be breezy out there,

but very mild -

temperatures probably even higher on Sunday,

even in the cloud, but if you do get some sunshine

where we've got a bit of shelter from the high ground

such as Cheshire, north-east Wales,

it could be 15 degrees.

That's probably going to be the best it gets

over the next few days.

Things are changing on Monday

because that weather front that was bringing

the rain across the north

is going to edge its way southwards

so we'll see the weather changing

across northern parts of the UK,

drier conditions following in here.

There's our area of rain and just ahead of it,

we could have some really quite strong and gusty winds.

The rain arriving across southern England in the day.

It's here we'll see the highest temperatures.

A bit of sunshine further north,

but things are beginning to cool down a touch.

That weather front bringing the rain

is sitting to the south of the UK.

Probably by Tuesday,

the bump of high pressure

means a chilly night ahead.

However, these weather fronts

are coming back in again from the Atlantic,

never fully clearing away,

so it may well be a chilly start,

bright start with some sunshine,

particularly for eastern areas.

But then we see this rain coming back in again

from the south-west

and it could be quite heavy rain for a while as well,

but things are moving fairly quickly,

the winds picking up.

That rain rushes its way eastwards

into the near-continent

and instead we get some sunshine

following on behind on Wednesday

and some showers.

Quite a range of temperatures -

5 degrees, chilly in Glasgow,

10 degrees in London.

So, as we head later on into the week,

low pressure sitting very close to the UK.

The rain having pushed through,

we're going to keep the showers going.

There'll be quite a chilly wind as well

and with that low pressure

and that sort of wind direction,

we're drawing down some colder air.

Now, this is where we get the rollercoaster.

You can see this fluctuation in temperatures.

It goes all the way across

the other side of the Atlantic

and that fluctuation will propagate its way

across the Atlantic into the UK.

It's all due to the position

of the jet stream, of course,

the upper level winds

moving their way northwards

and then southwards

and for the surface winds,

the winds that we will feel,

you get this change one day

from a northerly,

one day to a south-westerly

and back to a northerly

as that pattern moves across the Atlantic.

So where we have the northerly winds

or the north-westerly winds,

it'll be colder.

There'll be more sunshine around them,

maybe some showers, too.

When we have the south-westerly winds,

it means we'll have more cloud.

There's perhaps the chance of some rain,

but it will also be much milder.

Goodbye.
