30/11/2017 Weather for the Week Ahead

Hello there. For the past few days we've seen temperatures dropping

day on age and night on night,

but it's not going to be that way for too much longer.

What we're seeing at the moment, though,

high-pressure out to the west, low pressure to the east,

and the cold air coming down on a northerly wind

and that cold air is getting colder and colder

right now, so we've got

a widespread frost on Thursday,

but for most places, a dry and sunny day.

Showers Northern Ireland,

westernmost parts of Wales,

far south-west of England.

Most of the wintry showers

driven on by a strong and cold wind

across easternmost parts of England

and eastern Scotland.

Those temperatures in the afternoon

3 to 5 degrees typically,

so it will be a cold day.

So we're drawing down the colder air,

we've got the clearer skies

and we're going to have more frost round on Friday morning.

Again, temperatures in rural areas

could be down to about -6 or so.

More wintry showers

for eastern parts of England,

even a few in the south-east of England,

before they fade away.

Still got the sunshine

across much of England and Wales,

but coming into the north-west,

coming into Scotland and Northern Ireland,

the wind direction is changing.

More cloud is arriving

and perhaps a little bit of rain

and eventually that will start

to lift the temperatures

but Friday still

another cold day.

However, as we head into the weekend,

we've still got high pressure out to the west

but it's receding a little bit

and we're allowing air to come in

from the Atlantic around the top

of that high pressure

and push its way down into the UK,

so the really colder air

is limited more to the south-east on Saturday

and then it gets pushed

into the near continent,

as milder Atlantic winds slowly arrive

and it is quite slowly.

The temperatures will be slow to rise.

They'll be a lot more cloud around on Saturday,

pretty much across the board.

Those temperatures 6, 7,

perhaps even 8 degrees or so.

Most places will be dry but rather cloudy.

And on Sunday, we've still got

cloudy skies for many places.

A little bit of rain this time

pushing southwards into England

and Wales but boosting the temperatures.

It won't be as cold overnight

and by day, we could get temperatures

of 10 or 11 degrees.

There's the high pressure still

and we're still feeding around the top of that

this Atlantic air.

A couple of weather fronts on the scene

but weakening all the while,

most of the rain sitting really

probably to the north of Scotland, so,

again, more westerly breezes

across the northern half of the UK,

light winds further the south,

so it could get a little bit chilly overnight

depending on whether the cloud breaks or not.

But, on the whole, cloudy skies and pretty mild,

temperatures 9 or 10 degrees.

Now as we head into next week,

look at the jet stream here.

It starts to buckle more

and that's going to be important.

North of the jet stream

we've got the colder air,

south of it we've got the mild air.

You can see how the shape

is beginning to change.

Now early on in the week,

the high pressure still more

towards the south and south-west,

allows us to draw that Atlantic air

feeding in cloudy skies

and bringing with it

some reasonable temperatures

for the time of year.

However, as we move into

the latter part of next week,

it looks like the high

will tend to get pushed away

more to the west

as the jet stream buckles

and we get this northerly flow returning,

so it will turn colder.

For a while, though, next week

fairly cloudy, quite mild conditions across the UK,

not much rain and then as the jet stream changes,

we get the northerly winds,

it gets progressively colder later next week.

There'll be more frost around,

there'll be more sunshine around,

but there could also be some wintry showers. Goodbye.
