14/12/2017 Weather for the Week Ahead

Hello. Thanks for joining me. We'll update you about

how the rest of this week is going to pan out,

then burst on through the weekend and give you some sense of

what's coming up in the run-up toward Christmas.

In the shorter term,

bit of a concern about the intensity of snow

that could break out across the south-west of Scotland.

Could even feature in the Glasgow area just in time for the rush hour.

On a day which is going to see plenty of showers,

again across many northern, western and southern Channel areas,

the further east you are, or through the Midlands,

I think you're in for essentially a dry day.

Not overly warm, certainly not as warm as in the south on Wednesday.

Plenty of showers overnight again,

pushed along by this north-westerly wind,

and plenty of north-westerly wind, especially across the south-west,

where again you're in for another gusty sort of night.

Out into Friday, I think the chances are

that the wind will have gone round northerly by that stage

and that has quite a bearing on the shower distribution.

Quite distinctive in that it pushes the showers

along these eastern, northern shores

with a few just rattling in to Northern Ireland

and down to the west of Wales and into the south-west.

Down the spine of the country there's plenty of sunshine to be had

but it does nothing for those temperatures - three to about eight.

If you're in the full extent of that northerly wind

it'll feel even colder than that.

The northerly doesn't hang around for too long -

from Friday into Saturday, just beginning to see those isobars

backing around more towards a westerly.

Certainly that's the case across the western side of the British Isles.

Just a little feature there ganging those showers up,

robbing Scotland, Northern Ireland,

the north-west of England and North Wales of sunshine

and putting a dent in the temperatures as a consequence.

But we continue that journey with the isobars

to come round even further to more of a south-westerly,

and weather fronts marching their way in from the Atlantic,

and it's a combination of those fronts

and that change of air mass direction,

from the south-west rather than the north,

that ushers the cold air over towards central Europe.

And for us, we look towards the Atlantic

and we'll do that for quite a while.

Notice that there is quite a wodge of mild air here

stretching right out into the Atlantic

so that is certainly going to do us through Sunday

and the first part of the forthcoming week,

but it's at the expense, this boost in temperatures,

of a loss of sunshine for many parts during Sunday.

You may not think that five degrees in Norwich is particularly special,

but we complete the journey into that great raft of mild air

as we get, as I say, into the start of the forthcoming week,

when the air is coming up and around this high pressure

which becomes the dominant feature in the south,

so tending to keep much of this southeastern quarter

that little bit drier. What weather fronts there are

tending to run up towards the north-western quarter of Scotland.

Notice those temperature. Monday, double figures.

Can we do it again two days running?

Given that supply of mild air, yes, we certainly can. Look at this.

Widely, temperatures will be in double figures at that stage.

And having set up that sort of regime,

I suspect that's the way we'll see it through the middle part of

the forthcoming week, and indeed towards the end of the week,

with that high pressure forcing low pressures up

and across the north-western quarter of the British Isles.

Quite how far up the high goes

or how far it sinks towards the Continent

open to some debate at the moment,

but generally with that air flow we'll keep things mild

or above average for the time of year.

There will be some spells of rain,

predominantly across that north-western quarter,

and because of the high, dry, yes,

but there will be some frost and maybe some fog.
