02/12/2017 Weather for the Week Ahead

Hello, thanks for joining me. We'll speak with some confidence

about what we expect to see by way of weather

until the middle of the forthcoming week,

and then we'll pick out the trends for a slightly longer term.

Let's really boost the confidence levels

and take a look at what happened in November with regard to sunshine.

You'll see from the scale that many were well above

what we would expect at this time of year.

Does that mean we've experienced a heatwave? Most certainly not.

Many locations in England and Wales around about the average,

Scotland and Northern Ireland below par

because these areas have been fully exposed

to quite a lot of northerly wind

which has brought that prospect, as many of you will have seen of late,

of something really quite wintry.

Now, through the course of the weekend we swap that cold air

that many have seen through the week for something a good deal milder

coming in from the Atlantic thanks to an area of high pressure

just to the west of Ireland.

So no longer that bright, fresh start to the day.

A little bit milder, perhaps,

and certainly more cloud across western areas

than we've seen of late.

A frontal system across the northern parts of Scotland.

The temperatures just showing signs of gaining a degree or two.

This transition to something slightly milder from the Atlantic

will take a good part of the weekend.

That feature I was talking about in the north of Scotland for Saturday

becomes the feature across the south of Britain as we start Sunday.

That gradually creeps away

and brighter skies percolate from the north

ever further south towards the Midlands and southern England.

By this stage, look at that - 7 to 11

rather than the 3, 4, 5, 6, 7

that many have seen for the past few days.

All of that is coming to us thanks to this big area of high pressure

as we start the new week, out towards the western side of Ireland,

the flow coming in from the north-west,

and having seen that sort of mildish, cloudy day on Sunday,

we do it all over again on Monday.

This stage, 8, 9, 10, 11 degrees or so.

So the temperatures making double figures

across the southern half of the British Isles.

Come Tuesday, that high pressure will have slid down towards France

so we're getting more of a south and south-westerly breeze.

That also helps to keep the temperatures up -

we will be frost-free as we start the new week.

And then from Tuesday on into Wednesday,

that high pressure is still there across the southern half of Britain,

but because it's that bit further south it's opened the door for

developments to move in to the north and west of the British Isles

from the Atlantic. So wet and windy fare

for parts of Scotland and Northern Ireland by this stage,

but look at the temperatures.

No longer the 3, 4, 5, look at this -

9, 10, 11 or 12.

And then Wednesday could well be a wet and windy sort of day.

Certainly later in the day, on into Thursday,

this low pressure really churning its way in from the Atlantic.

By the end of the week

we think it'll have moved over towards Scandinavia.

We don't want to leave a vacuum behind,

so we bring the high pressure in and that generates a northerly.

Now that goes back to where we were in the middle of this week,

and you know what happened.

There could be some snow showers in that forecast,

particularly across northern and eastern parts.

Then, towards next weekend, that high pressure retreats,

we bring a low pressure in close by to Scotland, and that generates

a coolish sort of north-westerly breeze.

And there could well be quite a bit of that,

because we have that juxtaposition of the high and the low.

So it could be for a time that we see something really quite cold,

certainly windy at times,

and there could, whilst we have that northerly especially,

have that prospect again of seeing something really quite wintry.

Enjoy your weekend.
