09/08/2017 Weather for the Week Ahead

It is that time again where we give you some detail about what's

coming up on the weather front in the next few days and look a little

further ahead.

Let me take you back a couple of days,

nothing wrong with that summery scene from Bridlington.

But if I take you back to the start of Tuesday, what a transformation.

I could sing at this point what a difference a day makes

but I like you too much.

Bridlington wasn't alone in experiencing a very wet Tuesday.

It was the top of this pile and this isn't all of the figures,

there was rain after those readings were taken.

Coming from an active weather front tied in with an area of

low pressure.

The low pressure itself is migrating a bit further

north into the heart of Scandinavia but it is leaving behind this

weather front and a slow-moving front at that.

It just about gets away from Birmingham in the first

part of the day but it lingers across East Anglia and the

south-east and because of that the Met Office have warnings out.

We could see rainfall totals in some areas getting up to 60-80mm.

But it's not like that everywhere.

Many northern and western parts beginning to

benefit from this area of high pressure.

Which really wants to dominate the whole of the British Isles

but you will notice it does take a time before we see the last

of Wednesday's rainfall getting away from East Anglia and the south-east.

Then many may well enjoy consecutive dry days and I say that with

some relish because we haven't said it too often so far this summer.

Can we make it three in a row? Not really.

It's obvious a low pressure close to Iceland is throwing its fronts

with a combination of wind

and rain increasingly down and across all

parts of the British Isles through Friday but it will take a

while before it gets down into that south-eastern quarter.

Is this variability going to continue on into the weekend?

Thankfully, no, not really.

Just for long enough we are going to see a build of high pressure

moving in.

The system from Friday will clear away from the south-east.

It will be a mixture of dry weather and the odd passing shower.

Not too much in the way of breeze,

you'll notice those isobars are widely spaced.

Here comes Sunday and again devoid of frontal systems

so many areas could get away with another dry day.

Lurking behind, signs of things to come

because as we get into the start of

next week the jet stream will take

up this orientation and it is the

feature that steers weather

systems and it is pointing towards the British Isles.

High pressure is there to be had tantalisingly close,

just to the south but along the line of the jet stream

and to the north,

that's the mechanism that will steer

these areas of low pressure close

to us with high pressure killing the activity as they come our way.

Because that flow is coming from a relatively cool Atlantic

the temperatures will show no sign of a heat wave.
