07/09/2017 Weather for the Week Ahead

Hello. Sometimes in weather, there are moments that take

your breath away. They came aplenty with Hurricane Harvey in Texas,

and they're coming again now with Hurricane Irma in the Caribbean.

This is just breathtaking.

This is a satellite picture from Wednesday of the eye

of Hurricane Irma passing directly over Barbuda.

Which means that Barbuda went from catastrophic winds one moment to

barely a breath of wind in the eye, and then catastrophic winds again.

Of course, Barbuda feeling the of full force of Irma,

as did St Martin, which also had landfall.

Now it's barrelling towards Puerto Rico during Thursday.

Watch out, north coast Dominican Republic, Haiti, and then

onto the Turks and Caicos Islands, Cuba and eventually Florida.

Though there's still some uncertainty about that.

And whilst Irma is not now having a direct impact

on our weather, what happens with Irma after Florida,

as remnants feed out into the Atlantic,

does bring us some uncertainty in our longer-range forecast,

as we'll see in just a moment.

But let's get back to our weather and how that's

developing during Thursday.

Of course, it's a much quieter affair, though there is a

weather system coming in from the Atlantic, initially bringing some

rain at the start of the day to northwest Scotland.

Quite heavy here, quite windy with that.

But the rain is on the move southeast during the day

across the rest of Scotland, Northern Ireland,

to Wales and western England.

Eastern parts of England, with the exception of the odd shower,

stay driest for longest, but even here, getting into the evening,

there should be outbreaks of rain moving in.

Those temperatures clearly suppressed where you've got

the heaviest rain and the strongest winds.

Eventually, we see some outbreaks of rain reaching down towards

southeastern parts of Britain as we go through Thursday and Friday.

But this weather front comes a player in the weather

across South wales, southern England on Friday.

Still something to play for in the detail,

but some spots could have quite a bit of rain all day long here.

Elsewhere, some sunny spells, heavy showers to be had.

Catch one of those, they could be thundery, perhaps with some hail.

Now that front does clear away,

but still low-pressure nearby as we look at the picture for Saturday.

Strong winds to the south and west of the UK,

lighter winds further east. Then a case of showers breaking out again.

So some drier, sunnier moments, but some heavier showers to be had

and still on the cool side.

Though if you find some sunshine, may not feel too bad.

Cool night to come, Saturday night into Sunday,

a little ridge of high pressure, a gap between weather systems,

but that gap isn't very big, because here comes another on Sunday.

So again beginning to spread rain southeastwards across the UK

and with this, the winds picking up as well.

Particularly down towards the South and South West,

from Sunday into Monday.

Around this deep area of low pressure, the isobars squeezed.

This could be a troublemaker, Sunday into Monday.

And again, where those isobars are close together, across the South

and South West, a risk of gales, perhaps severe gales in places,

so could be some impact from this.

Lighter winds further towards the North East,

showers around again, and some heavy ones to be had.

Going into Tuesday, that low trying to move away.

Still in a breezy, cool flow of weather.

But looks like a ridge of high pressure's trying to come in,

but there are more weather systems to come next week.

The bulk of next week is looking changeable and unsettled.

But by the end of the week and into the following weekend,

it looks like high pressure will try to establish itself in the Atlantic.

That would disrupt the flow of weather, given us

perhaps longer settled spells in between weather systems.

But a word of caution,

the computer forecasts are not yet taking into account what's

left of Irma and Jose, which has followed on behind Irma,

and how that's going to feed into to the weather across the Atlantic.

So it is a very big "watch this space".

You want to get rid of me.
