26/09/2016 Weather for the Week Ahead

Hi, there. There's a few days to go but when the stats are all in,

September will have proved to be a notably warm month for many of us.

It looks like ending on a cooler note.

In the process, there's going to be some wind and rain around,

particularly across the more northern

and western parts of the UK.

Further south than east, there will still be some rain but

generally it will be dry here and the winds won't be as strong either.

And certainly we start Monday with most of the rain out West,

particularly across parts of Devon, Cornwall and Wales,

where there are warnings in force.

Whereas further east across England, the odd shower

but a lot of dry weather to start proceedings.

Some of this showery rain pushing its way up the Irish Sea

into North-Western parts of England,

a glancing blow for Northern Ireland.

A lot of dry weather across Scotland at this stage.

The odd shower across the north-west corner.

A chilly start to the day here. As we go through the day,

this rain is going to push its way in a northerly direction,

really, pushing up into the southern half of Scotland.

Northern Ireland probably escaping most of the rain.

Northern England seeing some wet weather later

but East Anglia and the south-east, you'll notice, still largely dry,

where it stays wet out West it will be a pretty cool-feeling day,

13 or 14 Celsius.

Some dampness still to come as we head into the night,

although I think it'll tend to fade away.

Just dribs and drabs left behind by the time we get into Tuesday.

Particularly around exposed coastal areas,

up over the hills there'll be some drizzly rain and fog too.

We could see some breaks in the cloud cover

and because it's quite a muggy air mass,

temperatures could get up into the low 20s,

if you see some decent sunshine.

Quite windy, though, across the north of Scotland in particular.

As we head towards the middle of the week,

the next weather system on the conveyor belt comes steaming

in off the Atlantic, targeting the north-west of the UK with

some rain, but more importantly, some pretty strong winds too.

We'll see some gales whistling across Scotland in particular,

so watch out for warnings for this part of the world.

Some rain here but again, further south and east, drier, brighter,

warmer up, until the low 20s and the wind won't be so strong either.

But this weather front's important.

As it starts to head its way south-eastwards,

there's a cold front and on Thursday

it'll be pushing some rain in across England and Wales.

Probably not making it to the far south-east

till late on in the day.

But behind that, cooler air starts to come in,

so temperatures somewhat lower, despite some sunshine.

There'll be some blustery showers across Western Scotland,

Northern Ireland as well.

Still some relative warmth across the far south-east.

But that front looks like clearing its way south-eastwards on Friday,

the last day of September, and then we're all into that sort of

cooler feed of West or north-westerly winds.

There will be some sunshine. But still some showers again,

particularly across the north and west and temperatures not as high

as they have been across the south-east and distinctly chilly

in the breeze further north and west.

So, why is the weather beginning to turn cooler?

Well, the reason is the jet stream and it's going to start to head

its way southwards as we end the week, as we end the month.

And with the jet stream to the south of us we go into October,

that allows cold air to come in from the Arctic.

Now, don't go away with the idea

that it's going to get desperately chilly.

By no means, but certainly cooler than it has been

as we turn the month, as the blue shades indicate.

And so, for the first few days of October at least,

it does look like a slightly different complexion to the weather.

Certainly chillier than it has been for a good few of us.

Sunshine and showers and a risk, just a risk,

of some overnight frost.

So, some changes coming up and Louise Lear will be with you here

again tomorrow to update you on the detail.

GUNSHOT The situation has now escalated.
