28/07/2017 Weather for the Week Ahead

Hello there. Looks like remaining very changeable this month,

and well into next month as well. Let's not forget, though,

at this time of the year, when the sun does come out,

it will feel warm, as it did in between the showers here

in Stevenage in Hertfordshire on Thursday.

But the showers are never too far away.

They came all of a sudden with some hail and thunder -

a good day for spotting some rainbows.

Lots of showers, then, earlier on.

The one constant over the next few days is going to be

this area of low pressure to the north-west of Scotland,

and around the base of that low pressure

we're going to feed in these clusters of cloud

that will bring us some spells of rain.

Now, we start the day generally dry across England and Wales

with some sunshine in the morning. It looks like it will cloud over

and we'll start to see some rain arriving from the south-west.

The timing, the northward extent of the rain still in doubt.

Showers more likely further north,

especially across Scotland and Northern Ireland,

but warm enough in the sunshine.

Temperatures in eastern England 21 or so.

But that rain looks like it will develop more widely quite quickly,

that first pulse of rain in those weather systems

driving across much of England and Wales,

quite heavy rain for a while, but it doesn't last too long,

and we've still got that area of low pressure to the north-west.

There is still a trailing area of rain

that at the moment looks like it's mainly out in the English Channel,

but it's likely to come back in again,

not just in the extreme south-east of England

but for many southern areas too.

And then there's a slice of much drier weather for the weekend

for Wales, the Midlands, Northern England,

where there'll be very few showers, some warm sunshine.

Showers more likely across Scotland and Northern Ireland,

where they'll be closer to that persistent area of low pressure.

This weather system here has got to get its act together,

probably, again, as we head into the evening,

to push some heavier rain eastwards across England and Wales.

Again, it doesn't last too long.

Again, we've still got that area of low pressure.

So whilst we see the back of the overnight rain,

we're going to start the day with lots of showers out to the west,

some heavy, with some hail and thunder,

and those showers will push their way eastwards through the day,

where temperatures could get as high as 21 Celsius or so.

That low pressure still there towards the north-west -

if anything, it's drifting closer to Scotland and Northern Ireland.

Around the southern edge of that, there'll be some blustery winds,

but probably not that many showers

across the bulk of England and Wales. Some sunshine here.

But slower-moving, heavier showers for Northern Ireland, Scotland,

and perhaps the far north of England

where temperatures are again struggling to 17 or 18 degrees.

And even into Tuesday,

there'll still be a mixture of sunshine and showers.

Again, some heavier ones towards the north-west,

but this time, we could see more showers across England and Wales.

And those temperatures again,

17 in the north, 22, perhaps, in the south-east.

There's a ridge of high pressure tantalisingly close,

however, this is more dominant as we head into the middle of next week.

Big area of low pressure coming in from the Atlantic

and more waiting in the wings too.

So as we head further into next week,

we've got the jet stream in this sort of position.

Most of the UK is going to be on the cooler side of that jet stream,

and the jet stream will pick up these areas of low pressure

and drive them across the UK.

So what does that mean? Well, basically it means

it's going to remain very mixed. We'll alternate, probably,

between days of sunshine and showers, which could be quite heavy,

whereas other days will see some spells of rain

and for much of the time it may be quite windy

and it will stay on the rather cool side as well.

Not what we would hope for or expect at this time of the year.
