29/07/2017 Weather for the Week Ahead

Hello. There is a glimmer of hope on the horizon,

but before we get there,

much of the forecast is going to be dominated by low pressure,

and the dominant low pressure over the next few days

is going to remain as it is right now

towards the north-west of the UK. Around the base of that low pressure

we're seeing these waving weather fronts

bringing pulses of cloud and rain.

One area of rain overnight,

never really clears away from the southern coast of England

and starts to push northwards again on Saturday.

For much of the day, Wales, Midlands,

East Anglia and Northern England

just seeing one or two showers and some sunshine,

the better day of the weekend.

And back northwards, closer to the low pressure,

we've still got the showers, particularly in Scotland -

some heavy ones here, and those temperatures very similar

to the past few days.

Now, this rain is developing, it's on this weather front here.

The wave on it is responsible for the developing rain

which looks like it will push northwards into England and Wales

on Saturday evening. Overnight,

it sweeps away with some stronger winds.

We still have that low pressure towards the north-west.

So we're back to square one, almost, on Sunday - sunshine and showers.

Initially quite a few showers across western areas, some of them heavy,

with some hail and thunder, and those should push their way

eastwards through the day on that freshening breeze.

Probably not that many showers

across the south-east corner of England,

and it's here we'll see the best temperatures.

Otherwise, 17 or 18 degrees - not that impressive

for this time of the year.

Still got low pressure in charge, not just on Sunday

but into Monday as well,

and it's sitting very close to Scotland and Northern Ireland

around the base of that. There's still some stronger winds

across England and Wales in particular,

where we could see a few showers, particularly across North Wales

and north-west England,

and probably more showers to come across Scotland and Northern Ireland

closer to the centre of that low pressure.

Again, temperatures 17 to about 22 degrees,

those numbers not really changing very much over the next few days.

Low pressure still around as we head into Tuesday, but it's filling.

You can get a sense of that because the number of isobars is reducing

so pressure is rising across that low.

So the area's less unstable,

so whilst we'll find a mixture of sunshine and showers on Tuesday,

the showers should be fewer, the showers should be lighter,

more places will be dry, and it may start to feel

just a little bit warmer as well.

Now, there is some warmer air trying to come our way

from the near-Continent.

Trouble is, whilst many eastern areas on Wednesday may be dry

with some sunshine, out to the west we've got freshening winds

and some rain on the way.

And that's because it's a big area of low pressure heading our way.

That will push some wetter, windier weather across all areas

around the middle part of the week, and then the low pressure

will sit very close to Scotland for a few days after that.

Recently, we've had a jet stream in this sort of position,

and that's where it's going to be later on next week,

hence low pressure, hence not particularly warm,

and hence the threat of some rain.

But we're going to find this jet stream buckling,

more amplification, and probably heading northwards,

so the lower pressure we've got in the middle of the week

by next weekend fades away

and slowly but surely, coming in from the south-west,

it looks like we'll see an area of high pressure building.

How quickly, and how far north it gets,

that's difficult to say at this stage.

We'll have a better idea over the coming few days.

But the weather will change - we'll see less of this,

like we saw actually on Friday, heavy showers

and some thunderstorms, and a bit more of this.

There was some sunshine around on Friday.

We'll see more of that next weekend,

and of course, with the sunshine, it should feel a bit warmer.

That's it from me - enjoy your weekend.
