17/07/2017 Weather for the Week Ahead

Hello. There is some quintessential British summer weather coming

up this week, briefly hot, thunderstorms and then cooler again.

Now, the heat will boost temperatures close

to 30 Celsius in the hot spots again over the next few days,

and it's not just a south-east England heat wave.

The heat will be building right across the UK along with the

humidity, but then, by the end of Tuesday into Wednesday,

we'll see some thunderstorms breaking out.

They'll be spreading north,

but of course not everybody will catch them.

And then, by the end of the week,

it's the Atlantic weather taking over again, with sunshine

and showers and temperatures back much closer to average

for the time of year, and it'll be a windier story by then, as well.

Let's take you through this roller-coaster ride over this week

before giving you an idea of what to expect next week by starting

with the big picture for Monday.

And this is why things are settling down and heating up,

high pressure in control.

Don't be fooled by the cool start to Monday morning.

Temperatures head up very quickly in the sunshine.

Maybe on the hazy side the further south you are,

and for the Northern Isles there'll still be some cloud

and outbreaks of rain becoming confined to Shetland.

Temperatures, though, for much of the UK by Monday afternoon

in the low to mid 20s.

But as we go into Tuesday,

although the hot weather is still with us, this weather disturbance

could prove to be a thundery end to the day for some of us.

Notice how, though, around that we start to drag in the hotter

air from the Continent, boosting temperatures and humidity.

So plenty of very warm to hot sunshine again during Tuesday.

Across southern parts, though, some cloud will begin to build.

But even across western and northern parts of Scotland, temperatures will

reach maybe around 27 Celsius and the hot spots again near 30

Celsius, probably towards the south and south-east of the UK.

Some thundery showers developing towards the end of Tuesday

pushing northwards into Wednesday,

becoming an area of thundery rain affecting northern parts of the UK,

and for the rest of England and Wales on Wednesday there

will be quite widely showers and thunderstorms breaking out

and still some heat and humidity,

but especially now across East Anglia

and south-east England again near 30 Celsius in the hot spots,

whereas elsewhere it just turns a bit cooler.

And as this weather front moves through as we start

off Thursday, for many of us it'll be cooler and fresher,

a little ridge of high pressure keeping a lot of fine

weather during the first part of Thursday,

heat and humidity gradually coming down in East Anglia

and south-east England,

but then low pressure coming in from the Atlantic,

producing stronger winds, showers and some outbreaks of rain towards

the north-west of the UK and pushing across all

parts as we go from Thursday into Friday as this weather front moves

its way southwards, so along that weather front again a spell of rain.

Maybe on Friday the far south-east staying dry,

maybe parts of north-east Scotland,

but you can clearly see it's now an Atlantic-driven weather

pattern by Friday, and those temperatures are down much

closer to average for the time of year, and the wind has picked up.

The weather pattern going into next weekend and, in fact,

the following week,

we'll have high pressure always quite close to the south,

low pressure near northern parts of the UK producing this

Atlantic-driven wind flow where temperatures are close to average.

And actually, it's quite windy,

especially the further north you are.

The weather you get depends on

how close you are to these weather systems.

Across northern parts of the UK, Scotland, Northern Ireland,

northern England, you're close to low pressure,

there could be spells of rain, showers

but, with some sunshine following on behind, quite windy.

Relatively dry and warm compared to that across southern

parts of the UK, but we can't rule out some wet weather at times

here, too, and temperatures just close to average.
