Hello. There is some quintessential British summer weather coming

0:00:030:00:07

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

0:00:070:00:10

Now, the heat will boost temperatures close

0:00:100:00:12

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

0:00:120:00:17

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

0:00:170:00:19

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

0:00:190:00:23

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

0:00:230:00:26

we'll see some thunderstorms breaking out.

0:00:260:00:28

They'll be spreading north,

0:00:280:00:29

but of course not everybody will catch them.

0:00:290:00:32

And then, by the end of the week,

0:00:320:00:33

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

0:00:330:00:36

and showers and temperatures back much closer to average

0:00:360:00:39

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

0:00:390:00:43

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

0:00:430:00:46

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

0:00:460:00:50

with the big picture for Monday.

0:00:500:00:51

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

0:00:510:00:54

high pressure in control.

0:00:540:00:56

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

0:00:560:00:58

Temperatures head up very quickly in the sunshine.

0:00:580:01:01

Maybe on the hazy side the further south you are,

0:01:010:01:04

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

0:01:040:01:06

and outbreaks of rain becoming confined to Shetland.

0:01:060:01:09

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

0:01:090:01:11

in the low to mid 20s.

0:01:110:01:14

But as we go into Tuesday,

0:01:140:01:16

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

0:01:160:01:19

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

0:01:190:01:23

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

0:01:230:01:26

air from the Continent, boosting temperatures and humidity.

0:01:260:01:30

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

0:01:300:01:34

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

0:01:340:01:38

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

0:01:380:01:41

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

0:01:410:01:45

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

0:01:450:01:48

Some thundery showers developing towards the end of Tuesday

0:01:480:01:51

pushing northwards into Wednesday,

0:01:510:01:53

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

0:01:530:01:56

and for the rest of England and Wales on Wednesday there

0:01:560:01:59

will be quite widely showers and thunderstorms breaking out

0:01:590:02:01

and still some heat and humidity,

0:02:010:02:03

but especially now across East Anglia

0:02:030:02:05

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

0:02:050:02:08

whereas elsewhere it just turns a bit cooler.

0:02:080:02:11

And as this weather front moves through as we start

0:02:110:02:13

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

0:02:130:02:17

a little ridge of high pressure keeping a lot of fine

0:02:170:02:19

weather during the first part of Thursday,

0:02:190:02:21

heat and humidity gradually coming down in East Anglia

0:02:210:02:24

and south-east England,

0:02:240:02:25

but then low pressure coming in from the Atlantic,

0:02:250:02:28

producing stronger winds, showers and some outbreaks of rain towards

0:02:280:02:31

the north-west of the UK and pushing across all

0:02:310:02:33

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

0:02:330:02:37

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

0:02:370:02:40

Maybe on Friday the far south-east staying dry,

0:02:400:02:42

maybe parts of north-east Scotland,

0:02:420:02:44

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

0:02:440:02:47

pattern by Friday, and those temperatures are down much

0:02:470:02:50

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

0:02:500:02:53

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

0:02:530:02:56

the following week,

0:02:560:02:57

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

0:02:570:03:00

low pressure near northern parts of the UK producing this

0:03:000:03:03

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

0:03:030:03:06

And actually, it's quite windy,

0:03:060:03:08

especially the further north you are.

0:03:080:03:10

The weather you get depends on

0:03:100:03:11

how close you are to these weather systems.

0:03:110:03:13

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

0:03:130:03:16

northern England, you're close to low pressure,

0:03:160:03:18

there could be spells of rain, showers

0:03:180:03:20

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

0:03:200:03:22

Relatively dry and warm compared to that across southern

0:03:220:03:25

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

0:03:250:03:28

here, too, and temperatures just close to average.
