Hello, there. For the time being, at least, we've lost that July heat.

0:00:020:00:05

In fact, we've probably already peaked this week -

0:00:050:00:07

yesterday we saw a high of 27 degrees,

0:00:070:00:10

but by Tuesday temperatures will be significantly lower.

0:00:100:00:14

20, 21 degrees, if we are lucky -

0:00:140:00:17

and there will be, at times,

0:00:170:00:19

some heavy and some persistent rain to come.

0:00:190:00:21

It will start off light and showery

0:00:210:00:23

across Wales and south-west England,

0:00:230:00:25

but then this area of low pressure

0:00:250:00:27

will move in and just enhance that rainfall

0:00:270:00:29

as we go through the day.

0:00:290:00:31

So, perhaps the best of the weather

0:00:310:00:32

on Tuesday is likely to be

0:00:320:00:33

across Scotland and Northern Ireland,

0:00:330:00:35

with just a scattering of showers.

0:00:350:00:37

Some patchy rain to begin with

0:00:370:00:38

in the south-east,

0:00:380:00:39

maybe a brief lull through lunchtime,

0:00:390:00:41

before some more heavier persistent rain

0:00:410:00:43

pushes into the south-west,

0:00:430:00:44

and we'll see the winds strengthening.

0:00:440:00:46

Just how far north that rain goes

0:00:460:00:49

is still open to question -

0:00:490:00:51

but look at these temperatures.

0:00:510:00:52

Significantly down on what we've been used to.

0:00:520:00:54

14 to 20 degrees at the very best.

0:00:540:00:57

Now, as we move out of Tuesday,

0:00:570:00:59

that rain still yet to clear away

0:00:590:01:01

from the south-east corner -

0:01:010:01:02

so, welcome news for gardeners and growers.

0:01:020:01:04

Some much-needed rain

0:01:040:01:05

across much of central and southern parts

0:01:050:01:07

of England and Wales -

0:01:070:01:08

but behind that low,

0:01:080:01:09

well, we'll start to see the wind swinging round

0:01:090:01:11

to a northerly or a north-easterly direction,

0:01:110:01:14

making it feel just that little bit fresher

0:01:140:01:16

on those exposed east coasts -

0:01:160:01:18

but on Wednesday a quieter day,

0:01:180:01:19

drier, with sunny spells coming through,

0:01:190:01:22

temperatures at around 16 to 22 degrees,

0:01:220:01:25

feeling a little better the further west

0:01:250:01:27

in a little more shelter.

0:01:270:01:29

As we move out of Wednesday,

0:01:290:01:30

we see this ridge of high pressure building,

0:01:300:01:33

so, things quieten down

0:01:330:01:34

for a day, at least, again.

0:01:340:01:35

We'll see this weak weather front threatening,

0:01:350:01:37

so, the best of the weather on Thursday

0:01:370:01:40

is likely to be across sheltered eastern areas.

0:01:400:01:42

Dry, with some sunshine, a scattering of showers

0:01:420:01:45

developing out to the west

0:01:450:01:46

as we go through the day.

0:01:460:01:48

17 to 23 degrees the high

0:01:480:01:49

by the middle of the afternoon.

0:01:490:01:51

Now, that weather front has yet to clear away.

0:01:510:01:54

It will do so during Thursday

0:01:540:01:56

into the early hours of Friday morning,

0:01:560:01:58

and will bring some showers with it

0:01:580:02:00

before, again, another ridge builds,

0:02:000:02:02

before the next system

0:02:020:02:03

waits in the wings across the north-west.

0:02:030:02:05

It's going to stay pretty changeable this week.

0:02:050:02:07

So, we could have some early showers

0:02:070:02:09

across the south-east corner

0:02:090:02:10

to clear away first thing on Friday.

0:02:100:02:12

Drier, brighter weather from the west,

0:02:120:02:15

before the next area of frame starts to show its hand

0:02:150:02:18

into the north-west by the end of Friday.

0:02:180:02:20

That will bring some wetter weather,

0:02:200:02:22

weakening all the time

0:02:220:02:23

as it pushes steadily east -

0:02:230:02:24

but for the start of the weekend,

0:02:240:02:26

stays pretty changeable.

0:02:260:02:27

It stays pretty windy at times,

0:02:270:02:29

and there will be some showery outbreaks of rain,

0:02:290:02:33

so, it's not all straightforward

0:02:330:02:35

for the start of the weekend.

0:02:350:02:36

Top temperatures around 18 to 23 degrees.

0:02:360:02:40

It probably won't come as a surprise to hear

0:02:400:02:42

that the jet stream

0:02:420:02:43

is sitting right across us at the moment,

0:02:430:02:45

allowing for this mobile westerly flow,

0:02:450:02:47

for the Atlantic frontal systems

0:02:470:02:50

to move in from day to day -

0:02:500:02:52

but, as we move out of the weekend

0:02:520:02:54

into the longer-term period,

0:02:540:02:57

it looks as though we'll see

0:02:570:02:58

more of an amplified jet stream,

0:02:580:02:59

and that's going to allow this high pressure to build

0:02:590:03:02

from the south-west,

0:03:020:03:03

and hopefully push a little more warmth

0:03:030:03:05

back in across us.

0:03:050:03:06

All the time, though,

0:03:060:03:07

across the far north and east of Scotland

0:03:070:03:09

and north-east England,

0:03:090:03:11

you're staying on that colder side of the jet -

0:03:110:03:13

but it looks as though

0:03:130:03:14

further ahead will be a little less changeable,

0:03:140:03:16

though the best of the drier weather

0:03:160:03:18

will be in the south -

0:03:180:03:19

and hopefully, fingers crossed,

0:03:190:03:21

something a little warmer

0:03:210:03:23

returns for many of us.

0:03:230:03:24

More from me same time tomorrow.
