11/07/2017 Weather for the Week Ahead

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

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

yesterday we saw a high of 27 degrees,

but by Tuesday temperatures will be significantly lower.

20, 21 degrees, if we are lucky -

and there will be, at times,

some heavy and some persistent rain to come.

It will start off light and showery

across Wales and south-west England,

but then this area of low pressure

will move in and just enhance that rainfall

as we go through the day.

So, perhaps the best of the weather

on Tuesday is likely to be

across Scotland and Northern Ireland,

with just a scattering of showers.

Some patchy rain to begin with

in the south-east,

maybe a brief lull through lunchtime,

before some more heavier persistent rain

pushes into the south-west,

and we'll see the winds strengthening.

Just how far north that rain goes

is still open to question -

but look at these temperatures.

Significantly down on what we've been used to.

14 to 20 degrees at the very best.

Now, as we move out of Tuesday,

that rain still yet to clear away

from the south-east corner -

so, welcome news for gardeners and growers.

Some much-needed rain

across much of central and southern parts

of England and Wales -

but behind that low,

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

to a northerly or a north-easterly direction,

making it feel just that little bit fresher

on those exposed east coasts -

but on Wednesday a quieter day,

drier, with sunny spells coming through,

temperatures at around 16 to 22 degrees,

feeling a little better the further west

in a little more shelter.

As we move out of Wednesday,

we see this ridge of high pressure building,

so, things quieten down

for a day, at least, again.

We'll see this weak weather front threatening,

so, the best of the weather on Thursday

is likely to be across sheltered eastern areas.

Dry, with some sunshine, a scattering of showers

developing out to the west

as we go through the day.

17 to 23 degrees the high

by the middle of the afternoon.

Now, that weather front has yet to clear away.

It will do so during Thursday

into the early hours of Friday morning,

and will bring some showers with it

before, again, another ridge builds,

before the next system

waits in the wings across the north-west.

It's going to stay pretty changeable this week.

So, we could have some early showers

across the south-east corner

to clear away first thing on Friday.

Drier, brighter weather from the west,

before the next area of frame starts to show its hand

into the north-west by the end of Friday.

That will bring some wetter weather,

weakening all the time

as it pushes steadily east -

but for the start of the weekend,

stays pretty changeable.

It stays pretty windy at times,

and there will be some showery outbreaks of rain,

so, it's not all straightforward

for the start of the weekend.

Top temperatures around 18 to 23 degrees.

It probably won't come as a surprise to hear

that the jet stream

is sitting right across us at the moment,

allowing for this mobile westerly flow,

for the Atlantic frontal systems

to move in from day to day -

but, as we move out of the weekend

into the longer-term period,

it looks as though we'll see

more of an amplified jet stream,

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

from the south-west,

and hopefully push a little more warmth

back in across us.

All the time, though,

across the far north and east of Scotland

and north-east England,

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

but it looks as though

further ahead will be a little less changeable,

though the best of the drier weather

will be in the south -

and hopefully, fingers crossed,

something a little warmer

returns for many of us.

More from me same time tomorrow.
