24/06/2017 Weather for the Week Ahead

Hello there. Our weather has gone back

to something you might call normal

as we head towards the weekend, certainly compared

with the exceptional weather we had earlier this week.

Exceptional heat,

where some spots got very close to 35 degrees Celsius.

For the weekend, 20 will be more typical.

Some places will be even cooler than that

and it's quite a mixed weather story, really.

Some sunshine, some showers, it will be breezy and fairly cool,

certainly compared with what we've had recently.

Now, an area of low pressure

is moving across the north

of the British Isles at the moment.

Actually quite a deep low.

You can see tightly squeezed isobars

and that's going to make for a windy Saturday

across parts of Scotland.

Also a weather front dragging its heels

across England and Wales

so here through Saturday,

fairly large areas of cloud.

Some outbreaks of patchy rain at times,

should brighten up a bit towards the south-east.

For Northern Ireland and Scotland,

we'll see some sunny spells,

a few showers,

but very windy across Scotland.

We could see gales in places

and it is going to be a cool day.

14 to 18 degrees in the west,

maybe 22 or 23 in the south-east.

Now, during Saturday night,

the weather front that will have been

plaguing the south with a lot of cloud,

that will clear away

and our area of low pressure to the north

will slide its way eastwards

so Sunday should bring

slightly lighter winds across Scotland.

Still quite blustery here.

A mixture of sunshine and showers for most,

although it will be fairly cloudy again

across some southern areas

and those temperatures,

you'll be lucky to get to 20.

16 in Glasgow,

maybe 23 across parts of the south-east.

Now, some humid air may return for a brief time

as we head into the start of next week.

It's been pulled up from the south

by this warm front

ahead of an area of low pressure so for Monday,

there's going to be a lot of dry weather

around in many areas,

but we're likely to see some outbreaks of rain

pushing in from the west.

There's a bit of uncertainty

about exactly where the wettest of this weather will be.

Certainly a fresh feel up to the north-west,

but something a bit more humid down to the south

and during Monday night into Tuesday,

there is a chance we could see

some really heavy thundery downpours

pushing up from the south,

brought in by that humid air,

but it won't be around for long

because, as those heavy downpours

clear away to the east on Tuesday,

we'll start to bring fresher air

back in from the Atlantic.

Now, that brief flirtation with some humid air

comes because of this dip in the jet stream.

We briefly get onto the southern

and eastern side of the jet,

where the humid air lurks.

But as the jet stream breaks back through again

and moves straight across the Atlantic

through the middle part of the week,

we'll be on the northern side of the jet.

That's where the cool air sits

and we will be in that cool air

for the middle of the week.

The jet stream also spinning up areas of low pressure,

which will keep things

quite unsettled through Wednesday

and, indeed, on into Thursday.

So for the middle part of the week, then,

our jet stream will be working

straight across the Atlantic,

keeping us in the cool air

and bringing us further areas

of low pressure, but there is just a hint

in some forecast weather models

that by the end of the week,

the jet stream might take on

more of a bendy appearance

and, yes, that will initially

keep us in the cool air,

but will bring some warmer air

slightly closer to southern areas

and with it, potentially a build in pressure,

high pressure trying to edge its way in

towards the south.

It's going to be a slow old process, though.

Essentially for the start of July,

it is going to remain quite cool.

There'll be some rain at times,

but some sunshine, too,

but just hints that we might see

something more settled and perhaps warmer

a little bit deeper into the month.

But for the time being,

we're back to normal.
