16/06/2017 Weather for the Week Ahead

Hello there. So far, this week has been relatively quiet and,

in actual fact,

the weather patterns that we have had have been stuck in repeat and,

in fact, Thursday's Weather Watchers illustrates this beautifully.

The north-west again cloudy with outbreaks of showery rain

through the afternoon in Scotland but,

into the south-east corner across that Kent coast,

we had an early afternoon high of 25 degrees, 77 Fahrenheit.

This band of cloud, though, was a weather front.

A weak affair, it brought more cloud as it pushed south and east, and it

introduced fresher air following on behind and a scattering of showers.

That's going to be the theme as we run through Friday.

A change to hotter weather returning as we move into the weekend.

But, for the bulk of Friday, central and southern areas dry and sunny.

The south-westerly breeze just driving in

a little more cloud and some drizzle and mist across the far north-west

but, with some brightness,

we could see highs of 20, 21 degrees here,

23 not out of the question in the south-east corner.

As we move out of Friday into Saturday,

things stay relatively quiet and, in fact,

for the start of the weekend,

that high pressure stays with us across England and Wales,

all the time just seeing these weather fronts toppling

through the top and still producing that breeze,

that drizzle and also some misty, murky conditions on the coast.

So we start off on Saturday on a mild, murky note to the north-west.

Lots of sunshine further south, and that is just going to allow

those temperatures to climb quite quickly on Saturday,

and the humidity starts to build.

So, by the middle of the afternoon, we could potentially see

temperatures mid to high 20s not out of the question.

Little bit fresher where the cloud and the breeze sit to

the north-west of the Great Glen in particular.

Spot the difference as we move out of Saturday into Sunday.

Still the high pressure in the driving seat across

much of England and Wales.

Still that weather front trailing across the top,

but the heat will continue to build.

On Sunday, potentially somewhere in the south-east could see

highs of 29 or 30 degrees, and it really will start to get

quite humid and feel uncomfortable out there.

High UV levels as well - that's worth bearing in mind.

As we move into Monday, it still stays hot, but just watch

this area of low pressure trying to build from the south-west.

So, on Monday, we still could get high 20s, possibly into 30 degrees.

And perhaps the rain not as significant in the far north,

but that north-easterly breeze just making it feel on the chilly side.

By the time we get out of Monday into Tuesday, we continue to see

that north-westerly breeze, so it will be chillier in the far north.

At the same time, we could, with that humidity,

see a few isolated but sharp thundery downpours

develop into the south-east,

and that's going to be the trend into the longer 6-10 day period.

A lot of uncertainty about looking ahead.

But this is the scenario at the moment.

An area of low pressure moving into the south-west could trigger off

some thunderstorms which will drift further north.

Some of those could be heavy and possibly thundery.

Now, that low will eventually move north-west,

amalgamate with another low, potentially pushing in from

the Atlantic, and then we're back to this north-westerly pattern

with the low up in the north-west and high pressure dominating

down to the south, which basically means we see

a return to cloudier, more unsettled breezy conditions to the north-west.

The best of the sunshine and the heat in the south but, again,

as the humidity builds,

that could potentially trigger off some sharp and thundery downpours.

As I say, a lot of uncertainty about the 6-10 day period.

We'll firm up on those details tomorrow.
