27/05/2017 Weather for the Week Ahead

Hello, there. It's almost as if the weather knows

it's a bank holiday weekend upon us,

because the devil is the detail this weekend.

We're into the breakdown of the heat. The heat peaked on Friday.

The highest temperatures of the year so far - 29 degrees,

not far short of 30, at Lossiemouth -

but that'll be the hottest I think we'll see

during this spell.

Still some heat around on Saturday,

still some thundery showers making their way eastwards

across England and Wales through the morning hours,

and some of them with thunder and lightning.

Wetter weather, potentially,

for Northern Ireland and parts of Scotland -

and then, when you add the fact

that we've still got that heat and humidity around, with us,

we will have some lively downpours into the afternoon.

From the Midlands northwards, torrential thunderstorms

with large hail and some flash flooding, potentially.

Sea fog in the North.

Not that many showers in the South, come the afternoon.

It will feel cool around the coast.

We could get 28 degrees,

so, not far short of what we had on Friday,

but the heat is starting to diminish,

and it will gradually - or, we will gradually -

see those thunderstorms petering out through Sunday night.

We keep some rain going, and temperatures are still high,

but not as oppressive as it has been,

and not as oppressive, I think, as it has been this week.

So, that area of low pressure responsible

for that first spell of thundery rain

moving out of the way during Sunday.

High pressure builds in behind it for a time,

so, not a bad day, really.

There'll be more cloud around,

it will feel a little cooler and fresher in the north.

We'll still have the heat in the South, and the humidity,

so, we'll start to see some home-grown thunderstorms here,

and then, later in the day,

we could potentially start to drag some more thundery rain

across from France, across the Channel, and northwards.

It looks as if it will be across the southern half of the country,

but there is some uncertainty

as to how far north that thundery rain will travel.

Some of the models do push it right the way up into northern Scotland.

So, at this stage, there are warnings out.

We will tweak those, of course, with time.

It does look as if we'll get off to a thundery start.

Thundery night,

some thundery weather around, still, on bank holiday Monday,

a lot of heat and humidity,

a little bit fresher further northwards,

but, of course, that could extend its influence further north.

Come Tuesday, it should have moved out the way,

and then we're under the influence of Atlantic weather fronts.

So, we've changed the wind direction.

It does freshen up even further south and east by that stage -

it will still be warm, in the sunshine,

and there still will be some sunshine,

because high-pressure follows that weather front on Tuesday,

and that high pressure's with us through the middle part of the week.

It's keeping the weather fronts at bay,

it's allowing the temperatures to rise and the sun shine again.

Not the humidity that we've had this week,

but, nevertheless, some strong sunshine,

and feeling very pleasant

if you are in that sunshine out and about.

Of course, it's half term for many,

so, some very usable whether

through the course of Wednesday, Thursday, Friday, as well.

So, the early part of the week is seeing that high-pressure

starting to take hold once again,

keeping those low pressures at bay out in the Atlantic -

and there's a little bit of a southerly breeze with it,

so, we will see things warming up,

but it's definitely fresher than it has been.

However, as we progress through the latter part of the week,

head towards next weekend,

we'll start to see that high-pressure

just drifting a little bit further southwards, towards the continent -

always keeping an influence across southern areas,

but allowing low pressures to bring in bands of windier weather,

wetter weather,

but probably not that much rain in southern and eastern areas.

Just because that high-pressure is so close by,

it will mean that those weather fronts tend to weaken

as they progress further southwards and eastwards.

Nevertheless, it does look more unsettled by that stage,

by the end of next week, and it will start to feel fresher -

but the detail for the weather for the weekend,

there's more on the website.
