26/05/2017 Weather for the Week Ahead

Hello. With a bank holiday imminent and for many next week's half-term,

please don't make this the last forecast you see,

because the details will differ a little from day to day,

with a thundery breakdown on its way.

No surprise, because we've had the heat on Thursday,

temperatures got into the '80s Fahrenheit quite widely.

We saw temperatures in the high 20s, and Friday will be no different.

We start with a little bit of sea fog and some mist

but it takes no time at all to clear,

and then it's basically a repeat performance,

although we will see somewhat cloudier skies

coming in towards the west of Ireland later on.

But again, 25 to 29 is on the cards.

It will be a very hot day indeed for many, except on windward coast,

but even here, UV levels will be high,

and unusually, very high levels of UV are forecast again on Friday

in southern areas.

Then we start to see that change.

Now, the detail will be quite difficult

with this thundery breakdown, as it always is,

but it looks as though we'll see those thundery showers

coming in to the South-West and Northern Ireland,

so a really quite uncomfortable night,

because obviously the humidity will be a lot higher once again

with all those showers falling.

So yes, it is a hot and humid start to our bank holiday weekend,

but that thundery breakdown will occur gradually,

different areas, if you like, at different times,

before it finally freshens up.

So for Saturday, it looks as if we'll start with the showers

running across parts of England and Wales

but perhaps stagnating a little more across parts of Northern Ireland

and then Western Scotland,

so it really could be quite a wet day in these areas.

Some quite severe thunderstorms are forecast,

but ahead of it there'll be some very nice weather, and behind it,

as it freshens up, as well, some decent sunshine will come through.

So it's not a wash-out, although it doesn't look particularly pleasant

for much of the day in Northern Ireland

and western and southern Scotland. It's still hot,

we've still got some humidity around to break down. So those storms

will continue to rumble on through Friday night into Saturday

before pulling away. High pressure starts to build then

but we've got this next area of low pressure coming in to the south,

so it could be that we see a second thundery breakdown,

this time more likely across the southern

and eastern part of the country.

Later in the day on Sunday and into Sunday night

it looks very thundery indeed, at the moment.

Of course, by that stage, it's freshened in the north

and it's a slow improving picture as high pressure takes over,

but not in the south. This is Sunday night and into Monday.

It looks like we could have

some really torrential downpours once again,

some large rainfall coming down from those intense storms.

And they will take a while to clear away.

Still a lot of heat and humidity left around, even into Monday.

These temperatures are probably quite conservative,

we may see a few degrees higher than that, actually,

where the sun comes out for a long time. And it should do,

with high pressure around across many areas.

Still, though, that weather front with us

across the eastern side of the country even into Tuesday

before we finally start to see that thundery weather clearing

out of the way, and then we will see a few scattered showers elsewhere,

and temperatures back down closer to normal.

I think for most of the week

they will stay above where they should be for this time of year,

so more strong sunshine coming through.

And with high pressure building from the midweek onward

it looks set fair. It won't be as hot as it's been this week,

but pleasant enough, until late in the week.

And this is where we think we'll get back to

a more mobile weather pattern as we head towards next weekend,

when the low pressures

start to usher in weather fronts from the Atlantic.

That's when we'll see rain at times,

but initially, midweek it will become settled and quite warm again,

but there's that thundery breakdown before then.

And as ever, you can get more on the website.
