05/07/2017 Weather for the Week Ahead

Hello. Thanks very much indeed for joining me.

It's that sort of time where we try and give you some detail

about the next five days or so.

That'll take us right on into the weekend.

And then, from there on, we try to give you some sense of the trends.

Before we launch ourselves into the future,

a quick resume of Wednesday.

A day of marked contrasts.

And overnight, those temperatures really not changing

across the northern half of the British Isles

and quite a sticky night to come across the south.

Some areas never lower than 17, 18, 19.

And when the temperatures stick at those sort of values,

put a little bit of moisture to some levels in the atmosphere,

and we end up with this...

Thunderstorms right from the word go, perhaps,

across the south-eastern quarter of the British Isles.

All the while, further north, a frontal system just bringing in rain

initially to the western side of Scotland, but becoming more patchy.

Through the course of the afternoon, if things come together,

those thunderstorms could give us torrential downpours

anywhere from the eastern side of Wales

to the north-east of England

on what is going to be another very hot day,

with some of that heat getting up towards the north of England,

always that bit cooler for Scotland and Northern Ireland.

If those thunderstorms come to pass,

they could give some very tricky driving conditions indeed,

torrential downpours, a lot of surface water,

before they gradually creep away off into the North Sea

to leave behind Friday.

A definite in-between sort of day.

If you're not that close to that weather front across the north,

then I think you are in for a dry day.

Don't worry about the frontal system out in the Atlantic too much,

I think that is going to be more of a player

late in the day in the western side of Ireland.

So make the most of the sunshine,

strong at this time of year, of course,

even with the cloud filling in, 28 to 29 in the south.

Perhaps the north of England a fraction cooler

than was the case on Thursday.

The north of Scotland well on into the teens.

Friday into Saturday, rather like Tuesday.

You'll certainly remember Tuesday if you were in this same zone,

because it was a particularly wet day.

And I think Saturday, yes, it starts very wet,

then the rain begins to ease

and the last of what we'll call this week's heat

is still there to be had across East Anglia and the south-east.

Now, Saturday into Sunday.

Sunday looks a bit of a write-off first thing,

simply because we've got low pressure with frontal systems

down to the south-east, another set of fronts in the north.

While I'm hopeful that much of the thunderstorm activity

associated with the front in the south-east

will stay in the near continent,

maybe the odd shower getting a little bit further east,

and those fronts tending to weaken in the north all the while.

Come Monday, no signs of heat at all,

because the isobars are bent around into the north and north-west,

so a fresher feel right across the British Isles

and disappointing fare if you happen to be on holiday.

That's not what you want to see.

It'll be a mixture of the odd sunny spell,

but quite a bit of shower activity.

And then the trend develops into next week.

High pressure tries to build in,

giving us the sense of something July like.

But in the middle part of the week it may well be

that an area of low-pressure swings frontal systems in,

a lot of cloud and the odd bit and piece of rain,

especially in the northern half of the British Isles.

But there is nothing settled about this battle,

because it could well be that later in the week

the high pressure resumes its dominance,

certainly in the southern half of the British Isles.

And we could well see a return to more glorious conditions.

So you get the sense that next week could well be a moveable feast

of weather, changeable certainly, with the wettest of the weather

across the northern and western parts of the British Isles,

perhaps the warmest always to be found in the south-east.

More tomorrow. Bye-bye.
