Hello. The week ahead is a story of ups and downs weather-wise.
The temperatures at the moment are certainly on the up.
Monday brought a lot of sunshine.
A beautiful day for the beach
on the Moray coast
in north-east Scotland
and also there in Cornwall.
Notice, though, a bit of high cloud
gathering in the sky.
Just the first sign of some changes
that are going to take place later in the week.
As those temperatures continue to rise,
the middle part of the week is likely to bring
some quite vicious hit and miss thunderstorms.
Once those clear away,
the temperatures head downwards again.
Some cooler, fresher conditions to take us towards the weekend.
For the time being, though, high-pressure is in charge.
As the high-pressure drifts a little bit further eastwards,
it allows us to bring in this south-easterly airflow
and that taps into some very, very warm air indeed
across the near continent, some pretty humid air as well.
So Tuesday will bring increasingly humid, muggy conditions
and some more of that high cloud just
streaming its way in across England and Wales.
Having said that, there will still be a fair amount of sunshine
although some thunder storms late in the day towards the south-west.
An easterly breeze off the North Sea making it feel a little bit
chilly along the east coast,
but inland and further west,
temperatures up into the high 20s in places.
And with that heat and humidity, we will start to see some
thunderstorms spreading in from the south during Tuesday night.
They will be quite hit and miss but if you catch a storm,
it could give you a lot of rain in a short space of time.
Frequent lightning, maybe some hail.
Some of those storms continuing across Scotland during Wednesday.
As it brightens up across England and Wales,
there could be enough heat
and humidity to drive some further thunderstorms here and there.
But, by this stage,
something fresher beginning to show its hand out west.
Through Wednesday night, into Thursday,
as this cold front sweeps its way eastwards,
it will start to bring us fresher air from the Atlantic.
So westerly winds across the country on Thursday.
A bit of a humid start, perhaps, across the south-east.
By the end of the day,
those temperatures much lower for all of us.
A lot of dry weather, but some showers up towards the north-west.
As we head into Friday, it looks like an area of low pressure
will drift in from the Atlantic.
A band of rain with that.
So a bit of uncertainty about the timing of this rain band,
but there will be some spells of wet weather for many
and even where the main band of rain has cleared away,
there could be some further showers.
But the temperatures are way down on where
they have been - 15 to 21 degrees.
Low pressure still dominant as we move into the start of the weekend.
The low likely to be across northern Scotland.
There will be some spells of sunshine, also some showery rain.
These westerly winds continuing to bring us the fresh conditions -
16 to 22 degrees.
The areas of low pressure will be brought
to our shores by the jet stream -
the winds way above our heads that drive the weather
systems around the world.
But notice as we go through the weekend,
it looks like we could see a change in the shape of the jet stream.
It is likely to bend its way northwards. What does that mean?
Well, it means an area of high pressure that
sits down across the Azores,
may well be able to nudge its way a little
bit further north and east and have a bit more influence on our weather.
But there is some uncertainty into next week just how far north
and east this area of high pressure will exert its influence.
And in northern parts of the country,
there'll be a fairly unsettled flavour.
Spells of rain, quite breezy.
But further south,
it should become mainly dry, pleasantly warm,
but not as warm as it is at the moment.
