24/04/2017 Weather for the Week Ahead

Chilly weather looms.

In fact, Mother Nature is about to remind us that winter was

not that long ago.

Certainly, a dose of winter on the way for some of us early this week.

But it's not going to be that cold.

We're not expecting drifts or deepfreeze necessarily,

it's just going to feel really chilly.

Don't forget, the sun is very strong this time of year,

so actually, it's very difficult to get especially

low temperatures towards the end of April.

It's if you're caught in the shower clouds, if you're in the shade,

if you are having a walk down the seafront -

for example, the North Sea coast -

that's where it's going to feel on the chilly side,

and you will need your thick coats, possibly hats and gloves as well.

This cold front here that's set into motion, that is the cold front

that will be introducing that colder air from the Arctic.

On Monday, we're still just about hanging on to some of that

milder weather across the South.

But look at the wintry showers affecting Scotland,

the south of Scotland, possibly the north-east of England as well.

And then into Monday, that colder air will have reached areas

as far south as northern France.

Then on Tuesday, we're well and truly in this cold blast of air.

And it will be wintry showers hail, showers,

particularly across these northern, northeastern

and eastern areas of the UK.

But also inland there'll be some wintry showers around.

Most of us will probably get sunshine, the occasional shower,

big storm clouds like this, possibly even a hailstorm.

And if any snow does fall during the daytime,

it's most likely to settle across the hills

rather than in our gardens, if you live in towns and cities.

So, actually, for many of us,

it will be quite a sunny day on Tuesday, but a chilly one.

Those temperatures really will struggle.

As we head into Wednesday,

high pressure starts to build off the Atlantic,

but with winds blowing like so, we still have northerly winds.

So the source, where the air's coming from, is still pretty nippy.

So again, another chilly day,

but I don't think it's going to be as cold as Tuesday.

Still showers around on Wednesday,

and those temperatures struggling, single figures for many of us,

just about double figures across southern parts of the UK.

Look what happens by the time we get to Thursday.

This colder Arctic air, which would have originated from the north,

of course, is squeezed out, cut off,

once this milder air starts racing in off the Atlantic.

The transition will happen from Wednesday into Thursday,

we'll see a switch in the wind direction,

and that milder air will start toppling over the UK.

But it still will be a fairly cloudy day, and for some of us,

no doubt, it'll feel on the chilly side.

And then towards Friday, I think the weather's looking

a little bit more like normal.

We'll start to see weather fronts lining up in the Atlantic,

heading in our direction, and there probably will be some rain

heading towards parts of Scotland.

Let's take a look at the jet stream as we head towards the weekend.

This is probably very early in the weekend, sometime Friday night.

Very quickly, this jet stream, with the low pressure sitting here and

the unsettled weather and rain,

that jet stream will push its way towards the east.

So around Saturday/Sunday, that dip in the jet stream,

with the low pressure, will be over us,

and we're expecting unsettled weather.

So the weekend is looking unsettled, next weekend.

Then very quickly, the thinking is that dip in the jet stream

with the low pressure will push towards the east,

then we'll start to see high pressure building

and things will settle down.

So, early next week, it looks like the weather will dry out

and it should be fairly pleasant. Bye-bye.
