25/04/2017 Weather for the Week Ahead

It is going to be a cold and frosty start to Tuesday.

Not just frosty, but for some there is likely to be some wintry weather

particularly in the north and north-east of the UK.

In fact, that is what we saw on Monday, some snow showers

giving a covering of snow in some parts of the north of Scotland.

Not unusual this time of year to see some snow, but certainly unwelcome.

That is what we're going to see in the north and north-east

through the morning. Cold in the wind as well.

After a sunny start elsewhere, cloud will build and we will see

some pretty lively showers going into the afternoon.

Showers in Scotland will contain some snow mainly over high ground.

Some might get down to lower levels at times and it is cold in

the wind in spite of some sunshine.

Similar in Northern Ireland. There will be some hail,

some thunder and showers across some parts of England and Wales.

When you get the hail showers,

you also get some really cold winds coming down from those clouds,

down draughts which could drop temperatures by several degrees.

But get back into the sunshine

and out of the wind it will be not too bad.

Still further wintry showers around through the evening mainly towards

the north and east of the UK.

Further west, we have got clearer skies and the blue tinge,

that is a touch of frost developing.

I think generally it will be a cold start to the day on Wednesday.

Single digits across the board.

Probably below zero in a few places.

We've got high pressure in charge on Wednesday.

The winds go clockwise around that.

Still the air is coming down from the Iceland region

so not particularly warm but still some dry and bright weather

to be had. Where it starts quite cold in the west, some spells

of sunshine here, but further east we're likely to see some

showers getting going and there is a risk of some hail and sleet.

But some spells of sunshine further west.

Although in the north-west, we'll see some thicker cloud and some

outbreaks of rain just fringing in here.

Six degrees in Shetland, 12 degrees in London.

The average is around about 9 through the middle of the week.

But the general trend is for those

temperatures to keep on rising day by day

so the highest temperature will be coming in just after

the bank holiday weekend. Those are average temperatures.

Some will be a bit higher, some a bit lower.

As you get on into Thursday,

we've still got high pressure in charge of our weather.

This weather front will be fairly weak as it drifts its way south

but it will bring a fair bit of cloud with it and some rain.

Not a great deal, but some.

I think the south-east is going to stay driest for longest.

That is why will see the highest temperatures -

around about 13 or 14 degrees.

But not too bad in Glasgow, it is around about 12 degrees.

Then as you head on towards the end of the week, still got high pressure

in charge, still got a weak weather front drifting its way south.

Not much rain to be had from that by this stage but still

a fair bit of cloud, maybe a bit of rain in one or two places but

a lot of dry, rather cloudy weather towards the end of the week.

12 degrees in Glasgow is not so bad, 13 or 14 in Cardiff and London.

Then as we head on into the start of the weekend,

high pressure is centred over Scandinavia,

still exerting its influence across the United Kingdom

bringing a bit of a breeze from the east and that will drag in

a fair bit of cloud, but not much rain to speak of.

Around about 14 or 15 degrees in the south-eastern corner.

Then on into the bank holiday itself,

question marks about the details.

One scenario is that high pressure is to the east of UK which means

the weather systems could well cross our shores bringing some rain

mainly towards the north and west.

However, if that high is a little bit further west its influence

may well just break up those weather fronts

so there is very little rain to speak of.

So there are some question marks about that.

However, after the bank holiday it looks like things

are going to be quite unsettled in the north-west, drier and brighter

in the south-east. Generally speaking becoming warmer.

The question is how warm will it get? It could get very

warm for some of us, mainly in the south-eastern corner.
