05/03/2017 Weather for the Week Ahead

Hello, thanks for joining me, it's that time where we try to

give you a sense not only just of what's going on in the next few days

or so, but we give you a sense of what's likely to be going on

as far ahead as the forthcoming weekend.

Over the next few days, the

jet stream will be powering areas

of low pressure towards the British Isles.

There's no great meander in

the jet just at the moment.

It is very much a direct line

from what's going on across in the

eastern side of the USA to

us here in the British Isles.

And when we get that sort of set-up, well, it is that sort

of time of year where we keep the unsettled weather coming.

There will be some blustery winds and some spells of really

quite significant rain at times as well.

The first of those perhaps manifesting itself across the

southern half of Britain

in the first half of Sunday.

At least it's on the move so

after a wet start across the

south-western quarter, it gradually

drives its way towards Wales,

The Midlands, East Anglia and parts of

the south-east with blustery

showers following on behind

and pretty strong winds as well,

50/60 mile an hour gusts for a time.

But the good news of the day is

that it's a much improved picture

across Scotland, Northern Ireland

and the north of England.

There will be some sunshine

and the persistent rain largely saved

for the Shetland Isles.

Now, as that system tends to drift away,

it only makes room for another

one in the first part of Monday,

just to give a glancing blow into

the south-western quarter of the British Isles.

But in its own right,

that will be another spell

of rather wet and windy fare.

Monday elsewhere, a sort of

in-betweeny sort of day, not an

awful lot going on, quite a bit of dry weather around,

some brightness, the bulk of

the showers to be found across the northern and

north-western parts of Scotland and

indeed, Northern Ireland.

Now the isobars just start to

ridge from Monday into Tuesday.

More settled conditions,

what a pity much of that comes in

overnight from Monday to Tuesday

which will be quite a chilly night

and then we'll again be

looking towards the Atlantic to

see the next spell of pretty wet

weather piling its way in

towards Northern Ireland and eventually

the Western fringes of

Scotland, Western England and through Wales

with the very best of the weather to be found

through Tuesday away towards the east.

Until the fronts come to get you even here.

But at least the frontal systems

clear away for the most part

both into the north sea and down

into the English Channel

although that's quite a close

run thing so there'll still be

a lot of cloud on Wednesday here.

Looking further north, that low

pressure not a million miles away.

Some pretty strong winds in that circulation across the

north-western quarter of Scotland.

We're probably talking gale force winds and

so a blustery day elsewhere and

then we get into the latter stages

of next week and there is some

uncertainty about the overall

message here but we suspect,

as I was intimating earlier,

that the jet stream will be firing

those low pressures close by

to the north-western quarter

of the British Isles with

high pressure trying to hang on

down in the south-western quarter.

Now, as far ahead as next weekend,

this could be the scenario.

Low close by to Denmark,

high pressure away towards the south-west

and that will leave us with

a north or north-westerly flow,

never a warm direction at this time of year.

The outlier solution in models at

the moment is that we could have

a low pressure close to the English Channel with high pressure

a little further north

and that would suggest an east or

north-easterly, again, never a warm

direction and you may well say,

"Well that's just a little bit of a

"nuance, a little bit of a subtlety,"

but it does mean that whatever model

wins out, things will turn colder,

it will be a windy week and it will

often be really quite unsettled.

Bye-bye.
