06/11/2017 Weather for the Week Ahead

You may have to concentrate over the next three and a half minutes

because there is an awful lot going on with our weather

through the next seven to ten days - plenty of twists and turns,

lots of changes on the way

and, as we start off the new working week,

a chilly start for many areas,

particularly central and eastern areas

under the influence of this ridge of high pressure.

Frontal systems trying to muscle in

from the north-west,

but taking a time to work eastwards

so really it'll only be north-west Scotland

that seems some heavy rain during Monday,

extra cloud and some patchy rain

into other western areas.

After a frosty start,

any early fog clearing quickly

and then some sunshine further east,

but just 9 degrees in Norwich,

temperatures creeping up

a little bit there in Belfast

and as we head through Monday night,

our frontal system

will eventually make some progress.

Heavy rain sweeping through Northern Ireland,

a good part of Scotland.

Notice some of the rain turning to snow

over the high ground in Scotland,

western fringes of England and Wales

and a significantly milder night,

a significantly milder start to Tuesday morning.

So, here's our frontal system, then,

drifting eastwards.

Ahead of it, some pretty strong winds.

Behind it, some cold air tucking back in

so, as I mentioned, some of the rain

across the high ground of Scotland

will turn to snow.

This band of wet weather

working quite erratically eastwards

through the day on Tuesday.

Windy ahead of it, lighter winds behind

and with some sunshine returning,

some showers into the west,

hefty showers at that,

but in western areas,

it'll be cooling down again -

9 degrees in Belfast,

perhaps getting up to 12 there in London.

As we move through the middle part of the week,

this little area of high pressure

tries to have more of an influence on our weather

so Wednesday is a window of quiet weather.

Now, at this time of year,

quiet weather often means frosty mornings

and I think that's what we'll see

on Wednesday morning.

Could be some fog patches, too,

but then a decent day with spells of sunshine

before our next change pushes in from the west.

Another frontal system

drifting its way through,

bringing some outbreaks of rain.

Now, there is some uncertainty

about the timing of this,

but it looks like this will be out of the way

from most places by the start of Thursday morning.

It will hang around in the south-east, we suspect,

for a while and then as it clears,

we're back to sunny skies.

It will be windy, though,

particularly in the north

and there'll be a cool feel

with temperatures of 9 to 13 degrees

and some showers into the north-west.

Now, as we get into Friday,

there is a lot of uncertainty

by this stage, I have to say.

High pressure will still be not too far away,

but frontal systems again

pushing in from the Atlantic.

We could see outbreaks of rain

just about anywhere on Friday,

perhaps turning just a little bit milder

down to the south, 13-14 degrees,

but on the cool side across Northern Ireland,

northern England and Scotland.

So, that particular frontal system drifts away.

We get the ridge of high pressure coming back

so another quieter interlude

and then Atlantic weather systems

try to drift in again from the north-west

and that is the pattern that takes us

through the coming weekend and beyond.

Areas of high pressure getting closer

and then drifting further away

and as the high drifts away,

it allows low pressure systems

to move in from the north-west.

Now, when our unsettled weather

is coming from the north-west,

it will always be northern

and western parts of the country

that see the heaviest

and most persistent rain.

Further south and east,

there'll be a bit of shelter

so, yeah, there'll be some rain,

but the rain not especially heavy

for much of the time.

And there is a chance that, at times,

our area of high pressure

will settle close to the British Isles

for a little bit longer

and if that happens,

we will get some slightly longer,

drier interludes. If that happens, though,

we'll also see some frost and fog

so a lot going on through the week ahead.
