24/01/2018 Weather for the Week Ahead

If you've been with me in recent days you'll know that we've got

a degree of certainty about what's going to go on in the next few days.

It's the outlook period in which we have just a degree of uncertainty.

What I'm very sure of in the short term is that Wednesday

is going to be very much about the influence of

Storm Georgina, the next named storm in the season sequence,

which will be a real player across the northern parts

of Scotland. We'll all feel the wind from that feature

and then there's this front to contend with as well,

gradually slumping its way right across the whole of

England and Wales.

There sits Georgina, very close to the Orkneys,

as we start the afternoon. Notice the strength of the

gusts here. Widely across the northern half of Britain

we're looking at 40, 50, 60mph or so at the very least.

As we come that little bit further south, even in inland

areas behind the weather front, yes, it brightens up

but it stays pretty windy - 30, 40mph gusts.

Anywhere near that weather front and it remains very squally.

That front eventually pushes off into the near continent

and Georgina moves off towards Scandinavia, leaving

behind another little area of low pressure. The wind

around this still pretty strong but nowhere near as strong

as they will be during the course of Wednesday.

A day on Thursday of sunshine, especially in the

south-eastern quarter. Elsewhere I think you're in with

a pretty fair chance of seeing some blustery old showers.

As we close out the week that area of low pressure rather

fills in situ. Notice how the isobars by this stage

have come right out of the south-west and there is

more of a north and north-westerly about proceedings.

That's a pretty cool direction. The last of the shower activity

there across eastern shores, temperatures in the

range of 4 to about 8 or 9.

That'll be the last of the cool days, I would have thought,

simply because as we get towards the weekend look at

where the air is coming from -

up and around this high pressure and then bumping into the

British Isles. A long sea track carrying a lot of moisture

which means a lot of cloud and there will be a weather front

to thicken up that cloud across western parts.

There isn't a great deal of difference as we move on

into Sunday. That high pressure trying to influence things

across the southern half of the British Isles,

but it just runs out of influence as we get towards the

northern and western parts of Scotland, particularly

here some more in the way of cloud and rain but look at

the temperatures - they're back to the sort of values

that many of us saw during the course of Tuesday.

As we start the new week I think we'll still be influenced

very much by this feed around the high pressure of

milder airs coming in from the Atlantic to dominate

many parts of the British Isles,

perhaps not just the far north of Scotland,

because there we've got some fresher conditions.

The boundary between those mild airs and the colder air to the north

usually means some fairly strong winds. That'll be the way of it

across northern parts of Scotland.

We think the high pressure is going to settle down towards the

south of the British Isles, with that mild feed of airs,

which generates quite a bit of cloud.

However, if that high pressure

were to drift up to the

western side of the British Isles

we then end up with a fairly cool

northerly to north-westerly flow

across the British Isles

and that will give us a different look and feel to the days

across many parts of the British Isles.

It would be brighter but it would be that wee bit cooler.

So, we think the driest of the conditions will be found to the

south, with some mist and fog

and frost around,

it'll be wet and windy in the north.

But as I say, there is

a degree of uncertainty.
