23/01/2018 Weather for the Week Ahead

Hello. I'm going to give you a fair amount of detail how we see

the rest of the month panning out across the British Isles

and then we'll just take a quick look on some of the themes

we think are going to develop in the first part of February.

The coming week - bit of a mishmash, not unusual for January.

A milder start, but as we close out the week, I think

things briefly will turn cooler.

Maybe not as cold as we've had it,

but certainly cooler than the start of the week.

The reason why it's going to be so mild to start off

is that we've got this run of south-westerlies.

Quite a bit of breeze, notice the number of isobars, notice that we

also have two fronts lurking with intent across the British Isles.

The early one there,

the more easterly feature, bringing a wet start across eastern parts

and then we're going to drag this weaker feature down

and across England and Wales later in the day.

Behind that, there's a pretty decent chance

of seeing some decent spells of sunshine

and I think they'll be at their best

perhaps across Angus and Aberdeenshire.

Out towards the north and west, plenty of showers,

similar sort of mixture across Northern Ireland.

Here, across England, having had some sunny spells,

they may well fade away

as that more westerly feature just

drags its way down across northern parts of England,

through Wales, and some showers, if not longer spells of rain there.

But as we move on into Wednesday, quite an interesting day here

because not only have we got a very vigorous area of low pressure

close to the northern half of Scotland -

70mph gusts perhaps in there for a time -

but this weather feature here,

a band of cloud and rain

and some pretty strong winds, will work its way slowly

but surely down across all parts, there is no escape from that.

The last of the mild air in association with that,

following on behind despite the presence of the sunshine,

it's a mixture of sunny spells and showers.

Notice as we go from Wednesday into Thursday,

we still have quite tightly packed isobars so the wind again a feature.

Much of it, though, across the British Isles

still coming from the south-west.

That's really quite important.

That's going to keep a relatively mild feel to proceedings.

But the temperatures will have slipped back by a degree or two

at the very least

and then just notice across this north-western quarter,

no longer the south-westerlies,

the wind wanting to get round towards a north-westerly.

At this time of year, that's a really quite cool direction

exacerbated by the fact those isobars are quite tightly

packed again. So there will be an edge to the breeze, shall we say?

If not a full-on wind,

nay a gale here across this north-eastern quarter of Scotland.

Look at the temperature profile -

5 to 9, where on Tuesday,

we were talking about sort of 10 to 13 or 14 degrees perhaps.

That short, sharp shock is just that

because as we start the weekend,

the isobars are lying somewhere out to the west and the south-west,

but again it brings the possibility of frontal systems,

increasing the cloud.

Bits and pieces of rain moving in across Western Scotland,

the north-west of England, maybe the top end of Wales

and back into Northern Ireland too.

Saturday definitely drier down towards the south-eastern

quarter, but at least that whole frontal system has imported

milder airs for the greater part of the British Isles.

Into the following week,

it could well be that we see a high pressure moving in under this

great big eddy in the jet stream

and that could really settle things down across the southern

half of the British Isles, but less so as it runs

out of influence across the very far north of Scotland.

So the driest of the weather in the south.

There will be a risk of some fog and frost.

Wet and windy in the north, we suspect,

but I think it could well be that it will be a little bit milder there.

Lots going on. Take care. Bye-bye.
