15/03/2018 Weather for the Week Ahead

Hello. Thanks very much for joining me.

I'm sure you know how this show works by now -

we give you some detail about the next five days

and then we'll take a look at some of the themes that we expect to see

in the forthcoming week. In the short term,

our weather very much dominated by this area of low pressure,

the attendant front gave a wet spell of weather for Northern Ireland

and the southwest of England.

As we get towards lunchtime on Thursday,

that same weather front will have

moved up into the Borders

of Scotland, eastern England,

brighter skies following behind,

but quite a raft of showers,

and some of those quite heavy,

maybe a rumble of thunder,

but temperatures not that disappointing

if you're away from the weather front.

If you get sunshine in the southwest, 11, 12 or 13,

underneath the front, 6, 7 or 8 degrees.

Not a great deal changes on Friday,

except we're pushing that front

further north,

and as it runs into colder air

across the hills,

particularly of northern Britain,

I think we'll see a conversion

of some of that rain into snowfall,

but it will be a high-ground feature.

Further south, there's sunshine to be had,

still some spring warmth at this stage,

but some hefty showers.

Catch one of those, you'll know all about it.

Moving towards the weekend,

and there's a none-too-subtle change

in our weather, because the low pressure will have drifted away

towards the Atlantic, and it'll be the big Scandinavian high

that will be providing a very noticeable

and noticeably cold wind

across all parts of the British Isles,

and there is a chance in that flow

at this stage

of seeing some wintry showers,

especially but not exclusively

across eastern parts.

Look at the difference in the temperatures.

You're well down into single figures

and we keep the same sort of feel to the day

as we move from Saturday on into Sunday,

thanks to that high pressure being very much the dominant feature

at this stage, and there'll be some strength in that flow

around the high pressure all the way from Siberia and Scandinavia

right across the whole of the British Isles,

but it's exposed eastern and southern areas that will see

the bulk of the snowfall,

and there is a chance there could be significant snowfall in the south.

We've shown it here more towards the Channel. It could come

a little further north. Remember, we are some way into the future here

on Sunday. Look at those temperatures.

1 to 6 degrees

just about covering it.

So, this is how we start the new week,

the high pressure just beginning to

drift from Scandinavia

out towards the northern parts

of the British Isles,

and therefore, we've got our own

circulation, and we're not relying

on a feed from a cold Siberia

or indeed Scandinavia,

so whilst there's going to be

some delay in the rebound in the temperatures,

first signs of recovery

already on Monday.

OK, it's relative,

it's 4, 5, 6 degrees or so,

and that's because, slowly but surely,

we're going to be entraining

somewhat milder airs from the Atlantic

and they will come to dominate the British Isles,

elbowing aside the cold snap

that many of us will have endured

during the course of the weekend.

As we get on into the forthcoming week,

we will very much be looking towards the Atlantic,

here is our old friend the jet stream,

underneath this jet stream, which is well up in the atmosphere,

we will see a succession of low pressures,

so, yes, it turns less cold, certainly,

but whilst that area of jet stream is firing the low pressures

at us, it will stay unsettled

and it will often be wet and windy. Bye-bye.
