10/12/2017 Weather for the Week Ahead

Hello. Cold Arctic air not just affecting the UK at the moment,

it's also been affecting much of the US and Canada.

We've seen snowfall as far south as New Orleans over the past few days.

The area of blue, that Arctic air, pushes all way down the Gulf Coast.

As you can see, towards us.

But with the jet stream starting to strengthen,

over 200mph through this weekend,

we start to throw weather fronts our way into the air that we have

and with that a big risk of disruptive snowfall for Sunday.

Met Office amber warning in place across North Wales,

much of the Midlands.

It's these areas where travel disruption is certainly likely,

anywhere between 5-20cm of snow possible.

The northern edge a little bit uncertain but we'll see

snow get very close by into the morning,

the southern edge is going to be a mixture of rain

turning to snow, back to rain through the day.

The southernmost counties of England, this is where

we'll see mainly rain, same to the south of Wales,

and a different issue here, it's going to be the strength

of the wind, gales if not sever gale force winds,

that could cause disruption of its own.

Notice the snow across this central swathe of England

and Wales starts to peter out a little bit, turning

lighter and patchier into the afternoon,

far north of England, Scotland, Northern Ireland and

then a few wintry showers in the far north of Scotland,

most will have a dry and sunny Sunday. Pretty cold one, though,

temperatures struggling to get above freezing. Same where

you've got the snow in the south. Strong winds, they could get figures

into double digits.

Ice is then going to be the big risk as we go into Sunday night

as the patchy sleet and snow gradually clears

southwards. Some further snow showers in parts

of Scotland and Northern Ireland and a widespread frost.

Temperatures in the city centres like this

minus double digits through some parts of northern

England, north Wales and also parts of Scotland as well.

So a very cold start to Monday but we're watching this

area of low pressure. For us, the good news is it's driven

by a 200mmph jet stream. It looks like it'll

strengthen and hit Spain, Portugal and France greatest.

We could get close enough to bring severe gales

to the south-east corner, rain which could turn to snow on

its western flank, only a small chance at the moment

but one to watch. Sleet and snow flurries could cause

problems in Pembrokeshire, Carmarthenshire

and also parts of Cornwall. Much of the country cold, sunny

but rather raw.

We go into Tuesday, well, after a night of clear skies

and lighter winds there will be a severe, widespread frost,

especially where snow is on the ground, but Tuesday

itself slowly warming up through the day, dry, reasonably

sunny day for many, but changes afoot.

Now, we go into the middle part of the week with the Atlantic

starting to take over from Arctic air. This weather front

brings the change. Some snow on the hills to begin with,

turning to rain as that weather front pushes its way

eastwards, lying across eastern England to start

Wednesday. That will clear, sunshine out across eastern areas

in the afternoon. Frequent, heavy, thundery showers in

the west. Some of these could be sleet, hail and snow.

Snow though mainly over the higher ground. The air's not

quite as cold as we started the week.

We continue with those winds coming off the Atlantic

but starting to go a bit more north-westerly by the

time we hit Thursday. There will be some very windy

conditions through Wednesday night into Thursday. Could be

severe gales, and it's a sunshine, shower day for Thursday,

again some of those heavy with hail and thunder, sleet

and snow primarily over the hills. The second half of the

week not as cold as this weekend.

And then we go into next weekend. Friday and next weekend

looks like the winds will go back to north-westerly once again,

even northerly.

So it's going to be cold to finish the week going into the weekend.

There will be wintry showers around, snow mainly over the hills,

not as bad as we'll see on Sunday, the nights will be frosty

but next week things will turn

a bit milder and we'll get that

oscillating pattern to take us

through next week, too. Bye for now.
