11/12/2017 Weather for the Week Ahead

Hello. Sunday was certainly a day to keep us meteorologists on our toes.

It was a day of some big extremes

and big travel problems as well.

Let's start with the snow.

We saw a foot of snow fall quite readily across the hills of Wales.

Some of you saw a little bit more than the 30 centimetres

recorded at Sennybridge.

Much, much milder to the south coast of England and Wales.

Around the Bristol and English channels, we saw severe gales

peaking over open waters of the English Channel at around 90mph.

Quieter further north, yes, but colder.

Parts of Scotland didn't get above -7 through the entire day.

And, of course after temperatures like that by day,

we start Monday on a very, very cold note.

One thing to keep our eye out for on Monday, amongst others,

is this area of low pressure.

It's going to be another day of weather extremes for some.

We've got severe gales across in France.

Some of those will get very close to the south-east through the day.

Outbreaks of rain - East Anglia and the south-east corner which

will turn to snow at times, particularly over the hills.

We'll see further snow flurries in parts of Scotland, Northern Ireland

and across the far western fringes of Wales and Cornwall.

But for most, it's a dry and raw day.

Lots of sunshine overhead,

but after that icy start,

barely above freezing and more ice as we go into Monday night.

The showers decaying back towards the coasts.

Again, a little bit wintry in places

but nowhere near as severe as we've seen through the weekend.

What will be severe is the frost to take us

through Monday night into Tuesday morning.

Where snow is lying,

-12 is possible just about anywhere in Scotland, England and Wales.

In particular, that's because we've got a ridge

of high pressure building in keeping winds light,

but it also takes us into the quietest weather day

of the week by and large.

There will be some fog around in the morning.

There will be used a few showers around some western

and eastern coasts, but for most, it's a dry day, a sunny day,

temperatures only just creeping above freezing.

Some will stay below freezing all day long,

especially where there is a good pack of snow lying on the ground.

But signs of changes towards the west later on.

Cloud will increase, patchy rain into Northern Ireland

and the far west of Scotland later.

All linked into this weather front which will introduce less cold

Atlantic air as we go through Tuesday night and into Wednesday.

So not as cold on Tuesday night

but outbreaks of rain pushing its way eastwards.

Some heavy bursts and we could see a little wave

develop on the front and that could intensify the rain.

Add that to snowmelt,

there could be a minor problem with some flooding and

we'll see more showers,

and longer spells of rain pushing from the west later.

The wind is going to turn to a north-westerly

direction that will bring slightly colder air once again.

Again, not on the levels we've seen through the weekend

but a chilly second-half to the week after a brief

lift in the temperatures on Wednesday.

A more straightforward picture of sunshine and showers for Thursday.

Showers most prevalent to the south-west of the country.

Snow mainly on the hills.

Most it will be rain, hail and sleet.

Rumbles of thunder with it.

Northern, eastern areas always a bit drier and brighter.

Had a bit of frost here to start the day and a bit of frost as well

to take us through Thursday night into Friday.

The low pressure pushing its way eastwards,

that opens the door back to northerly winds once again.

It's going to stay cold towards the end of the week.

Those showers that we've seen recently

across the far west of Wales will be back.

And the showers wintry in nature to the east of Scotland

and eastern parts of England. But many will be dry and sunny.

So we go into the weekend, cold air in place, look west -

another wodge of mild air trying to push in,

but cold air waiting in the wings once again.

Next week will be an oscillating week.

Certainly through the weekend, it will be cold,

a few wintry showers mainly around the coast.

Many will be dry and sunny but with frosty nights.

By the end of the weekend,

into the start of next week, it starts at milder once again but with

some wet and windy weather and then could cold air be back later?

We'll keep you updated.
