01/12/2017 Weather for the Week Ahead

Hello. Thanks for joining me.

I'm sure you know how these forecasts work by now,

we try to give quite a bit of detail on the shorter term of weather

and then as we look a little bit longer term,

we just try and pick out some of those trends.

No doubt about it, in the short-term, it's that wintry feel

that's likely to win out and the morning will again have offered

the opportunity of a bright but crisp and frosty start

for many central and western areas.

But as I show you the bigger picture, you get that sense

that maybe there is something of a change just waiting

in those northern and western wings

by way of relatively mild air,

relatively, compared to

what we've seen of late,

that early taste of winter

for some of you.

Many of these showers in the east

still urged along by quite a keen wind

will be watery on Friday rather than wintry.

Signs of more cloud and a bit of rain

getting into the far north-west

of Scotland to finish the day.

The best of the brightness

perhaps again through Wales,

the Midlands, and down

into the south-west of England.

Maybe those temperatures just a degree or two

up on where we were

in the middle part of the week.

Come the weekend, well,

a lot more cloud just rotating

around that north-eastern flank

of the high pressure,

slumping its way into the British Isles,

so no scraping of cars, I think,

to start off the new day on Saturday

and here those averages maybe again,

certainly in the west,

a degree or two higher than we have been

and no longer the 3 or 4 degrees

out towards the east.

Yes, it's only 5 or 6,

this is no new heatwave,

but at least we're beginning

to see a trend building.

I think that trend will continue

as the overall pattern stays

pretty much the same -

high pressure out towards the west,

weak weather fronts drifting their way down,

so maybe the odd spot of rain.

I'm not promising everybody

a completely dry weekend

by any means at all but the trend

that I really want to hammer home

is that we're getting 7, 8, 9, 10,

possibly 11 degrees, as the cold air

that has dominated our weather of late

is shunted to the near continent,

leaving behind it the prospect of the circulation

being very much dominated

by the high pressure

and a feed in from a relatively mild Atlantic

and there is no difference to the pattern

as we get on into Monday

and I can take you even further ahead

than that on into Tuesday.

I think the only change that we're picking up

at the moment is that maybe the centre of gravity

for the high is no longer completely blocking out

towards the west but it's rather slid its way

a little bit further towards

the south to become very much

the dominant player here but

maybe, just maybe,

that change of position of the centre

of the high is just beginning to open

a window of opportunity for something to develop

and something to change across

the northern half

of the British Isles.

So, midweek until the latter part

of the week, I'm not so much

looking for wild changes in the south,

but with time, we may just push

low pressures sort of through

this corridor and occasionally

that may just open up the door

for something a little bit cooler,

with the threat of snow showers,

especially on the higher ground, of course,

to break out across the northern parts of the British Isles.

Now, with some deal of uncertainty,

next weekend it could well be that as we establish a low pressure out

towards the east and high pressure again resuming its position out

towards the west, we may start drawing in something

a little bit colder again.

So certainly milder in the south throughout, unsettled further north

because of the transition of those lows

and it could be as far ahead as next weekend,

we see the return of something a good deal colder. Bye-bye.
