03/09/2017 Weather for the Week Ahead

Hello there. It's certainly turning into a weekend of two halves,

so I hope you made the most of the fine weather

that we had on Saturday.

In early September the land is still warmer than the sea

which is why we saw the cloud bubbling up

over land and coastal areas were lovely and sunny

and there were just sufficient depth to the cloud

across Suffolk and Norfolk to give us one or two showers on Saturday.

Those are clearing away

and instead the major changes coming in from the Atlantic.

The cloud has been thickening up and these weather fronts

will push rain very slowly eastwards

into the UK for the second half of the weekend.

There'll still be some hazy sunshine for a while in eastern Scotland

and eastern England and it may well

be dry for most of the day because

this rain is quite slowly pushing its way eastwards.

Initially some heavy bursts of rain on the hills in the west.

The rain becomes more drizzly and lighter through the day

but a lot of low cloud and it will be quite poor for western areas.

Less so near the east coast

where we have the best of the weather.

Even here through the evening and overnight

we may see a little bit of rain cropping up

but the tendency is for the rain to just peter out overnight.

We're left with a lot of low cloud, hill fog,

and some warm air to start the new week.

That weather front, then, moving into the UK

peters out, weakens.

The next one has a bit more oomph to it

and that's pushing into the back of that first one

and it will bring a spell of heavier rain perhaps to Northern Ireland,

more particularly into Scotland.

Ahead of that, to the south across England and Wales,

still cloudy still a bit damp out there as well

but we've got some warm air actually.

A bit of tropical air in the mix for Monday

so despite all of that cloudy, damp weather

we still could find temperatures into 22

or 23 degrees territory.

On that weather front, though,

there is potential for a wave developing which

will stall the progress and could bring a spell of

heavy rain across the UK on Monday night.

The worst of that rain clearing out into the North Sea.

The hang back of rain and cloud into the south-east for a while.

Then things brighten up.

We get some sunshine and there will be

a few showers in the north-west.

So some muggy air for a while towards the south-east,

but fresher air is coming in

from the west behind that weather front,

which does finally clear away.

Then we get this sort of attempt at

a bump of high pressure overnight

so probably a touch cooler, I think,

by the time we get to Wednesday morning.

There'll be some sunshine around.

Still got a westerly breeze, mind you.

Strongest up towards the north-west

and this is where we are more likely to see some showers,

perhaps some longer spells of rain.

If we don't get the longer spells of rain on Wednesday

it looks like we'll get it in the north-west on Thursday

as these weather fronts approach due to that area of low pressure.

And that sets us up really towards the latter part of the week.

Jet stream roughly in this position

and not as far south as it was

over the summer but still close to the UK,

picking up areas of low pressure,

driving them across the northern half of the country.

Further south, the Azores High tries to come in

to southern areas from time to time

and we're left, by the time we get into next weekend,

with some very mixed weather

across the north-west of the UK.

Closer to low pressure,

could be quite wet and windy for a while.

Higher pressure more towards the south and south-east.

Here next weekend

potentially something a bit drier

and a little bit warmer as well.

But on the whole,

the outlook as we go further into September is very mixed.

We'll find that strong jet stream pushing in some spells of rain.

There'll be some drier and brighter interludes

in between but may not feel that warm actually,

particularly in the north,

where the winds will be stronger.
