06/09/2017 Weather for the Week Ahead

Hello there. Weather headlines for the next couple of days are likely

to be dominated by Hurricane Irma,

but back closer to home things have been a little bit quieter

for the start of this week.

Yes, we saw some rain on Tuesday, as you can see

by this Weather Watcher's picture in Aberdeenshire.

But for the second consecutive day it was Dorset that had

the breaks in the cloud and some sunshine, quite pleasant here.

Things will change, a fresher feel as we start to see a few more

isobars on the chart and the wind direction

swinging round to a fresher westerly.

It looks as though Wednesday will be a pretty quiet day,

there will be some decent breaks in the cloud, some sunshine for many,

with that westerly wind just feeding a little more cloud in

from the coast there. And we could see a scattering of showers.

Top temperatures down on comparrison to the last couple of days,

14-20C the high.

Now as we move out of Wednesday we continue with this story,

and weather conditions will turn a little bit fresher

through the night, perhaps in more rural parts

we'll have temperatures down to single figures.

But at the same time, into the far north and west,

the cloud and the rain will gather,

an indication of what's to come as we move into Thursday.

In fact, there's an area of low pressure that's going to move in

and it will bring some rain,

some of it heavy, across Scotland and Northern Ireland.

For England and Wales, not too bad a start to Thursday.

Again, predominantly fine and dry.

A little more cloud around, perhaps sheltered southeastern areas

seeing the best of the sunshine, but by the end of the day

it will spill its way a little but south into northern England

and perhaps north Wales.

Here, temperatures more subduded, 13-15C,

but highest values again of 20 in the southeast corner.

Now as we move out of Thursday into Friday, that area of low pressure

will sink its way steadily south and east and

it'll be a little bit more significant for all of us on Friday.

There's going to be some rain for all of us at some point.

Starting off pretty wet, pretty miserable across

central and southern parts of England. Behind that front

we'll see squally showers developing,

heavy with some hail and thunder and

the winds driving those showers in along the northwest coast.

13-18C, so temperatures a little bit subdued,

really, for the first week of September.

As we move out of Friday,

that area of low pressure really just anchors itself

across the far north and that's always going to feed in

these showers across the north and west facing coast,

the wind direction coming from the north, never a warm source, really.

13-15C the high here, 19, possibly, in the southeast corner.

And it looks as though as we start off into Sunday,

things will quieten down, but not for long.

Another area of low pressure arrives in from the Atlantic,

and this will sweep its way pretty quickly south and east.

So an early, dry and perhaps bright start in the southeast,

the cloud will gather, the rain arrives, the wet and windy weather

pushes in through Scotland, Northern Ireland

and eventually across England and Wales,

that during the latter stages of Sunday.

And if this area of low pressure is sitting in this position on Monday

it could be potentially quite a stormy day.

Plenty of isobars packed around that area of low pressure,

quite unusual, really, for the first week of September.

However, I have a glimmer of good news for you,

things look likely, potentially, to calm down,

as we see an area of high pressure building

in the longer eight-ten day period,

and this high pressure, well, it's a blocking high.

It's going to prevent those mobile westerly fronts

moving in from the Atlantic.

So things will turn a little bit quieter with lighter winds,

but the wind direction always coming from the north so cooler by day

and particularly through the night with a chance of some light frost.
