12/07/2017 Weather for the Week Ahead

Hello there. It was a mud-free Glastonbury,

and so far so good in terms of the weather for Wimbledon 2017 -

until Tuesday, and the umbrellas were out for Murray Mount as rain

stopped play on the outer courts.

At least Johanna Konta gave us something to smile about,

but there was also plenty to smile about for gardeners

and growers, some heavy rain moving its way across England and Wales.

We could see as much as an inch of rain in many

places before this system clears through,

and that will be the first significant rainfall across

much of eastern and south-east England so far this month.

But it WILL slowly clear through

and leave a legacy of cloud first thing in the morning.

A bit more of a stiffer breeze along exposed east coasts,

but the sunshine will break through as the day progresses.

It'll be quite a pleasant day, and in sheltered western areas,

the temperatures are going to respond,

a degree or so up on what we've seen on Tuesday,

with highs of 19 to 23 degrees, just that little bit fresher

along the east coast, 15 to 18 with the breeze coming in off the sea.

Now, as we move into Thursday, we'll see a ridge of high pressure just

building and staying with us before this little weather front

introduces more showers,

and again we see this unsettled mobile westerly theme continuing.

But Thursday will be a relatively dry day,

with some sunny spells and just a few isolated showers cropping up.

More significant showers by the end of the day into the far north-west.

Here, highs of 16 or 17 degrees.

Elsewhere, we'll see temperatures responding at 20 to 23.

That weather front will enhance some showers as we move

through Thursday into Friday.

Nothing particularly significant with it.

The winds will swing round to a fresher north-westerly feel

and, generally speaking, we've got that mobile westerly flow, so

the potential for a few more showers along exposed west-facing coasts.

But, again, with a little more shelter we'll see

highs of around 16 to 22 degrees in the south-east.

Rain threatens from the west,

this mobile westerly theme set to continue,

and we'll see the isobars squeezing together, so there's some

wetter and windier weather to come for the start of the weekend.

But as that weather front drifts its way south and east,

it weakens off substantially.

There's a risk, though, of breezier conditions,

more showers to come, potentially, on Saturday.

But if the showers ease through and we keep some sunshine,

the wind's coming from a south-westerly direction,

so a degree or so warmer.

That weather front still a little bit of a nuisance into Sunday.

I just want to draw your attention to the high pressure

building down into the south-west.

So far this week, we've seen a pretty mobile westerly flow,

so we keep the showers going potentially out to the west,

but a good deal of dry, sunny weather, and with some sunshine

we'll start to see some warmth building in the south-east,

25 degrees.

The jet stream has been sat pretty much across the UK and has delivered

this westerly flow,

but we'll see more of an amplified jet stream into next week.

That's going to allow that high pressure to build

that I pointed out and drive in some warmer air across the country,

even starting to feel hot and humid again from the south.

There's only one slight potential problem -

and it is only a slight problem -

we could just see a low pressure developing into the south-east,

and that, as it bumps into the humidity, could trigger

off some sharp, thundery downpours in the longer six-to-ten-day period.

The best of the drier weather looks likely to be into the far north

and west. Still a lot to play for.

Don't make this the last forecast you're going to see.
