Despite the disappointing weather some of us have had this week,
at least it looks like a window of fine weather will coincide
with the weekend.
But thereafter, it's probably back business as usual.
We've had some rain crossing the country through Friday.
This is the band of cloud here.
You can see cloud strewn out right across the Atlantic,
so other areas of low pressure heading our way.
So it will be just a temporary dry spell.
As the weather systems and their drizzly rain
clear out of the way, it allows this ridge
of high pressure behind me to build in for the weekend.
But it will be a slow start to our Saturday morning.
It could be a bit grey, drizzly,
particularly in southern areas
with that weather front slowly exiting.
Then it's showers following on
the north-westerly breeze.
North-westerly isn't a particularly
warm direction for ourselves,
but at least it will blow in some sunshine,
just a scattering of showers
and not everywhere will see one.
The vast majority enjoying
a lot of dry weather,
not especially warm, 18 to 22 degrees Celsius.
But the cloud will clear quite quickly
through Saturday evening and overnight.
Quite chilly for the time of year.
We could see temperatures fall
to 2 or 3 degrees
across the glens of Scotland
which is close enough to a grass force.
As we had last weekend, actually.
But for the majority, just a chilly night,
It could be a bit foggy in a few places
first thing Sunday morning.
Again, there's still some strength
in the August sunshine
and there should be plenty of that
on offer on Sunday.
There are a few flies in the ointment.
One or two showers in the North
and the later in the day, rain comes
into Northern Ireland and western fringes of England and Wales.
That takes us into the week ahead.
So we've got this fine spell of weather, or mostly fine,
over the weekend, but it's back to business as usual next week.
In fact we could have potentially stormy weather late on.
The rain I talked about coming in late
to Northern Ireland on Sunday.
Moves in through Sunday night
into Monday and it's a slow mover,
quite heavy rain cos there's warm air in there,
which tends to generate a lot of heavy rain.
It looks at the moment as if perhaps
the far north will escape the worst
and perhaps the far south and east,
and not a bad day here on Monday.
The rain for many central and western areas,
but heavy rain and it continues on
through Monday night and into Tuesday.
Slowly creeping eastwards and at the same time
we may pick up some continental thunderstorms
coming into southern and eastern areas.
If those combine, we could have
some very wet weather potentially as we move into Tuesday.
But it should then move out of the way.
A ridge of high pressure starts
to topple in from the Atlantic,
pushing those weather systems out of the way,
so it freshens up and dries up
temporarily through Tuesday night.
So another chilly night, and into Wednesday,
but already behind me we've got trouble brewing.
This is the potential for some stormy weather
around the middle part of the week.
Now, the fly in the ointment
is that this has got some tropical air
mixed in with it, so it is going to prove
a problem for the computer models
to nail down the detail.
But at this stage it looks like it will whisk across the Atlantic,
turning to a fairly deep area of low pressure,
with gales, possibly severe gale force winds.
And a lot of rain because there's tropical air mixed in with it.
That's how the mid part of the week looks,
but you can see those weather systems trailing right the way
back across the Atlantic to the USA and Canada's shores, in fact.
And it's because we've got a strong jet stream
pushing across the Atlantic
and it's driving those low pressures
eastward towards our shores.
We're still to the north of the jet stream, still in the colder air.
Hence the fact there's nothing very warm
heading our way in the foreseeable future
and hence the fact that it'll stay generally unsettled.
But the next weekend we might be back into a brief
ridge of high pressure, possibly dry with some sunshine.
But the generally unsettled theme is set to continue.
