Hello. If you remember nothing else from the next few minutes
please remember that the weekend
will be a real shot of winter,
but before that we are still looking towards the Atlantic,
a relatively mild source of weather, to see what is going to
go on for most of us during the course of Friday.
It is still very much about
a weather front which seems to
have stalled with intent
across the eastern side of Scotland,
central parts too and into the north-east of England
and it will be joined eventually from the south by another
weather front bringing the prospect of some pretty hefty showers.
But at least behind that, there is some sunshine to be had
for the greater parts of England and Wales
and a bit of warmth as well.
From Friday into Saturday, it is
quite significant that the low-pressure drifts away
and we begin to look
to the main event of the weekend,
that high pressure over Scandinavia,
which, eventually, will start to
throw really cold air at us,
across all parts of the British Isles.
Riding on that stream of cold air, and there'll be
plenty of wind through the weekend.
There will be snow showers,
not just across eastern parts, I think some of them, given
the strength the wind, will make it
right across towards the Welsh mountains.
So if you are a thinking
about moving about over the weekend,
think about snow and ice.
There will be some disruption, I am sure, over the next few days.
So BBC local radio will keep you right up-to-date on that.
Now, Sunday, don't take this too literally,
but forget about showers for
southern parts of the British Isles,
because I think there'll be a more
organised area of cloud
and snow working its way
across the southern half
of the British Isles.
Don't take it too literally because we're not sure
whether it will be a bit higher,
it could be a bit lower.
We're not exactly sure, but wherever you are spending the weekend,
it will be bitterly cold.
Add in the strength of the wind,
it could feel like -5, -6, -7.
Eventually, that more organised belt of weather
gradually pulls away into the south-western approaches
and the high pressure begins to drift away from Scandinavia
and becomes very much ours.
That is quite important
because it cuts off the flow
of really cold air from Scandinavia
and Siberia and we begin to see something of a sea track
and that, at this time of year,
believe it or not is relatively mild.
Certainly compared to what is going on across Scandinavia and Siberia.
So it looks as though through Monday,
we will see some onshore winds
dragging wintry showers
across the high ground,
North York Moors, for example,
but the temperatures
just beginning to recover a touch
from that bitterly cold weekend.
We keep that process going through Tuesday.
The isobars just beginning to open up, so not so much
in the way of wind for the greater part of the British Isles.
You may not escape that down across East Anglia and the south-east.
Still a keen northerly wind.
Never a warm direction.
But at least things are beginning to settle down
and notice the temperatures -
7, 8, 9. Back into double figures
for the favoured few, perhaps,
in the Greater London area.
And on into the outlook period,
at last we begin to see the process of the Atlantic
really winning out and as a consequence of that,
on occasion there will be shots of relatively mild air.
So the weekend -
really a short, sharp shock.
Because even as far north
as we get on towards Wednesday and Thursday,
we'll be pushing towards double figures
and we will certainly have achieved that
elsewhere across the British Isles.
Things, eventually, post the weekend, will turn less cold,
but because we're seeing an influence from the Atlantic,
they will be unsettled and, at times, some of those low
pressures will bring some very wet and some very windy weather.
