Hello. The emphasis for the next few days | 0:00:00 | 0:00:03 | |
and further ahead is going to be less on rain and more on cold. | 0:00:03 | 0:00:08 | |
Thankfully, on Thursday | 0:00:08 | 0:00:10 | |
it was a much drier day for those areas | 0:00:10 | 0:00:12 | |
badly affected by the recent heavy rain | 0:00:12 | 0:00:14 | |
in Cumbria and Lancashire. | 0:00:14 | 0:00:15 | |
Maybe one or two showers still around on Friday | 0:00:15 | 0:00:18 | |
but nothing worse than that. | 0:00:18 | 0:00:19 | |
We've got most of the showers, actually, | 0:00:19 | 0:00:21 | |
again wintry across Scotland and Northern Ireland. | 0:00:21 | 0:00:24 | |
The odd shower possibly across southern England after some | 0:00:24 | 0:00:27 | |
rain overnight. It could be a bit of a dull start | 0:00:27 | 0:00:29 | |
but most places will see the sunshine coming through, | 0:00:29 | 0:00:32 | |
a lot of dry weather around away from the north-west | 0:00:32 | 0:00:34 | |
but temperatures will be lower. | 0:00:34 | 0:00:36 | |
Four degrees Glasgow and Belfast, | 0:00:36 | 0:00:38 | |
Nine Celsius in London. | 0:00:38 | 0:00:40 | |
Temperatures are taking a downward trend. | 0:00:40 | 0:00:42 | |
Not windy on Friday | 0:00:42 | 0:00:44 | |
but the winds will start to pick up a little bit as we head overnight | 0:00:44 | 0:00:47 | |
into Saturday morning | 0:00:47 | 0:00:48 | |
driving those showers a bit further south. | 0:00:48 | 0:00:50 | |
Again, some sleet and snow in those, but it's colder air, | 0:00:50 | 0:00:53 | |
so we're looking at a frost perhaps more widely. | 0:00:53 | 0:00:55 | |
Almost anywhere, particularly in the countryside, | 0:00:55 | 0:00:58 | |
could wake up to a frost early on Saturday morning. | 0:00:58 | 0:01:01 | |
So a cold start, | 0:01:01 | 0:01:02 | |
north-westerly winds driving in some wintry showers | 0:01:02 | 0:01:04 | |
mainly across Scotland and Northern Ireland, across the north-west | 0:01:04 | 0:01:08 | |
of England feeding into Wales, one or two in the south-west. | 0:01:08 | 0:01:10 | |
But further east across the UK, it may well be a dry day, | 0:01:10 | 0:01:14 | |
quite a lot of sunshine around too, so that will help the feel | 0:01:14 | 0:01:17 | |
of the day but there's no disguising the fact that it will be cold. | 0:01:17 | 0:01:21 | |
The winds, picking up over the weekend, | 0:01:21 | 0:01:23 | |
will change direction a bit. | 0:01:23 | 0:01:24 | |
We've got this ridge of high pressure coming in ahead of these | 0:01:24 | 0:01:28 | |
weather systems off the Atlantic that will eventually bring a change. | 0:01:28 | 0:01:31 | |
So still quite windy on Sunday but because we're getting this ridge | 0:01:31 | 0:01:35 | |
coming in, we're losing a lot of the showers, so more places will be dry. | 0:01:35 | 0:01:39 | |
The sunshine hangs on in the east, | 0:01:39 | 0:01:40 | |
but in the west ahead of that rain | 0:01:40 | 0:01:42 | |
and those weather systems, | 0:01:42 | 0:01:44 | |
we'll get increasing cloud adding to the cold feel. | 0:01:44 | 0:01:46 | |
Nothing on that weather front there, the warm front. | 0:01:46 | 0:01:49 | |
All the rain is on the secondary front, | 0:01:49 | 0:01:51 | |
the cold front around that area of low pressure. | 0:01:51 | 0:01:53 | |
We're going to find rain sweeping its way in overnight, | 0:01:53 | 0:01:57 | |
continuing to drive its way into | 0:01:57 | 0:01:58 | |
south-eastern areas on Monday then moving away. | 0:01:58 | 0:02:01 | |
The wind direction changes back to north-westerly | 0:02:01 | 0:02:04 | |
and we start to drag down some colder air. | 0:02:04 | 0:02:06 | |
But Monday should be probably the mildest day of the next few. | 0:02:06 | 0:02:10 | |
Then as that area of low pressure moves away, | 0:02:10 | 0:02:12 | |
so we start to push our air all the way from the north once again | 0:02:12 | 0:02:16 | |
as this rather flat and long area of high pressure | 0:02:16 | 0:02:19 | |
blocks everything off from the Atlantic. | 0:02:19 | 0:02:22 | |
So we're drawing down colder air back across the UK | 0:02:22 | 0:02:26 | |
with northerly winds set to return. | 0:02:26 | 0:02:28 | |
So that means cold, it means sunshine, it means some showers. | 0:02:28 | 0:02:31 | |
The wind direction will be crucial. | 0:02:31 | 0:02:33 | |
More showers, wintry across northern Scotland, Northern Ireland, | 0:02:33 | 0:02:36 | |
running across western parts of England and Wales | 0:02:36 | 0:02:38 | |
not far away from the east coast | 0:02:38 | 0:02:40 | |
but a change in the wind direction such as we may | 0:02:40 | 0:02:43 | |
see on Wednesday may mean some more showers across the eastern | 0:02:43 | 0:02:47 | |
side of the UK and fewer showers out towards the west. | 0:02:47 | 0:02:50 | |
So subtle changes in the wind direction | 0:02:50 | 0:02:53 | |
changing the distribution of the showers. | 0:02:53 | 0:02:55 | |
Looking further ahead, | 0:02:55 | 0:02:57 | |
we need to look at the jet stream to explain what's going on. | 0:02:57 | 0:02:59 | |
This is high up in the atmosphere, the upper level winds | 0:02:59 | 0:03:02 | |
and with this configuration, | 0:03:02 | 0:03:03 | |
this buckling of the jet stream, you get high pressure | 0:03:03 | 0:03:06 | |
sitting to the west of the UK, | 0:03:06 | 0:03:07 | |
low pressure driven into south-east Europe | 0:03:07 | 0:03:09 | |
where it could be quite wet, not just rain but also some snow. | 0:03:09 | 0:03:12 | |
Now, we're going to see some snow over the outlook period | 0:03:12 | 0:03:15 | |
because the winds are going to be northerly. | 0:03:15 | 0:03:17 | |
So it is staying cold. | 0:03:17 | 0:03:19 | |
As we were talking about this time yesterday, | 0:03:19 | 0:03:21 | |
sunshine and wintry showers around and with some clear | 0:03:21 | 0:03:24 | |
skies at night, we're going to find some more frosts as well. | 0:03:24 | 0:03:27 | |
That's it, goodbye. | 0:03:27 | 0:03:28 |
