Hello. After Christmas Day, it looks like the weather pattern is going | 0:00:02 | 0:00:04 | |
to be much more changeable, very unsettled conditions to come. | 0:00:04 | 0:00:08 | |
In the run-up to Christmas Day, things are very quiet. | 0:00:08 | 0:00:11 | |
We are keeping the cold air at bay for the time being. | 0:00:11 | 0:00:13 | |
Mild conditions across the UK | 0:00:13 | 0:00:15 | |
because the jet stream is in this position, | 0:00:15 | 0:00:17 | |
so it is to the north of us, | 0:00:17 | 0:00:19 | |
so we are on the warmer, milder side of that. | 0:00:19 | 0:00:22 | |
But that mild air comes with a lot of cloud. | 0:00:22 | 0:00:25 | |
Essentially, we've got this flow of westerly winds with | 0:00:25 | 0:00:28 | |
high pressure to the south, low pressure to the north of us | 0:00:28 | 0:00:31 | |
and on those weather fronts, as they get closer to the UK, | 0:00:31 | 0:00:34 | |
we'll see some spells of rain. | 0:00:34 | 0:00:36 | |
After a dull and damp start on Friday, | 0:00:36 | 0:00:38 | |
many areas will become drier. | 0:00:38 | 0:00:40 | |
We may get some drizzle across the Highlands of Scotland | 0:00:40 | 0:00:43 | |
as cloud comes in here. | 0:00:43 | 0:00:44 | |
Best chance of seeing some sunshine | 0:00:44 | 0:00:46 | |
probably in the north-east of Scotland. | 0:00:46 | 0:00:48 | |
But under the cloud, and there will be a lot of it | 0:00:48 | 0:00:50 | |
and there may be some hill fog too, | 0:00:50 | 0:00:52 | |
the temperatures could be 10 to 12 degrees. | 0:00:52 | 0:00:54 | |
And not really falling very much overnight. | 0:00:54 | 0:00:57 | |
We've got the strong winds coming in across the more northern | 0:00:57 | 0:00:59 | |
parts of the UK. | 0:00:59 | 0:01:00 | |
That rain beginning to develop a little more widely | 0:01:00 | 0:01:03 | |
across the Highlands and up towards the Northern Isles too. | 0:01:03 | 0:01:05 | |
A lot more cloud across eastern areas of Scotland, | 0:01:05 | 0:01:07 | |
so temperatures here won't be quite as low. | 0:01:07 | 0:01:10 | |
Elsewhere with cloudy skies, | 0:01:10 | 0:01:12 | |
a mild night - 8 or 9 degrees. | 0:01:12 | 0:01:14 | |
We still have this same weather pattern then, | 0:01:14 | 0:01:16 | |
high pressure to the south of us dominating. | 0:01:16 | 0:01:18 | |
Lower pressure to the north. | 0:01:18 | 0:01:19 | |
Run of Atlantic winds | 0:01:19 | 0:01:21 | |
and on that weather system we are going to find some more rain. | 0:01:21 | 0:01:24 | |
So this is Saturday, the start of the weekend. | 0:01:24 | 0:01:26 | |
We've got those winds continuing to | 0:01:26 | 0:01:28 | |
strengthen across the northern half of the UK. | 0:01:28 | 0:01:30 | |
More rain coming into the north-west of Scotland, | 0:01:30 | 0:01:32 | |
maybe where we've got some shelter from the hills, | 0:01:32 | 0:01:34 | |
we may see a little sunshine coming through. | 0:01:34 | 0:01:36 | |
But on the whole, it remains cloudy, it remains dry, quite misty | 0:01:36 | 0:01:40 | |
and murky over some of the western hills. | 0:01:40 | 0:01:42 | |
Very mild. Temperatures again 10 to 12 degrees. | 0:01:42 | 0:01:45 | |
Christmas Eve now, and things starting to turn | 0:01:45 | 0:01:47 | |
wetter across Scotland, particularly Western Scotland. | 0:01:47 | 0:01:50 | |
The rain adding up more and more | 0:01:50 | 0:01:52 | |
and some rain coming into Northern Ireland. | 0:01:52 | 0:01:54 | |
Some drizzle over some western hills but otherwise a mild and cloudy day. | 0:01:54 | 0:01:59 | |
We've got low-pressure developing along that weather front | 0:01:59 | 0:02:02 | |
which is going to start to change things | 0:02:02 | 0:02:04 | |
Christmas Day and beyond. | 0:02:04 | 0:02:06 | |
So it is buckling our band of wet weather, | 0:02:06 | 0:02:08 | |
pushing it back northwards again across Scotland | 0:02:08 | 0:02:10 | |
where there's still some colder air over the Highlands | 0:02:10 | 0:02:13 | |
and Grampians where there could be some snow. | 0:02:13 | 0:02:15 | |
Otherwise, heavy rain in Scotland coming into Northern Ireland. | 0:02:15 | 0:02:17 | |
England and Wales, windy but very mild and cloudy. | 0:02:17 | 0:02:21 | |
Temperatures 10 or 11 degrees. | 0:02:21 | 0:02:23 | |
That's the last of the really mild air, though. | 0:02:23 | 0:02:25 | |
I think as we head into Boxing Day, | 0:02:25 | 0:02:26 | |
temperatures will drop a little bit, | 0:02:26 | 0:02:28 | |
particularly across Scotland and Northern Ireland as we get | 0:02:28 | 0:02:31 | |
some colder but drier air moving down into England and Wales. | 0:02:31 | 0:02:35 | |
But the really cold air is across the other | 0:02:35 | 0:02:37 | |
side of the Atlantic into North America. | 0:02:37 | 0:02:40 | |
This colder air is going to drive its way across the Atlantic | 0:02:40 | 0:02:43 | |
towards the UK from time to time beyond Christmas. | 0:02:43 | 0:02:47 | |
So this is after Christmas Day and we're getting a strengthening | 0:02:47 | 0:02:50 | |
jet propagating right the way across the Atlantic. | 0:02:50 | 0:02:53 | |
It squishes away the high pressure and instead of high pressure, | 0:02:53 | 0:02:57 | |
we're probably going to pick up areas of low pressure and drive them | 0:02:57 | 0:03:01 | |
towards the UK just like this. | 0:03:01 | 0:03:02 | |
Lots of isobars on the chart. It will be wet, it will be windy. | 0:03:02 | 0:03:06 | |
Still this colder air tucking in across northern areas | 0:03:06 | 0:03:08 | |
of the UK from time to time, | 0:03:08 | 0:03:10 | |
so there is the threat of some snow | 0:03:10 | 0:03:13 | |
across the North where we get these colder spells. | 0:03:13 | 0:03:16 | |
But on the whole, very unsettled weather, rain could be quite heavy | 0:03:16 | 0:03:19 | |
at times and it will be accompanied by some strong to gale-force winds. | 0:03:19 | 0:03:23 | |
So very different weather from what we're seeing at the moment. | 0:03:23 | 0:03:26 | |
That's it, goodbye. | 0:03:26 | 0:03:28 |
