Hello again. Yesterday I spoke about the battle taking place | 0:00:04 | 0:00:06 | |
between high pressure, low pressure, warm air and cold air. | 0:00:06 | 0:00:08 | |
That battle has not been resolved. | 0:00:08 | 0:00:10 | |
There is considerable uncertainty in the outlook. | 0:00:10 | 0:00:12 | |
We'll get there in the moment. This is Tuesday's weather though. | 0:00:12 | 0:00:15 | |
The rain is further north. | 0:00:15 | 0:00:17 | |
To the south we've got some sunshine and some showers. | 0:00:17 | 0:00:20 | |
If there is any sunshine in Scotland it's in the north-west Highlands. | 0:00:20 | 0:00:23 | |
The rest of Scotland looks cloudy as does Northern Ireland | 0:00:23 | 0:00:26 | |
and northern England. | 0:00:26 | 0:00:27 | |
There will be some outbreaks of rain and that rain could be quite | 0:00:27 | 0:00:30 | |
heavy in northern England and temperatures will be quite | 0:00:30 | 0:00:32 | |
a bit lower in north-west of England than they were on Monday. | 0:00:32 | 0:00:36 | |
It's to the south where we've got the warmth in response | 0:00:36 | 0:00:39 | |
from some sunshine, but that will bubble up the cloud, | 0:00:39 | 0:00:43 | |
Very hit and miss and a lot of places will be dry. | 0:00:43 | 0:00:45 | |
But there's a signal for some heavy | 0:00:45 | 0:00:47 | |
and potentially thundery ones in the south-west at this stage. | 0:00:47 | 0:00:50 | |
But once you lose the power of the sun so the showers fade away | 0:00:50 | 0:00:51 | |
and it dries off again. | 0:00:51 | 0:00:54 | |
But to the north we keep that thicker cloud, we keep the rain | 0:00:54 | 0:00:58 | |
and drizzle. | 0:00:58 | 0:01:00 | |
Temperatures about five, six degrees. | 0:01:00 | 0:01:01 | |
A little chillier maybe across the south where we break the cloud | 0:01:01 | 0:01:04 | |
and that could develop a little bit of mist and fog. | 0:01:04 | 0:01:07 | |
Here's the pressure pattern for Wednesday | 0:01:07 | 0:01:09 | |
though, still dominated by a big low pressure to the south of us | 0:01:09 | 0:01:11 | |
and that weather front is focusing rain and drizzle, | 0:01:11 | 0:01:17 | |
and perhaps northern England as well. | 0:01:17 | 0:01:19 | |
A bit lighter possibly by this stage. To the south some sunshine. | 0:01:19 | 0:01:23 | |
Look at the showers developing. | 0:01:23 | 0:01:24 | |
The heavier ones may be across Wales and the south-west. | 0:01:24 | 0:01:27 | |
You could get 17 degrees in London. | 0:01:27 | 0:01:29 | |
Contrast that with seven in Aberdeen. | 0:01:29 | 0:01:33 | |
Now, subtle change as we head into Thursday. | 0:01:33 | 0:01:35 | |
Low pressure close to the south-west but high pressure is trying | 0:01:35 | 0:01:38 | |
to topple into more northern areas of the UK. | 0:01:38 | 0:01:41 | |
What that will do with the rising pressure there is tend to | 0:01:41 | 0:01:45 | |
peter out a lot of the rain so it won't be as wet | 0:01:45 | 0:01:48 | |
across Scotland, Northern Ireland and Northern Ireland. | 0:01:48 | 0:01:50 | |
It's to the south where it will see most of the showers again, | 0:01:50 | 0:01:53 | |
some more persistent rain in the south-west perhaps, | 0:01:53 | 0:01:55 | |
because here we are closer to that area of low pressure. | 0:01:55 | 0:01:58 | |
Now into Friday. And Friday looks a bit of a mess to be honest with you. | 0:01:58 | 0:02:03 | |
I think many places will catch a shower or two. | 0:02:03 | 0:02:06 | |
Something more than that likely as well. | 0:02:06 | 0:02:08 | |
We've still got those temperature contrasts. | 0:02:08 | 0:02:10 | |
Chilly in the north, not as warm in the south | 0:02:10 | 0:02:13 | |
because we've got some wetter weather around. | 0:02:13 | 0:02:16 | |
And we've essentially got low pressure combining with | 0:02:16 | 0:02:18 | |
the weather fronts moving down from the north. | 0:02:18 | 0:02:20 | |
Once that pushes through we'll introduce some cleaner | 0:02:20 | 0:02:23 | |
air around that area of high pressure. | 0:02:23 | 0:02:25 | |
So it should be drier for Scotland and Northern Ireland, | 0:02:25 | 0:02:28 | |
some sunshine perhaps. | 0:02:28 | 0:02:29 | |
Still for England and Wales we're not clearing away that rain at all. | 0:02:29 | 0:02:33 | |
So things are moving much more slowly now. | 0:02:33 | 0:02:37 | |
Then we head into more uncertainty beyond that because high pressure is | 0:02:37 | 0:02:40 | |
trying to push in, and around the edge of that we've got this | 0:02:40 | 0:02:43 | |
push of colder air, drier air that's forcing that area | 0:02:43 | 0:02:47 | |
of low pressure away. | 0:02:47 | 0:02:48 | |
So over the course of next week high pressure could | 0:02:48 | 0:02:53 | |
build across the UK | 0:02:53 | 0:02:54 | |
and we may introduce a slightly milder south-easterly airflow. | 0:02:54 | 0:02:58 | |
But low pressure's not far away. | 0:02:58 | 0:03:00 | |
This is the most likely scenario. With higher pressure of course | 0:03:00 | 0:03:04 | |
it's going to be drier. | 0:03:04 | 0:03:05 | |
The nights may be chilly | 0:03:05 | 0:03:07 | |
but it should be dry with some sunshine during the day. | 0:03:07 | 0:03:10 | |
However a less likely scenario is that pressure will be lower and | 0:03:10 | 0:03:15 | |
that low pressure that wasn't far away could push back into the UK. | 0:03:15 | 0:03:19 | |
So that will bring a very different picture. | 0:03:19 | 0:03:21 | |
Instead up the sunshine you're more likely, especially | 0:03:21 | 0:03:24 | |
in the south-west, to catch some thicker cloud | 0:03:24 | 0:03:26 | |
and some rain at times. | 0:03:26 | 0:03:28 | |
A lot to play for in the next few days. | 0:03:28 | 0:03:30 |
