Hello. Some would say, when high pressure's in charge across the UK, | 0:00:03 | 0:00:06 | |
it's Easy Street for forecasters. | 0:00:06 | 0:00:08 | |
Not necessarily true. | 0:00:08 | 0:00:09 | |
Although high pressure means we don't have to worry about rain, | 0:00:09 | 0:00:13 | |
cloud is always problematic. | 0:00:13 | 0:00:15 | |
And it's particularly problematic at this time of year, | 0:00:15 | 0:00:18 | |
close to the Equinox, when the sun makes such a difference to the day. | 0:00:18 | 0:00:22 | |
That's what's been happening this week. | 0:00:22 | 0:00:23 | |
High pressure has been dominating. | 0:00:23 | 0:00:25 | |
We haven't had to worry about rain, | 0:00:25 | 0:00:27 | |
but day on day variations have been huge. | 0:00:27 | 0:00:29 | |
Look at Monday, a largely sunny day | 0:00:29 | 0:00:31 | |
on the satellite image. By Tuesday, | 0:00:31 | 0:00:33 | |
the cloud is spilling back in from the East. | 0:00:33 | 0:00:35 | |
By Wednesday, the cloud holes | 0:00:35 | 0:00:37 | |
were all over the place, and yet by Thursday | 0:00:37 | 0:00:39 | |
we were back to largely sunny conditions | 0:00:39 | 0:00:42 | |
though it was pretty grey on some eastern coasts | 0:00:42 | 0:00:44 | |
and then again on Friday, | 0:00:44 | 0:00:45 | |
the cloud was back in from the East, | 0:00:45 | 0:00:48 | |
leaving just western areas | 0:00:48 | 0:00:49 | |
to bask in the spring sunshine. | 0:00:49 | 0:00:51 | |
The cloud is going to continue | 0:00:51 | 0:00:53 | |
to win out through the weekend. | 0:00:53 | 0:00:54 | |
Yes, we'll continue to see some holes, | 0:00:54 | 0:00:56 | |
particularly across Scotland. | 0:00:56 | 0:00:58 | |
Sunshine in places here. | 0:00:58 | 0:01:00 | |
But for most, it's cloudy. | 0:01:00 | 0:01:01 | |
But it is still, under the influence | 0:01:01 | 0:01:03 | |
of that high pressure, largely dry. | 0:01:03 | 0:01:05 | |
A little drizzle's likely here and there. | 0:01:05 | 0:01:07 | |
But again, temperatures really do | 0:01:07 | 0:01:09 | |
depend on the sunshine. | 0:01:09 | 0:01:11 | |
Where we see it, double figures or beyond. | 0:01:11 | 0:01:13 | |
For most of us, with the cloud, | 0:01:13 | 0:01:14 | |
we're just at 7 or 8 degrees. | 0:01:14 | 0:01:16 | |
Here's the high, continuing to slip | 0:01:16 | 0:01:18 | |
further south as we go through the weekend. | 0:01:18 | 0:01:20 | |
We're starting to see weather fronts topple in | 0:01:20 | 0:01:23 | |
across the north getting closer, | 0:01:23 | 0:01:25 | |
a sign of change. | 0:01:25 | 0:01:26 | |
A few more showers in northern Scotland. | 0:01:26 | 0:01:28 | |
But for most, it's dry and cloudy. | 0:01:28 | 0:01:30 | |
We'll see more sunshine on Sunday | 0:01:30 | 0:01:32 | |
across north-east England, | 0:01:32 | 0:01:33 | |
eastern parts of Scotland. | 0:01:33 | 0:01:35 | |
Again, the sunshine will make a huge difference. | 0:01:35 | 0:01:38 | |
This is the Azores high, | 0:01:38 | 0:01:39 | |
it's slipping back to its default position | 0:01:39 | 0:01:42 | |
over the Azores going into | 0:01:42 | 0:01:44 | |
the early part of next week. | 0:01:44 | 0:01:45 | |
But it will be a slow process. | 0:01:45 | 0:01:47 | |
It's still controlling things on Monday, | 0:01:47 | 0:01:50 | |
but again, a few more showers | 0:01:50 | 0:01:51 | |
in western Scotland. | 0:01:51 | 0:01:53 | |
With the breeze coming in more from the west, | 0:01:53 | 0:01:55 | |
eastern areas should be more favoured for sunshine. | 0:01:55 | 0:01:58 | |
Tuesday again, a similar picture, | 0:01:58 | 0:02:00 | |
though the winds become more from the south-west. | 0:02:00 | 0:02:02 | |
But generally dry and cloudy | 0:02:02 | 0:02:04 | |
for the first part of next week sums it up. | 0:02:04 | 0:02:07 | |
By the time we get to Wednesday, | 0:02:07 | 0:02:09 | |
the weather pattern looks more traditional, | 0:02:09 | 0:02:11 | |
with these weather fronts | 0:02:11 | 0:02:12 | |
trying to come in from the Atlantic. | 0:02:12 | 0:02:14 | |
But there's big question marks | 0:02:14 | 0:02:16 | |
about when we start to see a proper change. | 0:02:16 | 0:02:18 | |
It's all tied in with the jetstream. | 0:02:18 | 0:02:21 | |
For much of the week, we've had this pattern, | 0:02:21 | 0:02:23 | |
this blocking pattern. | 0:02:23 | 0:02:24 | |
The jetstream going to the north of the UK, | 0:02:24 | 0:02:26 | |
high pressure sitting over us keeping things dry. | 0:02:26 | 0:02:29 | |
The jetstream through the weekend, | 0:02:29 | 0:02:31 | |
early part of next week, gets a bit of a kick | 0:02:31 | 0:02:33 | |
and we get this more amplified pattern, | 0:02:33 | 0:02:35 | |
where the jetstream goes further north | 0:02:35 | 0:02:37 | |
and come south a little further west. | 0:02:37 | 0:02:39 | |
Hence why the high is starting to retreat. | 0:02:39 | 0:02:41 | |
And things slowly changing a little through the early part of next week. | 0:02:41 | 0:02:45 | |
If you think of the jetstream, | 0:02:45 | 0:02:46 | |
that fast-moving ribbon high up, | 0:02:46 | 0:02:48 | |
as a river, meandering, | 0:02:48 | 0:02:49 | |
then the default position for that river, | 0:02:49 | 0:02:52 | |
it always wants to go back to a more direct route, | 0:02:52 | 0:02:56 | |
that's Mother Nature's way of keeping things simple. | 0:02:56 | 0:02:59 | |
We will eventually go back to this jetstream | 0:02:59 | 0:03:01 | |
coming more in from the Atlantic, | 0:03:01 | 0:03:03 | |
providing more unsettled conditions. | 0:03:03 | 0:03:05 | |
But with such a strong block, | 0:03:05 | 0:03:07 | |
a strong pattern, it's difficult to say | 0:03:07 | 0:03:10 | |
exactly when we'll get back to that more typical condition | 0:03:10 | 0:03:14 | |
and the more unsettled weather. | 0:03:14 | 0:03:16 | |
But it does look as if, through Easter weekend, | 0:03:16 | 0:03:18 | |
it's likely to stay on the cool side | 0:03:18 | 0:03:20 | |
and we'll start to see more of that change, turning more showery, | 0:03:20 | 0:03:24 | |
particularly in the North, | 0:03:24 | 0:03:25 | |
but still a fair bit of dry weather, | 0:03:25 | 0:03:27 | |
at least for the first part of the weekend across the South. | 0:03:27 | 0:03:29 | |
Goodbye. | 0:03:29 | 0:03:31 |
