Hello. If you saw the news earlier this week you will have | 0:00:02 | 0:00:04 | |
seen all of that snow across the northeast of the United States | 0:00:04 | 0:00:07 | |
which then pushed its way into Eastern Canada. | 0:00:07 | 0:00:09 | |
That was Storm Stella, | 0:00:09 | 0:00:11 | |
now moving away from North America. | 0:00:11 | 0:00:13 | |
It's heading across the Atlantic, | 0:00:13 | 0:00:15 | |
heading our way but it's not going to be | 0:00:15 | 0:00:16 | |
anything like it was in North America, | 0:00:16 | 0:00:18 | |
it's mostly going to be rain, | 0:00:18 | 0:00:19 | |
and it's being pushed by this fairly flat | 0:00:19 | 0:00:22 | |
jet stream. It's a zonal flow, that's | 0:00:22 | 0:00:24 | |
what we call it when it's a fairly flat jet. | 0:00:24 | 0:00:26 | |
As it moves into the UK it's going to be | 0:00:26 | 0:00:28 | |
a spell of wind and rain. | 0:00:28 | 0:00:30 | |
There will be some snow | 0:00:30 | 0:00:31 | |
but it's really only over the higher ground | 0:00:31 | 0:00:33 | |
in Scotland. A bit of rain in the northwest. | 0:00:33 | 0:00:35 | |
The further south you are, after a | 0:00:35 | 0:00:37 | |
bright start it'll tend to cloud over | 0:00:37 | 0:00:38 | |
into the afternoon but it should stay dry. | 0:00:38 | 0:00:40 | |
12 or 13 in the London area, | 0:00:40 | 0:00:42 | |
7s, 8s and 9s across Scotland. | 0:00:42 | 0:00:44 | |
Through Friday evening there's | 0:00:44 | 0:00:46 | |
plenty more rain to be had in the | 0:00:46 | 0:00:47 | |
northwest of the UK. | 0:00:47 | 0:00:48 | |
Some gets across to the eastern side | 0:00:48 | 0:00:51 | |
but it shouldn't be too heavy | 0:00:51 | 0:00:52 | |
not too persistent, but some rain nonetheless. | 0:00:52 | 0:00:55 | |
As we head towards dawn on Saturday | 0:00:55 | 0:00:57 | |
it's 8 or 9 degrees quite widely, | 0:00:57 | 0:00:59 | |
but with the clearer skies across | 0:00:59 | 0:01:01 | |
the Northern Isles we could go down to | 0:01:01 | 0:01:03 | |
around about freezing. | 0:01:03 | 0:01:04 | |
Through Saturday we've still got this | 0:01:04 | 0:01:06 | |
flow coming out of the Atlantic and still | 0:01:06 | 0:01:08 | |
a fair number of isobars on the chart | 0:01:08 | 0:01:10 | |
so it's going to be a windy weekend for many, | 0:01:10 | 0:01:13 | |
and that'll be a key feature of things | 0:01:13 | 0:01:15 | |
across pretty much all parts. | 0:01:15 | 0:01:17 | |
There will be some rain to be had | 0:01:17 | 0:01:18 | |
but most of the rain on Saturday looks to be | 0:01:18 | 0:01:20 | |
in the north and west of the UK. | 0:01:20 | 0:01:22 | |
Some gets across the Pennines | 0:01:22 | 0:01:23 | |
but not a great deal. Some parts of the | 0:01:23 | 0:01:25 | |
southeast and northeast should stay dry. | 0:01:25 | 0:01:27 | |
9 or 10 degrees in Scotland. | 0:01:27 | 0:01:30 | |
Could go as high as 15, maybe 16 | 0:01:30 | 0:01:32 | |
in the southeast. | 0:01:32 | 0:01:33 | |
As we head through Saturday evening | 0:01:33 | 0:01:35 | |
and on to Sunday, still weather fronts | 0:01:35 | 0:01:37 | |
coming in from the Atlantic. | 0:01:37 | 0:01:38 | |
This broad warm sector Saturday night | 0:01:38 | 0:01:40 | |
into Sunday should keep temperatures up a bit | 0:01:40 | 0:01:42 | |
but it's still going to be very windy out there, | 0:01:42 | 0:01:44 | |
lots of isobars on the chart. | 0:01:44 | 0:01:46 | |
Again, on Sunday, a windy day and | 0:01:46 | 0:01:48 | |
there'll be some rain to be had | 0:01:48 | 0:01:49 | |
but again it's mainly | 0:01:49 | 0:01:51 | |
in the western side of the UK will see | 0:01:51 | 0:01:53 | |
the heaviest of the rainfall. | 0:01:53 | 0:01:54 | |
Head further east | 0:01:54 | 0:01:56 | |
and the rain is light and patchy. | 0:01:56 | 0:01:57 | |
Some places may well stay dry. | 0:01:57 | 0:01:59 | |
There should be a few breaks in that cloud, | 0:01:59 | 0:02:01 | |
particularly in the east of the Pennines. | 0:02:01 | 0:02:03 | |
On to Monday and a weak weather front just | 0:02:03 | 0:02:05 | |
drapes its way across | 0:02:05 | 0:02:06 | |
southern-most counties of England, | 0:02:06 | 0:02:08 | |
so it will be a cloudy affair here with some | 0:02:08 | 0:02:10 | |
outbreaks of rain and a bit of a breeze as well. | 0:02:10 | 0:02:12 | |
Further north, a scattering of showers on and off | 0:02:12 | 0:02:15 | |
but some spells of sunshine as well | 0:02:15 | 0:02:17 | |
and maybe a bit more of persistent rain | 0:02:17 | 0:02:19 | |
creeping its way into the far northwest | 0:02:19 | 0:02:21 | |
later in the day. As we head into Tuesday, | 0:02:21 | 0:02:24 | |
another weak weather front drifting its way | 0:02:24 | 0:02:26 | |
in from the Atlantic. | 0:02:26 | 0:02:27 | |
A fair number of isobars on the chart and that'll keep | 0:02:27 | 0:02:29 | |
things quite breezy. | 0:02:29 | 0:02:30 | |
That weather front will bring some rain | 0:02:30 | 0:02:32 | |
with it but it's all drifting its way | 0:02:32 | 0:02:34 | |
ever eastwards, followed by sunny spells | 0:02:34 | 0:02:36 | |
and a scattering of showers, those temperatures | 0:02:36 | 0:02:38 | |
coming down, only single figures for many. | 0:02:38 | 0:02:40 | |
We looked at the jet stream earlier on, it was | 0:02:40 | 0:02:44 | |
quite flat coming out across the Atlantic | 0:02:44 | 0:02:46 | |
but as we looked towards the latter parts | 0:02:46 | 0:02:48 | |
of next week it looks like it'll be digging | 0:02:48 | 0:02:50 | |
its way south then heading back north. | 0:02:50 | 0:02:52 | |
This is what we call a meridional pattern. | 0:02:52 | 0:02:54 | |
High pressure may develop | 0:02:54 | 0:02:56 | |
across the UK | 0:02:56 | 0:02:57 | |
which will help settle things down. | 0:02:57 | 0:02:59 | |
The jet stream is driven by temperature | 0:02:59 | 0:03:01 | |
contrasts between different air masses, | 0:03:01 | 0:03:03 | |
the colder Polar air to the north and | 0:03:03 | 0:03:06 | |
the much warmer tropical air to the south. | 0:03:06 | 0:03:08 | |
Just a hint that the southeast might be | 0:03:08 | 0:03:10 | |
on the warm side of the jet | 0:03:10 | 0:03:11 | |
whereas the bulk of the UK later next week | 0:03:11 | 0:03:13 | |
looks like it will be on the cold side. | 0:03:13 | 0:03:15 | |
But at least it looks that bit drier, with high pressure in charge, | 0:03:15 | 0:03:18 | |
and there should be some sunshine as well. | 0:03:18 | 0:03:20 | |
But with the sunshine by daytime it means we are looking at some | 0:03:20 | 0:03:22 | |
rather chilly nights by the end of next week. | 0:03:22 | 0:03:25 | |
Gardeners take note cos the frost could well be quite widespread. | 0:03:25 | 0:03:28 |
