00:00Hello, and welcome to the Met Office 10-day trend. Many places over the next few days
00:05will enjoy a lull in the unsettled weather, but it's not going to last. During the weekend,
00:10it turns very windy. Storm Kira likely to bring disruptive or damaging winds. And then
00:16through next week, the weather remains highly volatile. Colder conditions at the start of
00:21next week will bring blustery showers and snow over the hills of the UK. And then by
00:26the end of the week, the potential for at least one more very windy spell. Couldn't
00:31be further from what we're seeing over the next couple of days. High pressure in charge,
00:36calm winds and relatively dry conditions across the country. Frosty, foggy mornings, Thursday
00:42morning and Friday morning. Meanwhile, on the other side of the pond, things are starting
00:47to develop as bitterly cold Arctic air over Canada meets much more humid air further south.
00:54In fact, at around 5,000 feet, there's a temperature contrast of 30 degrees over the
00:59space of, well, what is effectively the length of the British Isles. And that is helping
01:05to fuel a very powerful jet stream, this fast flowing ribbon of air at around 30,000 feet.
01:11You can see the core of the strongest winds indicated by the dark colours there emanating
01:15out of Canada. And in this area, well, there's the chance that winds will exceed 260 miles
01:22per hour. That jet core helps to pick up and spin up deep areas of low pressure. You
01:29can see numerous lows there, but our focus for the weekend is Storm Kira on Friday, still
01:34coming out of Canada. But watch how quickly over the space of just 24 hours or so, Kira
01:38deepens and rapidly starts to approach the UK. By Saturday night and Sunday, Kira is
01:47crossing northern parts of Britain, tight isobars across the UK. And so the uncertainty
01:52in the week during the weekend isn't whether or not it will be windy. It will be windy
01:57and wet and unsettled. It's the exact focus where we're going to see the strongest winds.
02:04And that all depends on the precise interaction of Kira with the jet stream. We'll have more
02:09details over the next couple of days, of course. But for now, much of the UK is under a yellow
02:15warning. In fact, all of the UK is under a yellow warning. It all starts to change on
02:19Friday. High pressure drifts away. This cold front, not particularly unsettled feature.
02:25It brings a spell of rain, but it opens the door to westerlies. And from that point onwards,
02:31the weather is very unsettled. Saturday starts off relatively dry and calm, but quite quickly
02:36it turns wet and windy to the west. Rain of some importance as well through the weekend.
02:42It turns wet across western parts of Britain through Saturday. Some particularly wet weather,
02:4850 millimetres plus over western hills. Several bouts of rain moving through Saturday night
02:54as well as Sunday, brought in by these strong winds and followed by showers later Sunday.
03:00So some wet weather around Saturday night and Sunday. But the main focus are the winds.
03:06Like I say, the UK covered by a yellow wind warning. And it looks likely that northern
03:10and western parts of Britain will see gales developing on Saturday night and into Sunday.
03:15But during Sunday itself, well, there's the risk of gales widely across the UK, not just
03:20around coasts, but inland as well. The exact details in terms of where is likely to see
03:26the strongest winds and when. We'll provide further details, of course, over the next
03:31couple of days. On Sunday, it looks possible that there'll be a swathe of especially strong
03:36winds across Northern Ireland into parts of Scotland. But for now, suffice to say damaging
03:42gusts could occur anywhere. And there's risk in some places of gusts in excess of 80 miles
03:47per hour. So a lot to be wary of for the weekend. As storm Cura arrives, there's the risk of
03:54damaging winds. There's the risk of coastal impacts with large waves and overtopping on
03:59the coasts. And there's also the risk of power disruption and transport disruption where
04:04we see the strongest of the winds. Now, following storm Cura, the jet stream is sitting to the
04:11south of the UK by this stage and the core of the jet stream there, very close to the
04:15UK. And we're likely to see cold air dragged across the UK as Cura moves away. It's going
04:23to feel cold in the strong winds. In fact, on Monday, it will still be really quite windy
04:28with particularly strong gusts around these showers. A case of bright spells and showers
04:34really through Monday and Tuesday. And because of the cold air, these showers will be wintry
04:40in nature. Now, it's likely that northern parts of Britain are going to see a mix of
04:45sleet, snow and hail showers, even at lower levels. But there's no really only piling
04:50up over hills above 200 or 300 metres. Further south, rain and hail showers more likely at
04:56lower levels with snow over the hills, say Brecon Beacons, Dartmoor and Exmoor. And the
05:02jet stream is still a key factor in our weather from the middle of next week and beyond. You
05:07can see the power of that jet stream on Tuesday and that's going to help to deepen further
05:12areas of low pressure with one area of low pressure in particular. We're keeping our
05:17eye on for Wednesday to Thursday. Could be another spell of disruptive winds. So we'll
05:24be firming up on the details of that over the next week or so as well. And well, beyond
05:30that, the weather looks like remaining very unsettled. So days 7 to 10, Wednesday, Thursday,
05:36another very windy spell, risk of gales. And because next week sees the arrival of high
05:42tides, there's the risk of some particularly rough seas and coastal impacts. Beyond that,
05:48into Friday, Saturday, it stays unsettled with the potential for further areas of low
05:53pressure arriving across the UK from that powerful jet stream. So a lot to stay tuned
05:59to over the next few days. The best way to stay up to date with all the very latest is
06:03to follow us on social media. Bye bye.
