00:00Good morning. A fine and dry start for many of us this morning, but it is already turning

00:06cloudy from the west and turning increasingly unsettled. The reason for that is our old

00:11friend the jet stream. This really powers up the weather from the North Atlantic. Normally,

00:15this time of year it's displaced well to the north, but it's running right the way across

00:19the UK at the moment and it's set to bring further outbreaks of heavy rain and wind at

00:24times for the rest of the week. And we are already seeing one of those bands of cloud

00:29and rain moving in across parts of Northern Ireland and Western Scotland. And that rain

00:34will become increasingly heavy and persistent during the course of the afternoon. And these

00:39southwesterly winds will also strengthen, particularly across the northern coast of

00:43Northern Ireland and Western Scotland, where I'd like to see coastal gales develop for

00:48a time. Further to the south and east, winds are a lot lighter and a few breaks in that

00:53cloud will allow those temperatures to actually rise into the low 20s. So looking at highs

00:59around 22 or 23. But for areas to the north under the cloud and rain, temperatures disappointing

01:07on the cool side of average for the time of year. So that band of cloud and rain across

01:12northwest areas will continue to push eastwards during the course of this evening and overnight.

01:18And that rain becoming heavy and persistent. And there'll likely be some local impacts,

01:23so difficult travelling conditions, some localised flooding. And we do have ourselves a yellow

01:28weather warning and that runs right the way through until Thursday. But overnight temperatures

01:34were generally well above where they should be for the time. It's going to feel quite

01:38humid within this weather system. We have the air of ex-hurricane Ernesto, so quite

01:44humid. Now, that band of cloud and rain continues to work eastwards during the course of Thursday.

01:52But as it pushes into the south and east, it's weakening all the time. Further to the

01:56west, it is brightening up. So a day of sunny spells and showers and those winds will also

02:01ease back for a time. And temperatures during the course of Thursday afternoon, very similar

02:07to the values we're going to see this afternoon, with highs of 22 or 23 across the south and

02:12east. But further to the north, we are still on the cool side of average. And that unsettled

02:18theme will continue as we move our way through to the rest of the week. Another spell of

02:24wet and windy weather on Friday, but maybe something a little bit more positive by the

02:28time we actually get to the bank holiday weekend. Thank you for watching. Cheers for now.
