00:00Hi there. Some low cloud persisting overnight, but where we do see clear spells, there will

00:07also be dense fog patches, so a gloomy start in places by Tuesday morning. Most likely

00:12areas for clear spells, southern parts of England through the Midlands, East Wales.

00:17So here, temperatures have fallen away, a few dense fog patches. Scotland and Northern

00:22Ireland, clear spells I think will come and go because we've got areas of showers moving

00:25through. Nevertheless, where we do see some prolonged clear spells, a touch of frost,

00:30perhaps some ice and fog patches about first thing. But through this central swathe, well,

00:37it's a milder start because we've got a lot of low cloud courtesy of a stalled weather

00:41front bisecting the country. North Wales, parts of Northern England, continuing to see

00:46drizzly rain, most persistent across North Wales. Now, for Scotland and Northern Ireland,

00:52turns out to be a day of sunny spells and showers, the most frequent showers affecting

00:56the Western Isles and Shetland as well as Orkney. But further south, a lot of low cloud,

01:02whether you've got the foggy start or the grey start, it's going to be a fairly gloomy

01:08day. Limited bright spells, but there could be one or two as the cloud thins occasionally.

01:13The front across central parts, well, that tends to very slowly move south-eastwards.

01:19As it does, we can expect an increase in the damp weather across southern parts of

01:23England into the Midlands overnight. Further north, clear spells finally breaking through

01:28for North Wales. Northern England, a colder start to Wednesday here compared with Tuesday.

01:32Touch of frost in places. One or two showers just lurking around Irish Sea coasts and more

01:37especially Western and Northern Scotland seeing those showers continuing to feed in as well

01:42as the north coast of Northern Ireland. Wednesday, though, we'll see mixed conditions across

01:47the UK. A lot of cloud through the Midlands, East Anglia and the south with outbreaks of

01:52rain slowly trundling south-eastwards. Further north and west, skies are brightening, some

01:58sunshine coming through. One or two showers, relatively quiet day, 4 to 7 degrees for most.

02:05Into Thursday, well, the Atlantic starts to get its act together and that's because of

02:11this that's occurring at the time of recording. You may have seen the consequences of this

02:16cold spell across North America on the news and it is an exceptionally cold spell across

02:23Canada and the US. It's coming into central and eastern parts of North America but it

02:28will also have important consequences on the UK's weather and that's because as it comes

02:33south during Tuesday, it mixes with the much warmer air to the south and that fires up

02:39a very powerful jet stream, 250 miles an hour. That's going to flow across the Atlantic and

02:45it's going to, as is often the case, deepen these areas of low pressure and send them

02:50our way. The first ones to turn up sends the first band of rain through on Thursday followed

02:55by further wet and windy weather on Friday. In fact, look at the tightness of those isobars.

03:01It could cause some serious impacts in places and that's why we at the Met Office are keeping

03:06a close eye on this system. We have already issued a yellow warning for the risk of impacts

03:11most possible across Western Scotland and Northern Ireland. So, of course, we'll keep

03:16you updated on all of that and you can follow those updates on our YouTube channel. Bye-bye.
