00:00Hi there. During recent days, we've had high pressure centred over northern France

00:04and that's brought largely dry conditions to the south of the UK. All changed this morning.

00:09That high pressure has slipped away and the rain has returned across the south. Heavy

00:14in places and persistent through much of the morning, the rain finally eases into the afternoon

00:20away from the south east. But plenty of sunshine replaces that rain across England and Wales.

00:25Meanwhile, Scotland and Northern Ireland, well, we're going to keep the blustery north-westerly

00:30airflow and quite a number of showers feeding in, especially for western Scotland, parts

00:36of Northern Ireland as well. Those showers will be falling as snow over the hills of

00:39Scotland because this is a relatively cold airflow coming from the north-west, although

00:44temperatures not far from average this afternoon. Temperatures in some parts of the south will

00:49actually be falling through the day because we lose the mild feed as the cold front moves

00:54south-eastwards. Into the evening, we keep those showers going across northern and western

00:59parts of the UK. Some showers affecting Wales, north-west England and south-west England

01:03as well. But the bulk of the showers really moving into Scotland and Northern Ireland.

01:08More persistent rain turns up by the end of the night into western Scotland and Northern

01:12Ireland along with thicker cloud. The wind continues and with the cloud, the wind and

01:17the showery rain, most places will be frost free by dawn. But clear skies and some shelter

01:23from the wind in the south and south-east means that a touch of frost is possible here.

01:29Certainly a colder start compared with this morning. But plenty of bright skies for East

01:33Anglia, the south and south-east of England, so certainly better chance of blue skies as

01:39we begin Wednesday. However, thicker cloud will tend to affect many places by the afternoon.

01:44That cloud containing outbreaks of rain. Initially, there could be a few flakes of snow over these

01:48Scottish mountains as the rain moves in, but this system that's bringing the cloud, the

01:53slight change in wind direction and those outbreaks of rain is bringing also some milder

01:58Atlantic air. So back in the double figures fairly widely by the afternoon, although the

02:03north-east of Scotland staying relatively cold. Then those outbreaks of rain continuing

02:09into Wednesday night before eventually being replaced once again by a showery north-west

02:14of the airflow. But watch this. This area of low pressure heading into Scandinavia is

02:19unusually low for the time of year. This area of high pressure is unusually high and

02:24as a result we've got this set up with a very marked pressure gradient, very tightly packed

02:29isobars in other words, and widespread gales, especially across the northern two-thirds

02:35of the UK, particularly strong winds in the north and north-west around coasts and hills.

02:41So yellow warning in force. You can find the full details about that on the Met Office

02:44app and website and we'll keep you updated right here on the Met Office YouTube channel.
