00:00Hello, it was another cold start on Tuesday morning with a widespread and, in places,

00:05sharp frost. And it's going to be a cold day with Arctic air in place across the UK. However,

00:12compared with Monday, where we saw some heavy rain across southern parts and thick cloud,

00:16actually a bit more sunshine coming through and lighter winds may make it feel more pleasant.

00:21However, having said that, there will be some build-up of the cloud and it's not going to

00:26be entirely sunny because there will be an awful lot of cumulus and stratocumulus across the UK.

00:30One or two showers into Northern Ireland, perhaps North Wales, but those wintry flurries continue

00:35in the north of Scotland. Sleet, snow and hail. Accumulations negligible, however,

00:40and in between there will be some bright spells. A cold wind blowing from the north continues,

00:45seven Celsius there for Orkney. Out of the breeze, in the sunny spells,

00:5013 Celsius in the south, however, won't feel too unpleasant. Then into the evening,

00:55the cumulus and stratocumulus does tend to disappear. And as we go through the evening

01:02and overnight, we're going to see clear spells across central and northern parts of the UK,

01:06so another frosty one is expected. I don't think it will be quite as widespread because there will

01:11be thicker cloud layers moving in from the south-west and certainly towards the south-west,

01:15it's frost-free, eight or nine Celsius with some light outbreaks of rain into Cornwall.

01:21But where we get some breaks in the cloud for northern and eastern England,

01:24parts of Scotland, here low single figures or a few degrees below freezing in some sheltered spots.

01:30So another chilly start for the north and the east. We keep that cold air in place whilst

01:35these weather fronts turn up towards the south-west. They're coming in from the

01:39south-west, so a change in wind direction brings Atlantic air and that means we'll see

01:44greater increase of cloud and some outbreaks of rain moving in from the Atlantic, but also

01:49this milder air starting to make inroads. However, Wednesday is still a chilly day across

01:54the north and the east of the UK, still one or two wintry flurries. Mostly these will be rain

01:58and sleet towards the coast, hail and snow over hills. And there'll be some bright spells there

02:03for the north of Scotland, some sunny spells also for north Wales into the midlands, northern

02:08England, but a few showers will break out during the afternoon. The cloud will thicken for northern

02:12Ireland, some light outbreaks of rain towards the west here, but it's going to be a dull and

02:16damp day across south-west and south England as well as south Wales with the cloud covering

02:21the hills. However, here temperatures are rising, 14 Celsius in the far south-west,

02:27whilst we're looking at 10 to 12 fairly widely elsewhere and staying in the single figures

02:32in the north-east. Then into Wednesday evening, the thicker cloud towards the south-west. It's

02:38pushing its way north-eastwards, but it's making slow progress. I think a damp end to the day for

02:43western parts of northern Ireland, a few showers continuing for central parts, but also the dull

02:49and damp and gloomy conditions sticking close to Devon, Cornwall and Somerset as well as perhaps

02:56parts of south Wales. That cloud and those outbreaks of rain become more widespread across

03:02southern parts of the UK on Thursday and into Friday. They clear away through the weekend

03:07and the main trend into the weekend is for temperatures to rise up and down the UK.
