00:00Hi there, with cloud-free skies for the vast majority this week, temperatures have been
00:04rising day by day and the heat continues to build for the last day of April and the first
00:08day of May. Widely sunny skies across the country, just some patchy high cloud across
00:13Scotland and Northern Ireland and the chance of the odd shower developing as the afternoon
00:18progresses for Northern Ireland and parts of Northern Scotland. Otherwise it is another
00:23warm or very warm day across many parts of the UK. I think for Scotland and Northern
00:28Ireland temperatures will widely reach the low to mid-twenties and it's worth noting
00:33that the April temperature record for Northern Ireland is 24.5 degrees, that's possibly under
00:39threat for Wednesday afternoon. Likewise the Welsh April temperature record is 26.2 Celsius
00:47and that is also under threat. But the UK national April record 29.4 Celsius, unlikely to be broken
00:56because temperatures more likely to reach 27, perhaps 28 Celsius somewhere between London
01:02and Bristol. However, widely we're expecting the mid-twenties through much of central and
01:08northern England into parts of Wales and in places 26 Celsius as well. But either way it
01:15is a very warm day to come across the majority of the UK. However, some changes are taking place
01:23as we go into the evening. A cold front starts to move into the north and north-west of Scotland.
01:27That's going to bring some showery rain with it and some thickening cloud layers. As that arrives
01:32it's going to keep temperatures elevated through the night across parts of Scotland and Northern Ireland.
01:37Elsewhere temperatures will be very variable overnight in some sheltered rural spots, dipping as low as
01:43the low single figures. But in urban areas, perhaps the mid-teens and in some parts, for example coastal parts of north and west Wales,
01:52temperatures could hold up at 16 or even 17 Celsius. Remarkably warm for the first morning of May.
01:59But big temperature contrast by the time we get to the afternoon as this cold front sinks south.
02:04It's going to bring showers to Scotland and Northern Ireland during the morning and by the afternoon as it pushes into southern Scotland and northern England,
02:12the chance of the old thunderstorm developing on that. Also, as the heat builds across parts of central England and Wales,
02:19the chance of the old thunderstorm developing later in the afternoon. Very isolated, most places staying dry and very warm or hot in places once again.
02:2829 Celsius, the most likely afternoon high for the first of May. And that again, London to Bristol, the hot spot.
02:36But it's a significant cooling off across Scotland and Northern Ireland as the cold front comes south. Low to mid-teens more likely and showers pushing into the northwest of Scotland as the day goes on.
02:48A couple of showers further south as well because of the remaining heat, but it's all changed going into Friday and the weekend.
02:56Some heat lingering in the far southeast on Friday. That's all gone by the bank holiday weekend.
03:01Despite cooler weather expected, it's still going to be largely settled on Saturday, Sunday and Monday.
