00:00Hello again. Whilst it was some southern parts of England and South Wales that woke up to
00:04snow on Wednesday morning, over the next 24 hours the snow risk moves north and escalates
00:09as it reaches parts of the North Midlands and Northern England. More on the amber warning
00:13for this region in a moment. But actually it's a slightly further south where we're
00:17likely to see some disruptive snow on Wednesday evening through parts of Wales, away from
00:22the far south of Wales, into the Midlands, parts of East Anglia, anywhere to the north
00:26of the M4 really, we could see a few centimetres of snow falling, as much as 10 centimetres
00:31over some higher parts. But much of that peters out by the end of the night. A lot of cloud
00:35across southern parts and some rain showers rather than snow into South West England and
00:40South Wales, along with a gusty wind by the end of the night. Much milder conditions here,
00:45frosty conditions elsewhere. Northern England, Northern Ireland, much of Scotland, temperatures
00:49well below freezing, minus 10 to minus 15 Celsius for Northern Scotland and further
00:53snow flurries here as well. Some icy patches to watch out for for Northern Scotland into
00:58North East England as we begin Thursday. The cold air firmly in place across the north.
01:03Mild air making inroads across southern parts of the country, in between an area of low
01:08pressure, strong wind circulating around that area of low pressure and a band of rain which
01:12is going to turn to snow across this boundary between the mild and the cold. And on Thursday
01:18that boundary really sits through central areas. So North Wales, North Midlands, Northern
01:24England and then later Northern Ireland. We're likely to see spells of rain and sleet predominantly
01:29at the very lowest levels and around coasts. Some patches of snow possible, but the main
01:34risk of disruptive snow is above 100 metres. So really it's for the North Pennines into
01:41the Peak District where we're likely to see that significant disruption. And that's why
01:47there's an amber warning. So in this general yellow area, I think at low levels, 0 to 100
01:53metres elevation, any snow will be patchy if at all. Around coasts there could be some
01:59rain or sleet rather than snow. But above 100 metres in the yellow area, the risk of
02:05a few centimetres of snow, as much as 10 perhaps in some spots. But in the amber area, and
02:11this includes places like Leeds, Sheffield, Bradford, Wakefield, the risk of 10 to 20
02:17centimetres of snow. And over some of the most exposed spots, 40 centimetres. So for
02:22some Trans-Pennine routes, very difficult conditions developing through Thursday and
02:27into Friday. Strong winds accompanying that snowfall leading to blizzards and drifting
02:31of the snow as well. And that's why there's an amber warning for the north part of the
02:37Midlands over higher parts into the Peak District as well as the North Pennines and some of
02:41the populated areas included in that amber warning. So that main risk area across central
02:48areas on Thursday. This is running the sequence through for Thursday again but covering the
02:52whole of the UK. Rain showers more likely for southern parts of England and South Wales.
02:56A gusty wind here as well. And also I suspect it will be rain around coasts of Northern
03:02Ireland and Northern England. But for southern Scotland, turning cloudy, a few snow flurries
03:06coming into the south-east of Scotland. More snow flurries for the far north of Scotland
03:11in between sunny spells and temperatures staying on the low side. Low single figures
03:16if not staying below freezing for some higher parts of inland Scotland, especially where
03:20we've got lying snow. Through Thursday night, what happens is the low pressure moves its
03:26way eastwards across the UK. So further rain showers to come in the south, further spells
03:30of snow for some of these central areas, especially above 100 metres. But the low pushes colder
03:36air southwards again, so the snow perhaps returning to southern parts of the Midlands
03:40and East Anglia as we begin Friday. And it's going to be a cold start, especially for Scotland
03:46and Northern Ireland again, but bright skies here. An increase in the snow showers I suspect
03:49for northern Scotland as well as parts of Northern Ireland. Then as the system pulls
03:54away, you wouldn't be surprised to see a few flakes of snow into East Anglia, perhaps the
03:59south-east because the cold air is pushing south at the same time. But it's all petering
04:03out at this stage and there'll be some brighter skies and some drier conditions following.
04:08Temperatures seven to eight Celsius at best in the south, mid-single figures or even low-single
04:13figures further north. But blue skies and the wind's easing, the precipitation dying
04:18away, so actually Friday's looking like a quieter spell before another weather system
04:22moves in for Saturday, perhaps bringing some further snow in places, especially northern hills.
