00:00Hello, this week we will be at the tail end of an active jet stream which will send low

00:05pressure after low pressure towards the UK, but those low pressure systems will bump into

00:10high pressure to the east. As a result the isobars will squeeze together particularly

00:14through the North Sea and the Northern Isles and we'll often see spells of rain replaced

00:17by showers and very strong winds at times. Now the first area of low pressure that we've

00:24seen affect our weather this week pushes its cold front into central parts of Scotland,

00:29a gloomy and damp night to come here, cloud clearing the east of England though. Clear

00:33spells for a time, temperatures dipping to 5 to 8 Celsius perhaps with a gap between

00:38weather systems, but towards the west the next bout of wind and rain moves in and this

00:43will be persistent and heavy at times, certainly more rainfall associated with this than the

00:49first system that is diminishing as it pushes east. Where we get the wind and rain moving

00:55in from the west, temperatures will stay in the double figures, but it's a certainly

00:59wet start for southern counties of England, south Wales could be some issues, 30, 40 millimetres

01:04particularly over some of the higher parts here, Dartmoor and for example the Brecon

01:10Beacons. But the rain does push through, it moves into the north east where it tends to

01:15become slow moving and for eastern Scotland in particular accompanied by this strong wind

01:20it will pile up over the Grampians, 50, 60 millimetres, that could cause some issues

01:25later in the day for Tuesday. Either way it certainly brightens up behind the rain, Northern

01:30Ireland seeing a fine day with sunshine, but Wales and the south west quite quickly see

01:36showers arrive along with this stronger wind, coastal gales and so on. The gales developing

01:41in the Northern Isles will be particularly significant especially for Shetland, 50, 60

01:47mile per hour wind gusts, perhaps even more as we go into Tuesday night and Wednesday,

01:52the rain reaching Shetland during the early hours of Wednesday along with that very strong

01:56wind. Elsewhere across the UK it's clear spells and showers, the showers preferentially affecting

02:02western and southern coasts, but most areas seeing the odd downpour as we start off Wednesday.

02:09And it's not going to be that cold as we start Wednesday because of the strong breeze, but

02:13it will be a bit fresher compared with recent mornings. Northern Ireland seeing some fog

02:17early on, that clearing to sunshine and then for most it's a day of sunny spells and showers,

02:21the showers mostly affecting western areas, not that many in the east, so largely dry

02:26in the east, but the rain and wind continues for Shetland and gales or even severe gales

02:32is possible during Wednesday. Temperatures edging down over the next few days, but still

02:37a little above average, 13 or 14 in the south, 11 to 12 further north. Then towards the south

02:43west, the next system comes along, more wind and rain arriving on Wednesday evening associated

02:49with this, that spreads across the country during Thursday, clearing to sunny spells

02:53and showers and Friday also sees a mix of sunny spells with showers mostly in the west.
