00:00Hello there, welcome to your Tuesday evening weather update from the Met Office.

00:05Now wet weather will arrive across the western side of the country as we head through into

00:10Wednesday morning, all courtesy of an active jet stream which is allowing these areas of

00:15low pressure to develop and delivering them to the UK.

00:19You can see the strong winds of the jet stream just pushing down across the country through

00:24Tuesday into Wednesday and beyond.

00:27And that's the reason why the weather has been so mobile over the last few days and

00:31also wet at times.

00:33So on Wednesday morning, a yellow warning for rain kicks in from 9am across western

00:39Scotland.

00:40Expect 50-100mm of rain if not more over the higher ground and a real squeeze on the isobars

00:46so gales will develop as well.

00:49And these strong winds will extend down towards the Irish Sea from Wednesday and into Thursday.

00:53Currently though, through Tuesday evening, it's pleasant outside across much of England

00:56and Wales.

00:57Showers across north-west England, frequent bursts across Scotland with the odd rumble

01:01of thunder and we lose the shower risk across Northern Ireland around midnight.

01:05Showers become few and far between into the early hours of Wednesday morning across Scotland

01:10as well as the winds ease and clearer skies further south and east as we head into morning

01:16time.

01:17Temperatures then on the low side, it's going to feel chilly across Scotland and Northern

01:20Ireland, even rural spots across England and Wales, but notice waiting in the wings

01:24that cloud and also outbreaks of rain.

01:27However, first thing tomorrow morning, many areas getting away with a fine morning with

01:31some sunshine.

01:32It will be cool, at least though you'll see some brighter skies and then thickening cloud

01:37through the morning will eventually bring some outbreaks of rain to western Scotland.

01:41Rain then moves in across Northern Ireland, but it's not likely to pep up until probably

01:45mid to late morning.

01:47We hang on to some sunshine across eastern Scotland, north-east Scotland, much of England

01:50and Wales, although a few showers ahead of the main rain band across the north-west of

01:55England and the far north-west of Wales, but notice by lunchtime the rain has become persistent

02:01and heavy across western Scotland and then the winds pick up further strength, so expect

02:05some choppy seas, particularly across the western coast of Scotland, Northern Ireland

02:09and Irish Sea coast through the afternoon.

02:11We hang on to brighter weather from the midlands, mid-Wales, southwards, a bit blustery here

02:15even so, feeling pleasant in any sunshine, but notice this rain does extend towards

02:21Aberdeenshire up towards Orkney and Shetland through the afternoon, but persistent along

02:25that western side through the latter part of the day.

02:28Here are your temperatures, fairly low across Scotland and Northern Ireland, 16 or 17, we

02:32could squeeze a 23 across East Anglia, 20 for the eastern side of Wales.

02:38That weather warning extends into Thursday and again we'll see strong winds, if not gales

02:42for a time, and then another batch of rain moves in through Thursday night and into Friday.

02:48That clears off the scene, but it could linger on across the far south-east into Saturday

02:52and then notice still windy across Scotland into Saturday, further south we'll see some

02:57fine conditions coming through and a better day all round on Sunday.

03:02Before that though, on Wednesday night, that rain continues to be persistent and notice

03:07this driving southwest wind, bringing some mild conditions, but also strong winds across

03:12the north as well as the west.

03:14The winds then pick up across eastern Scotland through the night.

03:17That rain then extends into Northern England as we head into Thursday morning, lingering

03:22on into the afternoon, drier skies elsewhere, some showery bursts can't be ruled out though,

03:27and temperatures typically 17 to 20 degrees Celsius.

03:30And your outlook then as we head through to Friday, yes we'll see a lingering amount of

03:35clouds, even spits and spots of rain towards the south-east, elsewhere some showers in

03:38the mix, temperatures on the up a little bit.

03:41For more details check out our deep dive this week and tomorrow it's our 10 day trend.

03:45I'll see you later.
