00:00Welcome to your weather for the week
00:01ahead from the Met Office, a very
00:04different week this week compared
00:06to last week when it was all about
00:07strong winds and heavy rain.
00:09And most places across the country
00:12are going to have a dry week, an
00:13increasing chance of seeing some
00:15thickening fog patches.
00:17And after a frosty start for many,
00:19the nights will turn a little bit
00:21milder generally as the week goes
00:23on. But yes, dry weather for
00:25the majority, and that's because of
00:27an area of high pressure.
00:28And it's a big boy as well.
00:30This has been dominating the
00:32weather throughout the weekend.
00:33It will still control our weather,
00:35but as we run through the week, it
00:36does slowly start to drift
00:39away to the west.
00:40And as it does so, particularly
00:41through the middle of the week,
00:43weather fronts will start to drift
00:45southwards across the country.
00:46And then we're looking out to the
00:48northwest as this area of low
00:49pressure could be
00:51the start of a more significant
00:53change as we go towards the
00:55weekend.
00:56That's all to come, though.
00:57Let's get back to the nitty gritty,
00:59the details for this week.
01:00With high pressure in control, most
01:02of us having another dry day on
01:03Tuesday. I say most because there
01:05will be some rain at times across
01:07western parts of Scotland, maybe
01:08even Aberdeenshire, seeing a few
01:10spots. But a good chunk of the
01:11country having a dry day on
01:13Tuesday. It's going to start
01:14frosty across the south and
01:16there'll be some stubborn fog
01:18patches around as well.
01:19But once they've cleared, we should
01:21again see some sunshine here in
01:22northeast England, also seeing
01:24some sunny spells.
01:25Fair bit of cloud around, though,
01:26elsewhere with the help of some
01:28sunshine temperatures struggling
01:30up after that frosty start to five,
01:32six, seven Celsius.
01:33Again, it'll be mildest across
01:35Scotland, but it will be quite
01:37grey here with that rain across the
01:39Highlands and the Western Isles.
01:40There's the high pressure still
01:42close by as we go into
01:44Wednesday. This weather front just
01:45trickling southwards, though not
01:47bringing much rain, but certainly
01:49introducing more and more clouds.
01:51So it won't be quite as frosty
01:52on Wednesday morning, although we'll
01:54still see some across the south.
01:55And again, there could be some fog
01:57around. Now on Wednesday, there'll
01:58be holes in the cloud across eastern
02:00Scotland, northeast England
02:02that could allow temperatures to get
02:04up to 11, 12 degrees
02:06Celsius. But again, there'll be
02:07patchy rain across western
02:08Scotland. Most of the parts will
02:10be dry, but not as much
02:12sunshine across the south.
02:14Generally, that cloud increasing as
02:16we go through Wednesday and into
02:17Thursday means the mornings won't
02:19be as frosty, even though the high
02:21pressure is still controlling
02:22things. But it's just slinking
02:24further away by Thursday.
02:25And then this next weather front
02:27just toppling in over the top, that
02:29will bring a bit more cloud and rain
02:30over the Northern Isles, the Western
02:32Isles and western Scotland.
02:34Again, with the winds coming in from
02:35the southwest, we could see some
02:36sunshine across that far
02:38northeastern corner of the mainland
02:39and that could see temperatures
02:41again getting up to 11, maybe
02:4312 Celsius.
02:44For the majority, it's a
02:46grey day on Thursday, a lot of cloud
02:48around and more in the way of mist
02:49and fog, especially over higher
02:52routes. But it is also slowly,
02:53but surely turning a bit milder as
02:55well because we're not having those
02:57frosts overnight.
02:58So we're not starting as low
02:59temperatures by the afternoon,
03:01picking up to 8, 9, maybe 10
03:03Celsius. But of course, it won't be
03:04as sunny, so it won't perhaps feel
03:06as nice.
03:07The high pressure is well and truly
03:08gone by the time we get to Thursday
03:10night and into Friday.
03:11And this weather front will have a
03:12bit more about it as it slinks
03:14southwards during Friday.
03:15Some uncertainty about the position,
03:17but it will probably bring a band of
03:19cloud and rain across Scotland,
03:20Northern Ireland, perhaps into parts
03:22of northern England later.
03:23But again, across the south, it is
03:24looking largely dry on Friday and
03:26further north behind that cold front
03:28may start to brighten up, but
03:30it could also then start to turn
03:32a bit colder with temperatures back
03:33down into the mid-single figures
03:35as they will be quite widely across
03:37the country.
03:38As I said, some uncertainty about
03:39the position of that weather front,
03:40but it slinks southwards, clears
03:42away and then we're looking out to
03:44the west.
03:45Again, the position of this low
03:46opens to some doubt at this stage.
03:48We're talking four or five days
03:50ahead, but that's where the system
03:52is set to bring more of a change.
03:54Notice more ice bars across the
03:55charts on Saturday, while many look
03:57like starting the weekend dry
03:59may not end that way as that low
04:01could just be the first of many.
04:02This daisy chain of weather fronts
04:04and this is the jet stream showing
04:06signs of pepping up and perhaps
04:08turning our weather much more
04:09unsettled as we go into
04:11next week and the changeover
04:13happening this weekend as the breeze
04:14starts to pick up and many of us
04:16will finally see some rain.
04:18Before that, though, many of us will
04:20have a dry week.
