This is the Met Office UK Weather forecast for the next 10 days, dated 08/11/2023.

Low pressure and weather fronts dominate our weather for the next week or more, so we can all expect more rain. A gap in the rain should bring many places a fine day on Saturday with a frosty night to follow.

Bringing you this 10 day trend is Met Office meteorologist Alex Deakin.

00:00 It's the time of year where many different weather scenarios are possible.
00:04 Stormy weather, obviously, as we've seen, but also we could see high pressure and fine
00:09 late autumn sunshine and misty mornings.
00:12 Also the time of year where people start scanning for any cold weather and any whiff of snow.
00:17 I'm here to tell you that none of those three scenarios are particularly likely, but I can
00:23 guarantee there will be more rain in the next 10 days.
00:27 Here's the bigger picture, the view of the jet stream.
00:30 It's been particularly active recently and also particularly south shifted, taking low
00:35 pressure systems and wet weather across Spain and France, as well as bringing them towards
00:40 the UK.
00:41 Not a huge deal of change over the next five or so days, although signs of it weakening
00:47 a little bit as we head through the weekend.
00:50 But look at this, another ribbon high in the atmosphere of active, strong winds.
00:56 The jet stream barrels its way back towards the UK for the new working week, but it has
01:03 shifted a little further north.
01:04 And that is perhaps one trend that will continue through the next couple of weeks.
01:10 With the jet stream coming in like this, you know that means low pressure and that's what's
01:14 going to dominate our weather for the next several days.
01:18 Spiraling around us through the rest of this working week, then we'll see another tangle
01:21 of weather fronts, another low for Sunday and another one follows them behind on Monday.
01:27 These weather fronts will bring outbreaks of rain, but as you can see, they're always
01:30 coming in from the west.
01:32 So bringing reasonably mild air with them as they do so from the Atlantic.
01:38 Let's just rewind because there is a little gap, a brief respite, as you will, for Saturday.
01:44 We're not really in a ridge of high pressure.
01:46 We're in what's known as a cull, where you're between two areas of low pressure and two
01:51 areas of high pressure.
01:53 It's a kind of weather no man's land.
01:55 And that's where we are on Saturday.
01:57 But it does mean that most of us will have a fine day on Saturday.
02:01 Around this low, there'll still be a breeze coming in from the north and there's a hint
02:05 of blue on the chart.
02:06 There will be some frost around through this weekend.
02:09 And although there'll be a few scattered showers in the west, certainly initially, many places
02:13 on Saturday will have a dry and a bright day with some of that autumn sunshine.
02:19 As we go through Saturday night, however, be aware that it will turn pretty cold, a
02:24 more widespread frost for Sunday morning, with still a few scattered showers across
02:29 the far north.
02:30 Perhaps not as cold in the southwest because the cloud could be moving in here as we start
02:35 to see the next weather system coming in.
02:37 But as I said, for many, Saturday does look like a window of fine weather, but it will
02:42 bring with it that likelihood of morning frost and also some fog with light winds.
02:48 That's almost inevitable at this time of year.
02:51 So frost and fog through the course of the weekend.
02:54 And then as we head out to the west, this next weather system comes in during Sunday.
02:59 That will bring a spell of rain.
03:00 Some uncertainty about the exact timing of this as it moves in, but most places will
03:04 see some rain during the course of Sunday from this area of low pressure.
03:08 And then as we saw earlier, that's followed by another one bringing another spell of rain
03:12 likely across the country for Monday.
03:15 They will be bringing bands of rain, but they will also be bringing milder air.
03:19 So it turns a little colder in that cold through Saturday.
03:23 But as these weather systems come in from the Atlantic, as I mentioned, they're going
03:26 to be drifting and bringing with them relatively mild air from the west or the southwest.
03:32 So we'll start to see the temperatures rising as we go into it next week.
03:36 We'll look at that in a bit more detail in just a second.
03:39 But first of all, let's look at the rainfall, because it's all coming in from the Atlantic.
03:43 So it'll be western areas that bear the brunt of the rain.
03:46 And these two charts show the accumulation of rainfall over four days from Friday through
03:53 the weekend and Monday as well from two different models, from the Met Office model and from
03:57 the European model.
03:58 And then pretty good agreement that it's going to be western areas, these darker colours,
04:02 the darker oranges, particularly the hills that see the most rainfall with parts of the
04:07 east with the rainfall shadow not seeing as much.
04:10 So yes, we are expecting some wet weather over the next four or five days, but nothing
04:14 exceptional in these rainfall totals with those western hills really bearing the brunt.
04:20 What about those temperatures?
04:21 Well, as I mentioned, we will be seeing an uptick into the new week next week.
04:26 I picked Birmingham here to show the the meteorogram or the temperature trend.
04:30 I could have picked almost anywhere showing these red box and whiskers plots are below
04:35 the average line, which is this line here for the rest of this week.
04:39 But then they do jump up a little bit and it's turning a bit milder into next week and
04:43 the nights in particular.
04:45 That dip, as we saw, increased chance of frost through the weekend as those nights get colder
04:50 and colder than average before they also take an uptick and mostly above average throughout
04:56 next week.
04:57 So on the chilly side through this week and into this weekend and then turning milder
05:01 again for next week.
05:04 What about the rest of next week?
05:05 Well, it's likely to be dominated by low pressure.
05:08 This is the pressure trends from the multi model.
05:12 So when we run all the models many, many times, blue is low pressure.
05:16 The date's going forward along the top.
05:18 Previous computer model runs down the side.
05:20 So a strong signal here, a lot of consistency that, well, it's going to be low pressure
05:26 dominating as we've seen through the weekend, but also for most of next week.
05:30 The blues get a little paler as we go through the latter part of next week.
05:34 But still, it looks most likely that low pressure will be dominating.
05:39 Another way to look at that, and this is just from the European model, is to look at the
05:42 pressure anomaly or the pressure when compared to average.
05:47 And the bluey green colours here are when pressure is going to be lower than average.
05:52 And this is averaged over the whole of next week.
05:54 So from Monday to Monday through next week.
05:57 And you can see that across the whole of the UK, we're in the bluer zone.
06:01 So pressure is going to be lower than average and particularly lower than average up to
06:05 the northwest of the UK.
06:07 So again, just telling us that signal that low pressure is going to be in control and
06:12 that more likely than not, it'll be westerly winds, which means western areas are more
06:17 likely to see the wetter weather.
06:19 And that's what this is showing us.
06:21 This is the rainfall over that week from Monday to Monday.
06:25 And again, it's the anomaly compared to average.
06:27 So western areas see more rain than average anyway, but this is comparing it to those
06:32 averages.
06:33 So the darker greens in the west just suggesting that the west will be wetter than average,
06:39 even though the west is also the wettest part of the UK, if that makes sense.
06:43 So, yes, suggesting again that western areas will bear the brunt of the rainfall as we
06:47 go through next week.
06:49 And that's what we'd expect with a fairly active jet stream coming in from the Atlantic.
06:54 So it looks like the weather is going to be dominated by west or southwesterly winds for
06:57 most of next week, bringing further spells of rain.
07:01 How strong the winds get?
07:02 Well, that will be determined by the exact shape of the jet stream and how it wiggles.
07:06 So that's something we're keeping an eye on.
07:08 But generally, west or southwesterly winds bringing in spells of rain.
07:12 But it'll be western areas that bear the brunt of the rain as well.
07:16 And also temperatures are likely through next week to be a little bit above average.
