This is the Met Office UK Weather forecast for the week ahead 13/10/2025.  A week of anticyclonic gloom for many of us as a stubborn high traps a thin layer of low cloud. But some areas will be more favoured than others to see prolonged cloud breaks.  Bringing you this week’s weather forecast is Aidan McGivern.

00:00Hello and welcome to the Met Office Week Ahead Forecast, a week in which many of us will

00:05be experiencing anticyclonic gloom.

00:09What does that mean?

00:10It means that an anticyclone or high pressure is sitting slap-bang over the top of the UK

00:15throughout the week ahead.

00:17And under high pressure, the air sinks, but when that happens, it can trap a thin layer

00:22of moisture or low cloud and in some places drizzle close to the surface.

00:27That's what we've seen over the last few days in places and that's what's going to

00:31continue through the next few days.

00:33Now in the summer months, the sun can be strong enough to lift that low cloud into the clearer

00:37air above, but in October, November, while the sun just isn't quite as strong, it doesn't

00:45give the low cloud that buoyancy and as a result, the low cloud remains trapped.

00:50But there's another mechanism for breaking up the low cloud and that is higher ground.

00:55We have seen some spectacular images of hills over the Pennines and the Scottish mountains

01:00poking above the low cloud into the clearer air above, extraordinarily low humidities where

01:06that happens, 4% recorded over the tops of the Pennines earlier this week and beautiful

01:13clear skies where that happens.

01:15Also, where the cloud breaks up over higher ground and leaves some gaps on the other side,

01:21West Wales, the southwest of England, Western Scotland, for example, prone to that sort of

01:25thing on Tuesday afternoon.

01:28But for many, it remains grey throughout Tuesday.

01:31The thickest cloud will be across the Midlands, the east and southeast of England, thick enough

01:36for again some drizzly showers in places, particularly parts of Kent where we have the cloud, 14

01:42to 17 Celsius.

01:43In one or two spots, 18 or 19 Celsius, for example, West Wales, parts of southwest England, central

01:49and western Scotland where we get lengthy clear skies.

01:54After the evening and overnight, where we do get those clear skies, a touch of frost and

01:58some fog patches to wake up to on Wednesday, but for most, we keep the overcast skies.

02:02It's another grey day on Wednesday.

02:05Again, favoured spots for that cloud breaking up western parts of Wales in the southwest,

02:11parts of northern Scotland, for example.

02:12Still some drizzly showers in the far north and the far east and southeast.

02:16Otherwise, many places dry, a little bit cooler compared with Tuesday, and Thursday, again,

02:21a little bit cooler.

02:22But it's roughly similar conditions.

02:25High pressure, rise on top of the UK, light winds for many, but we keep the low cloud not

02:31entirely cloudy everywhere.

02:33There will be breaks shifting here and there each day.

02:37And because it's a thin, fickle sheet of low cloud, it's very difficult to say exactly where

02:43those breaks will occur.

02:44But favoured spots, the far south, perhaps parts of central and northern Scotland again,

02:50although northern Scotland will be prone to some light showers from time to time.

02:54Some clear spells coming into Shetland by the end of Thursday and actually a much brighter

02:58day to come for Shetland on Friday as high pressure drifts to the north.

03:04Otherwise, barely an isobar on the map there across the UK.

03:08So another calm and settled day, but not entirely sunny.

03:11There will be sunshine.

03:13You can see where the cloud breaks up nicely, the south into western parts of England and

03:17west Wales, northern Scotland, for example.

03:20Perhaps a few more breaks, I think, on Friday compared with the week leading up to Friday.

03:25So a better chance of brighter skies.

03:27The low cloud sheet lifting a bit and ending up not quite as gloomy.

03:32A few drizzly showers still possible through the North Sea coast, for example.

03:36Otherwise, most places dry and settled if, again, rather cloudy, typical temperatures low

03:42to mid-teens.

03:44High pressure then starts to shift Friday night into Saturday.

03:48It's going to be a slow process.

03:50It moves into the North Sea.

03:52That means the winds will start to come in from the south.

03:54A bit more of a breeze now, a few more isobars on the chart, perhaps fewer mist and fog patches

03:59overnight where we get clear spells.

04:02And Saturday is another generally dry day.

04:04But the hints there in the Atlantic of a change.

04:07Through the weekend, weather fronts starting to knock on the door.

04:10A bit of uncertainty about the timings behind these weather fronts likely to arrive into

04:14the far west during the second half of the weekend could take all weekend to reach other

04:19parts of the UK.

04:20The far north may hold on to the high well into next week.

04:25So a little bit of uncertainty about how much the Atlantic will take over later this weekend

04:29as high pressure starts to lose its grip.

04:31We'll keep you updated right here on all the developments.

04:34Bye bye.
