Friday 23rd May 2025

A mixed bank holiday weekend ahead – but there is some sunshine in the mix.

Thanks to Christel for the photograph.

So the general picture sees a notable change from recent, high pressure still ridging across the UK, but now sourced from the south-west instead of the north-west – and low pressure out in the Atlantic is about to roll across.

Friday starts sunny, cloud will bubble up through the morning and through the lunchtime period likely there is more cloud than sunshine overall. Sunshine amounts increasing as the afternoon goes on, though also becoming hazy as high cloud spreads across from the west, as the weather system approaches. Around 19’C or so, with a bit of a breeze in the afternoon. Cloudy overnight, some outbreaks of rain from around midnight onwards. Around 12’C.

Saturday starts cloudy with some outbreaks of rain. This will clear east fairly quickly to leave a mostly cloudy day, quite breezy, some occasional bits of sunshine, some occasional bits of light rain/drizzle. Quite warm and a little humid, around 20’C or so – maybe 22’C if there is a bit of sunshine in the afternoon. Further showery outbreaks of rain arriving in the evening and overnight, though I stress the showery nature. Quite windy too, down to around 12’C.

Sunday will be quite a reasonable day. A chance of some showers first thing, but mostly a case of sunny spells and fair weather cloud from mid/late-morning onwards. I cannot totally rule out an afternoon shower but more likely it stays dry. Breezy and just about getting to 20’C. Some cloud, some clear spells overnight, down to around 9’C.

Bank Holiday Monday starts quite sunny, but cloud will bubble up during the morning with some scattered showers. Generally becoming cloudier as the afternoon goes on, further showers possible, or perhaps general showery rain. Around 18’C and windy. Some rain or showers overnight, probably dry by dawn and around 12’C.

By Tuesday, low pressure remains in control, centred to the north of Scotland – though high pressure will be attempting to nudge north from the Azores.

Rain is going to spread across on Tuesday, some uncertainty on the timing though. More likely a bright start with some sunny spells, with the rain arriving in the afternoon – though a smaller chance instead that it arrives in the morning. Reaching somewhere between 16’C and 19’C, depending on how much sunshine we get before the rain arrives, quite windy too. Further rain likely in the evening and/or overnight, timing uncertain, quite possibly heavy this time.

That’s as far as I can go in terms of details – even Tuesday is quite uncertain in terms of the timing of areas of rain.

Probably some rain at some point on Wednesday.

Thursday and through the weekend, still some weather fronts likely crossing though with high pressure to our south having more influence, these will be weaker affairs with lighter rain, and there should be sunshine at other times.

Probably warmer from Thursday onwards too, low, perhaps mid 20’s – a small chance of it becoming quite hot.

The changeable theme more likely to continue for the start of June, though short hot spells could also be part of this changeable theme.

Chances of something more settled for mid-June, say week 2 onwards.

Have a pleasant weekend.
