Monday 19th May 2025

Still some pleasant weather around this week, but more in the way of cloud, and some shower chances too. And the bank holiday looks mixed.

Thanks to Suzanne for the photograph.

We start the week with the omni-present high pressure that has controlled our weather for most of the recent months now towards Iceland, the easterly flow continues.

During the course of the week this high weakens and drifts further away, high pressure tries to build from the south-west but also low pressure tries to head in from the north-east – neither will win.

Monday starts cloudy. It will take some time to shift, late morning at best though more likely not until early/mid-afternoon, but eventually there will be some good sunny spells. Around 18’C in a light easterly breeze. We lose the easterly flow overnight so the cloud probably doesn’t return, at least not to the same level, some cloud possible but more in the way of clear skies – around 8’C.

Tuesday starts mostly sunny. It will stay reasonably sunny all day, though high cloud will tend to build making it hazy, and some fair-weather cloud later in the day too. Warm, 22’C. Cloud thickens overnight, a little patchy rain possible towards dawn, around 12’C.

Wednesday starts cloudy with some patchy light/moderate rain in places. This will clear south to sunny spells, say around midday but that’s very approximate. Once the sun comes out, some scattered heavy showers will break out, very possibly thundery, during the afternoon and into early evening. Around 18’C, give or take. Mostly clear skies overnight, down to around 6’C.

By Thursday we are caught between low pressure to our north-east and high pressure trying to move in from the south-west. Neither will be the eventual winner – that is the low pressure starting to gear up closer to Canada.

Some uncertainty on details for Thursday, more likely a sunny start, but with an area of cloud then moving south during the day – whether it is completely cloudy or somewhat cloudy is uncertain. Perhaps a little rain but nothing much. Temperatures roughly around 16’C to 18’C. Fairly clear skies overnight and a chilly night – down to around 3’C.

Friday starts sunny. Likely quite a lot of cloud bubbles up from around mid/late-morning onwards, more cloud than sun but still some sunny spells. Around 18’C or so. Cloud slowly thickening overnight, down to around 8’C.

Then the weather changes, just in time for the bank holiday weekend. It’s the return of autumn, as low pressure moves down from the north-west.

Timings uncertain at the moment, but at some point on Saturday a band of rain will cross – feasibly it could arrive any time from 6am to 9pm, there is quite a broad range as it stands. Probably quite slow moving, so 8-12 hours of rain when it does arrive, though it could be quite patchy and nothing especially heavy is expected. If it doesn’t arrive until late in the day, then perhaps some bright and warmish weather to start the day, but if it does then expect a cool day. Quite windy, though nothing unusual.

Sunday probably looks OK (ish), some cloud, some sunshine, perhaps some showers – around 17’C.

More likely Bank Holiday Monday isn’t too bad either, some cloud, some sunshine, some showers possible – though certainly a chance of a weather front later in the day bringing something cloudier with some rain. Around 16’C.

As I mentioned, details are still a bit sketchy – definitely not any glorious sunshine, but probably not a washout, just very middling weather.

Next week likely sees further rain/showers and wind at times, though a small chance of a short hot spell later in the week, or for next weekend – one to watch but not expect.

Changeable will remain the theme for early June, but some of those changes could be short hot spells followed by thundery downpours.

Happier times for farmers and gardeners I guess!
