WARNING. This weather forecast is going to feature the word, “warm”, on multiple occasions.

Yes, high pressure is taking control at last, and things are going to warm up, perhaps becoming very warm. Not all so straight-forward there will be some cloud at times, and still one or two showers also.

And I’ve just realised – this will be our first warm spell since…September? I don’t count the two days at the end of March as a “spell”!

Thanks to Paul for the photograph. Well, two photographs.

Tonight sees fairly clear skies, down to around 5’C.

Thursday starts sunny. Plenty of pointless low-level cloud will bubble up by late morning, there will be a few sunny breaks – and increasingly so as the afternoon goes on, it should finish very pleasant. Just a very small chance of a light shower around lunchtime. Feeling warmer, around 18’C – perhaps a shade more. High cloud building overnight from the west, down to around 8’C.

Friday sees a weather front trying to push across from the west, but being slowly squeezed out of existence as high pressure builds. It means it will be rather cloudy but with hazy sunshine, occasionally cloud thick enough for the odd light bit of rain – possibly anyway. Fairly warm, 18’C. Fairly cloudy overnight, the odd spot of rain, around 10’C.

By Saturday high pressure is building more extensively – from the Azores through the UK into Scandinavia – a similar set-up as to much of spring 2020.

Still quite a bit of cloud trapped underneath the high from that decayed weather front, so likely that sunny spells will be outpaced by cloud amounts, and there will be the odd shower around – most likely not heavy. Warm, 20’C – maybe a shade more. Clear spells overnight, down to around 9’C.

Sunday will be sunny. It starts pretty glorious, some fair weather cloud will bubble up but less than of late – a very small chance of a shower. Warm, we should squeeze 22’C. Clear spells overnight, down to around 9’C.

Bank Holiday Monday again starts sunny. Fair weather cloud will bubble up, again a very small chance of a shower but another pleasant and warm day. 22’C, maybe 23’C. Clear spells overnight, some high cloud also – down to around 10’C.

Tuesday looks even warmer. Likely some high cloud around making it a bit hazy, but also less of the fair weather cloud. Very warm, 25’C is achievable. Clear spells overnight, down to around 10’C.

Wednesday is likely very similar – low pressure perhaps a bit closer to our north-west and a small chance of low pressure moving up from Spain, but most likely neither approaching by Wednesday.

Which means more very warm sunshine, perhaps into the quite hot category. Some cloud, but sunshine the main theme, temperatures somewhere between 24’C and 27’C.

Thursday probably stays very warm/quite hot, with sunny spells. Small chance of a thundery shower, it should be somewhere between 23’C and 28’C.

Things do become a bit more uncertain by Friday and into next weekend. The slightly more likely outcome sees high pressure remain in control but temperatures drop back a bit to say 20’C or so – a shower or two possible.

It may instead stay very warm – I would neither rule out a brief return to something cooler and unsettled – or rule out a short properly hot southerly, followed by a thundery breakdown.

I should get back to normal Monday/Thursday operations next week – this forecast is early as I’ll be travelling up north for “Christmas” tomorrow. A warm “Christmas” – feels almost as strange as a warm day in spring felt a week or so ago.
