Hello from hot and sunny Ljubljana! Some notable warmth, sunshine and possible thundery downpours in the mix back home over the next few days.

Apologies for the lack of forecast so far this week, I had virtually no wi-fi in my previous place so it was impossible. This will likely be a slightly shorter forecast than usual as I have a lake to go to – and exact details are quite uncertain.

And thanks to Louise for the photograph.

So the general picture right now sees an area of high pressure over the UK, but with low pressure to the west – which is dragging up much warmer air, but also brings instability.

Today starts with a fair amount of cloud around, but it will gradually break up and by the afternoon there should be good/long spells of very warm sunshine. Reaching around 25’C, maybe a tad more. Mostly clear skies overnight though high cloud building later, down to around 13’C.

Thursday starts bright and warm. Later in the morning a weather front will push across, bringing some showery and probably heavy rain, perhaps a little thunder too – however the showery nature does mean there is a small chance of staying dry, and just being mostly cloudy for a time. Most likely any rain will clear mid/late afternoon onwards to leave more very warm sunny spells. Somewhere between 23’C and 26’C, depending on exactly how the day pans out. Mostly clear skies overnight and quite a warmish feel, 15’C.

Friday starts with sunny spells and some cloud. Rather hot and humid, most likely somewhere between 26’C and 28’C, though I wouldn’t rule out a 30’C. Showers possibly breaking out in the afternoon, but more so we are looking to the evening with a moderate chance, say around 40% of importing some significant thunderstorms from France. Where exactly they will track is uncertain, so they may well miss totally (more likely to miss than hit as it stands) – but if they so head our way, expect torrential rain and potentially copious amounts of lightning. A warm and humid night, no lower than 17’C.

Further heavy, thundery showers possible to start Saturday, but gradually this will move north to leave good sunny spells for the afternoon. I wouldn’t rule out an afternoon shower. Around 22’C though very give and take.

Sunday should be broadly pleasant as high pressure builds once more, sunny spells, variable amounts of cloud – though around a 40% chance of a heavy shower or two. Around 22’C.

More likely next week sees high pressure continue to build, so plenty more settled and fairly sunny weather, though the odd shower or weak weather front will be possible.

Models again hinting at a build up of heat later next week, so don’t be surprised if we end up in the high 20’s or even low 30’C by late next week or into next weekend. Something to watch but not yet expect.

I wouldn’t even rule out the June temperature record being broken.

Not sure when the next forecast will be, maybe Sunday morning, as I shall be back then, but if I get the time on Friday then I’ll do a thunderstorm update (thankfully my flight is in the morning that day!).
