Two more hot days – then the thundery breakdown.

The forecast is going to be a bit vague for later in the week as these style of thundery breakdowns are not only uncertain right up to the moment in terms of where will get thunderstorms and where will get downpours – but are also uncertain in terms of what happens in the 2-3 days after.

Thanks to Fay for the glorious photograph.

Tonight will be mostly cloudy due to a very weak weather front that is spreading south-east slowly – remaining rather warm and humid, eventually down to 16’C.

Tuesday will be rather cloudy in the morning, though some sunny breaks too. Gradually sunshine amounts will increase – with long spells of sunshine by late afternoon, if not earlier. Still very warm, though a bit lower than today, 25’C. Mostly clear skies overnight, fairly warm and quite humid too, 15’C.

Wednesday is the last hot and sunny day of this spell. Long spells of hot sunshine all day, maybe some cloud later in the afternoon as the fun and games approaches. 28’C likely, perhaps more – and humid too. Late evening onwards will see showers spread up from the south – likely heavy or even torrential, thunder/lightning possible. A warm and muggy night, no lower than 18’C.

I stress again the uncertainty for this period!

Thursday morning may well still see further showers or general rain, likely heavy, thunder possible – when it clears is uncertain, it may have cleared by dawn or it may not clear until midday. Likely mostly cloudy afterwards, some bright spells possible – especially if the overnight showers/storms cleared quite early. Likely also still warm and humid, say around 22’C. Mostly cloudy overnight, still quite a warm and humid feel, down to around 15’C – a chance of showers by dawn.

Friday sees low pressure close to our south-east.

It isn’t certain, but most likely further showers or general rain spread up from the south-east. Lots of uncertainty – it could arrive anywhere from morning until evening, it could just be some showers, or it could be many hours of very heavy rain. Maximum temperatures anywhere between 15’C and 22’C. Showers/rain likely continuing into the evening and perhaps overnight for a time too.

Tentatively Saturday looks reasonable, with quite a bit of cloud but some sunny spells, and temperatures around 21’C. I state this with fairly low confidence though.

Either Saturday night or Sunday may see the next spell of heavy, possibly thundery showers moving up from the south – probably still warm or very warm.

Low confidence for next week, but suggestions that it will be cooler than normal and certainly of late, sunshine and showers.
