Back to rain, back to reality.

Thanks to Sarah for the photograph.

We start the week with a thundery low that developed over Spain/Portugal last week – and there is the next system developing out west too.

Monday starts cloudy with outbreaks of rain, heavy at times. This will very slowly edge west, though whether it clears Reading properly is 50/50 – before pivoting and heading back west later. If is does clear west then sunny spells are possible for a time this afternoon, with the odd shower – but it really is 50/50 as to whether it does, or it stays cloudy with showery rain. During the evening, timing uncertain, the area of showery rain heads back east once more – the odd heavy burst still mixed in, but generally it will be starting to fade, and it will be dry by dawn. Around 16’C by day. 13’C by night.

Tuesday looks rather cloudy, especially in the morning – one or two light(ish) showers around too. Some more bright/sunny spells later in the afternoon, and reaching around 18’C. Fairly cloudy overnight, a chance of one or two showers spreading up from the south-west in the latter part of the night towards dawn. Around 11’C.

Wednesday looks fairly cloudy as the next low pressure system develops and heads our way. Some showers during the day, though likely also some hazy sunshine at times – reaching around 16’C, maybe a tad more. Heavy rain spreading up from the south-west in the evening, more likely arriving around 6/7pm, but could be a couple of hours either side. Heavy rain continuing at times overnight, around 13’C.

Low pressure still in charge on Thursday – and cooler weather will be ready to spread down from the north again too.

Most likely Thursday sees some sunny spells but lots of cloud and a fair few heavy showers, potentially with thunder. A small chance instead that we remain under a band of rain – but this should be further north than here. Around 17’C and breezy at times. A chance of some showers overnight, and the cooler air starts to spread south, down to around 8’C.

Friday most likely starts cloudy with some bits of rain as Wednesday night’s weather front sinks back south-east. At some point it will be replaced by sunny spells. Feeling cooler in the northerly wind, around 14’C. Mostly clear skies overnight and becoming chilly, down to around 3’C.

Saturday sees a ridge of high pressure settle things down – some good spells of sunshine, a bit of cloud developing but a pleasant day – if on the cooler side at 14’C. A chilly night probable, though how chilly will develop on the level of cloud cover as the next low pressure system approaches – it could be down to anywhere between 2’C and 8’C.

Sunday sees the next low pressure system approach, but we probably get away with a dry and fine day with hazy sunshine and temperatures around 15’C – though fairly low confidence. Then heavy rain and strong winds move in for the evening/overnight.

Next week likely starts showery – but there’s a fair chance of high pressure building over the south of England to settle things down, with some warmish weather possibly spreading up from the south too.
