Much cooler weather is arriving.

Thanks to Sue for the photograph.

Tonight sees plenty of cloud, though more in the way of clear spells towards dawn. Down to around 9’C. Might be the first time I’ve slept with the window closed for some time.

For Friday we are in a northerly flow, with low pressure over Scandinavia and high pressure close to our west.

Sunny spells and fair weather cloud all day, one or two isolated showers, say a 20% chance of catching one – more likely late morning and lunchtime period. Much cooler in the notable northerly wind, 16’C. Mostly clear skies overnight and a chilly night, down to around 5’C.

Saturday sees fairly long spells of sunshine, though a bit of fair weather cloud around, and the sunshine gradually becoming hazier during the day. Still on the cool side for September, 16’C in a fresh northerly breeze. Some clear spells overnight, though quite a bit of high/mid level cloud, down to around 7’C.

Sunday should start with some sunshine, but a lot of cloud will develop and it will often be rather overcast from around late morning – though some bright spells still. A small chance of a shower, though most places missing them. 17’C in that fresh northerly breeze. Some cloud and some clear spells overnight, a small chance of some mist/fog forming, down to around 7’C.

Bank Holiday Monday looks rather cloudy. Some brightness at times, more likely early morning and the evening, but rather cloudy otherwise – a small chance of a light shower. Around 17’C. Probably rather cloudy overnight, down to around 10’C.

By Tuesday we’ve cut off the cool source of air with high pressure now over the UK.

Still a lot of cloud around, though some sunny breaks. Temperatures nudging up to 18’C, maybe 19’C with a bit more sunshine than currently expected. Some clear spells overnight, down to around 10’C.

Wednesday should see the dry weather hang on, though uncertainty on cloud amounts – likely more cloud than sunshine. Warmer, around 20’C.

Thursday is where confidence becomes much lower. Suggestions of a weather front trying to cross during Thursday – no idea yet as to whether it will be successful, or perhaps struggle against a build of high pressure. Probably warm though.

Friday and next weekend could be anything – wet, dry, sunny, cloudy, warm, cool – I’ve no idea yet. Maybe if I’m pushed then something showery with normal temperatures is slightly more likely – but I don’t know why I’m writing this.

Hurricane Fiona should be to the east coast of USA by this point, so this will make everything uncertain for a while.
