Cooler with more rain to come.

Thanks to Annalisa for the photograph.

Tonight sees a bit of a mixture, some clear spells at times especially this evening and towards dawn, but some cloud at times with a bit of rain. Down to around 6’C.

The set-up for Friday is broadly the same as it has been all week, with a high pressure block towards Scandinavia, stopped low pressure systems getting past the UK – with Wednesday night’s low pressure still hanging around.

Fairly sunny in the morning, cloud bubbling up though likely still some sunny spells at times for the rest of the day. A small chance of a shower, breezy, 11’C. Clear spells at first overnight though cloud thickening somewhat from the east later, down to around 2’C – a ground frost possible in places.

Saturday may start bright, but will tend to become cloudy as a weak weather front tries to push in from the east – perhaps bringing a bit of patchy lightish rain. A bit of uncertainty as to how far west it gets. Chilly, 8’C. Clear spells for a time in the evening and the first part of the night as a different weather front pushes in from the west – and it will bring a few hours of rain after midnight, some heavy. Down to around 4’C before the rain arrives.

Sunday looks fairly sunny. Some cloud around, a small chance of a shower, otherwise chilly but pleasant – around 8’C, maybe 9’C. Mostly clear skies overnight, though some cloud towards dawn – temperatures getting down to around 1’C, so a frost in places.

By Monday another powerful streak of the jetstream will be heading towards us, though a little further south towards Europe.

It may start bright but rain will quickly arrive and spread across during the morning – some uncertainty on when it arrives but a start time between 9am and midday should be roughly ok. And some uncertainty on how long it rains for – feasibly any amount between 4 and 10 hours. Some heavy rain expected. Reaching around 9’C and quite windy. Further showers probable overnight, down to around 3’C.

Tuesday is uncertain – it depends on where various low pressure systems and cut-off lows are, though the somewhat more likely outcome is that we stay dry with sunny spells – the less likely outcome sees further rain or showers. Around 8’C or so.

That’s about as far as I can go in terms of details, however I can tell you that it will be unsettled.

Wednesday and Thursday are likely to see further rain or showers, which could be heavy and there is a chance of strong winds. Temperatures probably up a notch, say 10’C or 11’C.

A suggestion of high pressure building from the south-west for Friday and into next weekend – but pretty low confidence really.

I still think high pressure building over the UK is the more likely outcome for December, but I’m wary of the jetstream being much stronger than I expected.

Should it happen, it may even be rather cold at times. Gosh, we might get a proper frost.

Next forecast should be Monday evening, as long as I don’t get too excited by a credible 0-0 draw with Iran in the World Cup.

See ya.
