Two calm days to come but then all change – wind and rain to welcome 2025, followed by an Arctic blast.
Photograph again comes from me of the gloom in Hull over Christmas…though you could pretend it is Reading, as you cannot really tell.
So the general set-up sees high pressure still dominating over Europe to our south, but low pressure systems are developing to our west.

Monday starts cloudy, shock horror, but it should break up at times to allow a bit of sunshine – mostly this afternoon. Around 9’C so not as chilly as it has been. Also becoming breezy. Mostly cloudy overnight, perhaps a spot of light rain/drizzle and down to around 7’C.
New Year’s Eve will be rather cloudy, but at times the cloud should thin to allow some hazy sunshine – always that higher layer of cloud. Becoming windy, and mild at around 11’C. Cloudy with strong winds overnight, perhaps some bits of light rain but the main weather front unlikely to shift this far south until the next day – still around 11’C.
New Year’s Day starts cloudy and windy, with the odd bit of rain. During the morning the winds will strengthen further to around gale force, and rain will arrive more likely from late morning, exact timing TBC and could easily arrive any time from around 9am, or maybe not until 3pm. The rain heavy, probably around 4-6 of rain, and it looks like there will be a squall band embedded, so 20-30 minutes of very heavy rain and really squally gusts of wind. Mild, 12’C. An outside chance of something wintry as it clears – but more likely it clears before cold air arrives. Winds easing as the rain clears, and skies gradually clear overnight – a frost possible, temperatures down to around 1’C, though a bit give and take.
By Thursday, high pressure is to our north-west and Arctic air starts to spill down.

It will be a mostly sunny day, a bit of cloud around and a very small chance of a stray wintry shower – but otherwise cold and sunny in the northerly breeze. Around 3’C. Clear skies overnight with a sharp frost. Easily down to -4’C, maybe even lower.
Friday again sees sunshine all day, a bit of cloud possible but mostly just pure sunshine – if rather cold. Reaching just 2’C, maybe 3’C. Clear skies likely for most of the night, though a chance of some mist/fog/low cloud forming by dawn. Down to around -3’C, but could easily be a couple of degrees either side.
By Saturday we start to see low pressure systems try to head our way – one from the north which would extend the cold spell if it wins, one from the south-west which could bring widespread snow, but more likely it would end the cold spell.
Too early to know which will win, but my money would be on the one from the south-west. For Saturday itself, low confidence but slightly more likely we remain in the cold and dry air, sunshine likely, though perhaps hazy by this stage. And again around 3’C at best.
And then from Saturday night into Sunday, well, highly uncertain.
The slightly more likely outcome would be for low pressure to head up from the south-west, bringing rain, much milder air and strong winds, though perhaps preceded by disruptive snow for a couple of hours.
The slightly less likely outcome would be for showery rain, sleet and snow to spread down from the north – this would also lead to an extension of the cold spell into the next week.
Less likely still (but possible) would be for the low pressure to come up from the south-west and kind of slide across the south of the UK, bringing snow, possibly disruptive levels, and we stay cold.
Or maybe neither low pressure quite makes it, and we just stay cold and dry.
Roughly a 35/30/25/10 chance split of the 4 broad outcomes, in my view.
So a very interesting time ahead for weather forecasting, and for those that want snow…well…there’s a small to moderate chance next weekend.…
