It’s time to go easterly.

All change as the jetstream powers down, and the high pressure block to our north-east which I have kept mentioning in recent weeks, extends its influence westwards, towards the UK.

Which means it will be colder (somewhat) and drier than it has been.

And it gives us opportunities for snow and/or proper cold as December progresses – though there are plenty of other options available at that timeframe. Will just be nice to have a frost in my opinion!

Thanks to Chris for the photograph.

Tonight sees scattered showers quickly fading, mist and fog developing quite widely – low cloud at the least for all. Down to around 5’C.

Tuesday will be dull and cloudy for much of the day – early mist and fog will lift to low cloud. Some limited sunny spells possible later in the day. Mostly cloudy overnight, a few clear spells in places, some mist/fog patches though less widespread than Monday night. Down to around 4’C.

By Tuesday, we see an easterly flow just starting to pick up as the Russian/Scandinavian blocking high nudges west – low pressure systems heading far to our south, through the Mediterranean.

Wednesday starts mostly cloudy, perhaps some mist/fog patches though not so likely. Some sunny spells will develop at times in the afternoon, though the general theme is cloud – a small chance of a few spots of light rain/drizzle. 8’C. Generally cloudy overnight, mist/fog forming in some places, down to around 4’C.

Thursday again looks rather cloudy, some early mist/fog patches. Some sunny spells developing in places – there’s a bit more scope for sunshine on Thursday, but don’t be surprised if it stays cloudy and dull all day. Around 7’C. Mostly cloudy overnight, mist/fog patches forming in places, an outside chance of a passing light shower. Down to around 3’C.

Friday sees some subtle changes, as the easterly breeze picks up. Still plenty of cloud, some sunny spells, a small chance of a shower. Around 6’C but feeling quite cold in the breeze. Some cloud and some clear spells overnight, a small chance of a passing shower, down to around 3’C.

Saturday is very similar, plenty of cloud, some sunny spells, a small chance of a shower. Around 7’C in the fairly cold easterly breeze. Some cloud overnight, some clear spells, a small chance of a shower and down to around 2’C. A small chance of frost or fog.

Suggestions that Sunday will be cloudier and colder – maximums around 4’C, maybe 5’C. A little brightness possible at times, the odd light shower also possible, and still the easterly breeze. Fairly cloudy overnight, down to around 2’C – a chance of frost or fog.

These fairly cold and fairly cloudy conditions likely continue for the start of next week – fog or frost will be possible overnight, light showers also possible, though details will be determined much nearer the time.

By time we get to midweek, there are a wider range of possibilities – one of those involves low pressure moving up from the south, which could bring something less cold with some rain, though it could also lead to a battleground scenario with some form of snow event – maybe rain turns to snow, snow turns to rain, etc – one of those nightmare forecasting scenarios.

Or maybe we just stay as we were – fairly cold and fairly cloudy.

The slightly more likely outcome for next weekend into the week after, sees either northerly or north-easterly flows, which means it could be proper cold – and any precipitation will be more likely snow.

It may well be the coldest December since 2010 – though unlikely that exceptional. Not the best timing to have a cold December either…but weather will do what it does.
