Wind howling round the house! Temp -5c, dew point -9c

Used to tracking French blobs on the radar but it’s usually summer and in the 20’s, not sub-zero and winter!

Officially signing off from my Perch by the window. Have a great year -  Enjoy it with your Families- Current pic - 4.5 inches    my favourite pic - Cheers All

So this is it, the end of winter. Time to look forward to Spring..... Wait, what's this?        Apparently not. So for the time being, we will remain as one for this cold spell. Ple

Just popped in to wish my southeast friends lots of snow, the radar looks very active so you should do well and that includes the coming days!..you deserve this

Is it me or are those the wind directions at the moment? Because that is how the animation plays out, UK ENE winds and France SW winds, almost a split right along the channel ?

The bands of precipitation are moving approx north east wards, but the winds will generally be east or south easterlies, at least in northern france. Looking at the sky an hour ago in West Sussex, the highish clouds were moving approx in an easterly direction, against an easterly wind,  indicating the movement of approaching weather systems from an approx westerly direction.

hi stubbys the French band gives impression of winds going NE but is illusion. the low is moving up in a north easterly direction from bay Biscay, the band of snow on its front is actually being blown in WNW direction as below, but on radar we see the north east edge of low coming up towards us each frame which gives the ilustion of showers going in north easterly direction. ETA for band to hit south coast 3:30am heavy stuff to arrive 7am ish.

That doesn't make sense unless there's a low in the channel right now.

Ah ok, thank you, so it' actually the low that is moving in a NE direction and not the precipitation? Thus giving the false illusion on the radar?

Going straight to the wire this whatever happens it’s going to very exciting. Judging by radar sequence the fact that some parts of SE are not even yellow, I’m seriously iffy on.

@pages on a side note, that chart you posted looks more like one of those paintings I would do at dreamland years back. Paper placed on some spinning thing and then you squirt on different colours of paint. You end up with some sort of marbeled psychedelic picture ? Thats how shallow my knowledge is at the moment on chart reading

yep correct the low is moving up in north east direction the precipitation flows around the low. centre of low is still miles out to west of Spain but moves up towards Biscay for tomorrow pushing the front on its north east edge up towards us.

@stubbys the colours  are the upper level winds speeds in KPH, these winds steer the clouds and of the precipitation. the lines with the arrows show which direction.

Very light snow here now for the last hour. is this associated with the low or is it just weak showers coming in off the north sea?

Have you noticed it’s been around for many hours? Just convective clump of showers..

 @Bricriu the remains of the streamers early on still giving light showers across London. 1am radar update looking good low and associated precip now around 50 miles north east of HIRlam modelling at this time. looking really could for all in south tomorrow. believe it or not central London currently looking the sweet spot that will have the Met office worried when they wake up!!

Can't believe they don't have night people that could issue warnings haha


Would be nice if central London could for once be the sweet spot and not be on the periphery of snow areas.

I think I made a good assumption with Emma! This could really caught people out.

It's a watch the radar and see type of game.......the low has still yet to truly bump into the very cold air mass....it might weaken as its slowed in movement

It’s well ahead of where GFS had it.

edit: grammar
