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.

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?

Don't know but not long to wait to find out

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

And/or it's rotating its fronts north eastwards

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.

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?

@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.

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.

That's what I mean in a way...it is exciting that we do not truly know....I have no clue

It's moved across the channel really fast, looks almost at my location already. I might have to get out of a very warm bed and check for snowfall in a minute.

 

[easton888]

Is it supposed to stall over the South of Britain? It's moving up so fast it looks like it'll be past London by 6am!

Could it stall over the south and the south east instead of just the south

the snow has stopped here now, it's just cloudy. i wonder will it clear up before the precipitation from the low gets here? or will it just suddenly starts snowing again?

Looks like the low isn't leaving the channel?

Is this going to be a repeat of March 2013 all over again?

Yep... there's a fairly intense area of snow off the Kent/E Sussex coast that's been stationary for nearly an hour.
