South East, London and East Anglia regional discussion - 8th February onwards

Sunset is not that far off now, we should see accumulation building.

Is it possible that the precipitation leaving the continent will intensify over the sea and (IMBY perspective) reach the far south eastern areas of our region?  

 

 

 

It looks like it divulges into a showery mess from modelling on UKV.

I don't get how that is melting - maybe your area is above freezing?.. or maybe there's a lot of heat coming off your house 

0C here and snowing, and nothing melting... the snow is, however, being blown into drifts, leaving other areas almost bare.

You laugh but just outside my French doors snow doesn't lay.. I try and park my cars facing the house as it doesn't tend to freeze as much lol

Yeah my mum used to put her tender plants close to the house walls to minimise the damage as it's always warmer.. Areas with a lot of buildings are always warmer.

Snowfall forming all around Sussex but are the downs going to slow it's progress towards the Brighton & Worthing area?

I'm struggling to understand this. You mean the 500 hPa temps are -28c? You want a large negative difference between the two and to be honest, you would use a lower down height than 500 hPa because no cloud top in winter will be that high. 

Obviously a colder 500 hPa level implies also cold lower down at 700 hPa ish, but not always!

Edit: The post on the next page with the Herstmonceux tephigram illustrates this perfectly, big chonky inversions. To be honest, it's probably why 850s have become so widely used in winter, because it's roughly where cloud tops from convective easterlies will be, so you can have a rough guide to instability. 

Both 500 & 850 hPa's at low temps -28C +/- will create instability allowing the ppn to perk up a lot more

If your snow depths are not as you had hoped for. Next week could well deliver. What temp is that aloft in E Anglia ??

Nope it’s nearly -2c here 

Beautiful powder snow this morning turning to big snow flakes this afternoon, we now have wet roads and paths. 
just grassy surfaces with cover and it’s still snowing heavily 

Maybe someone can explain it then cos i'm confused as it shouldn't be melting at that temp. We have had no melting on roads and surfaces that hasn't been gritted.

Instability comes from the difference in temperature between the two layers (warmer air rising). If both were the same temperature you have negative buoyancy (neutral really). The 850s are around -10 to -12 currently, and no air parcel is rising to 500 hPa via convection.

Snow has stuck round here to the pavements, and small quiet side roads. The main road is clear though.
Snowed pretty much all day, but no accumulations though.

This cant be tight surely.

BBC app giving me heavy snow tnrow for several hrs ??

The patio outside my french doors and conservatory is still a bit wet and the flakes melt on landing. It is weird, surely the ground must be freezing by now I've sent a different temperature sensor out there to check

[Polaris]

Just to highlight my previous posts. Heavy snow the past 4 hours of temps at -2c 

My front garden has gone from snow covered dry snow this morning, to patch green covered.

I had more snow on 24th Jan from a westerly with temps at plus figures. Can anyone shine a light?

Same for canterbury. Can’t be. I’d have thought showers were more likely than heavy snow ! North Sea hopefully will bring us some delights tonight 

[ItNeverSnowsInWindsor]

We need some surprises soon before it turns drier midweek!

[ItNeverSnowsInWindsor]

Got moderate snow falling now, need it to settle!!

[Nimbusman]

Right on cue the convection is getting going now, could be some decent falls this afternoon and evening

The chances are slim on that. Highest chance is 14%

[Howie]

The melting is very strange, literally can't think of any reason why it's melting on contact when it's -1

Be delighted if it were to happen..

Love this proper drifting snow, every now and then it blows straight off my back roof into the garden, time to sit in front of the roaring log fire and put the christmas lights on my Christmas tree in the back garden, my neighbour must think im nuts.
