Such a shame this set up wasnt a few weeks later,had hail last night,and its been a sleety,graupel,rain mixture all day

Nothing to do with being a few weeks too early, more to do with the airmass not quite cold enough to produce snow to lower levels. On this date in the morning of November 1985 there was 2-5cm of snow across parts Kent and East Sussex, the easterly back then contained deeper cold though -10C at 850mb and below across the SE.

Been snowing in Paris this morning, so warming over the seasonally warm English Channel and North Sea SSTs not helping too.

looks like the streamer is losing intensity right as it becomes cold enough for snow. Reckon it will pipe up again this evening?

[Daenerys]

Slight snow flurries up in Tadworth/Epsom Downs earlier this àfternoon.

[TheGate]

1.8c now and definitely sleety. Need more intensity and should be some fun.

Left the Chilterns at 610ft ASL 2 degrees up there and sleet, now back home 62ft ASL and its 3 degrees but still sleetly 

Looks like as the night goes on the high RES models lift the streamers North and kill them off

4.7C in Hastings according to my thermometer

Really heavy shower with snow!!! 

[Nick F]

Area of rain/sleet/snow moving WNW out of Belgium may have Kent and London's name on it for later, be interesting to see if it turns to snow.

Oh damn, snow and proper graupel now... 

[lassie23]

no sleet or snow or indeed beef in the showers here, just plain rain.

Looking at this radar

could be exciting in the early hours for south of London.

I never trust them future radar grabs. What data do they even feed of? Does anyone know? 

Having said that, GFS and arome show some snow South of London tonight..

Not sure mate

but does tie in with the precipitation over Belgium right now

we can hope 

[snowray]

Temp at Kenley @ 17.00 just dropped to 1c, we just need temps to stay around there this evening in the SE and it could be game on for maybe even some settling snow on higher ground anyway!

[snowray]

The Arome model is also going for it now, pretty High Res too.

[SMU]

PPN looks a tad far North V radar returns but early days yet

[Dbarb]

Looks like we have a Thames streamer setting up, my location looks too marginal but over the hill could be fun

[SMU]

Ignore that - PPN expanding so the spread is good!

Expecting sub 2c when I get home !!

Yes Intresting watching the last radar grabs, not forcast but that is nearly a perfect thames streamer.. It's actually been near perfect here all day in North Surrey for Thames streamers location according to mum it hasn't stopped raining sleeting all day

That streamer has been running straight through here, it's been raining non stop today. Oh my word, if only it was a degree or two colder, never happens when it's cold enough, usually end up in the holes here!

 

Just saw your post Surrey....Yes same here, this was the perfect set up alright.

[SMU]

Just leaving eltham 40M all rain

I wonder what WK will bring in 30 mins @230M!!!

[abruzzi spur]

Still light rain at 110m in Reigate.  2.2c, Dewpoint has fallen from 1.7c to 1.4c in the last 20 minutes.   Light breeze from the North East.

No it don't thats a myth, you need colder air now compared to later in winter.. Although colder the better... 

The issue here is the SST (Surface sea temps) and to a degree I would have thought to the land mass temperature is too high .. 

We have had zero cold till now to chill things down a bit hence its too warm. 

The uppers tonight are now the lowest they will get in this cold spell at around -6 or -7 if they were around -10 to -12 we would be in business but they are not.

Why is Paris seeing snow you ask? One because maybe the temperatures are a little lower and 2 there is about 2000 miles of land mass to the east of them! (over doing it a bit i think lol!) Not a 13-15c sea 40 miles away!

Bizarre comment.  December 2010, anyone?  Streamers galore producing snow.
