[80sWeather]

Typical just decided to hit the sack and now its snowing!

Going to have to check lamp post every 5 mins, and wake Mrs up.

[80sWeather]

Other day i said i won't be doing snow maps! had to go back on that(for now) as i find it easier to draw and show an image, but will also later if i have time say the areas to be affected, just seeing how things go and then later il let you know if i can!

Some good precip coming up from the south now on radar.

Hello all!! Currently sat at Thailand airport trying to find out how bad weather is around Heathrow!!

[ChillyJuju]

Everyone gave up & went to bed, even I got miffed and turned the radar off, xbox on...45 mins later I glanced outside to see it pelting down with snow!

Settling fast on grass and sticking nicely to East facing surfaces, lamp post included.Peeked at radar again & it's whooshing up from the Channel,there may be some surprised but happy campers in the morning

[alexisj9]

Got ice pellit sleet now, hoping for transition soon. But got to get some sleep.

[lewis028]

Heavy snow in basildon

[Allezwasps.]

Teeming down with rain in bracknell.

[john pike]

Soaking wet. But is snowing now and laying on cars. Would not expect laying elsewhere at moment. More worried about flooding

[Callie]

Constant rain here and getting quite flooded in places!!

[snowking]

Well I've just woken up with pretty severe heartburn, so it's a good job there's some lovely cold snow outside to help ease it

Currently a covering on cars, roofs etc. Looking at some of the echoes on the radar to the south, I'm hoping we can get some snow cover down on concrete before dawn, though its all still a bit wet on there just at the moment.

Looking at some of the early data it looks as though things will indeed make it south of the river as we move through the day and into this evening, so we could see a good covering down towards London and Kent as the day goes on.

I suffer with that frequently, can't lay down it burns so much have to take tablets for it, if you can drink milk have a little bit it might help, sit up in bed until it goes. Anyone that has rain i am expecting the rain to turn to snow through this morning and afternoon unless your near the south coast or southwest Hampshire, as not quite cold enough until later today.

420GMT radar snap..

1mm=1cm snow ,approx

[snowking]

Cheers ES. Yep sat up in bed at present milk in hand and gaviscon will be sought after very shortly

Some very impressive radar echo's to both the east and west of the region at the moment, with the flow beginning to align more E to W through the morning and into the afternoon (at present it's curved SE-NW to S-N)

Up for work, and not at all surprised. Still wet outside on roads and pavements, thin cover of snow on grass and cars. It looks like very fine snow falling at the min, but there is also splashes in the puddles, so must be sleety. I never believe the hype anyway,because I know my area !

[Mark Neal.]

20p sized flakes here at moment.

[Mark Neal.]

Is that precip just into Berks. Looks heavy is that expecting to move North-Westwards?

[andreas]

Temperature has dropped 0.5 degrees in past hour, now 1.3 and dew point 0.0.

Snow beginning to settle on car windscreens. If the temperature drops another half degree, it could be an interesting day.

[crazysnowcatz4]

Snow just starting in Canterbiry 50p size flakes atm instantly laying as it is0C

[ZONE 51]

A look ahead at Sunday's snow risk and is it going to snow on the south coast..

Here is upper temps 850s

Image 1 -

1200hrs

This shows the upper temps not quite cold enough for snow along the South coast and SW Hampshire.

But take a look at image 2

0000hrs(midnight tonight)The colder temps get to the South coast, but it depends on what precipitation there is around when the cold enough temperatures arrive on near and on the SCoast.

--

Next is the dew points for 0600hrs Sunday

Just radar watching for snow by this time across all areas.

but will there be any around? taking alook at the ppn charts for Sunday

This is an easterly flow very cold and severe wind chill,

0600hrs Sunday - indications are light snow across the SE/EA.

next is NAE ppn snow/rain chart for 0000-0600hrs Sunday

This shows snow across most of EA/SE.

0600-1200hrs Sunday(above)snow spreads across most areas of SE/EA heaviest to the north of London.

1200hrs-1800hrs-snow spreading across through Sunday into Central South, this chart indicates mostly light snow.

For the South coast the very cold air/upper temps get there this weekend but it's the amounts of ppn that is what to watch for there by time it can snow. some say"it can pour down with rain but it hardly snows" "by time it turns to snow it fizzles out" this is because drier more stable air from higher pressure moves in, through next week high pressure would stop most snow from developing and become dry for a while but snow risk increases again later, we could find another battle from the Atlantic taking hold, the block in the north of the UK not shifting just yet.

Coming down moderately now. 4/10

[fatyido]

Moderate steady snow now. At last its just starting to settle on the roads and pavements slowly turning them white...

[crazysnowcatz4]

To add to my last post on the Murr scale it would be 7 - 8 /10 at least
