There is some very heavy precipitation south of Oxford; you might be under that now. That should give a lot if it stays as snow.

I've just been out to move the car, and what seems to be coming out of the sky is a mixture of moderate rain and half-melted ice pellets.     

The same area connected to the bit going through weybridge is heavy icy rain.

Sheffield. 

So far it has stayed as snow, and is chucking it down - pleasantly surprised! 

Also if you look at the radar now you can clearly see the ever faithful M4 corridor or more accurately the course of the Thames from the Estuary westwards to its source. Also noting how marginal it is it is rain over my relatively narrow stretch of the estuary and snow just to the North and Southend is 2C warmer than here just 25 miles East and on  the coast.

I was going to say?? like what? Daytime and Hertfordshire having snow cover and so soon in the day!?

Looks colder because in London it was 37'F and now it's dropped to 31'F with light fluffy powdery snow looking at Abbey road live webcam:

T: -0.2°C, DP: -0.4°C.

At least you seen the snow but sad how by the time you wake up it will all be gone and temps will be up to +10c - all those kids dreaming of the "day off" being a Sunday yet the warm airmass ruins things as ever!

Streets now white on Abbey Road

Yes, it was very good. Brings back some nostalgic memories which we have been discussing in the other thread Brian started about Maid of Orleans. 

Hard to believe how we managed to cope with the regular power cuts in those days. I remember my parents used to use the kitchen gas hob as a heat source as well as for cooking.  We still had phone lines as well which could work without electricity (no longer possible with BT switching to Digital Voice via the router) 

How could we cope now in a powercut? Very badly I think. 

We had ice pellets in Exeter at around 15:00 - 17:00 in Okehampton there was sleety snow but then heavy rain.

Just shows that even that 0.1c increase in temperature can cause heavy snow to become rain with ice pellets as you observed above. BTW how do you measure the DP's?

Make the best of the snow - it's a balmy 11c in Okehampton crazy to think 6 hours ago we were barely above freezing and just 60 miles north it's still 0c with heavy snow (i.e Wales).

I just read it off my weather station, but there is a formula for the dewpoint. https://www.wunderground.com/dashboard/pws/IWATFO32

This photo was taken just after midnight when the snow was the heaviest. https://www.flickr.com/photos/alalchan/54246083732/in/dateposted-public/

Great photos there Andrew - I think its more of a shame for any children in particular, who hardly seen snow and would have gone to bed by 20:00 when it was raining and woken up to nothing and, or worst of all seen it all white before bed, then and waking up by 07:30am when all the snow had melted by then and consequently would have missed all the fun of snow over night. Hope their parents are taking photos of the snow, esp in the south for proof that there was snow. Just sad really and it's on a Sunday too when they don't have classes and could have enjoyed it. Always another time...I guess!

Sadly Google's Nest cameras aren't as good as the one on their phones, but leaving the bathroom light on meant there was just enough light to see the snow.

Yes, that would be my estimate just looking out of the window. Light snow falling now. But when will the milder air get here?
