mmm - you can tell from my previous post I was thinking the same! I thought
I saw a couple of flakes in the wind but it might have been because it
looked and felt so obviously that there should be. ;-)

I also thought I saw a few snow grains blowing in the wind in London
around 2pm.

As for Richard's query, the whiteness on the roads this morning was
simply down to hoar frost. I noticed it too - enough for car tracks to
be quite visible, and untreated pavements especially had a thick white
covering. It wasn't snow, though, simply a case of moister air coming
in during the night with the cloud, I think, and forming rime on the
very cold surfaces. Quite impressive and very wintry-looking though!

The odd thing was that the grass was nowhere near as white, which is the
reverse of what one normally sees with hoar frost.
