There was a light dusting of snow overnight in Croydon, but it's barely settled on the cars and plants. Anything on the ground has melted.
It's not going to stop me cycling into work, I've got the studded tyres on Vince, so even if the temperature take a significant dive from the -1.7°C I'm currently seeing for Biggin Hill, it's not going to make any difference to me.
Heathrow and Gatwick are reporting a balmy 0°C, so it's not particularly cold out there. I may put some gloves on.
