Well, I am pleased to say that the Croydon snow shield has finally been breached!
Heavy snow since just after 10.00, which has just reduced in intensity, depth of 2-3cm.
Definitely the heaviest snowfall in 8 years (since 20th Jan 2013), and the first daytime snow since then, which was also a Sunday!
However, unless it keeps snowing for another hour or two, it is liable to all disappear before the end of the day, and therefore go down as another transient spell of snow...
