It's snowing (Weather Conditions week commencing 2nd Feb 2009)

Not a bad ride in. Minor roads are very icy. Plenty of balck ice. Try to stick to busier roads.
Main roads are wet but no longer icy. As you get to central London, ice disappears; minor roads are slushy.
Bus lanes still have ice but this will probably disappear as more buses get moving. Best to stick to main lane for a while. Cars still being unusually civil. Only one bus driver tried to kill me. Not bad for a morning commute.

Thanks for an actually useful weather/traffic report.
