Bring me sunshine

Obviously, mentioning this it tempting fate in a major way, and if we have three days of wet, windy, miserable weather it's all going to be my fault - but here goes anyway.

The BBC's five-day weather forecast claims (today - Tuesday - at least) it's going to be sunny in London throughout the conference. The maximum temperature should be around 20 degrees with a light breeze, falling to just above 10 degrees overnight. It could hardly be better.

I just hope there isn't some cosmic balancing mechanism that means if the weather's good everything else will go wrong...
