I always have a problem with % rain chance forecasts.

If you have a 50% chance of rain for 4 consecutive hours, surely you'd expect rain on 2 of them, if not it's wrong (one way or the other).
It's one area where I preferred the old system, scattered showers, frequent heavy showers, that sort of thing.
No rain here today, in fact only 0.8mm so far this month.
