30% Chance of Rain?
I listen faithfully to the weather forecast for our area every morning, but I'm blowed if they are ever right about the rainfall. The temperature is normally accurate - within a degree or two and they are pretty good about wind speed but 30% chance of rain? Maybe I don't know how to interpret the language. Does it mean that 70% of the day will be dry and that for 30% of the time it will rain - or does it mean there is only a 30% chance that there will be any rain at all - or for those of you optimists that believe the glass is half full - that most of the day will be sunny? What do the statisticians say?
